Description

Technical Field

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

[0002] Muddy water is generally discharged directly without treatment. Muddy water can pollute natural water bodies, cause the death of fish, shrimp, algae and microorganisms in natural water bodies, destroy the food chain and cause ecological imbalance.

With the increase of people's environmental awareness and the requirements of environmental protection laws and regulations, protecting the environment has become a consensus, and muddy water must be treated before it can be discharged. Conventionally, after the muddy water is statically precipitated, the upper clarified wastewater is centrally treated, but the precipitated sludge still contains a lot of water.

[0024] 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.

[0025] 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.

[0026] In this embodiment, each push plate 210 is a telescopic plate, each push plate 210 includes a fixed portion and a sliding portion, the sliding portion slides inside the fixed portion, so that the length of the push plate 210 has a minimum value and a maximum value. The adjustment assembly includes a transmission plate 410, an adjustment rod 440 and an adjustment gear 430, the transmission plate 410 is horizontally arranged, the transmission plate 410 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 portion of the push plate 210 through a connecting rod 420, the connecting rod 420 is fixedly connected to the push plate 210, and the connecting rod 420 is rotatably connected to the transmission plate 410, so that 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 rotating sleeve 310 and the fixed cylinder 110 rotate relative to each other, and the rotating sleeve 310 further squeezes the sludge entering the first notch 113. The adjusting gear 430 is arranged on the transmission plate 410 to rotate 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 and the adjusting gear 430 are meshed and transmitted. Further, a second chute 411 with an opening facing upward is provided on the transmission plate 410, and a push block 412 is slidably provided in the second chute 411, and the push block 412 abuts against the adjusting rod 440. A second elastic member is fixedly provided between the push block 412 and the end of the second chute 411, and the second elastic member drives the adjusting rod 440 to always 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.

[0027] In this embodiment, each group of transmission plates 410 is provided with a first limiting groove 414 and a second limiting groove 415 opening downward, the first limiting groove 414 is provided at the axis of the transmission plate 410, and the second limiting groove 415 is provided at the front side of the first limiting groove 414 rotating counterclockwise. Each push plate 210 is provided with a first sliding groove opening upward at the upper end, and a limiting block 212 is slidably provided in the first sliding groove, the upper end surface of the limiting block 212 is smoothly connected to the side wall, and the limiting block 212 is fixedly connected to the end of the first sliding groove by a first elastic member, and further, the first elastic member is a first spring 213. In the initial state, the limiting block 212 is in the first limiting groove 414, so that the push plate 210 extends along the radial direction of the fixed cylinder 110, and the length of the push plate 210 is at a minimum value state. When the moisture content of the sludge in the storage chamber 111 gradually decreases, the viscosity of the sludge gradually increases, and the sludge accumulates at the edge of the storage chamber 111. When the motor drives the push plate 210 to rotate counterclockwise around the filter shaft 140, the resistance of the sludge to the outer end of the fixed part of the push plate 210 gradually increases until the force of the power source driving the push plate 210 to rotate overcomes the resistance of the limit block 212 to the push plate 210. At this time, the viscosity of the sludge reaches a first preset value. As the motor rotates, the push plate 210 is extended from the minimum value of the length of the push plate 210 to the maximum value. At this time, there is a fixed angle between the push plate 210 and the transmission plate 410, and the limit block 212 enters the second limit groove 415 from the first limit groove 414, and the push plate 210 is deflected to drive the adjusting gear 430 to rotate.

[0028] In this embodiment, an arc-shaped groove with an opening downward is provided on the adjusting gear 430, and a slider 432 is slidably provided in the arc-shaped groove. The slider 432 is fixedly connected to the transmission plate 410, and a third elastic member is fixedly provided between the slider 432 and the end of the arc-shaped groove. Furthermore, the third elastic member is a third spring 433. The third spring 433 is gradually charged 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 push plate 210 is reduced. Under the action of the reset force of the third spring 433, the adjusting gear 430 rotates in the opposite direction, so that the blocking plate 320 blocks the third notch 311, and at the same time, the length of the push plate 210 is changed from a maximum state to a minimum state.

[0029] In combination with the above embodiments, the use principle and working process of the present invention are as follows: During operation, by utilizing the different densities of water and mud in the sludge, the pushing plate 210 pushes the sludge to rotate in the storage chamber 111, so that the water in the sludge is separated from the mud. When the mud enters the first notch 113, the relative rotation of the rotating sleeve 310 and the fixed cylinder 110 further squeezes the mud entering the first notch 113. According to the different resistances of the pushing plate 210 to the different viscosities of the mud, the opening state of the blocking plate 320 to the third notch 311 is changed, and the mud is discharged from the storage chamber 111 with substantially the same water content.

[0030] In the initial state, the three push plates 210 extend in the radial direction of the fixed cylinder 110, and the limit blocks 212 provided on the three push plates 210 enter the first limit groove 414 under the action of the first spring 213, and the limit blocks 212 hinder the deflection of the push plates 210. The blocking plate 320 blocks the third notch 311 in the initial state.

[0031] The sludge is placed in the storage chamber 111, and the three push plates 210 are driven counterclockwise by the motor to rotate counterclockwise around the side wall of the filter shaft 140. The three push plates 210 push the sludge to rotate in the storage chamber 111. The water and mud in the sludge are subjected to different centrifugal forces according to their different densities, so that the mud gradually accumulates on the side wall of the fixed cylinder 110 and enters the first notch 113. The water in the sludge gradually moves toward the axis of the fixed cylinder 110. The bottom of the fixed cylinder 110 is fixedly provided with a conical cylinder 120, and the conical cylinder 120 is fixedly provided with a conical cylinder 120. One end of the conical cylinder 120 is connected to the second notch, and the connection between the conical cylinder 120 and the lower end surface of the fixed cylinder 110 is smoothly connected, and the water in the sludge enters the conical cylinder 120. Since the filter shaft 140 is fixedly connected to the axis of the conical cylinder 120, the filter shaft 140 is hollow inside, and the side wall is provided with a plurality of filter holes that penetrate inside and outside, the water in the sludge enters the inside of the filter shaft 140 after being filtered through the filter holes, and the inside of the filter shaft 140 is connected to the drain pipe 130, and the water in the sludge is discharged from the fixed cylinder 110 under the diversion effect of the drain pipe 130. When the push plate 210 rotates around the side wall of the filter shaft 140, the end of the push plate 210 simultaneously cleans the filter holes on the side wall of the filter shaft 140 to reduce the clogging of the filter holes by the mud in the sludge.

[0032] A transmission plate 410 is arranged 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 arranged between the middle part 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 the transmission plate 410 up and down, 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, the rotating sleeve 310 is driven to rotate synchronously on the side wall of the fixed cylinder 110. When the pushing plate 210 pushes the sludge to rotate in the storage chamber 111, part of the sludge enters the first notch 113. Since the two vertical side walls of the first notch 113 are a straight surface and an arc surface respectively, and the arc surface is arranged on the front side of the first notch 113 when rotating counterclockwise, 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, thereby improving the dehydration performance of the sludge.

[0033] As the water and mud in the sludge separate, the viscosity of the mud gradually increases, and the resistance of the push plate 210 to push the sludge to rotate in the storage chamber 111 gradually increases, and the mud accumulates on the edge of the side wall of the storage chamber 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 extends, 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 is deflected, 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 adjusting gear 430 to rotate. The adjusting rod 440 is always engaged with the adjusting gear 430 under the action of the push block 412. At this time, the rotation of the adjusting gear 430 drives the sealing plate 320 to slide in the slideway 312. The third spring 433 is gradually charged when the adjusting gear 430 rotates. The sliding of the sealing plate 320 gradually opens the third notch 311. When the third notch 311 is rotated to be connected with any one of the first notches 113, mud can be discharged.

[0034] When the mud with less water content is discharged from the storage chamber 111 through the third notch 311, the resistance of the mud to the rotation of the push plate 210 is reduced. Under the action of the third spring 433, the adjustment gear 430 rotates in the opposite direction, and the blocking plate 320 is driven by the adjustment rod 440 to block the third notch 311 again. When the adjustment gear 430 rotates in the opposite direction, the push plate 210 overcomes the obstruction 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 is converted from a maximum state to a minimum state. In this way, the sludge in the storage chamber 111 is dehydrated reciprocatingly, so that the mud and water in the sludge are separated.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
