A gas-liquid separator is installed next to the vacuum protection tank, and a liquid collection tank is installed between the Röch pump and the vacuum pump. This allows materials to settle in the gas-liquid separator and the liquid collection tank, preventing materials from being drawn away by the vacuum pump and wasting them. It also prevents pipe blockage, increases working efficiency, and reduces environmental pollution, meeting environmental protection requirements. However, this patent still has the following problems in actual use:

[0004] The vacuum unit in this workshop has a gas-liquid separator installed next to the vacuum protection tank, and a slurry tank installed between the Röch pump and the vacuum pump. This allows materials to settle in the gas-liquid separator and slurry tank, preventing them from being drawn away by the vacuum pump and wasting material, and also preventing pipe blockage.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This vacuum unit can filter insoluble impurities through a filter screen. When the filter screen becomes clogged, gravity will cause the first connecting bracket and the lifting sliding sleeve to descend. When the telescopic starter is in the extended state, the cleaning motor is activated to drive the cleaning rotating rod to rotate, which in turn causes the connecting spring to drive the spiral cleaning blades to rotate, thus cleaning the impurities on the filter screen. Under the damping effect of the damping roller, the amplitude of spring vibration is reduced, thereby achieving a shock absorption effect, reducing the vibration frequency of the vacuum unit, and protecting the vacuum unit. The specific details are as follows:

[0022] 1. By setting up a purification mechanism, a vacuum pump can be driven by a drive motor to generate suction and create a vacuum. When the equipment to be vacuumed contains moisture, the moisture and air enter the first purification chamber together through the inlet pipe. Since air is lighter than water, it will float at the top of the inlet pipe and be drawn out of the first purification chamber through the annular suction hood and guide pipe. The moisture will fall into the purification cylinder. Because the water contains some insoluble impurities and soluble pollutants, the filter screen can filter out the insoluble impurities. When the filter screen becomes clogged, gravity will cause the first connecting bracket and the lifting sliding sleeve to descend. When the telescopic starter is in the extended state, the cleaning motor is activated, which drives the cleaning rotating rod to rotate, causing the connecting spring to drive the spiral cleaning blades to rotate, thus cleaning the impurities on the filter screen and causing them to fall onto the collection tray at the bottom. The collection tray can be cleaned through the cleaning chamber door. The moisture that has passed through the filter screen can fall into the purification hopper through the guide cylinder. The purification chamber can be filled with a certain amount of purification agent to purify soluble pollutants in the water. The purification agent can be formulated according to the pollutants contained in the vacuum equipment to be vacuumed. The treated water can be discharged through the discharge valve. When the air drawn in contains impurities and harmful gases, it undergoes multiple purification treatments through the purification screen plate inside the second purification chamber. The sealing plate can be opened by the first handle, and the purification screen plate can be removed from the second purification chamber by pulling the pull plate. Under the action of the torsion spring hinge, the sealing plate can be closed, so that the purification screen plate can be cleaned or replaced without stopping the machine. The filter plate can perform secondary filtration on the drawn-in gas. When the filter plate needs to be replaced, first pull up the sealing ring and start the switching motor to drive the rotating worm gear to rotate. Utilizing the meshing connection between the rotating worm gear and the switching turbine, the switching turbine can drive the filter plate to rotate. Through the elastic force of the compression spring, the sealing ring and the filter plate are tightly fitted, improving the sealing performance between the filter plate and the outlet pipe.

[0023] 2. By setting up a movable buffer mechanism, when the entire vacuum unit needs to be moved, the movable bracket can be moved arbitrarily using the casters and push handle to move the vacuum unit to the designated position. By rotating the support bolts, the support pad is raised and lowered. The support bolts and support pad lift one end of the movable bracket. By pulling the unlock bracket, and with the locking sliding rod and locking sliding sleeve slidingly connected, the locking block separates from the engaging gear. Rotating the engaging gear causes the second rotating bracket to rotate 90 degrees, rotating the buffer bracket to a vertical position. The movable bracket is fixed with fixing pins. The damping spring provides a buffering effect. When the vacuum unit is working, it will generate a certain amount of vibration. The elastic force of the buffer spring provides a buffering effect. At the same time, the elastic force of the limit spring allows the rotation of the limit bracket to be achieved. The damping effect inside the damping roller reduces the amplitude of the spring vibration, thereby achieving a shock absorption effect, reducing the vibration frequency of the vacuum unit, and protecting the vacuum unit.

When the equipment to be vacuumed contains a certain amount of moisture, the moisture and air enter the first purification box 104 together through the air inlet pipe 106. Since air is lighter than water, the air will be suspended at the top of the air inlet pipe 106 and drawn out of the first purification box 104 through the annular suction hood 123 and the air guide pipe 124. The moisture will fall into the purification cylinder 108. Since the water contains a certain amount of insoluble impurities and soluble pollutants, the insoluble impurities can be filtered through the filter screen plate 113.

When the filter screen 113 becomes clogged, the first connecting bracket 112 and the lifting sliding sleeve 110 will descend under the action of gravity. When the telescopic starter 119 is in the extended state, the cleaning motor 116 is started to drive the cleaning rotating rod 117 to rotate, so that the connecting spring 118 drives the spiral cleaning blade 120 to rotate, which can clean the impurities on the filter screen 113 and make the impurities fall into the collection tray 125 at the bottom. The collection tray 125 can be cleaned through the cleaning box door 122.

The sealing plate 133 can be opened by the first handle 134, and the purification screen 137 can be taken out from the second purification box 130 by pulling the pull plate 135. Under the action of the torsion spring hinge 132, the sealing plate 133 can be closed, so that the purification screen 137 can be cleaned or replaced without stopping the machine.

Utilizing the meshing connection between the rotating worm gear 144 and the switching turbine 145, the switching turbine 145 can drive the filter discs 146 to rotate. Through the elastic force of the compression spring 140, the sealing ring 141 and the filter discs 146 are tightly fitted, improving the sealing performance between the filter discs 146 and the air outlet pipe 138.

[0041] Please see Figure 1 , Figures 9-11 The movable buffer mechanism 2 includes a movable bracket 201, which is fixedly installed at the bottom of the mounting bracket 101. A push handle 202 is rotatably connected to one side of the top of the movable bracket 201. Support bolts 203 are threadedly connected to both sides of the inside of the movable bracket 201. A support pad 204 is rotatably connected to the bottom of the support bolts 203. Locking sliding rods 205 are fixedly installed around the movable bracket 201.

The bottom of the second rotating bracket 211 is symmetrically equipped with casters 212. Several buffer brackets 213 are fixedly installed on one side of the second rotating bracket 211. When the entire vacuum unit needs to be moved, the moving bracket 201 can be moved arbitrarily by means of the casters 212 and the push handle 202 to move the vacuum unit to the designated position. By rotating the support bolt 203, the support pad 204 is driven to rise and fall. The support bolt 203 and the support pad 204 lift one end of the moving bracket 201. By pulling the unlocking bracket 209 and under the action of the locking sliding rod 205 and the locking sliding sleeve 206 sliding connection, the locking block 208 is separated from the engaging gear 210. The engaging gear 210 is rotated so that the engaging gear 210 drives the second rotating bracket 211 to rotate 90 degrees, and the buffer bracket 213 is rotated to the vertical position.

[0042] Please see Figures 10-11The buffer bracket 213 has buffer sliding rods 214 symmetrically installed inside, and a buffer sliding sleeve 215 is slidably connected to the outer side of the buffer sliding rod 214.

A second connecting bracket 225 is fixedly installed between the buffer brackets 213. The moving bracket 201 is fixed by the fixing nail 224. The damping spring 223 can realize the buffering effect of the moving bracket 201. When the vacuum unit is working, it will generate a certain vibration. The buffering effect can be achieved by the elastic force of the buffer spring 216. At the same time, under the elastic force of the limit spring 220, the limit bracket 217 can be rotated. Under the damping effect inside the damping roller 222, the amplitude of the spring vibration is reduced, thereby achieving the effect of shock absorption, reducing the vibration frequency of the vacuum unit, and achieving the effect of protecting the vacuum unit.

[0043] Working principle: Before using this type of vacuum unit, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 11As shown, firstly, when the entire vacuum unit needs to be moved, the movable bracket 201 can be moved arbitrarily using the casters 212 and the push handle 202 to move the vacuum unit to the designated position. Then, by rotating the support bolt 203, the support pad 204 is raised and lowered. The support bolt 203 and the support pad 204 lift one end of the movable bracket 201. By pulling the unlocking bracket 209, and with the locking sliding rod 205 and the locking sliding sleeve 206 sliding together, the locking block 208 separates from the engaging gear 210. Rotating the engaging gear 210 then drives the second rotating bracket 201. 11. Rotate 90 degrees to bring the buffer bracket 213 to a vertical position. Fix the movable bracket 201 with the fixing pin 224. The damping spring 223 can buffer the movable bracket 201. When the vacuum unit is working, it will generate a certain vibration. The elastic force of the buffer spring 216 can achieve the buffering effect. At the same time, under the elastic force of the limit spring 220, the limit bracket 217 can be rotated. Under the damping effect inside the damping roller 222, the amplitude of the spring vibration is reduced, thereby achieving the shock absorption effect, reducing the vibration frequency of the vacuum unit, and achieving the effect of protecting the vacuum unit.

[0044] Secondly, the vacuum pump 103 is driven by the drive motor 102 to generate a certain suction force for vacuuming. When the equipment to be vacuumed contains a certain amount of moisture, the moisture and air enter the first purification chamber 104 together through the air inlet pipe 106. Since air is lighter than water, the air will float at the top of the air inlet pipe 106 and be drawn out of the first purification chamber 104 through the annular suction hood 123 and the air guide pipe 124. The moisture will fall into the purification cylinder 108. Since the water contains certain insoluble impurities and soluble pollutants, the insoluble impurities can be filtered out by the filter screen 113. When the filter screen 113 becomes clogged, the first connecting bracket 112 will be driven by gravity. As the lifting sliding sleeve 110 descends, the extension starter 119 is in the extended state, which starts the cleaning motor 116 to drive the cleaning rotating rod 117 to rotate, causing the connecting spring 118 to drive the spiral cleaning blade 120 to rotate, thus cleaning the impurities on the filter screen 113 and causing the impurities to fall into the collection tray 125 at the bottom. The collection tray 125 can be cleaned through the cleaning box door 122. The water passing through the filter screen 113 can fall into the purification hopper 127 through the guide cylinder 126. A certain amount of purification agent can be put into the purification hopper 127 to purify the soluble pollutants in the water. The purification agent can be prepared according to the pollutants contained in the vacuum equipment to be vacuumed. The treated water can be discharged through the discharge valve 128.

[0045] Finally, when the drawn-in air contains impurities and harmful gases, it undergoes multiple purification processes through the purification screen 137 inside the second purification chamber 130. The sealing plate 133 can be opened using the first handle 134, and the purification screen 137 can be removed from the second purification chamber 130 by pulling the pull plate 135. Under the action of the torsion spring hinge 132, the sealing plate 133 can be closed, allowing for cleaning or replacement of the purification screen 137 without shutting down the machine. The filter disc 146 can... The system can perform secondary filtration on the drawn-in gas.
