Description

Technical Field

[0001] This utility model relates to an activated coke material conveying and ash removal device, belonging to the technical field of conveying devices. Background Technology

[0002] In the current activated coke material circulation process, friction, collision and compression of the material in the desorption tower, adsorption tower and conveyor generate a lot of dust and fine particles. The entire material circulation system only has a dust removal device before entering the desorption tower. There is no dust removal device before the subsequent chain bucket conveyor conveys the material into the adsorption tower module. As a result, there is a lot of dust in the adsorption tower module. The module is prone to hot spots and the dust emission at the outlet is likely to exceed the standard. The activated coke is covered with a layer of dust, which also affects the adsorption capacity. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an activated coke material conveying and ash removal device that is easy to operate, can remove dust and fine particles, and improve the adsorption capacity of activated coke.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: an activated coke material conveying and ash removal device, including an outer chute, which is connected between the material conveying hopper of a chain bucket machine and a buffer tank; an inner chute is set in the center of the inner cavity of the outer chute, and the inlet of the inner chute is connected to the outlet of the conveying hopper; a grid is set inside the outer chute, and the grid is set below the outlet of the inner chute; an air inlet unit and a dust removal unit are provided on the outer chute, the air inlet unit is set below the grid, and the dust removal unit is set above the grid.

[0005] The air intake unit includes multiple circumferentially distributed air inlets, each of which is connected to an air intake pipe.

[0006] The dust removal unit includes multiple circumferentially distributed dust removal ports, each of which is connected to a dust removal pipe.

[0007] The gaps on the grille are all 4-7cm.

[0008] An inspection port is provided on the outer chute, the inspection port is located above the grille, and an inspection door is hinged to the inspection port.

[0009] Compared with the prior art, the advantages of this utility model are: an activated coke material conveying and ash removal device is easy to operate, can effectively separate and remove fine particles and dust from activated coke materials, ensure that the material particles meet the requirements, improve the adsorption capacity of activated coke, and prevent excessive dust from entering the module output hot spot and the outlet dust emission from exceeding the standard. Attached Figure Description

[0010] Figure 1This is a schematic diagram of an activated coke material conveying and ash removal device according to an embodiment of the present invention;

[0011] In the diagram, 1 is the dust removal pipe, 2 is the inner chute, 3 is the outer chute, 4 is the inspection port, 5 is the grille, and 6 is the air inlet pipe. Detailed Implementation

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, an activated coke material conveying and ash removal device in this embodiment includes an outer chute 3, which is connected between the material conveying hopper and the buffer tank of a chain bucket machine. An inner chute 2 is welded to the upper center of the inner cavity of the outer chute 3 via a welding plate, and the inlet of the inner chute 2 is connected to the outlet of the conveying hopper. A grid 5 is welded to the inner cavity of the outer chute 3, and the grid 5 is located below the outlet of the inner chute 2. Dust removal ports are symmetrically opened at the upper end of the outer chute 3, and air inlets are symmetrically opened at the lower end of the outer chute 3. The dust removal ports are located above the grid 5, and the air inlets are located below the grid 5, forming air convection between the air inlets and dust removal ports. The air inlets are connected to air inlet pipes 6, and external air enters the outer chute 3 through the air inlet pipes 6. The dust removal ports are connected to dust removal pipes 1, creating a negative pressure inside the outer chute 3.

[0014] The gaps on the grid are all 5cm. The activated coke material falls onto the grid through the inner chute, separating the impurities in the activated coke material and preventing material splashing.

[0015] An inspection port 4 is provided on the outer chute, located 10cm above the grid 5, with dimensions of 100*100mm. An inspection door is hinged to the inspection port, allowing it to be opened or closed for easy cleaning of debris from the grid, preventing blockage of the grid gaps and ensuring proper material flow, thus avoiding disruption to the normal operation of the activated coke material conveying process.

[0016] The dust removal port is positioned flush with the center of the casing.

[0017] A 600mm diameter outer chute is installed between the material conveying hopper and the buffer tank of the chain bucket conveyor. A 1.5-meter-long, 400mm diameter inner chute is welded to the upper end of the outer chute. Dust collection ports on both sides of the outer chute are connected to dust collection pipes to form a suction system. A grid is installed 20cm below the bottom of the inner chute to disperse the material through collision. An air inlet is opened 30cm below the grid on the outer chute, creating cross-convection of gas inside the outer chute. This allows the suction from the dust collection pipes to remove accumulated dust from the material, achieving a dust removal effect.

[0018] This application is easy to operate and can effectively separate and remove fine particles and dust from activated coke materials, ensuring that the material particles meet the requirements, improving the adsorption capacity of activated coke, and preventing excessive dust from entering the module's output hotspot and exceeding the dust emission standards at the outlet.

[0019] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
