Description

Technical Field

[0001] This invention relates to a wastewater treatment device, specifically a wastewater treatment device, and relates to the technical field of water source treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] However, existing wastewater treatment devices still have some problems. When adding chemicals to the wastewater tank, most of them are done manually. The manual labor involves splashing chemicals into the storage tank. However, because the storage tank has a large capacity, the area and number of times the chemicals need to be splashed manually are too large, and the amount of chemicals to be added is also large. This leads to a large number of people having to do the chemical splashing work, which increases labor costs.

[0004] To address these issues, some companies have implemented reagent addition procedures. However, the locations of these procedures are relatively fixed, which can lead to excessively high concentrations in certain areas. This makes it difficult for subsequent reagents to dissolve, ultimately reducing the efficiency of wastewater treatment.

[0005] Therefore, how to treat wastewater is a problem that needs to be solved. Summary of the Invention

[0024] The rotating roller is also fitted with a limiting block, and the limiting block is provided with a through hole in the radial direction, as well as another water outlet hole provided on the limiting block, and the water outlet hole is connected to the through hole;

[0025] The connecting seat is connected to the connecting end and the transport pipe respectively.

[0026] In a further embodiment, the measuring unit includes a mounting base connected to a second connecting frame, a mounting bracket disposed on the mounting base, a flipping assembly disposed on the mounting bracket, a measuring cylinder connected to the flipping assembly, a measuring cylinder fixedly connected to the mounting bracket, an adjusting seat connected to the measuring cylinder, and a connecting pipe symmetrically mounted on the adjusting seat.

The inner and outer cylinders are movably connected. The bottom of the inner cylinder is also provided with a drain pipe connected to the reagent storage tank.

[0031] In a further embodiment, the moving unit includes a drive motor fixedly mounted on the movable base, a drive gear disposed at the output end of the drive motor, a double gear and a driven gear disposed on the movable base, a plurality of drive wheels disposed on the movable base, a first drive chain for connecting the drive gear and the double gear, and a second drive chain for connecting the double gear and the driven gear.

[0032] The movable base is also equipped with a drive roller, with two drive wheels sleeved on the drive roller, and the driven gear located at one end of the drive roller.

[0033] A method for operating the above-mentioned wastewater treatment device includes the following steps:

[0034] S1: When wastewater treatment is required, the wastewater is first transferred to a storage tank, then raw materials are added to the granule feeding unit or solution feeding unit, and then the appropriate reagents are selected according to the actual situation.

[0035] S2: When granular agents are selected for dispensing, different agents are placed in the holding tank according to the requirements. The agents can then enter the dispensing device through the discharge port. The dispensing motor starts working, and the moving dispensing motor drives the dispensing shaft to rotate. The moving dispensing shaft drives the dispensing gear to rotate, and the agents fall into the teeth of the dispensing gear. With the cooperation of the dispensing gear, the granular agents can be transferred to the discharge pipe. Then, under its own gravity, the agents can fall into the wastewater, completing the agent addition work.

[0036] S3: When liquid agent is selected for dispensing, the agent is added to the agent storage tank. Then, the water pump installed in the agent storage tank allows the agent to enter the connection end. The agent can then pass through the isolated injection section, while the remaining injection section is closed. The liquid solution can then pass through the injection section and the transport pipe, and then be sprayed out from the free end of the outlet pipe.

[0037] S4: While performing step S3, the flipping cylinder starts working, which in turn drives the flipping block to move. The moving flipping block then drives the adjusting shaft to move, which in turn drives the limit seat to move, thereby adjusting the position of the measuring cylinder. Then the measuring cylinder starts working, which positions the outlet of the connecting pipe above the measuring cylinder, allowing the addition of reagent to the measuring cylinder. This causes a change in the pressure detector value. After a predetermined time, the telescopic cylinder starts working, which in turn drives the rotating roller to work. The rotating roller blocks the outlet of the connecting end, preventing the reagent from entering the measuring cylinder. At this time, the pressure detector value replaces the reagent addition efficiency, allowing the injection efficiency of the remaining injection section to be determined. The reagent in the inner cylinder flows to the reagent storage tank through the drain pipe.

[0038] S5: Then the telescopic cylinder in the remaining injection section starts to work, which allows it to be in the open state, and the agent can flow out from the outlet pipe. Since the trace element content in the wastewater has been tested before treatment, the amount of agent to be added can be calculated. When the predetermined addition value is reached, the water pump stops working, and the agent addition work is completed.

[0039] During the water pump shutdown process, due to inertia and other factors, it may continue to operate for a certain period of time, thus continuing to deliver chemicals. At this time, the telescopic cylinder starts working, which in turn drives the rotating roller to move. Then, the drive cylinder starts working, which in turn drives the drive seat to work. The moving drive seat then drives the sealing gasket to work, which moves the sealing gasket away from the connecting seat. Excess chemicals can then be stored in this location. When trace elements that have not been completely removed are still present in the wastewater, the movement of the drive cylinder and the rotating roller can add chemicals from the storage tank back into the wastewater for a small-scale secondary chemical addition. Conversely, when the trace elements in the wastewater are completely removed, the stored chemicals can be used in the next wastewater treatment.

[0040] S6: During the process of adding the medicine, the drive motor starts to work, and the moving drive motor can make the double gear start to rotate with the cooperation of the first drive chain. The moving double gear can make the driven gear start to move with the cooperation of the second drive chain. The moving driven gear can drive the drive wheel located on the same drive roller to start to move, thereby enabling the movable base to move above the water storage tank, thus completing the medicine moving and adding work.

[0041] S7: During the process of adding the agent, the crushing motor starts to work, and the moving crushing motor can crush the suspended matter. Then, under the action of the pressure roller, it is brought below the water surface, so that some of the suspended matter can sink to the bottom. Then the collecting motor starts to work, and the moving collecting motor can drive the first bevel gear to rotate. The moving first bevel gear can drive the second bevel gear to move, which can drive the belt conveyor to move, thus completing the collection of the remaining suspended matter.

[0042] Beneficial Effects: This invention discloses a wastewater treatment device. To treat wastewater, the device includes a granule dispensing unit and a solution dispensing unit. A reagent gear in the granule dispensing unit ensures that the amount of reagent added during rotation is consistent and uniform. Controlling the rotation speed of the feeding motor adjusts the reagent addition rate, ensuring uniform distribution. The solution dispensing unit and measuring unit control the dosage, measuring the amount added within a predetermined time and using this as the injection rate. During addition, a movable base and moving unit adjust the reagent addition position, preventing excessive concentration in certain areas and reducing the dissolution rate. The blades on the crushing roller in the collection assembly further accelerate the mixing process. Attached Figure Description

Detailed Implementation

[0052] Based on the applicant's research and analysis, the reason for this problem (excessively high concentration in some areas, leading to difficulty in dissolving subsequent reagents) is that the existing reagent addition positions are relatively fixed, resulting in excessively high concentrations in some areas, making subsequent reagents difficult to dissolve, and consequently reducing the efficiency of wastewater treatment. To complete the wastewater treatment, this invention includes a granule dispensing unit and a solution dispensing unit. A reagent gear in the granule dispensing unit ensures that the amount of reagent added during a certain rotation angle is consistent, or evenly distributed into the wastewater. Simultaneously, the speed of the dispensing motor is controlled... This allows for adjustment of the drug addition rate, ensuring uniform drug distribution in the wastewater. The solution dispensing and measuring units control the dosage, measuring the amount added within a predetermined time and using this as the injection rate for the injection unit. Furthermore, the movable base and moving unit adjust the drug addition position during the process, preventing excessively high concentrations in certain areas that could slow dissolution. Additionally, the blades on the pulverizing roller in the collection assembly further enhance the mixing effect, accelerating drug dissolution.

When wastewater treatment is required, the wastewater is first transferred to the water storage tank 1, and then raw materials are added to the particle dispensing unit 3 or the solution dispensing unit 4. Then, the appropriate reagent is selected according to the actual situation.

[0055] The pellet dispensing unit 3 includes a dispensing rack 31 connected to the movable base 2, a dispensing component 33 and a protective cover 32 disposed on the dispensing rack 31, and a collection component 34 connected to the protective cover 32; the dispensing component 33 includes a holding box 331 fixedly connected to the dispensing rack 31, a partition plate 333 disposed inside the holding box 331, the partition plate 333 dividing the holding box 331 into two areas, each area having multiple leakage holes, a leakage pipe 332 located in one area and fitted onto the leakage holes, and a collection component 34 disposed on the dispensing rack. A set of dosing devices on the dosing rack 31; one dosing device is used to receive the agent leaking from the leakage hole in one area, and the other dosing device is used to receive the agent leaking from the discharge end of the leakage pipe 332, and then the two agents are added to the wastewater through the dosing devices; the dosing device includes a feeding motor 335 fixedly installed on the dosing rack 31, a dosing shaft 336 located at the output end of the dosing motor, a plurality of dosing gears 337 sleeved on the dosing shaft 336, a plurality of discharge pipes 334 connected to the dosing rack 31, and a discharge pipe 33 connected to the discharge pipes 334. 8; The discharge pipe 338 is located at the bottom of the discharge pipe 334; Through the set dosing gear 337, the granular agent can be evenly dosed into the wastewater, thus preventing the agent concentration in some areas of the wastewater from being too high; When granular agent is selected for dosing, different agents are placed in the holding box 331 according to the requirements, and then the agent can enter the dosing device through the discharge port. Then the dosing motor 335 starts to work, and the moving dosing motor 335 can drive the dosing shaft 336 to start rotating, and the moving dosing shaft 336 can drive the dosing gear 337. 37 starts to rotate, allowing the medicine to fall into the tooth pitch of the dosing gear 337. With the cooperation of the dosing gear 337, the granular medicine can be transferred to the discharge pipe 334. Then, under its own gravity, the medicine can fall into the wastewater, completing the medicine addition work. At the same time, the medicine gear is set to perform the feeding work, so as to ensure that the medicine added at a certain angle is certain or evenly added to the wastewater. By controlling the speed of the dosing motor 335, the medicine addition speed can be adjusted, so that the medicine can be evenly distributed into the wastewater.

[0056] The collection assembly 34 includes a crushing motor 341 and a pressure roller 344 mounted on the protective cover 32, a crushing shaft 342 connected to the output end of the crushing motor 341, a plurality of blades 343 evenly arranged on the crushing shaft 342, a fixed base 345 connected to the protective cover 32, a belt conveyor 3410 mounted on the fixed base 345, a set of collection blades 346 symmetrically mounted on the fixed base 345, a collection motor 347 fixedly connected to the fixed base 345, a first bevel gear 348 connected to the output end of the collection motor 347, and a second bevel gear 349 meshing with the first bevel gear 348; a certain space for placing floating objects exists between one end of the belt conveyor 3410 away from the collection blades 346 and the fixed base 345; the second bevel gear 349 meshes with the belt conveyor 3410. 10.

[0057] The solution dispensing unit 4 includes a first connecting frame 41 and a second connecting frame 42 respectively connected to the dosing rack 31, multiple injection parts 43 disposed on the first connecting frame 41, a transport pipe 45 and a connecting end 44 respectively connected to the injection parts 43, a limiting end 46 connected to the transport pipe 45, and a water outlet pipe 47 disposed on the limiting end 46. The second connecting frame 42 is also provided with at least two limiting pipes 49 and a limiting bolt 410 screwed to the limiting end 46. One injection part 43 is located away from the remaining injection parts 43 and is connected to the measuring unit 6. There is a predetermined gap between the two limiting pipes 49, and the limiting bolt 410 passes through the gap and is screwed to the limiting end 46. By rotating the limiting bolt 410, the limiting end 46 is fixed. The injection unit 43 is fixed on the first connecting frame 41; the connecting ends 44 are respectively connected to the medicine storage tank; the injection unit 43 includes a storage tank 435 and a connecting frame 431 connected to the first connecting frame 41, a hinge seat 432 fixedly installed on the connecting frame 431, a telescopic cylinder 433 movably connected to the hinge seat 432, a connecting piece 436 connected to the output end of the telescopic cylinder 433, and a rotating roller 4310 connected to the connecting piece 436. The storage tank 435 is also provided with a connecting seat 439, and the other end of the storage tank 435 is also provided with a drive cylinder 438, a drive seat 437 provided at the output end of the drive cylinder 438, and a sealing gasket 434 sleeved on the circumference of the drive seat 437; the rotating roller 4310 is located at... The rotating roller 4310 is also fitted with a limiting block, which has a through hole in the radial direction and another water outlet hole on the limiting block, which communicates with the through hole. The connecting seat 439 is connected to the connecting end 44 and the transport pipe 45 respectively. The measuring unit 6 includes a mounting seat 61 connected to the second connecting frame 42, a mounting frame 62 on the mounting seat 61, a flipping component 63 on the mounting frame 62, a measuring cylinder 64 connected to the flipping component 63, a measuring cylinder 65 fixedly connected to the mounting frame 62, an adjusting seat 66 connected to the measuring cylinder 65, and a connecting pipe 67 symmetrically installed on the adjusting seat 66. The flipping assembly 63 includes a flipping cylinder 631 movably connected to the mounting bracket 62, a set of adjusting shafts 633 symmetrically mounted on the mounting bracket 62, a limiting seat 634 connected to one end of the adjusting shafts 633, and a flipping block 632 connected to the other end of one of the adjusting shafts 633; ​​the measuring unit 6 is connected to an independent injection unit 43, and the water outlet pipe 47 in the injection unit 43 is connected to one of the connecting pipes 67; the output end of the flipping cylinder 631 is movably connected to the flipping block 632; the measuring cylinder 64 abuts against the limiting seat 634, and the measuring cylinder 64 has a double-layer structure, wherein a pressure detector is provided between the inner cylinder and the outer cylinder; the inner cylinder and the outer cylinder are movably connected; the bottom of the inner cylinder is also provided with a drain pipe connected to a medicine storage tank;When liquid agents are selected for dispensing, the agent is added to the agent storage tank. A water pump in the tank then pumps the agent into connection 44, where it passes through isolated injection section 43 (which remains closed). The liquid solution then passes through injection section 43 and transport pipe 45, and is ejected from outlet pipe 47. Simultaneously with step S3, the tilting cylinder 631 activates, causing the tilting block 632 to move. The moving tilting block 632 then moves the adjusting shaft 633, which in turn moves the... The limit seat 634 begins to move, thereby adjusting the position of the measuring cylinder 64. Then, the measuring cylinder 65 starts to work, positioning the outlet of the connecting pipe 67 above the measuring cylinder 64, allowing the addition of reagent to the measuring cylinder 64. This causes a change in the pressure detector reading. After a predetermined time, the telescopic cylinder 433 starts to work, driving the rotating roller 4310 to block the outlet of the connecting end 44, thus preventing the reagent from entering the measuring cylinder 64. At this point, the pressure detector reading replaces the reagent addition efficiency, allowing the determination of the injection efficiency of the remaining injection section 43. The medicine in the inner cylinder flows to the medicine storage tank through the drain pipe; then the telescopic cylinder 433 in the remaining injection section 43 starts working, opening it and allowing the medicine to flow out from the outlet pipe 47. Since the trace element content in the wastewater has been tested before treatment, the required amount of medicine can be calculated. When the predetermined addition value is reached, the water pump stops working, and the medicine addition is completed. During the water pump shutdown process, due to inertia and other factors, it may remain in working state for a certain period of time, continuing to deliver medicine. At this time, the telescopic cylinder 433 starts working, driving the rotating roller 431. The system moves, then the drive cylinder 438 starts working, which in turn drives the drive seat 437 to work. The drive seat 437 then drives the sealing gasket 434 to work, thus moving the sealing gasket 434 away from the connecting seat 439. Excess reagent can then be stored in this location. If trace elements are still present in the wastewater, the movement of the drive cylinder 438 and the rotating roller 4310 adds reagent from the storage tank 435 back into the wastewater for a small-scale, secondary reagent addition. Conversely, once the trace elements in the wastewater are completely removed, the stored reagent can be used in the next wastewater treatment.

[0058] The moving unit 5 includes a drive motor 51 fixedly mounted on the movable base 2, a drive gear 52 located at the output end of the drive motor 51, a double gear 53 and a driven gear 54 located on the movable base 2, multiple drive wheels 58 located on the movable base 2, a first drive chain 55 connecting the drive gear 52 and the double gear 53, and a second drive chain 56 connecting the double gear 53 and the driven gear 54; the movable base 2 also has a drive roller, with two drive wheels 58 sleeved on the drive roller, and the driven gear 54 located at one end of the drive roller; during the drug addition process, the drive... When motor 51 starts working, the driving motor 51, in conjunction with the first driving chain 55, causes the double gear 53 to rotate. The double gear 53, in conjunction with the second driving chain 56, causes the driven gear 54 to move. The driven gear 54 then drives the driving wheel 58 located on the same driving roller to move, thereby enabling the movable base 2 to move above the water storage tank 1, thus completing the drug delivery operation. By changing the positions of the granule dispensing unit 3 and the solution dispensing unit 4, the drug delivery area can be changed, thereby preventing the drug concentration in a certain area from being too high, which would cause the drug solution speed to slow down.

[0059] Working Principle Description: When wastewater treatment is required, the wastewater is first transferred to the storage tank 1. Then, raw materials are added to the granule dispensing unit 3 or the solution dispensing unit 4, and the appropriate reagent is selected according to the actual situation. When granular reagents are selected for dispensing, different reagents are placed in the holding box 331 according to the requirements. The reagents can then enter the dosing device through the discharge port. The dispensing motor 335 starts working, which drives the dosing shaft 336 to rotate. The rotating dosing shaft 336 drives the dosing gear 337 to rotate, and the reagents fall into the teeth of the dosing gear 337. With the cooperation of the dosing gear 337, the granular reagents are dispensed. The agent is transferred to the discharge pipe 334, and then falls into the wastewater under its own gravity, completing the agent addition. Simultaneously, a feeding mechanism is used to ensure that the agent added to the wastewater is consistent and evenly distributed as it rotates a certain angle. The speed of the feeding motor 335 is controlled to adjust the agent addition speed, ensuring even distribution of the agent into the wastewater. When liquid agents are selected for addition, the agent is added to the agent storage tank. A water pump in the tank then pumps the agent into the connection end 44, where it passes through an isolated injection section 43 (which remains closed). The liquid solution... The liquid can pass through the injection section 43 and the transport pipe 45, and then be sprayed out from the free end of the outlet pipe 47; while performing step S3, the tilting cylinder 631 starts to work, and the moving tilting cylinder 631 can drive the tilting block 632 to start to move, and then the moving tilting block 632 can drive the adjusting shaft 633 to start to move, and then the moving adjusting shaft 633 can drive the limiting seat 634 to start to move, thereby adjusting the position of the measuring cylinder 64. Then the measuring cylinder 65 starts to work, thereby positioning the outlet of the connecting pipe 67 above the measuring cylinder 64, thereby adding the reagent into the measuring cylinder 64, and thus changing the value of the pressure detector. After a predetermined time, the telescopic cylinder 433 starts to work, and then the moving telescopic cylinder 435... Cylinder 433 drives the rotating roller 4310 to start working, and the rotating roller 4310 blocks the outlet of the connecting end 44, thereby preventing the agent from entering the measuring cylinder 64. At this time, the value of the pressure detector replaces the agent addition efficiency, and the injection efficiency of the remaining injection section 43 can be obtained. The agent in the inner cylinder flows to the agent storage tank through the drain pipe. Then, the telescopic cylinder 433 in the remaining injection section 43 starts working, which opens it, allowing the agent to flow out from the outlet pipe 47. Since the trace element content in the wastewater has been tested before treatment, the amount of agent to be added can be calculated. When the predetermined addition value is reached, the water pump stops working, and the agent addition work is completed.During the water pump shutdown process, due to inertia and other factors, it may remain operational for a certain period, continuing to deliver chemicals. At this time, the telescopic cylinder 433 activates, driving the rotating roller 4310. Then, the drive cylinder 438 activates, which in turn drives the drive seat 437. The moving drive seat 437 then drives the sealing gasket 434, moving it away from the connecting seat 439. Excess chemicals are stored in this location. If trace elements remain in the wastewater, the movement of the drive cylinder 438 and rotating roller 4310 adds chemicals from the storage tank 435 to the wastewater for a small-scale, secondary chemical addition. Conversely, once the trace elements are removed, the stored chemicals can be used in the next wastewater treatment. During chemical addition, the drive motor 51 activates, causing the double gear 53 to rotate in conjunction with the first drive chain 55. The moving double gear 53, in conjunction with the second drive chain 56, causes the driven gear 54 to move. The driven gear 54 then drives the drive wheel 58 located on the same drive roller, causing the movable base 2 to move above the water storage tank 1, thus completing the chemical addition process. During the chemical addition, the pulverizing motor 341 starts working, breaking up suspended solids. The pressure roller 344 then lowers these solids below the water surface, allowing some to settle. The collecting motor 347 then starts working, driving the first bevel gear 348 to rotate. This first bevel gear 348 then drives the second bevel gear 349, which in turn drives the belt conveyor 3410 to collect the remaining suspended solids. The pressure roller 344 ensures that the suspended solids remain below the water surface during granular chemical addition, preventing the chemical from being on top of them and ensuring smooth chemical addition.

5. A method of operating the wastewater treatment device according to claim 4, characterized in that, Includes the following steps: S1: When wastewater treatment is required, the wastewater is first transferred to a storage tank, then raw materials are added to the granule feeding unit or solution feeding unit, and then the appropriate reagents are selected according to the actual situation. S2: When granular agents are selected for dispensing, different agents are placed in the holding tank according to the requirements. The agents can then enter the dispensing device through the discharge port. The dispensing motor starts working, and the moving dispensing motor drives the dispensing shaft to rotate. The moving dispensing shaft drives the dispensing gear to rotate, and the agents fall into the teeth of the dispensing gear. With the cooperation of the dispensing gear, the granular agents can be transferred to the discharge pipe. Then, under its own gravity, the agents can fall into the wastewater, completing the agent addition work. S3: When liquid agent is selected for dispensing, the agent is added to the agent storage tank. Then, the water pump installed in the agent storage tank allows the agent to enter the connection end. The agent can then pass through the isolated injection section, while the remaining injection section is closed. The liquid solution can then pass through the injection section and the transport pipe, and then be sprayed out from the free end of the outlet pipe. S4: While performing step S3, the flipping cylinder starts working, which in turn drives the flipping block to move. The moving flipping block then drives the adjusting shaft to move, which in turn drives the limit seat to move, thereby adjusting the position of the measuring cylinder. Then the measuring cylinder starts working, which positions the outlet of the connecting pipe above the measuring cylinder, allowing the addition of reagent to the measuring cylinder. This causes a change in the pressure detector value. After a predetermined time, the telescopic cylinder starts working, which in turn drives the rotating roller to work. The rotating roller blocks the outlet of the connecting end, preventing the reagent from entering the measuring cylinder. At this time, the pressure detector value replaces the reagent addition efficiency, allowing the injection efficiency of the remaining injection section to be determined. The reagent in the inner cylinder flows to the reagent storage tank through the drain pipe. S5: Then the telescopic cylinder in the remaining injection section starts to work, which allows it to be in the open state, and the agent can flow out from the outlet pipe. Since the trace element content in the wastewater has been tested before treatment, the amount of agent to be added can be calculated. When the predetermined addition value is reached, the water pump stops working, and the agent addition work is completed. During the water pump shutdown process, due to inertia, it may continue to operate for a certain period of time, continuing to deliver chemicals. At this time, the telescopic cylinder starts working, driving the rotating roller to move. Then, the drive cylinder starts working, which in turn drives the drive seat to work. The moving drive seat then drives the sealing gasket to move away from the connecting seat, allowing excess chemicals to be stored in this location. When trace elements are still present in the wastewater, the movement of the drive cylinder and rotating roller allows chemicals from the storage tank to be added back into the wastewater for a small-scale secondary chemical addition. Conversely, once the trace elements in the wastewater are completely removed, the stored chemicals can be used in the next wastewater treatment. S6: During the process of adding the medicine, the drive motor starts to work, and the moving drive motor can make the double gear start to rotate with the cooperation of the first drive chain. The moving double gear can make the driven gear start to move with the cooperation of the second drive chain. The moving driven gear can drive the drive wheel located on the same drive roller to start to move, thereby enabling the movable base to move above the water storage tank, thus completing the medicine moving and adding work. S7: During the process of adding the agent, the crushing motor starts to work, and the moving crushing motor can crush the suspended matter. Then, under the action of the pressure roller, it is brought below the water surface, so that some of the suspended matter can sink to the bottom. Then the collecting motor starts to work, and the moving collecting motor can drive the first bevel gear to rotate. The moving first bevel gear can drive the second bevel gear to move, which can drive the belt conveyor to move, thus completing the collection of the remaining suspended matter.
