A muddy water separation device

Abstract

The present invention relates to the field of sludge treatment, and particularly to a mud-water separation device, which includes a fixed cylinder, a filtering shaft, a pushing plate and a rotating sleeve. The sludge is placed in the placing cavity. The power source drives the three pushing plates to rotate around the filtering shaft simultaneously, pushing the sludge to rotate in the placing cavity. The sludge is subjected to centrifugal force, gradually pushing the mud to the peripheral side wall of the fixed cylinder, and the water gradually enters the interior of the filtering shaft through the filtering holes on the side wall of the filtering shaft and is discharged from the fixed cylinder through the second notch. The viscosity of the sludge gradually increases, and the resistance when the pushing plate pushes the sludge to rotate increases. The third notch on the side wall of the rotating sleeve is opened, enabling the sludge to pass through the first notch and then be discharged from the fixed cylinder through the third notch. As the sludge with high viscosity is discharged from the fixed cylinder, the resistance of the pushing plate to push the sludge decreases, and the third notch is blocked again by the blocking plate. The sludge is continuously dehydrated, improving the efficiency of sludge dehydration, and at the same time ensuring that the water content of the dehydrated sludge remains consistent.

Description

Technical Field

[0001] The present invention relates to the field of sludge treatment, and particularly to a mud-water separation device. Background Art

[0002] Generally, mud-water is directly discharged without treatment. Mud-water can pollute natural water bodies, causing the death of fish, shrimps, algae, and microorganisms in natural water bodies, destroying the food chain, and leading to ecological imbalance. Using traditional methods not only has a great impact on people's living environment, but even causes serious pollution, damage, and serious waste of resources. With the increase of people's environmental protection awareness and the requirements of environmental protection laws and regulations, protecting the environment has become a consensus, and mud-water must be treated before being discharged. After the conventional mud-water is statically precipitated, the upper clarified wastewater is centrally treated, but the precipitated sludge still contains a large amount of water. When treating the precipitated sludge, the existing method is to lift the sludge using a filter net and utilize gravity to separate the sludge from the water. Its disadvantage is extremely low efficiency. Summary of the Invention

[0003] The present invention provides a mud-water separation device to solve the problem of low mud-water separation efficiency in existing sludge.

[0004] The following technical scheme is adopted for a mud-water separation device of the present invention:

[0005] A mud-water separation device includes a fixed cylinder, a filtering shaft, a pushing plate, and a rotating sleeve; the fixed cylinder has a placing cavity with an upward opening, at least one first notch is provided on the circumferential side wall of the fixed cylinder, and a second notch is provided in the middle of the lower end of the fixed cylinder; the filtering shaft is hollow inside, and a plurality of filtering holes are provided on the side wall of the filtering shaft. The filtering shaft is coaxially arranged inside the fixed cylinder, and the filtering cylinder communicates with the second notch; at least three groups of pushing plates are provided, and the three groups of pushing plates are evenly distributed along the circumferential side wall of the filtering shaft. One end of each pushing plate abuts against the side wall of the placing cavity, and the other end abuts against the outer side wall of the filtering cylinder. The plurality of pushing plates are simultaneously driven by a power source to rotate around the side wall of the filtering shaft; the rotating sleeve is arranged outside the fixed cylinder, at least three third notches are provided on the side wall of the rotating sleeve, and the three third notches are evenly distributed along the circumferential direction of the rotating sleeve. A transmission connection is provided between the rotating sleeve and the pushing plate. When the pushing plate rotates around the filtering shaft, the rotating sleeve rotates outside the fixed cylinder; at least three groups of blocking plates are slidably arranged on the side wall of the rotating sleeve. The blocking plates are used to open or block the third notches. When the viscosity of the sludge in the placing cavity reaches a first preset value, the blocking plates open the third notches.

[0006] Furthermore, each pushing plate is a telescopic plate, and the length of each pushing plate has a minimum value and a maximum value. A transmission connection is provided between the pushing plate and the blocking plate through an adjusting component. When the viscosity of the sludge in the placing cavity reaches the first preset value, the length of the pushing plate is converted from the minimum value to the maximum value, and the adjusting component adjusts the blocking state of the blocking plate for the third notch.

[0007] Further, there are three sets of adjusting components. Each set of adjusting components includes a transmission plate, an adjusting rod, and an adjusting gear. The transmission plate is fixedly arranged at the upper end of the rotating sleeve; the outer end of the transmission plate is rotatably connected to the outer end of the pushing plate through a connecting rod, and the connecting rod is fixedly connected to the pushing plate; the adjusting gear is rotatably connected to the transmission plate, and the rotating shaft of the adjusting gear is fixedly connected to the connecting rod; one end of the adjusting rod is rotatably connected to the blocking plate, and the side wall of the adjusting rod is meshed with the adjusting gear.

[0008] Further, the first notch is vertically arranged. One of the vertical side walls of the first notch is a straight surface, and the other vertical side wall of the first notch is an arc surface, so that the distance between the two vertical side walls of the first notch gradually increases from the inside to the outside. When the length of the pushing plate is at the minimum value, the pushing plate rotates synchronously with the rotating sleeve, and the rotating sleeve further extrudes the sludge entering the first notch.

[0009] Further, each transmission plate is provided with a first limiting groove and a second limiting groove with openings downward. Each upper end of the pushing plate is provided with a first sliding groove with an opening upward. A limiting block is slidably arranged in the first sliding groove, and the limiting block is fixedly connected to the end of the first sliding groove through a first elastic member. When the length of the pushing plate converts from the minimum value to the maximum value, the limiting block converts from the first limiting groove to the second limiting groove.

[0010] Further, the transmission plate is provided with a second sliding groove with an opening upward. A pushing block is slidably arranged in the second sliding groove. The pushing block abuts against the adjusting rod, and a second elastic member is fixedly arranged between the pushing block and the end of the second sliding groove. The second elastic member drives the adjusting rod to always be meshed with the adjusting gear.

[0011] Further, the adjusting gear is provided with an arc-shaped groove with an opening downward. A slider is slidably arranged in the arc-shaped groove. The slider is fixedly connected to the transmission plate, and a third elastic member is fixedly arranged between the slider and the end of the arc-shaped groove.

[0012] Further, a conical cylinder is fixedly arranged at the lower end of the fixed sleeve. The upper end of the conical cylinder is communicated with the second notch, and the lower end of the conical cylinder is communicated with the drain pipe.

[0013] Further, the power source includes a driving ring and a motor. The driving ring is rotatably arranged at the upper end of the filter shaft. At least three driving rods are arranged on the driving ring. The three driving rods are fixedly arranged circumferentially and uniformly along the side wall of the driving ring. Each driving rod is rotatably connected to a pushing plate; the power output shaft of the motor is fixedly connected to the driving ring.

[0014] The beneficial effects of the present invention are as follows: A sludge-water separation device of the present invention includes a fixed cylinder, a filtering shaft, a pushing plate, and a rotating sleeve. Sludge containing a large amount of water is placed in the placement cavity. The power source drives the three pushing plates to rotate around the filtering shaft simultaneously, pushing the sludge to rotate in the placement cavity, causing the sludge to be subjected to centrifugal force. Utilizing the fact that the density of mud is higher than that of water, the mud is gradually pushed to the peripheral side wall of the fixed cylinder, and the water gradually enters the interior of the filtering shaft through the filtering holes on the side wall of the filtering shaft and is discharged from the fixed cylinder through the second notch. As the water in the sludge is discharged, the viscosity of the sludge increases, and the resistance when the pushing plate pushes the sludge to rotate increases. The third notch on the side wall of the rotating sleeve is opened, enabling the sludge to pass through the first notch and then be discharged from the fixed cylinder through the third notch. As the sludge with high viscosity is discharged from the fixed cylinder, the resistance of the pushing plate to push the sludge decreases, and the third notch is blocked again by the blocking plate. The sludge is continuously dehydrated, improving the efficiency of sludge dehydration and ensuring that the water content of the dehydrated sludge remains consistent.

[0032] An embodiment of a muddy water separation device of the present invention, as Figures 1 to 12 shown, includes a fixed cylinder 110, a filter shaft 140, a push plate 210 and a rotating sleeve 310.

[0033] The fixed cylinder 110 is vertically arranged. The fixed cylinder 110 has a storage cavity 111 with an upward opening. Four legs 112 are fixedly arranged at the lower end of the fixed cylinder 110. The legs 112 are used to fixedly support the fixed cylinder 110. A plurality of first notches 113 are arranged on the circumferential side wall of the fixed cylinder 110. The plurality of first notches 113 are evenly distributed along the circumferential side wall of the fixed cylinder 110. Each first notch 113 is vertically arranged. One vertical side wall of the first notch 113 is a straight surface, and the other vertical side wall of the first notch 113 is an arc surface, so that the distance between the two vertical side walls of the first notch 113 from the inside to the outside gradually increases, and the arc side wall of the first notch 113 is arranged on the front side of the straight side wall in the counterclockwise rotation direction. A circular second notch is arranged in the middle of the lower end surface of the fixed cylinder 110. The second notch is coaxially arranged with the fixed cylinder 110. A conical cylinder 120 is fixedly arranged on the lower end surface of the fixed cylinder 110. The conical cylinder 120 has a channel penetrating up and down. The diameter of the channel of the conical cylinder 120 gradually decreases from bottom to top. The upper end of the conical cylinder 120 is fixedly and coaxially connected to the lower end of the fixed cylinder 110, and the channel of the conical cylinder 120 is smoothly communicated with the second notch. A drain pipe 130 is fixedly arranged at the lower end of the conical cylinder 120.

[0034] The filter shaft 140 is a cylindrical structure. The filter shaft 140 is vertically arranged. The inside of the filter shaft 140 is hollow. Filter holes penetrating inside and outside are arranged on the circumferential side wall of the filter shaft 140. The filter cylinder is coaxially arranged in the storage cavity 111, and the lower end of the filter cylinder is fixedly connected to the lower end of the conical cylinder 120, so that the inside of the filter cylinder is communicated with the drain pipe 130.

[0035] There are three groups of push plates 210, and the three groups of push plates 210 are evenly distributed along the side wall of the filter shaft 140. One end of each push plate 210 abuts against the side wall of the storage cavity 111, and the other end abuts against the outer side wall of the filter cartridge. The multiple push plates 210 are simultaneously driven by a power source to rotate around the side wall of the filter shaft 140. Specifically, the power source includes a drive ring 150 and a motor. The drive ring 150 is rotatably arranged at the upper end of the filter shaft 140. Three drive rods 151 are arranged on the drive ring 150. The three drive rods 151 are evenly fixedly arranged along the circumference of the side wall of the drive ring 150, and each drive rod 151 is rotatably connected to a push plate 210. The motor is fixedly arranged above the filter shaft 140 through a fixing frame, and the power output shaft of the motor is fixedly connected to the driving ring 150. When the motor rotates counterclockwise, the pushing plate 210 rotates counterclockwise around the side wall of the filter shaft 140. The pushing plate 210 pushes the sludge to rotate in the storage chamber 111, so that the sludge is subjected to centrifugal force. The density of the mud and water in the sludge is different, so that the mud accumulates on the outside of the storage chamber 111, and the water gradually passes through the conical cylinder 120 and enters the interior of the filter shaft 140 through the filter holes on the side wall of the filter shaft 140, and finally is discharged from the fixed cylinder 110 through the drain pipe 130.

[0036] The rotating sleeve 310 is coaxially arranged outside the fixed cylinder 110, the inner side wall of the rotating sleeve 310 is always in contact with the outer side wall of the fixed cylinder 110, and the lower end of the rotating sleeve 310 is rotatably connected with the lower end of the fixed cylinder 110. The side wall of the rotating sleeve 310 is provided with three third notches 311 penetrating inside and outside, and the three third notches 311 are evenly distributed along the circumferential direction of the side wall of the rotating sleeve 310. Each third notch 311 is vertically arranged, and the length of each third notch 311 is the same as the length of the first notch 113. Three slideways 312 with upward openings are arranged on the side wall of the rotating sleeve 310, each slideway 312 is arranged on one side of a third notch 311, each slideway 312 is connected to a third notch 311, and the vertical length of each slideway 312 is greater than the vertical length of the third notch 311. A blocking plate 320 is slidably disposed in each slideway 312. When the blocking plate 320 slides in the slideway 312, the third notch 311 is opened or blocked. When the third notch 311 is opened and the rotating sleeve 310 rotates to communicate with any first notch 113, the mud accumulated outside the storage cavity 111 is discharged from the fixed cylinder 110 through the third notch 311.

[0037] In this embodiment, each push plate 210 is connected to a sealing plate 320 through a group of adjustment components. When the push plate 210 rotates around the filter shaft 140, the rotating sleeve 310 rotates synchronously with the push plate 210, and the sealing plate 320 is controlled to block or open the third gap 311 according to the viscosity of the sludge in the storage chamber 111.

[0038] In this embodiment, each push plate 210 is a telescopic plate. Each push plate 210 includes a fixed part and a sliding part. The sliding part slides inside the fixed part, so that the length of the push plate 210 has a minimum value and a maximum value. The adjusting assembly includes a transmission plate 410, an adjusting rod 440, and an adjusting gear 430. The transmission plate 410 is horizontally arranged and extends along the radial direction of the storage cavity 111. The outer end of the transmission plate 410 is fixedly arranged at the upper end of the rotating sleeve 310, and the outer end of the transmission plate 410 is arranged at the edge of the slideway 312. The middle part of the transmission plate 410 is connected to the fixed part of the push plate 210 through a connecting rod 420. The connecting rod 420 is fixedly connected to the push plate 210 and is rotatably connected to the transmission plate 410. When the push plate 210 rotates counterclockwise around the filter shaft 140 driven by the motor, the rotating sleeve 310 rotates counterclockwise around the side wall of the fixed sleeve synchronously. The relative rotation of the rotating sleeve 310 and the fixed cylinder 110 further squeezes the sludge entering the first notch 113. The adjusting gear 430 is rotatably arranged on the transmission plate 410 around its own axis, and the rotating shaft of the adjusting gear 430 is fixedly connected to the connecting rod 420. One end of the adjusting rod 440 is connected to the upper end of the blocking plate 320, and the adjusting rod 440 can swing in the horizontal direction around the connection point of the blocking plate 320. The side wall of the adjusting rod 440 is provided with a tooth groove, and the adjusting rod 440 is in meshing transmission with the adjusting gear 430. Further, a second chute 411 with an upward opening is arranged on the transmission plate 410. A push block 412 is slidably arranged in the second chute 411. The push block 412 abuts against the adjusting rod 440. A second elastic member is fixedly arranged between the push block 412 and the end of the second chute 411. The second elastic member drives the adjusting rod 440 to always be in mesh with the adjusting gear 430. The second elastic member is a second spring 413, and the second spring 413 is always in a compressed state.

[0039] In this embodiment, a first limiting groove 414 and a second limiting groove 415 with downward openings are provided on each driving plate 410. The first limiting groove 414 is arranged at the axis of the driving plate 410, and the second limiting groove 415 is arranged on the front side of the first limiting groove 414 rotating counterclockwise. An upward-opening first sliding groove is provided at the upper end of each pushing plate 210. A limiting block 212 is slidably arranged in the first sliding groove. The upper end surface of the limiting block 212 is smoothly connected to the side wall. The limiting block 212 is fixedly connected to the end of the first sliding groove through a first elastic member. Further, the first elastic member is a first spring 213. In the initial state, the limiting block 212 is located in the first limiting groove 414, so that the pushing plate 210 extends along the radial direction of the fixed cylinder 110. At this time, the length of the pushing plate 210 is in a minimum state. When the moisture content of the sludge in the storage cavity 111 gradually decreases, the viscosity of the mud gradually increases, and the mud accumulates at the edge of the storage cavity 111. When the motor drives the pushing plate 210 to rotate counterclockwise around the filter shaft 140, the resistance of the mud to the outer end of the fixed part of the pushing plate 210 gradually increases. Until the force driving the pushing plate 210 to rotate by the power source overcomes the resistance of the limiting block 212 to the pushing plate 210, at this time, the viscosity of the mud reaches the first preset value. As the motor rotates, the pushing plate 210 extends, from the minimum value of the length of the pushing plate 210 to the maximum value. At this time, there is a fixed angle between the pushing plate 210 and the driving plate 410, and the limiting block 212 enters the second limiting groove 415 from the first limiting groove 414, and the deflection of the pushing plate 210 drives the adjusting gear 430 to rotate.

[0040] In this embodiment, an arc-shaped groove with a downward opening is provided on the adjusting gear 430. A slider 432 is slidably arranged in the arc-shaped groove. The slider 432 is fixedly connected to the driving plate 410. A third elastic member is fixedly arranged between the slider 432 and the end of the arc-shaped groove. Further, the third elastic member is a third spring 433. The third spring 433 is gradually stored with energy when the adjusting gear 430 rotates. When the dehydrated mud is discharged from the storage cavity 111 through the third notch 311, the resistance of the mud to the pushing plate 210 decreases. Under the action of the restoring force of the third spring 433, the adjusting gear 430 rotates in the reverse direction, so that the blocking plate 320 blocks the third notch 311, and at the same time, the length of the pushing plate 210 changes from the maximum state to the minimum state.

[0041] Combining the above embodiments, the working principle and process of the present invention are as follows:

[0042] During operation, by utilizing the different densities of water and sludge in the sludge, when the sludge is pushed by the pushing plate 210 to rotate in the placement cavity 111, the water and sludge in the sludge are separated. When the sludge enters the first notch 113, the relative rotation of the rotating sleeve 310 and the fixed cylinder 110 further squeezes the sludge entering the first notch 113. According to the different viscosities of the sludge, the resistance to the pushing plate 210 is different, and the opening state of the blocking plate 320 for the third notch 311 is changed to discharge the sludge from the placement cavity 111 under the condition that the water content is approximately the same.

[0043] In the initial state, the three pushing plates 210 extend along the radial direction of the fixed cylinder 110. The limiting blocks 212 provided on the three pushing plates 210 enter the first limiting grooves 414 under the action of the first springs 213, and the limiting blocks 212 hinder the deflection of the pushing plates 210. The blocking plate 320 blocks the third notch 311 in the initial state.

[0044] Place the sludge in the placement cavity 111. The three pushing plates 210 are driven counterclockwise by the motor to rotate counterclockwise around the side wall of the filter shaft 140. The three pushing plates 210 push the sludge to rotate in the placement cavity 111. Due to the different densities of water and sludge in the sludge, the centrifugal forces received by the water and sludge in the sludge are different, causing the sludge to gradually accumulate on the side wall of the fixed cylinder 110 and enter the first notch 113. The water in the sludge gradually approaches the axis of the fixed cylinder 110. A conical cylinder 120 is fixedly arranged at the bottom of the fixed cylinder 110, and one end of the conical cylinder 120 is communicated with the second notch. The connection between the conical cylinder 120 and the lower end surface of the fixed cylinder 110 is smoothly connected. The water in the sludge enters the conical cylinder 120. Since a filter shaft 140 is fixedly connected to the axis of the conical cylinder 120, the inside of the filter shaft 140 is hollow, and the side wall is provided with a plurality of through holes penetrating inside and outside. After the water in the sludge passes through the filtration of the through holes, it enters the inside of the filter shaft 140. The inside of the filter shaft 140 is communicated with the drain pipe 130, and the water in the sludge is discharged from the fixed cylinder 110 under the guiding action of the drain pipe 130. When the pushing plate 210 rotates around the side wall of the filter shaft 140, the end of the pushing plate 210 simultaneously cleans the through holes on the side wall of the filter shaft 140 to reduce the blockage of the through holes by the sludge in the sludge.

[0045] A transmission plate 410 is provided between the outer end of the push plate 210 and the rotating sleeve 310. The transmission plate 410 is arranged along the radial direction of the rotating sleeve 310. A connecting rod 420 is provided between the middle of the transmission plate 410 and the push plate 210. The connecting rod 420 is fixedly connected to the push plate 210. The connecting rod 420 penetrates through the transmission plate 410 vertically, and the connecting rod 420 is rotatably connected to the transmission plate 410. When the push plate 210 rotates around the side wall of the filter shaft 140, it drives the rotating sleeve 310 to rotate synchronously on the side wall of the fixed cylinder 110. When the push plate 210 pushes the sludge to rotate in the placement cavity 111, part of the sludge enters the first notch 113. Since the two vertical side walls of the first notch 113 are respectively a straight surface and an arc surface, and the arc surface is arranged on the front side of the counterclockwise rotation of the first notch 113, when the rotating sleeve 310 rotates counterclockwise around the fixed cylinder 110, the rotating sleeve 310 further squeezes the sludge entering the first notch 113, improving the dehydration performance of the sludge.

[0046] As the water and mud in the sludge are separated, the viscosity of the mud gradually increases, and the resistance of the push plate 210 to push the sludge to rotate in the placement cavity 111 gradually increases, and the mud accumulates at the edge of the side wall of the placement cavity 111 under the action of centrifugal force. When the force of the motor driving the push plate 210 to rotate overcomes the resistance of the limit block 212 to the push plate 210, the push plate 210 elongates, and the limit block 212 rotates from the first limit groove 414 to the second limit groove 415. At this time, the angle between the push plate 210 and the transmission plate 410 deflects, and the length of the push plate 210 changes from the minimum value to the maximum value. The angular deflection of the push plate 210 drives the adjustment gear 430 to rotate. The adjustment rod 440 is always engaged with the adjustment gear 430 under the action of the push block 412. At this time, the rotation of the adjustment gear 430 drives the sealing plate 320 to slide in the slideway 312, and the third spring 433 is gradually energized when the adjustment gear 430 rotates. The sliding of the sealing plate 320 gradually opens the third notch 311. When the third notch 311 rotates to communicate with any one of the first notches 113, mud can be discharged.

[0047] When the mud with less water content is discharged from the placement cavity 111 through the third notch 311, the resistance of the mud to the rotation of the push plate 210 decreases. Under the action of the third spring 433, the adjustment gear 430 rotates in the reverse direction, driving the sealing plate 320 to block the third notch 311 again through the adjustment rod 440. When the adjustment gear 430 rotates in the reverse direction, the push plate 210 overcomes the resistance of the limit block 212 in the second limit groove 415, so that the limit block 212 enters the first limit groove 414 again. At this time, the length of the push plate 210 changes from the maximum state to the minimum state. In this way, the sludge in the placement cavity 111 is dehydrated repeatedly, separating the mud and water in the sludge.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
