Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy technology, specifically a descaling and cleaning machine for solar glass vacuum tube collectors. Background Technology
[0002] Existing solar glass vacuum tube collector descaling and cleaning machines produce a large amount of scale when the internal circulating water of the solar collector is hard. This scale adheres to the manifold and the tube walls of the vacuum tubes, greatly affecting the solar collector's heat collection efficiency and the service life of various components. To address these issues, we have designed a solar glass vacuum tube collector descaling and cleaning machine. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a descaling and cleaning machine for solar glass vacuum tube collectors. The technical solution adopted by this utility model to solve its technical problem is as follows: The solar glass vacuum tube collector descaling and cleaning machine includes a dosing tank, a vortex air pump, a circulating water pump, a control cabinet, a negative pressure protection valve, a dosing port, a pressure sensor, and a drain port. The dosing tank is characterized by having a dosing port located at the top, a negative pressure protection valve located at the upper left of the dosing tank, a drain port located at the lower left of the dosing tank, and a pressure sensor located at the lower right of the dosing tank. The dosing tank is connected to one end of the vortex air pump, and the other end of the dosing tank is connected to the circulating water pump. The dosing tank is also connected to the control cabinet.
[0004] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0005] The solar glass vacuum tube collector descaling and cleaning machine of this utility model uses a vortex air pump to pressurize and depressurize the air, so that the device can have an air filling protection.
[0006] This device can regulate the pressure of mechanical equipment by setting a pressure sensor; by setting a negative pressure protection valve, when the negative pressure inside the system or equipment exceeds the allowable value, the negative pressure protection valve will automatically open to draw in air to balance the pressure, prevent the equipment from being damaged due to excessive negative pressure, and protect the equipment safety.
[0007] This device adds descaling agent into the solar collector. After descaling is completed, the residual liquid in the dosing tank is discharged through the drain port, which can effectively remove scale from the solar collector and vacuum tubes. Attached Figure Description

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0011] like Figure 1 As shown, the solar glass vacuum tube collector descaling and cleaning machine includes a dosing tank 1, a vortex air pump 2, a circulating water pump 3, a control cabinet 4, a negative pressure protection valve 5, a dosing port 6, a pressure sensor 7, and a drain port 8. The dosing port 6 is located at the top of the dosing tank 1, the negative pressure protection valve 5 is located at the upper left of the dosing tank 1, the drain port 8 is located at the lower left of the dosing tank 1, and the pressure sensor 7 is located at the lower right of the dosing tank 1. One end of the dosing tank 1 is connected to the vortex air pump 2, and the other end of the dosing tank 1 is connected to the circulating water pump 3. The dosing tank 1 is connected to the control cabinet 4.
[0012] Mechanism of action:
[0013] First, add the descaling agent into the dosing tank 1 through the dosing port 6 and lock the dosing tank opening. Then, close the valve on the pipe connected to the hot water storage tank and open the valve on the pipe connected to the descaling and cleaning device for the solar water heater collector. Next, start the cleaning machine's vortex air pump 2, and automatically adjust the system pressure via the pressure sensor 7. Then, start the circulating water pump 3 to replenish the descaling agent into the collector. Finally, after descaling is complete, drain the remaining liquid in the dosing tank 1 through the drain port 8.
