[0001] The utility model relates to the technical field of medical equipment, in particular to an integral tilted-mounted medical vacuum station based on PLC control. Background Art

[0002] The ‌‌Medical Vacuum Station‌ is a device specially designed for medical institutions. It mainly provides the vacuum source for the medical gas central station and is widely used in medicine, medical care and other fields. The medical vacuum station is usually composed of a vacuum pump unit, a pipe network system, and ward terminal equipment. The negative pressure source is provided by the vacuum pump unit, and the system pipeline reaches the required negative pressure value through suction, thereby generating suction at the terminals of the operating room, emergency room and each ward for medical use.

[0003] In the prior art, most of the medical vacuum stations on the market are scattered and connected, and their overall size is large and cannot be moved as a whole. When they need to be used in special venues, they need to be disassembled and transported before they can be moved, and they also need to be temporarily taken over and debugged on site, which brings great inconvenience to medical staff during use, thereby affecting their efficiency. Summary of the invention

[0004] Based on this, the purpose of the utility model is to provide an integral tilted medical vacuum station based on PLC control to solve the technical problem of the inconvenience of overall transportation of the medical vacuum station.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integral tilted medical vacuum station based on PLC control, comprising a base, a vacuum tank is provided on the top of the base, a pressure gauge matching the vacuum tank is provided on the top of the base, two groups of vacuum pumps are provided on one side of the vacuum tank, the vacuum tank and the vacuum pump are connected by connecting pipes, and one side of the two groups of vacuum pumps is fixedly connected with an output pipe.

[0006] By adopting the above technical solution, the gas inside the vacuum tank enters the output pipeline through two groups of vacuum pumps and multiple groups of connecting pipes, and at the same time, the gas is processed and stored by the vacuum tank.

[0007] Furthermore, two groups of bacterial filters are arranged on the other side of the vacuum tank, and the vacuum tank and the bacterial filters are connected through a connecting pipe pipeline, and an input pipeline is arranged on the surface of the connecting pipe on one side of the bacterial filter.

[0008] By adopting the above technical solution, the input pipeline is connected to the bacterial filter through a connecting pipe, so as to achieve the effect of absorbing and filtering the gas. At the same time, through the structure of multiple sets of valves and two sets of bacterial filters, the bacterial filter can be maintained and replaced without stopping operation.

[0009] Furthermore, an automatic control cabinet is arranged on the top of the base, and the automatic control cabinet is electrically connected to the two groups of vacuum pumps.

[0010] By adopting the above technical solution, the automatic control cabinet is electrically connected to the two groups of vacuum pumps, so as to achieve the function of controlling the switching of the two groups of vacuum pumps.

[0011] Furthermore, the base, the bacterial filter, the vacuum tank, the automatic control cabinet and the two sets of vacuum pumps are all fixedly connected by a tilted steel frame.

[0012] By adopting the above technical solution, all components are compactly installed on the tilted steel frame, and anchor bolt fixing holes are reserved. Users only need to move the vacuum station to the designated position for use without re-taking over and debugging, thereby improving the use efficiency.

[0013] Furthermore, valves are arranged on the surfaces of the plurality of connecting pipes, and two valves are arranged between each bacterial filter and each vacuum pump.

[0014] By adopting the above technical solution, multiple groups of valves cooperate with each other, so as to achieve the effect of controlling and locking each group of bacteria filters and vacuum pumps separately, thereby facilitating the overall use.

[0015] Furthermore, a motor is provided on one side of the vacuum pump, and a heat dissipation system is provided on the other side of the vacuum pump.

[0016] By adopting the above technical solution, the vacuum pump achieves the functions of providing power and dissipating heat to extend the service life through the structure of the motor and the heat dissipation system.

[0017] In summary, the utility model mainly has the following beneficial effects: the utility model uses two groups of vacuum pumps 5 to work together under the command of the automatic control cabinet, wherein when the pressure of the connecting pipe is lower than a certain set value, the pressure sensor feeds back information to the automatic control cabinet, and the PLC instructs one of the vacuum pumps to start working. If the vacuum value of the pipeline has not reached the set value within the set time, the PLC instructs the other pump to start. At this time, the two pumps work together to make the vacuum value in the pipeline reach the set value, and the machine stops working, thereby realizing the cycle operation of the two pumps and extending the service life of the pumps. At the same time, all components are installed on the base through the tilted steel frame, so that the overall structure does not need to be disassembled when it is displaced.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A PLC-controlled integrated tilt-mounted medical vacuum station, such as Figure 1-Figure 4 As shown, it includes a base 1, a vacuum tank 2 is provided at the top of the base 1, a pressure gauge 3 matched therewith is provided at the top of the base 1, two groups of vacuum pumps 5 are provided on one side of the vacuum tank 2, the vacuum tank 2 and the vacuum pump 5 are connected through a connecting pipe 4, one side of the two groups of vacuum pumps 5 is fixedly connected with an output pipe 8, and two groups of bacterial filters 10 are provided on the other side of the vacuum tank 2, the vacuum tank 2 and the bacterial filter 10 are connected through a connecting pipe 4, and an input pipe 11 is provided on the surface of the connecting pipe 4 on one side of the bacterial filter 10, wherein when the filtered gas enters the vacuum tank 2 through the connecting pipe 4 and is processed by the vacuum tank 2, the gas inside the vacuum tank 2 is then driven by the two groups of vacuum pumps 5 and the connecting pipe 4, so that the filtered gas enters the output pipe 8;

[0026] Specifically, the two vacuum pumps 5 work together under the command of the automatic control cabinet 12. When the pressure of the connecting pipe 4 is lower than a certain set value, the pressure sensor feeds back information to the automatic control cabinet 12, and the PLC instructs one of the vacuum pumps 5 to work. If the vacuum value in the connecting pipe has not reached the set value within the set time, the PLC instructs the other vacuum pump 5 to start at the same time. At this time, the two vacuum pumps 5 work together, and the machine stops working after the vacuum value in the connecting pipe reaches the set value.

[0027] Furthermore, when the vacuum value in the connecting pipe 4 drops to the set value again, the PLC restarts the vacuum pump 5. In order to extend the service life of the vacuum pump 5, another vacuum pump 5 is started this time. If the vacuum value cannot be reached within the rated time, the first group of vacuum pumps 5 is started to work, thereby realizing the cycle operation of the two vacuum pumps and achieving the effect of extending the service life of the vacuum pump 5.

[0028] See also Figure 1 and Figure 2 Valves 9 are provided on the surfaces of the multiple groups of connecting pipes 4, and two groups of valves 9 are provided between each group of bacterial filters 10 and each group of vacuum pumps 5, wherein the input pipeline 11 is connected to the bacterial filter 10 through the connecting pipe 4, so as to achieve the effect of absorbing and filtering the gas. At the same time, through the structure of the multiple groups of valves 9 and the two groups of bacterial filters 10, the bacterial filter 10 can be maintained and replaced without stopping operation.

[0029] See also Figure 1 and Figure 2 The base 1, the bacterial filter 10, the vacuum tank 2, the automatic control cabinet 12 and the two sets of vacuum pumps 5 are all fixedly connected by a tilted steel frame 13, wherein all components are compactly mounted on the tilted steel frame 13, and anchor bolt fixing holes are reserved, and the user only needs to move the vacuum station to the designated position for use, without the need for re-taking over and debugging, thereby improving the use efficiency.

[0030] The working principle of the utility model is as follows: when in use, the power is turned on, and the user connects the input pipe 11 with the ward pipeline, and then the connecting pipe 4 is used to introduce the bacteria filter 10 for filtering. By setting two groups of bacteria filters 10, the two groups of bacteria filters 10 are used in turn. When one group of bacteria filters 10 is to be maintained and replaced, the two groups of valves 9 before and after it are closed to disconnect it from the connecting pipe 4, and then the bacteria filter 10 that needs to be replaced is replaced and maintained;

[0031] During use, the filtered gas enters the vacuum tank 2 through the connecting pipe 4 and is processed by the vacuum tank 2, and then the gas inside the vacuum tank 2 is driven by two sets of vacuum pumps 5 and the connecting pipe 4, so that the filtered gas enters the output pipe 8;

[0032] Specifically, the two vacuum pumps 5 work together under the command of the automatic control cabinet 12. When the pressure of the connecting pipe 4 is lower than a certain set value, the pressure sensor feeds back information to the automatic control cabinet 12, and the PLC instructs one of the vacuum pumps 5 to work. If the vacuum value in the connecting pipe has not reached the set value within the set time, the PLC instructs the other vacuum pump 5 to start at the same time. At this time, the two vacuum pumps 5 work together, and the machine stops working after the vacuum value in the connecting pipe reaches the set value.

[0033] Furthermore, when the vacuum value in the connecting pipe 4 is reduced to the set value again, the PLC restarts the vacuum pump 5. To extend the service life of the vacuum pump 5, another vacuum pump 5 is started to work. If the vacuum value cannot be reached within the rated time, the first group of vacuum pumps 5 is started to work, thereby realizing the round-robin operation of the two vacuum pumps, thereby extending the service life of the vacuum pump 5.

[0034] During use, all components are compactly mounted on the tilted steel frame 13, and anchor bolt fixing holes are reserved. Users only need to move the vacuum station to the designated position for use without re-connection and debugging, thereby improving the use efficiency.

[0035] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model.
