Description

Technical Field

[0001] This utility model relates to the field of harmless treatment technology of arsenic sulfide slag in non-ferrous metallurgy, and specifically discloses a harmless drying, unloading and crushing device for arsenic sulfide slag. Background Technology

[0002] Arsenic sulfide slag is a hazardous solid waste generated during the smelting or chemical process of arsenic-containing minerals (such as realgar and orpiment). Its main component is arsenic sulfide (As2S3 or As4S4), and it often contains heavy metals (lead, cadmium, mercury, etc.) and other sulfides (HW48 type). It has a high moisture content, strong viscosity and uneven particle size distribution.

[0003] Traditional crushing devices use a single-shaft hammer crushing structure, which causes material to adhere to the crushing chamber wall, resulting in poor unloading or even blockage. Furthermore, the uneven particle size affects the subsequent drying efficiency. Therefore, a harmless drying and unloading crushing device for arsenic sulfide slag is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a harmless drying and unloading crushing device for arsenic sulfide slag. Through the coordinated shearing and crushing design of staggered inclined material blocking rods and rotating crushing rods, combined with an explosion-proof motor and a semi-enclosed structure, it achieves efficient crushing and safe and harmless treatment of arsenic sulfide slag, effectively improving crushing efficiency and reducing environmental pollution risks.

[0005] This utility model is implemented as follows: a harmless drying and unloading crushing device for arsenic sulfide slag includes a discharge hopper and a receiving box with a discharge port at one end. The discharge hopper is equipped with a crushing mechanism, which includes multiple material blocking rods evenly distributed on the left and right sides of the inner wall of the discharge hopper, two rotating shafts rotatably connected to the front and rear sides of the inner wall of the discharge hopper, and multiple sets of crushing rods fixedly connected to the outer wall of the rotating shafts. The multiple material blocking rods are staggered with the multiple crushing rods, and both the material blocking rods and the crushing rods are inclined.

[0006] The outer wall of the unloading hopper is equipped with a drive mechanism.

[0008] As a preferred embodiment of the harmless drying and unloading crushing device for arsenic sulfide slag of this utility model, the unloading hopper and the outer wall of the receiving box are fixedly connected to a protective cover located outside the chain.

[0009] As a preferred embodiment of the harmless drying and unloading crushing device for arsenic sulfide slag of this utility model, the receiving box is equipped with a conveyor belt inside.

[0011] As a preferred embodiment of the harmless drying and unloading crushing device for arsenic sulfide slag of this utility model, a controller is provided on the outer wall of the unloading hopper, and the drive motor and conveyor belt are both electrically connected to the controller.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the coordinated action of the staggered inclined material blocking rods and the rotating crushing rods, a dual crushing effect of shearing and extrusion is formed, which greatly improves the crushing efficiency of arsenic sulfide slag, while avoiding material adhesion or blockage.

[0014] 2. The explosion-proof motor with IP55 protection rating and semi-enclosed structure design effectively prevent the risk of explosion caused by arsenic-containing dust or harmful gases, and reduce the environmental pollution caused by arsenic volatilization.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 The harmless drying and unloading crushing device for arsenic sulfide slag includes a discharge hopper 1 and a receiving box 2 with a discharge port at one end. The discharge hopper 1 is equipped with a crushing mechanism, which includes multiple material blocking rods 3 evenly distributed on the left and right sides of the inner wall of the discharge hopper 1, two rotating shafts 4 rotatably connected to the front and rear sides of the inner wall of the discharge hopper 1, and multiple sets of crushing rods 5 fixedly connected to the outer wall of the rotating shafts 4. The multiple material blocking rods 3 and the multiple crushing rods 5 are distributed alternately, and the material blocking rods 3 and the crushing rods 5 are all inclined.

[0022] The outer wall of the unloading hopper 1 is equipped with a drive mechanism.

[0023] In this embodiment: the drive mechanism drives the rotating shaft 4 to rotate the crushing rod 5, which works in conjunction with the material blocking rod 3 to crush the material. The crushed arsenic sulfide slag is discharged through the discharge port. The staggered inclined material blocking rod 3 and the rotating crushing rod 5 form a shearing and squeezing effect, which improves the crushing efficiency of the arsenic sulfide slag and avoids material adhesion or blockage. The fixed distribution of the material blocking rod 3 combined with the dynamic rotation of the crushing rod 5 enhances the uniformity of crushing and reduces equipment wear. The semi-enclosed design reduces the risk of arsenic volatilization and meets the environmental protection requirements for hazardous waste treatment.

[0024] As a technical optimization of this utility model, the drive mechanism includes a drive motor 8, the output end of the drive motor 8 is fixedly connected to a second sprocket 9, the front ends of the two rotating shafts 4 extend to the outside of the unloading hopper 1 and are fixedly connected to meshing gears 6, and the outer wall of one of the rotating shafts 4 is fixedly connected to a first sprocket 7, and the first sprocket 7 and the second sprocket 9 are connected by chain drive.

[0025] In this embodiment: the drive motor 8 is started, the drive motor 8 drives the second sprocket 9 to rotate, and then drives the first sprocket 7 to rotate through the chain. The first sprocket 7 further drives one of the rotating shafts 4 to rotate, and then drives the other rotating shaft 4 to rotate synchronously in the opposite direction through the gear 6, thereby driving the crushing rod 5 to rotate to crush the arsenic sulfide slag.

[0026] As a technical optimization of this utility model, the outer walls of the unloading hopper 1 and the receiving box 2 are fixedly connected with a protective cover 10 located outside the chain.

[0027] In this embodiment, the protective cover 10 is provided to protect the transmission components and prevent operators from being injured by machinery.

[0028] As a technical optimization of this utility model, the receiving box 2 is equipped with a conveyor belt 11.

[0029] In this embodiment, the conveyor belt 11 facilitates the discharge of the crushed arsenic sulfide slag from the receiving box 2.

[0030] As a technical optimization of this utility model, the drive motor 8 is an explosion-proof motor with an IP55 protection rating.

[0031] In this embodiment: arsenic-containing dust or volatile harmful gases (such as arsine) may be generated during the crushing of arsenic sulfide slag, posing an explosion risk to ordinary motors. Explosion-proof motors, through their sealed structure and special design, prevent electrical sparks from igniting explosive environments, ensuring safe operation under high-risk conditions.

[0032] As a technical optimization of this utility model, a controller is provided on the outer wall of the unloading hopper 1, and the drive motor 8 and the conveyor belt 11 are both electrically connected to the controller.

[0033] In this embodiment, the controller facilitates the normal operation of the drive motor 8 and the conveyor belt 11.

[0034] The working principle and usage process of this utility model are as follows: During use, the drive motor 8 and conveyor belt 11 are started. The drive motor 8 drives the second sprocket 9 to rotate, which in turn drives the first sprocket 7 to rotate via a chain. The first sprocket 7 further drives one of the rotating shafts 4 to rotate, which in turn drives the other rotating shaft 4 to rotate synchronously in the opposite direction via a gear 6. This causes the crushing rod 5 to rotate, pouring the arsenic sulfide slag into the discharge hopper 1. The crushing rod 5 and the blocking rod 3 work together to crush the material. The crushed arsenic sulfide slag is discharged through the outlet. The staggered and inclined blocking rods 3 and the rotating crushing rod 5 form a shearing and squeezing effect, improving the crushing efficiency of the arsenic sulfide slag and preventing material adhesion or blockage. The fixed distribution of the blocking rods 3 combined with the dynamic rotation of the crushing rod 5 enhances the uniformity of crushing and reduces equipment wear. The semi-enclosed design reduces the risk of arsenic volatilization and meets the environmental protection requirements for hazardous waste treatment.
