Description
Technical Field
[0001] The utility model relates to the technical field of vacuum pump filtration, in particular to a vacuum pump filtration device for a paper towel machine which is flexible in use. Background Art
[0002] Paper towels are items frequently used in people's daily lives and have a huge market demand. In order to meet market demand, factories will use automated equipment to produce paper towels. In the production process of paper towels, they need to use machinery to fold and package the paper towels. At this time, in order to avoid dust in the paper towels, the processing point will be vacuumed. In this process, dust and paper scraps will flow with the air. In order to ensure the continuous and stable operation of the vacuum pump, a filter device needs to be installed at the air inlet end of the vacuum pump.
[0003] The existing filtering device has a simple structure and is insufficient in achieving efficient separation and filtration. Meanwhile, its flexibility and practicality need to be improved. Utility Model Content
[0004] The utility model aims to provide a vacuum pump filtering device for a paper towel machine which can be flexibly installed on an existing vacuum pump and can perform efficient debris separation operations, with high filtering effect and strong practicality.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A vacuum pump filtering device for a paper towel machine that is flexible in use comprises a vacuum pump, a support frame is arranged on the outside of the vacuum pump, a separation cylinder is fixedly installed on the upper end of the support frame, the separation cylinder is composed of a cylindrical section and a conical section, an air inlet pipe is fixedly connected to the side surface of the separation cylinder, the outer edge of the air inlet pipe is tangent to the side surface of the separation cylinder, an air outlet pipe is fixedly installed at the middle position of the upper end surface of the separation cylinder, a filter cylinder is installed at one end of the air outlet pipe, the filter cylinder is located inside the separation cylinder and is coaxial with the central axis of the separation cylinder, a collecting tank is installed at the lower end of the separation cylinder, an air guide hose is fixedly installed at the air outlet end of the air outlet pipe, and a flange is installed at one end of the air guide hose.
[0007] By adopting the above technical solution, it can be conveniently installed on the air inlet end of the existing vacuum pump, and during filtering, air mixed with waste paper scraps and dust enters the interior of the separation cylinder, and the mixed gas entering the separation cylinder rotates. At this time, the waste paper scraps and dust can be effectively collected to the middle position, and under the action of gravity, the waste paper scraps and dust fall into the interior of the collection tank, and then the remaining air is filtered by the filter cylinder, which can achieve efficient filtering operation.
[0008] Furthermore, a mounting hole is provided on the side surface of the air inlet pipe, and a first air pressure sensor is fixedly installed inside the mounting hole. A mounting hole is provided on the side surface of the air guide hose near the air outlet end, and a second air pressure sensor is fixedly installed inside the mounting hole.
[0009] By adopting the above technical solution, the pressure difference between the first air pressure sensor and the second air pressure sensor can be used to determine whether the filter cartridge is blocked.
[0010] In summary, the beneficial technical effects of the utility model are:
[0011] 1. The utility model uses a flange to conveniently connect the air guide hose to the air inlet end of the vacuum pump. At this time, the vacuum pump works, so that the external air enters the interior of the separation cylinder from the air inlet pipe. Since the air inlet pipe is tangentially distributed with the side surface of the separation cylinder, the air entering the separation cylinder rotates, which can effectively gather the dust and waste paper scraps in the air to the middle position, and fall into the collection tank below under the action of gravity. Then the separated air passes through the filter cylinder into the air outlet pipe, and then enters the vacuum pump along the air guide hose. This operation can effectively separate the paper scraps and dust in the air, reduce the probability of clogging the filter cylinder, and improve the filtering effect. At the same time, the device can be flexibly and conveniently installed on the existing vacuum pump equipment;
[0012] 2. The utility model can use the first air pressure sensor to detect the air pressure value at the air inlet end of the air inlet pipe, and use the second air pressure sensor to detect the air pressure value at the air outlet end of the air guide hose. When the pressure difference between the two is large, the surface filter cartridge is seriously clogged and the filter cartridge needs to be cleaned. This structure enables the device to have an internal blockage self-detection function. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The method of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0017] Reference Figure 1 , Figure 2, a vacuum pump filtering device for a tissue machine with flexible use, comprises a vacuum pump 1, a support frame 2 is arranged outside the vacuum pump 1, a separation cylinder 3 is fixedly mounted on the upper end of the support frame 2, the separation cylinder 3 is composed of a cylindrical section and a conical section, an air inlet pipe 5 is fixedly connected to the side surface of the separation cylinder 3, the outer edge of the air inlet pipe 5 is tangentially distributed with the side surface of the separation cylinder 3, an air outlet pipe 10 is fixedly mounted at the middle position of the upper end surface of the separation cylinder 3, a filter cylinder 9 is mounted at one end of the air outlet pipe 10, the filter cylinder 9 is located inside the separation cylinder 3 and is coaxial with the central axis of the separation cylinder 3, a collecting tank 4 is mounted at the lower end of the separation cylinder 3, an air outlet end of the air outlet pipe 10 is fixedly mounted with an air guide hose 7, and a flange is mounted at one end of the air guide hose 7, which can be used to filter the air. The air guide hose 7 is conveniently connected to the air inlet end of the vacuum pump 1 by using a flange. At this time, the vacuum pump 1 is working, so that the external air enters the interior of the separation cylinder 3 from the air inlet pipe 5. Since the air inlet pipe 5 is tangentially distributed to the side surface of the separation cylinder 3, the air entering the interior of the separation cylinder 3 rotates, which can effectively gather the dust and waste paper scraps in the air to the middle position, and fall into the collection tank 4 below under the action of gravity. Then the separated air passes through the filter cylinder 9 into the air outlet pipe 10, and then enters the vacuum pump 1 along the air guide hose 7. This operation can effectively separate the paper scraps and dust in the air, reduce the probability of blockage of the filter cylinder 9, and improve the filtering effect. At the same time, the device can be flexibly and conveniently installed on the existing vacuum pump 1 equipment.
[0018] Reference Figure 1 A mounting hole is provided on the side surface of the air inlet pipe 5, and a first air pressure sensor 6 (BMP280) is fixedly installed inside the mounting hole. A mounting hole is provided on the side surface of the air guide hose 7 near the air outlet end, and a second air pressure sensor 8 (BMP280) is fixedly installed inside the mounting hole. The first air pressure sensor 6 can be used to detect the air pressure value at the air inlet end of the air inlet pipe 5, and the second air pressure sensor 8 can be used to detect the air pressure value at the air outlet end of the air guide hose 7. When the pressure difference between the two is large, the surface filter cartridge 9 is seriously clogged and the filter cartridge 9 needs to be cleaned. This structure enables the device to have an internal blockage self-detection function.
[0019] Working principle: When in use, the device is first moved to one side of the vacuum pump 1, and then the flange is used to conveniently connect the air guide hose 7 to the air inlet end of the vacuum pump 1. At this time, the vacuum pump 1 works, so that external air enters the interior of the separation cylinder 3 from the air inlet pipe 5. Since the air inlet pipe 5 is tangentially distributed to the side surface of the separation cylinder 3, the air entering the interior of the separation cylinder 3 rotates, which can effectively gather dust and waste paper scraps in the air to the middle position, and fall into the collection tank 4 below under the action of gravity. Then the separated air passes through the filter cylinder 9 into the air outlet pipe 10, and then enters the vacuum pump 1 along the air guide hose 7. During the operation of the device, the first air pressure sensor 6 can be used to detect the air pressure value at the air inlet end of the air inlet pipe 5, and the second air pressure sensor 8 can be used to detect the air pressure value at the air outlet end of the air guide hose 7. When the pressure difference between the two is large, the surface filter cylinder 9 is seriously blocked and the filter cylinder 9 needs to be cleaned.
