Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a self-weighing sludge dewatering and self-drying device. Background Technology

[0002] Solid materials separated or intercepted during the treatment of domestic sewage and industrial wastewater are collectively referred to as sludge. As an important part of the treatment of domestic sewage and industrial wastewater, sludge dewatering treatment can reduce the water content, changing it from a fluid to a solid state to achieve the purpose of volume reduction; on the other hand, it can stabilize organic matter, making it less prone to decomposition, avoiding secondary pollution to the environment, and facilitating the transportation and final disposal of sludge.

[0003] Existing sludge dewatering devices generally employ mechanical dewatering methods to achieve solid-liquid separation of sludge. While this saves manpower, it still suffers from low efficiency due to relying solely on mechanical methods. Furthermore, existing sludge dewatering devices cannot directly weigh the sludge before and after dewatering; separate weighing equipment is required before and after dewatering, which also results in cumbersome operation and low automation. Summary of the Invention

[0004] The purpose of this invention is to provide a self-weighing sludge dewatering and self-drying device. The side buckle assembly allows for the safe assembly and disassembly of the top box component and the base component. The rotatable heating component, in conjunction with the screw-on filter bag component, enables efficient dewatering. The side spring tooth component forms a transmission connection between the side buckle assembly and the screw-on filter bag component, thereby improving safety in multiple ways.

[0005] The objective of this invention is achieved through the following technical solution: a self-weighing sludge dewatering and self-drying device, comprising a base component, a top box component, a screw-on filter bag assembly, a side buckle assembly, a side spring tooth assembly, and a liftable weighing component. The base component includes a bottom shell, the top box component includes a top box body, the screw-on filter bag assembly includes a screw-on bevel gear, the side buckle assembly includes a side buckle, an inner locking platform, and an inner pushing platform, the side spring tooth assembly includes side locking teeth, and the liftable weighing component includes a weighing sliding sleeve.

[0006] The bottom of the top box can rest against the top of the bottom shell, and a sludge collection hopper is connected to the bottom of the top box;

[0007] Rotatable heating components are symmetrically installed at the inner bottom of the sludge collection hopper;

[0008] Both sides of the inner top of the top box are screwed with a screwing frame, and a detachable filter bag is connected between the screwing frames. The screwing bevel gear is fixed to the outer end of the middle of the screwing frame, which can drive the two sets of screwing frames to rotate in the same or opposite directions.

[0009] Side swing arms are screwed to the middle of the top two outer sides of the bottom shell, and side clips are fixed to the middle of the bottom two outer sides of the top shell. One end of the side clip is screwed to the middle of the side swing arm, and the other end is provided with an inner clip platform and an inner push platform. The top two outer sides of the bottom shell are also symmetrically vertically slidable with the side clips as the center. Each set of limited slides is fixedly connected to an upward inclined column on the outside, and the two outer sides of the side clips are slidably connected to the symmetrically distributed inclined columns.

[0010] Each set of side plates is connected to an elastically upward-facing top connecting plate. The side locking teeth are fixed to the inner side of the top of the top connecting plate. When the top connecting plate is elastically supported, the side locking teeth are in the position of engaging with the teeth of the rotating bevel gear. When the side swing arm rotates downward, it drives the side buckle to make the inner locking platform and the side plate fit together and press against each other. Then, the inner pushing platform can press the outer end of the top connecting plate to disengage the side locking teeth from the teeth of the rotating bevel gear.

[0011] The top box body has symmetrically fixed support side plates on both sides of its outer main surface, and the liftable weighing sliding sleeve is connected to the main body of the bottom shell.

[0012] The process of using the technical solution of the present invention is as follows:

[0013] Add the mud-water mixture to be dewatered into the filter bag. The main body of the filter bag is made of woven material with a certain mesh count. Under its own gravity, some of the sewage in the mud-water mixture will fall through the pores of the filter bag into the sludge collection hopper.

[0014] Before dehydrating and drying the mud-water mixture in the filter bag, the rotatable side swing arm can drive the side buckle to rotate in the direction of the inclined column, so that the inner buckle can press against the outer top of the side buckle plate, and the top box and the bottom shell can form a stable connection.

[0015] Furthermore, during the process of the inner clamping platform pressing against the outer top of the side clamping plate, the inner pushing platform will abut against the outer top surface of the top connecting plate. As the inner clamping platform is fully pressed against the outer top of the side clamping plate, the downward-moving top connecting plate can drive the side clamping teeth to disengage from the rotating bevel gear, allowing the rotating bevel gear to rotate freely.

[0016] When the inner card plate does not form a close and pressing fit with the side card plate, the weighing work can be carried out before dehydration and drying. The top of the automatically lifting weighing slide sleeve abuts against the supporting side plate, so that the top box and the mud-water mixture inside the top box are supported and lifted by the weighing slide sleeve to weigh the mud-water mixture before dehydration and drying.

[0017] After weighing the mud-water mixture before dehydration and drying, the rotatable heating component at the bottom of the sludge collection hopper can be activated, and the valve in the middle of the bottom of the sludge collection hopper can be opened to allow the sewage to be discharged from the sludge collection hopper. At the same time, the rotary drive mechanism connected to the rotary bevel gear is activated, so that the two sets of rotary bevel gears rotate in opposite directions to rotary press and compress the mud-water mixture in the filter bag, accelerate the outflow of sewage from the filter bag pores, and dry the mud-water mixture in the filter bag through the rotatable heating component, so that it gradually forms mud material.

[0018] After dewatering and drying, the rotatable heating component is turned off, and the inner clamping platform is disassembled from the side clamping plate by rotating the side swing arm. The weighing slide sleeve is used again to weigh the top box and the sludge inside the top box to obtain the difference in sludge before and after dewatering.

[0019] The filter bag is unfolded and flipped downwards by switching between two sets of rotating bevel gears in opposite directions and in the same direction, so that the mud falls to the top surface of the sludge collection hopper and is discharged from the outlet in the middle of the bottom of the sludge collection hopper.

[0020] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0021] (1) The present invention first sets the top box and the bottom shell as a detachable split structure. One purpose is to facilitate the maintenance of the components in the top box and the inner cavity of the sludge collection hopper, as well as the cleaning of the sludge attached therein.

[0022] (2) The filter bag of the present invention is detachably connected between two sets of screwing frames, which makes it convenient to replace the filter bag. By keeping the two sets of screwing frames rotating in opposite or the same direction, the filter bag can be used as a container to screw and press the mud-water mixture in the filter bag to improve the dewatering effect. At the same time, after the dewatering and drying is completed, the filter bag opening can be opened downwards, so that the dewatered and dried mud can be discharged downwards through the sludge collection hopper.

[0023] (3) In order to improve the safety of the connection between the top box and the bottom shell, the present invention also connects a side buckle assembly between the middle of the bottom end on both sides of the top box and the middle of the top end on both sides of the bottom shell. The side buckle is driven by the rotatable side swing arm to rotate in the direction of the inclined column, so that the inner buckle can be engaged and disengaged from the side buckle plate. Only after the inner buckle is engaged with the top of the side buckle plate can the side buckle teeth that are elastically slid in the side buckle plate completely disengage from the screwing bevel gear, so that the screwing frame can rotate freely, thereby doubly improving the safety of the operation process.

[0024] (4) Another purpose of this invention is to set the top box and the bottom shell as a detachable split structure, and to connect the side buckle assembly between the middle of the bottom end on both sides of the top box and the middle of the top end on both sides of the bottom shell. This allows the supporting side plates on both sides of the outer main surface of the top box to be contacted and abutted in conjunction with the movable weighing sliding sleeve. This makes it convenient to weigh the sludge before and after dewatering and drying, and quickly obtain the difference between the weight of the mud-water mixture before dewatering and drying and the weight of the sludge after dewatering and drying.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] like Figures 1-14 As shown, a self-weighing sludge dewatering and self-drying device is provided. The bottom end of the top box 202 can rest against the top opening of the bottom shell 101. The inner bottom of the top box 202 is connected to a sludge collection hopper 203, which can collect and guide sewage and sludge.

[0044] A rotatable heating element 8 is symmetrically installed at the inner bottom of the sludge collection hopper 203;

[0045] Both sides of the inner top of the top box 202 are screwed with a screwing frame 303. A detachable filter bag 305 is connected between the screwing frames 303. A screwing bevel gear 306 is fixed to the middle outer end of the screwing frame 303, which can drive the two sets of screwing frames 303 to rotate in the same or opposite directions.

[0046] Side swing arms 403 are screwed onto the middle of the top two outer sides of the bottom housing 101. Side locking plates 401 are fixed to the middle of the bottom two outer sides of the top housing 202. One end of the side buckle 407 is screwed onto the middle of the side swing arm 403, and the other end is provided with an inner locking platform 408 and an inner pushing platform 409. The top two outer sides of the bottom housing 101 are also symmetrically vertically slidably connected to the limiting slides 411 with the side buckle 407 as the center. Each set of limiting slides 411 is fixedly connected to an inclined column 412 with an upward tilt. The two outer sides of the side buckle 407 are slidably connected to the symmetrically distributed inclined columns 412. By rotating the side swing arm 403, the side buckle 407 can be driven to rotate in the tilt direction of the inclined column 412 as a guide, so as to realize the locking and disengaging action of the inner locking platform 408 onto the side locking plate 401.

[0047] Each set of side plates 401 has an elastically upward-facing top connecting plate 503 connected to its main body. The side locking teeth 506 are fixed to the inner side of the top of the top connecting plate 503. When the top connecting plate 503 is elastically supported, the side locking teeth 506 are in the position of engaging with the teeth of the rotating bevel gear 306. After the side swing arm 403 rotates downward and drives the side buckle 407 to make the inner locking platform 408 and the side plate 401 fit together and press against each other, the inner pushing platform 409 can press the outer end of the top connecting plate 503 to disengage the side locking teeth 506 from the teeth of the rotating bevel gear 306.

[0048] The top box 202 is also symmetrically fixed with support side plates 606 on both sides of its outer main surface. The liftable weighing slide 601 is connected to the main body of the bottom shell 101, so that the top of the weighing slide 601 abuts against the support side plate 606, thereby realizing the weighing operation of the top box 202 and the objects connected to the top box 202.

[0049] The working principle is as follows:

[0050] The top housing 202 and the bottom housing 101 are detachable, and the filter bag 305, which is fixed between the two sets of screwing frames 303, can also be removed and replaced.

[0051] A mud-water mixture to be dewatered can be added into the filter bag 305. The main body of the filter bag 305 is a woven material with a certain mesh count. Under its own gravity, some of the sewage in the mud-water mixture will fall through the pores of the filter bag 305 into the sludge collection hopper 203.

[0052] Before dehydrating and drying the mud-water mixture in the filter bag 305, in order to ensure the safety of the operation, it is necessary to make a stable connection between the top box 202 and the bottom shell 101.

[0053] The rotatable side swing arm 403 can drive the side buckle 407 to rotate in the direction of the tilt of the inclined column 412, so that the inner card table 408 can press against the outer top of the side card plate 401.

[0054] Furthermore, during the process of the inner clamping platform 408 pressing against the outer top of the side clamping plate 401, the inner pushing platform 409 will abut against the outer top surface of the top connecting plate 503. After the inner clamping platform 408 is completely pressed against the outer top of the side clamping plate 401, the downward moving top connecting plate 503 can drive the side clamping tooth 506 to disengage from the rotating bevel gear 306, allowing the rotating bevel gear 306 to rotate freely.

[0055] In other words, when the inner locking platform 408 does not form a close and pressing fit with the side locking plate 401, the side locking tooth 506 will be engaged with the rotating bevel gear 306 under the action of the elastic force of the top connecting plate 503, so that the rotating bevel gear 306 cannot rotate freely. Only after the top box 202 and the bottom box 101 form a stable connection through the cooperation of the inner locking platform 408 and the side locking plate 401 can the rotating bevel gear 306 enter the free rotation state.

[0056] When the inner card plate 408 does not form a close and pressing fit with the side card plate 401, the weighing work before dehydration and drying can be carried out. The top of the automatically lifting weighing slide sleeve 601 abuts against the supporting side plate 606, so that the top box 202 and the mud-water mixture inside the top box 202 are supported and lifted by the weighing slide sleeve 601, and the mud-water mixture is weighed before dehydration and drying.

[0057] After weighing the mud-water mixture before dehydration and drying, the rotatable heating component 8 at the bottom of the collection hopper 203 can be activated, and the valve at the bottom center of the collection hopper 203 can be opened to allow sewage to be discharged from the collection hopper 203. At the same time, the rotary drive mechanism connected to the rotary bevel gear 306 is activated, so that the two sets of rotary bevel gears 306 rotate in opposite directions to rotary press and compress the mud-water mixture located in the filter bag 305, accelerate the outflow of sewage from the pores of the filter bag 305, and dry the mud-water mixture located in the filter bag 305 through the rotatable heating component 8, so that it gradually forms mud.

[0058] After dehydration and drying are completed, the rotatable heating component 8 is turned off, and the inner card plate 408 is disassembled from the side card plate 401 by rotating the side swing arm 403. The weighing slide sleeve 601 is used again to weigh the top box 202 and the sludge inside the top box 202 to obtain the difference in sludge before and after dehydration.

[0059] The filter bag 305 is unfolded and flipped downward by switching between the relative opposite and same direction rotation of two sets of rotating bevel gears 306, so that the mud falls to the top surface of the sludge collection hopper 203 and is discharged from the outlet at the bottom center of the sludge collection hopper 203.

[0060] This allows for the automatic dewatering of sludge and the weighing of sludge before and after dewatering.

[0061] The specific structures of the base component 1 and the top box component 2 are as follows: Figure 2 and Figure 3 As shown, bottom side seats 102 are symmetrically fixed at the bottom ends of both sides of the outer main surface of the bottom shell 101. The top end of the bottom connecting frame 103 is fixedly connected to the bottom end of the bottom side seat 102, which can play the role of supporting the bottom shell 101.

[0062] Furthermore, depending on the actual working conditions, the bottom connecting frame 103 can be replaced with a concrete wall to improve the support strength and support height of the bottom shell 101, making it easier for the unloading and transfer vehicle to move directly under the bottom shell 101.

[0063] The 201 is placed symmetrically on the outer side of the top of the bottom housing 101, which can improve the stability of the connection between the bottom of the top housing 202 and the top of the bottom housing 101.

[0064] A sewage pipe 204 is connected to the middle of the bottom of the sewage collection hopper 203, and a sewage valve 205 is installed in the bottom pipe of the sewage pipe 204.

[0065] The specific structure of the screw-on filter bag assembly 3 is as follows: Figure 4 and Figure 5As shown, the screw shaft seats 301 are symmetrically installed at the top center of the top box 202. Each set of screw frames 303 has a screw shaft 302 fixed at the outer center. The screw shaft 302 is rotatably connected in the screw shaft seat 301. The screw bevel gear 306 is inserted and fixed at the outer end of the screw shaft 302.

[0066] Each set of rotating bevel gears 306 has a side bevel gear 307 meshing on one side. The two outer sides of the top housing 202 are symmetrically fixed with side shaft seats 308. The side shaft 309 is rotatably connected in the side shaft seat 308. The side bevel gear 307 is inserted and fixed at one end of the side shaft 309. The other end of the side shaft 309 is inserted and fixed with an external connecting pulley 310. The drive pulley 312 is fixedly installed on the outer main surface of the top housing 202. A rotary motor 311 is inserted and fixed in the rotating shaft of each set of drive pulleys 312. A connecting belt 313 is sleeved between the rotary motor 311 on the same side and the external connecting pulley 310.

[0067] Furthermore, the drive pulley 312 can drive the rotary motor 311 to rotate in both directions, thereby driving the turning bevel gear 306 to rotate in both directions through the transmission mechanism, which in turn can drive the two sets of turning frames 303 to maintain a rotating state in opposite or the same direction.

[0068] Furthermore, the screwing frame 303 has a V-shaped structure, and connecting studs 304 are fixed at the inner end points and corners of the screwing frame 303. The two sides of the filter bag 305 are connected and installed with stud insertion holes 314 at the positions directly opposite to each set of connecting studs 304. The stud insertion holes 314 can be inserted into the connecting studs 304 and fastened with standard nuts.

[0069] Furthermore, since the filter bag 305 itself has a certain depth, the sludge that needs to be dehydrated and dried is kept within the safety limit of the filter bag 305, so that when the filter bag 305 is twisted, the sludge will not leak from the filter bag 305, or only a small amount of sludge is allowed to leak.

[0070] The specific structure of the side buckle assembly 4 is as follows: Figure 6 and Figure 7 As shown, each set of card holders 201 has a swing arm seat 402 fixed to the inner end of its outer side. The inner end of the side swing arm 403 is rotatably connected to the swing arm seat 402 on the same side. The bottom end of the outer side of the bottom housing 101 is fixed to the middle of the bottom end of the side hydraulic cylinder base 404. The bottom end of the main body of the side hydraulic cylinder 405 is rotatably connected to the side hydraulic cylinder base 404. The telescopic rod of the side hydraulic cylinder 405 is rotatably connected to the outer end of the side swing arm 403.

[0071] The main body of the side swing arm 403 is symmetrically and laterally fixed with a buckle seat 406 at the middle of the outer end. The bottom ends of the side buckles 407 are respectively rotatably connected to different buckle seats 406.

[0072] The inner end of the outer side of the card holder 201 is also vertically fixed with a limiting slide rail 410, and the limiting slide block 411 on the same side is slidably connected in the limiting slide rail 410.

[0073] The two outer ends of the side buckle 407 are symmetrically fixed with inclined slides 413, and the inclined posts 412 on the same side are slidably connected in the inclined slides 413. Each set of inclined posts 412 is connected to a fixed sleeve at its outer end to prevent the inclined slides 413 from slipping out of the inclined posts 412.

[0074] By synchronously activating two symmetrically distributed sets of side hydraulic cylinders 405, the side swing arm 403 can be driven to rotate within a certain range with the swing arm rotating seat 402 as the reference. This can drive the side buckle 407 to rotate with the sliding guide formed by the inclined column 412 and the inclined slide seat 413. As a result, when the side swing arm 403 is rotating, the side buckle 407 can dynamically maintain a fixed angle with the limiting slide rail 410, which facilitates the inner clamping platform 408 and the side clamping plate 401 to press against each other and disengage.

[0075] The specific structure of the side spring tooth assembly 5 is as follows: Figure 8 and Figure 9 As shown, each set of side plates 401 has symmetrically provided spring pin sliding holes 501 in its main body. The elastic sliding pin 502 is slidably connected in the spring pin sliding hole 501. The top connecting plate 503 is fixedly connected to the top of the elastic sliding pin 502 on the same side. The bottom end of each set of elastic sliding pins 502 is fitted with a bottom sleeve 504.

[0076] Each set of elastic sliding pins 502 is also fitted with a top spring 505. One side of the top spring 505 is fixed to the bottom end of the top connecting plate 503, and the other side is fixed to the top end of the side plate 401.

[0077] With the support and elastic force of the top spring 505 on the top connecting plate 503 and the limitation of the top connecting plate 503's upward position by the bottom sleeve 504, the side locking tooth 506 can be in the position of engaging with the teeth of the upward rotating bevel gear 306 when the top connecting plate 503 is not pushed downward by external force.

[0078] The specific structure of the liftable weighing component 6 is as follows: Figure 10 and Figure 11 As shown, the main body of the weighing sliding sleeve 601 is sleeved on the outside of the bottom shell 101. The outer main surface of the weighing sliding sleeve 601 is symmetrically fixed with an outer guide seat 602. The outer guide post 603 is fixedly connected to the outer main surface of the bottom shell 101 through the guide post fixed seats 604 at the upper and lower ends. The outer guide seat 602 on the same side is slidably connected in the outer guide post 603.

[0079] Each set of bottom side seats 102 is equipped with a lifting hydraulic cylinder 605 at the top, and the top of the telescopic rod of the lifting hydraulic cylinder 605 is fixedly connected to the bottom of the weighing slide sleeve 601. Through the joint action of the set of lifting hydraulic cylinders 605, the weighing slide sleeve 601 can be raised and lowered stably.

[0080] Weighing bodies 607 are installed at the four corners of the weighing sliding sleeve 601. After contacting and firmly engaging with the supporting side plate, they can weigh the top box 202 and the materials inside the top box 202.

[0081] Furthermore, both the lifting hydraulic cylinder 605 and the side hydraulic cylinder 405 are connected to the same hydraulic system, which can drive the telescopic rods of the lifting hydraulic cylinder 605 and the side hydraulic cylinder 405 to move respectively.

[0082] The specific structures of the rotatable heating component 8 and the positive pressure blowing component 9 are as follows: Figure 13 and Figure 14 As shown, the heating chambers 801 are symmetrically connected to the inner bottom of the sludge collection hopper 203. Each set of heating chambers 801 has a pneumatic chamber 803 fixed on its outer bottom surface. A heating shaft seat 802 is installed between the bottom of the heating chamber 801 and the pneumatic chamber 803. The heating shaft 804 is rotatably connected in the heating shaft seat 802. A bottom cover 806 is attached to the bottom opening of the pneumatic chamber 803. The bottom end of the heating shaft 804 is rotatably connected in the bottom cover 806. The pneumatic impeller 807 is inserted and fixed in the heating shaft 804 and is located in the inner cavity of the pneumatic chamber 803.

[0083] Each set of heating shafts 804 has an array of inclined heating rods 805 installed at its top end, and the heating rods 805 do not interfere with the filter bag 305.

[0084] An inclined drain pipe 808 is connected between the inner wall of each heating chamber 801 and the wall of the drain pipe 204, so that the sewage in the heating chamber 801 can be discharged to the drain pipe 204 through the drain pipe 808.

[0085] The two side walls of the pneumatic cavity 803 are respectively connected to an inlet pipe 809 and an outlet pipe 810, and the outlet pipe 810 and the inlet pipe 809 are directly opposite each other. Compressed air can be introduced into the inner cavity of the pneumatic cavity 803 through the inlet pipe 809 and the outlet pipe 810 to drive the rotation of the pneumatic impeller 807.

[0086] The pneumatic impeller 807 can drive the rotation of the array of heating rods 805 by heating the rotating shaft 804. The rotation of the heating rods 805 can not only directly improve the drying efficiency, but also drive the air flow, so that the heat flow can evenly contact the mud and water mixture in the filter bag 305, indirectly improving the drying efficiency again.

[0087] The top support 901 is symmetrically fixed on the middle of the top two sides of the top of the top box 202. Each set of top supports 901 has an air pipe sleeve 902 that is inclined towards the inner cavity of the top box 202. A compressed air pipe can be inserted into the air pipe sleeve 902. After the compressed air pipe is connected from the air outlet pipe 810, it can be inserted into the two sides directly above the filter bag 305 through the air pipe sleeve 902.

[0088] By directly blowing compressed air onto the filter bag 305, the purpose of dehydration can be achieved by squeezing the filter bag with compressed gas during the dehydration and drying process. After the dehydration and drying process is completed and the filter bag 305 is opened downwards, the purpose of air vibration and mud removal can also be achieved, so that the dehydrated and dried mud can be quickly separated from the filter bag 305.

[0089] Preferably, to improve the error-proofing effect of the weighing slide sleeve 601 movement, a side insert post component 7 is connected between the main body of the side hydraulic cylinder 405 and the side frame of the weighing slide sleeve 601. The insert sleeves 701 are symmetrically fixed at the bottom center of the side frame of the weighing slide sleeve 601. The top of the main body of each set of side hydraulic cylinders 405 is fixed with an insert post 702. When the weighing slide sleeve 601 is in the downward non-weighing position, the side hydraulic cylinder 405 can only move after the side latch 407 rotates and the inner latch 408 disengages from the side latch 401. The movable insert 702 is completely disengaged from the insert sleeve 701; that is, when the weighing slide sleeve 601 is in a downward non-weighing position, the side hydraulic cylinder 405 drives the side buckle 407 to rotate, so that the inner clamping platform 408 and the side clamping plate 401 are engaged and pressed into place. Since the insert 702 is inserted into the insert sleeve 701 at the bottom of the weighing slide sleeve 601, the weighing slide sleeve 601 cannot move freely upward when the top box 202 and the bottom shell 101 are safely and stably connected. This achieves the error prevention effect of moving the weighing slide sleeve 601.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
