Description

The moisture content of the raw materials may be too high and clumps may appear, causing the auger to fail to operate normally, which may cause the motor to overload and burn out, and even cause the risk of equipment shutdown; and, since the block raw materials have many edges and corners, when they are lifted, their edges and corners will come into contact with the auger and the inner wall of the device, causing scratches on the auger and the inner wall of the device, reducing the service life of the device.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0042] In one embodiment of the present invention, see Figure 1-Figure 2 A raw material elevator for refractory material production includes a storage box 1, a movable box 2 is movably provided at the bottom of the storage box 1, a lifting assembly 4 is connected between the storage box 1 and the movable box 2, a raw material lifting assembly 3 for lifting raw materials is provided on the storage box 1, a filtering assembly 5 for stirring and filtering is movably provided on the inside of the storage box 1, a transmission assembly 8 connected between the raw material lifting assembly 3 and the filtering assembly 5 is provided at the bottom of the storage box 1, a hot air pump 6 is provided on the outer wall of the storage box 1, and the output end of the hot air pump 6 is communicated with the inside of the storage box 1 through an air guide pipe 7.

[0043] In this embodiment, the distance between the storage box 1 and the mobile box 2 can be adjusted through the lifting component 4, so that the height of the storage box 1 and the raw material lifting component 3 can be adjusted, which can meet the lifting needs of raw materials at different heights and improve the applicability of the device. The raw materials can be stirred and filtered through the filtering component 5 to avoid the problem that the block raw materials cause wear on the raw material lifting component 3 and cause damage to the equipment, which helps to maintain the stability of raw material lifting. Through the cooperation of the hot air pump 6 and the air guide pipe 7, the raw materials can be dried to avoid the problem that the raw materials have too high water content and cannot be lifted, thereby improving the service life of the device. The raw materials in the storage box 1 can be lifted through the raw material lifting component 3, and the linkage between the raw material lifting component 3 and the filtering component 5 can be realized through the transmission component 8, thereby improving the efficiency of raw material stirring and filtering, and having the effects of height adjustment, high-efficiency filtration, effective drying, stable lifting, flexible linkage, convenient operation, and simple and practical operation.

[0044] A handle 101 and a controller 102 are installed on the outer wall of the storage box 1. The controller 102 is electrically connected to the electrical equipment. The start, stop, forward and reverse rotation of the electrical equipment can be controlled by the controller 102.

[0045] A plurality of moving wheels 201 are symmetrically mounted on the bottom of the mobile box 2. A positioning plate 202 that is in contact with the ground is movably mounted on the bottom of the mobile box 2. An electric cylinder 203 is connected between the positioning plate 202 and the bottom of the mobile box 2. A plurality of vertical poles 204 are symmetrically mounted on one side of the positioning plate 202 close to the mobile box 2. A plurality of guide cylinders 205 corresponding to the vertical poles 204 are symmetrically mounted on the bottom of the mobile box 2. The vertical poles 204 are in sliding engagement with the inner walls of the guide cylinders 205.

[0046] When the device is in working condition, the positioning plate 202 is in contact with the ground. At this time, the position of the mobile box 2 can be fixed, which is convenient for the stable lifting of the raw materials. When the position of the device needs to be moved, the electric cylinder 203 is controlled to retract upward. The electric cylinder 203 drives the positioning plate 202 to move upward by connecting with the positioning plate 202 and the vertical rod 204 and the guide cylinder 205 slidingly cooperate, thereby releasing the contact between the positioning plate 202 and the ground.

[0047] In one embodiment of the present invention, see Figure 1-Figure 3 、 Figure 5-Figure 6The raw material lifting assembly 3 includes a material guide cylinder 301 extending into the inner side of the material storage box 1, and a gap is provided between the bottom of the material guide cylinder 301 and the inner bottom of the material storage box 1.

A discharge pipe 302 is connected to one side of the top of the material guide cylinder 301, and an auger 304 is movably provided inside the material guide cylinder 301 for rotating with the bottom of the material storage box 1. A lifting motor 303 connected to the auger 304 is installed on the top of the material guide cylinder 301.

[0048] In this embodiment, since there is a gap between the material guide cylinder 301 and the bottom of the storage box 1, the raw material will fill the gap, and the lifting motor 303 drives the auger 304 to rotate. The auger 304 cooperates with the material guide cylinder 301 to lift the raw material located at the gap upward. The lifted raw material is discharged through the discharge pipe 302 to the subsequent refractory material production device to realize the lifting processing of the raw material.

[0049] In one embodiment of the present invention, see Figures 1-4 The lifting assembly 4 includes a first bidirectional screw rod 402 and a second bidirectional screw rod 403 which are respectively rotatably arranged inside the moving box 2. The first bidirectional screw rod 402 and the second bidirectional screw rod 403 are respectively located on both sides of the moving box 2.

[0050] In this embodiment, in the initial state, the distance between the storage box 1 and the moving box 2 is at its minimum. At this time, the storage box 1 and the raw material lifting assembly 3 are at their lowest point, and the angle between the two hinged plates 408 corresponding to the same first pulley 404 is at its maximum.

[0051] When the position of the material lifting assembly 3 needs to be lifted, the adjusting motor 401 drives the first bidirectional screw rod 402 to rotate clockwise, and the first bidirectional screw rod 402 drives the second bidirectional screw rod 403 to rotate synchronously by being connected to the first pulley 404, the second pulley 405 and the first synchronous belt 406.

The threaded plates 407 approach each other and the threaded plates 407 and the hinged plates 408 approach each other to reduce the angle between the two hinged plates 408. The two hinged plates 408 push the storage box 1 up by reducing the angle. The storage box 1 can meet the lifting requirements of different heights of raw materials by driving the material lifting assembly 3 to move up synchronously, thereby improving the applicability of the device;

[0054] The transmission assembly 8 includes a third pulley 801 rotatably arranged at the bottom of the material storage box 1, the third pulley 801 is connected to one end of the rotating drum 504 passing through the bottom of the material storage box 1, and the fourth pulley 803 is rotatably provided at the bottom of the material storage box 1, and the fourth pulley 803 is connected to one end of the auger 304 passing through the bottom of the material storage box 1, and the fourth pulley 803 and several third pulleys 801 are connected through the second synchronous belt 802, and the fourth pulley 803 is connected to the rotating column 804 at the bottom.

[0055] In this embodiment, the lifting motor 303 drives the auger 304 to rotate, and the auger 304 drives the fourth pulley 803 and the rotating column 804 to rotate synchronously. The fourth pulley 803 drives several second synchronous belts 802 to rotate synchronously by being connected to the second synchronous belt 802. The transmission component 80 drives the rotating drum 504 to rotate by being connected to the rotating drum 504. The rotating drum 504 stirs the raw materials stored in the storage box 1 by being connected to the stirring screen 505. The cooperation of the hot air pump 6 and the air guide pipe 7 can quickly dry the raw materials and avoid the problem of high water content in the raw materials. At the same time, the rotating drum 504 drives the stirring paddles 503 to stir the raw materials placed on the filter 501 by sliding with the movable rotating rod 502 and the movable rotating rod 502 is connected to a plurality of stirring paddles 503, so as to facilitate the rapid filtration of qualified raw materials. At the same time, the bulk raw materials can be stirred and crushed to avoid the accumulation of raw materials on the filter 501 and the resulting blockage of the filter 501.

[0056] The rotating column 804 drives the beveled ring groove 8041 to rotate synchronously, and the rotating column 804 drives the movable frame 805 to rise and fall back and forth by means of the sliding cooperation between the movable frame 805 and the beveled ring groove 8041 and the sliding cooperation between the movable frame 805 and the guide rod 806. The movable frame 805 drives the filter screen 501 to rise and fall back and forth by means of the rotation cooperation with the movable rotating rod 502, the sliding cooperation between the movable rotating rod 502 and the rotating cylinder 504, and the rotation cooperation between the movable rotating rod 502 and the filter screen 501.

[0057] Specifically, the staff puts the raw materials onto the filter screen 501, and the lifting motor 303 drives the auger 304 to rotate.

The rotating column 804 drives the movable frame 805 to rise and fall back and forth by sliding cooperation between the movable frame 805 and the oblique ring groove 8041 and the movable frame 805 and the guide rod 806.

The filter screen 501 drives the raw materials on the filter screen 501 to rise and fall synchronously by reciprocating lifting, which can realize the shaking of the raw materials and facilitate the rapid filtering and processing of the raw materials.

[0058] At the same time, the fourth pulley 803 drives several second synchronous belts 802 to rotate synchronously by being connected to the second synchronous belt 802. The second synchronous belt 802 drives the rotating drum 504 to rotate by being connected to the rotating drum 504.

The cooperation of the rotating stirring screen 505, the hot air pump 6 and the air guide pipe 7 can quickly dry the raw materials to avoid the problem of high water content in the raw materials. At the same time, the rotating drum 504 drives the stirring paddle 503 to stir the raw materials put on the filter screen 501 by sliding cooperation with the movable rotating rod 502 and the movable rotating rod 502 is connected to several stirring paddles 503, so as to facilitate rapid filtration of qualified raw materials. At the same time, the block raw materials can be stirred and crushed to avoid the accumulation of raw materials on the filter screen 501 and the clogging of the filter screen 501;

[0059] The filtered and dried raw materials will accumulate at the gap between the guide cylinder 301 and the storage box 1. The auger 304 will lift the raw materials at the gap upward by cooperating with the guide cylinder 301. The lifted raw materials will be discharged to the subsequent refractory material production device through the discharge pipe 302 to realize the lifting and processing of the raw materials.

[0060] Among them, the mesh holes in the stirring screen 505 are set as circular holes. Through the setting of the circular holes, the edges and corners of the raw materials can be reduced, the friction between the raw materials and the material guide cylinder 301 and the auger 304 can be reduced, and the service life of the device can be improved. There are at least three stirring screens 505 distributed on a single rotating cylinder 504, and at least three stirring paddles 503 distributed on a single movable rotating rod 502.
