Description

Technical Field

[0001] This utility model relates to the field of closed feeding technology, and in particular to a closed feeding and dust removal system for powder raw materials used in the production of chemical additives for oil and gas fields. Background Technology

[0002] In the production of chemical additives in oil and gas fields, the closed feeding and dust removal system for powder raw materials is an important equipment system to ensure production safety, reduce environmental pollution, and improve production efficiency. During operation, powder raw materials are drawn from raw material barrels or storage tanks and transported to production equipment such as reaction vessels and batching vessels through equipment such as vacuum feeders, pneumatic diaphragm pumps, or closed screw conveyors. The entire feeding process is carried out in closed pipelines or containers to avoid direct contact between powder raw materials and outside air and reduce dust leakage.

[0003] When feeding powder raw materials in a sealed manner, many powder raw materials (such as calcium carbonate, ammonium sulfate, starch and other powders) have strong hygroscopicity. In high humidity environments, powder raw materials are prone to absorbing moisture from the air and clumping. However, clumped powder may affect production efficiency during the sealed feeding process and may also cause equipment damage and safety hazards.

[0004] Therefore, how to design a closed feeding and dust removal system for powder raw materials used in the production of chemical additives for oil and gas fields that can handle agglomerated powders is a technical problem that technicians need to solve. Utility Model Content

[0034] The material cylinder 1 and the crushing mechanism 2 are provided. The bottom of the material cylinder 1 is provided with a pipe 3. The crushing mechanism 2 includes a main cylinder 201, a grinding block 206 for crushing agglomerated powder, and a fixing support plate 213 for supporting and fixing the position of the main cylinder 201. The main cylinder 201 is installed inside the pipe 3.

[0035] Specifically, a fixed cylinder 202 is provided at the bottom of the main body cylinder 201, and an installation groove 204 is provided inside the fixed cylinder 202. A drive motor 205 is installed inside the installation groove 204, and the grinding block 206 is installed at the output end of the drive motor 205.

[0036] Specifically, grinding blocks 203 are provided inside the main body cylinder 201 and on the outer wall of the grinding rotating block 206. A flow divider block 208 is provided on the top of the grinding rotating block 206, and a flow divider hole 207 is provided inside the main body cylinder 201.

[0037] Specifically, the fixed cylinder 202 is provided with a push block 209 inside, an adjusting push plate 210 inside, an elastic connecting plate 211 on the outer wall of the adjusting push plate 210, a pushing arc plate 212 at one end of the elastic connecting plate 211, and an adjusting groove 220 inside the fixed cylinder 202.

[0038] Specifically, the outer wall of the pushing arc plate 212 is slidably connected to the inner wall of the adjusting groove 220, the outer wall of the pushing arc plate 212 is slidably connected to the outer wall of the pushing block 209, a fixed support plate 213 is provided at one end of the pushing arc plate 212, and an anti-slip soft pad 214 is provided on the outer wall of the fixed support plate 213.

[0039] Specifically, the fixed cylinder 202 is provided with an adjusting screw 216 inside, the adjusting push plate 210 is provided with a threaded sleeve 215 inside, the outer wall of the adjusting screw 216 is threadedly connected to the inner wall of the threaded sleeve 215, and an adjusting block 217 is provided at one end of the adjusting screw 216.

[0040] Specifically, a limiting rotating seat 219 is provided inside the fixed cylinder 202, and a limiting rotating plate 218 is provided at the other end of the adjusting screw 216. The limiting rotating plate 218 is rotatably sleeved inside the limiting rotating seat 219.

[0041] Specifically, a sealing baffle 221 is provided on the top of the main tube 201, and the outer wall of the sealing baffle 221 is in contact with the inside of the pipe 3.

[0042] Example 1: In this example, to solve the problem of powder agglomeration due to absorbing moisture from the air, which affects the production efficiency, the technical solution of this implementation is as follows (see reference). Figures 1 to 6 The drive motor 205 is model 80ST-07320. The grinding blocks 203 are arranged in a linear array on the outer wall of the grinding rotor 206 and the inner wall of the main cylinder 201, and are staggered. The diverting block 208 is conical in shape. When conveying powder, the agglomerated powder enters between the grinding rotor 206 and the main cylinder 201. Then, by controlling the drive motor 205, the grinding rotor 206 is driven to rotate inside the main cylinder 201. The grinding blocks 203 arranged on the inner wall of the main cylinder 201 and the outer wall of the grinding rotor 206 can grind and crush the agglomerated powder, avoiding the blockage of the pipe 3 by the agglomerated powder and affecting the production efficiency. At the same time, it can also avoid the agglomerated powder from damaging the equipment.

[0043] It should be noted that the sealing baffle 221 is circular in shape and made of rubber. The outer wall of the sealing baffle 221 is in contact with the inner wall of the pipe 3. When conveying powder, it can accurately convey the powder between the grinding rotor 206 and the main cylinder 201 so as to grind and crush the agglomerated powder.

[0044] Example 2: In this example, to solve the problem of difficulty in breaking up agglomerated powder transported inside pipes 3 of different sizes, the technical solution of this implementation is as follows, for reference... Figures 1 to 6 The pusher block 209 is triangular in shape and is arranged in a linear array inside the fixed cylinder 202. The elastic connecting plate 211 is an arc-shaped elastic curved surface structure, and the pusher arc plate 212 is an arc-shaped plate. The outer wall of the pusher arc plate 212 is slidably connected to the outside of the pusher block 209. By rotating the adjusting block 217, the adjusting screw 216 is driven to rotate. Utilizing the threaded connection between the outer wall of the adjusting screw 216 and the inner wall of the threaded sleeve 215, the adjusting push plate 210 is pushed to slide up and down inside the fixed cylinder 202, thereby driving the pusher arc plate 212 to slide on the outer wall of the pusher block 209, so that the pusher arc plate 212 moves around the elastic connecting plate 211, thereby causing the outer wall of the fixed support plate 213 to contact the inner wall of the pipe 3. Thus, the crushing mechanism 2 can be installed inside the pipe 3. Then, by adjusting the position of the fixed support plate 213, the crushing mechanism 2 can be installed inside pipes 3 of different sizes, thereby crushing the agglomerated powder transported inside pipes 3 of different sizes.

[0045] It should be noted that the anti-slip pads 214 are set on the outer wall of the fixed support plate 213 and are distributed in a linear array. The anti-slip pads 214 are made of rubber. When the fixed support plate 213 is used to fix the crushing mechanism 2, the anti-slip pads 214 can increase the friction between the fixed support plate 213 and the inner wall of the pipe 3, so as to fix the crushing mechanism 2 to the inside of the pipe 3.

[0046] Based on the above embodiments, it can be concluded that when feeding powder raw materials in a closed manner, rotating the adjusting block 217 drives the adjusting screw 216 to rotate. Utilizing the threaded connection between the outer wall of the adjusting screw 216 and the inner wall of the threaded sleeve 215, the adjusting push plate 210 is pushed to slide up and down inside the fixed cylinder 202, thereby driving the pushing arc plate 212 to slide on the outer wall of the pushing block 209. This causes the pushing arc plate 212 to move around the elastic connecting plate 211, thereby bringing the outer wall of the fixed support plate 213 into contact with the inner wall of the pipe 3. This allows the crushing mechanism 2 to be installed inside the pipe 3. Then, by controlling the drive motor 205, the grinding block 206 is driven to rotate inside the main cylinder 201. The grinding blocks 203 set on the inner wall of the main cylinder 201 and the outer wall of the grinding block 206 can grind and crush the agglomerated powder, preventing the agglomerated powder from clogging the pipe 3 and affecting production efficiency. At the same time, it can also prevent the agglomerated powder from damaging the equipment.
