Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to an industrial energy-saving water purifier. Background Art

[0002] Industrial water purifier is a device used to treat industrial water. It uses physical filtration, chemical treatment, membrane separation and other technologies to remove impurities and pollutants in the water. Among them, flotation technology is the main industrial means in the sewage pre-treatment process. The flotation process mainly relies on a large number of dense micro-bubbles generated by the releaser to be passed into the sewage to be treated, and the charge carried by the bubbles themselves is used to entrain and adsorb the pollutants, and then float to the water surface through the buoyancy they are subjected to. Subsequently, the pollutants are treated using a scraping device to achieve a sewage treatment process. Among them, the pressure dissolved air flotation method is the main method for generating microbubbles in industrial water purifiers. It has the advantages of good microbubble generation effect, strong adaptability, and small footprint. Its principle is to pressurize and add gas to the dissolved air tank so that air molecules enter the gaps between water molecules through the gap filling effect, and then the high-pressure dissolved air water is rapidly dissipated and depressurized through the releaser, and the gas molecules in the water will be rapidly released and form a large number of dense microbubbles.

[0003] However, during the working process, the two discs of the air releaser are of a fixed structure, and the gap between the discs cannot be adjusted, which makes the gap prone to blockage. Once the releaser is blocked, it will directly affect the release amount of bubbles, thereby adversely affecting the oil removal effect. A solution is provided in the prior art. For example, patent application No. CN202310762662.1 provides an oil-water separation device by flotation. The patent provides an oil-water separation device by flotation, including a shaping mechanism for shaping the dissolved air releaser, wherein the dissolved air releaser includes a fixed disc, which is connected to the dissolved air pipeline, and a movable disc, which is slidably installed under the fixed disc, and the shaping mechanism includes a first clamping piece slidably installed on the top of the fixed disc, and the movable disc is clamped with the fixed disc through the first clamping piece. The cleaning effect of the release port is automatically detected by setting a detection mechanism, and the movable disc is fixed after being moved down in cooperation with the second clamping piece to ensure that the flushing and cleaning work is carried out smoothly. Only when the release port is 360 degrees around the release port When the range is cleaned, all the detection plates are deflected, and the movable disk automatically moves up and resets, realizing the automatic cleaning of the blockage of the release port, the automatic detection of the cleaning result, and the releaser automatically restoring the normal operation function after the detection of thorough cleaning. However, due to the presence of calcium, magnesium ions and sediment particles in the air-containing water, carbonate compounds will precipitate in the dissolved air releaser, and the carbon carbonate compound precipitate is hard in texture, with high hardness and strong adhesion. At the same time, when the dissolved air water enters the releaser, due to the special structural design inside the releaser, such as with gaps or specific decompression channels, the pressure of the dissolved air water will drop sharply, and the movable disk and the fixed disk will increase the distance between the two when cleaning, and then the opening will increase, causing the flow rate of the dissolved air water in the releaser to decrease. The reduction in flow rate means that the kinetic energy carried by the dissolved air water flow is weakened. When the kinetic energy is insufficient, it is difficult to effectively overcome the adhesion between the impurities and the wall of the releaser, and the carbonate compounds accumulated on the inner wall of the air releaser cannot be cleaned, which leads to a decrease in the flotation effect of the releaser. Summary of the invention

[0004] The purpose of the present invention is to provide an industrial energy-saving water purifier to solve the problem in the prior art that the carbonate compounds accumulated on the inner wall of the dissolved air releaser cannot be cleaned, resulting in a decrease in the flotation effect of the releaser.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An industrial energy-saving water purifier comprises a box, an air dissolving tank and a releaser. The box is provided with an air dissolving tank which is connected with an air pump and a water inlet pipe. The box is provided with a releaser which is connected with the air dissolving tank through an output pipe.

[0007] Specifically, the releaser includes a connecting tube, a guide block, a blade, a screw, a fixed disk and a movable disk. The upper end surface of the fixed disk is connected to the output pipe. The movable disk is coaxially installed in the fixed disk. The movable disk and the fixed disk are respectively provided with a plurality of No. 1 convex rings and No. 2 convex rings. The No. 1 convex ring and the No. 2 convex ring and the end surfaces thereof constitute a release cavity. The release cavity is respectively connected to the side wall of the fixed disk and the output pipe. A through hole is provided in the center of the movable disk. The through hole passes through the movable disk. A screw is connected to the axis of the fixed disk. The screw A reciprocating thread groove is provided on the top, a connecting cylinder is coaxially installed on the screw, a guide block is provided in the connecting cylinder and is slidably connected to the reciprocating thread groove, a plurality of blades are evenly arranged in an annular manner inside the through hole and are connected to the connecting cylinder, a discharge groove is provided in the fixed disk, the discharge groove is connected to the through hole, a trigger assembly is provided in the fixed disk, the trigger assembly is used to release the position restriction of the connecting cylinder when the pressure in the through hole is greater than the set value, and lock the connecting cylinder when the pressure in the through hole is less than the set value and the connecting cylinder moves to the set position.

[0008] It is easy to understand that with the accumulation of carbonate compounds on the inner wall of the dissolved air releaser, the pressure in the release chamber and the connected through holes in the releaser increases, thereby triggering the component to release the position restriction on the connecting tube, and at the same time, the dissolved air water flows out of the releaser through the through holes. During the process, the water flow pressure of the dissolved air water is converted under the action of the blades and drives the connecting tube and the movable disk connected thereto to rotate. Since the guide block on the connecting tube is slidably connected with the reciprocating thread groove on the screw, the movable disk moves toward the fixed disk along the axial direction under the cooperation of the reciprocating and connecting tubes. During the process, the movable disk and the fixed disk rotate relative to each other, and friction is generated between the movable disk and the fixed disk. Through the cooperation of the blades, the connecting tube and the screw, the water flow pressure of the dissolved air water is used to drive the movable disk to move closer to the fixed disk, and the movable disk and the fixed disk rub against each other, thereby peeling off the carbonate compound particles from the side wall of the release chamber, so as to solve the problem that the carbonate compounds accumulated on the inner wall of the dissolved air releaser cannot be cleaned in the prior art, thereby ensuring the flotation effect of the releaser.

[0009] Preferably, a sliding groove is provided on the side wall of the screw, and a block is slidably installed in the sliding groove, the block is U-shaped, and the side of the block close to the axis is connected to the screw through a compression spring, and both ends of the block extend out of the sliding groove under the elastic force of the compression spring, an inclined surface facing the through hole is provided at the lower end of the block, the retaining ring is fitted with the inclined surface, and a groove matching the upper end of the block is opened on the connecting tube.

[0010] Under normal working conditions, the upper end surface of the retaining ring is slidably connected with the connecting tube and the lower end surface of the movable disk respectively to prevent the dissolved gas water from flowing out of the discharge trough, thereby preventing the movable disk from rotating back and forth, affecting the flotation effect of the released gas, and at the same time, the two ends of the card block are stuck in the corresponding positions, playing a role of fixing and limiting, and at the same time, the compression spring will provide a certain pre-tightening force to the card block, so that the card block is kept in a specific initial position, maintaining a stable connection relationship between the various components, with the accumulation of carbonate compounds on the inner wall of the dissolved gas releaser, the pressure of the release chamber and the connected through-hole in the releaser increases, thereby pushing the retaining ring to separate from the connecting tube and the lower end surface of the movable disk, and move downward, and release the restriction on the dissolved gas water in the through-hole. During the process, the lower end surface of the retaining ring cooperates with the inclined surface on the card block, and the card block slides in the slide groove. At this time, the other end of the card block is separated from the card groove, and the restriction on the connecting tube is released by the cooperation of the card block and the retaining ring using the increased internal pressure of the through-hole, thereby making the movable disk move closer to the fixed disk, and the carbonate compound particles are peeled off from the side wall of the release chamber.

[0011] During the movement of the card block, the compression spring is squeezed. At the same time, after the carbonate compounds accumulated on the inner wall of the releaser are cleaned, it returns to the initial point under the action of the reciprocating thread. At this time, the through hole is lowered and restored to the preset value due to the cleaning of the accumulated carbonate compounds. At this time, the elastic potential energy of the compression spring is released, pushing the card block out of the slide groove. Under the action of the inclined surface, the retaining ring is reconnected with the connecting tube and the lower end face of the movable disk. At the same time, the card block at the other end is re-matched with the card groove to prevent the dissolved gas from flowing out of the discharge trough, thereby ensuring the stability of the flotation effect of the releaser.

[0012] Preferably, the reciprocating thread groove includes a descending section and an ascending section. When the slot is matched with the block, the guide block is located in the descending section and is at a distance D from the bottom of the ascending section of the thread, D=3-5mm, and the distance between the guide block and the top of the ascending section of the thread is equal to the width of the release chamber. The pitch of the reciprocating thread is P, and D is not equal to nP / 2, where n is an integer.

[0013] When dissolved air water flows through the through hole, the movable disk and the connecting cylinder are driven to rotate under the action of the blades, and then the guide block is driven to slide in the reciprocating thread groove. At this time, the guide block is located in the descending section and the distance between it and the card block is shortened, and the distance between the movable disk and the fixed disk is increased. At this time, the blockage in the release chamber is discharged under the action of dissolved air water, and the function of cleaning the larger blockage in the dissolved air releaser is realized. As the guide block comes to the ascending section, the moving direction of the guide block changes, and the movable disk moves closer to the fixed disk. When it reaches the end point of the ascending section, friction occurs between the movable disk and the fixed disk, and then the carbonate compound particles are peeled off from the side wall of the release chamber, so as to solve the problem that the carbonate compounds accumulated on the inner wall of the dissolved air releaser cannot be cleaned in the prior art. As the guide block continues to move forward, the guide block returns to the descending section, and the movable disk is separated from the fixed disk until the card block cooperates with the card slot. At this time, the guide block returns to the original set position, and stops when the guide block and the bottom of the threaded ascending section are D, so that the distance between the movable disk and the fixed disk returns to the initial preset value, ensuring that the quality of the bubbles released by the releaser is stable. When D is not equal to nP / 2, the guide block is located at the same height as the threaded descending section and the ascending section, and the guide block can be located in different radial directions of the connecting tube, respectively, so as to avoid the card block being stuck in the card slot during the ascending process of the connecting tube, so that the movable disk cannot continue to clean the carbonate compounds, causing the movable disk to move directly upwards when cleaning next time, and being stuck and unable to continue working when encountering particles of objects with greater hardness.

[0014] Preferably, a slip ring groove is coaxially opened at the connection between the output pipe and the fixed disk, the opening of the slip ring groove vertically points to the release chamber, a sealing ring is slidably installed in the slip ring groove, the sealing ring includes a sealing part and a matching part, the upper end face of the sealing part is connected to the lower end face of the matching part, the inner diameter of the matching part is smaller than the inner diameter of the sealing part, the axial length of the sealing part is equal to the distance between the fixed disk and the movable disk, and a retaining ring is arranged on the side of the slip ring groove close to the axis, and the horizontal projection of the retaining ring is located at the projection of the matching part.

[0015] When in normal working state, the pressure in the release chamber acts on the matching ring through the slip ring groove to keep the sealing part in the slip ring. Through the communication between the slip ring groove and the release chamber, the pressure in the release ring acts on the sealing ring to prevent the sealing ring from extending, hindering the flow of dissolved air and water in the release chamber, avoiding turbulence in the release chamber, and thus affecting the flotation effect of the releaser. When the retaining ring is separated from the connecting tube and the lower end face of the movable disk, the solution water in the release chamber can be discharged from the through hole. At this time, the pressure in the release chamber is reduced. At this time, the weight of the sealing ring is greater than the pressure in the release chamber. At this time, the sealing part on the sealing ring extends out of the slip ring groove and fits with the upper end face of the movable disk. At this time, the dissolved air and water in the release chamber cannot flow out of the release chamber and can only flow to the through hole. Through the design of the sealing ring, the dissolved air and water flow to the through hole. At this time, the water flow pressure acting on the blade increases, thereby increasing the torque on the blade, increasing the force between the movable disk and the fixed disk, and thus improving the cleaning effect between the movable disk and the fixed disk. The clamping ring is used to limit the movement of the matching part, thereby preventing the sealing ring from being separated from the slip ring groove and affecting the normal operation of the equipment.

[0016] Preferably, the No. 1 convex ring is eccentrically arranged, the distance between the axis of the adjacent No. 1 convex ring and the axis of the No. 2 convex ring is equal to the maximum distance between the side walls of the adjacent No. 1 convex ring and the No. 2 convex ring, and the axis of the No. 2 convex ring is colinear with the axis of the screw.

[0017] The distance between the axis center of the No. 1 convex ring and the axis center of the No. 2 convex ring is equal to the spacing between the side walls of the adjacent No. 1 convex ring and the No. 2 convex ring. At this time, the horizontal projections of the side walls of the adjacent No. 1 convex ring and the No. 2 convex ring are tangent. When the movable disk rotates, the friction force generated by the side walls of the adjacent No. 1 convex ring and the No. 2 convex ring can scrape the impurities accumulated on the side walls off the surface. The impurities on the side walls of the No. 1 convex ring and the No. 2 convex ring are cleaned by utilizing the rotation of the movable disk, thereby ensuring the floating air effect of the releaser.

[0018] Preferably, a collecting groove is provided at the connection between the side walls of both sides of the No. 1 convex ring and the movable disk, and the collecting groove is connected to the discharge groove. A discharge groove is provided between the lower end surface of the movable disk and the fixed disk, and the discharge groove is connected to the outer wall of the fixed disk.

[0019] The collecting trough is used to collect the carbonate compounds cleaned off the surfaces of the movable disk and the fixed disk to avoid their re-accumulation in the releaser and to prevent the movable disk and the fixed disk from getting stuck. The discharge trough is respectively connected with the outer wall of the fixed disk, the through hole and the collecting trough. When the dissolved air water is discharged from the releaser through the through hole through the discharge trough, the dissolved air water flows in the discharge trough during the process. Due to the structure of the channel and the power of the water flow, its flow rate is accelerated. At this time, the fluid pressure in the discharge trough is reduced, and the carbonate compounds in the collecting trough connected thereto flow into the discharge trough under pressure and then are discharged out of the releaser. Through the design of the collecting trough and the discharge trough, the cleaned carbonate compounds are taken away from the releaser by the flow of dissolved air water, so as to avoid the jamming of the movable disk caused by the accumulation of carbonate compounds, and the negative pressure generated by the high-speed water flow is used to adsorb impurities inside the collecting trough, which helps to improve the slag discharge effect of the collecting trough and further avoid the jamming of the movable disk caused by the accumulation of internal impurities.

[0020] Preferably, the discharge trough is a two-stage stepped trough, and the fixed plate is provided with a support block located in the horizontal projection of the large diameter section of the discharge trough, one side of the support block is slidably connected to the lower end surface of the movable plate and is located in the small diameter section of the discharge trough, and the other end of the support block is elastically connected to the fixed plate.

[0021] Under normal working conditions, the pressure in the release chamber is relatively high. At this time, the movable disk will bend due to the pressure. The bending of the movable disk will cause interference between it and the fixed disk, the No. 1 convex ring and the No. 2 convex ring, which will lead to the problem that the equipment cannot operate normally. Therefore, a support block is arranged in the discharge trough, and the support block is slidably installed on the fixed disk and is slidably connected to the lower end surface of the movable disk. The support of the lower end surface of the movable disk by the support block can prevent the movable disk from bending due to pressure, which will lead to the problem that the equipment cannot operate normally. When the dissolved air water comes into the continuous discharge trough, since the support block and the fixed disk are elastically connected, the water flow pushes the support block and then squeezes it. At this time, the support block slides, and the lower end surface of the movable disk of the support block is separated, thereby releasing the support and limiting of the movable disk. Through the setting of the support block, the support for the movable disk is guaranteed, and the movement of the movable disk is not interfered with during cleaning.

[0022] Preferably, a plurality of guide grooves are annularly provided on the side wall of the No. 1 convex ring, the inclination direction of the guide grooves is the same as the rotation direction of the ascending section, and the guide grooves are connected to the collecting grooves.

[0023] Through the inclined design of the guide groove and the rotation of the movable disk, an extrusion force is generated towards the collecting groove for the internal impurities. While the side walls of the No. 1 convex ring and the No. 2 convex ring are frictionally cleaned, the impurities are squeezed into the collecting groove, thereby improving the slag discharge effect of the collecting groove and avoiding the jamming of the movable disk. The setting of the guide groove can reduce the contact area with the carbonate compounds, increase the extrusion force on the carbonate compounds, make the carbonate compounds easier to break, and effectively improve the cleaning effect of the releaser.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention uses the water pressure of dissolved air water to drive the movable disk to approach the fixed disk through the coordination of the connecting tube, blades, screw, fixed disk and movable disk, and makes the movable disk and the fixed disk rub against each other, thereby peeling off the impurities from the side wall of the release chamber, thereby reducing the setting of additional power sources and reducing the manufacturing cost of the equipment. At the same time, the design of the reciprocating thread on the screw allows the movable disk to separate, rub and reset from the fixed disk, ensuring the cleaning of carbonate compounds on the side wall while achieving the cleaning of larger blockages in the dissolved air releaser, avoiding the reduction of the flotation effect of the releaser.

[0026] 2. The present invention adopts the design of the trigger component and provides pre-tightening force through the compression spring, so that the block limits the retaining ring and the connecting tube, thereby preventing the movable disk from reciprocating and rotating and affecting the flotation effect of the released gas. At the same time, it can adapt to the pressure changes in the through hole, and the contact pair releases the restriction on the connecting tube, so that the movable disk moves closer to the fixed disk and then cleans the impurities on the side wall of the release chamber, thereby ensuring that the flotation releaser is always in a relatively good working state, ensuring the flotation effect of the releaser, and it is automatically triggered by the internal water pressure, and does not require manual control for cleaning, so it is more convenient to use.

[0027] 3. The inclined design of the guide groove and the rotation of the movable disk produce an extrusion force toward the collecting groove for the internal impurities. While the side walls of the No. 1 convex ring and the No. 2 convex ring are cleaned by friction, the impurities are squeezed into the collecting groove, thereby improving the slag discharge effect of the collecting groove and avoiding the jamming of the movable disk. The setting of the guide groove can reduce the contact area with the carbonate compounds, increase the extrusion force on the carbonate compounds, make the carbonate compounds easier to break, and effectively improve the cleaning effect of the releaser.

[0043] Working principle: when sewage needs to be purified, the sewage is put into the box 1 through the water pipe, and water is injected into the air dissolving tank 11 through the water inlet pipe 13. The air pump 12 injects gas into the air dissolving pump 12 and merges it with water to form dissolved air water. The dissolved air water comes to the releaser 14 through the output pipe 15 connected thereto, and the dissolved air water comes to the release chamber 16 between the movable disk 3 and the fixed disk 2. At this time, the dissolved air water flows through the No. 1 convex ring 31 and the No. 2 convex ring 32. The design of the No. 1 convex ring 31 and the No. 2 convex ring 32 makes the dissolved air water evenly distributed in all directions and comes to the side wall of the fixed disk 2. At this time, a large number of dense micro bubbles generated by the releaser 14 come into the sewage. The bubbles use the electric charge they carry to entrain and adsorb the pollutants and then float to the water surface through the buoyancy they receive. Then, the pollutants are treated by the scraping device to achieve sewage treatment.

[0044] As the releaser 14 is used, impurities are continuously accumulated on both sides of the releaser 14 and on the surfaces of the No. 1 convex ring 31 and the No. 2 convex ring 32. The accumulation of impurities causes the pressure in the releaser 14 to increase. Since the through hole 33 is connected to the release chamber 16, the pressure in the through hole 33 is suppressed to reach the set value. At this time, the dissolved air water pushes the retaining ring 37 to move downward along the axial direction of the screw 34. At this time, the retaining ring 37 is separated from the connecting tube 35 and the lower end surface of the movable disk 3. During the process, the block 38 is pushed to slide in the slide groove 345 toward the axial direction of the screw 34 through the action of the inclined surface 381. During the sliding process, the compression spring 39 is compressed, and the other end of the block 38 is connected to the card At this time, the block 38 restricts the contact of the connecting tube 35, and at the same time, part of the dissolved air water comes into the discharge groove 51 through the through hole 33. At this time, the support block 6 leaves the position below the movable disk 3 under the push of the water flow. During the process, since the other end of the support block 6 is elastically connected to the fixed disk 2, it is squeezed at this time, and the support and limit of the movable disk 3 are released. At the same time, part of the dissolved air water acts on the blade 36 through the through hole 33. Under the action of the blade 36, the water flow pressure of the dissolved air water is converted and drives the connecting tube 35 and the movable disk 3 connected thereto to rotate. Since the connecting tube 35 is coaxially connected to the screw 34, and the guide block 35 on the inner wall of the connecting tube 35 1 is slidably connected with the reciprocating thread on the screw rod 34, the guide block 351 is located in the descending section 343, and the distance D between the guide block 351 and the bottom of the ascending section 342 of the thread is 4 mm. At this time, due to the partial flow of dissolved air water to the vent hole, the pressure in the release chamber 16 is reduced. At this time, the sealing ring 41 force is greater than the pressure in the release chamber 16. Under the action of gravity, the sealing ring 41 extends from the sliding ring groove 4, and its lower end surface contacts the upper end surface of the movable disk 3. At this time, the dissolved air water in the release chamber 16 cannot flow out of the release chamber 16 and can only flow to the through hole 33. Through the design of the sealing ring 41, the dissolved air water flows to the through hole 33. At this time, the water flow pressure acting on the blade 36 increases. The torque on the blade 36 is increased, but due to the restriction of the matching portion 43 on the sealing ring 41 due to the jamming, and the axial length of the sealing portion 42 is equal to the distance between the fixed disk 2 and the movable disk 3, the sealing ring 41 stops sliding, and with the rotation of the connecting tube 35, the distance D between the guide block 351 and the bottom of the threaded ascending section 342 is less than 4 mm, and the movable disk 3 is driven downward at the same time. At this time, the distance between the movable disk 3 and the fixed disk 2 increases, and the lower end face of the sealing ring 41 is separated from the upper end face of the movable disk 3. At the same time, the blockage in the release chamber 16 is discharged under the action of the dissolved air water, thereby realizing the function of cleaning the larger blockage in the dissolved air releaser 14.

[0045] When the guide block 351 comes to the rising section 342, the moving direction of the guide block 351 changes, and the movable disk 3 moves closer to the fixed disk 2. During the process, the lower end face of the ring is re-fitted with the upper end face of the movable disk 3. During the process, as the movable disk 3 rises, the sealing ring 41 is pushed back into the slip ring. During the process, the side walls of the No. 1 convex ring 31 and the No. 2 convex ring 32 are in contact. When the movable disk 3 rotates, the friction force generated by the side walls of the adjacent No. 1 convex ring 31 and No. 2 convex ring 32 can scrape the impurities accumulated on the side walls off the surface. The impurities on the side walls of the No. 1 convex ring 31 and No. 2 convex ring 32 are cleaned by utilizing the rotation of the movable disk 3. When it reaches the end point of the rising section 342, the movable disk 3 rubs against the fixed disk 2, thereby Impurities are peeled off from the side wall of the release chamber 16. During the process, the inclined design of the guide groove 52 cooperates with the centrifugal force generated by the rotation of the movable disk 3 to guide the impurities on the side wall into the collecting groove 5, thereby improving the cleaning effect. The discharge groove 51 is respectively connected with the outer wall of the fixed disk 2, the through hole 33 and the collecting groove 5. When the dissolved air water is discharged from the through hole 33 through the discharge groove 51 to the outside of the releaser 14, the dissolved air water flows in the discharge groove 51. Due to the structure of the channel and the power of the water flow, its flow rate is accelerated. At this time, the fluid pressure in the discharge groove 51 is reduced, and the carbonate compounds in the collecting groove 5 connected thereto flow to the discharge groove 51 under pressure and then discharged from the outside of the releaser 14 to avoid the movable disk 3 being stuck due to the inability to discharge the carbonate compounds.

[0046] As the guide block 351 continues to move forward, the guide block 351 comes to the descending section 343, and the distance D between the guide block 351 and the bottom of the threaded ascending section 342 is greater than 4 mm. The movable disk 3 is separated from the fixed disk 2 and moves downward until the distance D between the guide block 351 and the bottom of the threaded ascending section 342 is equal to 4 mm. At this time, the distance between the movable disk 3 and the fixed disk 2 returns to the initial preset value. Since the impurities in the release chamber 16 have been cleaned, the pressure in the release chamber 16 returns to a normal value. At this time, the sealing ring 41 returns to the slip ring groove 4, and the compressed spring elastic potential energy is released. The two ends of the block 38 are pushed out of the slide groove 345. Under the action of the inclined surface 381, the retaining ring 37 is re-connected with the connecting tube 35 and the lower end surface of the movable disk 3 in a sliding manner. The other end of the block 38 cooperates with the slot 344 to limit the position of the connecting tube 35. At the same time, the elastic potential energy on the support block 6 is released, and the support block 6 re-supports the movable disk 3 to prevent the movable disk 3 from being bent due to pressure, thereby causing the equipment to fail to operate normally.
