DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] Embodiment 1:

[0037] Reference Figure 1-Figure 7A rubber desulfurization, plasticizing and grading granulation device comprises a desulfurization tank 1 and a granulator 3, and is also provided with a driving motor 2 connected to the granulator 3. The desulfurization tank 1 and the granulator 3 are both conventional means in the prior art. The specific structure can refer to the technical scheme in the prior art, so it is not repeated here. It also includes: a discharge port 5 and an exhaust pipe 6 connected to the desulfurization tank 1, wherein the exhaust pipe 6 is provided with a dust removal mechanism 10 and a dehumidification mechanism 12 for dust removal and dehumidification of the exhaust gas generated by desulfurization. In addition, the dehumidification mechanism 12 is connected to the dust removal mechanism 10 through a pipeline; a feed hopper 7 is arranged on the granulator 3, and a connecting pipe 8 is connected between the feed hopper 7 and the discharge port 5, wherein a driving unit is arranged between the outer wall of the desulfurization tank 1 and the outer wall of the feed hopper 7, and a screening unit is arranged inside the feed hopper 7. The dehumidification mechanism 12 can drive part of the structure of the screening unit to rotate through the driving unit, so as to screen impurities in the rubber.

[0038] Reference Figure 3 and Figure 6 The dust removal mechanism 10 includes a dustproof plate 101 slidably connected to the exhaust pipe 6, a waterproof ring 102 is fixedly connected to the side of the exhaust pipe 6 close to the dustproof plate 101, multiple groups of connecting cylinders 103 and first springs 104 are fixedly connected between the waterproof ring 102 and the dustproof plate 101, the first spring 104 is sleeved on the outside of the connecting cylinder 103, a dust removal port 105 is opened on the side of the bottom of the exhaust pipe 6 close to the dustproof plate 101, and a dust collecting box 106 is detachably connected to the side of the exhaust pipe 6 close to the dust removal port 105, wherein the dustproof plate 101 is in contact with the inner wall of the exhaust pipe 6, the dust removal port 105 is inclined, the waterproof ring 102 is inclined, and a cleaning mechanism is provided on the side of the exhaust pipe 6 close to the dustproof plate 101 for cleaning the dustproof plate 101.

[0039] When the exhaust gas flows in the exhaust pipe 6, the dustproof plate 101 can intercept the dust in the exhaust gas, and because the dustproof plate 101 is close to the desulfurization tank 1, the temperature is relatively high, and the water vapor in the exhaust gas will not be liquefied. In addition, the liquefied water will not contact the dustproof plate 101 under the action of the waterproof ring 102, that is, the dust will not be wet and adsorbed on the dustproof plate 101. When intercepting dust, the extension and contraction of the connecting cylinder 103 can drive the dustproof plate 101 to vibrate, thereby avoiding the situation where dust blocks the dustproof.

[0040] Reference Figure 6The cleaning mechanism includes an air motor 107 fixedly connected to the outer wall of the exhaust pipe 6, the output end of the air motor 107 extends to the inside of the exhaust pipe 6, a fixed plate 108 is fixedly connected to the inner wall of the exhaust pipe 6, a horizontal axis 109 is rotatably connected to the fixed plate 108, a linkage bevel gear set 1010 is arranged between the horizontal axis 109 and the output end of the air motor 107, a scraper 1011 is fixedly connected to one end of the horizontal axis 109 away from the bevel linkage bevel gear set 1010, and the scraper 1011 is in contact with the dustproof plate 101.

[0041] After the rubber devulcanization is completed, when the rubber is granulated, the pneumatic motor 107 is driven to rotate, and the scraper 1011 is driven to rotate on the dust plate 101 through the linkage bevel gear set 1010, so as to scrape off the dust adhering to the dust plate 101, and finally collect it in the dust box 106, which can not only improve the purification efficiency of the exhaust gas, but also facilitate the recycling of the dust, while reducing the damage of the dust to the environment and human body.

[0042] Reference Figure 3 and Figure 7 The dehumidification mechanism 12 includes a mist blocking plate 121 fixedly connected to the inner wall of the exhaust pipe 6, a drain port 122 is provided on the side of the bottom of the exhaust pipe 6 close to the mist blocking plate 121, a transition box 123 is detachably connected to the side of the outer wall of the exhaust pipe 6 close to the drain port 122, a baffle 124 is rotatably connected to the inside of the transition box 123, a sealing member 125 is fixedly connected to the side of the transition box 123 close to the baffle 124, and a second elastic member 125 is fixedly connected between the baffle 124 and the bottom of the transition box 123. Spring 126, the bottom of the transition box 123 is fixedly connected with a compression cylinder 127, wherein the drain port 122 is located below the mist blocking plate 121, the seal 125 is fitted with the baffle 124, the compression cylinder 127 is connected to part of the connecting cylinder 103 through a pipeline, and also includes a condenser 11 arranged on the outer wall of the exhaust pipe 6, the condenser 11 is located between the waterproof ring 102 and the mist blocking plate 121, and an exhaust purifier 13 is arranged at one end of the exhaust pipe 6 away from the desulfurization tank 1.

[0043] It needs to be explained that the specific structure of the mist blocking plate 121 and the condenser 11 can refer to the technical solutions in the prior art, and those skilled in the art can know it, so it will not be elaborated here. Since the exhaust gas is in a flowing state when passing through the condenser 11, the water vapor close to the side of the condenser 11 can quickly condense into water droplets, while the water vapor away from the condenser 11 can be in a mist state and continue to flow with the exhaust gas. The mist blocking plate 121 can intercept and collect the mist water, and finally collect it into the transition box 123. In addition, when the water is collected, it will first fall onto the baffle 124, so that the water condenses into a ball to reduce the evaporation of water. When the water on the baffle 124 reaches a certain amount, it flows to the bottom of the transition box 123 and is finally collected in the water storage tank 14. At the same time, the gas is intermittently compressed by the compression cylinder 127 and passed into the connecting cylinder 103, driving the connecting cylinder 103 to extend and contract intermittently. In addition, the type of the exhaust purifier 13 is not limited, and the exhaust gas can be treated by adsorption, combustion, or absorption.

[0044] Reference Figure 2 and Figure 5 The driving unit includes a water storage tank 14 fixedly connected to the outer wall of the desulfurization tank 1, the top of the water storage tank 14 is connected to the transition box 123 through a pipeline, a turbine 16 is fixedly connected to the outer wall of the feed hopper 7, and a connecting pipe 15 is connected between the turbine 16 and the water storage tank 14, wherein the output end of the turbine 16 extends to the inside of the feed hopper 7, and the outer wall of the feed hopper 7 and the output shaft of the turbine 16 are fixedly connected with a first linkage wheel 17, and a first belt 18 is sleeved between the two sets of first linkage wheels 17.

[0045] It should be explained that since the height of the desulfurization tank 1 is much higher than the height of the granulator 3, the water in the water storage tank 14 has a large gravitational potential energy. When the water flows to the turbine 16 through the connecting pipe 15, it can drive the turbine 16 to rotate and recover the water through the outlet of the turbine 16. The specific structure of the turbine 16 can refer to the technical solutions in the prior art, which can be known by technicians in this field and will not be elaborated here. In addition, the flow of water can be controlled by setting a valve in the connecting pipe 15 (since the desulfurization tank 1 is in a working state when the granulator 3 is working, it is impossible to achieve water flow while collecting water).

[0046] Reference Figure 4The screening unit includes a plurality of groups of vibrating cylinders 20 fixedly connected to the inside of the feed hopper 7, a sieve plate 21 that fits the inner wall of the feed hopper 7 is fixedly connected to the top of the vibrating cylinder 20, a slag discharge port 26 is provided on the side of the feed hopper 7 close to the sieve plate 21, and a collecting frame 27 is fixedly connected to the side of the feed hopper 7 close to the slag discharge port 26, wherein a cam 19 is fixedly connected to the shaft of the turbine 16 extending to the inside of the feed hopper 7, and the cam 19 is located at the center below the sieve plate 21, and the vibrating cylinder 20 has Elasticity, the vibrating cylinder 20 is connected with part of the connecting cylinder 103 and the pneumatic motor 107 through a pipeline, and also includes an equalizing roller 22 and a slag discharge roller 23 rotatably connected to the inside of the feed hopper 7, and a second interlocking wheel 24 is fixedly connected to the equalizing roller 22 and the slag discharge roller 23, and a second belt 25 is sleeved between the two groups of second interlocking wheels 24, wherein the equalizing roller 22 is connected to the axis of one group of first interlocking wheels 17, the equalizing roller 22 is close to the connecting pipe 8, and the slag discharge roller 23 is close to the slag discharge port 26.

[0047] Since the rubber after desulfurization may contain impurities, the rubber needs to be screened before granulation. When the turbine 16 rotates, it drives the cam 19 and the dividing roller 22 to rotate, and then drives the slag discharge roller 23 to rotate through the second linkage wheel 24 and the second belt 25. Among them, when the rubber enters the feed hopper 7 through the connecting pipe 8, the dividing roller 22 can divide the rubber evenly to avoid the accumulation of rubber on the screen plate 21, thereby improving the screening efficiency of the rubber. At the same time, the cam 19 drives the screen plate 21 to vibrate, further improving the screening efficiency of the rubber, so as to facilitate the granulation of the rubber. It should be explained that the impurities in the rubber will stay on the screen plate 21, and contact with the dividing roller 22 as the screen plate 21 vibrates. Under the action of centrifugal force, the impurities are thrown to the slag discharge roller 23 (there is a certain distance between the dividing roller 22 and the slag discharge roller 23 and the screen plate 21, which can reduce the amount of rubber thrown out), and then the impurities are thrown into the collecting frame 27 by the slag discharge roller 23 to collect the impurities.

[0048] Reference Figure 1-Figure 2 The top of the desulfurization tank 1 is connected with a feed port 4, which is connected by a flange and is used to seal the rubber during desulfurization. A control valve 9 is provided on the connecting pipe 8 to control the speed of adding the rubber into the feed hopper 7 after the desulfurization is completed.

[0049] When desulfurizing rubber, rubber powder and desulfurizing agent need to be added into the desulfurization tank 1 through the feed port 4, and the feed port 4 is sealed to prevent the waste gas generated by the rubber during the desulfurization process from being directly discharged into the air.

[0050] Embodiment 2:

[0051] A method for using a rubber desulfurization plasticizing and grading granulation device comprises the following steps:

[0052] Step 1: adding the crushed rubber into the desulfurization tank 1, and desulfurizing the rubber through the desulfurization tank 1;

[0053] During the process of rubber desulfurization, the desulfurization tank 1 is in a sealed state;

[0054] Step 2: During the desulfurization process, the waste gas generated enters the waste gas pipe 6, and the dust in the waste gas is first processed and collected by the dust removal mechanism 10;

[0055] The dust in the exhaust gas is intercepted on the dust removal mechanism 10 during the flow, and part of the dust is caused to fall off from the dust plate 101 by vibration and collected in the dust box 106;

[0056] Step 3: As the exhaust gas flows in the exhaust pipe 6, the water vapor in the exhaust gas is processed and collected by the dehumidification mechanism 12, and during the collection process, the dust removal mechanism 10 is driven to vibrate, thereby accelerating the collection of dust and preventing the dust removal mechanism 10 from being blocked;

[0057] When the exhaust gas passes through the condenser 11, the water vapor therein can be liquefied, and the water is collected by the dehumidification mechanism 12. When collecting the water, the intermittent compressed gas is transported to the dust removal mechanism 10, driving the dust plate 101 to vibrate, accelerating the shedding of dust, thereby ensuring the stability of the exhaust gas flow;

[0058] Step 4: After desulfurization is completed, the rubber is added to the feed hopper 7, and the collected water drives the screening unit to vibrate through the driving unit, while collecting impurities in the rubber;

[0059] By collecting the gravitational potential energy of water, the screening unit is driven to vibrate, which speeds up the screening of rubber and improves the efficiency of rubber granulation;

[0060] Step 5: While screening the rubber, the dust removal mechanism 10 can be driven to rotate, and the dust adhering to the dust removal mechanism 10 can be thoroughly cleaned to facilitate the subsequent treatment of the exhaust gas.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
