Description

Technical Field

[0001] The invention relates to the technical field of chemical sludge drying, and in particular to a chemical sludge drying treatment device. Background Art

[0002] The chemical sludge drying treatment device includes multiple units, among which the snail stacker is one of the key components. The snail stacker removes water from the sludge by mechanical pressing. When the snail stacker treats the sludge, it first adds flocculants to the mud water. After the flocculants are added, the mud water enters the flocculation reaction zone. The flocculants react with the suspended matter in the sludge to form flocs, creating conditions for the subsequent dehydration steps. The flocculated sludge is sent to the snail stacker's concentration and dehydration bin for dehydration and drying.

[0003] Referring to the Chinese patent document with the announcement number CN217265379U and the announcement date of August 23, 2022, the name is a small integrated snail stacking machine, which includes a flocculation and conditioning bin and a dosing bin. The sludge is placed in the dosing bin and the agent is added. The sludge then enters the flocculation and conditioning bin for stirring and flocculation, and then is transported to the sludge concentration and dehydration bin of the snail stacking machine for dehydration treatment.

[0004] However, organic matter, clay minerals or grease in the sludge tend to form sticky flocs during the flocculation process, which may adhere to the inner wall of the tank and affect the flow of the sludge. Some flocs may settle at the bottom of the tank to form a sediment layer, which not only reduces the effective volume of the tank, but also may cause poor sludge flow.

[0005] The above-mentioned adhesion and deposition problems will reduce the fluidity of the sludge in the tank and affect the sludge drying efficiency of the device. In order to maintain the normal operation of the equipment, the inner wall and bottom of the tank need to be cleaned more frequently, which increases maintenance costs and downtime. Summary of the invention

[0006] In view of this, the present invention provides a chemical sludge drying treatment device, aiming to solve the technical problem of low drying treatment efficiency caused by sludge adhesion and deposition in the prior art.

[0007] In order to solve the above technical problems, the chemical sludge drying treatment device provided by the present invention adopts the following technical scheme: the chemical sludge drying treatment device comprises a flocculation tank body assembled on a spiral stacking machine body; a cleaning rack vertically slidably connected to the inner wall of the flocculation tank body, the cleaning rack comprises a plurality of vertically arranged cleaning rods, the cleaning rods abut against the inner wall of the flocculation tank body, a moving rod is connected to the cleaning rod, an internal hollow moving column is provided at the bottom of the inside of the flocculation tank body, the moving rod is vertically slidably connected to the inner wall of the moving column, a plurality of interconnected air pipes are provided at the bottom of the outside of the flocculation tank body, the air pipes can supply air through an external air supply structure, the air pipes are connected to the bottom of the moving column, a plurality of air outlets connected to the bottom of the internal cavity of the flocculation tank body are opened on the air pipe, and a one-way valve is provided at the air outlet.

[0008] By adopting the above technical solution, the vertical reciprocating movement of the cleaning frame can scrape off the sludge adhered to the inner wall of the flocculation tank, reduce the accumulation of sludge on the inner wall of the flocculation tank, and by cleaning the inner wall, the sludge flow in the flocculation tank can be kept unobstructed, the flow resistance can be reduced, the processing efficiency can be improved, the shutdown cleaning and maintenance cycle of the flocculation tank can be extended, the downtime can be reduced, and the continuous operation capacity of the equipment can be improved.

[0009] The air pipe blows air to the bottom of the flocculation tank through the air outlet. The air blowing can disturb the sludge at the bottom of the flocculation tank and improve the formation of a sedimentation layer of the sludge at the bottom. The air blowing can also promote the flocculation process and improve the mixing effect of the sludge and the reagent in the flocculation tank.

[0010] The vertical movement of the cleaning rack is controlled by supplying air through the air pipe, and the air pipe blows air through the air outlet. This structure is relatively simple and does not require complex electric and transmission mechanisms, which reduces potential failure points and improves the reliability of the system. Due to the simple structure, maintenance is also more convenient and adaptable. By adjusting the air flow and pressure, the moving speed of the cleaning rack can be flexibly adjusted to meet different cleaning needs.

[0011] Optionally, a tilted pushing plate is connected to the top of the cleaning frame, a discharge port is provided on the left side of the flocculation tank, and the pushing plate is tilted downward from left to right.

[0012] By adopting the above technical solution, the inclined pushing plate can help guide the sludge to flow to the discharge port, ensure that the sludge moves according to the predetermined process, reduce the disordered flow of sludge in the flocculation tank, and improve the discharge efficiency.

[0013] Optionally, the bottom surface of the push plate is slidably connected to a scraper plate in the left-right direction, and a connecting rod is hinged between the scraper plate and the left side of the inner wall of the flocculation tank.

[0014] By adopting the above technical solution, during the vertical reciprocating movement of the pushing plate, under the action of the connecting rod, the scraper plate slides left and right along the bottom surface of the pushing plate, which can effectively scrape off the sludge attached to the bottom surface of the pushing plate and keep the pushing plate clean. The pushing plate and the scraper plate are linked by the connecting rod, which can improve the degree of automation of the device.

[0015] Optionally, the front, rear and right sides of the cleaning rack are connected to water pipe 1, a one-way valve is provided at the bottom of water pipe 1, water pipe 2 is provided at the top of the push plate, the top of water pipe 1 is connected to water pipe 2, a water outlet hole is provided on the bottom surface of the push plate, and water pipe 2 is connected to the water outlet hole.

[0016] By adopting the above technical solution, during the downward movement of the cleaning frame, the water flow at the bottom of the flocculation tank enters the interior of the water pipe one. As the water flow in the water pipe one increases, the water flow moves upward to the water pipe two, and is sprayed onto the sludge on the water surface inside the flocculation tank through the water outlet, thereby being able to wet the sludge floating on the water surface, solving the problem of difficult sludge flow in the flocculation tank due to sludge drying, and improving the degree of automation of the device.

[0017] Optionally, a spherical filter is provided at the bottom of the water pipe 1.

[0018] By adopting the above technical solution, the situation where sludge enters the water pipe can be reduced as much as possible, ensuring the normal operation of the structure.

[0019] Optionally, the top surface of the cleaning rod is inclined from top to bottom toward the direction close to the central axis of the flocculation tank body, and the bottom surface of the cleaning rod is inclined from bottom to top toward the direction close to the central axis of the flocculation tank body.

[0020] By adopting the above technical solution, the top and bottom surfaces of the cleaning rod are both inclined. When the cleaning rod moves back and forth vertically, the water flow has an impact on the top and bottom surfaces of the cleaning rod, which can reduce the sludge adhering to the top and bottom surfaces of the cleaning rod. At the same time, the inclined top and bottom surfaces have a guiding effect on the water flow and sludge, promoting the sludge to flow to the middle of the flocculation tank, thereby facilitating the sludge to flow upward.

[0021] Optionally, a compression spring is sleeved on the moving rod, the top end of the compression spring is connected to the top of the inner cavity of the moving column, and the bottom end of the compression spring is connected to the bottom of the moving rod.

[0022] By adopting the above technical solution, the normal operation of the device is further guaranteed, and the stability of the vertical reciprocating movement process of the cleaning rod is ensured.

[0023] Optionally, through holes are provided on the multiple cleaning rods on the left side of the cleaning frame.

[0024] By adopting the above technical solution, the resistance encountered by the cleaning rod during vertical movement can be reduced, and the mutual interference between structures can be reduced.

[0025] In summary, the present invention includes the following beneficial technical effects: 1. It can clean the sludge attached to the inner wall of the flocculation tank, improve the sludge deposition at the bottom of the cavity inside the flocculation tank, keep the sludge flow in the flocculation tank smooth, reduce flow resistance, improve treatment efficiency, extend the shutdown cleaning and maintenance cycle of the flocculation tank, promote the flocculation process, and improve the mixing effect.

[0026] 2. The inclined push plate can help guide the sludge to flow to the discharge port, ensure that the sludge moves according to the predetermined process, reduce the disordered flow of sludge in the flocculation tank, and improve the discharge efficiency.

[0027] 3. The scraper plate slides left and right along the bottom surface of the push plate, which can effectively scrape off the sludge attached to the bottom surface of the push plate and keep the push plate clean. The push plate and the scraper plate are linked by the connecting rod to improve the degree of automation of the device.

[0028] 4. Water flows through the outlet hole to the sludge on the water surface inside the flocculation tank, which can moisten the sludge floating on the water surface and solve the problem of sludge flow difficulty in the flocculation tank caused by sludge drying.

[0029] 5. The inclined top and bottom surfaces can reduce the situation where sludge adheres to the top and bottom surfaces of the cleaning rod, and at the same time guide the water flow and sludge, promote the sludge to flow to the middle of the flocculation tank, and facilitate the sludge to flow upward.

[0036] Reference Figure 2 and Figure 4The cleaning rack 3 is slidably connected to the inner wall of the flocculation tank 2, and the cleaning rack 3 reciprocates vertically. The cleaning rack 3 includes a plurality of cleaning rods 31 and a plurality of supporting rods 32, the supporting rods 32 are placed vertically, the plurality of supporting rods 32 are arranged along the circumference of the flocculation tank 2, the supporting rods 32 are used to support the cleaning rods 31, the cleaning rods 31 are placed horizontally, and the plurality of cleaning rods 31 are divided into four groups, each group of cleaning rods 31 is composed of a plurality of cleaning rods 31 arranged longitudinally, and each group of cleaning rods 31 is arranged between two adjacent supporting rods 32. The cleaning rods 31 abut against the inner wall of the flocculation tank 2, and the cleaning rods 31 can scrape off the sludge attached to the inner wall of the flocculation tank 2 during the vertical reciprocating movement of the cleaning rack 3. Reduce the accumulation of sludge on the inner wall of the flocculation tank 2, and by cleaning the inner wall, the sludge flow in the flocculation tank 2 can be kept unobstructed, the flow resistance can be reduced, the processing efficiency can be improved, the shutdown cleaning and maintenance cycle of the flocculation tank 2 can be extended, the downtime can be reduced, and the continuous operation capacity of the equipment can be improved.

[0037] Reference Figure 2 and Figure 3 Furthermore, the top surface of the cleaning rod 31 is inclined from top to bottom toward the direction close to the central axis of the flocculation tank body 2, and the bottom surface of the cleaning rod 31 is inclined from bottom to top toward the direction close to the central axis of the flocculation tank body 2. The top and bottom surfaces of the cleaning rod 31 are both inclined. When the cleaning rod 31 moves back and forth vertically, the water flow has an impact on the top and bottom surfaces of the cleaning rod 31, which can reduce the situation where sludge adheres to the top and bottom surfaces of the cleaning rod 31. At the same time, the inclined top and bottom surfaces have a guiding effect on the water flow and sludge, promoting the sludge to flow to the middle of the flocculation tank body 2, which is convenient for the sludge to flow upward.

[0038] Reference Figure 4 and Figure 5 Further, a plurality of cleaning rods 31 on the left side of the cleaning frame 3 are provided with through holes 311. The resistance received by the cleaning rods 31 during the vertical movement can be reduced.

[0039] Reference Figure 2 and Figure 3 The blowing member 4 includes a moving rod 41 , a moving column 42 , an air pipe 43 , an air outlet 44 and a compression spring 45 .

[0040] Reference Figure 3 and Figure 4There are multiple moving rods 41, which are arranged along the circumference of the flocculation tank body 2. The moving rods 41 are fixedly connected to one of the cleaning rods 31. There are multiple moving columns 42, which are arranged along the circumference of the flocculation tank body 2. The multiple moving rods 41 correspond to the multiple moving columns 42 one by one. The moving rods 41 are vertically slidably connected to the inner wall of the moving column 42. The multiple air pipes 43 are interconnected and are all arranged at the bottom outside the flocculation tank body 2. The air pipes 43 can be supplied with air through an external air supply structure. The air pipes 43 are connected to the bottom of the moving column 42. The cleaning rack 3 can be moved upward by inflating the air pipes 43.

[0041] Reference Figure 3 There are multiple air outlets 44, which are opened on the air pipe 43 and connected to the bottom of the internal cavity of the flocculation tank 2. A one-way valve is provided at the air outlet 44. When the air pipe 43 is inflated, the gas is blown to the bottom of the internal cavity of the flocculation tank 2 through the air outlet 44. Blowing can disturb the sludge at the bottom of the flocculation tank 2 and improve the formation of a sedimentation layer at the bottom. Blowing can also promote the flocculation process and improve the mixing effect of the sludge and the reagent in the flocculation tank 2.

[0042] Reference Figure 2 and Figure 3 When the air pipe 43 blows air, the cleaning rack 3 can move upward and blow air through the air outlet 44. When the air pipe 43 stops blowing air, the cleaning rack 3 moves downward under its own gravity, and the gas in the air pipe 43 is blown out through the air outlet 44. This structure is relatively simple, does not require complex electric and transmission mechanisms, reduces potential failure points, and improves the reliability of the system. Due to the simple structure, it is more convenient to maintain and has strong adaptability. By adjusting the air flow and pressure, the moving speed of the cleaning rack 3 can be flexibly adjusted to meet different cleaning needs.

[0043] Reference Figure 3 and Figure 5 Further, the blowing member 4 further includes a compression spring 45, and a plurality of compression springs 45 are provided, and the plurality of compression springs 45 correspond to the plurality of moving columns 42 one by one, and the compression spring 45 is vertically arranged inside the moving column 42, and the compression spring 45 is sleeved on the moving rod 41, and the top end of the compression spring 45 is connected to the top of the internal cavity of the moving column 42, and the bottom end of the compression spring 45 is connected to the bottom of the moving rod 41. The compression spring 45 applies a downward force to the cleaning frame 3 to ensure the normal operation of the device and the stability of the vertical reciprocating movement process of the cleaning rod 31.

[0044] Reference Figure 2 and Figure 4The push plate 5 is arranged on the top of the cleaning frame 3. A vertically placed support plate 33 is arranged on the top of the cleaning frame 3. The push plate 5 is fixedly connected to the top surface of the support plate 33. The support plate 33 is used to support the push plate 5. The discharge port 21 of the flocculation tank 2 is opened on the left side of the flocculation tank 2. The push plate 5 is tilted downward from left to right. The tilted push plate 5 can help guide the sludge to flow to the discharge port 21, ensure that the sludge moves according to the predetermined process, reduce the disordered flow of the sludge in the flocculation tank 2, and improve the discharge efficiency.

[0045] Reference Figure 2 and Figure 6 Furthermore, the bottom surface of the push plate 5 is connected with a scraper plate 6 in a sliding manner in the left and right directions, and a connecting rod 61 is hinged between the scraper plate 6 and the left side of the inner wall of the flocculation tank 2. During the vertical reciprocating movement of the push plate 5, under the action of the connecting rod 61, the scraper plate 6 slides left and right along the bottom surface of the push plate 5, which can effectively scrape off the sludge attached to the bottom surface of the push plate 5 and keep the push plate 5 clean. The push plate 5 and the scraper plate 6 are linked by the connecting rod 61, which can improve the automation of the device.

[0046] Reference Figure 4 and Figure 6 Furthermore, the front side, the rear side and the right side of the cleaning rack 3 are all connected with a water pipe 7. Specifically, if a water pipe 7 is provided on the left side of the cleaning rack 3, the water pipe 7 will affect the flow of sludge at the discharge port 21. A one-way valve is provided at the bottom of the inside of the water pipe 7, and a water pipe 2 8 is provided at the top of the push plate 5. The top of the water pipe 7 is connected to the water pipe 2 8. A water outlet 9 is provided on the bottom of the push plate 5, and the water pipe 2 8 is connected to the water outlet 9. In the process of the cleaning rack 3 moving downward, the water flow at the bottom of the flocculation tank body 2 enters the inside of the water pipe 7. As the water flow in the water pipe 7 increases, the water flow moves upward to the water pipe 2 8, and is sprayed to the sludge on the water surface inside the flocculation tank body 2 through the water outlet 9, which can wet the sludge floating on the water surface and solve the problem of the difficulty of sludge flow in the flocculation tank body 2 caused by sludge drying.

[0047] Reference Figure 5 Furthermore, a ball filter is provided at the bottom of the water pipe 7. It can reduce the situation where sludge enters the water pipe 7 as much as possible and ensure the normal operation of the structure.

[0048] The implementation principle of the chemical sludge drying treatment device of the embodiment of the present invention is: The sludge and the reagent are added into the flocculation tank 2 for flocculation, and the stirring element 22 stirs the sludge and the reagent to accelerate the flocculation process. The flocculated sludge enters the concentration and dehydration bin in the spiral press body 1 through the discharge port 21 on the flocculation tank 2 for dehydration and drying.

[0049] During the sludge discharge process, the air pipe 43 is inflated by an external air supply mechanism. During the inflation of the air pipe 43, the cleaning frame 3 moves upward, and the air outlet 44 blows air toward the bottom of the internal cavity of the flocculation tank 2 to scrape and clean the inner wall of the flocculation tank 2, thereby reducing the accumulation of sludge at the bottom of the flocculation tank 2. When the air pipe 43 stops blowing air, the cleaning frame 3 moves downward under the action of its own gravity and the action of the compression spring 45. During the downward movement of the cleaning frame 3, the gas in the air pipe 43 is blown out through the air outlet 44.

[0050] When the cleaning frame 3 moves back and forth vertically, the push plate 5 moves back and forth vertically, guiding the sludge to flow toward the discharge port 21, thereby accelerating the discharge efficiency and reducing the disordered flow of the sludge.

[0051] During the vertical reciprocating movement of the push plate 5 , the scraper plate 6 slides under the action of the connecting rod 61 to clean the bottom surface of the push plate 5 .

[0052] During the downward movement of the cleaning rack 3, the water in the flocculation tank 2 enters the water pipe 1 7. As the water flow in the water pipe 1 7 increases, the water flows upward to the water pipe 2 8 and is discharged through the water outlet 9, moistening the sludge floating on the water surface in the flocculation tank 2, thereby reducing the problem of sludge flow difficulty caused by sludge drying.

[0053] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
