Description

Technical Field

[0002] Sludge treatment: A process of reducing the quantity, stabilizing, and rendering harmless of sludge through concentration, conditioning, dehydration, stabilization, drying, or incineration, etc.

[0003] For the current sludge drying and dehydration device, it needs to be stirred before the drying work, and a dehydrating agent is added during the stirring process so that the sludge can be better dried during the drying process. However, for the current stirring device, the stirring is often uneven, and since the stirring rod is fixed at a certain position, the dehydrating agent cannot be evenly mixed in the sludge. Therefore, we propose a rapid sludge dehydration device based on environmental protection. Summary of the Invention

[0021] Furthermore, air holes are provided at the upper and lower ends on the left side inside the arc-shaped box body. The number of the air holes is four. Check valves three are fixedly connected to the right sides inside the four air holes.

[0022] The present invention has the following beneficial effects:

[0023] In the present invention, through the cylindrical block, when the two cylindrical rods rotate, the sludge will be stirred through the fixing plate, and the square block one and the square block two will be struck through the circular block. The helically arranged fixing plate maximally avoids the uneven mixing caused by the traditional fixed stirring rod, and also indirectly increases the mixing efficiency. Through the circular shape of the circular block, it is ensured that the phenomenon that the circular block is stuck with the square block one or the square block two will not occur. Through the circular partition plate, it is possible to prevent the sludge from flowing into the fixed block one and affecting the normal operation of the large gear.

[0024] In the present invention, through the first square block, when the first square block is stressed, it drives the first fixed clamping rod to move leftward inside the second chute. When the first fixed clamping rod moves, it not only squeezes the air inside the second chute but also squeezes the first spring. When the first square block is not stressed, the first spring will push out the first fixed clamping rod, and due to the negative pressure effect, the external air is inhaled into the second chute through the air inlet groove. Since the first air pipe, the first right-angle air pipe, the second right-angle air pipe, and the second air pipe transport the air in the second chute to the inside of the third chute, the square push block is pushed out slowly to the outside by the air pressure through the first fixed rod, reducing the space inside the cylindrical block, thereby achieving the effect of squeezing the sludge, increasing the mixing effect to a certain extent, and the first square block itself can also achieve the effect of squeezing the sludge through the first fixed clamping rod.

[0025] In the present invention, through the second square block, when the second square block is stressed, it drives the two second fixed clamping rods to move leftward and squeezes the air inside the groove, which enters the inside of the arc-shaped box body through the second one-way valve. Since the air entering the inside of the arc-shaped box body cannot flow out, it will remain in the arc-shaped box body. When the air inside the arc-shaped box body accumulates to a certain extent, it will exert pressure on the dehydrating agent inside, causing it to flow out through the third one-way valve at the bottom left of the arc-shaped box body into the cylindrical block, thereby achieving the effect of automatically adding the dehydrating agent, saving the time for the staff to watch and manually supplement the dehydrating agent, enabling the staff to do more things in the same original time, and greatly improving the work efficiency.

[0026] In the present invention, through the connecting block, the fixing effect between the two cylindrical blocks can be improved, and the situation of shaking during the rotation work can be avoided. Through the first one-way valve, when the first fixed clamping rod pushes the air, the air leakage from the air inlet groove is avoided. Through the second one-way valve, when the second fixed clamping rod pushes the air, the air leakage from the air hole is avoided. Through the third one-way valve, the sludge inside the cylindrical block is prevented from entering the arc-shaped box body.

[0027] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Please refer to Figures 1-7As shown in the figure, the present invention is a rapid sludge dewatering device based on environmental protection, including a power mechanism 1. On the left and right sides of the top of the power mechanism 1, there are cylindrical blocks 2. At one end where the two cylindrical blocks 2 are close to each other, there is a connecting block 3 fixedly installed. At one end where the two cylindrical blocks 2 are away from each other, there is an arc-shaped box body 4 fixedly installed. At the upper and lower ends on the side where the two cylindrical blocks 2 are away from each other, there are arc-shaped pipes 5;

[0041] At the inner opening of each of the four arc-shaped pipes 5, there is a plug 51. At one end where the four arc-shaped pipes 5 are close to each other, there is a square connecting block 52 fixedly connected. At one end where the four square connecting blocks 52 are close to each other, they are fixedly connected to the left and right sides of the two cylindrical blocks 2.

[0042] The inside of the power mechanism 1 includes a first fixed block 11, a protection box 12, a motor 13, a rotating rod 14, a small gear 15, and a large gear 16. The protection box 12 is fixedly installed at the central axis of the bottom of the first fixed block 11. The motor 13 is fixedly installed inside the protection box 12. The rotating rod 14 is rotatably connected to the top output end of the motor 13. The top of the rotating rod 14 is rotatably connected to the inner top wall of the first fixed block 11 through a bearing. The small gear 15 is arranged on the outer surface of the rotating rod 14, and the large gears 16 are arranged on the left and right sides of the small gear 15;

[0043] The small gear 15 meshes with the two large gears 16. The two large gears 16 are rotationally connected to the motor 13 through the small gear 15 and the rotating rod 14.

[0044] On the top of each of the two arc-shaped box bodies 4, there is a plug block. The shapes of the two plug blocks are both cylindrical. At the lower end of the left side inside the arc-shaped box body 4, there is a check valve three installed. Through the check valve three, it is avoided that the sludge inside the cylindrical block 2 enters the arc-shaped box body 4.

[0045] The inside of the cylindrical block 2 includes a circular partition 21, a cylindrical rod 22, a first square block 23, a pushing block 24, a blocking block 25, and a second square block 26. The circular partition 21 is fixedly installed at the bottom inner wall of the cylindrical block 2. Through the circular partition 21, it can be avoided that the sludge flows into the first fixed block 11 and affects the normal operation of the large gear 16. The cylindrical rod 22 is arranged at the central axis inside the cylindrical block 2. At the upper and lower ends of the left inner wall of the cylindrical block 2, there are first square grooves. The first square blocks 23 are slidably connected inside the two first square grooves. Below the two first square grooves, there are second square grooves. The pushing blocks 24 are slidably connected inside the two second square grooves. The blocking blocks 25 are fixedly installed on the left sides of the two pushing blocks 24. At the upper and lower ends of the right side of the cylindrical block 2, there are third square grooves. The second square blocks 26 are slidably connected inside the two third square grooves. Through the cylindrical block 2, when the two cylindrical rods 22 rotate, they will stir the sludge through the fixing plate 221, and strike the first square block 23 and the second square block 26 through the circular block 223. The helically arranged fixing plate 221 maximally avoids the uneven mixing situation caused by the traditional fixed stirring rod, and also increases the mixing efficiency in disguise;

[0046] The bottom of the cylindrical rod 22 penetrates through the circular partition plate 21 and the top of the first fixed block 11 and extends to the inside. The outer surface of the lower end of the cylindrical rod 22 is fixedly connected to the large gear 16, and the top of the cylindrical rod 22 is rotationally connected to the top inner wall of the cylindrical block 2 through a bearing.

[0047] The outer surface of the cylindrical rod 22 is spirally provided with a fixing plate 221. The upper and lower ends of the left and right sides of the cylindrical rod 22 are fixedly connected with connecting rods 222. The mutually remote ends of the four connecting rods 222 are all fixedly connected with circular blocks 223. Due to the circular shape of the circular blocks 223, the phenomenon that the circular blocks 223 are stuck with the first square block 23 or the second square block 26 is avoided.

[0048] The mutually remote ends of the four circular blocks 223 are respectively in contact with the mutually approaching ends of the two first square blocks 23 and the two second square blocks 26.

[0049] The upper and lower ends of the inner wall of the first square groove are both provided with first sliding grooves. The upper and lower ends of the first square block 23 are fixedly connected with sliding blocks 231. The upper and lower ends of the left side of the inner wall of the first square groove are both provided with second sliding grooves. The upper and lower ends of the left side of the first square block 23 are fixedly connected with first fixed clamping rods 232. An air inlet groove 233 is opened at the central axis of the left side of the inner wall of the first square groove. Through the first square block 23, when the first square block 23 is stressed, it drives the first fixed clamping rod 232 to move leftward inside the second sliding groove. When the first fixed clamping rod 232 moves, it not only squeezes the air inside the second sliding groove but also squeezes the first spring. When the first square block 23 is not stressed, the first spring will push out the first fixed clamping rod 232, and through the negative pressure effect, the external air is sucked into the second sliding groove through the air inlet groove 233. Since the first air pipe 31, the first right-angle air pipe 32, the second right-angle air pipe 33, and the second air pipe 34 convey the air in the second sliding groove to the inside of the third sliding groove, the square push block 35 is pushed by the air pressure and slowly pushes the push block 24 out to the outside through the first fixed rod 36, making the space inside the cylindrical block 2 smaller, thereby achieving the effect of squeezing the sludge to a certain extent and increasing the mixing effect. Moreover, the first square block 23 itself can also achieve the effect of squeezing the sludge through the first fixed clamping rod 232;

[0050] One-way valves 1 are fixedly installed at the upper and lower ends inside the air inlet groove 233. The two first fixed clamping rods 232 are both slidably connected inside the two second sliding grooves. Through the one-way valves 1, it is avoided that when the first fixed clamping rod 232 pushes the air, the air will flow out from the air inlet groove 233.

[0051] The inside of the connecting block 3 includes an air pipe 31, a right-angled air pipe 32, a right-angled air pipe 33, an air pipe 34, a square push block 35, a fixing rod 36 and an air outlet 37. The air pipe 31 is fixedly connected to the left side inside the two sliding grooves 2. The right-angled air pipe 32 is fixedly connected to the left side of the two air pipes 31. The right-angled air pipe 33 is fixedly connected to the bottom of the right-angled air pipe 32. The air pipe 34 is fixedly connected to the bottom of the right-angled air pipe 33. Sliding grooves 3 are provided on the right side of the right-angled air pipe 33 and the left side of the air pipe 34. The square push blocks 35 are all slidably connected inside the two sliding grooves 3. The fixing rods 36 are fixedly connected to the ends of the two square push blocks 35 away from the right-angled air pipe 33 and the air pipe 34. The air outlets 37 are provided at one end where the two sliding grooves 3 are close to each other. Through the connecting block 3, the fixing effect between the two cylindrical blocks 2 can be improved, and it is also avoided that they will shake during the rotation operation;

[0052] The right side of the fixing rod 36 at the top is fixedly connected to the push block 24 at the top.

[0053] Grooves are provided at the upper and lower ends on the right side of the inner wall of the square groove 3. Fixing clamping rods 261 are fixedly connected to the upper and lower ends on the left side of the square block 26;

[0054] The right sides of the two fixing clamping rods 261 are all slidably connected inside the two grooves. Suction holes 262 are provided at the upper and lower ends on the right side inside the two grooves. Check valves 2 are fixedly installed inside the four suction holes 262. Through the check valve 2, it is avoided that when the fixing clamping rod 261 pushes air, air will flow out from the suction hole 262. Through the square block 26, when the square block 26 is under pressure, it will drive the two fixing clamping rods 261 to move to the left and squeeze the air inside the groove to enter the arc-shaped box body 4 through the check valve 2. Since the air entering the arc-shaped box body 4 cannot flow out, it will stay in the arc-shaped box body 4. When the air inside the arc-shaped box body 4 accumulates to a certain extent, it will exert pressure on the dehydrating agent inside, causing it to flow out through the check valve 3 at the bottom left of the arc-shaped box body 4 into the cylindrical block 2, thus achieving the effect of automatically adding the dehydrating agent, subtracting the time required for the staff to watch and manually supplement the dehydrating agent, enabling the staff to do more things in the same original time, and greatly improving the work efficiency.

[0055] Air holes are provided at the upper and lower ends on the left side inside the arc-shaped box body 4. The number of air holes is four. Check valves 3 are fixedly connected to the right side inside the four air holes.

[0056] A specific application of this embodiment is as follows: The sludge to be stirred is respectively injected into the two cylindrical blocks 2 from the arc-shaped pipes 5 on both sides of the top. Then, the motor 13 is started, and the small gear 15 rotates driven by the rotating rod 14. The large gears 16 on both sides are driven by the small gear 15 to drive the two cylindrical rods 22 to rotate. When the two cylindrical rods 22 rotate, they will stir the sludge through the fixing plate 221, and strike the first square block 23 and the second square block 26 through the circular block 223. When the first square block 23 is stressed, it drives the first fixed clamping rod 232 to move to the left inside the second chute. When the first fixed clamping rod 232 moves, it will squeeze the air inside the second chute and also squeeze the first spring. When the first square block 23 is not stressed, the first spring will push out the first fixed clamping rod 232, and suck the external air into the second chute through the air intake groove 233 by the effect of negative pressure. Since the first air pipe 31, the first right-angle air pipe 32, the second right-angle air pipe 33 and the second air pipe 34 transport the air in the second chute to the inside of the third chute, the square push block 35 is pushed by the air pressure to slowly push the push block 24 out to the outside through the first fixed rod 36, reducing the space inside the cylindrical block 2, thereby achieving the effect of squeezing the sludge and increasing the mixing effect to a certain extent. When the second square block 26 is stressed, it drives the two second fixed clamping rods 261 to move to the left and squeeze the air inside the groove, which enters the arc-shaped box body 4 through the second one-way valve. Since the air entering the arc-shaped box body 4 cannot flow out, it will remain in the arc-shaped box body 4. When the air in the arc-shaped box body 4 accumulates to a certain extent, it will apply pressure to the dehydrating agent inside, causing it to flow out to the cylindrical block 2 through the third one-way valve at the bottom left of the arc-shaped box body 4, thus achieving the effect of automatically adding the dehydrating agent. When the sludge needs to be taken out, the plug blocks 51 in the arc-shaped pipes 5 on the left and right sides of the two cylindrical blocks 2 are taken out, and then the sludge will flow out automatically.
