Technical Field

[0001] The utility model relates to a filtering device, in particular to a dust recovery device and a dust recovery system. Background Art

[0002] In a production workshop, since dust is not recovered during processes such as feeding, the air environment in the production workshop is poor, seriously affecting the health of workers. Currently, some production workshops are equipped with an air purification system, which circulates and filters the air in the workshop to improve air quality. However, the efficiency of this air dust removal and filtration is low, and the filter needs to be replaced frequently, resulting in high usage costs. Therefore, there is an urgent need for a more reliable dust recovery device. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a dust recovery device and a dust recovery system to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A dust recovery device includes: a recovery tank, an air inlet pipe is arranged at the bottom side thereof; an antifoaming assembly, which is connected inside the recovery tank, the antifoaming assembly is provided with a plurality of through holes penetrating in the up and down directions, and a plurality of downwardly directed bubble-piercing tips are arranged at the bottom side of the antifoaming assembly; a negative pressure pump, which is connected to the recovery tank, the negative pressure pump is connected with an exhaust pipe, and the negative pressure pump is used to make the inside of the recovery tank form a negative pressure; a spraying mechanism, which includes a spray head connected inside the recovery tank, and the spray head is located above the antifoaming assembly.

[0006] This technical solution has at least the following beneficial effects: During use, the air inlet pipe can be connected to an external feeding device, and the negative pressure pump can directly suck the dust generated by the feeding device during feeding from the air inlet pipe into the recovery tank. A solvent can be added to the recovery tank. The airflow with dust enters the solvent and rises. During the rising process, the dust particles in the airflow are dissolved by the solvent. Some undissolved dust particles rise with the airflow and form bubbles. When passing through the antifoaming assembly, they are pierced by the bubble-piercing tips and then fall back into the solvent to be dissolved again. The spraying mechanism sprays the solvent inside the recovery tank, which can increase the humidity inside the recovery tank, causing the undissolved dust particles to condense and fall. The solvent sprayed by the spraying mechanism can also directly wash the dust downward. The gas after dissolution and filtration is discharged outward through the exhaust pipe. After long-term use, only the solvent needs to be replaced. In this way, the dust recovery device can be directly used at the feeding place, effectively reducing the amount of dust in the workshop, and improving the filtration effect on the airflow through the dissolution and recovery of dust, reducing the usage and maintenance costs, and being better promoted and applied.

[0007] As a further improvement of the above technical solution, a shunt pipe is connected inside the recovery tank, and a plurality of capillary tubes are connected to the shunt pipe. A plurality of exhaust holes are respectively arranged on the plurality of capillary tubes, and the shunt pipe is connected to the intake pipe. The air flow sent in from the intake pipe is shunted to a plurality of capillary tubes through the shunt pipe. The inner diameter of the capillary tubes is small, which increases the speed when the air flow is discharged. In this way, there are multiple air outlet points in the solvent, and the air flow has a longer flow path in the solvent, effectively improving the dissolution effect on dust.

[0008] As a further improvement of the above technical solution, a rotary drive member is connected to the top side of the recovery tank, and the rotary drive member is drivingly connected with a stirring paddle, and the stirring paddle is located inside the recovery tank. When recovering and filtering dust, the rotary drive member drives the stirring paddle to rotate inside the recovery tank, which can reduce the problems of caking on the inner wall of the recovery tank and material accumulation, and improve the uniformity of the mixing of dust and solvent, making the solution in the recovery tank more uniform for re-recovery and utilization.

[0009] As a further improvement of the above technical solution, the defoaming assembly includes a partition net connected inside the recovery tank and a plurality of spikes connected to the bottom side of the partition net. A plurality of communication holes are formed in the partition net, and the bottom ends of the plurality of spikes respectively form the bubble-piercing tips. A partition net is connected to the inner side wall of the recovery tank, and the communication holes for the air flow to rise and pass through are formed by the structure of the partition net itself, and a plurality of spikes are connected to the bottom side of the partition net for piercing bubbles.

[0010] As a further improvement of the above technical solution, the spraying mechanism includes a circulation pump, an input pipe and an output pipe. The two ends of the input pipe are respectively connected between the input end of the circulation pump and the bottom side of the recovery tank, and the two ends of the output pipe are respectively connected between the output end of the circulation pump and the top of the recovery tank. A plurality of spray heads are respectively connected to the output pipe. When in use, the circulation pump can pump the solvent in the recovery tank to the spray heads through the input pipe and the output pipe, so that the solvent can be recycled by spraying, improving the utilization rate of the solvent.

[0011] As a further improvement of the above technical solution, a discharge pipe is connected to the bottom side of the recovery tank, and a switching valve is arranged on the discharge pipe. When dust needs to be recovered, the switching valve on the discharge pipe can be closed. After a long time of dust recovery treatment, the switching valve on the discharge pipe can be opened to discharge the solution in the recovery pipe through the discharge pipe, so as to improve the convenience of dust recovery.

[0012] As a further improvement of the above technical solution, a filter is provided at the connection between the negative pressure pump and the exhaust pipe. When the negative pressure pump discharges the gas in the recovery tank to the outside through the exhaust pipe, the filter can be used to filter the gas again, so as to further improve the cleanliness of the gas. Since the gas has been dissolved and recovered by the solvent, the service life of the filter can be effectively increased.

[0013] A dust recovery system includes a feeding device and the above-mentioned dust recovery device. A dust chamber is provided in the feeding device. A conveying fan is connected to the feeding device. The conveying fan is connected to a conveying pipe, and the intake pipe communicates with the conveying pipe.

[0014] The technical solution has at least the following beneficial effects: The feeding device can perform manual or automatic feeding.

Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflicting with each other.

[0022] Referring to Figure 1 , a dust recovery device, comprising: a recovery tank 1, an intake pipe 11 is arranged at the bottom side thereof; a defoaming component 2, which is connected inside the recovery tank 1, a plurality of through holes penetrating in the up and down direction are arranged on the defoaming component 2, and a plurality of downward bubble-piercing tips 21 are arranged at the bottom side of the defoaming component 2; a negative pressure pump 3, which is connected to the recovery tank 1, the negative pressure pump 3 is connected with an exhaust pipe 31, and the negative pressure pump 3 is used to make the inside of the recovery tank 1 form a negative pressure; a spraying mechanism, which includes a spray head 41 connected inside the recovery tank 1, and the spray head 41 is located above the defoaming component 2.

[0023] In this dust recovery device, when in use, the air inlet pipe 11 can be connected to an external feeding device. By using the negative pressure pump 3, the dust generated by the feeding device during feeding can be directly sucked from the air inlet pipe 11 into the recovery tank 1. A solvent can be added into the recovery tank 1. The air flow with dust enters the solvent and rises. During the rising process, the dust particles in the air flow are dissolved by the solvent. Some undissolved dust particles rise with the air flow and form bubbles. When passing through the defoaming assembly 2, they are pierced by the bubble-piercing tips 21 and then fall back into the solvent to be dissolved. The spraying mechanism sprays the solvent in the recovery tank 1, which can increase the humidity in the recovery tank 1, causing the undissolved dust particles to condense and fall. The solvent sprayed by the spraying mechanism can also directly wash the dust downward. The filtered gas is discharged outward from the exhaust pipe 31. After long-term use, only the solvent needs to be replaced. In this way, the dust recovery device can be directly used at the feeding point, effectively reducing the amount of dust in the workshop. And through the dissolution and recovery of dust, the filtering effect on the air flow is improved, and the use and maintenance costs are reduced, which can be better promoted and applied.

[0024] The air flow with dust can be directly input from the air inlet pipe 11 into the recovery tank 1. When there is only one air inlet in the recovery tank 1, there is likely to be a problem that the solvent cannot fully dissolve the dust. Therefore, in this embodiment, a shunt pipe is connected in the recovery tank 1. A plurality of capillary tubes 12 are connected to the shunt pipe. A plurality of exhaust holes are respectively arranged on the plurality of capillary tubes 12. The shunt pipe is connected to the air inlet pipe 11. The air flow sent from the air inlet pipe 11 is shunted to a plurality of capillary tubes 12 through the shunt pipe. The inner diameter of the capillary tubes 12 is small, which increases the speed of the air flow when discharged. In this way, there are multiple air outlet points in the solvent, and the air flow has a longer flow path in the solvent, effectively improving the dissolution effect on the dust.

[0025] In order to improve the fluidity of the solvent in the recovery tank 1, in this embodiment, a rotary drive member 51 is connected to the top side of the recovery tank 1. The rotary drive member 51 can be a reduction motor. The rotary drive member 51 is drivingly connected to a stirring paddle 52. The stirring paddle 52 is located in the recovery tank 1. When recovering and filtering the dust, the rotary drive member 51 drives the stirring paddle 52 to rotate in the recovery tank 1, which can reduce the problems of caking on the inner wall of the recovery tank 1 and material accumulation, and improve the uniformity of the mixing of the dust and the solvent, making the solution in the recovery tank 1 more uniform for recycling.

[0026] The defoaming component 2 can be a grid connected inside the recovery tank 1, and communication holes are formed by using the gaps between the grids. In this embodiment, the defoaming component 2 includes a partition net connected inside the recovery tank 1 and a plurality of spikes connected to the bottom side of the partition net. A plurality of the communication holes are formed in the partition net, and the bottom ends of the plurality of spikes respectively form the bubble-piercing tips 21. The partition net is connected to the inner side wall of the recovery tank 1, and communication holes for the air flow to rise through are formed by using the structure of the partition net itself, and a plurality of spikes are connected to the bottom side of the partition net for piercing the bubbles.

[0027] When it is necessary to spray the solvent into the recovery tank 1, a new solvent can be directly input for spraying. A pipeline for discharging and recovering the solvent needs to be arranged at the bottom side of the recovery tank 1 to ensure that the solution volume in the recovery tank 1 is at a normal level. In order to improve the utilization rate of the solvent, in this embodiment, the spraying mechanism includes a circulation pump 42, an input pipe 43 and an output pipe 44. The two ends of the input pipe 43 are respectively connected between the input end of the circulation pump 42 and the bottom side of the recovery tank 1, the two ends of the output pipe 44 are respectively connected between the output end of the circulation pump 42 and the top of the recovery tank 1, and a plurality of the spray heads 41 are respectively connected to the output pipe 44. During use, the circulation pump 42 can pump the solvent in the recovery tank 1 to the spray heads 41 through the input pipe 43 and the output pipe 44, so that the solvent can be recycled by spraying, and the utilization rate of the solvent can be improved.

[0028] In some embodiments, a discharge pipe 13 is connected to the bottom side of the recovery tank 1, and a switching valve is arranged on the discharge pipe 13. When it is necessary to recover the dust, the switching valve on the discharge pipe 13 can be closed. After a long time of dust recovery treatment, the switching valve on the discharge pipe 13 can be opened, and the solution in the recovery pipe can be discharged through the discharge pipe 13, so that the convenience of dust recovery can be improved.

[0029] In some embodiments, a filter is arranged at the connection between the negative pressure pump 3 and the exhaust pipe 31. The filter is a structure for filtering and adsorbing gases, and can be a primary filter plate, a medium-effect filter plate, etc. When the gas in the recovery tank 1 is discharged outward from the negative pressure pump 3 through the exhaust pipe 31, the filter can be used to filter the gas again, so that the cleanliness of the gas can be further improved. Since the gas has been dissolved and recovered by the solvent, the service life of the filter can be effectively improved.

A conveying fan 61 is connected to the feeding device 6. The conveying fan 61 is connected to a conveying pipe, and the intake pipe 11 communicates with the conveying pipe.

[0031] In this dust recovery system, the feeding device 6 can be an automatic feeding machine or a manual feeding machine, enabling manual or automatic feeding. When feeding, a large amount of dust is generated into the dust chamber. At this time, the dust is conveyed from the conveying pipe to the intake pipe 11 through the conveying fan 61. In this way, the dust generated by the feeding device 6 can be directly collected by the dust recovery device, effectively reducing the amount of dust in the workshop. Moreover, through the dissolution and recovery of the dust, the air flow filtration effect is improved, and the use and maintenance costs are reduced, making it more suitable for popularization and application.

[0032] Multiple dust recovery devices can be connected to the feeding device 6 in different forms. In the first embodiment, multiple dust recovery devices are connected to the feeding device 6 in parallel. Specifically, the number of the dust recovery devices is multiple, and multiple intake pipes 11 are respectively connected to the conveying pipe.

[0033] In the second embodiment, multiple dust recovery devices are connected to the feeding device 6 in series. Specifically, multiple dust recovery devices are arranged in series. The conveying pipe is connected to the intake pipe 11 of the recovery device at the frontmost stage. Among two adjacent stages of the dust recovery devices, the exhaust pipe 31 of the recovery device at the previous stage is connected to the intake pipe 11 of the recovery device at the next stage. The dust generated by the feeding device 6 can be sent to each dust recovery device step by step. By respectively purifying the gas through multiple dust recovery devices, the gas purification effect can be greatly improved.
