Description

Technical Field

[0001] The present application relates to the field of sewage treatment equipment, and in particular to an intelligent high-pressure belt-type deep dehydrator and a control method thereof. Background Art

[0002] The sludge produced by sewage treatment has a high water content. Dehydration of the sludge can significantly reduce the volume and weight of the sludge, thereby reducing the cost of subsequent treatment and disposal. At the same time, dehydration can reduce the moisture content of the sludge and reduce the degradation rate of organic matter, thereby improving the stability of the sludge. Commonly used sludge dehydration equipment generally includes belt dehydrators, centrifugal dehydrators and plate and frame dehydrators. Belt dehydrators are widely used due to their low operating costs and high desludge efficiency.

[0003] A high-pressure crawler type dehydrator is disclosed in a Chinese patent document with the announcement number CN220056612U, and specifically discloses a mounting frame and a supporting frame, on which a crawler cleaning mechanism and a feeding mechanism for evenly distributing materials are installed, the feeding mechanism comprises a feeding assembly, a conveying roller, a conveying frame, a distributing assembly and a spreading plate, the inner cavity top of the distributing assembly is connected with a spreading plate, the spreading plate is triangular, the supporting frame is located at one end of the mounting frame, and a first crawler mechanism and a second crawler mechanism are installed on the supporting frame. Through the coordinated use of the first crawler mechanism and the second crawler mechanism, the upper filter belt is attached to the lower filter belt, and on the basis of the rotation of the lower filter belt and the upper filter belt, the lower filter belt and the upper filter belt are squeezed, thereby dehydrating the sludge between the lower filter belt and the upper filter belt.

[0004] Although the above patent uses a spreading plate to push the sludge in the middle of the lower filter belt to both sides, and the spreading plate is spaced a certain distance from the surface of the lower filter belt, so that the sludge is evenly spread to avoid sludge accumulation affecting subsequent dehydration, the spreading plate is fixed and has a single structure, and cannot be adaptively adjusted for sludge with different water contents or different operating speeds of the dehydrator. There are still problems such as poor spreading effect, easy sludge accumulation, and easy damage to the filter belt. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present application provides an intelligent high-pressure belt-type deep dehydrator and a control method thereof.

[0006] In the first aspect, the present application provides an intelligent high-pressure belt deep dehydrator, which is implemented by the following technical solution:

[0007] An intelligent high-pressure belt deep dehydrator comprises a frame and an upper filter belt and a lower filter belt arranged on the frame, a feeding area is provided on one side of the frame and a discharging area is provided on the other side, and a cloth mechanism is also provided on the frame, and the cloth mechanism is arranged in the feeding area. The cloth mechanism comprises a fixed plate, a movable plate and a connecting plate, and the connecting plate is used to connect the fixed plate and the movable plate, and the connecting plate is flexible, and the movable plate can rotate around the connecting plate; the fixed plate and the movable plate are both arranged between the upper filter belt and the lower filter belt and are both inclined, and the angle between the fixed plate and the lower filter belt is smaller than the angle between the movable plate and the lower filter belt.

[0008] By adopting the above technical scheme, in the process of the cloth mechanism spreading the sludge evenly on the lower filter belt, the inclined fixed plate will play a major role in spreading the sludge, and the movable plate will play a role in shielding the splashed or surging sludge, and the movable plate and the fixed plate are connected by a flexible connecting plate, so that the angle between the movable plate and the lower filter belt can be adjusted. In this way, when the operating speed of the dewatering machine (i.e., the rotation speed of the upper filter belt and the lower filter belt) is faster, the angle between the movable plate and the lower filter belt is larger, so that more sludge can be accommodated between the movable plate and the lower filter belt. In other words, the amount of sludge waiting to enter between the fixed plate and the lower filter belt becomes larger, thereby leaving more time for the fixed plate to spread the sludge already between the fixed plate and the lower filter belt. While ensuring that the sludge is spread evenly, it is effectively prevented that when the amount of sludge increases instantly, the fixed plate cannot be spread in time, causing the sludge to overflow from the lower filter belt, and the extrusion strength between the fixed plate and the sludge is reduced, effectively improving the service life of the lower filter belt and the upper filter belt.

[0009] Optionally, a rotating seat is provided on the top of the movable plate, and a vertical plate is provided on the top of the fixed plate, the vertical plate is connected to the frame and is used to fix the fixed plate, an adjusting rod is passed between the vertical plate and the rotating seat, one end of the adjusting rod is sleeved on the rotating seat, the other end of the adjusting rod passes through the vertical plate, and the other end of the adjusting rod is threadedly connected to a nut, and the nut is in contact with a side of the vertical plate away from the rotating seat.

[0010] By adopting the above technical solution, the movable plate is always in an inclined state. Under the action of gravity, the movable plate will pull the adjusting rod to move in the direction of the movable plate, so that the nut can always maintain a state of being in contact with the vertical plate; further, by adjusting the position of the nut on the adjusting rod, the pulling effect on the adjusting rod can be achieved, and the adjusting rod can be rotated on the rotating seat, so that when the adjusting rod produces a horizontal displacement, it can form a pulling effect on the movable plate, thereby achieving the adjustment of the angle of the movable plate.

[0011] Optionally, a through hole is provided on the vertical plate, and the adjusting rod passes through the vertical plate through the through hole. The inner diameter of the through hole is larger than the outer diameter of the adjusting rod, and the outer diameter of the nut is larger than the inner diameter of the through hole.

[0012] By adopting the above technical solution, the inner diameter of the through hole is larger than the outer diameter of the adjusting rod, so that the adjusting rod can produce radial string movement, ensuring that the movable plate can be pulled by the adjusting rod, and the outer diameter of the nut is larger than the inner diameter of the through hole, ensuring that the nut will not penetrate into the through hole, ensuring that the adjustment and limiting effects of the nut are reliable.

[0013] Optionally, a sleeve and an annular pressure sensor are provided on the side of the vertical plate facing away from the nut, the sleeve, the pressure sensor and the perforation are all coaxially arranged, and the pressure sensor is arranged on the inner side of the sleeve; a pressing plate and a plurality of pressure rods are provided in the sleeve, and the plurality of pressure rods are arranged at intervals along the same circumference, one end of the pressure rod is connected to the pressing plate, and the other end of the pressure rod abuts against the pressure sensor, and a limit plate and a spring are provided on the adjusting rod, one end of the spring is connected to the limit plate, and the other end is connected to the pressing plate; the adjusting rod is fixedly connected to the limit plate, the adjusting rod passes through the pressure plate and the pressure sensor, and there are gaps between the adjusting rod and the pressure plate and between the adjusting rod and the pressure sensor, a controller is provided on the frame, and there is an electrical connection between the pressure sensor and the controller, the pressure sensor is used to collect the pressure value of the movable plate, and the controller is used to collect and analyze the pressure values ​​collected by the pressure sensor and control the feeding speed and the rotation speed of the upper filter belt and the lower filter belt.

[0014] By adopting the above technical solution, the limit plate and the adjusting rod cannot move relative to each other, while the pressure plate and the adjusting rod can move relative to each other. In this way, when the amount of sludge input into the feed zone suddenly increases during the dehydration process of the dehydrator, the sludge will push the movable plate, so that the distance between the movable plate and the lower filter belt increases, which will also cause the adjusting rod to move horizontally. When the adjusting rod moves toward the nut driven by the movable plate, the limit plate will approach the sleeve, the spring will be compressed, and the pressure generated by the spring compression will be transmitted to the pressure sensor through the pressure plate and the pressure rod. That is to say, when the feed amount (i.e., the sludge input amount) suddenly increases, the pressure value collected by the pressure sensor will increase. Naturally, when the feed amount is restored, the pressure value collected by the pressure sensor will also decrease to the initial state. When the pressure value collected by the pressure sensor is in a large state for a long time, the controller will reduce the feed speed or increase the rotation speed of the upper filter belt and the lower filter belt, so as to ensure that the fixed plate can stably spread the sludge.

[0015] Optionally, a feeding mechanism is provided on the top of the frame, and the feeding mechanism includes a hopper and a filtering unit. The hopper is connected to the frame by a bracket, and a feeding pipe is provided at one end of the hopper and a discharging pipe is provided at the other end, and the discharging pipe is located above the feeding area. The filtering unit is arranged in the hopper, and the discharging end of the feeding pipe is located above the filtering unit, and the feeding end of the discharging pipe is located below the filtering unit. The filtering unit is used to filter large particles in the sludge.

[0016] By adopting the above technical solution, after the feed pipe discharges the sludge, the sludge will fall into the filter unit, and after passing through the filter unit, it will be discharged from the hopper through the discharge pipe and fall into the feed area. Under the filtering action of the filter unit, large particles entrained in the sludge will be intercepted, which can prevent the large particles from moving between the lower filter belt and the lower filter belt, causing damage to the upper filter belt or the lower filter belt under the squeezing action of the upper filter belt and the lower filter belt, and further extend the service life of the upper filter belt and the lower filter belt.

[0017] Optionally, the filter unit includes a first filter frame and a second filter frame, and the first filter frame and the second filter frame are each provided with a filter plate, and the first filter frame and the second filter frame are aligned in the horizontal direction and fit with the inner wall of the hopper; a first mounting frame and a second mounting frame are provided on the top of the hopper, and a winch is provided on the first mounting frame and the second mounting frame, one winch is used to lift the first filter frame, and the other winch is used to lift the second filter frame, and a tension sensor is provided on the lifting rope of the two winches, and the tension sensor and the controller are electrically connected, and the tension sensor is used to collect the tension value of the lifting rope, and the controller is also used to collect and analyze the tension value collected by the tension sensor and control the feeding speed and the rotation speed of the winch.

[0018] By adopting the above technical scheme, the first filter frame and the second filter frame can form a truncation of the hopper after being laid flat and aligned, that is, the first filter frame is in contact with the hopper, and the first filter frame is also in contact with the hopper. In this way, after the sludge is discharged from the feed pipe, it must pass through the filter plate in the first filter frame or the filter plate in the second filter plate before it can flow to the lower part of the hopper, that is, the sludge can be reliably filtered by the filter plate; when the feed amount remains stable, the tension values ​​collected by the two tension sensors are also maintained within a preset range, and when too many large particles are retained on the filter plate, the overall weight of the first filter frame and the second filter frame will increase, so that the tension value collected by the tension sensor will also increase and exceed the preset value. At this time, the controller can start the two winches at the same time, so that the first filter frame and the second filter frame can move upward synchronously, so that it is convenient for the staff to remove the large particles on the two filter plates, thereby avoiding clogging of the filter plates due to excessive large particles.

[0019] Optionally, the first filter frame is close to the feed pipe, the width of the first filter frame is smaller than the width of the second filter frame, a baffle is provided on the first mounting frame, the baffle is located above the first filter frame and close to the second filter frame, a pair of limit bars are provided on the second mounting frame, the limit bars interfere with the second filter frame in the vertical direction, the pair of limit bars are inclined and parallel to each other, the height of one end of the limit bar close to the discharge pipe is lower than the height of one end of the limit bar close to the feed pipe; a material guide plate is provided on the top of the hopper, when the second filter frame is in contact with the limit bar, the second filter frame is in an inclined state and the height of the second filter frame is higher than the height of the material guide plate, a material guide groove is provided on the outside of the hopper, the material guide groove is in an inverted V shape, the material guide groove is located below the material guide plate, and both ends of the material guide groove are located on the outside of the frame.

[0020] By adopting the above technical solution, when the first filter frame contacts the baffle, the first filter frame stops moving up and becomes horizontal, and when the second filter frame fits the limit strip, the second filter frame stops moving up and becomes inclined. At this time, the height of the second filter frame is higher than that of the first filter frame, and under the shielding effect of the baffle, the sludge will not move toward the second filter frame. That is to say, at this time, the sludge can and all be filtered through the filter plate in the first filter frame, and no new sludge will enter the second filter frame. The filter frame in the second filter frame can be efficiently cleaned, which significantly improves the cleaning efficiency and prevents the sludge from flowing everywhere during the cleaning process. Furthermore, the height of the second filter frame is higher than the height of the guide plate, and a guide groove is provided at the end of the guide plate. After the staff pushes the large particles on the filter plate onto the guide plate, the large particles can slide along the guide plate into the guide groove, and then slide down through the guide groove. Recovery bins can be provided under the two ends of the guide groove, thereby realizing automatic collection of the swept large particles, reducing the difficulty of cleaning the filter plate and improving the cleaning efficiency.

[0021] Optionally, the guide plate is arranged on one side of the top of the hopper, and a numerically set extension plate is provided on the other side of the top of the hopper, and the feed pipe is provided on the extension plate; the first filter frame and the second filter frame are arranged on the upper inner side of the hopper, and a third filter frame is provided on the lower inner side of the hopper, and a filter plate is also provided on the inner side of the third filter frame, and the third filter frame is located above the feed end of the discharge pipe, and the third filter frame is separated from the first filter frame and the second filter frame in the vertical direction; the bottom of the baffle is located on the inner side of the hopper, and the top of the baffle is located on the outer side of the hopper, and when the first filter frame is in contact with the baffle and the second filter frame is in contact with the limit strip, the first filter frame and the second filter frame are in a state of up and down misalignment.

[0022] By adopting the above technical solution, the third filter frame and the filter plate arranged in the third filter frame can play the role of standby filtering, that is, during the cleaning process of the filter plates in the first filter frame and the second filter frame, a small amount of unfiltered sludge will fall onto the filter plate in the third filter frame, ensuring that all sludge can be filtered at least once. Furthermore, since the third filter frame is separated from the first filter frame and the second filter frame in the vertical direction, the tension value collected by the tension sensor can accurately reflect the weight of the first filter frame or the second filter frame.

[0023] Optionally, a pair of tensioning mechanisms are also provided in the frame, and the tensioning mechanism includes a movable rod, a tensioning roller and an adjusting cylinder, one end of the movable rod is movably connected to the frame, the other end of the movable rod is movably connected to the push rod of the adjusting cylinder, the cylinder body of the adjusting cylinder is movably connected to the frame, the tensioning roller is installed on the movable rod, and the adjusting cylinder is used to adjust the rotation angle of the movable rod; the upper filter belt is wound around the tensioning roller of one of the tensioning mechanisms, and the lower filter belt is wound around the tensioning roller of another of the tensioning mechanisms.

[0024] By adopting the above technical solution, under the push of the adjusting cylinder, the movable rod will rotate at a certain angle, so that the tension of the upper filter belt or the lower filter belt can be adjusted, and then the distance between the upper filter belt and the lower filter belt can be adjusted, thereby realizing the adjustment of the squeezing force of the upper filter belt and the lower filter belt on the sludge, which is convenient for achieving deep dehydration of the dehydrator.

[0025] In the second aspect, the present application provides a control method for an intelligent high-pressure belt-type deep dehydrator, which is implemented by the following technical solution:

[0026] The control method of the intelligent high-pressure belt-type deep dehydrator comprises the following steps:

[0027] S1. Turn the nut to adjust the angle between the movable plate and the lower filter belt to 30°-35°. The controller controls the two winches to synchronously lower the first filter frame and the second filter frame to the inner lower part of the hopper, and the distance between the first filter frame and the third filter frame is 5-10 cm.

[0028] S2. The controller controls the upper filter belt and the lower filter belt to rotate synchronously. At the same time, the feed pipe transports the sludge into the hopper. The sludge passes through the filter plate and is transported to the feed area through the discharge pipe and falls between the upper filter belt and the lower filter belt. The dehydrated sludge is discharged from the discharge area. The process is completed.

[0029] In step S2, when the pressure value collected by the pressure sensor is greater than the set value, the controller reduces the feed speed or increases the rotation speed of the upper filter belt and the lower filter belt;

[0030] In step S2, when the tension value collected by the tension sensor is greater than the set value, the controller reduces the feed speed or controls the winch to start, and the winch pulls the first filter frame and the second filter plate upwards, thereby removing large particles trapped on the filter plates.

[0031] By adopting the above technical solutions, the pressure sensor can monitor the pressure condition of the movable plate, the tension sensor can monitor the tension condition of the hoisting rope of the winch, and the controller can automatically and intelligently adjust the operating speed of the dewatering machine or the sludge feed amount according to the data collected by the pressure sensor and the tension sensor, thereby improving the sludge dewatering effect while extending the service life of the upper filter belt and the lower filter belt.

[0032] Compared with the prior art, this application has the following beneficial effects:

[0033] 1. A cloth mechanism is arranged between the upper filter belt and the lower filter belt, which can reliably and evenly spread the sludge on the lower filter belt. Furthermore, the extrusion pressure from the sludge on the movable plate is monitored by a pressure sensor. When the extrusion pressure is too large, the controller can automatically identify and quickly and accurately adjust the rotation speed of the upper filter belt and the lower filter belt, and can also adjust the sludge feed amount, so as to ensure that the sludge will not accumulate between the upper filter belt and the lower filter belt, thereby ensuring that the sludge is dehydrated under the extrusion of the upper filter belt and the lower filter belt, and avoiding the damage to the upper filter belt and the lower filter belt caused by the accumulated sludge, thereby extending the service life of the upper filter belt and the lower filter belt.

[0034] 2. A feeding mechanism is arranged on the top of the frame, and the feeding mechanism includes a hopper and a filtering unit. After the feeding pipe on the hopper inputs sludge into the hopper, the filtering unit will filter the sludge, thereby intercepting large particles entrained in the sludge. The filtered sludge is discharged into the feeding area through the discharge pipe, which effectively prevents large particles from entering between the upper filter belt and the lower filter belt, and significantly improves the protection effect of the upper filter belt and the lower filter belt.

[0035] 3. The first filter frame and the second filter frame are hoisted respectively by two winches, so that the first filter frame remains horizontal after lifting and the second filter frame becomes inclined after lifting. In this way, the filter plate in the first filter frame can still perform filtering operations, while the filter plate in the second filter frame is lifted to a higher position, which is convenient for the staff to quickly and conveniently clean the filter plate in the second filter frame, ensuring that the filter plate can reliably filter the sludge.

[0036] 4. The tension of the upper filter belt and the lower filter belt can be adjusted respectively through two tensioning mechanisms. While ensuring that the upper filter belt and the lower filter belt can rotate reliably, the distance between the upper filter belt and the lower filter belt can be adjusted, thereby adjusting the squeezing force of the sludge between the upper filter belt and the lower filter belt. While ensuring that the upper filter belt and the lower filter belt are not damaged, the squeezing force on the sludge is increased to the greatest extent to achieve deep dehydration.

[0052] Below, combined with the attached Figure 1-8 As well as specific implementation methods, the present application is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0053] This embodiment discloses an intelligent high-pressure belt-type deep dehydrator.

[0054] Figure 1 is a schematic three-dimensional diagram of the present application, Figure 2 This is a reference diagram of the winding state of the upper filter belt and the lower filter belt on the frame, where: Figure 2 The feed mechanism 4 is removed. Figure 1 and Figure 2The intelligent high-pressure belt deep dehydrator includes a frame 1 and an upper filter belt 21 and a lower filter belt 22 arranged on the frame 1. A feeding area 11 is provided on one side of the frame 1, and a discharging area 12 is provided on the other side. The sludge enters between the upper filter belt 21 and the lower filter belt 22 through the feeding area 11, and completes the dehydration operation under the squeezing action of the rotating upper filter belt 21 and the lower filter belt 22. A pair of tensioning mechanisms 5 are also provided in the frame 1. The tensioning mechanism 5 includes a movable rod 51, a tensioning roller 52 and an adjusting cylinder 53. One end of the movable rod 51 is movably connected to the frame 1, and the other end of the movable rod 51 is movably connected to the push rod of the adjusting cylinder 53. The cylinder body of the adjusting cylinder 53 is movably connected to the frame 1. The tensioning roller 52 is installed on the movable rod 51. The adjusting cylinder 53 is used to adjust the rotation angle of the movable rod 51. The upper filter belt 21 is wound on the tensioning roller 52 of one tensioning mechanism 5, and the lower filter belt 22 is wound on the tensioning roller 52 of another tensioning mechanism 5. At the same time, a plurality of staggered The installation roller 14 is set, and the cooperation of several installation rollers 14 and tensioning roller 52 can realize the reliable rotation of the upper filter belt 21 and the lower filter belt 22. At the same time, when the adjusting cylinder 53 drives the movable rod 51 to rotate, the position of the tensioning roller 52 can be changed while the position of the installation roller 14 remains fixed. In this way, the tension of the upper filter belt 21 and the lower filter belt 22 can be adjusted respectively by the two tensioning mechanisms 5. Moreover, with the changes in the tension and position of the upper filter belt 21 and the lower filter belt 22, the squeezing force of the upper filter belt 21 and the lower filter belt 22 on the sludge can be adjusted, thereby realizing deep dehydration of the sludge.

[0055] Furthermore, two deviation correction limit units 6 and an over-limit unit 7 are provided on the frame 1. A pair of deviation correction limit units 6 are located on the outside of the upper filter belt 21, and the other deviation correction limit unit 6 is located on the outside of the lower filter belt 22. When the detection rod of one deviation correction limit unit 6 contacts the upper filter belt 21, it indicates that the upper filter belt 21 is offset and needs to be corrected. When the detection rod of the other deviation correction limit unit 6 contacts the lower filter belt 22, it indicates that the lower filter belt 22 is offset and needs to be corrected. Specifically, when the upper filter belt 21 or the lower filter belt 22 contacts the detection rod in the corresponding deviation correction limit unit 6, the proximity switch on the detection rod will be sensed and control the corresponding deviation correction mechanism to achieve reliable deviation correction of the upper filter belt 21 or the lower filter belt 22. An over-limit unit 7 is also provided on the frame 1. When the upper filter belt 21 or the lower filter belt 22 contacts the detection rod of the over-limit unit 7, the proximity switch on the detection rod will be sensed and control the deviation correction mechanism to stop deviation correction or reverse deviation correction.

[0056] Figure 3 It is a schematic stereogram of the feeding mechanism. Figure 4 This is a cross-sectional view of the internal structure of the feeding mechanism. Figure 3 and Figure 4and in combination with Figure 1 At the top of the frame 1, a feeding mechanism 4 is provided. The feeding mechanism 4 includes a hopper 41 and a filtering unit 42. The hopper 41 is connected to the frame 1 through a bracket 13. One end of the hopper 41 is provided with an extension plate 418 which extends upward. At one end of the hopper 41 and on the extension plate 418, a feed pipe 411 is provided. At the other end of the hopper 41, a discharge pipe 412 is provided. The filtering unit 42 is arranged inside the hopper 41. The discharge end of the feed pipe 411 is located above the filtering unit 42, and the feed end of the discharge pipe 412 is located below the filtering unit 42. Moreover, the discharge end of the discharge pipe 412 is located above the feeding area 11. In this way, when the sludge is input into the hopper 41 from the feed pipe 411, it will first pass through the filtering unit 42. After the large particles are filtered out by the filtering unit 42, it is then conveyed to the feeding area 11 through the discharge pipe 412, which plays a role in filtering the sludge and prevents large particles from falling onto the lower filter belt 22 and damaging the lower filter belt 22 or the upper filter belt 21, effectively extending the service life of the upper filter belt 21 and the lower filter belt 22.

[0057] See Figure 4 As shown, the filtering unit 42 includes a first filtering frame 421, a second filtering frame 422 and a third filtering frame 424. Both the first filtering frame 421 and the second filtering frame 422 are in the shape of a Chinese character 'Ri', and the third filtering frame 424 is in the shape of a Chinese character 'Kou'. The first filtering frame 421 is close to the feed pipe 411 and its width is smaller than that of the second filtering frame 422. The third filtering frame 424 is arranged below the first filtering frame 421 and the second filtering frame 422. Moreover, filter plates 423 are provided in the first filtering frame 421, the second filtering frame 422 and the third filtering frame 424. The first filtering frame 421 and the second filtering frame 422 are arranged in the same plane and are in contact with each other. At the same time, the first filtering frame 421, the second filtering frame 422 and the third filtering frame 424 are all in contact with the inner wall of the hopper 41. In this way, the sludge must pass through the first filtering frame 421, the second filtering frame 422 and their corresponding filter plates 423, and then pass through the third filtering frame 424 and its corresponding filter plate 423 before it can enter the discharge pipe 412. The two-stage filtering operation ensures that the large particles in the sludge can be filtered out.

[0058] Figure 5 is a reference diagram of the position state of the first filtering frame and the second filtering frame, Figure 6 is Figure 5 the reference diagram of the action state of Figure 5 and Figure 6 and in combination with Figure 4, at the top of the hopper 41, there are a first mounting bracket 413 and a second mounting bracket 414. A hoist 415 is provided on each of the first mounting bracket 413 and the second mounting bracket 414. The suspension ropes of the two hoists 415 are respectively and correspondingly connected to the middle parts of the first filter frame 421 and the second filter frame 422. In this way, one hoist 415 is used to lift the first filter frame 421, and the other hoist 415 is used to lift the second filter frame 422. Since both the first filter frame 421 and the second filter frame 422 are in the shape of a Chinese character 'Ri', in the case of only one suspension rope, the stability during the lifting of the first filter frame 421 and the second filter frame 422 can be maximally improved, preventing the first filter frame 421 and the second filter frame 422 from deflecting simultaneously to cause filtering holes or getting stuck between the inner wall of the hopper 41.

[0059] See Figure 4, a baffle 4130 is provided on the inner wall of the first mounting frame 413, the baffle 4130 is located above the first filter frame 421 and close to the second filter frame 422, a pair of limit bars 4140 are provided on the inner wall of the second mounting frame 414, the limit bars 4140 and the second filter frame 422 interfere with each other in the vertical direction, the pair of limit bars 4140 are arranged obliquely and parallel to each other, and the height of one end of the limit bar 4140 close to the discharge pipe 412 is lower than the height of one end of the limit bar 4140 close to the feed pipe 411. When there are a lot of large particles trapped on the filter plates 423 of the first filter frame 421 and the filter plates 423 of the second filter frame 422, the two winches 415 are opened at the same time, so as to lift the first filter frame 421 and the second filter frame 422 at the same speed at the same time, ensuring that the filter plates 423 can still perform filtering operations during the lifting process. The bottom of the baffle 4130 is located on the inner side of the hopper 41, the top of the baffle 4130 is located on the outer side of the hopper 41, and the limit bar 4140 is located on the outer side of the hopper 41. In this way, after the first filter frame 421 and the second filter frame 422 rise a certain distance at the same time, the first filter frame 421 will contact the baffle 4130 and stop rising due to the obstruction of the baffle 4130. At this time, due to the small size of the first filter frame 421, the corresponding winch 415 can be stopped in time after contacting the baffle 4130 to prevent the first filter frame 421 from rotating. In other words, the first filter frame 421 remains in a horizontal state after stopping. After the first filter frame 421 stops under the limiting action of the baffle 4130, there is still a distance between the second filter frame 422 and the limiting bar 4140, and the second filter frame 422 can continue to rise. When the second filter frame 422 contacts the lowest point of the inclined limiting bar 4140, due to the large size of the second filter frame 422, the second filter frame 422 will rotate around the lowest point until the second filter frame 422 and the limiting bar 4140 are completely fitted. At this time, after stopping the corresponding winch 415, the second filter frame 422 can be in a tilted state. Since the limiting bar 4140 is completely located on the outside of the baffle 4130, and the bottom of the baffle 4130 is located on the inside of the hopper 41, when the second filter frame 422 is fitted with the limiting bar 4140, the first filter frame 421 is still located on the inside of the hopper 41, while the second filter frame 422 is located on the outside of the hopper 41, and the two are in a mutually misaligned state. Furthermore, the feed pipe 411 is located on the extension plate 418, which increases the setting height of the feed pipe 411, so that after both winches 415 stop, the first filter frame 421 can still be located below the discharge end of the feed pipe 411, and the second filter frame 422 can be located on the outside of the hopper 41. In this way, with the cooperation of the baffle 4130, the filter plate 423 in the first filter frame 421 can still filter the sludge transported by the feed pipe 411, while the filter plate 423 in the second filter frame 422 can be quickly and conveniently cleaned.During the simultaneous upward movement of the first filter frame 421 and the second filter frame 422, the landing point of the feed pipe 411 on the filter plate 423 of the first filter frame 421 changes, that is, the landing point moves in a direction away from the second filter frame 422, so that the sludge can wash the large particles on the filter plate 423 in the first filter frame 421 to the filter plate 423 in the second filter frame 422, thereby achieving a simple blowing of the filter plate 423 in the first filter frame 421, and ensuring that the two filter plates 423 can effectively filter the sludge.

[0060] See also Figure 3 and Figure 4 , an extension plate 418 is provided on one side of the top of the hopper 41, a guide plate 416 is provided on the other side of the top of the hopper 41, a guide groove 417 is provided on the outside of the hopper 41, the guide groove 417 is in an inverted V shape, the guide groove 417 is located below the guide plate 416, and both ends of the guide groove 417 are located outside the frame 1. When the second filter frame 422 is in contact with the limit bar 4140, the second filter frame 422 is in an inclined state and the height of the second filter frame 422 is higher than the height of the guide plate 416, so that the staff can quickly sweep and push the large particles on the filter plate 423 in the second filter frame 422 onto the guide plate 416, and the large particles fall into the guide groove 417 through the guide plate 416, and then slide toward the outside of the frame 1 from the guide groove 417. A recovery bin can be provided on the outside of the frame 1 to facilitate the collection of large particles and prevent large particles from falling around and affecting the operating environment.

[0061] See also Figure 1 and Figure 4, a tension sensor 43 is provided on the suspension ropes of the two winches 415, a controller is provided on the frame 1, and there is an electrical connection between the tension sensor 43 and the controller. The tension sensor 43 is used to collect the tension value of the suspension rope, and the controller is used to collect and analyze the tension value collected by the tension sensor 43 and control the feeding speed and the rotation speed of the winch 415. Specifically, when the first filter frame 421 and the second filter frame 422 are located at the inner lower part of the hopper 41 and filtering is performed, the first filter frame 421 and the second filter frame 422 are at the same height, and there is a distance between the first filter frame 421 and the third filter frame 424 in the vertical direction, so that one tension sensor 43 can collect the weight value of the first filter frame 421 and its filter plate 423, and the other tension sensor 43 can collect the weight value of the second filter frame 422 and its filter plate 423. When the filter plate 423 filters for a period of time and a large number of large particles are trapped on the filter plate 423, the value collected by the tension sensor 43 will increase. When the value increases and exceeds the preset value, the controller will start the hoist 415 (and the feeding speed can also be reduced at the same time), thereby lifting the first filter frame 421 and the second filter frame 422 and cleaning their filter plates 423. At this time, the filter plate 423 in the third filter frame 424 plays a role of standby filtering, that is, when the first filter frame 421 and the second filter frame 422 are rising, if an accidental rotation occurs, the filter plate 423 in the third filter frame 424 can still play a filtering role. Moreover, when the suspension rope breaks, the third filter frame 424 can limit the first filter frame 421 and the second filter frame 422, preventing the first filter frame 421 and the second filter frame 422 from falling completely to the bottom of the hopper 41 and failing to perform filtering operations.

[0062] Figure 7 This is a reference diagram of the position status of the fabric mechanism. Figure 8 This is a schematic three-dimensional diagram of the cloth mechanism. Figure 7 and Figure 8 Combined with Figure 1 The frame 1 is also provided with a material distributing mechanism 3. When the sludge is discharged through the discharge pipe 412 and just falls on the lower filter belt 22 and is not squeezed by the upper filter belt 21 and the lower filter belt 22, the material distributing mechanism 3 will evenly spread the sludge on the lower filter belt 22. The material distributing mechanism 3 is arranged in the feeding area 11. The material distributing mechanism 3 includes a fixed plate 31, a movable plate 32 and a connecting plate 33. The connecting plate 33 is used to connect the fixed plate 31 and the movable plate 32. The connecting plate 33 is flexible, and the movable plate 32 can rotate around the connecting plate 33.

[0063] Fig. 9 This is a reference diagram of the exploded state of the adjusting rod, sleeve and vertical plate. Fig. 9 Combined with Figure 1 and Figure 8A rotating seat 320 is provided on the top of the movable plate 32, and a vertical plate 310 is provided on the top of the fixed plate 31. The vertical plate 310 is connected to the frame 1 to fix the fixed plate 31. An adjusting rod 34 is passed between the vertical plate 310 and the rotating seat 320. A through hole 3100 is provided on the vertical plate 310. One end of the adjusting rod 34 is sleeved on the rotating seat 320 and can rotate around the rotating seat 320. The other end of the adjusting rod 34 passes through the vertical plate 310 through the through hole 3100. The other end of the adjusting rod 34 is threadedly connected with a nut 341, and the nut 341 contacts the side of the vertical plate 310 away from the rotating seat 320. The fixed plate 31 and the movable plate 32 are both arranged between the upper filter belt 21 and the lower filter belt 22 and are both inclined. The angle between the fixed plate 31 and the lower filter belt 22 is smaller than the angle between the movable plate 32 and the lower filter belt 22. In this way, under the action of gravity, the movable plate 32 can form a pulling effect on the adjustment rod 34, and the nut 341 can form a limiting effect on the adjustment rod 34. After rotating the nut 341 and adjusting the position of the nut 341 on the adjustment rod 34, the initial angle of the movable plate 32 can be reliably adjusted. According to different operating parameters, the initial angle of the movable plate 32 is reasonably adjusted so that a larger steady flow area can exist between the movable plate 32 and the lower filter belt 22, and the sludge is stabilized by the steady flow area to ensure that the sludge can smoothly enter between the fixed plate 31 and the lower filter belt 22 and be evenly spread on the lower filter belt 22 by the fixed plate 31.

[0064] See also Figure 7 and Fig. 9A sleeve 35 and an annular pressure sensor 36 are provided on the side of the vertical plate 310 facing away from the nut 341. The pressure sensor 36 is arranged on the inner side of the sleeve 35, and the sleeve 35, the pressure sensor 36 and the through hole 3100 are all arranged coaxially. A pressing plate 351 and a plurality of pressing rods 352 are arranged in the sleeve 35. The plurality of pressing rods 352 are arranged at intervals along the same circumference. One end of the pressing rod 352 is connected to the pressing plate 351, and the other end of the pressing rod 352 abuts against the pressure sensor 36. A limit plate 342 and a spring 343 are provided on the adjusting rod 34. One end of the spring 343 is connected to the limit plate 342, and the other end is connected to the pressing plate 351. The adjusting rod 34 is fixedly connected to the limit plate 342, and the adjusting rod 34 passes through the pressure plate 351 and the pressure sensor 36. There are gaps between the adjusting rod 34 and the pressure plate 351 and between the adjusting rod 34 and the pressure sensor 36. The limit plate 342 can move synchronously with the adjusting rod 34, while the pressure plate 351 will remain relatively stationary. At the same time, during the synchronous movement of the adjusting rod 34 and the limit plate 342, the limit plate 342 will form an extrusion effect on the spring 343, and the pressure exerted on the spring 343 will be transmitted to the pressure sensor 36 through the pressure plate 351 and the pressure rod 352, thereby causing the pressure value collected by the pressure sensor 36 to change. The pressure sensor 36 and the controller are electrically connected. The pressure sensor 36 is used to collect the pressure value exerted on the movable plate 32, and the controller is used to collect and analyze the pressure values ​​collected by the pressure sensor 36 and control the feeding speed and the rotation speed of the upper filter belt 21 and the lower filter belt 22.

[0065] During the operation of the dewatering machine, if the sludge maintains the same water content and the same feed speed, that is, the sludge can enter the distribution mechanism 3 in the same state, the angle of the movable plate 32 can be changed within a set smaller range, so that the movable plate 32 with a larger inclination angle can press the sludge flowing into the distribution mechanism 3, so that the sludge can enter between the fixed plate 31 and the lower filter belt 22 in a relatively stable state, thereby facilitating the fixed plate 31 to evenly spread the sludge. If the water content or feed speed of the sludge suddenly changes, the state of the sludge in the steady flow zone will change, and the pressure exerted by the sludge on the movable plate 32 will also change. Specifically, when the water content is low or the feed speed is high, the pressure on the movable plate 32 will increase, and the movable plate 32 will rotate toward the direction of the vertical plate 310, thereby expanding the space of the steady flow zone (too small or too large space in the steady flow zone will reduce the steady flow effect of the movable plate 32). In the process of sludge pushing the movable plate 32 to rotate, the pressure value collected by the pressure sensor 36 will also change greatly synchronously. When the pressure value exceeds the preset value, the controller will adjust the feed speed or the rotation speed of the upper filter belt 21 and the lower filter belt 22, so as to ensure that the sludge can quickly and evenly enter between the upper filter belt 21 and the lower filter belt 22, effectively preventing the sludge from accumulating before being squeezed and causing excessive tension of the upper filter belt 21 or the lower filter belt 22, thereby preventing the upper filter belt 21 or the lower filter belt 22 from tearing or breaking, and extending the service life of the upper filter belt 21 and the lower filter belt 22. The inner diameter of the perforation 3100 is larger than the outer diameter of the adjusting rod 34, and the outer diameter of the nut 341 is larger than the inner diameter of the perforation 3100. In this way, when the sludge pushes the movable plate 32 to rotate, the adjusting rod 34 can move radially and axially in the perforation 3100, which ensures that the adjusting rod 34 can be smoothly displaced. The nut 341 is larger in size and will not penetrate into the perforation 3100, which ensures that the nut 341 can limit the initial angle of the movable plate 32 to prevent the angle between the movable plate 32 and the lower filter belt 22 from being too small. The feeding operation of the sludge is completed by the sludge pump, and the rotation of the upper filter belt 21 and the lower filter belt 22 is completed by the motor. The controller adjusts the feeding speed by controlling the operating power of the sludge pump, and adjusts the rotation speed of the upper filter belt 21 and the lower filter belt 22 by controlling the operating power of the motor.

[0066] This embodiment also discloses a control method for an intelligent high-pressure belt-type deep dehydrator.

[0067] The control method of the intelligent high-pressure belt-type deep dehydrator comprises the following steps:

[0068] S1. Rotate the nut 341 to adjust the angle between the movable plate 32 and the lower filter belt 22 to 30°-35°. The controller controls the two winches 415 to synchronously lower the first filter frame 421 and the second filter frame 422 to the inner lower part of the hopper 41, and the distance between the first filter frame 421 and the third filter frame 424 is 5-10 cm.

[0069] S2, the controller controls the upper filter belt 21 and the lower filter belt 22 to rotate synchronously. At the same time, the feed pipe 411 transports the sludge into the hopper 41. The sludge passes through the filter plate 423 and is transported to the feed area 11 through the discharge pipe 412 and falls between the upper filter belt 21 and the lower filter belt 22. The dehydrated sludge is discharged from the discharge area 12. The process is completed.

[0070] In step S2, when the pressure value collected by the pressure sensor 36 is greater than the set value, the controller reduces the feed speed or increases the rotation speed of the upper filter belt 21 and the lower filter belt 22;

[0071] In step S2, when the tension value collected by the tension sensor 43 is greater than the set value, the controller reduces the feed speed or controls the winch 415 to start, and the winch 415 pulls the first filter frame 421 and the second filter plate 423 upward, thereby removing large particles trapped on the filter plate 423.

[0072] The present application monitors the overall weight of the first filter frame 421 and the second filter frame 422 through the tension sensor 43, and when the weight of any one of the first filter frame 421 and the second filter frame 422 exceeds a preset value, the controller can automatically adjust the feed speed and automatically control the winch 415 to synchronously lift the first filter frame 421 and the second filter frame 422, and restore the overall weight of the first filter frame 421 and the second filter frame 422 to the initial state through the cleaning action of the filter plate 423, ensuring that the filter plate 423 can reliably filter large particles, preventing large particles from damaging the upper filter belt 21 or the lower filter belt 22, and extending the service life of the upper filter belt 21 and the lower filter belt 22.

[0073] The present application also monitors the pressure from the sludge on the movable plate 32 through the pressure sensor 36, and when the pressure value exceeds the preset value, the controller can automatically adjust the feeding speed and the rotation speed of the upper filter belt 21 and the lower filter belt 22, thereby ensuring that the movable plate 32 and the fixed plate 31 can evenly spread the sludge on the lower filter belt 22 after cooperating with each other, preventing sludge from accumulating and damaging the upper filter belt and the lower filter belt 22, and further extending the service life of the upper filter belt 21 and the lower filter belt 22.

[0074] The electrical connection between the tension sensor 43 and the controller and the electrical connection between the pressure sensor 36 and the controller can transmit data accurately and in real time, ensuring that the controller can automatically adjust the feed speed, the rotation speed of the upper filter belt 21 and the lower filter belt 22 and the working state of the winch 415. The adjustment process is more intelligent, reducing the environment for manual participation in judgment and operation, improving the speed and accuracy of the operation, and thus making the control of the dehydration operation more precise and reliable.

[0075] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
