Description

Technical Field

[0001] The invention relates to the technical field of powder mixing, in particular to a powder mixing device and a processing method for processing recycled rubber from waste tires. Background Art

[0002] Rubber powder is the abbreviation of rubber powder. It is generally processed from waste tires. Commonly used processing methods include: room temperature crushing method, freezing method, and room temperature chemical method. Rubber powder is widely used in sports plastic sports fields, playgrounds, rubber floor tiles, waterproof coils, waterproof coatings, highway modified asphalt, rubber products and other fields.

[0003] Many recycled rubber manufacturers will purchase a large number of waste tires, and then process the waste tires into rubber powder, and then put the rubber powder and other raw materials such as desulfurization additives into a rubber powder mixing device. After stirring, subsequent processing procedures are carried out. For example, China has authorized a patent: A rubber powder mixing device for processing waste tires into recycled rubber (authorization announcement number CN108638363B), which discloses a mixing bin and a third connecting rod, a first support rod, a first motor, a first connecting rod, a second connecting rod, a second support plate, a fixed block and other structures. The mixing of powders is achieved through stirring, thereby improving the mixing effect.

[0004] However, since the object of stirring is powder, powder floating and escaping is easy to occur during stirring, resulting in changes in the proportion of each component powder. Moreover, when the powder floats, the stirring effect on the powder makes the powder "flow" less likely, resulting in a lower degree of powder mixing. Summary of the invention

[0049] See also Figure 1 to Figure 10 In an embodiment of the present invention, a powder mixing device for processing recycled rubber from waste tires includes: a base 1, a rotating shaft 10, a follower structure, a trigger assembly, an energy storage assembly, a connecting assembly and a power assembly, so that when the connecting bracket 28 is actuated, the sealing plug 30 can be driven to act quickly, so that the compressed air can explosively escape from the through hole 1002, and under the cooperation of the inclined guide surface and the through hole 1002 with an opening inclined upward, the powder in the mixer 3 can be blown up as much as possible to improve the mixing efficiency between the powders, and after the powder in the mixer 3 is blown up, the follower plate 12 can maintain an inclined state and follow the horizontal axis 11 to make a circular motion, generate a downward pressure, and realize the collision between the upper powder and the lower powder, and the follower plate 12 rotates to generate a spiral downward pressure, so that the airflow in the mixer 3 is disturbed, and the mixing degree between the powders is further improved.

[0050] Specifically as follows: the power assembly is used to drive the mixer 3 and the energy storage assembly to move alternately, and the power assembly includes a support plate 2 installed on the base 1, the support plate 2 is rotatably connected to the mixer 3, and a driving device 4 is installed on the support plate 2, and the output shaft of the driving device 4 is connected to the Maltese cross movement structure arranged on the support plate 2, and the Maltese cross movement structure is connected to the mixer 3 through a No. 1 belt 7, and is connected to the energy storage assembly through a No. 2 belt 9.

[0051] The mixer 3 with a hollow structure inside is rotatably mounted on the base 1;

[0052] The rotating shaft 10 is rotatably installed in the mixer 3 , and a retardation chamber 1001 is disposed at one end of the rotating shaft 10 . A through hole 1002 opening obliquely upward is disposed at a side of the retardation chamber 1001 .

[0053] The Maltese cross movement structure includes a driving wheel 5, a first driven wheel 6 and a second driven wheel 8 rotatably mounted on the support plate 2, the driving wheel 5 is connected to the output shaft of the driving device 4, and the driving wheel 5 is adapted to the first driven wheel 6 and the second driven wheel 8.

[0054] When in use, the powder generated from waste tires and the desulfurization auxiliary agent powder are poured into the mixer 3 in a predetermined proportion, and the driving device 4 is started. The driving device 4 can drive the driving wheel 5 to rotate when working, and drive the No. 1 driven wheel 6 and the No. 2 driven wheel 8 to rotate through the driving wheel 5. Specifically, when the No. 1 driven wheel 6 rotates in coordination with the driving wheel 5, the No. 2 driven wheel 8 is in a locked state. At this time, the mixer 3 can rotate one circle according to the No. 1 driven wheel 6. At this time, the powder in the mixer 3 can reciprocate once at both ends of the mixer 3, so that the powder can be pre-mixed first, and when the No. 2 driven wheel 8 rotates in coordination with the driving wheel 5, the No. 1 driven wheel 6 is in a locked state. In this state, the position stability of the mixer 3 can be guaranteed, and the connecting component can be coaxial with the rotating shaft 10, so that when the connecting component is in action, it can be inserted into the hysteresis chamber 1001, thereby improving the stability of the connecting component when it cooperates with the hysteresis chamber 1001.

[0055] See also Figure 1 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , the energy storage component is connected to the trigger component, the energy storage component can passively store potential energy and actively release potential energy, and when the energy storage component actively releases potential energy, it will drive the trigger component to act;

[0056] The energy storage assembly includes two transmission wheels 17 rotatably mounted on the base 1, wherein the rotating shaft of one of the transmission wheels 17 is connected to the second belt 9, a transmission belt 18 is sleeved between the two transmission wheels 17, and two convex shafts 19 are symmetrically arranged on the side of the transmission belt 18;

[0057] The energy storage assembly further includes two cross bars 21 disposed on the base 1, and an abutment member 20 adapted to the convex shaft 19 is slidably mounted on the cross bars 21. A second spring 22 is also sleeved on the cross bars 21, and one end of the second spring 22 is connected to the end of the cross bar 21, and the other end is connected to the abutment member 20;

[0058] The connecting assembly is arranged on the base 1, and the connecting assembly can connect the hysteresis chamber 1001 with the trigger assembly when the energy storage assembly is actuated. The connecting assembly includes a connecting pipe 34 rotatably mounted on the base 1, the interior of the connecting pipe 34 is a hollow structure, and a side groove 3401 is arranged on the side wall of the connecting pipe 34, and a connecting sleeve 33 sealingly and slidably mounted on the connecting pipe 34 can be inserted into the hysteresis chamber 1001, and a connecting head 35 is also sealed and rotatably mounted on the connecting pipe 34, and compressed air entering the connecting head 35 can enter the interior of the connecting pipe 34 through the side groove 3401;

[0059] The connecting assembly further comprises a horizontal rod 23 with a collar 2301 formed at one end, and the collar 2301 is rotatably fitted with an annular groove 3301 provided on the connecting sleeve 33;

[0060] The connecting assembly further comprises a guiding structure connected to the abutment member 20, wherein the guiding structure comprises a connecting plate 25 slidably arranged through the abutment member 20, and a follower sleeve 24 is arranged at one end of the connecting plate 25, and the follower sleeve 24 is slidably fitted with the horizontal rod 23;

[0061] The guide structure further comprises a guide plate 27 arranged on the base 1 , and an inclined groove 2701 and a horizontal groove 2702 are arranged on the guide plate 27 . The groove wheel 26 arranged at the other end of the connecting plate 25 can roll in the inclined groove 2701 and the horizontal groove 2702 .

[0062] When the second driven wheel 8 rotates, it can drive the transmission wheel 17 connected thereto to rotate, and make the transmission belt 18 sleeved between the two transmission wheels 17 rotate, wherein the transmission belt 18 can be regarded as composed of two straight segments and two circumferential segments, the two straight segments are parallel and the ends are connected by the circumferential segments, so that when the transmission wheel 17 rotates, the convex shaft 19 can perform horizontal movement and circular movement (which can be regarded as lifting movement), and in the initial state, one of the convex shafts 19 is located on the side of the abutment 20 away from the second spring 22, and the convex shaft 19 is located in the straight segment position of the lower layer of the transmission belt 18, so that When the cam 19 follows the movement of the transmission belt 18, it can abut against the abutment 20 and drive the abutment 20 to move along the length direction of the cross bar 21. At this time, the No. 2 spring 22 can be compressed and store elastic potential energy. At the same time, the abutment 20 drives the groove wheel 26 to move horizontally. At this time, the groove wheel 26 moves upward along the inclined groove 2701, and when the groove wheel 26 moves into the horizontal groove 2702, the connecting sleeve 33 is driven upward by the follower sleeve 24 and the horizontal rod 23 and inserted into the hysteresis chamber 1001. At this time, the connecting sleeve 33 and the hysteresis chamber 1001 are in a sealed connection state.

[0063] As the cam 19 moves, the cam 19 will move to the circumferential section on the other side of the transmission belt 18. At this time, the cam 19 will make a circular motion and slide relative to the abutment 20. After the cam 19 is separated from the abutment 20, the No. 2 spring 22 will release its elastic potential energy and actively drive the abutment 20 to move in the opposite direction. At this time, the abutment 20 drives the trigger assembly to act.

[0064] Among them, the height of the upper end of the abutment 20 is between the rotating shaft of the transmission wheel 17 and the lower edge of the transmission wheel 17, and after the cam 19 is separated from the abutment 20, the second driven wheel 8 stops moving. At this time, the other cam 19 is in the position of the original cam 19 and is converted, so that when the second driven wheel 8 rotates next time, the abutment 20 can be driven again by the cam 19 to repeat the above process.

[0065] Through the above-mentioned arrangement, during the cooperation between the convex shaft 19 and the abutment 20, the No. 2 spring 22 can be driven to store elastic potential energy, so that the trigger assembly can be driven to operate when the No. 2 spring 22 actively releases the elastic potential energy. When the abutment 20 operates, the connecting sleeve 33 can be inserted into the hysteresis chamber 1001 through the cooperation of the groove wheel 26 and the inclined groove 2701 and the horizontal groove 2702, so that when the trigger assembly is operated, compressed gas is pumped into the hysteresis chamber 1001 through the connecting sleeve 33 and the connecting pipe 34.

[0066] See also Figure 1 , Figure 6 , Fig. 9 A connecting rod 14 is slidably installed in the retardation chamber 1001, one end of the connecting rod 14 is connected to a spring 13 arranged in the retardation chamber 1001, and the other end is connected to a sealing plug 15, and the sealing plug 15 is adapted to a convex ring 1003 formed in the retardation chamber 1001. In the initial state, the sealing plug 15 fits with the convex ring 1003, so that one end of the retardation chamber 1001 is in a blocked state, which prevents the powder in the mixer 3 from escaping from the retardation chamber 1001 to the outside when the mixer 3 rotates, thereby improving the sealing performance;

[0067] The trigger assembly is disposed on the base 1, and the trigger assembly can deliver compressed gas toward the hysteresis chamber 1001 and drive the rotating shaft 10 to rotate;

[0068] The trigger assembly includes a pump cylinder body 29 installed on the base 1, the pump cylinder body 29 is connected to the connecting head 35, and a sealing plug 30 is sealingly and slidably installed in the pump cylinder body 29, and a telescopic shaft 31 passing through the pump cylinder body 29 is connected to the sealing plug 30, and a differential groove 3101 is provided at one end of the telescopic shaft 31 away from the sealing plug 30, and the differential groove 3101 is slidably connected to the connecting bracket 28 connected to the abutment 20.

[0069] When the No. 2 spring 22 releases its elastic potential energy and actively drives the abutment 20 to reset, the abutment 20 can drive the telescopic shaft 31 and the sealing plug 30 to move toward the inside of the pump cylinder body 29, compressing the air in the pump cylinder body 29, so that the air is pressed into the hysteresis chamber 1001 through the connecting head 35, the connecting sleeve 33 and the connecting pipe 34, and as the pressure in the hysteresis chamber 1001 increases, the sealing plug 15 can be pushed open and then separated from the convex ring 1003. At this time, the compressed gas escapes through the through hole 1002 and directly acts on the powder deposited at the bottom of the mixer 3 to blow up the powder at the bottom of the mixer 3 and move the powder to the upper space of the mixer 3. In this process, the powder moves freely, so that the two powders can be further mixed.

[0070] It should be noted that an inclined guide surface is provided inside one end of the mixer 3 close to the through hole 1002, which cooperates with the through hole 1002 with an opening inclined upward to blow up the powder in the mixer 3 as much as possible, thereby improving the mixing efficiency between the powders.

[0071] It is worth noting that when the cam 19 acts on the abutment 20 and causes the abutment 20 to move toward the No. 2 spring 22 to the end of the stroke, the connecting bracket 28 abuts against the side wall of the differential groove 3101 away from the sealing plug 30, so that after the cam 19 is separated from the abutment 20, the abutment 20 can move quickly in the direction away from the No. 2 spring 22 without load. At this time, the connecting bracket 28 slides in the differential groove 3101, so that the connecting bracket 28 has an accelerated motion state in this state. When the connecting bracket 28 abuts against the other side of the differential groove 3101, the two can drive the telescopic shaft 31 and the sealing plug 30 to move quickly through collision, and the air in the pump cylinder body 29 is quickly compressed, so that the air generates an explosive airflow when escaping the through hole 1002, thereby further ensuring that the powder in the mixer 3 can be blown up.

[0072] In detail, the rotating shaft on one side of the mixer 3 is connected to the interior thereof and is connected to a pressure valve 301, which is connected to an external transfer box (not shown in the figure), and the external transfer box is connected to a one-way valve on the pump cylinder body 29. In the initial state, the interior of the external transfer box is evacuated, and when the compressed gas is pumped into the mixer 3, the pressure in the mixer 3 will increase. When the pressure increases to a predetermined value, the pressure valve 301 is turned on, allowing the gas to enter the external transfer box. At the same time, the abutment 20 drives the sealing plug 30 to move in the direction of the No. 2 spring 22, and a negative pressure will be generated in the pump cylinder body 29. The negative pressure can be used to draw the gas in the external transfer box into the pump cylinder body 29, and then pumped into the mixer 3, so as to achieve air pressure balance and avoid leakage caused by excessive internal pressure of the mixer 3 as the mixing proceeds.

[0073] Furthermore, the setting of the above-mentioned sealing plug 15 and the convex ring 1003, on the one hand, can make one end of the hysteresis chamber 1001 in a blocked state, thereby preventing the powder in the mixer 3 from escaping from the hysteresis chamber 1001 to the outside when the mixer 3 rotates, thereby improving the sealing performance; on the other hand, it plays the role of a one-way valve, so that when the abutment 20 drives the sealing plug 30 to move in the direction of the No. 2 spring 22, the negative pressure can be used to draw the gas in the external transfer box into the pump cylinder body 29, rather than drawing the gas in the mixer 3 into the pump cylinder body 29.

[0074] Through the above arrangement, when the connecting bracket 28 is actuated, the sealing plug 30 can be driven to move quickly, so that the compressed air can explosively escape from the through hole 1002. Under the cooperation of the inclined guide surface and the through hole 1002 with the opening inclined upward, the powder in the mixer 3 can be blown up as much as possible, thereby improving the mixing efficiency between the powders.

[0075] See also Figure 3 , Figure 5 , Figure 6 , the trigger assembly further comprises a ratchet 16 coaxially connected to the rotating shaft 10 and a ratchet plate 32 connected to the abutment member 20, the ratchet plate 32 being adapted to the ratchet 16;

[0076] The follower structure is disposed on the rotating shaft 10, and when the rotating shaft 10 rotates, the follower structure can generate downward pressure on the dust placed in the mixer 3;

[0077] The follower structure includes a transverse axis 11 connected to the rotating shaft 10 , on which a follower plate 12 is rotatably mounted, a through slot 1201 is formed at the rotating shaft of the follower plate 12 , and a side wall of the through slot 1201 is adapted to a limit block 1101 arranged on the transverse axis 11 .

[0078] When the abutment 20 moves driven by the No. 2 spring 22, the connecting bracket 28 will first drive the sealing plug 30 to move, and after the powder in the mixer 3 is blown up by injecting compressed air into the retardation chamber 1001, the ratchet plate 32 will engage with the ratchet 16 to rotate the rotating shaft 10 and drive the horizontal shaft 11 to make a circular motion. When the horizontal shaft 11 makes a circular motion, due to air resistance, the follower plate 12 will deflect relative to the horizontal shaft 11, and when the side wall of the through groove 1201 abuts against the limit block 1101, the follower plate 12 stops deflecting and follows the horizontal shaft 11 in a tilted state to make a circular motion. At this time, the follower plate 12 can generate downward pressure during rotation, thereby realizing the collision of the upper powder and the lower powder. At the same time, the rotation of the follower plate 12 generates spiral downward pressure, which disturbs the airflow in the mixer 3 and further improves the mixing degree between the powders.

[0079] A method for mixing waste tire powder and a desulfurization aid using the waste tire powder mixing device for processing recycled rubber comprises the following steps:

[0080] Step 1: Pour the powder generated from waste tires and the desulfurization auxiliary powder into the mixer 3 according to a predetermined ratio;

[0081] Step 2: Control the action of the power component, the power component will first rotate the mixer 3 for one circle, then drive the energy storage component to passively store energy potential energy, and make the connecting component move, so that the hysteresis chamber 1001 is connected to the trigger component;

[0082] Step 3: After the energy storage component completes passive storage of potential energy, the energy storage component will actively release the potential energy.
