Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic glass production equipment, and specifically relates to a cleaning system for calendering rollers in the production process of photovoltaic rolled glass, and in particular to a roller washing compatible system for improving the transmittance of photovoltaic glass. Background Art

[0002] In the production process of photovoltaic rolled glass, the calendering roller of the key equipment calender is in constant contact with the molten glass, so a layer of oxides and other volatiles will stick to it. Continuing processing at this time will affect the quality of the glass, especially the light transmittance of the glass. In addition, sometimes other foreign matter sticks to the calendering roller or color difference occurs, which requires timely cleaning of the calendering roller.

[0003] There are two types of calender roller cleaning: washing the upper roller and washing the lower roller. The water volume and water pressure requirements of the two are very different. The frequency of washing the lower roller is higher, about 2-5 days / time according to the type of glass plate produced. It requires a large amount of water and a slow water force. Under the condition of ensuring the washing effect, it is necessary to avoid water splashing on the lip brick and the "onion" of the glass, causing other defects; while the frequency of washing the upper roller is lower, about 10-15 days / time, requiring a large water pressure with obvious impact. Therefore, under normal circumstances, the upper roller washing process and the lower roller washing process use their own devices and cannot be mixed. However, during long-term use, some problems may occur. For example, when washing, the pipeline pump for washing the lower roller or the high-pressure cleaning machine for washing the upper roller fails, or the gun and water pipeline for washing the roller are blocked, making the operation impossible. Repairing will delay for a long time, which will affect the production or product quality. On the other hand, the water pressure and air pressure of the two are adjusted according to the feel, which is not only time-consuming and labor-intensive, but also inaccurate.

[0004] In view of the above problems, the utility model improves the existing upper roller washing device and lower roller washing device. The basic idea is to design a system that can make the two devices compatible, which can not only ensure the requirements of both on water pressure and water volume, but also realize the rapid conversion between the two.

[0056] 1. System assembly: Assemble the lower roller washing mechanism, upper roller washing mechanism, compressed air mechanism, water storage tank 1 and switching pipe according to Figure 1 Assemble as shown.

[0057] 2. Preparation before use: Before washing the roller, fill the water storage bucket 1 with water, and use the on-site heating equipment to preheat the water in the water storage bucket 1 for standby use.

[0058] During use, when washing the lower roller during normal use, close the second switching valve 23, the intermediate valve 3, and the high-pressure cleaning machine 9, open the main valve 2 and the first switching valve 19, start the pipeline pump 4 through the first switch 21, and the water in the water storage tank 1 passes through the main water outlet pipe, the first branch, the first roller washing pipe, the first roller washing metal hose 5, the lower roller washing gun 6 and the lower roller washing nozzle 7 in sequence, that is, a single lower roller washing device is formed, and the normal lower roller washing operation can be performed; if some components of the lower roller washing mechanism fail at this time (generally, the first roller washing pipe fails), it is necessary to use some components of the upper roller washing mechanism to cooperate with the lower roller washing mechanism to complete the operation of washing the lower roller, specifically:

[0059] First, close the first switching valve 19 and the pipeline pump 4, open the second switching valve 23 and the intermediate valve 3, and start the high-pressure cleaning machine 9 through the second switch 22. At this time, the water in the water storage tank 1 passes through the main water outlet pipe, the second branch, the second roller washing pipe, the high-pressure cleaning machine 9, the third roller washing pipe, the switching pipe, the first roller washing metal hose 5, the lower roller washing gun 6 and the lower roller washing nozzle 7 in sequence. At the same time, adjust the size of the pressure regulating valve 10, observe the water flow and the reading of the first water pressure gauge 20, and after adjusting to the required state, the lower roller washing operation can be carried out. At the same time, the water in the water storage tank 1 also passes through the second roller washing metal hose 8, the upper roller washing gun 12, the bending pipe and the fine-pore upper roller washing nozzle 13 in the upper roller washing mechanism;

[0060] During normal use, when washing the upper roller, the first switching valve 19, the intermediate valve 3, and the pipeline pump 4 are closed, the main valve 2 and the second switching valve 23 are opened, and the high-pressure cleaning machine 9 is started through the second switch 22. The water in the water storage tank 1 passes through the main water outlet pipe, the second branch, the second roller washing pipe, the high-pressure cleaning machine 9, the third roller washing pipe, the second roller washing metal hose 8, the upper roller washing gun 12, the bending pipe and the fine-pore upper roller washing nozzle 13 in sequence, that is, a single upper roller washing device is formed, and the normal upper roller washing operation can be performed; if some components of the upper roller washing mechanism fail at this time (generally the second roller washing pipe or the third roller washing pipe fails), it is necessary to use some components of the lower roller washing mechanism to cooperate with the upper roller washing mechanism to complete the operation of washing the upper roller, specifically:

[0061] First, close the second switching valve 23 and the high-pressure cleaning machine 9, open the first switching valve 19, the pipeline pump 4, the intermediate valve 3, and open the compressed air valve 15 and the compressed air regulating valve at the same time.

At the same time, the water in the water storage tank 1 also passes through the first roller washing metal hose 5, the lower roller washing gun 6 and the lower roller washing nozzle 7 in the lower roller washing mechanism.

[0062] Note: Regardless of whether you are washing the upper roller or the lower roller, all valves must be closed after washing. At the same time, the power supply of the pipeline pump 4 or the high-pressure cleaning machine 9 must be cut off to prevent scale from affecting the functions of the valves, pipeline pump 4 or the high-pressure cleaning machine 9.

[0063] During cleaning, adjust the water flow or air path in the lower roller washing mechanism, upper roller washing mechanism or compressed air mechanism to the required value with reference to the corresponding water pressure gauge and air pressure gauge. At the same time, record the pressure gauge reading after cleaning as a reference for the next adjustment for digital management.

[0064] Several innovative features of this utility model:

[0065] 1. The utility model combines a single lower roller washing device and an upper roller washing device into one, performs compatibility modification and is convenient for switching.

[0066] 2. Since the pipeline pump 4 used in the lower roller washing mechanism has a low pressure, and the high-pressure cleaning machine 9 used in the upper roller washing mechanism has a high pressure, in order to meet the pressure requirements, compared with the prior art, this application mainly has the following improvements:

[0067] 1) When washing the lower roller with the upper roller washing device, the lower roller washing nozzle 7 near the end of the lower roller washing gun 6 is increased to multiple nozzles, which not only ensures the pressure but also shortens the roller washing time; a pressure reducing valve 10 is set on the switching pipe to control and stabilize the pressure; a water pressure gauge and an air pressure gauge are added to achieve timely adjustment to the required pressure before washing the roller.

[0068] 2) When the upper roller is washed with the lower roller washing device, the number of the fine-hole upper roller washing nozzles 13 on the bent tube at the end of the upper roller washing gun 12 is reduced from two to one, which can reduce energy consumption and ensure the cleaning effect; a set of compressed air mechanism is added to improve the cleaning performance of the upper roller washing gun 12.

[0069] In the production process of photovoltaic rolled glass, the calendering rollers need to be cleaned in time to improve the light transmittance of the glass or prevent the calendering rollers from being stuck with other foreign matter or having color difference. There are two types of cleaning for the calendering rollers: washing the upper roller and washing the lower roller. In the prior art, each has its own cleaning device, which cannot be exchanged or switched, which is extremely inconvenient. The present application proposes a system that can realize the switching between the upper roller washing device and the lower roller washing device. Once one of the devices fails, they can be interchanged for compatibility.

[0070] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
