Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a vacuum negative pressure drainage device. Background Art

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. When using vacuum negative pressure to absorb substances, the vacuum pump is used to generate negative pressure at the suction end to absorb the substances.

[0003] The existing vacuum pump does not separate the water in the sucked material when sucking, so the water will enter the vacuum pump and cause certain damage to the vacuum pump, thus affecting the service life of the vacuum pump. Therefore, we propose a vacuum negative pressure drainage device. Utility Model Content

[0004] The purpose of the utility model is to provide a vacuum negative pressure drainage device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum negative pressure drainage device, comprising a water collecting tank, wherein the upper side of one end of the water collecting tank is fixedly connected to a water inlet valve, the top of the water collecting tank is fixedly connected to an angle valve and a first pneumatic valve, the other end of the water collecting tank is connected to a second pneumatic valve, a liquid level meter and a controller are respectively fixed on both sides of the front side wall of the water collecting tank, and the bottom of the water collecting tank is fixedly connected to a drainage valve.

[0006] By adopting the above technical scheme, the angle valve and the vacuum pump are connected, so that negative pressure is generated in the water collecting tank, so that the water inlet valve can introduce the water of the material after being sucked and isolated into the water collecting tank. At this time, the water in the water collecting tank will drop due to its own gravity and gather at the bottom of the water collecting tank, which can help prevent water from entering the vacuum pump. At the same time, the liquid level meter monitors the water level and feeds back to the controller. After the water level reaches a certain height, the water inlet valve and the angle valve will be closed, and the first pneumatic valve and the second pneumatic valve will be opened, and the drain valve will be opened at the same time, so that the water can be discharged directly, which helps to prevent water from entering the vacuum pump and causing damage to it.

[0007] As a preferred embodiment of the utility model, a filtering mechanism is fixed on the top of the inner cavity of the water collecting tank, and the filtering mechanism includes a mesh frame, and the mesh frame is fixed at the top of the inner cavity of the water collecting tank corresponding to the angle valve, and a filter cotton plate is fixed to the bottom of the inner cavity of the mesh frame, and a mesh plate is attached to the top of the filter cotton plate, and electric push rods are fixed on both sides of the top of the mesh plate, and the outer ends of the electric push rods are connected to the top of the inner cavity of the mesh frame.

[0008] By adopting the above technical solution, before the gas enters the angle valve, it will pass through the filtering mechanism, so that it can be filtered again by the filter cotton plate, which is beneficial to further prevent water vapor from invading the vacuum pump. At the same time, when draining water, the electric push rod drives the mesh plate to pressurize the filter cotton plate to squeeze out the filtered water, which is beneficial to improve the water absorption performance of the filter cotton plate when it is used again.

[0009] As a preferred embodiment of the present utility model, a pressure gauge is fixedly connected to one side of the top of the water collecting tank.

[0010] By adopting the above technical solution and setting up a pressure gauge, the internal pressure of the water collecting tank can be detected.

[0011] As a preferred embodiment of the utility model, wedge-shaped blocks are fixed on both sides of the bottom of the inner cavity of the water collecting tank.

[0012] By adopting the above technical solution and setting the wedge-shaped block, water can be directed to the drain valve, thereby improving the drainage effect.

[0013] As a preferred embodiment of the utility model, support plates are fixed to both sides of the bottom of the water collecting tank, and a mounting plate is fixed to the tail end of the support plate.

[0014] By adopting the above technical solution and setting the mounting plate, it is convenient to install and fix the entire device.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The vacuum negative pressure drainage device of the technical solution of the present application is connected with the vacuum pump through an angle valve, so that after the suction material is isolated, water can enter the inner cavity of the water collecting tank along the water inlet valve. At this time, the water in the water collecting tank will drop due to its own gravity and gather at the bottom of the water collecting tank, which can help prevent water from entering the vacuum pump. At the same time, the liquid level meter monitors the water level and feeds back to the controller. When the water level reaches a certain height, the water inlet valve and the angle valve will be closed, and the first pneumatic valve and the second pneumatic valve will be opened, and the drainage valve will be opened at the same time, so that the water can be directly drained, which is conducive to preventing water from entering the vacuum pump and causing damage to it;

[0017] A mesh frame is fixed at the angle valve corresponding to the inner cavity of the water collecting pipe, and a filter cotton plate is arranged inside the mesh frame, so that a small amount of water vapor can be absorbed again, which is beneficial to further prevent water vapor from invading the vacuum pump. At the same time, when draining water, the electric push rod drives the mesh plate to pressurize the filter cotton plate to squeeze out the filtered water, which is beneficial to improve the water absorption performance of the filter cotton plate when it is used again.

A liquid level meter 18 and a controller 19 are respectively fixed to both sides of the front side wall of the water collecting tank 1, and a drainage valve 17 is fixedly connected to the bottom of the water collecting tank 1. The liquid level meter 18 can detect the water level and feed back the water level signal to the controller 19. The controller 19 can issue working instructions to the water inlet valve 13, the angle valve 14, the first pneumatic valve 15, the second pneumatic valve 16, and the drainage valve 17;

[0027] In actual use, the angle valve 14 is connected to the vacuum pump, so that the water collecting tank 1 generates negative pressure, so that the water inlet valve 13 can introduce the water of the material after being sucked and isolated into the water collecting tank 1. At this time, the water in the water collecting tank 1 will drop due to its own gravity, and thus gather at the bottom of the water collecting tank 1, which can help prevent water from entering the vacuum pump. At the same time, the liquid level meter 18 monitors the water level and feeds back to the controller 19. When the water level reaches a certain height, the water inlet valve 13 and the angle valve 14 will be closed, and the first pneumatic valve 15 and the second pneumatic valve 16 will be opened, and the drain valve 17 will be opened at the same time, so that the water can be directly drained, which is helpful to prevent water from entering the vacuum pump and causing damage to it;

[0028] Furthermore, support plates 11 are fixed to both sides of the bottom of the water collecting tank 1, and mounting plates 12 are fixed to the tail ends of the support plates 11. The arrangement of the mounting plates 12 facilitates the installation and fixing of the entire device.

[0029] Furthermore, a pressure gauge is fixedly connected to one side of the top of the water collecting tank 1, and the setting of the pressure gauge can detect the internal pressure of the water collecting tank 1;

[0030] It is worth mentioning that wedge blocks 3 are fixed on both sides of the bottom of the inner cavity of the water collecting tank 1. The arrangement of the wedge blocks 3 enables water to be directed to the drain valve 17, thereby improving the drainage effect;

[0031] like Figure 1 and 2 , 3; a filter mechanism 2 is fixed to the top of the inner cavity of the water collecting tank 1, and the filter mechanism 2 includes a mesh frame 21, which is fixed to the top of the inner cavity of the water collecting tank 1 at the corresponding angle valve 14, a filter cotton plate 22 is fixed to the bottom of the inner cavity of the mesh frame 21, a mesh plate 23 is attached to the top of the filter cotton plate 22, and electric push rods 24 are fixed on both sides of the top of the mesh plate 23, and the outer ends of the electric push rods 24 are connected to the top of the inner cavity of the mesh frame 21;

[0032] Before the gas enters the angle valve 14, it will pass through the filtering mechanism 2, so that it can be filtered again by the filter cotton plate 22, which is beneficial to further prevent water vapor from invading the vacuum pump. At the same time, when draining water, the electric push rod 24 drives the mesh plate 23 to pressurize the filter cotton plate 22 to squeeze out the filtered water, which is beneficial to improve the water absorption performance of the filter cotton plate 22 when it is used again.

[0033] The implementation principle of the vacuum negative pressure drainage device of the present application is as follows: in actual use, the angle valve 14 is connected to the vacuum pump, so that the water collecting tank 1 generates negative pressure, so that the water inlet valve 13 can introduce the water of the substance after being sucked and isolated into the water collecting tank 1. At this time, the water in the water collecting tank 1 will drop due to its own gravity, and thus gather at the bottom of the water collecting tank 1, which can help prevent water from entering the vacuum pump. At the same time, the liquid level meter 18 monitors the water level and feeds back to the controller 19. When the water level reaches a certain height, the water inlet valve 13 and the angle valve 14 will be closed, and Open the first pneumatic valve 15 and the second pneumatic valve 16, and open the drain valve 17 at the same time, so that the water can be drained directly, which is beneficial to prevent water from entering the vacuum pump and causing damage to it. Before the gas enters the angle valve 14, it will pass through the filtering mechanism 2, so that it can be filtered again by the filter cotton plate 22, which is beneficial to further prevent water vapor from invading the vacuum pump. At the same time, when draining water, the electric push rod 24 drives the mesh plate 23 to pressurize the filter cotton plate 22 to squeeze out the filtered water, which is beneficial to improve the water absorption performance of the filter cotton plate 22 when it is used again.
