Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum pumps, in particular to a sanitary vacuum pump dust filtering device. Background Art

[0002] Food and pharmaceutical processing involves negative pressure powder conveying, powered by a dry vacuum pump. To protect the vacuum pump from foreign matter like dust particles, which could damage its seals and components, dust filters are often used. Common dust filtration devices are filter elements. Dust accumulates over time, gradually decreasing filtration efficiency. Therefore, regular replacement is necessary to ensure effective filtration. Dust filters are consumable, and replacement requires production suspension. This filter wear and tear increases production costs. Utility Model Content

[0004] A further technical solution is that: there are no less than three dust gas connection ports, and all the dust gas connection ports are evenly distributed on the side wall of the dust collection barrel, thereby avoiding serious blockage on one side of the filter bag.

[0005] A further technical solution is: the sanitary vacuum pump dust filtering device also includes a control system, and electronic pressure gauges are respectively installed in the dust collection barrel and the filtered air barrel. The pressure gauges can be used to judge the decline in the filtering capacity of the filter bag. The output ends of the two electronic pressure gauges are electrically connected to the input and output ends of the control system, and the output end of the control system is electrically connected to the vibrator. When the filtering capacity of the filter bag drops to a specified range value, the control system sends a command to turn on the vibrator.

[0006] A further technical solution is that the filter bag and the filtered air barrel are detachably connected via a throat hoop.

[0007] A further technical solution is that the lower part of the dust collection barrel is provided with a dust cleaning door.

[0008] A further technical solution is: the bottom of the dust collection barrel is filled with water, and a water inlet and a water outlet are provided at the lower part of the dust collection barrel.

It also features a simple structure and minimal manufacturing complexity. While the vacuum pump is operating continuously, dust can be readily removed from the filter bag, ensuring efficient filtration. The present invention is suitable for installation in front of a vacuum pump for conveying food or pharmaceutical powders. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] Example 1: Figure 1-Figure 2 The sanitary vacuum pump dust filtration device shown includes an acrylic dust cleaning door 1, a dust collection bucket 2, a filter bag 3, a filtered air bucket 4, a pneumatic vibrator 5, a vacuum pump connection port 6, a dust gas connection port 7, an electronic pressure gauge 8 and a control system 9.

[0016] The filtered air bucket 4 is located above the dust collection bucket 2, and the two are fastened together via fasteners. A filter bag 3 is located within the dust collection bucket 2, attached to the bottom of the filtered air bucket 4. A vibrator 5 is mounted above the filtered air bucket 4, and its vibrating component is connected to the filter bag 3, transmitting vibrations to the filter bag 3, thereby removing dust from the filter bag 3. A dust gas connection port 7 is connected to the side wall of the dust collection bucket 2, and a vacuum pump connection port 6 is connected to the side wall of the filtered air bucket 4.

[0017] The vibrator 5 is a vibrating cylinder, the piston of which rises and falls according to a set frequency, causing the dust on the filter bag 3 to fall into the dust collection barrel 2.

[0018] The utility model can be connected to the front of the vacuum pump in a sanitary and quick manner, thereby preventing the vacuum pump from being invaded by foreign matter such as dust particles.

[0019] There are no less than three dust gas connection ports 7 , and all the dust gas connection ports 7 are evenly distributed on the side wall of the dust collecting barrel 2 , thereby preventing the filter bag 3 from being blocked on one side.

[0020] The sanitary vacuum pump dust filtration device also includes a control system 9. Electronic pressure gauges 8 are installed in the dust collection bucket 2 and the filtered air bucket 4, respectively. The values of the two electronic pressure gauges 8 can be used to determine the decline in the filtration capacity of the filter bag 3. The output ends of the two electronic pressure gauges 8 are electrically connected to the input and output ends of the control system 9. The output end of the control system 9 is electrically connected to the vibrator 5. When the filtration capacity of the filter bag 3 drops to a specified range, the control system 9 sends a command to turn on the vibrator 5. The control program used in the control system 9 of the utility model is the most commonly used program in the prior art. That is, when the electronic pressure gauge 8 triggers the set value of the control system 9, the control sends a command to instruct the vibrator 5 to operate.

[0021] The filter bag 3 and the filtered air barrel 4 are detachably connected via a throat hoop, making them more convenient to disassemble and clean.

[0022] The lower part of the dust collecting barrel 2 is provided with a dust cleaning door 1. When the amount of dust collected is excessive, the dust cleaning door 1 is opened for cleaning.

[0023] Example 2 differs from Example 1 in that this example does not include a dust cleaning door 1. Instead, a water inlet 10 and a water outlet 11 are provided at the bottom of the dust collection bucket 2. Water is filled into the bottom of the dust collection bucket 2 through the water inlet 10, and dust falls into the water, thereby preventing secondary dust from flying. When the dust concentration in the water is high, the water is discharged through the water outlet 11 and clean water is added again through the water inlet 10, allowing dust cleaning to be performed online without stopping the vacuum pump.

[0024] In summary, the utility model has a simple structure, low manufacturing difficulty, and can clean the filter bag 3 dust at any time when the vacuum pump is working continuously, thereby ensuring the filtration efficiency. The utility model is suitable for setting before the vacuum pump for conveying food and medicine powders.
