Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge deep dewatering technology, and more specifically, to a sludge deep dewatering device. Background Technology
[0002] Deep sludge dewatering is a wastewater treatment technology that reduces the moisture content of sludge to a low level through specific treatment methods. Specifically, deep dewatering refers to reducing the moisture content of dewatered sludge to 55%-65%. Deep dewatering involves blending the sludge to change the structure of the sludge particles, thereby releasing water. However, the deep dewatering process usually requires mixing the sludge with a blending agent in a mixing device before transferring the mixture to a filtration device for dewatering, resulting in a relatively slow overall dewatering process and affecting the efficiency of deep sludge dewatering. Based on this, this utility model designs a deep sludge dewatering device to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a sludge deep dewatering device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A sludge deep dewatering device includes a frame, a water storage tank, an outer sealing cylinder, and a mixing filter cylinder. A telescopic cylinder is fixedly installed at the upper end of the frame. The outer sealing cylinder is fixedly installed on the telescopic end of the telescopic cylinder via a lifting seat. A feed port is provided on the front top side of the outer sealing cylinder, and a chemical inlet is provided on the rear top side of the outer sealing cylinder. A stirring assembly is provided on the outer sealing cylinder. A plurality of filter holes are spaced apart on the side of the mixing filter cylinder. The outer sealing cylinder is slidably sleeved on the outside of the mixing filter cylinder. The water storage tank is rotatably installed inside the frame via a rotating shaft. A flipping positioning assembly for driving the water storage tank and the mixing filter cylinder to flip over is provided on the frame. A first motor is fixedly installed at the bottom end of the water storage tank. A support shaft is fixedly connected to the drive end of the first motor.

The second motor is fixedly installed in the middle of the top of the outer sealing cylinder, the stirring shaft is fixedly connected to the drive end of the second motor, and the plurality of stirring blades are fixedly installed at intervals on the side of the stirring shaft.
[0007] As a preferred embodiment of this utility model, the bottom end of the water storage cylinder is fixedly connected to a water outlet pipe, and a solenoid valve is installed on the water outlet pipe.

[0010] As a preferred embodiment of this utility model, two columns are symmetrically fixedly installed inside the frame, and the lifting seat is slidably sleeved on the outside of the columns.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model utilizes an outer sealing cylinder to block the filter holes on the side of the mixing filter cylinder. Sludge and chemicals are introduced into the mixing filter cylinder through the feed port and chemical inlet port, respectively. A second motor drives the stirring shaft to rotate, and the stirring blades stir and mix the sludge and chemicals in the mixing filter cylinder.

At the same time, the stirring component moves outside the mixing filter cylinder, and the filter holes on the side of the mixing filter cylinder are in a flowing state. A first motor drives the support shaft and the mixing filter cylinder to rotate, and centrifugal force promotes the rapid separation of sludge and water. The water flows through the filter holes into the water storage tank for collection, thus completing the mixing and filtration treatment for deep dewatering of sludge.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 4 As shown, this utility model provides a sludge deep dewatering device, including a frame 1, a water storage tank 2, an outer sealing cylinder 3, and a mixing filter cylinder 5. A telescopic cylinder 101 is fixedly installed on the upper end of the frame 1. The outer sealing cylinder 3 is fixedly installed on the telescopic end of the telescopic cylinder 101 via a lifting seat 102. A feed port 301 is provided on the front side of the top of the outer sealing cylinder 3, and a chemical inlet port 302 is provided on the rear side of the top of the outer sealing cylinder 3. Sludge and chemicals can be fed into the mixing filter cylinder 5 through the feed port 301 and the chemical inlet port 302, respectively. A stirring assembly 4 is provided on the outer sealing cylinder 3. The side of the mixing filter cylinder 5 is provided with several filter holes 501 spaced apart. The outer sealing cylinder 3 is slidably sleeved on the outside of the mixing filter cylinder 5. The filter holes 501 on the side of the mixing filter cylinder 5 can be blocked by the outer sealing cylinder 3. The water storage cylinder 2 is rotatably installed on the inside of the frame 1 through the rotating shaft 201. The frame 1 is provided with a flip positioning component 6 for driving the water storage cylinder 2 and the mixing filter cylinder 5 to flip. The bottom end of the water storage cylinder 2 is fixedly installed with a first motor 202. The drive end of the first motor 202 is fixedly connected to a support shaft 203. The mixing filter cylinder 5 is fixedly installed on the end of the support shaft 203.
[0021] Among them, such as Figure 2As shown, the stirring assembly 4 includes a second motor 401, a stirring shaft 402, and several stirring blades 403. The second motor 401 is fixedly installed in the middle of the top of the outer sealing cylinder 3. The stirring shaft 402 is fixedly connected to the drive end of the second motor 401. Several stirring blades 403 are fixedly installed at intervals on the side of the stirring shaft 402. The second motor 401 drives the stirring shaft 402 to rotate, and the stirring blades 403 can be used to stir and mix the sludge and the agent in the mixing filter cartridge 5.
[0022] Among them, such as Figure 2 As shown, the bottom end of the water storage cylinder 2 is fixedly connected to the water outlet pipe 204, and the water outlet pipe 204 is equipped with a solenoid valve 205. When the solenoid valve 205 is opened, the water stored in the water storage cylinder 2 can be discharged through the water outlet pipe 204.
[0023] Among them, such as Figure 2 and Figure 3 As shown, the flipping positioning assembly 6 includes a third motor 601, a drive shaft 602, and a positioning gear 603. The third motor 601 is fixedly mounted on the frame 1, the drive shaft 602 is fixedly connected to the drive end of the third motor 601, and the positioning gear 603 is fixedly connected to the end of the drive shaft 602. A toothed ring 2011 is fixedly sleeved on the outside of the rotating shaft 201. The positioning gear 603 meshes with the toothed ring 2011. By using the third motor 601 to drive the positioning gear 603 to rotate, the water storage cylinder 2 and the mixing filter cylinder 5 can be flipped.
[0024] Among them, such as Figure 3 As shown, the outer diameter of the gear ring 2011 is larger than the diameter of the positioning gear 603, which achieves the purpose of enabling the positioning gear 603 to drive the gear ring 2011 to rotate relatively slowly.
[0025] Among them, such as Figure 2 As shown, two columns 103 are symmetrically fixedly installed inside the frame 1. The lifting seat 102 is slidably sleeved on the outside of the columns 103. The columns 103 can play a good guiding role for the lifting seat 102.
[0026] The working principle of this utility model:
[0027] During use, the outer sealing cylinder 3 can be used to seal the filter holes 501 on the side of the mixing filter cylinder 5. Sludge and chemicals are introduced into the mixing filter cylinder 5 through the feed port 301 and the chemical inlet 302, respectively. The second motor 401 drives the stirring shaft 402 to rotate, and the stirring blades 403 mix the sludge and chemicals inside the mixing filter cylinder 5. After mixing, the second motor 401 is turned off, and the telescopic cylinder 101 drives the lifting seat 102 and the outer sealing cylinder 3 to rise, causing the outer sealing cylinder 3 to detach from the mixing filter cylinder 5. Simultaneously, the stirring assembly 4 moves outside the mixing filter cylinder 5, and the filter holes 501 on the side of the mixing filter cylinder 5 are in a flowing state. The first motor 202 drives the support shaft 203 to rotate with the mixing filter cylinder 5. Centrifugal force promotes rapid separation of sludge and water, allowing the water to flow through the filter holes 501 into the water storage tank 2 for collection. This completes the mixing and filtration process for deep dewatering of the sludge, eliminating the need to transfer the sludge from the mixing equipment to the filtration equipment. After the deep dewatering of the sludge is completed, the solenoid valve 205 is opened to discharge the water stored in the water storage tank 2 through the outlet pipe 204. The solenoid valve 205 is then closed, and the third motor 601 drives the positioning gear 603 to rotate forward, causing the water storage tank 2 and the mixing filter cylinder 5 to flip downwards, facilitating the discharge of the deeply dewatered sludge from the mixing filter cylinder 5. Finally, the third motor 601 drives the positioning gear 603 to rotate in the opposite direction, causing the water storage tank 2 and the mixing filter cylinder 5 to flip upwards and reset.
