Description

Technical Field

[0001] The utility model relates to the technical field of steam generators, in particular to a water supply device for a steam generator. Background Art

[0002] Steam generator, also called steam heat source machine (commonly known as boiler), is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of pot refers to a water container heated on fire. When using a steam generator, supplying it with water is an essential step, and water supply requires the use of a water supply device. With the continuous improvement of steam generators, the water supply device used on the top is also constantly upgraded to enable it to better meet the needs of use.

[0003] In view of this, Chinese Patent No. CN201273560Y proposes a water supply device for a steam generator. As long as there is water in the water tank, the water storage device can be kept full of water. Even when the water supply device is tilted, the water pump will not draw in air, thereby ensuring the stability of the water output of the water pump. However, there are many ways to use existing steam generators. There are steam generators used in industrial production, and there are steam generators used in high-temperature food processing. The steam generator used in food processing needs to ensure that the water quality of the water source meets the standards. Therefore, purification and filtration are required during water supply. Most of the existing water supply devices have a purification function, but the purification structure at the top is very complicated to install. It is very inconvenient to replace the new filter and clean the filter later, which increases the workload of the staff. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a water supply device for a steam generator to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a water supply device for a steam generator, comprising a water supply box, wherein the upper end of the water supply box is provided with a water purification mechanism which is convenient for disassembly and assembly;

[0006] The water purification mechanism that is easy to disassemble and assemble includes a maintenance groove opened on one side of the top of the water supply tank, a sealing cover is hingedly provided at the edge of one side of the inner wall of the maintenance groove, a mounting bracket is fixedly provided at one end of the inner wall of the water supply tank, a mounting groove is opened at the top of the mounting bracket, a filter plate is inserted through the inner wall of the mounting groove, connecting grooves are opened at the upper ends of both sides of the inner wall of the mounting groove, buckles are inserted through the inner walls of the two connecting grooves, springs are fixedly provided on one side of the inner walls of the two connecting grooves, and one end of the two springs is fixedly connected to one side of the two buckles respectively.

[0007] In one example, sealing strips are fixedly provided at the edges of both sides of the inner wall of the maintenance groove, pads are fixedly provided at the upper ends of the other two sides of the inner wall of the maintenance groove, and the bottom of the sealing cover contacts the top ends of the two pads respectively.

[0008] In one example, a water inlet pipe is inserted into the other side of the top of the water supply tank, a drain pipe is inserted into the lower end of one side of the water supply tank, and sealing valves are provided on one side of the water inlet pipe and one side of the drain pipe.

[0009] In one example, a handle is fixedly provided on the edge of one side of the outer wall of the sealing cover, and a rail is fixedly provided on the top of the water supply tank on one side of the water inlet pipe.

[0010] In one example, a sliding block is slidably provided on the inner wall of the rail, an extrusion bar is fixedly provided on the bottom of the sliding block, and the bottom of the extrusion bar contacts one side of the sealing cover.

[0011] In one example, a handle is fixedly provided at the middle position of the top of the sliding block, and limit blocks are fixedly provided at the edges on both sides of the top of the rail.

[0012] The water supply device for a steam generator proposed by the utility model can bring the following beneficial effects:

[0013] 1. In a water supply device for a steam generator, the filter plate can be taken out from a mounting bracket by squeezing the clip. After cleaning or replacing a new filter plate, the filter plate is inserted into the mounting groove and the clips at both ends are squeezed to store it in the connecting groove. After all the clips are inserted into the mounting groove, the clip is located at the upper end of the filter plate. Under the elastic force of the spring, the clip pops out of the connecting groove and is squeezed on the upper end of the filter plate to clamp it tightly on the inner wall of the mounting bracket, and its bottom is kept in close contact with the inner wall of the water supply tank, so that its bottom is sealed and not prone to water leakage, which is convenient for maintenance, thereby reducing the maintenance pressure of the staff.

[0014] 2. In the water supply device of the steam generator, when the filter plate is installed for water supply, the sealing cover is covered, and the inner wall of one end of the sealing cover contacts the sealing strips on both sides of the maintenance groove to achieve sealing, and is supported by the pad to prevent it from shifting easily. The slider is slid in the rail to squeeze the upper end of the sealing cover with the squeezing strip, thereby increasing the contact degree between the sealing cover and the maintenance groove to achieve sealing. When too much water enters the water inlet pipe, the water flow is not easy to leak out, thereby improving the sealing performance of the device. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, when the filter plate 6 is installed for water supply, the sealing cover 3 is covered, and the inner wall of one end thereof contacts the sealing baffles 10 on both sides of the maintenance groove 2 to achieve sealing, and is supported by the pad 11 to prevent it from shifting easily. The slider 15 is slid in the rail 14 so that it is squeezed on the upper end of the sealing cover 3 with the squeezing strip 16, thereby increasing the contact degree between it and the maintenance groove 2 and achieving sealing. When too much water enters the water inlet pipe 12, the water flow is not easy to leak out, thereby improving the sealing performance of the device.
