Description

Technical Field

[0001] This utility model relates to the field of vacuum workstations, specifically to a vacuum workstation with self-circulating cleaning. Background Technology

[0002] The current method of collecting and discharging domestic sewage is gradually shifting from traditional gravity drainage to vacuum drainage. Existing vacuum workstations include a vacuum tank and a vacuum pulverizing sewage pump. The vacuum pulverizing sewage pump creates a vacuum inside the tank to achieve vacuum drainage, while also incorporating a pulverizing device to prevent solid debris in the sewage from clogging the vacuum pipeline. In some applications, the vacuum workstation is used temporarily and needs to be disassembled, packed, and transported after use. Before disassembly, the equipment must be thoroughly rinsed to prevent the spillage of contaminants. Traditional cleaning methods involve connecting the equipment to a water source for rinsing, which has drawbacks such as incomplete cleaning and high water consumption. Utility Model Content

[0003] To address the problems of inadequate cleaning and excessive water usage in existing vacuum workstations, this invention provides a self-circulating cleaning vacuum workstation that solves these issues.

[0004] A vacuum workstation with self-circulating cleaning includes a sewage inlet pipe, a vacuum tank, a vacuum pulverizing sewage pump, a water-air separator, and a sewage outlet pipe connected in sequence. It also includes a circulation pipe and a water supply pipe. One end of the circulation pipe is connected to the sewage outlet pipe, the middle is connected to the water supply pipe, and the other end is connected to the vacuum tank. A first valve is provided downstream of the sewage outlet pipe, a second valve is provided between the circulation pipe and the sewage outlet pipe, and a third valve is provided on the water supply pipe.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please also refer to Figures 1 to 3 These are schematic diagrams and cross-sectional views of the vacuum workstation with self-circulating cleaning provided by this utility model from two different perspectives.

[0021] The vacuum workstation with self-circulating cleaning includes a vacuum tank 1, a vacuum pulverizing and sewage pump 2, a water-air separator 3, and a controller 4.

[0022] Vacuum tank 1 has a horizontal structure with support legs at the bottom of the side wall, a slag discharge pipe 11 at the bottom of the end face, a controller 4 at the top of the side wall, and two inlet pipes 12, a connecting pipe 13, and an installation platform at the top of the side wall. The two inlet pipes 12 are arranged side by side on one side of vacuum tank 1, and the connecting pipe 13 is located on the opposite side of vacuum tank 1 and is inserted into the bottom of vacuum tank 1.

[0023] Two vacuum pulverizing sewage pumps 2 are installed side by side on the installation platform. The inlet and outlet of the vacuum pulverizing sewage pumps 2 are both facing upwards, and each is equipped with a fourth valve 21. The connecting pipe 13 has a T-shaped structure. The lower end of the vertical pipe is inserted into the bottom of the vacuum tank 1, and the two ends of the horizontal pipe are connected to the fourth valve 21 at the inlet of the two vacuum pulverizing sewage pumps 2, respectively. The side wall of the horizontal pipe is equipped with a pressure measuring pipe 14.

[0024] The fourth valve 21 at the outlet of each of the two vacuum pulverizing sewage pumps 2 is connected sequentially to the water-air separator 3 and the check valve 31. The pipe between the water-air separator 3 and the check valve 31 is bent downwards, so that the check valve 31 faces downwards, and is connected to the horizontally arranged sewage pipe 5. One end of the sewage pipe 5 is closed, and the other end is equipped with a first valve 51. The middle is connected to the circulation pipe 6 through a second valve 52.

[0025] The one-way valve 31 allows gas to flow unidirectionally from the water-gas separator 3 to the drain pipe 5, without affecting the normal operation of the vacuum pulverizing sewage pump 2. After the vacuum pulverizing sewage pump 2 stops working, the one-way valve 31 rebounds, preventing external gas from entering and forming a seal. At the same time, atmospheric pressure further compresses the one-way valve 31, forming a stable sealing effect.

[0026] The circulation pipe 6 extends downward and is inserted into the vacuum tank 1 between the two sewage inlet pipes 12. At its end, a spraying mechanism 61 is provided to spray water into various parts of the vacuum tank 1.

[0027] A water supply pipe 62 and an air intake pipe 63 are connected in the middle of the circulation pipe 6, and a third valve 64 and a fifth valve 65 are respectively provided. The first to fifth valves are all manual ball valves.

[0028] The controller 4 is electrically connected to the two vacuum pulverizing sewage pumps 2 and the vacuum pressure sensor in the pressure measuring pipe 14. One of the two sewage inlet pipes 12 is in use and the other is on standby, with the flange of the standby sewage inlet pipe 12 sealed; one of the two vacuum pulverizing sewage pumps 2 is in use and the other is on standby, with the two fourth valves 21 of the standby vacuum pulverizing sewage pump 2 closed, and the controller 4 does not control its start.

[0029] In operation, a vacuum pulverizing and sewage discharge pump 2 is started first to evacuate the vacuum tank 1. Based on the data obtained by the vacuum pressure sensor, the controller 4 controls the vacuum pulverizing and sewage discharge pump 2 to shut down after the target vacuum level is reached.

[0030] Waste enters the vacuum tank 1 through the inlet pipe 12. After simple treatment in the vacuum tank 1, it is discharged through the outlet pipe 5 via the connecting pipe 13, the vacuum pulverizing and sewage pump 2, and the water-air separator 3. Waste deposited at the bottom of the vacuum tank 1 is periodically cleaned from the slag outlet 11.

[0031] During cleaning, disconnect the inlet pipe 12 and start one or two vacuum pulverizing and draining pumps 2 to empty the vacuum tank 1. Then close the first valve 51, open the second valve 52, and open the third valve 64. At this time, water is sprayed from the water supply pipe 62 through the circulation pipe 6 and the spraying mechanism 61 to various parts of the vacuum tank 1. After the cleaning water volume is reached, close the third valve 64 to stop the water supply.

[0032] The vacuum pulverizing and sewage pump 2 is started, causing the cleaning water to circulate and flush between the vacuum tank 1, connecting pipe 13, vacuum pulverizing and sewage pump 2, water-air separator 3, sewage pipe 5, circulation pipe 6, and spraying mechanism 61. After flushing for a certain period of time, the first valve 51 is opened and the second valve 52 is closed, allowing the cleaning water to be discharged from the sewage pipe 5. This process can be repeated multiple times until the interior is thoroughly cleaned.

[0033] Furthermore, cleaning agents can be added to the water source, and the solution can be added from the water supply pipe 62 to the circulation pipe 6 to achieve a better cleaning effect.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
