Description

Technical Field

[0001] The invention relates to the technical field of zinc oxide processing, in particular to a collecting device in a filterable zinc oxide production process. Background Art

[0002] Zinc oxide is an important additive and is widely used in the production of rubber products. In the rubber processing process, zinc oxide can promote vulcanization reaction, increase rubber hardness, and improve rubber physical properties. In addition, zinc oxide can also increase the wear resistance, oxidation resistance and weather resistance of rubber products, and improve the service life of rubber products.

[0003] In the production process of zinc oxide, impurities in zinc oxide need to be removed to improve the purity of zinc oxide. There are two current methods for filtering zinc oxide. One is to directly filter the dry zinc oxide, which has a poor filtering effect. The other is to filter the zinc oxide into a zinc oxide suspension. Although this method increases the processing steps, the zinc oxide obtained has a higher purity.

[0004] When the second method mentioned above is used to filter zinc oxide, impurities will adhere to the filter plate as the filtration proceeds, causing some filter holes to be blocked, and long-term standing will cause the zinc oxide suspension to precipitate, both of which affect the filtration effect. Summary of the invention

[0008] As a further solution of the present invention: the return pump structure includes a pump cylinder body detachably mounted on the filter box body, a sealing plug is sealingly and slidably installed in the pump cylinder body, a follower shaft coaxial with the sealing plug and passing through the pump cylinder body is connected to the sealing plug, the follower shaft is slidably connected to the sliding hook plate, a first cylindrical spring is also sleeved on the follower shaft, one end of the first cylindrical spring is connected to the sealing plug, and the other end is connected to the side wall of the pump cylinder body.

[0009] As a further solution of the present invention: the blocking structure includes a regulating valve tube connected to the discharge port, a rotating ring and a fixed ring are arranged in the regulating valve tube, and through holes are arranged on the rotating ring and the fixed ring. When the through holes on the rotating ring and the fixed ring coincide with each other, the regulating valve tube is conductive.

[0010] As a further solution of the present invention: the rotating ring is rotatably connected with the fixed ring and sealed, and the rotating ring is connected with a rotating sleeve coaxial therewith; The follower shaft is connected with a connecting shaft, the connecting shaft is provided with a convex shaft, and the convex shaft is slidably connected with a guide groove provided on the rotating sleeve.

[0011] As a further solution of the present invention: the guide groove comprises a first vertical groove body arranged along the axial direction of the rotating sleeve, and one end of the first vertical groove body facing the regulating valve pipe is connected to a spiral groove body.

[0012] As a further solution of the present invention: the lifting structure includes a connecting ring coaxially fixedly connected to the action end of the electric telescopic rod, and a sleeve is slidably provided on the connecting ring, and the sleeve is adapted to the sliding hook plate.

[0013] As a further solution of the present invention: an end of the sliding hook plate away from the filter box is formed with an inclined guide surface; The support structure comprises a plurality of guide plates arranged on the filter box body, wherein a slide groove is formed on the guide plate, a sliding plate is slidably installed in the slide groove, a transverse shaft slidably connected to the sliding hook plate is installed on the sliding plate, a second column spring is sleeved on the transverse shaft, one end of the second column spring is connected to the sliding hook plate, and the other end is connected to the sliding plate; A groove wheel is also rotatably mounted on the sliding hook plate, and the groove wheel is rollingly matched with the hysteresis groove arranged on the guide plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By means of the deflection plate and the filter box, when the zinc oxide suspension is poured into the filter box, the zinc oxide suspension can flow out from the filter holes under the action of its own gravity, and the filter holes are used to filter impurities, and the zinc oxide suspension can rotate with the filter box to generate centrifugal force to accelerate the zinc oxide suspension to pass through the filter holes, thereby improving the filtering speed. At the same time, when the zinc oxide suspension makes a circular motion, the deflection plate is in the first state and can generate a downward pressure on the zinc oxide suspension, so that the zinc oxide suspension is pressurized, and the filtering speed of the zinc oxide suspension is further improved. By setting up the return pump structure, it is possible to draw outside air into the pump cylinder body, and then pressurize the air to quickly pass through the filter holes and enter the filter box body. On the one hand, the impurities attached to the filter holes are washed away, so that the filter holes originally blocked by impurities are made conductive, so that the filtering performance of the filter holes can be restored during subsequent filtration. On the other hand, the air moves upward in the filter box body, which can perform secondary mixing on the zinc oxide suspension, effectively preventing the zinc oxide suspension from settling. By setting the blocking structure, when the compressed air quickly passes through the filter hole and enters the filter box, the regulating valve pipe can be in a blocked state, thereby ensuring that the compressed air in the pump cylinder can only enter the filter box through the filter hole, and will not escape from the discharge port to cause pressure relief, thereby increasing the speed and air volume of the compressed air entering the filter box through the filter hole, and improving the effect of flushing away impurities; By setting the staggered assembly, when the ring acts on the sliding hook plate, the sealing plug can move upward. At the same time, after the sliding hook plate moves to a predetermined position, the sliding hook plate can be separated from the ring, and under the joint action of the first column spring and the second column spring, the follower shaft and the sealing plug are accelerated to move downward, thereby increasing the speed of the compressed air passing through the filter hole. At the same time, the deflection plate can be switched to the second state, thereby reducing the pressure of the zinc oxide suspension on the filter hole and improving the smoothness of the compressed air passing through the filter hole.

DETAILED DESCRIPTION

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0029] See also Figure 1 to Figure 10 In an embodiment of the present invention, a collection device in a filterable zinc oxide production process includes: a frame structure 1, a covering frame plate 11, a deflection plate 7, a pump back structure, a blocking structure and a staggered assembly, which can realize the suction of external air into the pump cylinder body 12, and then pressurize the air to quickly pass through the filter hole 201 into the filter box 2, and on the one hand, the impurities attached to the filter hole 201 are washed away, so that the filter hole 201 originally blocked by impurities is conductive, and the filtering performance of the filter hole 201 can be restored during subsequent filtering, and on the other hand, the air moves upward in the filter box 2, which can perform secondary mixing on the zinc oxide suspension and effectively prevent the zinc oxide suspension from precipitating, as follows: A filter box 2 is rotatably mounted on the frame structure 1, and a plurality of groups of filter holes 201 are equidistantly arranged on the side walls of the filter box 2. Furthermore, a plurality of baffles 202 are equidistantly arranged in the filter box 2, and the baffles 202 are arranged along the radial direction of the filter box 2. A driving device 28 mounted on the frame structure 1 is coaxially fixedly connected to the filter box 2. When the driving device 28 is working, the filter box 2 connected thereto will perform a circular motion, and the baffles 202 in the filter box 2 will also perform a circular motion. At this time, driven by the baffles 202, the stationary zinc oxide suspension in the filter box 2 can quickly enter a rotating state and generate centrifugal force. Under the action of the centrifugal force, the zinc oxide suspension has a tendency to move toward the cylinder wall of the filter box 2, thereby accelerating the speed of the zinc oxide suspension passing through the filter holes 201.

[0030] The cover frame plate 11 is arranged on the side wall of the filter box 2, and the zinc oxide suspension passing through the filter hole 201 can enter the cover frame plate 11. The cover frame plate 11 is provided with a discharge port. It is supplemented that an annular collecting device (not shown in the figure) is also installed on the frame structure 1. The annular collecting device corresponds to the discharge port, and the annular collecting device is coaxial with the filter box 2, so that when the zinc oxide suspension is discharged through the discharge port, it can be collected by the annular collecting device; The deflection plate 7 is connected to the frame structure 1, and the deflection plate 7 has a first state and a second state that are switched by being pulled. When the deflection plate 7 is in the first state, it can generate downward pressure on the zinc oxide suspension in the rotating state. For the convenience of understanding, the plane passing through the center line of the rotation axis of the deflection plate 7 is taken as the reference plane. When the deflection plate 7 is in the first state, the end of the deflection plate 7 away from the rotation axis is below the reference plane. When the deflection plate 7 is in the second state, the end of the deflection plate 7 away from the rotation axis is above the reference plane, and the driving device The direction in which the filter box 2 is driven to rotate by the device 28 is constant. Taking a zinc oxide particle at a certain location as an example, when it rotates with the filter box 2, it will first pass through the rotation axis of the deflection plate 7, and then pass through the end of the deflection plate 7 away from its rotation axis. Under such a setting, when the zinc oxide suspension follows the filter box 2 to make a circular motion, and when the deflection plate 7 is in the first state, the deflection plate 7 can give a downward pressure to the zinc oxide suspension, that is, to pressurize the zinc oxide suspension, so that the zinc oxide suspension can quickly pass through the filter hole 201.

[0031] A fixed shaft 4 is installed on the frame structure 1, and a mounting portion 8 is connected to the end of the fixed shaft 4, and the mounting portion 8 is rotatably connected to the deflection plate 7; An electric telescopic rod 3 is also fixedly mounted on the frame structure 1 , and an action end of the electric telescopic rod 3 is connected to a connecting piece 5 , a pulling rod 6 is rotatably mounted on the connecting piece 5 , and one end of the pulling rod 6 away from the connecting piece 5 is connected to the deflection plate 7 .

[0032] When in use, zinc oxide (including impurities) is first poured into the prefabricated box, and a zinc oxide suspension is formed by stirring. Then, the zinc oxide suspension is poured into the rotating filter box 2. At this time, under the action of the baffle 202, the zinc oxide suspension can follow the filter box 2 to make a circular motion. At this time, by controlling the action of the electric telescopic rod 3, the connecting piece 5 connected thereto can achieve a change in height, and the deflection plate 7 is driven by the pulling rod 6 to achieve state switching.

[0033] It should be noted that after the zinc oxide suspension is poured into the filter box 2, the deflection plate 7 can be kept in a horizontal state first, so that the zinc oxide suspension can quickly follow the filter box 2 to rotate. After the zinc oxide suspension follows the filter box 2 to rotate, the deflection plate 7 is switched to the first state by controlling the electric telescopic rod 3 to move. At this time, the deflection plate 7 can generate downward pressure on the rotating zinc oxide suspension.

[0034] Through the above arrangement, when the zinc oxide suspension is poured into the filter box 2, the zinc oxide suspension can flow out from the filter hole 201 under the action of its own gravity, and the filter hole 201 is used to filter impurities. The zinc oxide suspension can rotate with the filter box 2 to generate centrifugal force to accelerate the zinc oxide suspension to pass through the filter hole 201, thereby improving the filtration speed. At the same time, when the zinc oxide suspension makes a circular motion, the deflection plate 7 is in the first state and can generate a downward pressure on the zinc oxide suspension, so that the zinc oxide suspension is pressurized, and the filtration speed of the zinc oxide suspension is further improved.

[0035] See also Figure 1 , Figure 2 , Figure 6~Figure 8 , the return pump structure is connected to the cover frame plate 11, and the return pump structure can input compressed air into the cover frame plate 11; The return pump structure includes a pump cylinder body 12 detachably mounted on the filter box body 2, a sealing plug 13 is sealingly and slidably mounted in the pump cylinder body 12, a follower shaft 14 coaxial with the pump cylinder body 12 and penetrating the pump cylinder body 12 is connected to the sealing plug 13, and the follower shaft 14 is slidably connected to the sliding hook plate 17, wherein two one-way valves 16 are arranged on the pump cylinder body 12, one of the one-way valves 16 is arranged on the pipeline connecting the pump cylinder body 12 and the covering frame plate 11, and the conducting direction of the one-way valve 16 is from the pump cylinder body 12 to the covering frame plate 11, and the conducting direction of the other one-way valve 16 is from the outside to the pump cylinder body 12; Furthermore, a limiting groove is formed on the follower shaft 14, and the limiting groove is slidably matched with a limiting protrusion provided on the pump cylinder body 12 to achieve axial locking of the follower shaft 14; The follower shaft 14 is also sleeved with a first cylindrical spring 15 , one end of the first cylindrical spring 15 is connected to the sealing plug 13 , and the other end of the first cylindrical spring 15 is connected to the side wall of the pump cylinder body 12 .

[0036] As the filtration proceeds, more and more impurities are filtered out of the zinc oxide suspension. These impurities will also adhere to the inner wall of the filter box 2 under the action of centrifugal force and pressure, so that part of the filter holes 201 are blocked. As the filtration of the zinc oxide suspension proceeds, the filtration speed will decrease. At this time, the staggered assembly will act to drive the follower shaft 14 to move upward, so that the sealing plug 13 moves upward, and while compressing the first cylindrical spring 15, a negative pressure is generated at the lower part of the pump cylinder body 12. Under the action of the negative pressure, the outside air enters the pump cylinder body 12 through one of the one-way valves 16. Then, after the sealing plug 13 rises to the moving position, the staggered assembly is released. The follower shaft 14 is released. At this time, under the action of the first cylindrical spring 15, the air in the pump cylinder 12 can be compressed and quickly enter the covering frame plate 11 through another one-way valve 16, and then enter the inside of the filter box 2 from the outside of the filter hole 201. In this process, by quickly pouring air into the filter box 2, on the one hand, impurities attached to the filter hole 201 can be washed away, so that the filter hole 201 originally blocked by impurities can be conducted, and the filtering performance of the filter hole 201 can be restored during subsequent filtering. On the other hand, the air moves upward in the filter box 2, which can perform secondary mixing on the zinc oxide suspension and effectively prevent the zinc oxide suspension from settling.

[0037] It is worth noting that, although the impurities can be separated from the filter holes 201 by injecting air into the filter box 2 so that the filter holes 201 maintain good filtering performance, the impurities will still be in the filter box 2 and may still clog the filter holes 201 again. As the filtering proceeds, the amount of impurities will increase and the probability of the filter holes 201 being blocked will also increase. Therefore, in order to ensure the filtering performance of the filter holes 201, it is still necessary to clean the impurities in the filter box 2 after a certain filtering period.

[0038] Through the above arrangement, it is possible to draw outside air into the pump cylinder 12, and then pressurize the air to quickly pass through the filter holes 201 into the filter box 2. On the one hand, impurities attached to the filter holes 201 are washed away, so that the filter holes 201 originally blocked by impurities are made conductive, and the filtering performance of the filter holes 201 can be restored during subsequent filtration. On the other hand, the air moves upward in the filter box 2, which can perform secondary mixing on the zinc oxide suspension and effectively prevent the zinc oxide suspension from settling.

[0039] See also Figure 7~Figure 9 The blocking structure is connected to the discharge port, and the blocking structure is linked to the pump back structure, so that the discharge port can be blocked when the pump back structure is in action; The blocking structure includes a regulating valve tube 18 connected to the discharge port, wherein a rotating ring 21 and a fixed ring 22 are arranged in the regulating valve tube 18, and through holes 23 are arranged on the rotating ring 21 and the fixed ring 22. When the through holes 23 on the rotating ring 21 and the fixed ring 22 overlap, the regulating valve tube 18 is conductive; The rotating ring 21 is rotatably connected with the fixed ring 22 and is sealed and fitted therewith. The rotating ring 21 is connected with a rotating sleeve 20 coaxial therewith. The follower shaft 14 is connected to a connecting shaft 19, and a convex shaft 1901 is provided on the connecting shaft 19. The convex shaft 1901 is slidably connected to a guide groove provided on the rotating sleeve 20. The guide groove includes a first vertical groove body 2001 provided along the axial direction of the rotating sleeve 20, and the first vertical groove body 2001 is connected to a spiral groove body 2002 at one end facing the regulating valve tube 18.

[0040] In the filtering state, the through holes 23 on the rotating ring 21 and the fixed ring 22 are in an overlapped state, so that the regulating valve tube 18 is in a conducting state. At this time, the filtered zinc oxide suspension can flow into the annular collecting device through the regulating valve tube 18. In this state, the convex shaft 1901 is at the end of the spiral groove body 2002 away from the first vertical groove body 2001. When the sealing plug 13 moves upward to extract external air, the follower shaft 14 will also drive the connecting shaft 19 to move upward. At this time, the convex shaft 190 1 will move along the spiral groove body 2002 and the first vertical groove body 2001 in sequence, and when the convex shaft 1901 moves in the spiral groove body 2002, the rotating sleeve 20 will also rotate, and make the rotating ring 21 rotate, so that the through holes 23 on the rotating ring 21 and the fixed ring 22 are gradually misaligned. When the convex shaft 1901 moves into the first vertical groove body 2001, the through holes 23 on the rotating ring 21 and the fixed ring 22 are completely misaligned. In this state, the regulating valve pipe 18 is in a blocked state.

[0041] When the sealing plug 13 moves in the opposite direction to compress the air into the filter box 2, the convex shaft 1901 will move along the first vertical groove 2001 and the spiral groove 2002, so that the regulating valve tube 18 can remain in a blocked state. At this time, the compressed air in the pump cylinder body 12 can only enter the filter box 2 through the filter hole 201, and will not escape from the discharge port to cause pressure relief, thereby increasing the speed and air volume of the compressed air entering the filter box 2 through the filter hole 201, and improving the effect of flushing away impurities.

[0042] After the sealing plug 13 is reset, the convex shaft 1901 will also be reset, and the regulating valve tube 18 will resume the conducting state.

[0043] Through the above-mentioned arrangement, when the compressed air quickly passes through the filter hole 201 and enters the filter box 2, the regulating valve tube 18 can be in a blocked state, thereby ensuring that the compressed air in the pump cylinder 12 can only enter the filter box 2 through the filter hole 201, and will not escape from the discharge port to cause pressure release, thereby increasing the speed and air volume of the compressed air entering the filter box 2 through the filter hole 201 and improving the effect of flushing away impurities.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 , Fig.10 The staggered assembly is arranged on the frame structure 1, and the staggered assembly includes a lifting structure and a supporting structure. The supporting structure is connected with a sliding hook plate 17 which is slidably connected with the return pump structure. When the lifting structure is in motion, it can cooperate with the sliding hook plate 17 to make the return pump structure move, and when the lifting structure moves a predetermined stroke, the supporting structure can drive the sliding hook plate 17 to separate from the lifting structure; The lifting structure includes a connecting ring 9 coaxially fixedly connected to the action end of the electric telescopic rod 3, a sleeve ring 10 is slidably sleeved on the connecting ring 9, the sleeve ring 10 is adapted to the sliding hook plate 17, and the sleeve ring 10 can rotate relative to the connecting ring 9; The end of the sliding hook plate 17 away from the filter box 2 is formed with an inclined guide surface 1701; The support structure includes a plurality of guide plates 27 arranged on the filter box 2, wherein a slide groove 2701 is formed on the guide plate 27, a slide plate 26 is slidably installed in the slide groove 2701, a transverse shaft 25 slidably connected to the slide hook plate 17 is installed on the slide plate 26, a second column spring 24 is sleeved on the transverse shaft 25, one end of the second column spring 24 is connected to the slide hook plate 17, and the other end is connected to the slide plate 26; The sliding hook plate 17 is also rotatably mounted with a groove wheel 1702, and the groove wheel 1702 is rollingly matched with the retardation groove arranged on the guide plate 27, and the retardation groove includes a second vertical groove body 2703 and a horizontal groove body 2704 arranged vertically on the guide plate 27, and an inclined groove body 2702 is arranged at one end of the second vertical groove body 2703 away from the horizontal groove body 2704; When the groove wheel 1702 moves upward along the inclined groove body 2702 , the sliding hook plate 17 can be driven to move toward the filter box 2 to separate from the collar 10 .

[0045] When in the filtering state, the deflection plate 7 is in the first state, at which time the collar 10 is at the lower part of the sliding hook plate 17, and when the filter hole 201 is blocked, the action end of the electric telescopic rod 3 will move upward, at which time the connecting ring 9 and the connecting piece 5 will move upward, so that the deflection plate 7 switches from the first state to the second state, and at the same time the collar 10 acts on the sliding hook plate 17 to move the follower shaft 14 and the sealing plug 13 upward, so that air is drawn into the pump cylinder body 12, and under the support of the second column spring 24, the groove wheel 1702 is in contact with the side of the second vertical groove body 2703 away from the horizontal groove body 2704, and as the sliding hook plate 17 rises, the groove wheel 1702 moves along the second vertical groove body 2703 until the sliding hook plate 17 moves to the predetermined position, and the groove wheel 1702 moves along the inclined groove body 2702 , and the sliding hook plate 17 moves toward the filter box body 2, compressing the second cylindrical spring 24 while gradually misaligning the sliding hook plate 17 with the collar 10. After the two are completely misaligned, driven by the first cylindrical spring 15, the sealing plug 13 can compress the air in the pump cylinder body 12, and at the same time, the second cylindrical spring 24 releases elastic potential energy, causing the groove wheel 1702 to move in the opposite direction along the inclined groove body 2702. The first cylindrical spring 15 and the second cylindrical spring 24 work together to accelerate the speed of the follower shaft 14 and the sealing plug 13 when moving downward, and in this state, the deflection plate 7 is in the second state, and has an upward force on the zinc oxide suspension to reduce the pressure of the zinc oxide suspension's own gravity on the filter hole 201, reduce the pressure of the compressed air flowing through the filter hole 201, and make the compressed air pass through the filter hole 201 more smoothly.

[0046] When the sealing plug 13 is reset, the impurities at the filter hole 201 are washed away, and the action end of the electric telescopic rod 3 will move downward again, so that the connecting ring 9 drives the collar 10 to move downward, and when the collar 10 abuts against the inclined guide surface 1701, the sliding hook plate 17 moves toward the filter box 2 again, and the groove wheel 1702 moves along the horizontal groove body 2704 to make way, and when the collar 10 moves to the lower part of the sliding hook plate 17, the sliding hook plate 17 will be reset again under the drive of the second cylindrical spring 24, so that the above action can be repeated when the filter hole 201 is blocked next time.

[0047] It should also be noted that a stop ring is formed in the pump cylinder body 12. In the initial state, the first cylindrical spring 15 is in a compressed state. At this time, the sealing plug 13 is in contact with the stop ring. At the same time, under the obstruction of the stop ring, it can prevent the sliding hook plate 17 from continuing to move downward under pressure when the ring 10 abuts against the inclined guide surface 1701.

[0048] Through the above arrangement, when the collar 10 acts on the sliding hook plate 17, the sealing plug 13 can move upward. At the same time, after the sliding hook plate 17 moves to the predetermined position, the sliding hook plate 17 can be separated from the collar 10, and under the joint action of the first cylindrical spring 15 and the second cylindrical spring 24, the follower shaft 14 and the sealing plug 13 are accelerated to move downward, thereby increasing the speed of the compressed air passing through the filter hole 201. At the same time, the deflection plate 7 can be switched to the second state, thereby reducing the pressure of the zinc oxide suspension on the filter hole 201 and improving the smoothness of the compressed air passing through the filter hole 201.

[0049] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
