Description

Technical Field

[0001] This application relates to the field of solid-liquid separation technology for waste residue, specifically a leaching device for water-containing tank residue. Background Technology

[0002] In the surface treatment industry, during processes such as electroplating, pickling, and degreasing, insoluble fixed impurities gradually accumulate at the bottom of each treatment tank, forming tank slag. This slag needs to be cleaned regularly. The slag is removed from the treatment tank and placed into ton bags, which are then collected and placed in a designated area.

[0003] After the slag is loaded into ton bags, the moisture in the slag will seep out from the surface of the ton bags, which can easily contaminate the ground. Therefore, before placing the ton bags into the storage area, the operators use solid desiccant to absorb the liquid seeping out of the ton bags.

[0004] While the above treatment methods can absorb the liquid seeping from the desiccant bags, the desiccant itself is also hazardous waste after the liquid is absorbed, which increases the total amount of waste that needs to be treated. Summary of the Invention

[0005] The purpose of this application is to provide a leaching device for water-containing tank sludge, which aims to solve the technical problem that the method of absorbing leachate from ton bags by solid desiccant in the prior art leads to an increase in the total amount of waste to be treated.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A draining device for water-containing tank sludge is provided, comprising: The collection box has several support tubes connected at intervals inside to support the ton bags; each of the support tubes has several spaced detection ports at the top, and the support tube has a humidity detection structure corresponding to each detection port; the humidity detection structure includes a humidity sensor, a sealing component, and a driving component that drives the humidity sensor and the sealing component to slide along the axial direction of the support tube. A light curtain sensor is installed at the bottom of the support tube; the light curtain sensor includes a transmitting part connected to one side of the collection box and a receiving part connected to the other side of the collection box; A jacking structure is disposed inside the support tube; the jacking structure is used to jack the humidity sensor or to jack the sealing component. The control module is communicatively connected to the light curtain sensor, humidity sensor, pushing structure, and driving component; the sealing component blocks the detection port in the initial state. The control module is configured as follows: A light curtain sensor detects whether the ton bag is dripping downwards; when the light curtain sensor detects that the dripping has stopped, the push structure is controlled to reset downwards, and the sealing component separates from the detection port. The driving component is controlled to drive the humidity sensor and the sealing component to slide, so that the humidity sensor is aligned with the detection port; The pusher structure is controlled to push the humidity sensor so that the detection end comes into contact with the ton bag; It receives the detection signal from the humidity sensor, and determines that the draining is complete when the detected value is lower than the preset value.

[0007] In one possible implementation, the driver includes: A connecting plate is disposed inside the support tube and is arranged along the length of the support tube; the connecting plate has through holes that slide with the humidity sensor and the sealing component, and both the humidity sensor and the sealing component are connected to limiting components that contact the top of the connecting plate; A sliding cylinder is connected to the outside of the collection box; the connecting plate passes through the side wall of the collection box, and the side wall of the collection box has space for the connecting plate to slide; the piston rod of the sliding cylinder is connected to the protruding end of the connecting plate; The support tube has a limiting structure for radially limiting the connecting plate.

[0008] In one possible implementation, the limiting element on the humidity sensor has a guide hole, and the connecting plate has a guide rod that slides with the guide hole.

[0009] In one possible implementation, the connecting plate on each of the support tubes is connected via a drive plate, and the piston rod of the sliding cylinder is connected to the drive plate.

[0010] In one possible implementation, the limiting structure includes: Two sets of guide plates are respectively disposed on both sides of the connecting plate; each set of the connecting plates is connected to the inner peripheral wall of the support tube. Each set of guide plates consists of two plates, and a groove is formed between the two guide plates in each set for the sliding of the connecting plate.

[0011] In one possible implementation, one end of the slide has an opening, and the other end of the slide has a limiting surface; wherein, when the connecting plate contacts the limiting surface, the humidity sensor is aligned with the detection port.

[0012] In one possible implementation, the pushing structure includes: A push plate is disposed inside the support tube; both ends of the push plate pass through the two sides of the collection box, and the collection box has space for the push plate to slide. A push cylinder is connected to the outside of the collection box; the piston rod of the push cylinder is connected to the protruding end of the push plate. A guide structure is connected to the end of the support tube; the push plate has a through hole that slides with the guide structure. The push plate has a push position aligned with the detection port, and the push plate has through holes on both sides of the push position; when the humidity sensor is in the push position, the sealing member is located in one of the through holes; when the sealing member is in the push position, the humidity sensor is located in the other through hole.

[0014] In one possible implementation, the detection port of the support tube is provided with rounded corners, and the support tube has a downwardly angled guide channel on the inner wall of each detection port, which can guide the effluent entering the detection port.

[0015] In one possible implementation, a conical flow guide is connected inside the collection tank, the conical flow guide being located below the support tube; the lower end of the conical flow guide has a liquid outlet facing the bottom wall of the collection tank.

[0016] The above-mentioned configuration of this application allows the support tube inside the collection box to stably support the ton bag, allowing the water seeping out of the ton bag to drip naturally into the collection box for collection of the leachate; in the initial state, the sealing component blocks the detection port. At this time, the ton bag has just been placed into the collection box and is in the stage of concentrated leachate. By blocking the detection port with the sealing component, the amount of leachate entering the support tube from the detection port can be reduced.

[0017] The light curtain sensor can detect the dripping state of the ton bag. When the ton bag is not dripping, the push structure resets downwards, and the sealing part resets downwards under its own gravity. The drive component moves the humidity sensor to align with the detection port, and the push structure pushes the humidity sensor upwards so that the detection end of the humidity sensor contacts the ton bag to detect the humidity at the bottom of the ton bag.

[0018] When the humidity sensor detects a value lower than the preset value, the draining process is considered complete.

[0019] This application provides a draining device for water-containing tank slag. Compared with the prior art, the beneficial effect of this application is that it can achieve the draining of tank slag in ton bags without the use of solid desiccant, effectively reducing the total amount of waste to be treated.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figures 1-10 This application provides a dewatering device for sludge containing moisture in a tank, including a collection box 1, a light curtain sensor, a pushing structure 2, and a control module; the collection box 1 is internally connected with several support tubes 4 for supporting ton bags 3; each support tube 4 has several spaced detection ports 41 at its top, and the support tube 4 has a humidity detection structure 5 corresponding to each detection port 41; the humidity detection structure 5 includes a humidity sensor 51, a sealing component 52, and a driving component 53 for driving the humidity sensor 51 and the sealing component 52 to slide along the axial direction of the support tube 4; the light curtain sensor is located at the bottom of the support tube 4; the light curtain sensor includes a transmitting part 6 connected to one side of the collection box 1 and a receiving part 7 connected to the other side of the collection box 1.

[0024] The pushing structure 2 is installed inside the support tube 4; the pushing structure 2 is used to push the humidity sensor 51, or to push the sealing component 52; the control module is communicatively connected to the light curtain sensor, the humidity sensor 51, the pushing structure 2, and the drive component 53 respectively; the sealing component 52 blocks the detection port 41 in the initial state, and the control module is configured to: detect whether the ton bag 3 is dripping downwards through the light curtain sensor; when the light curtain sensor detects that the dripping has stopped, control the pushing structure 2 to reset downwards, and the sealing component 52 separates from the detection port 41; control the drive component 53 to drive the humidity sensor 51 and the sealing component 52 to slide so that the humidity sensor 51 is aligned with the detection port 41; control the pushing structure 2 to push the humidity sensor 51 so that the detection end contacts the ton bag 3; receive the detection signal from the humidity sensor 51, and determine that the draining is complete when the detection value is lower than the preset value.

[0025] This application provides a draining device for water-containing tank slag. Compared with the prior art, the beneficial effect of this application is that it can achieve the draining of tank slag in ton bags 3 without the use of solid desiccant, effectively reducing the total amount of waste to be treated.

[0026] With the above-mentioned settings of this application, during the dripping process of the ton bag 3, the detection port 41 is blocked by the sealing component 52, which can reduce the amount of dripping liquid entering the support tube 4; on the other hand, during the dripping stage, the humidity sensor 51 has not yet extended out of the detection port 41, and the humidity sensor 51 does not contact the bottom of the ton bag 3, thus avoiding meaningless detection by the humidity sensor 51 in a high humidity environment; it can also reduce the contact time between the humidity sensor 51 and the dripping liquid.

[0027] It should be noted that the inside of the collection box 1 has a stepped surface 11 for contacting the outer peripheral wall of the support pipe 4, which provides a certain degree of support. Both the support pipe 4 and the collection box 1 are made of corrosion-resistant material. Both ends of the support pipe 4 pass through the side of the collection box 1, and the support pipe 4 and the side of the collection box 1 are press-fitted to reduce leakage at the connection between the support pipe 4 and the collection box 1. The humidity sensor 51 is a corrosion-resistant humidity sensor. When the light curtain sensor is installed inside the collection box 1, the top of the light curtain sensor has a baffle 12 to reduce the amount of liquid that falls directly onto the light curtain sensor. The working principles of the humidity sensor 51 and the light curtain sensor are existing technologies and will not be described in detail here.

[0028] In some embodiments, such as Figures 1-10 As shown, the driving component 53 includes a connecting plate 531 and a sliding cylinder 532; the connecting plate 531 is disposed inside the support tube 4 and is arranged along the length direction of the support tube 4; the connecting plate 531 has through holes that slide and cooperate with the humidity sensor 51 and the sealing component 52 respectively, and the humidity sensor 51 and the sealing component 52 are each connected to a limiting component 533 that contacts the top of the connecting plate 531; the sliding cylinder 532 is connected to the outside of the collection box 1; the connecting plate 531 passes through the side wall of the collection box 1, and the side wall of the collection box 1 has space for the connecting plate 531 to slide; the piston rod of the sliding cylinder 532 is connected to the through end of the connecting plate 531; wherein, the support tube 4 has a limiting structure for radially limiting the connecting plate 531.

[0029] The diameter of the limiting member 533 is larger than the diameter of the through hole on the connecting plate 531. Therefore, when the limiting member 533 contacts the connecting plate 531, this is the lowest position of the humidity sensor 51 and the sealing member 52. The sealing member 52 includes a plug 521 and a connecting rod 522. The limiting member 533 is fixedly connected to the connecting rod 522, and the connecting rod 522 slides in conjunction with the through hole of the connecting plate 531.

[0030] The plug 521 fits snugly with the detection port 41, effectively sealing the opening and allowing it to slide in or out of the port. Since the liquid leaking from the ton bag 3 is not high-pressure liquid, and the outer wall of the support pipe 4 is curved, the liquid on the support pipe 4 can flow downwards along the surface, thus reducing the amount of liquid accumulating in the detection port 41 and decreasing the amount of liquid entering the support pipe 4 from between the detection port 41 and the plug 52.

[0031] For example, the limiting structure inside the support tube 4 can radially limit the connecting plate 531, ensuring the stability of the connecting plate 531 during sliding and reducing radial displacement of the connecting plate 531. Specifically, the limiting structure includes two sets of guide plates 42, which are respectively disposed on both sides of the connecting plate 531; each set of connecting plates 531 is connected to the inner peripheral wall of the support tube 4; wherein, each set of guide plates 42 consists of two plates, and a groove 43 for sliding of the connecting plate 531 is formed between the two guide plates 42 in each set.

[0032] The guide plate 42 is fixed on the inner circumferential wall of the support tube 4. Taking one set of guide plates 42 as an example, one side of the connecting plate 531 is slidably engaged with the slide groove 43. The top and bottom of the connecting plate 531 are in contact with the corresponding guide plate 42 respectively. The connecting plate 531 and the guide plate 42 are in clearance engagement so that the connecting plate 531 can slide in the slide groove 43.

[0033] The side wall of the connecting plate 531 contacts the inner peripheral wall of the support tube 4, which can reduce the occurrence of the connecting plate 531 shifting along the width direction of the slide groove 43, thereby ensuring that the humidity sensor 51 and the sealing component 52 can be aligned with the detection port 41 respectively.

[0034] In some embodiments, such as Figures 1-10 As shown, the limiting member 533 on the humidity sensor 51 has a guide hole, and the connecting plate 531 has a guide rod 534 that slides with the guide hole.

[0035] The guide rod 534 is fixed on the connecting plate 531. Through the sliding cooperation between the guide rod 534 and the limiting member 533 on the humidity sensor 51, the up and down movement of the humidity sensor 51 can be guided, reducing the possibility of the humidity sensor 51 shifting during the sliding process.

[0036] In some embodiments, such as Figures 1-10 As shown, the connecting plate 531 on each support tube 4 is connected by the drive plate 54, and the piston rod of the sliding cylinder 532 is connected to the drive plate 54. The connecting plate 531 and the drive plate 54 can be fixed together by bolts and nuts. That is, corresponding through holes are provided on the connecting plate 531 and the drive plate 54. The threaded end of the bolt passes through the through holes on the connecting plate 531 and the drive plate 54 respectively, and then the protruding end of the bolt is threaded with the nut, which can fix the connecting plate 531 and the drive plate 54 together.

[0037] After connecting several connecting plates 531 together via the drive plate 54, the extension and retraction of the piston rod of the sliding cylinder 532 can simultaneously drive several connecting plates 531 to slide within their respective support tubes 4, ensuring that the switching actions of all detection points are consistent and reducing the number of drive components used.

[0038] For example, the sliding cylinder 532 is fixed to the outside of the collection box 1 by the mounting bracket 55, the drive plate 54 has a limiting plate 541, and the mounting bracket 55 has a limiting groove 551 for sliding the limiting plate 541; when the limiting plate 541 contacts one end of the limiting groove 551, the humidity sensor 51 is aligned with the detection port 41; when the limiting plate 541 contacts the other end of the limiting groove 551, the sealing member 52 is aligned with the detection port 41.

[0039] In some embodiments, such as Figures 1-10 As shown, one end of the slide 43 has an opening, and the other end of the slide 43 has a limiting surface; wherein, when the connecting plate 531 contacts the limiting surface, the humidity sensor 51 is aligned with the detection port 41.

[0040] With the above settings, the initial installation position can be determined by the contact between the connecting plate 531 and the limiting surface of the slide 43, thus reducing the installation error of the connecting plate 531. By providing an opening at one end of the slide 43, the connecting plate 531 can extend out of the support tube 4, thereby allowing the connecting plate 531 to be fixed to the drive plate 54 by bolts and nuts.

[0041] In some embodiments, such as Figures 1-10 As shown, the push structure 2 includes a push plate 21, a push cylinder 22, and a guide structure 23; the push plate 21 is disposed inside the support tube 4; both ends of the push plate 21 pass through the two sides of the collection box 1, and the collection box 1 has space for the push plate 21 to slide; the push cylinder 22 is connected to the outside of the collection box 1; the piston rod of the push cylinder 22 is connected to the protruding end of the push plate 21; the guide structure 23 is connected to the end of the support tube 4; the push plate 21 has a through hole that slides with the guide structure 23.

[0042] The push plate 21 has a push position aligned with the detection port 41, and the push plate 21 has through holes on both sides of the push position; when the humidity sensor 51 is in the push position, the sealing member 52 is in one of the through holes; when the sealing member 52 is in the push position, the humidity sensor 51 is in the other through hole.

[0043] The push plate 21 is located below the connecting plate 531. The push plate 21 on each support tube 4 is connected to the same horizontal plate 24. The push plate 21 and the horizontal plate 24 can be fixed by bolts and nuts. The fixing method is the same as that of the connecting plate 531 and the drive plate 54, and will not be described again here.

[0044] The push cylinder 22 is fixed to the outside of the collection box 1, and the piston rod of the push cylinder 22 is connected to the horizontal plate 24. By extending and retracting the piston rod of the push cylinder 22, the horizontal plate 24 can be driven to rise and fall, thereby driving several push plates 21 to rise and fall, pushing the humidity sensor 51 of each detection point to the detection port 41, or pushing the sealing part 52 of each detection point to the detection port 41.

[0045] For example, by providing guide structures 23 at both ends of the support tube 4 and providing through holes on the push plate 21 that slide in conjunction with the guide structures 23, the push plate 21 can be guided during lifting and lowering, improving the stability of the lifting and lowering process. Specifically, the guide structure 23 includes a guide post, which is fixed at the end of the support tube 4. The top of the guide post is lower than the bottom of the connecting plate 531.

[0046] During installation, first align the through hole of the push plate 21 with the guide post, then install the push plate 21 downwards; fix several push plates 21 to the horizontal plate 24 with bolts and nuts, adjust the height of the horizontal plate 24, and finally connect the piston rod of the push cylinder 22 to the horizontal plate 24. By setting the top of the guide post lower than the bottom of the connecting plate 531, the guide post will not interfere with the connecting plate 531 when it is installed on the support tube 4.

[0047] For example, a push rod 25 can be fixedly installed at the bottom of the push plate 21. The push rod 25 contacts the bottom inside the support tube 4 to limit the initial position of the push plate 21, so that the height of the push plate 21 does not need to be adjusted later.

[0048] In some embodiments, such as Figures 1-10 As shown, the bottom of the humidity sensor 51, the bottom of the sealing member 52, and the top of the push plate 21 are on the same plane, and the top of the humidity sensor 51 and the top of the sealing member 52 are on the same plane; wherein, the pushing distance of the push plate 21 is the same as the distance between the top of the humidity sensor 51 and the detection port 41.

[0049] With the above settings, the humidity sensor 51 and the sealing component 52 can be kept at the same height. After the humidity sensor 51 and the sealing component 52 move laterally, the bottom of the humidity sensor 51 will not be lower than the top of the push plate 21, or the bottom of the sealing component 52 will not be lower than the top of the push plate 21. Therefore, after switching, the push plate 21 can push the humidity sensor 51 or the sealing component 52.

[0050] It should be noted that in the initial position, the limiting member 533 on the humidity sensor 51 is in contact with the top of the connecting plate 531, and the limiting member 533 on the sealing member 52 is also in contact with the top of the connecting plate 531. At this time, the humidity sensor 51 and the sealing member 52 are at the same height and can slide in the support tube 4 under the drive of the connecting plate 531.

[0051] When the humidity sensor 51 is in the push position and the sealing part 52 is in the through hole position, the push plate 21 pushes the humidity sensor 51 under the drive of the push cylinder 22; when the push plate 21 contacts the connecting plate 531, the push plate 21 is pushed into place so that the detection end of the humidity sensor 51 contacts the bottom of the ton bag 3.

[0052] During the top pushing process, since the sealing member 52 is aligned with the through hole on the push plate 21, the push plate 21 will not push the sealing member 52, and the sealing member 52 will not interfere with the rising process of the push plate 21.

[0053] For example, the process is the same when the push plate 21 pushes the sealing member 52, except that the humidity sensor 51 is aligned with the through hole on the push plate 21. The humidity sensor 51 will not interfere with the rising process of the push plate 21, and the humidity sensor 51 will not be lifted.

[0054] In some embodiments, such as Figures 1-10 As shown, the detection port 41 of the support tube 4 is provided with rounded corners, and the inner wall of each detection port 41 of the support tube 4 has a downwardly inclined guide channel 44, which can guide the effluent entering the detection port 41.

[0055] By setting a rounded corner at the detection port 41, the ton bag 3 can make smooth contact with the detection port 41 on the support tube 4, reducing the possibility of scratching the ton bag 3. When the sealing member 52 seals the detection port 41, the top of the sealing member 52 is higher than the connection between the guide channel 44 and the detection port 41. When the effluent enters the detection port 41 from the rounded corner, the effluent can be discharged from the guide channel 44, reducing the effluent accumulation in the detection port 41.

[0056] In some embodiments, such as Figures 1-10 As shown, a conical guide shroud 8 is connected inside the collection tank 1, and the conical guide shroud 8 is located below the support tube 4; the lower end of the conical guide shroud 8 has a liquid outlet 81 facing the bottom wall of the collection tank 1.

[0057] With the above setup, a conical guide hood 8 is connected inside the collection box 1. After the dripping liquid falls into the conical guide hood 8, it is collected by the conical guide hood 8 and discharged into the outlet 81 at the lower end.

[0058] Because the conical guide shroud 8 blocks the internal space of the collection box 1, the effluent mainly accumulates in the area between the conical guide shroud 8 and the bottom wall of the collection box 1; without affecting the collection of effluent, it can reduce the area of ​​the effluent surface exposed to the air in the collection box 1, thereby slowing down the natural evaporation of effluent.

[0059] It should be noted that the same collection tank 1 can only handle leachate from one type of treatment tank, and leachate from different treatment tanks cannot be placed in the same collection tank 1 for drainage.

[0060] For example, the collection box 1 has a drain pipe on its side near the bottom wall, and a sampling pipe is provided on the drain pipe; both the drain pipe and the sampling pipe are provided with valves, and the sampling pipe is located between the valve of the drain pipe and the collection box 1. Therefore, without opening the valve of the drain pipe, the filtrate in the collection box 1 can be allowed to flow out from the sampling pipe by opening the valve on the sampling pipe, which is convenient for sampling.

[0061] The workflow of this embodiment is as follows: In the initial state, the sealing component 52 blocks the detection port 41 under the pushing of the pushing structure 2, reducing the amount of liquid entering the support pipe 4 from the detection port 41 during the dripping stage of the ton bag 3.

[0062] The ton bag 3 containing the slag is hoisted onto the support pipe 4 of the collection box 1. Water inside the ton bag 3 will seep out from the surface of the ton bag 3 and drip down into the collection box 1. During the dripping process of the ton bag 3, the transmitting part 6 of the light curtain sensor continuously transmits the light curtain signal to the receiving part 7. When a drop of liquid falls, it will block the light curtain. The control module determines whether the ton bag 3 is still dripping based on the blocking status of the light curtain.

[0063] When the light curtain sensor does not detect a dripping signal for 30 consecutive minutes, it is determined that there is no obvious dripping in the ton bag 3. At this time, a second detection can be performed, that is, the humidity at the bottom of the ton bag 3 is detected by the humidity sensor 51.

[0064] The control module controls the pushing structure 2 to reset downwards, and the sealing component 52 can reset downwards under its own gravity, separating the sealing component 52 from the detection port 41. By driving the connecting plate 531 to slide along the axis of the support tube 4 through the driving component 53, the humidity sensor 51 can be aligned with the detection port 41. At this time, the control module controls the pushing structure 2 to push the humidity sensor 51 upwards, so that the humidity sensor 51 contacts the bottom of the ton bag 3, and detects the humidity at the bottom of the ton bag 3.

[0065] When all humidity sensor 51 readings are lower than the preset value, the control module determines that the draining is complete.

[0066] For example, an audible and visual alarm can be installed on the collection box 1. The audible and visual alarm is connected to the control module. After the drainage is completed, the control module controls the audible and visual alarm to sound an alarm, so as to prompt the operator to transfer the ton bag 3 to the storage area.
