[0004] The workshop vacuum unit equipment has a gas-liquid separator installed beside the vacuum protection barrel, and a liquid accumulation barrel installed between the roots pump and the vacuum pump, enabling the material to precipitate in the gas-liquid separator and the liquid accumulation barrel, avoiding the material being pumped away by the vacuum pump, resulting in material waste, and at the same time avoiding pipeline blockage. Although the gas-liquid separation and material precipitation are carried out by setting the vacuum protection barrel and the gas-liquid separator, when the vacuum unit is evacuating, due to the presence of a certain amount of air and moisture in the equipment, some of the air contains harmful gases, and at the same time, the moisture contains certain impurities and pollutants, and the extracted air or moisture cannot be treated, which not only causes the phenomenon of vacuum unit blockage, but also the discharge of pollutants will cause environmental pollution.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: For a vacuum unit, the filter screen plate can filter insoluble impurities. When the filter screen plate is blocked, it will drive the first connecting bracket and the lifting sliding sleeve to descend under the action of gravity. When the telescopic actuator is in the extended state, the cleaning motor is started to drive the cleaning rotating rod to rotate, so that the connecting spring drives the spiral cleaning blade to rotate, which can clean the impurities on the filter screen plate. Under the action of the damping inside the damping roller, the amplitude of the spring vibration is reduced, thereby achieving the damping effect and reducing the vibration frequency of the vacuum unit, achieving the effect of protecting the vacuum unit. The specific content is as follows:

[0022] 1. By setting up a purification mechanism, not only can the driving motor be used to drive the vacuum pump to work, so that the vacuum pump generates a certain suction force to carry out vacuum pumping. When the equipment to be vacuumed contains a certain amount of moisture, the moisture and air enter the first purification tank together through the air inlet pipe. Since air is lighter than water, the air will float on the top of the air inlet pipe and be evacuated from the first purification tank through the annular suction hood and the air guide pipe. The moisture will fall into the purification cylinder. Since the water will contain a certain amount of insoluble impurities and soluble pollutants, the filter screen plate can filter the insoluble impurities. When the filter screen plate is blocked, it will drive the first connecting bracket and the lifting sliding sleeve to descend under the action of gravity. When the telescopic actuator is in the extended state, the cleaning motor is started to drive the cleaning rotating rod to rotate, so that the connecting spring drives the spiral cleaning blade to rotate, which can clean the impurities on the filter screen plate, causing the impurities to fall onto the collection tray at the bottom. The collection tray can be cleaned through the cleaning chamber door. The water passing through the filter screen plate can fall into the purification hopper through the guide cylinder. A certain amount of purification agent can be placed in the purification hopper to purify the soluble pollutants in the water. The purification agent can be formulated according to the pollutants contained in the equipment to be vacuumed. The treated water can be discharged through the discharge valve. When the sucked air contains impurities and harmful gases, multiple purification treatments are carried out through the purification screen plate inside the second purification tank. The sealing plate can be opened through the first handle, and the purification screen plate can be taken out of the second purification tank 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 sucked gas can be secondarily filtered through the filter disc. When the filter disc needs to be replaced, first lift the sealing ring upward and start the switching motor to drive the rotating worm to rotate. By using the meshing connection between the rotating worm and the switching turbine, the switching turbine can be driven to drive the filter disc to rotate. Under the elastic action of the compression spring, the sealing ring fits tightly with the filter disc, improving the sealing performance between the filter disc and the air outlet pipe;

[0023] 2. When it is necessary to move the entire vacuum unit, the movable buffer mechanism can be set to achieve arbitrary movement of the movable bracket through the universal wheels and the pushing handle, and move the vacuum unit to the designated position. By rotating the support bolt to drive the support pad to move up and down, one end of the movable bracket is lifted by the support bolt and the support pad. By pulling the unlocking bracket and under the action of the sliding connection between the locking sliding rod and the locking sliding sleeve, the locking block is separated from the engaging gear, and the engaging gear is rotated to drive the second rotating bracket to rotate 90 degrees, turning the buffer bracket to the vertical state. The movable bracket is fixed by the fixing nails. The damping spring can achieve the buffering effect of the movable bracket. When the vacuum unit is working, certain vibrations will be generated. With the elastic force of the buffer spring, the buffering effect can be achieved. At the same time, under the elastic force of the limit spring, the rotation of the limit bracket can be realized, and under the action of the damping inside the damping roller, the amplitude of the spring vibration can be reduced, thus achieving the damping effect and reducing the vibration frequency of the vacuum unit to achieve the effect of protecting the vacuum unit.

When the equipment to be vacuumed contains a certain amount of moisture, the moisture and air enter the first purification tank 104 together through the air inlet pipe 106. Since air is lighter than water, the air will suspend at the top of the air inlet pipe 106 and is evacuated from the first purification tank 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 will contain a certain amount of insoluble impurities and soluble pollutants, the insoluble impurities can be filtered through the filter screen plate 113.

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 plate 113, and make the impurities fall onto the collection tray 125 at the bottom.

The water on the filter mesh plate 113 can fall into the purification hopper 127 through the material guiding cylinder 126. A certain amount of purification agent can be placed in 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 equipment to be evacuated. The treated water can be discharged through the discharge valve 128. When the drawn air contains impurities and harmful gases, multiple purification treatments are carried out through the purification mesh plate 137 inside the second purification tank 130. The sealing plate 133 can be opened through the first handle 134, and the purification mesh plate 137 can be taken out of the second purification tank 130 by pulling the pull-out plate 135. Under the action of the torsion spring hinge 132, the sealing of the sealing plate 133 can be realized, so that the cleaning or replacement of the purification mesh plate 137 can be carried out without shutting down the machine.

By using the meshing connection characteristic between the rotating worm 144 and the switching turbine 145, the switching turbine 145 can be driven to drive the filter discs 146 to rotate. Through the elastic force of the compression spring 140, the sealing ring 141 is closely attached to the filter discs 146, improving the sealing performance between the filter discs 146 and the air outlet pipe 138.

[0041] Please refer toFigure 1 , Figures 9-11 , the moving buffer mechanism 2 includes a moving bracket 201. The moving bracket 201 is fixedly installed at the bottom of the mounting bracket 101. One side of the top of the moving bracket 201 is rotatably connected to a pushing handle 202. Support bolts 203 are threadedly connected to both sides inside the moving bracket 201.

Universal wheels 212 are symmetrically installed at the bottom of the second rotating bracket 211. A number of 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 through the universal wheels 212 and the pushing handle 202, and the vacuum unit is moved to a specified position. By rotating the support bolts 203 to drive the support pads 204 to move up and down, one end of the moving bracket 201 is lifted by the support bolts 203 and the support pads 204. By pulling the unlocking bracket 209 and under the action of the sliding connection between the locking sliding rod 205 and the locking sliding sleeve 206, the locking block 208 is separated from the engaging gear 210, and 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 a vertical state.

[0042] Please refer to Figures 10-11, buffer sliding rods 214 are symmetrically installed vertically inside the buffer bracket 213.

The moving bracket 201 is fixed by using the fixing nail 224. The buffer effect of the moving bracket 201 can be achieved by using the damping spring 223. When the vacuum unit works, certain vibrations will be generated. By the elastic force of the buffer spring 216, the buffering effect can be achieved. At the same time, under the elastic force of the limit spring 220, the rotation of the limit bracket 217 can be achieved. And under the action of the damping inside the damping roller 222, the amplitude of the spring vibration can be reduced, so as to achieve the damping effect and reduce the vibration frequency of the vacuum unit, achieving the effect of protecting the vacuum unit.

[0043] Working principle: Before using this vacuum unit, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, when the entire vacuum unit needs to be moved, the movable support 201 can be moved arbitrarily through the universal wheels 212 and the push handle 202, and the vacuum unit is moved to the designated position. By rotating the support bolt 203, the support pad 204 is driven to move up and down. One end of the movable support 201 is lifted by the support bolt 203 and the support pad 204. By pulling the unlocking bracket 209 and under the action of the sliding connection between the locking sliding rod 205 and the locking sliding sleeve 206, the locking block 208 is separated from the engaging gear 210, and the engaging gear 210 is rotated, so that the engaging gear 210 drives the second rotating support 211 to rotate by 90 degrees, and the buffer support 213 is rotated to the vertical state. The movable support 201 is fixed by the fixing nail 224. The damping spring 223 can achieve the buffering effect of the movable support 201. When the vacuum unit works, certain vibrations will be generated. By the elastic force of the buffer spring 216, the buffering effect can be achieved. At the same time, under the elastic force of the limiting spring 220, the limiting support 217 can be rotated, and under the action of the damping inside the damping roller 222, the amplitude of the spring vibration is reduced, so as to achieve the damping effect, reduce the vibration frequency of the vacuum unit, and achieve the effect of protecting the vacuum unit.

[0044] Secondly, the driving motor 102 is used to drive the vacuum pump 103 to work, so that the vacuum pump 103 generates a certain suction force to evacuate the air. When the equipment to be evacuated contains a certain amount of moisture, the moisture and air enter the first purification tank 104 together through the air inlet pipe 106. Since air is lighter than water, the air will float on the top of the air inlet pipe 106 and is evacuated from the first purification tank 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 will contain a certain amount of insoluble impurities and soluble pollutants, the insoluble impurities can be filtered by the filter mesh plate 113. When the filter mesh plate 113 is blocked, it will drive the first connecting bracket 112 and the lifting sliding sleeve 110 to 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, and the impurities on the filter mesh plate 113 can be cleaned, so that the impurities fall onto the bottom collection tray 125. The collection tray 125 can be cleaned through the cleaning box door 122. The water passing through the filter mesh plate 113 can fall into the purification hopper 127 through the guide cylinder 126. A certain amount of purification agent can be placed in 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 equipment to be evacuated. The treated water can be discharged through the discharge valve 128.

[0045] Finally, when the drawn air contains impurities and harmful gases, multiple purification treatments are performed through the purification mesh plate 137 inside the second purification box 130. The sealing plate 133 can be opened through the first handle 134, and the purification mesh plate 137 can be taken out of the second purification box 130 by pulling the drawer plate 135. Under the action of the torsion spring hinge 132, the sealing plate 133 can be closed, so that the purification mesh plate 137 can be cleaned or replaced without shutting down the machine. The drawn gas can be secondarily filtered through the filter disc 146. When the filter disc 146 needs to be replaced, first lift the sealing ring 141 upward, and start the switching motor 143 to drive the rotating worm 144 to rotate. By utilizing the meshing connection between the rotating worm 144 and the switching turbine 145, the switching turbine 145 can drive the filter disc 146 to rotate. Through the elastic force of the compression spring 140, the sealing ring 141 is closely attached to the filter disc 146, improving the sealing performance between the filter disc 146 and the air outlet pipe 138.
