Description

Technical Field

[0001] The invention relates to the technical field of gypsum slurry dehydration devices, in particular to a gypsum slurry dehydration device. Background Art

[0002] At present, the gypsum dehydration system mainly adopts a two-stage dehydration process to ensure that the water in the gypsum slurry is efficiently removed to meet the requirements of subsequent utilization or disposal. The first stage of dehydration usually adopts cyclone concentration centrifugal separation technology to separate the solid particles and water in the gypsum slurry through a cyclone to achieve initial dehydration. The underflow slurry then enters the gypsum slurry tank, and is then pumped to the gypsum slurry distributor by the gypsum slurry discharge pump to prepare for the second stage of dehydration.

[0003] In the first stage of dehydration, the separation and screening function of the hydrocyclone is crucial to the dehydration efficiency. However, the viscosity of limestone slurry easily adheres to the inner wall of the hydrocyclone, which is not only difficult to clean, but also may affect reuse and may cause drainage obstruction, thus causing hydrocyclone blockage. When blockage occurs, the staff often does not have time to check it immediately, or the machine needs to be shut down for unblocking after blockage, which greatly reduces work efficiency and increases maintenance costs.

[0013] As a preferred solution of the gypsum slurry dehydration device of the present invention, wherein: the rotating ring is fixedly connected to the inner gear ring;

[0014] The rotating ring includes an annular groove extending through the inner side thereof;

[0015] The anti-blocking assembly includes a plurality of gears meshing with the inner gear ring, a support frame arranged on the upper side of the gears, and a sleeve arranged at the bottom of the cyclone.

[0016] As a preferred solution of the gypsum slurry dehydration device of the present invention, the clearing component includes a sliding rod slidably connected to the annular groove, a connecting piece arranged on the inner side of the sliding rod, a ring arranged on the inner side of the connecting piece, and a clearing piece arranged at the bottom of the sleeve.

[0018] The sleeve is movably sleeved and arranged at the bottom of the cyclone.

[0019] As a preferred embodiment of the gypsum slurry dehydration device of the present invention, the sleeve comprises a scraper arranged at the top thereof, a vertical groove arranged at the outside of the sleeve, and a horizontal groove arranged at the bottom of the sleeve;

[0020] The vertical groove is fixedly engaged with the gear.

[0021] As a preferred solution of the gypsum slurry dehydration device of the present invention, wherein: the connecting member includes a vertical plate arranged on the inner side of the sliding rod, a horizontal plate arranged on one side of the vertical plate, and a through hole arranged on the inner side of the horizontal plate;

The up and down movement of the cross plate and the dredging piece avoids the wear of the sleeve, and the pressure plate maintains the state of detecting the flow of gypsum slurry under the action of the fixed ear. When the flow is abnormal, the rebound action of the spring triggers the U-shaped ring to snap into the cross groove, realizing the synchronous movement of the sleeve and the cross plate, and automatically clearing the cyclone. As the flow is restored, the pressure plate is pressed down to re-detect and maintain the cyclone unobstructed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1, reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, and provides a gypsum slurry dehydration device, which includes a dehydration unit 100, including a slurry box 101, a plurality of cyclones 102 arranged in a circumferential array above the slurry box 101, a liquid inlet pipe 103 arranged above the cyclone 102, a liquid outlet pipe 104 arranged at one side of the liquid inlet pipe 103, and a water collecting tank 105 arranged at one side of the liquid outlet pipe 104;

[0041] The anti-blocking unit 200 includes an outer gear ring 201 disposed on the outside of the slurry box 101, a coupling member 202 disposed on the inside of the outer gear ring 201, a swivel 203 disposed on the bottom of the coupling member 202, a plurality of anti-blocking components 204 disposed in a circumferential array on the inside of the swivel 203, and a dredging component 205 disposed on one side of the anti-blocking component 204;

[0042] The filter unit 300 includes a connecting rod 301 disposed inside the rotating ring 203 , a scraper 302 disposed on one side of the connecting rod 301 , a filter screen 303 disposed on one side of the scraper 302 , and a filter tank 304 disposed at the bottom of the filter screen 303 .

[0043] Furthermore, the slurry box 101 includes a slurry outlet pipe 101a disposed outside the slurry box 101, a slurry pool 101b disposed inside the slurry outlet pipe 101a, an outer wall 101c disposed outside the slurry pool 101b, and an inner wall 101d disposed inside the slurry pool 101b.

[0044] The water collecting tank 105 includes a water outlet pipe 105a disposed outside thereof;

[0045] The filter tank 304 includes a water filter pipe 304a disposed at the bottom thereof.

[0046] Furthermore, the shaft coupling 202 includes a rotary bearing 202a fixedly disposed on the inner side of the outer gear ring 201 and an inner gear ring 202b disposed on the inner side of the rotary bearing 202a.

[0047] Further, the rotating ring 203 is fixedly connected to the inner gear ring 202b;

[0048] It should be noted that if Figure 1 and Figure 2As shown, the slurry box 101 is a circular ring structure, and the bottom plate is inclined, so that the gypsum slurry that has been dehydrated at the bottom can be discharged easily. A plurality of groups of cyclones 102 are arranged in a circular array on the top of the slurry box 101. The cyclone 102 is a prior art that can effectively utilize the rotating vortex to dehydrate the gypsum slurry. The liquid inlet pipe 103 is connected to the liquid inlet end of the cyclone 102 through an adjusting pump flange. A group of liquid outlet pipes 104 are connected to the flange on the other side of the end of each group of cyclones 102. The liquid outlet pipe 104 can discharge the water in the gypsum slurry. The other end of the liquid outlet pipe 104 is connected to the top of the water collecting tank 105, which is used to collect dewatering. The water collecting tank 105 is also arranged in a ring on the outside of the cyclone 102 for easy integrated arrangement.

[0049] Better, such as Figure 2 and Figure 4 As shown, a group of outer gear rings 201 are slidably engaged on the outer side of the slurry box 101, and the outer gear rings 201 are arranged through the inner side of the outer wall 101c of the slurry box 101, so as to provide power for the anti-blocking unit 200 and the filter unit 300 arranged on the inner side of the slurry box 101. The rotary bearing 202a is engaged on the inner side of the outer wall 101c through the ball bearing to reduce the friction with the outer wall 101c. And the rotary bearing 202a can be fixedly connected to the inner side of the outer gear ring 201 by welding or the like. Similarly, a group of rotary bearings 202a are welded on the inner side of the rotary bearing 202a. In other words, when the outer gear ring 201 rotates, it can drive the rotary bearing 202a and the inner gear ring 202b to rotate. A set of rotating rings 203 are also fixedly connected to the bottom of the inner gear ring 202b. The rotating rings 203 are tightly slidably fitted on the inner side of the outer wall 101c. The outer gear ring 201 can drive the rotating rings 203 to rotate when driven by an external motor.

[0050] Better, such as Figure 4 As shown, the swivel 203 is a double-ring structure, the outer ring of which is slidably fitted on the outer wall 101c, and the inner ring is slidably sleeved on the inner wall 101d, and the swivel 203 is fixedly connected together by a connecting rod 301 welded on the inner side thereof. An elastic scraper 302 is welded on the outer side of the connecting rod 301, and the scraper 302 is always set downward, which is conducive to the rapid discharge of the dehydrated gypsum slurry under the push of the scraper 302, reducing the accumulation of gypsum slurry in the slurry pool 101b, causing the entire unit to be blocked. In addition, a group of annular filter screens 303 are clamped at the bottom of the slurry pool 101b to filter the dehydrated gypsum slurry again to increase the concentration of the gypsum slurry.

[0051] When in use, the staff drives the outer gear ring 201 to rotate by using an external motor or other equipment, pumps the gypsum slurry into the cyclone 102 through the liquid inlet pipe 103, and the gypsum slurry is quickly dehydrated under the cyclone separation of the cyclone 102. The dehydrated water will be discharged from the outlet pipe 105a, and the remaining gypsum slurry will be discharged from the bottom of the cyclone 102 and flow into the slurry pool 101b. The fluidity of the gypsum slurry itself and the rotation of the rotating ring 203 driven by the outer gear ring 201 can indirectly drive the scraper 302 in the middle of the rotating ring 203 to rotate, thereby improving the fluidity of the gypsum slurry at the bottom of the slurry pool 101b and the passability of the secondary filtration water, and preventing the gypsum slurry from settling and causing blockage.

[0052] In summary, with the setting of the dehydration unit 100, the anti-blocking unit 200 and the filtering unit 300, the device can achieve effective dehydration of the gypsum slurry, and utilizes the outer gear ring 201 to drive the rotating ring 203 to rotate, thereby indirectly driving the scraper 302 in the middle of the rotating ring 203 to rotate, thereby improving the fluidity of the gypsum slurry at the bottom of the sedimentation tank 101b and the permeability of the secondary filtration water, avoiding the sedimentation of the gypsum slurry and causing blockage, and further improving the solid-liquid separation effect of the gypsum slurry, thereby increasing the concentration of the gypsum slurry.

[0053] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: the rotating ring 203 also includes an annular groove 203a penetratingly arranged on the inner side thereof;

[0054] The anti-blocking assembly 204 includes a plurality of gears 204a meshing with the inner gear ring 202b, and a plurality of gears 204a disposed on the gears 204a.

[0055] The upper support frame 204 b and the sleeve 204 c arranged at the bottom of the cyclone 102 .

[0056] Furthermore, the clearing component 205 includes a sliding rod 205a slidably connected to the annular groove 203a, a connecting piece 205b arranged on the inner side of the sliding rod 205a, a ring 205c arranged on the inner side of the connecting piece 205b, and a clearing piece 205d arranged at the bottom of the sleeve 204c.

[0057] Furthermore, the support frame 204b includes a clamping plate 204b-1 movably clamped on the inner side of the gear 204a, and a support plate 204b-2 disposed above the clamping plate 204b-1;

[0058] The sleeve 204 c is movably sleeved on the bottom of the cyclone 102 .

[0059] Furthermore, the sleeve 204c includes a scraper rod 204c-1 disposed on the top thereof, a vertical groove 204c-2 disposed on the outside of the sleeve 204c, and a horizontal groove 204c-3 disposed on the bottom of the sleeve 204c;

[0060] The vertical slot 204c-2 is fixedly engaged with the gear 204a.

[0061] Furthermore, the connecting member 205b includes a vertical plate 205b-1 disposed inside the sliding rod 205a, a horizontal plate 205b-2 disposed on one side of the vertical plate 205b-1, and a through hole 205b-3 disposed inside the horizontal plate 205b-2;

[0062] The through hole 205b-3 is slidably connected to the outside of the sleeve 204c.

[0063] Furthermore, the clearing member 205d includes a pressure plate 205d-1 arranged at the bottom of the sleeve 204c, a fixing ear 205d-2 fixedly arranged on the inner side of the horizontal plate 205b-2, a connecting block 205d-3 arranged at the rear end of the pressure plate 205d-1, a clamping ring 205d-4 arranged on one side of the connecting block 205d-3, and a spring 205d-5 arranged on the inner side of the connecting block 205d-3.

[0064] Further, the connecting block 205d-3 includes a slide groove 205d-31 disposed on the inner side thereof;

[0065] The clamping ring 205d-4 includes two groups of connecting posts 205d-41 disposed on one side of the slide groove 205d-31, and a U-shaped ring 205d-42 on one side of the connecting posts 205d-41;

[0066] The clamping ring 205d-4 is slidably connected to the end surface of the transverse plate 205b-2; and the U-shaped ring 205d-42 cooperates with the transverse groove 204c-3.

[0067] It should be noted that if Figure 4 As shown, the structure of the dehydration unit 100 and the outer gear ring 201 is the same as that of the first embodiment. A circle of annular wave-shaped annular groove 203a is set on the inner side of the rotating ring 203, and the annular groove 203a does not divide the rotating ring 203 into two independent structures to prevent the bottom of the rotating ring 203 from being unable to rotate. The annular groove 203a provides a force for the dredging member 205d to move up and down, so as to poke through the bottom mouth of the cyclone 103 and prevent the cyclone 102 from being blocked.

[0068] Better, such as Figure 3 As shown, a set of gears 204a is sleeved on the outer side of the bottom mouth of each set of cyclones 102, and a set of support frames 204b are set above the gears 204a, and the support frames 204b provide a suspension force for the gears 204a. When the inner gear ring 202b is driven to rotate by the outer gear ring 201, the gear 204a meshed with the inner side of the inner gear ring 202b will also rotate. Figure 5As shown, a set of sleeves 204c is slidably sleeved inside the bottom mouth of the cyclone 102, and the sleeves 204c are embedded in the pipe mouth of the cyclone 102, and do not affect the normal cyclone effect of the cyclone 102. Multiple groups of scrapers 204c-1 with equal spacing are welded on the circumference of the pipe mouth above the sleeve 204c, and the scrapers 204c-1 are turned outward and have a certain elasticity, so that they can fit tightly on the inner wall of the cyclone 102. A vertical groove 204c-2 is opened on the outer wall of the sleeve 204c, and the vertical groove 204c-2 is slidably engaged in the keyway of the gear 204a. When the gear 204a is driven to rotate by the inner gear ring 202b, the sleeve 204c will also rotate with the gear 204a sleeved on the outside.

[0069] Better, such as Figure 5 As shown, a circle of card slots is provided on the end face of the gear 204a, which can be slidably connected with the card plate 204b-1. Similarly, a group of support plates 204b-2 are fixedly welded on the upper end face of the card plate 204b-1, one side of the support plate 204b-2 slides on the upper end face of the inner gear ring 202b, and the other side is on the upper end face of the ring 205c. When the gear 204a is driven to rotate by the inner gear ring 202b, the support frame 204b can limit the gear 204a. As the sleeve 204c rotates with the gear 204a sleeved on the outside, the multiple groups of scraper rods 204c-1 above the sleeve 204c will also rotate with the sleeve 204c, which is convenient for scraping off the gypsum slurry attached to the inner wall of the bottom of the cyclone 102, reducing the accumulation of gypsum slurry at the pipe mouth of the cyclone 102, causing the cyclone 102 to be blocked, and reducing the gypsum slurry hanging on the wall.

[0070] Better, such as Figure 4As shown, the annular groove 203a provides a force for the clearing member 205d to move up and down, so as to poke through the bottom mouth of the cyclone 103 and avoid clogging of the cyclone 102. Among them, a group of sliding rods 205a are slidably arranged on the inner side of the annular groove 203a. When the annular groove 203a rotates with the rotating ring 203, the sliding rod 205a can move up and down along the track of the annular groove 203a. In addition, a group of connecting members 205b are welded on the inner side of the sliding rod 205a. The connecting member 205b is composed of a vertical plate 205b-1 fixedly welded to the sliding rod 205a, a horizontal plate 205b-2 at the upper end of the vertical plate 205b-1, and a through hole 205b-3 on the inner side of the horizontal plate 205b-2. The sliding rod 205a and the connecting member 205b are an integrated structure. The plurality of groups of horizontal plates 205b-2 arranged in a circular array outside the sleeve 204c are all slidably connected to the collar 205c, which restricts the movement of the connecting member 205b, so that it can only move up and down, and the collar 205c is welded to the inner wall 101d. A sliding groove is provided at the position corresponding to the horizontal plate 205b-2 on the collar 205c, which allows the horizontal plate 205b-2 to move up and down.

[0071] Better, such as Figure 5 As shown, the sleeve 204c is slidably sleeved in the through hole 205b-3 on the inner side of the horizontal plate 205b-2. When the sleeve 204c rotates, the through hole 205b-3 on the outer side thereof does not restrict the rotation of the sleeve 204c. The vertical slot 204c-2 on the outer side of the sleeve 204c does not hinder the up and down movement of the horizontal plate 205b-2.

[0072] Better, such as Figure 6 As shown, a group of dredging pieces 205d are arranged at the bottom of each group of sleeves 204c, and the dredging pieces 205d can sense the flow rate of the gypsum slurry from the sleeves 204c, thereby driving the dredging pieces 205d to dredge the bottom of the cyclone 102. The dredging pieces 205d are composed of a pressure plate 205d-1, a fixed ear 205d-2 fixedly connected to the hole of the through hole 205b-3, a connecting block 205d-3 fixedly connected to one side of the pressure plate 205d-1, a clamping ring 205d-4 movably embedded in the inner side of the cross plate 205b-2, and a spring 205d-5 inside the connecting block 205d-3. The fixed ear 205d-2 is fixedly connected to the hole wall of the through hole 205b-3. The fixing ear 205d-2 extends downwardly and is provided with a hinge rod, on which a group of pressure plates 205d-1 are hinged, and the pressure plates 205d-1 are just arranged at the bottom of the pipe opening of the sleeve 204c. There is a certain distance between the pressure plates 205d-1 and the sleeve 204c, and this distance can ensure that when the pressure plates 205d-1 follow the horizontal plate 205b-2 to move up and down, they will not cause movement interference to the sleeve 204c.

[0073] Better, such as Figure 7 As shown, the pressure plate 205d-1 and the connecting block 205d-3 are an integral structure. The connecting block 205d-3 is composed of two plates fixedly connected to the rear side of the pressure plate 205d-1. A pipe diameter larger than the sleeve 204c is left between the two groups of connecting blocks 205d-3, which is convenient for connecting the U-shaped ring 205d-42 outside the sleeve 204c. In addition, two groups of sliding grooves 205d-31 are set through the inner side of the connecting block 205d-3 plate body, and a group of clamping rings 205d-4 are slidably connected inside the sliding grooves 205d-31. The clamping ring 205d-4 is composed of two groups of connecting columns 205d-41 slidably connected inside the sliding grooves 205d-31, and U-shaped rings 205d-42 outside the two groups of connecting columns 205d-41. The U-shaped ring 205d-42 is slidably embedded in the end surface of the horizontal plate 205b-2. In addition, a circle of horizontal grooves 204c-3 is provided at the bottom of the sleeve 204c. When the U-shaped ring 205d-42 moves forward, it can be clamped in the horizontal groove 204c-3 of the sleeve 204c, so that the horizontal plate 205b-2 can drive the sleeve 204c to move up and down, and clear the gypsum slurry accumulated at the cyclone 102 tube. At the same time, a group of springs 205d-5 are also slidably connected in the chute 205d-31. One end of the spring 205d-5 is slidably connected to the inner side of the chute 205d-31, and the other end is fixedly connected to the inner wall of the horizontal plate 205b-2. The spring 205d-5 can provide power for the reset of the pressure plate 205d-1. When the cyclone 102 works normally and the gypsum slurry flow is in a normal state, the gypsum slurry falls onto the pressure plate 205d-1 through the sleeve 204c, and the pressure plate 205d-1 rotates downward to stretch the spring 205d-5 inside the slide groove 205d-31 outward to detect the gypsum slurry flow state.

[0074] The other structures are the same as those in Example 1.

[0075] When in use, the staff uses an external motor or other equipment to drive the outer gear ring 201 to rotate, and the outer gear ring 201 will drive the inner gear ring 202b and the rotating ring 203 to rotate. The rotation of the inner gear ring 202b will drive the gear 204a meshing on its inner side to rotate, and at the same time, the annular groove 203a on the rotating ring 203 rotates. There are two different working states under the rotation of the annular groove 203a and the rotation of the gear 204a.

[0076] First, when the flow state of the gypsum slurry inside the cyclone 102 is normal: when the gear 204a rotates, the multiple groups of scraper rods 204c-1 above the sleeve 204c will also rotate with the sleeve 204c, so as to scrape off the gypsum slurry attached to the inner wall at the bottom of the cyclone 102, reduce the accumulation of gypsum slurry at the mouth of the cyclone 102, cause the cyclone 102 to be blocked, and reduce the gypsum slurry hanging on the wall. In this process, the rotating ring 203 at the bottom of the inner gear ring 202b will also rotate at the same time, and the sliding rod 205a and the connecting piece 205b on the annular groove 203a will also move up and down along the track of the annular groove 203a without stopping, which can prevent the gypsum slurry from adhering to the additional rotating ring 203. After that, the horizontal plate 205b-2 will also move up and down with the dredging piece 205d, and will not drive the sleeve 204c to move up and down, thereby reducing the wear of the sleeve 204c in the cyclone 102. The gypsum slurry flowing through the sleeve 204c falls onto the pressure plate 205d-1. Under the hinged action of the fixed ear 205d-2, the pressure plate 205d-1 always has a tendency to rotate downward, and the connecting block 205d-3 on the other side of the fixed ear 205d-2 rotates upward, pushing the U-shaped ring 205d-42 outward, preventing the U-shaped ring 205d-42 from being stuck in the transverse groove 204c-3, and continuously stretching the spring 205d-5 on the inside of the slide groove 205d-31 outward to detect the flow state of the gypsum slurry.

[0077] Secondly, when the flow state of the gypsum slurry inside the cyclone 102 is abnormal: at this time, the scraper rod 204c-1 and the cross plate 205b-2 are constantly moving, but the gypsum slurry flow is reduced due to the blockage of the cyclone 102, and the tension on the spring 205d-5 is reduced, and it begins to retract. The spring 205d-5 pulls the connecting block 205d-3 downward and rotates it, and pulls the U-shaped ring 205d-42 inward, so that the U-shaped ring 205d-42 is clamped in the transverse groove 204c-3, so that the sleeve 204c moves up and down with the cross plate 205b-2 under the action of the transverse groove 204c-3, and the sleeve 204c and the scraper rod 204c-1 move up and down to dredge the cyclone 102. After dredging, when the gypsum slurry flow increases, the pressure plate 205d-1 is pressed down to detect the gypsum slurry flow state again to avoid blockage of the cyclone 102.

[0078] In summary, the device, with the arrangement of the dehydration unit 100, the anti-blocking unit 200 and the filtering unit 300, realizes the effective dehydration of the gypsum slurry. Under normal flow, the gear 204a drives the scraper 204c-1 to remove the gypsum slurry on the inner wall of the cyclone 102 to reduce accumulation. The annular groove 203a on the swivel 203 cooperates with the slide bar 205a and the connector 205b to prevent the gypsum slurry from adhering to the swivel. The up and down movement of the horizontal plate 205b-2 and the dredging member 205d avoids the wear of the sleeve 204c, and the pressure plate 205d-1 maintains the state of detecting the flow of the gypsum slurry under the action of the fixed ear 205d-2. When the flow is abnormal, the rebound of the spring 205d-5 triggers the U-shaped ring 205d-42 to snap into the transverse groove 204c-3, achieving synchronous movement of the sleeve 204c and the transverse plate 205b-2, and automatically clearing the cyclone 102. As the flow is restored, the pressure plate 205d-1 is pressed down to re-detect and maintain the cyclone 102 unblocked.
