Description

Technical Field

[0001] The invention relates to the field of mixing equipment, in particular to a linkage type double-shaft coal mixer. Background Art

[0002] The double-shaft mixer is a machine used to process materials. It is mostly used to process coal, tar residue and other materials for mixing and processing, so it is also called a coal mixer. It uses the spiral blades of the stirring shaft to rotate in the opposite direction to mix and stir the materials. Mixing is one of the important links in the production and processing of ingredients. The principle of the double-shaft mixer is fast and thorough mixing. Compared with ordinary horizontal mixers, it and the buffer occupy less space, have low unit power consumption, and are convenient for inspection and maintenance. However, a large amount of dust and coal ash will still be generated during the operation of the coal mixer, and even fine coal ash will escape from the mixer, which will cause pollution to the external environment. For this reason, we need a new type of linkage double-shaft coal mixer.

[0003] On this basis, after searching the patent network, the Chinese patent application number 202011539536.2 discloses a noise-proof paddle-type twin-shaft mixer, including The present invention discloses a noise-proof paddle-type twin-shaft mixer, which relates to the field of twin-shaft mixers, including a box body and a feed port, a plurality of feed ports are arranged above the box body, the feed ports penetrate the upper shell wall of the box body, a stirring tube is arranged below the feed port, a stirring mechanism is arranged inside the stirring tube, a mixing box is arranged at one end of the stirring tube away from the feed port, a mixing mechanism is arranged inside the mixing box, and a sponge pad is used to clean the shell wall of the mixing box, thereby reducing the collision between the stirring mechanism and the device itself, and does not reduce the mixing range, reducing the generation of noise and the loss of the device itself, which is suitable for large-scale promotion;

[0004] It can be seen that there are shortcomings in the above patent application: the existing double-shaft mixer has a relatively simple structure and function, and does not have a screening effect during the material stirring and mixing process. If large lumps of material are discharged from one side of the device, the discharge port is prone to blockage. The process of cleaning the discharge port requires additional manpower, which affects work efficiency, affects the use effect of the device, and reduces the work efficiency of the equipment.

[0005] In view of the above problems, a linkage double-axis coal mixer is proposed. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. A linkage double-shaft coal mixer proposed by the present invention throws the raw materials to be processed into the mixer assembly through the feed hopper, and the materials fall into the inner cavity of the mixing chamber. The user can observe the internal situation of the mixer assembly through the transparent visual window, and the inspection door is provided to facilitate opening and maintenance of the inside of the mixer assembly; when all the raw materials have been fed into the mixing chamber, the first motor is turned on and rotated, and the first motor drives the first roller to rotate. At this time, the third roller fixedly connected to the first roller rotates, and due to the transmission of the second belt, the two groups of third rollers rotate at the same time, and at the same time, the two groups of mixing shaft components inside the mixing chamber rotate, and the outer periphery of the mixing shaft components is provided with spiral blades. The two groups of mixing shaft components and the multiple groups of spiral blades rotate to mix and stir the materials in the mixing chamber, so that the raw materials are mixed quickly and thoroughly, and the working efficiency of the device is improved;

[0019] 2. After the materials in the mixing chamber have been completely mixed, the material port at the bottom of the mixing chamber is opened, and the materials leave the mixing chamber and fall on the top surface of the screening mesh plate. The screening mesh plate screens the materials after mixing, and the evenly mixed materials fall on the shaking receiving plate through the screening mesh plate. In order to mix evenly, the materials with large lumps will remain on the top surface of the screening mesh plate. This operation can facilitate the screening of the materials after mixing. The rotation of the first motor will drive the first roller to rotate, and the first roller will drive the second roller and the cam to rotate due to the rotation of the first belt. The cam rotates at the bottom of the shaking receiving plate, which will drive the shaking receiving plate to vibrate up and down reciprocatingly. At this time, multiple groups of spring telescopic rods perform telescopic movements at the same time, and the spring telescopic rods support the shaking receiving plate. The shaken shaking receiving plate will slide the qualified materials down along the guide plate, and then leave the mixer assembly from the guide plate on one side of the guide plate, and the user can then collect the processed materials; the reciprocating shaking of the shaking receiving plate is to speed up the material discharge;

[0020] 3. If the material left on the top of the screening mesh plate is a large lump or unevenly mixed material, the user can start the hydraulic cylinder to extend the hydraulic cylinder, which will drive the push plate component to extend. The push plate component will slide horizontally along the top of the screening mesh plate. The push plate component will scrape the unqualified material left on the top of the screening mesh plate and scrape the material into the collection box assembly for unified collection. After the device is finished working, the user can pull the collection box assembly out from one side of the mixer assembly, which is convenient for the user to uniformly handle the unqualified materials.

[0021] 4. Since there will be flying dust and coal ash during the whole mixing and feeding process of the device, in order to prevent these dust and coal ash from flying out of the mixer assembly and polluting the external environment, the user can turn on the dust suction component working mode, start the dust suction mode of the first dust suction head component and the second dust suction head component, and the two sets of dust suction components absorb the dust and coal ash in the device, and send them to the cavity box through the hose for unified collection. When the device is working, the stirring shaft component will rotate, and the stirring shaft component will drive the rotating rod, the second bevel gear, the first bevel gear and the reciprocating screw to rotate at the same time to perform linkage work. Since the through cavity is slidably connected to the inside of the mixer assembly, The rotation of the reciprocating screw rod will drive the through cavity and the second dust suction head component to make up and down reciprocating motion along the reciprocating screw rod, thereby making the second dust suction head component move up and down inside the device, thereby more quickly absorbing and collecting the dust and coal ash generated inside the device, thereby accelerating the working efficiency of the dust suction component. Finally, after the device is finished working, the pull-out box can be slid out to clean the impurities therein. The user can also open the inspection door to clean and maintain the inside of the mixer component. The dust suction component can reduce the flying of dust and coal ash generated in the device and avoid the impact of pollution on the external environment. The entire device has linkage and high working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] To sum up the working principle: the invention proposes a linkage double-axis coal mixer, in which the raw materials to be processed are thrown into the mixer component 1 through the feed hopper 2, and the materials fall into the inner cavity of the stirring chamber 13. The transparent visual window 12 allows the user to observe the internal situation of the mixer component 1, and the inspection door 11 is provided to facilitate opening and maintenance of the inside of the mixer component 1; when all the raw materials have been fed into the stirring chamber 13, the first motor 16 is turned on and rotated, and the first motor 16 drives the first roller 17 to rotate. At this time, the third roller 141 fixedly connected to the first roller 17 rotates, and due to the transmission of the second belt 142, the two groups of third rollers 141 rotate at the same time, and at the same time, the two groups of stirring shaft components 14 inside the stirring chamber 13 rotate, and the outer periphery of the stirring shaft component 14 is provided with spiral blades. The two groups of stirring shaft components 14 and the multiple groups of spiral blades rotate to mix and stir the materials in the stirring chamber 13, so that the raw materials are mixed quickly and thoroughly, thereby improving the working efficiency of the device;

[0042] After the materials in the stirring chamber 13 have been stirred and mixed completely, the material inlet at the bottom of the stirring chamber 13 is opened, and the materials leave the stirring chamber 13 and fall on the top surface of the screening mesh plate 37. The screening mesh plate 37 screens the stirred materials, and the evenly stirred materials will fall on the shaking receiving plate 34 through the screening mesh plate 37. In order to stir evenly, the materials with large lumps will remain on the top surface of the screening mesh plate 37. This operation can facilitate the screening of the stirred materials. The rotation of the first motor 16 will drive the first roller 17 to rotate, and the first roller 17 will bring the first belt 18 to rotate. The second rotating roller 19 and the cam 191 are driven to rotate, and the cam 191 rotates at the bottom of the shaking receiving plate 34, which will drive the shaking receiving plate 34 to vibrate up and down reciprocatingly. At this time, multiple groups of spring telescopic rods 35 perform telescopic movements at the same time, and the spring telescopic rods 35 support the shaking receiving plate 34. The shaking receiving plate 34 will slide the screened qualified materials along the guide plate 33, and then leave the mixer assembly 1 from the guide plate 31 on one side of the guide plate 33, and the user can then collect the processed materials; the reciprocating shaking work of the shaking receiving plate 34 is to speed up the material discharge;

[0043] The material remaining on the top surface of the screening mesh plate 37 is a large lump and is not mixed evenly. The user can start the hydraulic cylinder 32 to extend the hydraulic cylinder 32, which will drive the push plate component 36 to extend. The push plate component 36 slides horizontally along the top of the screening mesh plate 37.

After the device is finished working, the user can pull the collection box component 5 out from one side of the mixer component 1, which is convenient for the user to uniformly process the unqualified materials.

[0044] Since there will be flying dust and coal ash during the entire stirring and feeding process of the device, in order to prevent the dust and coal ash from flying out of the mixer component 1 and polluting the external environment, the user can turn on the working mode of the dust suction component 4, start the dust suction mode of the first dust suction head component 43 and the second dust suction head component 46, and the two sets of dust suction components absorb the dust and coal ash in the device and send them to the cavity box 41 through the hose for unified collection. When the device is working, the stirring shaft component 14 will rotate, and the stirring shaft component 14 will drive the rotating rod 49, the second bevel gear 48, the first bevel gear 47 and the reciprocating screw 44 to rotate at the same time to perform linkage work, and since the through cavity 45 is slidably connected to the inside of the mixer component 1 The rotation of the reciprocating screw 44 will drive the through cavity 45 and the second dust suction head component 46 to reciprocate up and down along the reciprocating screw 44, so that the second dust suction head component 46 can move up and down inside the device, thereby more quickly absorbing and collecting the dust and ash generated inside the device, thereby accelerating the working efficiency of the dust suction component 4. Finally, after the device is finished working, the pull-out box 42 can be slid out to clean the impurities therein. The user can also open the inspection door 11 to clean and maintain the inside of the mixer component 1. The dust suction component 4 can reduce the flying of dust and ash generated in the device and avoid the impact of pollution on the external environment. The entire device has linkage and high working efficiency.
