Description

Technical Field

[0001] The invention relates to the technical field of impurity processing devices for vacuum pumps, in particular to an impurity separation and processing mechanism for a sliding valve vacuum pump. Background Art

[0002] The impurity separation and processing mechanism is an indispensable device in the impurity separation work of the sliding valve vacuum pump. It can effectively remove impurities such as solid particles mixed in the pumped gas and prevent these impurities from accumulating in the pump, thereby maintaining the normal operation performance of the vacuum pump, ensuring its pumping efficiency and vacuum degree, and avoiding impurities from causing wear and corrosion to the internal components of the pump, such as the sliding valve and cylinder body, thereby reducing the probability of failure, significantly extending the service life of the vacuum pump, and helping to maintain the purity of the entire vacuum system, preventing impurities from entering subsequent process links and having an adverse effect on related production or experimental processes, and separating impurities in time so that the vacuum pump can work continuously and stably, reducing operating fluctuations or fault shutdowns caused by impurities.

[0003] The Chinese patent with the announcement number CN112524028B discloses an impurity separation and processing device for a sliding valve vacuum pump. The impurity separation and processing device comprises a sliding valve vacuum pump, an air inlet of the sliding valve vacuum pump is provided with an air suction pipe, a cleaning mechanism is provided in the middle of the air suction pipe, a one-way valve is provided at the front end of the air suction pipe, the cleaning mechanism comprises a suction pump, the suction pump is arranged behind the one-way valve, a suction blade is provided inside the suction pump, a cleaning liquid pipe is provided above the suction pump, a cleaning liquid recovery tank is provided at the end of the cleaning liquid pipe, a separation cylinder is connected to a pipe on one side of the top of the cleaning liquid recovery tank, an exhaust pipe is provided on one side of the top of the separation cylinder, the exhaust pipe is connected to the exhaust port pipe of the sliding valve vacuum pump, and a pipe on one side of the top of the cleaning liquid recovery tank is connected to the separation cylinder. The present invention has the characteristics of strong practicability and can clean the inner cavity during the operation of the sliding valve vacuum pump.

[0004] The existing impurity separation and processing mechanism can clean the impurities entering the slide valve pump and separate them after cleaning. However, if large particles of impurities in the gas enter the slide valve pump and are cleaned again, the slide valve pump will drive the large particles of impurities to move at high speed through the cleaning fluid. Since the large particles of impurities will cause wear, impact and cracking to the internal components of the pump, such as the slide valve and cylinder body, when moving at high speed, the probability of failure is increased and the service life is reduced. At the same time, if the filter is blocked, the operation must be stopped for maintenance, which greatly reduces the work efficiency.

[0005] Therefore, a sliding valve vacuum pump impurity separation and processing mechanism is needed to solve the problem that if large particles of impurities in the gas enter the sliding valve pump and cause damage, the service life will be reduced, and the filter screen will be blocked and the operation must be stopped, resulting in low work efficiency.

[0021] The beneficial effects of the present invention are as follows:

[0022] (1) The impurity separation and processing mechanism of the sliding valve vacuum pump described in the present invention is that when impurities accumulate and increase on the right side of the main filter, the filter moves to the side close to the intake pipe, and the auxiliary baffle moves into the inner side of the square groove to release the restriction on the auxiliary filter. When the left side of the filter contacts the left inner wall of the main slide, the main baffle moves to the inner side of the main airway and completely closes the main airway. At this time, the auxiliary baffle moves completely into the inner side of the square groove, and the filter completely releases the closure of the auxiliary airway. At this time, the auxiliary filter is used to filter impurities. When impurities accumulate and increase on the right side of the auxiliary filter, the auxiliary filter transmission plate moves to the side close to the intake pipe, and the main slide contacts the inner side of the main slide. The baffle moves into the inner side of the groove to release the restriction on the main filter. When the spring on the left side of the auxiliary filter plate shrinks to the limit, the main baffle moves completely into the inner side of the groove to release the blockage of the main airway. The filter moves to the right side of the filter and fits against the right inner wall of the main slide. During this process, the auxiliary baffle moves into the auxiliary slide to completely block the auxiliary airway. Under the action of the spring, the auxiliary filter plate drives the auxiliary filter to move to the right side of the auxiliary filter and fits against the left side of the auxiliary baffle, thereby separating large particles of impurities when the slide valve pump is working, avoiding large particles entering the inside of the slide valve pump and causing impact and damage to the slide valve pump, thereby greatly improving the service life of the slide valve pump.

[0023] (2) The impurity separation and processing mechanism of the sliding valve vacuum pump described in the present invention, when the left side of the filter contacts the left inner wall of the main slide, the two cylinders are controlled to contract to drive the long plate to release the blockage of the main water inlet, and the cleaning liquid cleans the main filter under the action of the water pump and drives the impurities to the inside of the recovery barrel and is discharged through the valve on the back of the recovery barrel. After the discharged cleaning liquid is free of impurities, the two cylinders are controlled to extend to drive the long plate to re-close the secondary water inlet, so as to complete the cleaning of the main filter and enable the main filter to be reused. When the right side of the secondary filter fits with the left side of the secondary baffle, the staff controls another cylinder to contract to drive the short plate to release the blockage of the secondary water inlet, and the cleaning liquid cleans the secondary filter under the action of the water pump and drives the impurities to the inside of the recovery barrel and is discharged through the valve on the back of the recovery barrel. When the discharged cleaning liquid is free of impurities, the other cylinder is controlled to extend to drive the short plate to re-close the secondary water inlet, so as to complete the cleaning of the secondary filter and enable the secondary filter to be reused.

[0024] (3) Based on the beneficial effects (1) and (2), the impurity separation and processing mechanism of the sliding valve vacuum pump described in the present invention can not only prevent large particles of impurities from entering the sliding valve pump when the sliding valve pump is working, but also clean the main filter screen and the auxiliary filter screen, thereby making the main filter channel and the auxiliary filter channel reusable, and realizing the rotation of the main filter channel and the auxiliary filter channel, thereby increasing the service life of the sliding valve pump while improving the work efficiency, and recovering impurities while avoiding environmental pollution.

[0042] Example:

[0043] like Figure 1 As shown in FIG. 14, an embodiment of the present invention provides an impurity separation and processing mechanism of a sliding valve vacuum pump, comprising a sliding valve pump 1, an air inlet pipe 3 is installed on the top of the sliding valve pump 1, an air outlet 2 is installed on the top of the sliding valve pump 1, a filter box 4 is installed at the other end of the air inlet pipe 3, and an air inlet valve 45 is installed at the other end of the filter box 4, and further comprising:

[0045] The auxiliary filter 6 is arranged inside the filter box 4. When the main filter 5 is blocked, the auxiliary filter plate 62 and the auxiliary filter screen 63 replace the main filter 5 to filter the gas entering the filter box 4.

[0046] A restriction assembly 7 is disposed inside the main filter channel 5 and is configured to seal the main filter channel 5;

[0047] The second restriction component 9 is disposed inside the secondary filter channel 6 and is configured to seal the secondary filter channel 6;

[0048] The transmission assembly 8 is arranged inside the filter box 4 and is located on a side close to the limiting assembly 1 7 and the limiting assembly 2 9, and is configured to transmit the power of the filter 52 to the limiting assembly 2 9 or transmit the power of the auxiliary filter plate 62 to the limiting assembly 1 7;

[0049] The flushing assembly 10 is disposed on the top of the filter box 4 and is configured to clean the main filter screen 54 and the auxiliary filter screen 63 .

[0050] In this embodiment, before using this device, the staff uses a water pipe to connect the valve on the left side of the water tank 101 to the cleaning liquid line through a water pump, and then connects the recovery pipe to the valve on the back of the recovery barrel 102, connects the air intake valve 45 to the object that requires vacuum operation, and then starts the sliding valve pump 1, which can continuously extract gas from the object.

[0051] Specifically, side grooves 41 are formed on the inner walls of both sides of the filter box 4 , and support blocks 42 are installed inside the two side grooves 41 through springs. A long groove 44 is formed inside the filter box 4 , and a short groove 43 is formed inside the filter box 4 .

[0052] In this embodiment, the side groove 41 can provide a moving space for the support block 42 , and the support block 42 is used to support the main baffle 71 .

[0053] Specifically, the main filter 5 also includes a main air duct 55 that passes through the other end of the filter box 4, and the two support blocks 42 are located on the inner side of the main air duct 55. The main air duct 55 is connected to the intake pipe 3 and the intake valve 45. Two main slides 51 are opened on one side of the main air duct 55. The filter 52 is installed on the inner side of the two main slides 51 through a spring, and the main filter screen 54 is installed inside the side of the filter 52 close to the intake valve 45.

[0054] Specifically, the auxiliary filter 6 also includes a auxiliary air duct 65 opened on one side of the main air duct 55, and an auxiliary slide 61 is opened inside the auxiliary air duct 65. A secondary filter plate 62 is installed on the side of the auxiliary slide 61 close to the intake pipe 3 through a spring, and a secondary filter screen 63 is installed through one side of the auxiliary filter plate 62. A transmission plate 64 is installed on the side of the auxiliary filter plate 62 close to the main air duct 55.

[0055] Specifically, the limiting component 7 also includes a top slot 73 opened in the main airway 55, a main baffle 71 is embedded in the inner side of the slot 73, and the main baffle 71 is located on the top of the two support blocks 42, a groove 72 is opened on one side of the main baffle 71, and a slide rod 74 is placed on the inner side of the groove 72.

[0056] Specifically, the limiting component 2 9 also includes a secondary baffle 92 and a square groove 91 opened at the bottom of the secondary slide 61. The secondary baffle 92 is located on the side of the secondary filter plate 62 close to the intake valve 45. A connecting plate 93 is installed on the side of the secondary baffle 92 close to the main air channel 55.

[0057] Specifically, the transmission assembly 8 also includes a bottom column 81 installed at the bottom of the short slot 43, a threaded rod 83 is installed on the outer side of the bottom column 81 through a bearing, and threads are provided on the outer sides of both ends of the threaded rod 83. A short gear 82 is installed on the outer side of one end of the threaded rod 83 close to the bottom column 81, and the short gear 82 is meshed with the transmission plate 64. A sliding rod 74 is sleeved on the outer side of the threaded rod 83, a top column 84 is installed on the top of the long slot 44, a long gear 85 is installed on the outer side of the top column 84 through a bearing, and the long gear 85 is meshed with the tooth groove 53, a screw rod 86 is installed at the bottom of the long gear 85, and a connecting plate 93 is sleeved on the outer side of the screw rod 86.

[0058] In this embodiment, if the gas contains large particles of impurities, the gas drives the impurities to move to the right side of the main filter 54 under the action of negative pressure, and the main filter 54 blocks the impurities on the inner side of the filter box 4. When the impurities accumulate and increase on the right side of the main filter 54, the main filter 54 drives the filter 52 to move to the side close to the intake pipe 3, and the filter 52 drives the long gear 85 to rotate forward through the tooth groove 53, and the long gear 85 drives the screw rod 86 to rotate forward, and the screw rod 86 drives the auxiliary baffle 92 to move to the inner side of the square groove 91 through the connecting plate 93. When the front and back of the filter 52 squeeze the two support blocks 42 into the inner side of the side groove 41, the main baffle 71 moves to the top of the filter 52. When the left side of the filter 52 contacts the left inner wall of the main slide 51, the main baffle 71 moves to the inner side of the main airway 55 and completely closes the main airway 55. At this time, the auxiliary baffle 92 completely moves into the inner side of the square groove 91, and the filter 52 completely releases the blockage of the auxiliary airway 65. At this time, the auxiliary filter 63 performs impurity filtering;

[0059] When impurities accumulate and increase on the right side of the auxiliary filter 63, the auxiliary filter 63 drives the transmission plate 64 to move to the side close to the intake pipe 3 through the auxiliary filter plate 62, and the transmission plate 64 drives the short gear 82 to rotate forward, and the short gear 82 drives the threaded rod 83 to rotate forward, and the threaded rod 83 drives the main baffle 71 to move into the inside of the groove 72 through the slide rod 74, thereby releasing the restriction on the main filter 54. When the spring on the left side of the auxiliary filter plate 62 contracts to the limit, the main baffle 71 completely moves into the inside of the groove 72, releasing the blockage of the main airway 55, and the filter 52 is moved under the action of the spring. The filter 52 moves downward to the right side of the filter 52 and fits the right inner wall of the main slide 51. During this process, the filter 52 drives the long gear 85 to reverse through the tooth groove 53, and the long gear 85 drives the connecting plate 93 and the auxiliary baffle 92 to move to the inside of the auxiliary slide 61 through the screw rod 86, so as to completely close the auxiliary airway 65. The auxiliary filter plate 62 drives the auxiliary filter screen 63 to move to the right side of the auxiliary filter screen 63 and fit the left side of the auxiliary baffle 92 under the action of the spring. The transmission plate 64 drives the threaded rod 83 to reverse through the short gear 82, and the threaded rod 83 drives the slide rod 74 to move to its original position.

[0060] Therefore, large impurities can be separated when the slide valve pump 1 is working, which prevents large impurities from entering the inside of the slide valve pump 1 and causing impact and damage to the slide valve pump 1, thereby greatly improving the service life of the slide valve pump 1.

[0061] Specifically, the flushing assembly 10 includes a water tank 101 installed on the top of the filter box 4, a recovery bucket 102 installed on the bottom of the filter box 4, a base 103 installed on the side of the water tank 101 close to the filter box 4, and three cylinders 104 installed inside the base 103, wherein a long plate 1051 is installed on the top of the output end of two cylinders 104, and a short plate 105 is installed on the top of the output end of another cylinder 104. The filter box 4 is close to the water tank 101 and connected to the long plate 1051. A main water inlet 108 is opened on the side parallel to 051, and the main water inlet 108 is connected to the inner side of the main baffle 71. A secondary water inlet 106 is opened on the side of the filter box 4 close to the water tank 101 and parallel to the long plate 1051, and the secondary water inlet 106 is connected to the inner side of the secondary filter plate 62. A main water channel 109 is opened at the bottom of the main air channel 55, and a secondary water channel 107 is opened at the bottom of the secondary slide 61. Both the main water channel 109 and the secondary water channel 107 are connected to the inner side of the recovery barrel 102.

[0062] In this embodiment, when the left side of the filter 52 contacts the left inner wall of the main slide 51, the two cylinders 104 are controlled to contract and drive the long plate 1051 to release the blockage of the main water inlet 108. The cleaning liquid, under the action of the water pump, cleans the main filter screen 54 through the main water inlet 108 and drives the impurities to the inside of the recovery barrel 102 through the main water channel 109, and is discharged through the valve on the back of the recovery barrel 102. After the discharged cleaning liquid is free of impurities, the two cylinders 104 are controlled to extend and drive the long plate 1051 to re-close the secondary water inlet 106, thereby completing the cleaning of the main filter screen 54 and enabling the main filter screen 54 to be reused.

[0063] When the right side of the auxiliary filter 63 is in contact with the left side of the auxiliary baffle 92, the staff controls another cylinder 104 to contract and drive the short plate 105 to release the blockage of the auxiliary water inlet 106. The cleaning liquid, under the action of the water pump, cleans the auxiliary filter 63 through the auxiliary water inlet 106 and drives the impurities to the inside of the recovery barrel 102 through the auxiliary water inlet 106, and is discharged through the valve at the back of the recovery barrel 102. When the discharged cleaning liquid is free of impurities, another cylinder 104 is controlled to extend and drive the short plate 105 to re-close the auxiliary water inlet 106, thereby completing the cleaning of the auxiliary filter 63 and enabling the auxiliary filter 63 to be reused.

[0064] To sum up, when the sliding valve pump 1 is working, it can not only prevent large particles of impurities from entering the sliding valve pump 1, but also clean the main filter 54 and the auxiliary filter 63, so that the main filter 5 and the auxiliary filter 6 can be reused, and the rotation of the main filter 5 and the auxiliary filter 6 can be realized, thereby increasing the service life of the sliding valve pump 1 while improving the work efficiency, and recovering impurities while avoiding environmental pollution.

[0065] How it works: Initial state reference Figure 1-14 Before using the device, the staff uses a water pipe to connect the valve on the left side of the water tank 101 to the cleaning liquid line through a water pump, and then connects the recovery pipeline to the valve on the back of the recovery barrel 102, connects the air inlet valve 45 to the object that needs vacuum operation, and then starts the slide valve pump 1, which can continuously extract gas from the object;

[0066] If there are large particles of impurities in the gas, the gas drives the impurities to move to the right side of the main filter 54 under the action of negative pressure, and the main filter 54 blocks the impurities on the inner side of the filter box 4. When the impurities accumulate and increase on the right side of the main filter 54, the main filter 54 drives the filter 52 to move to the side close to the intake pipe 3, and the filter 52 drives the long gear 85 to rotate forward through the tooth groove 53, and the long gear 85 drives the screw rod 86 to rotate forward, and the screw rod 86 drives the auxiliary baffle 92 to move into the inside of the square groove 91 through the connecting plate 93, and the restriction on the auxiliary filter 63 is released. When the front and back of the filter 52 squeeze the two support blocks 42 into the inside of the side groove 41, the main baffle 71 moves to the top of the filter 52, and when the left side of the filter 52 and the left side of the main slide 51 are aligned, the filter 52 is moved to the top of the filter 52. When the inner walls of the two sides are in contact, the main baffle 71 moves to the inside of the main airway 55 and closes the main airway 55. At this time, the auxiliary baffle 92 is completely moved into the inside of the square groove 91, and the filter 52 completely releases the blockage of the auxiliary airway 65. At the same time, the two cylinders 104 are controlled to contract and drive the long plate 1051 to release the blockage of the main water inlet 108. Under the action of the water pump, the cleaning liquid cleans the main filter 54 through the main water inlet 108 and drives the impurities to the inside of the recovery barrel 102 through the main water channel 109, and is discharged through the valve on the back of the recovery barrel 102. After the discharged cleaning liquid is free of impurities, the two cylinders 104 are controlled to extend and drive the long plate 1051 to re-close the auxiliary water inlet 106. At this time, the impurities are filtered by the auxiliary filter 63.

[0067] When impurities accumulate and increase on the right side of the auxiliary filter 63, the auxiliary filter 63 drives the transmission plate 64 to move to the side close to the intake pipe 3 through the auxiliary filter plate 62, and the transmission plate 64 drives the short gear 82 to rotate forward, and the short gear 82 drives the threaded rod 83 to rotate forward, and the threaded rod 83 drives the main baffle plate 71 to move into the inside of the groove 72 through the slide rod 74, thereby releasing the restriction on the main filter 54. When the spring on the left side of the auxiliary filter plate 62 shrinks to the limit, the main baffle plate 71 completely moves into the inside of the groove 72, releasing the closure of the main airway 55, and the filter 52 moves to the right side of the filter 52 under the action of the spring and fits the right inner wall of the main slide 51. In this process, the filter 52 drives the long gear 85 to reverse through the tooth groove 53, and the long gear 85 drives the connecting plate 93 and the auxiliary baffle 9 through the screw rod 86. 2 moves to the inside of the auxiliary slide 61 to completely close the auxiliary air channel 65. The auxiliary filter plate 62 drives the auxiliary filter screen 63 to move to the right side of the auxiliary filter screen 63 and fit the left side of the auxiliary baffle plate 92 under the action of the spring. The transmission plate 64 drives the threaded rod 83 to reverse through the short gear 82. The threaded rod 83 drives the slide bar 74 to move to the original position, and then controls another cylinder 104 to contract and drive the short plate 105 to release the blockage of the auxiliary water inlet 106. The cleaning liquid cleans the auxiliary filter screen 63 through the auxiliary water inlet 106 under the action of the water pump and drives the impurities to the inside of the recovery barrel 102 through the auxiliary water inlet 106, and is discharged through the valve on the back of the recovery barrel 102. When the discharged cleaning liquid is free of impurities, the other cylinder 104 is controlled to extend and drive the short plate 105 to re-close the auxiliary water inlet 106.
