Description

Technical Field

[0001] The utility model relates to the technical field of arsenic residue recovery, and specifically relates to a pyrolysis recovery device with a pretreatment function. Background Technique

[0002] Arsenic waste residue is an arsenic-containing solid waste, mainly from the processes of mining, beneficiation and smelting of non-ferrous metals, sulfuric acid preparation, and the preparation and use of early pesticides. In these wastes, arsenic is a sulfurophilic element and is often associated with non-ferrous metal minerals such as copper, lead, and zinc.

[0003] In the existing treatment of arsenic waste residue, heating is carried out through a forging furnace. The waste residue burns fully, and after burning, it turns into gas. Then, through a gas treatment device, these harmful gases are treated. However, during combustion, because the arsenic waste residue may accumulate together, the combustion is very slow, resulting in a slow treatment efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pyrolysis recovery device with a pretreatment function to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A pyrolysis recovery device with a pretreatment function, including a forging furnace body for calcining arsenic waste residue. An exhaust hole is fixedly installed on the right side of the forging furnace body, which can discharge the arsenic waste residue that has turned into gas. A feeding plate is fixedly installed on the left side of the forging furnace body to facilitate the pouring of arsenic waste residue into the forging furnace body. A shaking mechanism is arranged inside the forging furnace body, which can disperse the agglomerated arsenic waste residue and make the combustion more uniform and sufficient. The shaking mechanism includes:

[0006] A motor, the bottom of the motor is fixedly installed on the top of the forging furnace body, and the output end of the motor is fixedly installed with a rotating shaft to facilitate driving the main rotation of the gear disk.

[0007] A gear disk, the gear disk is fixed on the outer wall of the rotating shaft, and a chute is opened on the outer wall of the rotating shaft.

[0008] Preferably, a sliding rod is slidably installed inside the chute to facilitate the installation of a stirring rod. A moving spring is fixedly installed at the bottom of the sliding rod, which can reset the sliding rod after it moves downward. One end of the moving spring away from the sliding rod is fixedly installed at the bottom of the chute. A stirring rod is fixedly installed on the front of the sliding rod, which can disperse the arsenic waste residue in the forging furnace body.

[0009] Preferably, a convex block is fixedly installed on the inner wall of the forging furnace body, which can cause the stirring rod to be extruded downward when it rotates. A rotating rod is fixedly installed on the inner wall of the feeding plate, and a rotating rod is rotatably installed on the outer wall of the rotating rod, which is convenient for installing the filter screen. The filter screen is hingedly installed at the top of the front of the rotating rod.

[0010] Preferably, a pressing rod is hingedly installed at the bottom of the front of the rotating rod, which can drive the rotating rod to rotate on the rotating rod. A reset spring is fixedly installed on the left side of the pressing rod, which can reset the pressing rod after being extruded. One end of the reset spring away from the pressing rod is fixedly installed with a fixing block, and the back of the fixing block is fixedly installed on the back of the feeding plate.

[0011] Preferably, two groups of the rotating rod, the rotating rod and the reset spring are provided, and they are symmetrically distributed on the front and back sides of the feeding plate with the central axis of the feeding plate as the axis of symmetry, which can better make the filter screen shake and is convenient for fixing the filter screen.

[0013] Compared with the prior art, the utility model provides a pyrolysis recovery device with a pretreatment function, which has the following beneficial effects:

[0014] 1. For the pyrolysis recovery device with a pretreatment function, when the arsenic waste residue is poured into the feeding port in a mass, the arsenic waste residue is first poured onto the filter screen. By starting the motor to drive the rotating shaft to rotate, the toothed disk rotates, the toothed disk presses the pressing rod, the filter screen moves, and then resets through the reset spring, so that the filter screen shakes, and the massed arsenic waste residue is shaken loose. Through the stirring of the stirring rod, the arsenic waste residue can be fully burned in the forging furnace body, which can accelerate the combustion efficiency and improve the treatment efficiency of the arsenic waste residue.

[0015] 2. For the pyrolysis recovery device with a pretreatment function, when the arsenic waste residue is in the forging furnace body, through the rotation of the rotating shaft, the stirring rod can rotate.

[0023] As Figures 1-6 shown, the present utility model provides a technical solution: a pyrolysis recovery device with a pretreatment function, including a forging furnace body 1. An exhaust hole 2 is fixedly installed on the right side of the forging furnace body 1, which can discharge the arsenic waste residue that has become gas. A feeding plate 3 is fixedly installed on the left side of the forging furnace body 1, which is convenient for feeding the arsenic waste residue into the interior of the forging furnace body 1. A shaking mechanism 4 is arranged inside the forging furnace body 1, which can disperse the agglomerated arsenic waste residue and make it more uniform and sufficient during combustion.

[0024] Specifically, the jitter mechanism 4 includes: a motor 41, a rotating shaft 42, a toothed disk 43, a chute 44, a slide bar 45, a moving spring 46, a stirring rod 47, a bump 48, a rotating rod 49, a rotating lever 410, a filter screen 411, an extrusion rod 412, a return spring 413, and a fixing block 414. The bottom of the motor 41 is fixedly installed on the top of the forging furnace body 1 and can drive the rotating shaft 42 to rotate. The output end of the motor 41 is fixedly installed with the rotating shaft 42, which facilitates the installation of the toothed disk 43 and the slide bar 45. The outer wall of the rotating shaft 42 is fixedly installed with the toothed disk 43, which can press the extrusion rod 412 to move. The outer wall of the rotating shaft 42 is provided with a chute 44, which facilitates the installation of the slide bar 45. The slide bar 45 is slidably installed inside the chute 44, which facilitates the installation of the stirring rod 47. The bottom of the slide bar 45 is fixedly installed with the moving spring 46, which can make the slide bar 45 move downward and then reset. The end of the moving spring 46 away from the slide bar 45 is fixedly installed at the bottom of the chute 44 for fixation. The front of the slide bar 45 is fixedly installed with the stirring rod 47, which can disperse and stir the arsenic waste residue in the forging furnace body 1. The chute 44, the slide bar 45, and the stirring rod 47 are arranged in a circumferential array centered on the rotating shaft 42, and there are three groups. This can disperse the arsenic waste residue in the forging furnace body 1 better. The inner wall of the forging furnace body 1 is fixedly installed with a bump 48, which can squeeze the stirring rod 47 to drive the slide bar 45 to move downward. The inner wall of the feeding plate 3 is fixedly installed with a rotating rod 49, which facilitates the installation of the rotating lever 410. The rotating lever 410 is rotatably installed on the outer wall of the rotating rod 49, which facilitates the installation of the filter screen 411 and the extrusion rod 412. The filter screen 411 is hingedly installed at the top of the front of the rotating lever 410, which can disperse the agglomerated arsenic waste residue during jittering and make it burn more fully. The extrusion rod 412 is hingedly installed at the bottom of the front of the rotating lever 410, which can drive the rotating lever 410 to rotate. The left side of the extrusion rod 412 is fixedly installed with the return spring 413, which can make the extrusion rod 412 reset after being squeezed. The rotating rod 49, the rotating lever 410, and the return spring 413 are provided in two groups and are symmetrically distributed on both sides of the front and back of the feeding plate 3 with respect to the central axis of symmetry of the front of the feeding plate 3. This can make the filter screen 411 jitter better and facilitate the fixation of the filter screen 411. The end of the return spring 413 away from the extrusion rod 412 is fixedly installed with a fixing block 414, which facilitates the fixation of the return spring 413. The back of the fixing block 414 is fixedly installed on the back of the feeding plate 3.

[0025] Working principle: When the arsenic waste residue is poured into the feeding plate 3 in a mass, first pour the arsenic waste residue onto the filter screen 411. By starting the motor 41 to drive the rotation of the rotating shaft 42, the toothed disk 43 rotates, the toothed disk 43 squeezes the extrusion rod 412, the articulated rotating rod 410 is pushed to rotate on the rotating rod 49, and the filter screen 411 moves. The return spring 413 is compressed on the fixed block 414. When not squeezed by the toothed disk 43, the return spring 413 can drive the extrusion rod 412 to reset, so that the filter screen 411 can vibrate, the mass of arsenic waste residue can be shaken loose, and the shaken-off arsenic waste residue slides from the bottom of the feeding plate 3 into the forging furnace body 1. Then, through the stirring of the stirring rod 47 driven by the rotating shaft 42, the arsenic waste residue can be fully burned in the forging furnace body 1 and then turned into gas and discharged from the exhaust hole 2, which can accelerate the combustion efficiency and improve the treatment efficiency of the arsenic waste residue.

[0026] When the arsenic waste residue is in the forging furnace body 1, through the rotation of the rotating shaft 42, the stirring rod 47 can be driven to rotate. When the stirring rod 47 rotates, it is squeezed downward by the convex block 48, which drives the sliding rod 45 to slide in the sliding groove 44 and move downward, and the moving spring 46 is compressed. When not squeezed, the moving spring 46 will drive the sliding rod 45 to reset, so that the sliding rod 45 can move up and down. In this way, the stirring rod 47 can rotate and move up and down, which can disperse the arsenic waste residue in the forging furnace body 1, improve the combustion speed of the arsenic waste residue, and improve the treatment efficiency.

[0027] The above text has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
