Description

Technical Field

[0001] This invention relates to the field of sewage pumps, and more particularly to a cutting pump for sewage treatment. Background Technology

[0002] A cutting pump, also known as a cutting pump or double-blade cutting pump, is a type of sewage pump used to treat wastewater containing fibers and hard solids. It primarily treats wastewater containing long fibers, bags, belts, straw, rags, and other debris. The high-speed rotating impeller or cutting device pulverizes the debris before discharge. The working principle of a cutting pump is based on the synergistic effect of centrifugal force generated by high-speed rotation and the cutting device. The motor drives the impeller to rotate at high speed, creating a vacuum at the center of the impeller, drawing in wastewater. Debris in the wastewater (such as long fibers and rags) enters the pump body and is pulverized by the cutting blades on the impeller edge or a specially designed rotor-stator structure. The pulverized debris is then discharged with the water flow through the outlet pipe, achieving clog-free sewage discharge. Cutting pumps are widely used in urban sewage discharge, rainwater harvesting systems, construction site sludge discharge; industrial wastewater treatment in chemical, paper, and cement plants, and discharge of wastewater containing solid particles; livestock farm wastewater discharge, river dredging, and biogas residue / slurry pumping; wastewater discharge from hospitals, hotels, and high-rise buildings; and sewage lifting from household septic tanks and basements.

[0003] Cutting pumps are widely used in wastewater treatment. When transporting wastewater, they are used to process impurities such as fibers and hard solids, cutting long fibers (such as cloth strips and grass stems) and hard particles (such as gravel and plastic sheets) in wastewater into smaller particles to prevent pipe blockage. The cut wastewater is easier to pump. In the Chinese utility model patent "Announcement No.: CN204755324U, Name: Wastewater Cutting Pump", the moving and fixed blades slide against each other to quickly cut flexible materials entering the inlet through the mutual sliding motion of the blades and the pump casing. However, in the above application and the prior art, each cut is an independent cut, that is, each cut is carried out quickly and individually in a separate chamber. However, the single cut effect is poor. The material that cannot be cut off in a single cut enters the pump body directly, which can easily cause the pump body to become entangled, increase the number of times the cutting pump is repaired, and affect the normal use of the cutting pump. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect of poor cutting effect in the prior art and to provide a cutting pump for sewage treatment.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This invention provides a cutting pump for sewage treatment, comprising an upper pump housing and a lower pump housing, wherein the upper pump housing and the lower pump housing are connected to each other.

[0007] The pump includes a drive motor and a cutting mechanism. The drive motor is installed in the inner cavity of the upper housing of the pump. The output end of the drive motor is connected to the cutting mechanism via a transmission shaft. The cutting mechanism is located in the inner cavity of the lower housing of the pump. The drive motor drives the cutting mechanism to run, and the cutting mechanism performs the cutting operation.

[0008] The cutting mechanism includes a moving cutting disc and a stationary cutting disc. The moving cutting disc is connected to one end of a drive shaft, and the other end of the drive shaft is connected to the output end of a drive motor. The stationary cutting disc is located below the moving cutting disc. The moving cutting disc and the stationary cutting disc work together to cut the material.

[0009] In this technical solution, a static cutting disc and a dynamic cutting disc are used to cut the material. The quincunx design of the static cutting disc allows the dynamic cutting disc to cut the material continuously, avoiding poor cutting effect in a single cut, which would cause long material to enter the pump body. This prevents entanglement and damage to the cutting pump, reduces the number of times the cutting pump needs to be repaired, and improves the efficiency of liquid transportation in sewage treatment.

[0010] Preferably, the static cutting disc is detachably connected to the inlet of the pump lower housing via multiple mounting bolts.

[0011] In this technical solution, the static cutting disc can be disassembled and maintained by removing and installing bolts.

[0012] Preferably, the cross-section of the static cutting disc has a plum blossom-shaped structure.

[0013] In this technical solution, the plum blossom-shaped design of the static cutting disc enables the dynamic cutting disc to continuously cut the material.

[0014] Preferably, one end of the drive shaft is connected to the drive shaft via an adaptive component, the adaptive component including a connecting outer cylinder, the top end of the connecting outer cylinder being connected to the bottom end of the drive shaft;

[0017] The top of the sliding plate is connected to an elastic reset member, and the top of the elastic reset member is connected to the top of the inner cavity of the outer cylinder.

[0018] In this technical solution, an adaptive component is used to make the moving cutting disc move upward adaptively when it encounters a material that is difficult to cut, thereby increasing the gap between the moving cutting disc and the stationary cutting disc, allowing the material to pass through and avoiding damage to the moving cutting disc or the stationary cutting disc.

[0019] Preferably, a plurality of positioning posts arranged in a circular array are provided at the inner cavity of the connecting outer cylinder, and the two ends of the positioning posts are respectively connected to the top and bottom of the inner cavity of the connecting outer cylinder;

[0020] The surface of the positioning post is slidably connected to the sliding plate.

[0021] In this technical solution, the movement trajectory of the sliding plate is limited by the positioning column.

[0022] Preferably, the cutting mechanism further includes an auxiliary component disposed below the stationary cutting disc. The auxiliary component includes a connecting shaft, the top end of which passes through the center of the stationary cutting disc and connects to the bottom end of the mounting shaft.

[0023] A cutting blade is connected to the bottom end of the connecting shaft;

[0024] An annular partition support is provided on the outer side of the cutting blade, and the top of the annular partition support is connected to the bottom surface of the pump lower housing.

[0025] In this technical solution, the material is pre-cut by auxiliary components, which further improves the cutting effect and reduces the probability of material entanglement in the pump body.

[0026] Preferably, a heat dissipation mechanism is provided on the outside of the drive motor, and the heat dissipation mechanism is located in the inner cavity of the pump housing;

[0027] The heat dissipation mechanism includes a liquid cooling component, the liquid cooling component includes a storage box, and a plurality of fixing posts are connected to the side of the storage box. The end of the fixing posts away from the storage box is connected to the inner wall of the pump housing.

[0028] A circulation pump is connected to the side of the storage box. The inlet of the circulation pump is connected to the inner cavity of the storage box, and the outlet of the circulation pump is connected to the circulation liquid pipe.

[0029] One end of the circulating liquid pipe, away from the circulating pump, is connected to one end of the spiral cooling pipe, which covers the outer surface of the drive motor.

[0030] The end of the spiral cooling pipe away from the first circulating liquid pipe is connected to the second circulating liquid pipe, and the end of the second circulating liquid pipe away from the spiral cooling pipe is connected to one side of the storage box.

[0031] In this technical solution, a heat dissipation mechanism is used to dissipate heat from the drive motor, preventing heat damage to the drive motor and making the drive motor more energy-efficient.

[0032] Preferably, the heat dissipation mechanism further includes an air-cooling component, which includes a cooling fan, and the side of the cooling fan is connected to the inner wall of the pump housing.

[0033] A spiral guide plate frame is provided below the cooling fan. The spiral guide plate frame is located outside the drive motor, and the outer side of the spiral guide plate frame is connected to the inner wall of the pump housing.

[0034] In this technical solution, an air-cooling component is used to cool the drive motor.

[0035] Preferably, the air-cooling assembly further includes a fixed circulating air duct and a movable circulating air duct. The end of the fixed circulating air duct away from the movable circulating air duct is connected to the lower side of the upper side of the pump housing, and the end of the movable circulating air duct away from the fixed circulating air duct is connected to the upper side of the upper side of the pump housing. The connection between the movable circulating air duct and the upper side of the pump housing is located above the cooling fan.

[0036] The ends of both the fixed and mobile circulating air ducts that are close to each other are threadedly connected to the inner wall of the threaded sleeve.

[0037] In this technical solution, airflow is circulated through structures such as fixed and movable circulating air ducts, preventing external liquid from entering the pump housing.

[0038] Preferably, a drying component is provided at the connection between the fixed circulating air duct and the upper housing of the pump, and the drying component is installed on the inner wall of the upper housing of the pump;

[0039] The drying assembly includes a placement mesh shell connected to the inner wall of the pump housing, and drying particles are placed inside the placement mesh shell;

[0040] The output end of the drive motor is connected to a plurality of follower columns. The end of the follower column away from the drive motor is connected to a mounting frame. The inner wall of the mounting frame is connected to a rail, and a swaying plate is slidably fitted on the surface of the rail.

[0041] Both the upper and lower sides of the swaying plate are connected to elastic connectors, and the end of the elastic connector away from the swaying plate is connected to the inner wall of the mounting frame.

[0042] A connecting column is connected to one side of the shaking plate, and an agitator is connected to the side of the connecting column away from the shaking plate. The agitator is located in the inner cavity of the mesh shell.

[0043] The inner side of the placement mesh shell has a wavy opening, and the connecting column passes through the wavy opening through the inner side of the placement mesh shell and extends to the inner cavity of the placement mesh shell.

[0044] In this technical solution, the airflow inside the pump housing is dried by a drying component to prevent steam generated by alternating hot and cold temperatures from damaging the drive motor.

[0045] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0046] The positive and progressive effects of this invention are as follows:

[0047] This invention uses a static cutting disc in conjunction with a dynamic cutting disc to cut materials. The plum blossom-shaped design of the static cutting disc allows the dynamic cutting disc to cut materials continuously, avoiding poor cutting results from a single cut that could lead to long pieces of material entering the pump body. This also prevents entanglement and damage to the cutting pump, reduces the frequency of pump maintenance, improves the efficiency of liquid transport during wastewater treatment, and facilitates wastewater treatment.

[0048] Meanwhile, the moving cutting disc, in conjunction with the lower housing of the pump, can transport liquid, making it easier for the liquid to flow within the cutting pump. This avoids the rotation of the moving cutting disc from obstructing the flow of the liquid, making it easier to transport the liquid, improving the efficiency of wastewater treatment, and making the cutting pump more energy-efficient when in use.

[0049] Furthermore, an auxiliary component is installed. When the material enters the lower housing of the pump, the auxiliary component first performs preliminary crushing on the material. Combined with the cutting effect of the moving and stationary cutting discs, the material is cut into smaller particles, improving the cutting effect, reducing the probability of the cutting pump being blocked, and ensuring the normal operation of sewage treatment.

[0050] Furthermore, the drive motor is cooled by liquid cooling and air cooling components to prevent heat from accumulating inside the pump housing and damaging the drive motor. This makes the drive motor more energy-efficient during use, extends its service life, reduces the number of times the cutting pump needs to be shut down for maintenance, and thus improves the efficiency of liquid delivery.

[0051] Furthermore, the airflow inside the pump housing is dried by the drying component, which effectively prevents water vapor generated by alternating hot and cold temperatures from damaging the drive motor. Attached Figure Description

[0087] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0088] Figures 1 to 19 The diagram shown is a structural schematic of an embodiment of the cutting pump of the present invention.

[0089] Example 1

[0090] like Figures 1 to 7 As shown, the cutting pump for sewage treatment includes an upper pump housing 1 and a lower pump housing 2, which are connected to each other.

[0091] The pump consists of a drive motor 3 and a cutting mechanism. The drive motor 3 is installed in the inner cavity of the upper housing 1 of the pump. The output end of the drive motor 3 is connected to the cutting mechanism via a transmission shaft 4. The cutting mechanism is located in the inner cavity of the lower housing 2 of the pump. The drive motor 3 drives the cutting mechanism to run and performs the cutting operation using the cutting mechanism.

[0092] The cutting mechanism includes a moving cutting disc 5 and a stationary cutting disc 6. The moving cutting disc 5 is connected to one end of a drive shaft 4, and the other end of the drive shaft 4 is connected to the output end of a drive motor 3. The stationary cutting disc 6 is located below the moving cutting disc 5. The moving cutting disc 5 and the stationary cutting disc 6 work together to cut the material.

[0093] In this technical solution, the material is cut by the static cutting disc 6 in conjunction with the moving cutting disc 5. The plum blossom-shaped design of the static cutting disc 6 allows the moving cutting disc 5 to cut the material continuously, avoiding poor cutting effect in a single cut, which would cause long material to enter the pump body, prevent entanglement and damage to the cutting pump, reduce the number of times the cutting pump needs maintenance, improve the efficiency of liquid transportation, and improve the efficiency of sewage treatment.

[0094] The static cutting disc 6 is detachably connected to the inlet of the pump lower housing 2 by multiple disassembly bolts 7.

[0095] In this technical solution, the static cutting disc 6 can be disassembled and maintained by means of the disassembly bolt 7.

[0096] The cross-section of the static cutting disc 6 is a plum blossom-shaped structure.

[0097] In this technical solution, the plum blossom-shaped design of the static cutting disc 6 enables the dynamic cutting disc 5 to continuously cut the material.

[0098] In operation, the drive motor 3 drives the transmission shaft 4 to rotate, which in turn drives the moving cutting disc 5 to rotate. The rotating moving cutting disc 5, in conjunction with the stationary cutting disc 6, cuts the material passing through. Because the stationary cutting disc 6 has a quincunx-shaped structure, the gap between the moving cutting disc 5 and the stationary cutting disc 6 is continuous and of varying size, making the cutting chamber between the moving cutting disc 5 and the stationary cutting disc 6 continuous. This allows the moving cutting disc 5 and the stationary cutting disc 6 to cut the material continuously, performing multiple cuts to avoid leaving material uncut in a single cut, preventing incompletely cut material from entering the cutting pump, avoiding damage to the cutting pump due to entanglement, extending the service life of the cutting pump, ensuring the normal operation of wastewater treatment, and improving the efficiency of wastewater treatment.

[0099] One end of the drive shaft 4 is connected to the drive shaft 4 via an adaptive component 8. The adaptive component 8 includes a connecting outer cylinder 81, the top end of which is connected to the bottom end of the drive shaft 4.

[0100] A sliding plate 82 is slidably disposed in the inner cavity of the connecting outer cylinder 81, and a rotating column 83 is connected to the bottom of the sliding plate 82. The surface of the rotating column 83 is slidably connected through the bottom surface of the connecting outer cylinder 81.

[0101] The bottom end of the rotating column 83 is connected to a mounting shaft 84, and the surface of the mounting shaft 84 is connected to the center of the moving cutting disc 5.

[0102] The top of the sliding plate 82 is connected to an elastic reset member 85, and the top end of the elastic reset member 85 is connected to the top of the inner cavity of the outer cylinder 81.

[0103] In this technical solution, the adaptive component 8 is used to make the moving cutting disc 5 move upward adaptively when it encounters a material that is difficult to cut, thereby increasing the gap between the moving cutting disc 5 and the stationary cutting disc 6, allowing the material to pass through and avoiding damage to the moving cutting disc 5 or the stationary cutting disc 6.

[0104] The inner cavity of the connecting outer cylinder 81 is provided with a plurality of positioning posts 86 arranged in a ring array, and the two ends of the positioning posts 86 are respectively connected to the top and bottom of the inner cavity of the connecting outer cylinder 81.

[0105] The surface of the positioning post 86 is slidably connected to the sliding plate 82.

[0106] In this technical solution, the movement trajectory of the sliding plate 82 is limited by the positioning post 86.

[0107] When encountering a hard object that the moving cutting disc 5 and the stationary cutting disc 6 cannot cut, the hard object enters the gap between the moving cutting disc 5 and the stationary cutting disc 6, squeezing the moving cutting disc 5. At this time, the moving cutting disc 5 moves upward, thereby driving the mounting shaft 84 to move upward, which in turn drives the rotating column 83 to move in the same direction. When the rotating column 83 moves, it drives the sliding plate 82 to move in the same direction along the positioning column 86, compressing the elastic reset member 85. At this time, the gap between the moving cutting disc 5 and the stationary cutting disc 6 increases, allowing the hard material to enter the lower housing 2 of the pump through the gap between the moving cutting disc 5 and the stationary cutting disc 6, and then be discharged from the cutting pump with the liquid.

[0108] After the hard material passes between the moving cutting disc 5 and the stationary cutting disc 6, the squeezing force on the moving cutting disc 5 disappears. At this time, under the action of the elastic reset member 85, the elastic reset member 85 automatically resets, thereby driving the sliding plate 82 and the mounting shaft 84 and other structures to return to their initial positions, and then causing the moving cutting disc 5 to return to its initial position. The moving cutting disc 5 and the stationary cutting disc 6 are then used to continue cutting the material.

[0109] Example 2

[0110] As one embodiment of this application, such as Figure 8 and Figure 9 As shown, the difference between it and Embodiment 1 is that the cutting mechanism further includes an auxiliary component 9, which is disposed below the stationary cutting disc 6. The auxiliary component 9 includes a connecting shaft 91, the top end of which passes through the center of the stationary cutting disc 6 and is connected to the bottom end of the mounting shaft 84.

[0111] The bottom end of the connecting shaft 91 is connected to a cutting blade 92;

[0112] An annular partition support 93 is provided on the outer side of the cutting blade 92, and the top of the annular partition support 93 is connected to the bottom surface of the pump lower housing 2.

[0113] In this technical solution, the material is pre-cut by the auxiliary component 9, which further improves the cutting effect and reduces the probability of material entanglement in the pump body.

[0114] When the drive shaft 4 rotates, it drives the connecting outer cylinder 81 and the mounting shaft 84 to rotate, thereby driving the connecting rotating shaft 91 to rotate, which in turn drives the cutting blade 92 to rotate. The cutting blade 92 is used to pre-cut the material entering the stationary cutting disc 6 to assist the cutting of the moving cutting disc 5 and the stationary cutting disc 6, further improving the cutting effect, reducing the efficiency of material clogging the cutting pump, and ensuring the normal operation of sewage treatment.

[0115] Example 3

[0116] As one embodiment of this application, such as Figures 11 to 14 As shown, its difference from the brackets in other embodiments is that a heat dissipation mechanism is provided on the outside of the drive motor 3, and the heat dissipation mechanism is located in the inner cavity of the pump upper housing 1;

[0117] The heat dissipation mechanism includes a liquid cooling assembly 10, which includes a storage box 101. A plurality of fixing posts 102 are connected to the side of the storage box 101, and the end of the fixing post 102 away from the storage box 101 is connected to the inner wall of the pump upper housing 1.

[0118] An inlet / outlet assembly is installed at the storage box 101 for adding coolant into the storage box 101.

[0119] A circulation pump 103 is connected to the side of the storage box 101. The inlet end of the circulation pump 103 is connected to the inner cavity of the storage box 101, and the outlet end of the circulation pump 103 is connected to one end of the circulation liquid pipe 104.

[0120] The end of the circulating liquid pipe 104 away from the circulating pump 103 is connected to one end of the spiral cooling pipe 105, and the spiral cooling pipe 105 covers the outer surface of the drive motor 3.

[0121] The end of the spiral cooling pipe 105 away from the first circulating liquid pipe 104 is connected to the second circulating liquid pipe 106, and the end of the second circulating liquid pipe 106 away from the spiral cooling pipe 105 is connected to one side of the storage box 101.

[0122] In this technical solution, a heat dissipation mechanism is used to dissipate heat from the drive motor 3, avoiding heat damage to the drive motor 3 and making the drive motor 3 more energy-efficient.

[0123] During use, the coolant in the storage box 101 circulates between the storage box 101, the circulation pump 103, the first circulation pipe 104, the spiral cooling pipe 105 and the second circulation pipe 106 under the action of the circulation pump 103. When the coolant flows in the spiral cooling pipe 105, it gets close to the drive motor 3 and heats up the drive motor 3.

[0124] The heat dissipation mechanism also includes an air-cooling component 11, which includes a cooling fan 111. The side of the cooling fan 111 is connected to the inner wall of the pump housing 1.

[0125] A spiral guide plate frame 115 is provided below the cooling fan 111. The spiral guide plate frame 115 is located outside the drive motor 3, and the outer side of the spiral guide plate frame 115 is connected to the inner wall of the pump upper housing 1.

[0126] The spiral guide plate frame 115 has a trapezoidal structure with a higher outer surface and a lower inner surface. In use, the inclined surface of the spiral guide plate frame 115 guides the airflow to the drive motor 3, thereby effectively improving the heat dissipation effect of air cooling.

[0127] In this technical solution, the air-cooling component 11 is used to cool the drive motor 3.

[0128] The air-cooling assembly 11 also includes a fixed circulating air duct 112 and a movable circulating air duct 113. The end of the fixed circulating air duct 112 away from the movable circulating air duct 113 is connected to the lower side of the upper side of the pump housing 1. The end of the movable circulating air duct 113 away from the fixed circulating air duct 112 is connected to the upper side of the upper side of the pump housing 1. The connection between the movable circulating air duct 113 and the upper side of the pump housing 1 is located above the cooling fan 111.

[0129] The ends of the fixed circulating air duct 112 and the mobile circulating air duct 113 that are close to each other are threadedly connected to the inner wall of the threaded sleeve 114.

[0130] The pump housing 1 is composed of upper and lower frame shells, which are detachably connected by bolts. The upper frame shell is connected to the movable circulating air duct 113, and the lower frame shell is connected to the fixed circulating air duct 112.

[0131] The fixed circulating air duct 112 and the mobile circulating air duct 113 are both provided with external threads at opposite ends, and the threaded sleeve 114 is threadedly connected to the fixed circulating air duct 112 and the mobile circulating air duct 113 respectively through external threads.

[0132] The upper and lower parts of the pump housing 1 can be disassembled. When disassembling, first rotate the threaded sleeve 114 so that the threaded sleeve 114 is away from the fixed circulation air pipe 112 or the moving circulation air pipe 113, and then disassemble the upper frame.

[0133] The installation can be done in the opposite way.

[0134] In this technical solution, the airflow is circulated by structures such as the fixed circulating air duct 112 and the movable circulating air duct 113, which prevents external liquid from entering the pump housing 1.

[0135] In use, the cooling fan 111 blows air onto the drive motor 3 to achieve air cooling, extend the service life of the drive motor 3, and thus extend the service life of the cutting pump and improve the efficiency of sewage treatment.

[0136] It is worth noting that, under the action of the spiral guide plate frame 115, the airflow is guided to drive the motor 3, thereby improving the effect of air cooling.

[0137] The airflow re-enters the pump housing 1 through the fixed circulation duct 112, the threaded sleeve 114 and the movable circulation duct 113, thus completing the airflow circulation.

[0138] Example 4

[0139] As one embodiment of this application, such as Figures 10 to 12 , Figures 15 to 19 As shown, a drying component 12 is provided at the connection between the fixed circulating air duct 112 and the upper housing 1 of the pump, and the drying component 12 is installed on the inner wall of the upper housing 1 of the pump.

[0140] The drying assembly 12 includes a mesh housing 121, which is connected to the inner wall of the upper housing 1 of the pump, and drying particles are placed inside the mesh housing 121.

[0141] The output end of the drive motor 3 is connected to a plurality of follower columns 122. The end of the follower column 122 away from the drive motor 3 is connected to a mounting frame 123. The inner wall of the mounting frame 123 is connected to a track bar 124. A rocking plate 125 is slidably sleeved on the surface of the track bar 124.

[0142] The upper and lower sides of the swaying plate 125 are connected to elastic connectors 126, and the end of the elastic connector 126 away from the swaying plate 125 is connected to the inner wall of the mounting frame 123.

[0143] A connecting post 127 is connected to one side of the shaking plate 125, and an agitator 128 is connected to the side of the connecting post 127 away from the shaking plate 125. The agitator 128 is located in the inner cavity of the mesh shell 121.

[0144] The inner side of the mesh housing 121 is provided with a wavy opening 13, and the connecting post 127 passes through the wavy opening 13 through the inner side of the mesh housing 121 and extends to the inner cavity of the mesh housing 121.

[0145] In this technical solution, the airflow inside the pump housing 1 is dried by the drying component 12 to prevent the steam generated by alternating hot and cold temperatures from damaging the drive motor 3.

[0146] During air cooling, the airflow passes through the mesh shell 121, is dehumidified by the dry particles inside the mesh shell 121, and then enters the fixed circulation duct 112 for circulation.

[0147] At the same time, the output end of the drive motor 3 drives the follower column 122 to rotate, thereby driving the mounting frame 123, track bar 124, swaying plate 125 and connecting column 127 to rotate, and then driving the stirring frame 128 to rotate.

[0148] When the connecting column 127 is running, it rotates within the corrugated opening 13. At this time, under the action of the elastic connector 126, the connecting column 127 moves up and down with the corrugated opening 13, thereby driving the swaying plate 125 to sway up and down along the track 124, which in turn drives the stirring frame 128 to slide up and down. This allows the stirring frame 128 to move up and down while rotating, and the stirring frame 128 is used to stir the dry particles placed in the mesh shell 121, so that the airflow can fully contact the dry particles, thereby improving the moisture absorption and dehumidification effect.

[0149] A turning bar 14 is connected to one side of the stirring frame 128.

[0150] When the stirring frame 128 rotates, it drives the turning bar 14 to rotate, and the turning bar 14 assists the stirring frame 128 in drying the dry particles placed in the mesh shell 121.

[0151] A rolling sleeve 15 is rotatably connected to the surface of the connecting column 127, and the surface of the rolling sleeve 15 contacts the wall of the wavy opening 13 on the side of the mesh shell 121.

[0152] In use, the rolling sleeve 15 rotates along with the connecting column 127. At this time, under the action of the corrugated opening 13 and the elastic connector 126, the rolling sleeve 15 moves up and down with the shape of the corrugated opening 13, thereby driving the connecting column 127 and the stirring frame 128 to move up and down. This causes the stirring frame 128 to shake up and down while rotating, so that the stirring frame 128 and the turning bar 14 can fully turn and stir the dry particles placed in the mesh shell 121, so that the dry particles can fully contact the circulating airflow to obtain a better moisture absorption effect.

[0153] The connections of the upper pump housing 1, the lower pump housing 2, and the drive shaft 4 are all equipped with sealing structures.

[0154] The drying particles placed inside the mesh shell 121 can be made of materials with moisture-absorbing functions, such as activated carbon particles.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
