Description

Technical Field

[0001] The present invention relates to the technical field of hazardous waste recycling, and in particular to a pretreatment stirring system for hazardous waste recycling. Background Art

[0002] With the development of industry, hazardous waste will be discharged during industrial production. Existing hazardous waste needs to be evenly mixed by pre-treatment mixing equipment before recycling and processing. During pre-treatment mixing, some liquid raw materials are generally evenly mixed. The common method is to use an air compressor to blow air into the mixing box, and the liquid raw materials inside the mixing box are impacted and stirred by the impact force of the high-pressure gas. During the impact of the air compressor, the impact range is limited. As the distance increases, the impact stirring effect becomes worse. Therefore, the compressed gas blown out by the air compressor only has the best impact stirring effect on the liquid raw materials close to the blowing point. The impact stirring effect of liquid raw materials at other positions is poor, resulting in poor overall pre-stirring effect of the pre-treatment mixing raw materials, reducing the use value of the pre-treatment mixing equipment. Summary of the Invention

[0012] Preferably, a collection frame is placed on the top outer wall of the bottom plate, and the collection frame is located below the pre-mixing box. The outer wall of the collection frame is fixedly connected to fixed plates at equal distances, and the top outer wall of each fixed plate is fixedly connected to a lifting hydraulic cylinder, and the top outer wall of each lifting hydraulic cylinder is fixedly connected to a lifting frame.

[0013] Preferably, the bottom outer walls of each two adjacent lifting frames are fixedly connected to the same side splicing sieve plate, and the outer walls on the opposite sides of the two side splicing sieve plates are fixedly connected to an inverted triangular sieve plate, and the outer walls on the opposite sides of the two inverted triangular sieve plates are fixedly connected to the same middle splicing sieve plate.

[0014] The beneficial effects of the present invention are:

[0015] 1. An air compressor, a triangular air blast plate, an extrusion rack, a cylinder and a convection partition plate are provided. After the air compressor is started to blow compressed air into the triangular air blast plate, the compressed air is blown out through the air holes on the triangular air blast plate, and the liquid raw materials near the triangular air blast plate are impacted and stirred to make them evenly mixed. During the operation of the air compressor, the cylinder is started regularly to drive the extrusion rack to extrude downward, and the convection partition plate squeezes the liquid raw materials from the middle of the pre-mixing box to both ends. The direction of the compressed air blown out of the triangular air blast plate is an outward-facing eight-shaped guide, and the extrusion rack guides the liquid raw materials that have not been impacted and stirred in the middle of the triangular air blast plate into the air holes at both ends of the triangular air blast plate, so that the liquid raw materials that were originally impacted and stirred enter the air holes at both ends of the triangular air blast plate. The impact-stirred liquid raw materials roll upward along both sides of the pre-mixing tank, thereby filling the blank space created by the extrusion rack and the convection partition plate, so that the liquid raw materials inside the pre-mixing tank are circulated in a large circulation from the middle to both ends, so that the compressed gas from the air compressor impacts and stirs different liquid raw materials, thereby improving the overall stirring effect and making the liquid raw materials evenly mixed. When the extrusion rack extrude the liquid raw materials, the impact force between the extrusion rack and the liquid raw materials drives the spin axis to rotate, thereby driving the stirring blades and cutting blades between the convection partition plate and the extrusion rack to stir and cut the liquid raw materials, thereby further improving the stirring uniformity and pre-stirring effect.

[0016] 2. By providing a cutting impact block, a slice, an impact head and a shaking spring rod, the liquid raw material located in the oblique upward direction of the triangular air blowing plate is passively flipped upward, and the liquid raw material hits the cutting impact block, and the cutting impact block diverts it. At the same time, the liquid raw material drives the shaking spring rod to shake, so that the impact head performs irregular impact on the liquid raw material, and the slices evenly distributed on the impact head perform irregular cutting and stirring on the liquid raw material, thereby playing an auxiliary stirring effect, reducing the working time of the air compressor, and improving the mixing effect and mixing efficiency of the liquid raw materials of hazardous waste products.

[0017] 3. By providing a feed hopper, a feed barrel, an intermediate blocking column and a spiral discharge blade, when adding liquid raw materials, they are introduced into the spiral discharge blade through the feed hopper. The intermediate blocking column and the outer feed barrel limit the discharge route of the liquid raw materials, so that the liquid raw materials can only pass through the spiral discharge blades, thereby extending the time that the liquid raw materials are in the spiral discharge blades. The liquid raw materials repeatedly rotate and collide in the spiral discharge blades, which has the effect of preliminary stirring and mixing, thereby further improving the pre-stirring effect of the pre-stirring equipment.

[0018] 4. By providing an air pressure regulating plate, a pressure spring rod and a side frame, compressed gas is blown into the pre-mixing box through an air compressor. As the amount of compressed gas inside the pre-mixing box increases, the pressure inside the pre-mixing box increases, posing a safety hazard. Here, the air pressure regulating plate and the pressure spring rod cooperate with each other. When the pressure inside the pre-mixing box reaches a certain height, the gas impacts the air pressure regulating plate, causing the pressure spring rod to be stretched, and the air pressure regulating plate then deflects at an angle on the outer wall of the pre-mixing box, completing the air pressure regulation inside the pre-mixing box. When the air pressure inside the pre-mixing box drops to a certain value, the pressure spring rod contracts, and the air pressure regulating plate resets, thereby realizing self-regulation of the gas inside the pre-mixing box and eliminating safety hazards during the pre-mixing process.

[0019] 5. By providing an inverted triangular sieve plate, a side spliced sieve plate and a middle spliced sieve plate, when the pre-mixing of the hazardous waste product raw materials is completed, the hazardous waste product raw materials are introduced into the collection frame below through the discharge door. During the introduction process, the liquid raw materials first contact the inverted triangular sieve plate below, and the inverted triangular sieve plate performs preliminary screening on the liquid raw materials. During the screening process, the liquid raw materials slide on the outer walls on both sides of the inverted triangular sieve plate due to gravity factors, avoiding clogging of the sieve holes of the inverted triangular sieve plate. After the preliminary screening, the liquid raw materials enter the side spliced sieve plate and the middle spliced sieve plate, thereby completing the secondary screening operation. After the overall screening is completed, the jacking hydraulic cylinder is adjusted to drive the side spliced sieve plate, the inverted triangular sieve plate and the middle spliced sieve plate to rise, thereby facilitating the rapid collection of pre-mixed liquid raw materials of different specifications and improving the overall process progress.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

By providing the air compressor 7, the triangular air blowing plate 13, the extrusion frame 18, the cylinder 17 and the convection partition plate 19, after starting the air compressor 7 to blow compressed gas into the triangular air blowing plate 13, the compressed gas passes through the triangular air blowing plate 13 The air holes 20 on the triangular air blast plate 13 blast out the compressed gas to impact and stir the liquid raw materials near the triangular air blast plate 13 to make them evenly mixed. During the operation of the air compressor 7, the cylinder 17 is started regularly to drive the extrusion rack 18 to extrude downward, and the convection partition plate 19 squeezes the liquid raw materials from the middle of the pre-mixing box 6 to both ends. The compressed gas blasted out from the triangular air blast plate 13 is guided in an outward-facing eight-shaped direction. The extrusion rack 18 pushes the liquid raw materials that have not been impacted and stirred in the middle of the triangular air blast plate 13 into the air holes 20 at both ends of the triangular air blast plate 13, so that the liquid raw materials that have been impacted and stirred originally roll upward along both sides of the pre-mixing box 6, thereby filling the liquid raw materials that have been impacted and stirred. The blank space created by the squeezing of the pressing frame 18 and the convection partition plate 19 causes the liquid raw materials inside the pre-mixing box 6 to operate in a large circulation manner from the middle to the two ends, so that the compressed gas blown out by the air compressor 7 impacts and stirs the different liquid raw materials, thereby improving the overall stirring effect and making the liquid raw materials evenly mixed. When the extrusion frame 18 extrude the liquid raw materials, the impact force between the extrusion frame 18 and the liquid raw materials drives the spin shaft 21 to rotate, thereby driving the stirring blades 24 and the cutting blades 22 between the convection partition plate 19 and the extrusion frame 18 to stir and cut the liquid raw materials, thereby further improving the stirring uniformity and pre-mixing effect.

By providing the cutting and impacting blocks 25, slices 26, impacting heads 27 and shaking spring rods 28, the liquid raw material located in the oblique upward direction of the triangular air blowing plate 13 is passively turned upward. The liquid raw material hits the cutting and impacting blocks 25, and the cutting and impacting blocks 25 divert it. The liquid raw material drives the shaking spring rods 28 to shake, so that the impact head 27 performs irregular impact on the liquid raw material, and the slices 26 evenly distributed on the impact head 27 perform irregular cutting and stirring on the liquid raw material, thereby playing an auxiliary stirring effect, reducing the working time of the air compressor 7, and improving the mixing effect and mixing efficiency of the liquid raw materials of hazardous waste products.

[0032] Reference Figure 1 The outer walls on both sides of the pre-mixing box 6 are fixedly connected to two support frames 2, and the bottom outer walls of the four support frames 2 are fixedly connected to a support seat 9, which is located above the bottom plate 1.

[0033] Reference Figure 1 and Figure 6 The top outer wall of the pre-mixing box 6 is fixedly connected to two feed plates 4, and the two feed plates 4 are in contact with the top plate 16. The top outer walls of the two feed plates 4 are each provided with two feed holes. The inner wall of each feed hole is fixedly connected to a feed barrel 12, and the top outer wall of the feed barrel 12 is fixedly connected to a feed hopper 5, and the inner wall of the feed barrel 12 is fixedly connected to a spiral discharge blade 29. The spiral discharge blade 29 is located in the middle of the outer wall and is fixedly connected to an intermediate blocking column 30. By arranging the feed hopper 5, the feed barrel 12, and the intermediate blocking column 30 and the spiral discharge blade 29, when adding liquid raw materials, they are introduced into the spiral discharge blade 29 through the feed hopper 5, and the middle blocking column 30 and the outer feed cylinder 12 limit the discharge route of the liquid raw materials, so that the liquid raw materials can only pass through the spiral discharge blade 29, thereby extending the time the liquid raw materials are in the spiral discharge blade 29. The liquid raw materials repeatedly rotate and collide in the spiral discharge blade 29, which has the effect of preliminary stirring and mixing, thereby further improving the pre-stirring effect of the pre-stirring equipment.

[0034] Reference Figure 2 Both ends of the bottom outer wall of the pre-mixing box 6 are provided with discharge holes, and the inner walls of the two discharge holes are connected with discharge doors 15 through hinges.

[0035] Reference Figure 1 and Figure 7, the outer walls on both sides of the pre-mixing box 6 are connected to the air pressure regulating plates 3 through hinges, and the outer walls on both sides of the pre-mixing box 6 near the two air pressure regulating plates 3 are fixedly connected to two side frames 31, the side frames 31 and the outer walls of the air pressure regulating plates 3 are fixedly connected to fixed blocks 33, and the outer walls on the opposite sides of each corresponding two fixed blocks 33 are fixedly connected to the same pressure spring rod 32. By providing the air pressure regulating plates 3, the pressure spring rod 32 and the side frames 31, compressed gas is blown into the pre-mixing box 6 through the air compressor 7. As the amount of compressed gas inside the pre-mixing box 6 increases, the pre-mixing box 6, the pressure inside increases, there is a safety hazard, here through the cooperation of the air pressure regulating plate 3 and the pressure spring rod 32, when the pressure inside the pre-mixing box 6 reaches a certain height, the gas impacts the air pressure regulating plate 3, so that the pressure spring rod 32 is stretched, and the air pressure regulating plate 3 is then deflected at an angle on the outer wall of the pre-mixing box 6, completing the air pressure regulation inside the pre-mixing box 6, when the air pressure inside the pre-mixing box 6 drops to a certain value, the pressure spring rod 32 contracts, and the air pressure regulating plate 3 is reset, so that the gas inside the pre-mixing box 6 can be self-regulated, eliminating the safety hazard during the pre-mixing process.

[0036] Reference Figure 1 and Figure 8 , a collecting frame 11 is placed on the top outer wall of the bottom plate 1, and the collecting frame 11 is located below the pre-mixing box 6, and the outer wall of the collecting frame 11 is fixedly connected with fixed plates 37 at equal distances, and the top outer wall of each fixed plate 37 is fixedly connected with a lifting hydraulic cylinder 14, and the top outer wall of each lifting hydraulic cylinder 14 is fixedly connected with a lifting frame 34, and the bottom outer wall of each adjacent two lifting frames 34 is fixedly connected with the same side spliced sieve plate 36, and the outer walls of the opposite sides of the two side spliced sieve plates 36 are fixedly connected with an inverted triangular sieve plate 10, and the outer walls of the opposite sides of the two inverted triangular sieve plates 10 are fixedly connected with the same middle spliced sieve plate 35. By providing the inverted triangular sieve plate 10, the side spliced sieve plate 36 and the middle spliced sieve plate 35, when the pre-mixing of the raw materials of hazardous waste products is completed, The hazardous waste product raw materials are introduced into the collection frame 11 below through the unloading door 15. During the introduction process, the liquid raw materials first contact the inverted triangular sieve plate 10 below, and the inverted triangular sieve plate 10 performs preliminary screening on the liquid raw materials. During the screening process, the liquid raw materials slide on the outer walls on both sides of the inverted triangular sieve plate 10 due to gravity factors, avoiding clogging of the sieve holes of the inverted triangular sieve plate 10. After the preliminary screening, the liquid raw materials enter the side splicing sieve plate 36 and the middle splicing sieve plate 35, thereby completing the secondary screening operation. After the overall screening is completed, the lifting hydraulic cylinder 14 is adjusted to drive the side splicing sieve plate 36, the inverted triangular sieve plate 10 and the middle splicing sieve plate 35 to rise, thereby facilitating the rapid collection of pre-stirred liquid raw materials of different specifications and improving the overall process progress.

[0037] During use, first pour the liquid raw material into each feed hopper 5, and then enter the spiral discharge blade 29 in the feed barrel 12 along the feed hopper 5. The middle blocking column 30 and the outer feed barrel 12 limit the discharge route of the liquid raw material, so that the liquid raw material can only pass through the spiral discharge blade 29, thereby extending the time the liquid raw material is in the spiral discharge blade 29. The liquid raw material repeatedly rotates and collides in the spiral discharge blade 29, which has the effect of preliminary stirring and mixing. After preliminary stirring, the liquid raw material falls into the pre-mixing box 6 below.

Impact stirring to make it evenly mixed. During the operation of the air compressor 7, the cylinder 17 is started regularly to drive the extrusion frame 18 to squeeze downward, and the convection partition plate 19 squeezes the liquid raw materials from the middle of the pre-mixing box 6 to both ends. The compressed gas bulged out from the triangular air blowing plate 13 is guided in an outward-facing eight-shaped direction. The extrusion frame 18 drives the liquid raw materials that have not been impact-stirred in the middle of the triangular air blowing plate 13 into the air holes 20 at both ends of the triangular air blowing plate 13, so that the liquid raw materials that have been impact-stirred originally roll upward along both sides of the pre-mixing box 6, thereby filling the blank space squeezed by the extrusion frame 18 and the convection partition plate 19, so that the liquid raw materials inside the pre-mixing box 6 operate in a large circulation from the middle to the two ends, so that the air compressor 7 bulges out. The compressed gas impacts and stirs different liquid raw materials, thereby improving the overall stirring effect and making the liquid raw materials evenly mixed. When the extrusion frame 18 extrudes the liquid raw materials, the impact force between the extrusion frame 18 and the liquid raw materials drives the spin shaft 21 to rotate, thereby driving the stirring blades 24 and the cutting blades 22 between the convection partition plate 19 and the extrusion frame 18 to stir and cut the liquid raw materials. At the same time, when the upward rolling liquid raw materials pass through the cutting and impacting block 25, the cutting and impacting block 25 diverts them, and the liquid raw materials drive the shaking spring rod 28 to shake, so that the impact head 27 performs irregular impact on the liquid raw materials, and the slices 26 evenly distributed on the impact head 27 perform irregular cutting and stirring on the liquid raw materials. Thereby, it has the effect of assisting stirring. After the pre-stirring is completed, the discharge door 15 is opened, and the pre-stirred liquid raw materials fall onto the inverted triangular sieve plate 10 below. The inverted triangular sieve plate 10 performs preliminary screening on the liquid raw materials. During the screening process, the liquid raw materials slide on the outer walls on both sides of the inverted triangular sieve plate 10 due to gravity factors, avoiding clogging of the sieve holes of the inverted triangular sieve plate 10. After the preliminary screening, the liquid raw materials enter the side splicing sieve plate 36 and the middle splicing sieve plate 35, thereby completing the secondary screening operation. After the overall screening is completed, the lifting hydraulic cylinder 14 is adjusted to drive the side splicing sieve plate 36, the inverted triangular sieve plate 10 and the middle splicing sieve plate 35 to rise, thereby facilitating the rapid collection of pre-stirred liquid raw materials of different specifications and ending the operation.
