Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical equipment, in particular to a glass processing equipment, more particularly to a glass cleaning device. BACKGROUND

[0002] In the process of glass manufacturing, large-size glass usually has dirt on its surface after production. In order to ensure that the surface of the large-size glass is clean and free of dirt, the large-size glass is usually washed before being packed and shipped.

[0003] It is known that cleaning large-size glass requires a large amount of cleaning water resources, which not only brings great challenges to the compression of manufacturers' manufacturing costs, but also is a severe test of water resource protection.

[0004] In order to avoid excessive consumption of water resources, the present applicant designs a glass cleaning device which can greatly save water resources and greatly reduce water consumption. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a glass cleaning device which can efficiently recycle cleaning water resources, greatly save water resources and greatly reduce water consumption without sacrificing cleaning effect.

[0006] To solve the above technical problems, the technical scheme adopted by the application is to provide a glass cleaning device, which comprises a main frame and a glass conveying assembly and a fluid spraying assembly installed on the main frame, wherein the glass cleaning device further comprises a liquid storage pool, a liquid suction pipe and a circulating water pump; the main frame comprises two side plates extending along the left-right direction, and the two side plates are arranged at intervals in the front-rear direction; the glass conveying assembly comprises a plurality of conveying rollers arranged on the same horizontal plane and extending in the front-rear direction, and the plurality of conveying rollers are arranged at intervals in the left-right direction; the front and rear ends of each conveying roller are rotatably connected to the two side plates; the fluid spraying assembly comprises a device for spraying cleaning liquid on the surface of the glass to be cleaned moving on the plurality of conveying rollers; the liquid storage pool is installed on the main frame and located below the conveying assembly and the fluid spraying assembly, and is used for containing the cleaning liquid sprayed from the fluid spraying assembly; one end of the liquid suction pipe is in communication with the liquid storage pool, and the other end is in communication with the liquid inlet interface of the circulating water pump; the circulating water pump is fixed on the main frame and located above the glass conveying assembly and the fluid spraying assembly, and the liquid outlet interface of the circulating water pump is connected to the fluid spraying assembly. In this way, after the cleaning liquid is washed on the surface of the glass to be cleaned and falls into the liquid storage pool, the cleaning liquid in the liquid storage pool flows into the fluid spraying assembly through the liquid suction pipe under the action of the circulating water pump, thereby realizing the reuse of cleaning, greatly saving water resources and greatly reducing water consumption. It is worth mentioning that the circulating water pump is fixed on the main frame and located above the glass conveying assembly and the fluid spraying assembly, so that the circulating water pump can supply cleaning liquid downward, which can ensure that the fluid spraying assembly is provided with stable water pressure to a certain extent.

[0007] In the glass cleaning device provided by the present invention, the liquid reservoir has a bottom wall and a plurality of liquid collecting grooves formed by depressions downward from the bottom wall. The plurality of liquid collecting grooves are arranged in a rectangular array in the form of m rows and n columns on the same water surface, with m and n being positive integers, and the cross-sectional area of ​​the liquid collecting grooves gradually decreasing from top to bottom. The liquid reservoir also has a plurality of filter assemblies, which are respectively arranged in the plurality of liquid collecting spaces in a one-to-one correspondence. The filter assemblies include filter cotton for filtering fixed particles and a metal mesh for supporting the filter cotton. It should be understood that the cleaning liquid sprayed from the fluid injection assembly will scatter after being flushed on the glass to be cleaned. In order to better and faster collect the scattered cleaning liquid, the bottom of the liquid reservoir is designed to include a plurality of liquid collecting grooves arranged in an array. This allows for rapid collection of the scattered cleaning liquid. At the same time, the cross-sectional area of ​​the liquid collecting grooves gradually decreases from top to bottom, better allowing the cleaning liquid to converge in the liquid collecting grooves. The cleaning liquid in the collection channel is filtered by a filter assembly located in the liquid collection groove, ensuring that the recycled cleaning liquid does not cause secondary contamination to the glass being cleaned. The metal mesh located below the filter cotton provides uniform support for it, preventing the filter cotton from deforming after long-term use and affecting the filtering effect.

[0008] In the glass cleaning device provided by the present invention, the liquid extraction pipe includes a main pipe connected to the liquid inlet interface of the circulating water pump and multiple branch pipes connected to the main pipe. The number of branch pipes is m, and each branch pipe includes a first vertical pipe connected to the main pipe, a first horizontal pipe connected to the first vertical pipe, and multiple liquid collection pipes respectively connected to the first horizontal pipes. The number of liquid collection pipes is n, and the n liquid collection pipes are respectively connected to the bottoms of the n liquid collection grooves arranged in the same row, and the expanded lengths of the multiple liquid collection pipes are the same. In this way, the cleaning liquid in each of the liquid collection grooves can be extracted synchronously, ensuring that the cleaning liquid collected in the multiple liquid collection grooves can be efficiently and fully utilized.

[0009] In the glass cleaning device, the plurality of liquid collecting pipes comprises at least one distal liquid collecting branch pipe and a plurality of proximal liquid collecting branch pipes, the distal liquid collecting branch pipe is one of the liquid collecting pipes farthest from the first vertical pipe, the distances between the plurality of proximal liquid collecting branch pipes and the first vertical pipe are all less than the distance between the distal liquid collecting branch pipe and the first vertical pipe, and the distal liquid collecting branch pipe is connected to the bottom of one of the liquid collecting grooves farthest from the first vertical pipe in the same row of n liquid collecting grooves.

[0010] In the glass cleaning device, the main pipe comprises a plurality of transition pipe sections distributed on the same horizontal plane and a second vertical pipe section in communication with the liquid inlet interface of the circulating water pump, the plurality of transition pipe sections have the same length, one end of each of the plurality of transition pipe sections is connected to one of the first vertical pipe sections, and the other end of each of the plurality of transition pipe sections is connected to the second vertical pipe section. In this way, the length of the cleaning liquid in each of the liquid collecting grooves flowing into the liquid inlet interface of the circulating water pump is ensured to be the same, so that the speed of the cleaning liquid in each of the liquid collecting grooves being drawn out is ensured to be consistent, and the consistency of the loss of the filter cotton in each of the liquid collecting grooves is ensured, thereby facilitating the uniform replacement and maintenance in the later period.

It should be noted that the upper spraying unit and the lower spraying unit are arranged in an up-down interval, that is, there is a height difference between the two, if two pipelines are used to respectively connect the circulating water pump with the upper spraying unit and the lower spraying unit, the water pressure input into the upper spraying unit will be higher than the water pressure input into the lower spraying unit. However, through the above improvement, the water pressure difference can be greatly eliminated, because the first passage and the second passage intersect at multiple positions, and the intersection of the first passage and the second passage is communicated, after passing through the last intersection, two water flows separated from the intersection flow into the upper spraying unit and the lower spraying unit, which can greatly shorten the travel of the two water flows flowing into the upper spraying unit and the lower spraying unit respectively, thereby greatly reducing the above-mentioned water pressure difference.

It is worth mentioning that the circulating water pump 600 is fixed on the main frame 100 and located above the glass conveying assembly 200 and the fluid spraying assembly 300, so that the circulating water pump 600 can supply cleaning liquid downward, which can ensure that the fluid spraying assembly 300 is provided with stable water pressure to a certain extent.

In order to better and faster collect the scattered and dropped cleaning liquid, here, the bottom of the liquid pool 400 is designed to include a plurality of array-arranged liquid collecting grooves 41, so that the scattered and dropped cleaning liquid can be quickly collected, at the same time, the cross-sectional area of the liquid collecting groove 41 gradually decreases from top to bottom, which better enables the cleaning liquid to converge in the liquid collecting groove 41. And the filter assembly 42 arranged in the liquid collecting groove 41 filters the collected cleaning liquid, ensuring that the recycled cleaning liquid will not cause secondary pollution to the glass 800 to be cleaned. The metal mesh 422 arranged below the filter cotton 421 plays a uniform supporting role, preventing the filter cotton 421 from deforming after long-term use and affecting the filtering effect.

[0023] Further, referring to Figure 1 and Figure 5 , Figure 5 The schematic diagram of the connection relationship of the circulating water pump 600, the liquid suction pipe 700, the liquid supply pipe 500 and the fluid spraying assembly 300 provided for the embodiment is shown in Figure 5 As shown, the liquid suction pipe 700 includes a main pipe 71 in communication with the liquid inlet interface of the circulating water pump 600 and a plurality of branch pipes 72 in communication with the main pipe 71, the number of the branch pipes 72 is m, each of the branch pipes 72 includes a first vertical pipe 721 connected with the main pipe 71, a first horizontal pipe 722 connected with the first vertical pipe 721, and a plurality of liquid collecting pipes 723 respectively connected with the first horizontal pipe 722, the number of the liquid collecting pipes 723 is n, n liquid collecting pipes 723 are respectively in communication with the bottoms of n liquid collecting grooves 41 arranged in the same row, and the development lengths of the plurality of liquid collecting pipes 723 are the same.

In this way, it is ensured that the travel length of the cleaning liquid in each liquid collecting groove 41 flowing into the main pipe 71 is the same, which is beneficial to ensure that the speed of the cleaning liquid in each liquid collecting groove 41 being drawn away is consistent, thereby ensuring the consistency of the loss of the filter cotton 421 in each liquid collecting groove 41, which is beneficial to uniform replacement and maintenance later.

[0025] Further, the main pipe 71 comprises a plurality of transition pipe sections 711 distributed on the same horizontal plane and a second vertical pipe section 712 in communication with the liquid inlet interface of the circulating water pump 600, the plurality of transition pipe sections 711 have the same development length, one end of each of the plurality of transition pipe sections 711 is connected to the first vertical pipe section, and the other end is commonly connected to the second vertical pipe section 712.

It should be noted that the upper ejection unit 31 and the lower ejection unit 32 are arranged in an up-down interval, that is, there is a height difference between the two, if two pipes are used to respectively communicate the circulating water pump 600 with the upper ejection unit 31 and the lower ejection unit 32, the water pressure input into the upper ejection unit 31 will undoubtedly be higher than the water pressure input into the lower ejection unit 32. By improving as above, the water pressure difference can be greatly eliminated, because the first passage 533a and the second passage 533b intersect at multiple positions, and the intersection of the first passage 533a and the second passage 533b is communicated, after passing through the last intersection, two water flows separated at the position flow into the upper ejection unit 31 and the lower ejection unit 32, which can greatly shorten the travel of the two water flows flowing into the upper ejection unit 31 and the lower ejection unit 32 respectively, thereby greatly reducing the above-mentioned water pressure difference.
