Description

Technical Field

[0001] The utility model relates to the technical field of sand filter tanks, in particular to an exhaust structure of a sand filter tank in a sewage station. Background Art

[0002] Highland barley wine production is a complex and delicate process, and wastewater treatment is crucial for ensuring a clean production environment and consistent product quality. As a key piece of equipment in the wastewater treatment system, the sand filter tank's primary function is to filter out suspended matter and impurities from the wastewater, ensuring smooth processing of subsequent treatment steps. However, the performance and efficiency of the sand filter tank are often affected by the operating conditions of its supporting equipment, particularly the exhaust valve. The exhaust valve's primary function is to release accumulated gases within the tank to ensure continuous and stable wastewater treatment. The exhaust valve is typically located at the top of the sand filter tank. However, operational issues with the exhaust valve include poor ventilation, clogging, and frequent maintenance. This requires workers to climb the tank to inspect, maintain, or replace the exhaust valve. This is especially true when the sand filter tank is operating, where the surface can be slippery and harmful gases can accumulate inside. This makes the process of climbing in and out of the tank particularly dangerous and reduces safety.

[0003] There may already be technical means to solve the above problems in the existing technology, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0004] In order to solve the problems raised in the background technology, the present invention is implemented through the following technical solutions: a sewage station sand filter tank exhaust structure, comprising a sand filter tank body, an exhaust port is installed at the top of the sand filter tank body, and an exhaust structure is installed at one end of the exhaust port;

[0012] Beneficial effects

[0013] The utility model provides an exhaust structure for a sand filter tank in a sewage station. Compared with the prior art, it has the following beneficial effects: under the connection of an extension pipe, the valve is located at the lower end of one side of the sand filter tank body, which is convenient for operators to perform exhaust work and convenient for maintaining the valve. There is no need for operators to climb the sand filter tank body, which improves the safety factor. The extension pipe is connected to one end of the exhaust port, so that the gas generated in the sand filter tank body is discharged from the exhaust port into the extension pipe, and exhaust is achieved by operating the valve. When exhausting, the blades in the display component are forced to rotate, and the operator can observe the rotation state of the blades in the transparent box at the end from the outside. When the blades no longer drive the rotating sleeve to rotate, it proves that the gas in the sand filter tank body is completely discharged. At this time, the valve is closed, which is convenient for the operator to understand the exhaust situation in the sand filter tank body and prevents the valve from being closed before the gas is completely discharged.

[0019] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0020] Example: See Figure 1-4 This technical solution is designed to solve the problem that workers need to climb the tank body when inspecting, maintaining or replacing the exhaust valve. Especially when the sand filter tank is in operation, the tank surface may be slippery and harmful gases may accumulate inside, making the process of climbing up and down the tank body particularly dangerous and having a low safety factor. The detailed technical solution is as follows;

[0021] A sewage station sand filter tank exhaust structure includes a sand filter tank body 1, an exhaust port 2 is installed at the top of the sand filter tank body 1, and an exhaust structure is installed at one end of the exhaust port 2;

[0022] Specifically, the exhaust structure includes an extension tube 3, which is installed at one end of the exhaust port 2, a valve 4 is installed at one end of the extension tube 3, and a display component is installed at one end of the valve 4;

[0023] It should be noted that, when the extension pipe 3 is connected, the valve 4 is located at the lower end of one side of the sand filter tank body 1, which is convenient for the operator to perform exhaust work and to maintain the valve 4. The operator does not need to climb the sand filter tank body 1, which improves the safety factor. The extension pipe 3 is connected to one end of the exhaust port 2, so that the gas generated in the sand filter tank body 1 is discharged from the exhaust port 2 into the extension pipe 3, and exhaust is achieved by operating the valve 4;

[0024] More specifically, the display assembly includes an end transparent box, which includes a connecting neck tube 5 and an expansion tube 6. The connecting neck tube 5 is installed at one end of the valve 4, and the expansion tube 6 is installed at one end of the connecting neck tube 5. A support rod 7 is fixedly inserted into the inner wall of the expansion tube 6, and a rotating sleeve 8 is movably mounted on the support rod 7. A plurality of blades 9 are installed in a circular array on the outer wall of the rotating sleeve 8. The blades 9 are arranged corresponding to one end of the connecting neck tube 5. A funnel-shaped tube 10 is installed on the inner top surface of the expansion tube 6, and the funnel-shaped tube 10 is coaxially installed with the connecting neck tube 5.

[0025] It should be noted that during exhaust, the gas in the extension tube 3 passes through the valve 4 and the connecting neck tube 5 and enters the expansion tube 6. The gas discharged from the connecting neck tube 5 acts on the blades 9. The blades 9 are forced to drive the rotating sleeve 8 to rotate on the support rod 7, and the gas is then discharged from the lower end of the expansion tube 6. The end transparent box is made of transparent material, and the operator can observe the rotation state of the blades 9 in the end transparent box from the outside. When the blades 9 no longer drive the rotating sleeve 8 to rotate, it proves that the gas in the sand filter tank body 1 is exhausted. At this time, the valve 4 is closed, which makes it easier for the operator to understand the exhaust status of the sand filter tank body 1 and prevents the valve 4 from being closed before the gas is exhausted.

[0026] As a preference, further, the extension tube 3 is an n-shaped structure;

[0027] As a preference, further, the inner diameter of the upper end of the funnel-shaped tube 10 is the same as the inner diameter of the connecting neck tube 5, and the inner diameter of the lower end of the funnel-shaped tube 10 is smaller than the inner diameter of the connecting neck tube 5; after the gas is discharged from the connecting neck tube 5, it is discharged into the expansion tube 6 through the funnel-shaped tube 10. The lower end of the funnel-shaped tube 10 is used to increase the flow rate of the gas. After acting on the blade 9, the speed of rotation of the blade 9 can be accelerated, and the rotation phenomenon of the blade 9 can be magnified, which is convenient for the operator to observe;

[0028] As a preferred embodiment, further, a dustproof net 11 is installed at the lower end of the inner wall of the expansion tube 6 to prevent dust from entering the interior of the expansion tube 6 from one end of the expansion tube 6.

[0029] As a preference, further, the exhaust port 2 and the extension pipe 3 are connected by a flange connection, the valve 4 and the extension pipe 3 are connected by a flange connection, and the valve 4 and the connecting neck pipe 5 are connected by a flange connection;

[0030] Preferably, further, a bearing 12 is provided between the rotating sleeve 8 and the support rod 7 to assist the rotating sleeve 8 in rotating on the support rod 7 .

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
