Description

Technical Field

[0001] The utility model relates to the technical field related to gas slag removal, in particular to a gas slag removal device. Background Art

[0002] In the process of industrial gas production and processing, it is necessary to heat the raw materials inside the reactor in the furnace body. As the raw materials are heated, dust and other waste residues generated by the raw materials will also diffuse with the movement of the gas. Therefore, in order to ensure the quality of the gas, a slag removal device needs to be provided at the outer end of the reactor to prevent the waste residues generated by the raw materials from overflowing. However, the existing reactor slag removal device still adopts a relatively simple filter screen and other structures. As a result, when the raw materials are heated, the waste residues generated by the raw materials will quickly cause the filter screen to become blocked, which in turn requires the staff to clean and replace the filter at a high frequency. This will obviously cause a waste of time and physical strength of the staff, and will also lead to a decrease in gas processing efficiency. For this reason, we propose a gas slag removal device. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The gas slag removal device is provided with a recoil frame on the surface of the filter screen. Through the connection between the recoil pipe and the dust guide pipe, when the motor drives the recoil pipe and the recoil frame to rotate, the waste slag on the surface of the filter screen can be pushed into the recoil frame, and the waste slag can be led out to each other through the recoil pipe and the dust guide pipe. There is no need to frequently disassemble the filter screen, which reduces the waste of time and physical strength of the staff and improves the gas processing efficiency.

[0012] The gas slag removal device is provided with a sealing ring and a sealing plate, and a spring is arranged between the two. When the reactor is heated, the air moving due to thermal expansion and contraction can push the sealing plate to move, thereby opening the sealing plate, so that the reactor gas and impurities can enter the filter. When the heating of the reactor stops, the sealing ring and the sealing plate fit together, which can prevent the waste residue inside the filter from flowing back into the reactor.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-7 The utility model provides a technical solution: a gas slag removal device, comprising a reactor 1 embedded in a furnace wall, a filter 2 and a collector 11 are plugged and installed on the outer end of the reactor 1, the reactor 1 is connected to the inner cavities of the filter 2 and the collector 11, a filter screen 21 is fixedly installed in the filter 2, a dust guide pipe 22 is fixedly installed on the periphery of the filter 2, a recoil pipe 23 is rotatably installed on the middle part of the filter screen 21, the recoil pipe 23 and the dust guide pipe 22 are rotatably connected to each other, a recoil frame 24 is fixedly installed on the front end surface of the recoil pipe 23, the recoil frame 24 and the filter screen 21 are in contact with each other near the end surface, a motor 26 is fixedly installed on the periphery of the filter 2, and the output shaft of the motor 26 is meshed and connected with the recoil pipe 23.

[0027] Working principle: start the motor 26, and connect the outer end of the dust guide pipe 22 to the external waste residue recovery device, and heat the reactor 1 and the raw materials inside the reactor 1 through the furnace body. The raw materials are heated to generate gas and waste residue. Through the thermal expansion and contraction of the gas, the gas drives the waste residue to expand outward into the filter 2, and passes through the filter screen 21 from front to back. The waste residue can be blocked by the filter screen 21, and the started motor 26 drives the recoil pipe 23 to rotate through its lower end output shaft, thereby driving the recoil frame 24 to rotate on the surface of the filter screen 21. At the place where the recoil frame 24 and the filter screen 21 are aligned with each other, at the filter screen 21, the gas passes through the filter screen 21 from back to front, and pushes the waste residue on the surface of the filter screen 21 into the recoil frame 24. In conjunction with the recoil pipe 23 and the dust guide pipe 22, the waste residue can be guided to the external waste residue recovery device to complete the waste residue recovery.

[0028] As a further description of the above technical solution: a limited rotating ring 29 is fixedly installed in the filter 2 through a connecting rod, and an annular rotating block 291 rotatably connected to the inner cavity of the limited rotating ring 29 is fixedly installed on the periphery of the recoil pipe 23; a through cavity 211 is opened in the filter net 21, and the recoil pipe 23 is rotatably installed in the through cavity 211; a limited rotating seat 28 is fixedly installed at one end of the dust guide pipe 22; a first bevel gear 27 is fixedly installed on the lower end of the motor 26 through its output shaft, and the first bevel gear 27 is rotatably connected to the limited rotating seat 28; a second bevel gear 25 meshingly connected to the first bevel gear 27 is fixedly installed on the periphery of the recoil pipe 23; a valve body 3 is fixedly installed in the filter 2, and the valve body 3 is close to one side of the collector 11; a valve flap 31 is rotatably installed in the valve body 3; a driving ring 32 is provided on the periphery of the filter 2, and the lower end of the driving ring 32 is fixedly connected to the rotating shaft of the valve flap 31 through a connecting rod.

[0029] Specifically, the movement direction of the recoil tube 23 can be limited by the rotational connection between the limit rotation ring 29 and the annular rotation block 291;

[0030] A through cavity 211 is provided to increase the installation and rotation space of the backwash pipe 23 and avoid interference between the rotating backwash pipe 23 and the filter screen 21;

[0031] A limit rotating seat 28 is provided to limit the movement direction of the first bevel gear 27. Through the meshing connection between the first bevel gear 27 and the second bevel gear 25, the motor 26 can drive the recoil tube 23 to rotate through its output shaft;

[0032] The drive ring 32 is provided to drive the valve flap 31 to rotate in the valve body 3, so as to seal the filter 2 and prevent the air inside the filter 2 from overflowing when the collector 11 is disassembled and the gas is recovered.

[0033] As a further description of the above technical solution: a sealing ring 4 is fixedly installed in the filter 2, the sealing ring 4 is close to one side of the filter 2, and a sealing plate 41 is plugged and installed on the opposite side of the sealing ring 4 and the filter 2. The outer periphery of the sealing plate 41 is gap-matched with the inner wall of the filter 2, and a connecting seat 42 is fixedly installed on the outer periphery of the sealing plate 41, and a spring 46 is fixedly installed between the sealing ring 4 and the connecting seat 42. A limiting hole 43 is provided in the middle of the connecting seat 42, and a limiting rod 44 plugged into the limiting hole 43 is fixedly installed on the surface of the sealing ring 4, and a connecting plate 45 is fixedly installed on the outer periphery of the limiting rod 44, and a spring 46 is fixedly installed between the connecting seat 42 and the connecting plate 45, and the spring 46 is sleeved on the outer periphery of the limiting rod 44.

[0034] Specifically, when the raw materials in the reactor 1 are heated so that the gas diffuses into the filter 2, the moving gas pushes the sealing plate 41 to move, so that the sealing plate 41 is separated from the sealing ring 4, so that the moving gas can enter the filter 2 from the gap between the sealing plate 41 and the sealing ring 4;

[0035] When the heating of the reactor 1 stops, the gas inside it no longer diffuses outward stably due to thermal expansion and contraction. At this time, the spring 46 restores its deformation and drives the sealing plate 41 to reset, so that the sealing plate 41 and the sealing ring 4 fit together again, preventing the waste residue inside the filter 2 from flowing back into the reactor 1.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
