Description

Technical Field

[0001] The invention relates to the technical field of building air system cleaning, and in particular to a cleaning capsule recovery device. Background Art

[0002] Air ducts in building air conditioning systems are prone to dust accumulation and the breeding of bacteria. Consequently, the General Administration of Quality Supervision, Inspection and Quarantine of China has issued the national standard "Specifications for Cleaning Air Conditioning and Ventilation Systems (GB1920-2003)", the Ministry of Health has published the "Hygiene Specifications for Centralized Air Conditioning and Ventilation Systems in Public Places", and the Ministry of Construction has formulated the "Specifications for Operation and Management of Air Conditioning and Ventilation Systems" to strengthen the cleaning of central air conditioning ducts. Traditionally, air duct cleaning involves lifting dust into the air and then using a vacuum to remove it. However, this method suffers from incomplete cleaning, complex construction, and a lengthy process. Therefore, a new cleaning method has emerged that uses gas-powered cleaning capsules to propel dust out of the ducts.

[0003] In actual use, it was found that although the cleaning capsules pushed by gas to move in the air duct are effective in removing dust, due to the friction of the duct wall itself and the increased resistance at the bends of the duct, the cleaning capsules may not move smoothly in the duct and may even stay in the duct, increasing the difficulty of implementation. Summary of the Invention

[0004] The present invention aims to provide a cleaning capsule recovery device to solve the problem that the cleaning capsule does not move smoothly in the air system duct when the cleaning capsule is used to push dust to clean the air system duct.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a cleaning capsule recovery device, comprising a box body, an air pump, a recovery bag and a dust separation mechanism, a storage box is rotatably provided in the box body, the box body is connected to a recovery pipe, and the recovery pipe is connected to the inside of the storage box; the dust separation mechanism comprises a dust separation box and a spiral tube, the dust separation box and the recovery bag are both connected to the bottom of the storage box, and the dust separation box is located directly below the recovery pipe; the spiral tube is arranged in the dust separation box, both ends of the spiral tube are connected to a funnel part, the air pump is connected to the dust separation box, and a filter is provided between the air pump and the dust separation box.

[0006] The beneficial effects of this solution are: after connecting the device to the outlet end of the air duct through the recovery pipe, starting the vacuum pump to extract air will generate negative pressure suction at the front end of the cleaning capsule, thereby helping the cleaning capsule to move more smoothly in the air duct, solving the problem of the cleaning capsule not moving smoothly in the air duct when using the cleaning capsule to push dust to clean the air duct, and realizing the recovery of the cleaning capsule. In addition:

[0007] 1. When the cleaning capsule enters the storage box through the recovery pipe, the dust pushed in the cleaning capsule dust collecting groove falls into the spiral pipe under the action of negative pressure suction and gravity.

The enlarged opening of the lower funnel part reduces the pressure of the dust-containing gas and the flow speed, and further enables the dust to stay more in the bottom of the dust separation box due to gravity, reduces the possibility of dust entering the air extractor, and reduces the situation of a large amount of dust flying in the dust separation box.

[0029] Example 1

[0030] Example 1 is basically as shown in the attached Figures 1-7 As shown, Figure 1 The cleaning capsule recovery device shown includes a housing 1, an air extractor 2, a dust separation mechanism, and a recovery bag 8. The housing 1 is a hollow cylinder, with a similarly hollow cylindrical storage box 4 rotatably connected to it. Four support legs 12 are fixed to the bottom of the housing 1, and a recovery pipe 11 is welded to the top of the housing 1. This pipe 11 communicates with the interior of the storage box 4, and the other end of the pipe 11 can be sealed with the outlet of the building's air duct via a flange. When using the cleaning capsule 9 to clean dust from the building air system pipe, the cleaning capsule 9 is pushed into the air duct from the inlet end through the cleaning capsule 9 gas push device, and the cleaning capsule 9 is pushed to move toward the outlet end in the air duct by high-pressure gas, thereby pushing out the dust accumulated in the air duct; after the recovery and cleaning device is connected to the outlet end of the air duct through the recovery pipe 11, the vacuum pump 2 is started to extract air, so that the front end of the cleaning capsule 9 can generate negative pressure suction, which helps the cleaning capsule 9 to move more smoothly in the air duct, prevents the cleaning capsule 9 from staying in the air duct, and realizes the recovery of the cleaning capsule 9. Figure 2 As shown, the longitudinal cross-section of the cleaning capsule 9 in this embodiment is a square with rounded corners, and a concave dust collecting groove 91 is provided at the front end of the cleaning capsule 9 in the forward direction; correspondingly, the recovery tube 11 is also a square tube with rounded corners, and the cleaning capsule 9 can contact the inner wall of the recovery tube 11 to ensure that the negative pressure suction generated by the vacuum pump 2 on the front end of the cleaning capsule 9 can effectively act on the cleaning capsule 9.

[0031] In this embodiment, the storage box 4 is provided with four storage compartments 41. Figure 4As shown, the top and bottom of the storage compartment 41 are hollowed out, the top of the storage box 4 is in contact with the top of the box body 1, and the width and height of the interior of the storage compartment 41 are slightly larger than the width and height of the cleaning capsule 9; a connecting hole and four weight-reducing holes 401 distributed around the connecting hole are provided at the center of the storage box 4, and the weight-reducing holes 401 can reduce the weight of the storage box; in addition, the weight-reducing holes 401 make the weight of the outer ring of the storage box 4 greater than the weight of its inner ring, so that the four storage compartments 41 located at the outer ring will be more stable during the rotation of the storage box 4, thereby reducing the shaking of the storage box 4 during rotation, making the top and bottom of the storage compartment 41 in contact with the inner wall of the box body 1, ensuring a negative pressure environment in the storage compartment 41, thereby ensuring the suction effect on the front end of the cleaning capsule 9. Figure 3 As shown, the bottom of the storage box 4 is provided with a groove wheel mechanism to realize rotation. The groove wheel mechanism includes a dial 43 and a groove wheel. The dial 43 and the wheel groove 42 are both rotatably connected to the bottom of the box body 1. The rotation connection method takes the wheel groove 42 as an example: a plurality of T-shaped connecting blocks are fixed on the top surface of the wheel groove 42, and the plurality of T-shaped connecting blocks are evenly distributed on the same circumference. An annular groove with a T-shaped cross-section is opened on the bottom surface of the box body 1, and the tops of the T-shaped connecting blocks are all slidably connected to the annular groove. Four sliding slots 521 are provided on the wheel groove 42, and a connecting column is vertically fixed to the top surface of the center of the wheel groove 42, which passes through the box body 1 and is fixed in the connecting hole in the center of the storage box 4; a pull rod is welded and fixed on the dial 43, and the dial 43 is connected to the first motor 431, and the first motor 431 is fixed to the bottom of the box body 1 through a support plate. The motor drives the dial 43 to rotate, thereby driving the lever to rotate 360° with the dial 43 as the center. During the rotation, the lever enters the four sliding slots 521 of the wheel groove 42 and then drives the wheel groove 42 to rotate, and the dial 43 rotates one circle, driving the wheel groove 42 to rotate a quarter circle, and the rotation of the wheel groove 42 drives the storage box 4 to rotate a quarter circle in the box body 1.

[0032] like Figure 2As shown, the dust separation mechanism includes a dust separation box 3 fixed to the bottom of the box body 1 and communicated with one of the storage compartments 41 in the storage box 4, and a spiral pipe 33. The dust separation box 3 is located directly below the recovery pipe 11. The outer wall of the spiral pipe 33 is welded to the inner wall of the dust separation box 3, and the upper and lower ends of the spiral pipe 33 are integrally formed with funnel portions 34. The spiral pipe 33 is connected with the smaller end of the funnel portion 34, the larger end of the upper funnel portion 34 is the same size as the storage compartment and is fixed with a steel mesh to prevent the cleaning capsule from being stuck in the funnel portion, and the outer side wall around the upper funnel portion 34 is sealingly welded to the inner wall of the dust separation box 3 to further improve the stability of the spiral pipe 33 after connection. The air extractor 2 is fixed on the side wall of the dust separation box 3 by screws, and the air extraction pipe of the air extractor 2 is communicated with the inside of the dust separation box 3 after being fixed. When the air extractor 2 is started, the air in the dust separation box 3, the spiral pipe 33, the storage compartment 41, the recovery pipe 11 and the front end of the cleaning capsule 9 in the air pipe is extracted outward through the air extraction pipe. A filter screen is fixed between the air extraction pipe and the dust separation box 3. In this embodiment, two filter screens are arranged at intervals, which are a first filter screen 38 close to the dust separation box 3 and a second filter screen 39 close to the air extractor 2, to improve the filtering effect and prevent dust from entering the air extractor 2. When the cleaning capsule 9 enters the storage compartment 41 of the storage box through the recovery pipe 11, most of the dust pushed in the dust collection groove 91 falls into the spiral pipe 33 through the upper funnel portion 34 under the action of air flow and gravity, and falls in the spiral pipe 33.

[0033] In addition, the inner diameter of the spiral pipe 33 gradually increases from top to bottom. When the air extractor 2 is working, the air in the air pipe is extracted through the recovery pipe 11 and the spiral pipe 33, so that the inside of the spiral pipe 33 continuously forms a downward blowing wind. Due to the small inner diameter of the upper end of the spiral pipe 33 and the gradually increasing inner diameter of the lower end, the wind speed in the spiral pipe 33 gradually decreases from top to bottom under the same air source, so that the speed of the dust falling in the spiral pipe 33 gradually decreases. Combined with the expansion of the lower funnel portion 34, the gas containing dust is released and the flow speed is reduced, so that the dust is more easily deposited at the bottom of the dust separation box 3 due to the double action of speed reduction and gravity. At the same time, in order to ensure the negative pressure effect on the front end of the cleaning capsule 9, the size of the pipe diameter of the spiral pipe 33 can be adjusted in detail.

[0034] As Figure 5As shown, the dust collection box 32 is detachably connected to the bottom of the dust separation box 3. Specifically, protrusions 31 are integrally formed on the left and right ends of the bottom of the dust separation box 3, and clamping portions 321 are fixed to the left and right ends of the top of the dust collection box 32. The inner sides of the clamping portions 321 are each provided with a clamping groove, and the protrusions 31 are slidably connected to the clamping groove. In this embodiment, the protrusions 31, the clamping portions 321, and the clamping groove are all trapezoidal. During installation, the smallest end of the trapezoidal protrusion 31 first enters the largest end of the clamping groove. While facilitating the sliding installation of the dust collection box 32 into the bottom of the dust separation box 3, the gradually increasing protrusion 31 fits into the clamping groove, which can more tightly enhance the sealing effect of the connection. In addition, the protrusion 31 and the clamping groove are detachably connected, so that when air inside the dust collection box 32 overflows, it needs to pass through multiple horizontal and vertical gaps to reach the outside, thereby further improving the sealing of the connection. Most of the dust pushed out by the cleaning capsule dust collecting groove 91 directly enters the dust collecting box 32 through the spiral tube 33, reducing the large amount of dust in the dust separation box 3.

[0035] like Figure 2 、 Figure 3 As shown, a vertical rod is vertically fixed to the bottom of the wheel groove 42, and a first bevel gear is fixed to the bottom of the vertical rod. A cleaning assembly is also included, which includes a second bevel gear 36, a connecting rod 35, and a scraper 37. The connecting rod 35 is sealed and rotatably connected to the side wall of the dust separation box 3 facing the first filter 38. The end of the connecting rod 35 near the first filter 38 is fixed to the scraper 37. After fixing, the scraper 37 is in contact with the first filter 38, and the length of the scraper 37 is equal to the diameter of the first filter 38. The second bevel gear 36 is fixed to the other end of the connecting rod 35. After fixing, the second bevel gear 36 meshes with the first bevel gear. The number of teeth on the first bevel gear is four times that of the second bevel gear 36. When the first bevel gear rotates a quarter of a turn, the second bevel gear 36 rotates one turn. When the second bevel gear 36 rotates one circle, the scraper 37 is driven to rotate one circle through the connecting rod 35. The rotation of the scraper 37 cleans the dust attached to the first filter 38, further reducing the possibility of dust entering the exhaust fan 2.

[0036] In this embodiment, the wheel groove 42 mechanism drives the storage box 4 to rotate counterclockwise, with the recovery pipe 11 as the starting point. For the convenience of explanation, the storage compartment 41 connected to the recovery pipe 11 at this time is defined as the first storage compartment 41. When the dial 43 rotates one circle and drives the storage box 4 to rotate 90 degrees counterclockwise, as shown in FIG. Figure 1As shown, after dust separation by the dust separation mechanism, the cleaning capsule 9 enters the next mechanism, which is the vibration mechanism. Furthermore, as the cleaning capsule 9 enters the vibration mechanism, the blocking effect of the funnel portion 34 above the spiral tube 33 and the rotating storage box 4 within the housing 1 automatically separate the dust from the cleaning capsule 9 and the cleaning capsule 9 from the negative pressure environment, thereby enabling the automatic recovery of the cleaning capsule 9.

[0037] The vibration mechanism includes a connecting seat 5, a crank 51, an inverted T-shaped sliding member and a sliding rod 53. Figure 1 As shown, the connecting seat 5 is welded and fixed to the outer wall of the box body 1, and the crank 51 is rotatably connected to the connecting seat 5. The crank 51 is connected to a driving member. In this embodiment, the driving member is a second motor. The second motor is installed inside the connecting seat 5. The output shaft of the second motor extends out of the connecting seat 5 and is fixed to one end of the crank 51. A limit block is fixed to the other end of the crank 51. Figure 6 As shown, a pair of parallel slide bars 53 are bent into a C-shape at both ends. A vibration plate 54 is welded to the top of the two slide bars 53, and another vibration plate 54 is welded to the bottom of the two slide bars 53. The bottom of the inverted T-shaped slide is a horizontal portion with a horizontal through slot 521 formed in the horizontal portion. The other end of the crank 51 is slidably connected to the through slot 521 via a limit block. The middle of the inverted T-shaped slide is a vertical portion with a fixed block 522 fixed to the top of the vertical portion. The two slide bars 53 are respectively fixed to the ends of the fixed block 522. At the same time, two vertical sliding holes are formed at both ends of the connecting base 5, and the two slide bars 53 are slidably connected to the sliding holes at both ends. Vibration holes 13 are provided at the top and bottom of the housing 1, coaxially with the connecting base 5. Both vibration holes 13 are connected to the storage compartment 41. The upper and lower vibration plates 54 enter the storage compartment 41 through the upper and lower vibration holes 13, respectively. When the second motor starts and drives the crank 51 to rotate 360° around the second motor, the inverted T-shaped sliding member drives the two slide rods 53 to reciprocate up and down, thereby driving the two vibration plates 54 to vibrate and beat the cleaning capsules 9 that rotate into the cleaning capsules, further shaking off the dust adhering to the cleaning capsules 9. In addition, the lower vibration plate 54 has several leakage holes, and a dust box is fixed below the lower vibration hole 13. The shaken dust is collected in the dust box through the vibration plate 54. At the same time, two springs 55 are fixed between the fixed block 522 and the connecting seat 5, and the two springs 55 are respectively sleeved on the two sliding rods 53. The springs 55 will be squeezed and stretched when the sliding rod 53 moves up and down, thereby generating elastic force on the sliding rod 53, helping the sliding rod 53 to drive the vibration plate 54 to smoothly beat the cleaning capsule 9 to remove dust.

[0038] Then the wheel groove 42 mechanism drives the storage box 4 to continue to rotate 90 degrees counterclockwise, so that the cleaning capsule 9 after vibration dust removal enters the next mechanism, which is the flushing mechanism.Figure 7 As shown, the flushing mechanism includes a nozzle 6, a water inlet pipe 61, and a water outlet pipe 62. There are multiple nozzles 6, and all nozzles 6 are tilted. Specifically, the tilted arrangement is as follows: a flushing box 63 is fixed at the bottom of the box body 1. The flushing box 63 is in an inverted trapezoidal shape and communicates with the first storage compartment 41. Multiple nozzles 6 are evenly fixed on one side wall of the inverted trapezoidal flushing box 63, so that the spray holes of the nozzles 6 are tilted upward after being fixed. The water inlet pipe 61 is connected to all nozzles 6, and the water outlet pipe 62 is connected to the bottom of the flushing box 63 to discharge the dirty water after flushing. The dust collecting trough 91 makes the front end of the cleaning capsule 9 concave, and the unilaterally inclined nozzle 6 on the flushing box 63 flushes water toward the inner wall of the dust collecting trough 91. In this embodiment, water is sprayed upward from the lower right corner of the dust collecting trough 91 to directly flush the left side of the dust collecting trough 91. After flushing, the water is splashed back to the right side of the dust collecting trough 91 and then flushed. That is, the right side is the secondary use of clean water, thereby achieving comprehensive flushing of the dust collecting trough 91 while reducing water usage, saving energy and protecting the environment, and reducing flushing costs.

[0039] Finally, the wheel groove 42 mechanism drives the storage box 4 to rotate 90 degrees counterclockwise, so that the rinsed cleaning capsule 9 enters the last blowing mechanism. Figure 5 As shown, the blowing mechanism includes a blower 7, which is fixed to the top of the box body 1 by screws. The blowing port of the blower 7 is downwardly connected to the first storage compartment 41. The recovery bag 8 is clamped to the bottom of the box body 1 and is located directly below the blower 7. When the blower 7 is activated, the cleaning capsule 9 is blown downward, so that the cleaning capsule 9 falls smoothly into the recovery bag 8.

[0040] The device also includes an automatic control system, which includes a single-chip microcomputer, an electric valve installed on the water inlet pipe 61, and a sensor fixed above the funnel portion 34. The sensor, the air extractor 2, the air blower 7, the first motor 431, the second motor, and the electric valve are all connected to the single-chip microcomputer. When using this device to recover and clean the cleaning capsule 9, the recovery pipe 11 is first sealed to the outlet end of the air duct. Then, the device is started and the air extractor 2 begins to operate. The air in front of the cleaning capsule 9 in the air duct is sucked through the dust separation box 3, the first storage compartment 41, and the recovery pipe 11, creating a suction force at the front of the cleaning capsule 9, which helps the cleaning capsule 9 move smoothly. Then, the cleaning capsule 9 enters the first storage compartment 41 through the recovery pipe 11. At this time, the first storage compartment 41 is connected to the dust separation box 3. All the dust pushed in the dust collecting trough 91 enters the spiral tube 33 through the funnel part 34 and spirally falls in the spiral tube 33. The dust is gradually absorbed due to the downward movement potential energy. Moreover, since the inner diameter of the spiral tube 33 gradually increases from top to bottom, the wind speed inside the spiral tube 33 gradually decreases from top to bottom, further slowing down the speed at which the dust falls in the spiral tube 33. Combined with the enlarged mouth of the funnel part 34 below, the dust-containing gas is depressurized and the flow speed is reduced, so that the dust is more deposited in the dust collection box 32 at the bottom of the dust separation box due to the dual effects of deceleration and gravity, reducing the flying of dust in the device; and sending the dust into the dust collection box 32 with the help of the spiral tube 33 can also reduce the possibility of dust entering the exhaust fan 2, and at the same time reduce the occurrence of a large amount of dust in the dust separation box 3. A small portion of dust that enters the dust collecting box 32 enters the dust separation box 3 under the action of the air exhauster 2 , but will be filtered by the first filter 38 and the second filter 39 and will not enter the air exhauster 2 .

[0041] When the cleaning capsule 9 is sensed to have fallen into the first storage compartment 41 and remained there for a certain period of time, the single-chip microcomputer controls the first motor 431 to rotate counterclockwise 90°, causing the first storage compartment 41 to rotate 90° counterclockwise and enter the vibration mechanism. The second motor then activates to rotate the crank 51, which, through the slide bar 53, drives the upper and lower vibration plates 54 to move back and forth, further shaking the cleaning capsule 9 and removing dust. After the second motor rotates for a certain period of time, the second motor returns the crank 51 to its original position, causing the first storage compartment 41 to rotate counterclockwise again 90° with the cleaning capsule 9 and enter the flushing mechanism. The single-chip microcomputer controls the electric valve to activate, and water is sprayed obliquely through the water inlet pipe 61 through the nozzle 6 into the dust collection trough 91, thoroughly flushing the trough wall. When the flushing time reaches the set value, the electric valve closes, and the first storage compartment 41 again drives the flushed cleaning capsule 9 to rotate to the blowing mechanism. Finally, the single-chip microcomputer controls the blower 7 to start, blowing the cleaning capsule 9 into the recovery bag 8 below, completing the cleaning and recovery of the cleaning capsule 9.

[0042] Example 2

[0043] Example 2 is as follows Figure 8 The cleaning capsule recovery device shown is different from that of Example 1 in that: a second annular dust collecting groove is provided on the side wall of the cleaning capsule 9, and a vibration plate 54 is welded and fixed to the top of the two slide rods 53, and anti-slip blocks 531 are welded and fixed to the bottom ends of the two slide rods 53 respectively, and a plurality of leakage holes are provided at the bottom of the box body 1, all of which are located below the vibration plate 54.

[0044] The specific structure of the cleaning capsule 9 with an annular second dust collecting groove on the side wall is fully disclosed in the patent of a pipe cleaning capsule 9 for an air conditioning system with publication number: CN217314961U, and will not be repeated in this embodiment. The cleaning capsule 9 is made of a lightweight elastic material, and the material of the cleaning capsule 9 is an easily compressible material. Therefore, the vibration mechanism is changed to a method of vibrating, beating and shaking the dust of the cleaning capsule 9, and the vibration plate 54 at the top is used to beat downward. During the beating process, the bottom of the cleaning capsule 9 is fixed to the bottom of the box 1. Therefore, during the continuous beating of the vibration plate 54 at the top, the cleaning capsule 9 made of elastic material is squeezed and vibrated, so that the dust collected in the second dust collecting groove on the side wall is shaken off, thereby achieving the purpose of cleaning the dust in the annular second dust collecting groove. The dust beaten, squeezed and shaken off falls into the dust receiving box 56 through the leakage hole at the bottom of the box 1.

[0045] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
