ZKC block type heavy chain Cleaner

frame-chain slag remover suitable for small thermal power plants, district heating or continuous removal of ash and slag from coal-fired steam and hot water boiler rooms,suitable for combined slag removal of multiple boilers in series. This equipment can be used not only for wet slag removal that requires water sealing and cannot leak air into the furnace, but also for dry slag removal of circulating fluidized bed boilers used with slag coolers.

 

Frame-chain slag remover according to the casing type, there are two types of trench type (concrete trough type) shown in figure 1 and shell slot type (steel casing type) shown in figure 2. According to the different discharge heights of the head, there are two types of low-level discharge and high-level discharge. Figures 1 and 2 are the standard design of the low-level discharge method of the trench and trough shell.

Frame-chain slag remover’s motor used is divided into fixed speed and variable speed.

Among them, the variable speed motor is divided into two types: electromagnetic speed regulating motor and frequency conversion adjusting motor.

 

The frame-chain slag remover is a kind of continuously running slag conveying device and is composed of a drive mechanism, drag mechanism, tail roller steering mechanism, slag trough, chain and idler roller. 

The drive mechanism is composed of a motor, a cycloidal planetary gear speed reducer, a drive sprocket and a tension slide. The drive mechanism is of knapsack type, has a good stress-bearing capacity on the whole and is convenient for installation and adjustment. The drag sprocket gear plate is detachable and thus is convenient for replacement. Base chain and winged chain are both adopted. ZKC-260 frame-chain slag remover is designed with only base chain, while ZKC-350 frame-chain slag remover and above specifications are designed with two base chains and one winged chain. 

The wear-resistant and corrosion-resistant basalt cast stone slab lining at the bottom of the machine slot greatly extends the service life of the housing and also reduces the wear of the frame chain. 

 

According to the size of the slag, choose a slag remover with matching specifications according to the attached table in Figure 1 and Figure 2.

FIGs. 1 and 2 show the standard sizes of the transition arc radius of the discharge height and the height of the inclined lifting section of two types of the housings respectively. 

The discharging mode of the slag remover, the sizes of the transition arc radius and the height of the inclined lifting section should be selected based on the surrounding conditions of the boiler room. The radius of transition arc R should be larger than 8m, and the optimal height of the inclined lifting section within 20°. Long inclined section and large lifting height is recommended for wet slag removal, and the dewatering effect of the inclined section of the slag conveyor is used to make ash shipment more environment-friendly. If the slag conveyor directly transports ash to the slag silo for secondary dewatering, better effect will be produced. 

When placing an order, in addition to selecting and defining the above terms, please make clear the spacing a, b, c, d, e... among boiler slag discharge ports illustrated in FIGs. 1 and 2, and the positioning dimension k of the starting line of the transition arc. Our company can provide field measurement, design and model selection services of the system equipment, and provide equipment of non-standard design and supporting auxiliaries related to the system equipment.
