Description

Technical Field

[0001] The invention relates to the field of non-metallic mineral processing, and more specifically to a grinding machine for producing new non-metallic mineral materials. Background Art

[0002] Non-metallic minerals refer to useful mineral resources that are not used in industry to extract metal elements. Except for a few non-metallic minerals that are used to extract certain non-metallic elements, such as phosphorus and sulfur, most non-metallic minerals are used for certain physical, chemical properties and process characteristics of their minerals or mineral aggregates (including rocks), such as the insulation of mica, the fire resistance, acid resistance, insulation, heat insulation and fiber properties of asbestos. Non-metallic minerals are mainly used as metallurgical auxiliary raw materials, chemical raw materials, and building materials. For example, talc has excellent properties such as good heat resistance, lubricity, acid and alkali resistance, insulation, and strong adsorption of oils. Clays are widely used in papermaking, chemical, pharmaceutical, military, ceramics, paint, rubber and other industrial sectors.

[0003] In the process of grinding non-metallic minerals, the prior art uses blades for crushing, which will cause the blades to generate a large impact force when contacting the non-metallic minerals, which will not only cause the blades to be chipped and damaged, but also cause the non-metallic minerals to splash and damage the internal devices. In addition, a large amount of dust particles will escape during the crushing and transportation process, thereby polluting the working environment and affecting the respiratory health of personnel. In addition, the blocked filter cannot be cleared in time, resulting in a significant reduction in screening efficiency, affecting the grinding effect and output quality of the non-metallic minerals.

[0004] Therefore, a pulverizer for producing new non-metallic mineral materials is proposed to improve the above problems. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a grinding mill for the production of non-metallic mineral new materials, which can fully grind and crush non-metallic minerals, reduce the possibility of mineral splashing and hitting internal devices during the crushing process, and can perform protective collection of dust particles in different ranges during crushing and discharging and conveying, and can also clear blocked filters in time, thereby ensuring the grinding efficiency and quality of the production of non-metallic mineral new materials.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A grinding machine for producing new non-metallic mineral materials comprises a grinding box, an upper hopper is fixedly installed on the upper end of the grinding box, a material guide box is arranged at the bottom of the grinding box, a plurality of support rods are fixedly connected to the bottom of the material guide box, a bottom of the plurality of support rods is fixedly connected to a bottom platform, a surrounding frame is fixedly installed on the side wall of the grinding box, an inner wall of one side of the surrounding frame is fixedly connected to a motor, one end of the output shaft of the motor is fixedly connected to a rotating shaft, a grinding roller 1 is fixedly provided on the outside of the rod body of the rotating shaft, and a transmission shaft is rotatably connected to the other end of the top between the inner walls of both sides of the grinding box, a grinding roller 2 is fixedly connected on the outside of the rod body of the transmission shaft, a gear 1 is keyed to the outside of the rod body of the rotating shaft, a gear 2 is keyed to the outside of the rod body of the transmission shaft, the gear 1 and the gear 2 are meshed and connected, and a plurality of roller teeth are arranged on the surfaces of the grinding roller 1 and the grinding roller 2; non-metallic minerals are put into the upper hopper, and at this time, the motor controls the gear The plate rotates to a vertical state to ensure smooth feeding of non-metallic minerals, and the non-metallic minerals then fall to roller one and roller two. The control motor drives the baffle to rotate to a horizontal state, and then the motor is started to drive roller one and roller two to rotate through the meshing of gear one and gear two, so that the non-metallic minerals are fully crushed and crushed. The raised roller teeth can effectively prevent the non-metallic minerals from directly colliding with roller one, thereby causing depressions and pits on the surface of roller one, and then causing gaps between the rollers, making it impossible to tightly press and crush the non-metallic minerals, while ensuring sufficient grinding and increasing the service life of the rollers. The baffle in a horizontal state can cover a large area of ​​the upper hopper opening, which can not only prevent the splashing of non-metallic minerals and reduce safety accidents, but also use the dust-proof film bonded to the surface of the baffle to adsorb the dust particles that escape, to protect the health of personnel and optimize the processing environment.

[0008] Furthermore, a grinding block is provided at the bottom of the first and second grinding rollers, a hydraulic push rod is fixedly connected to the side wall of the grinding block, and the end of the hydraulic push rod away from the grinding block is fixedly provided on the inner wall of the grinding box, a plurality of pressing teeth are fixedly connected to the sloped end of the grinding block, and a storage cavity is provided at the bottom of the grinding block, a hose is connected to the side wall of the storage cavity, the hose is connected to the external water tank, and a plurality of groups of steel brushes are fixedly provided at the bottom of the storage cavity, a plurality of through holes are provided at the bottom of the storage cavity, and a screen is fixedly connected to the bottom of the grinding box, and the screen is in contact with the bottom of the plurality of groups of steel brushes; the non-metallic minerals continue to fall to the middle of the two grinding blocks, and the hydraulic push rod is started to drive the two grinding blocks to continuously approach and move away from each other, and the non-metallic minerals are continuously pressed together and crushed by the pressing teeth. , thereby further reducing the particle size of non-metallic minerals, and can also meet the processing requirements of different non-metallic minerals for particle size by controlling the push-pull distance and push-pull times of the hydraulic push rod. In addition, during the pressing process, the grinding block will drive the steel brush at the bottom to brush the screen back and forth, thereby always ensuring the smoothness of the screen and effectively preventing the screen from being blocked. In addition, after the processing is completed, liquid or gas is continuously pumped into the hose through an external water tank or air pump, so that it is continuously sprayed on the steel brush, and the impurities attached to the steel brush and the screen are blown off by the gas vibration force, or the impurities on the steel brush and the screen are soaked and dissolved by the jet of high-temperature water, so that they are loosened and fall off by themselves, greatly reducing the manpower burden.

[0009] Furthermore, a motor is arranged outside the upper hopper, one end of the motor output shaft extends into the upper hopper and is fixedly connected with a baffle, and a dustproof film is bonded to the upper and lower surfaces of the baffle; Before the non-metallic minerals enter the grinding box, the motor controls the baffle to rotate to a vertical state so as not to affect the smoothness of the feeding. When the non-metallic minerals are ground, the motor controls the baffle to rotate to a horizontal state to cover the opening of the upper hopper, thereby preventing the materials from splashing out of the upper hopper during the grinding process and injuring people. The dust particles generated during the crushing can also be adhered to the sticky dust-proof film on the surface to prevent them from spreading to the external environment. The two sides of the baffle can also be flipped over for alternating use. The bonding method is convenient for personnel to replace regularly and effectively purifies the working environment.

[0010] Furthermore, a feed frame is arranged outside the grinding box, a plurality of legs are fixedly connected to the bottom of the feed frame, a driving motor is fixedly connected to one side of the leg, a roller is fixedly connected to the output end of the driving motor, the roller is rotatably connected between two adjacent legs, and a feed belt is rotatably arranged on the outer surface of the roller; the non-metallic minerals that have undergone multiple grindings are transported by the feed belt, without the need for personnel transfer, and the processing efficiency is higher, and the plurality of legs can fully support the feed frame, ensuring installation stability and operational firmness.

[0011] Furthermore, an outer wall of the feed frame is rotatably connected to an anti-overflow plate, and an outer wall of the feed frame is provided with a groove, an electric telescopic rod is arranged in the groove, the telescopic end of the electric telescopic rod is fixedly connected to the inner wall of the anti-overflow plate, and a dust-proof film is connected to the adjacent anti-overflow plate; when the volume of the non-metallic minerals on the conveyor belt is large or the transportation volume is large, the electric telescopic rod can be controlled to push the rotatably connected anti-overflow plate to rotate at an angle, and the single carrying capacity of the conveyor belt can be increased after the angle expansion, effectively preventing the non-metallic minerals from rolling down at the discharge port or during transportation. In addition, the non-metallic minerals rolling down from the discharge port will generate a large amount of smoke and dust, and will also be accompanied by a lot of smoke and dust during transportation, and the outward-expanded anti-overflow plate will stretch the dust-proof film at the top to deform, thereby increasing the coverage of the dust-proof film, and using the sticky dust-proof film to absorb the escaping dust to prevent the dust from further spreading to the outside.

[0012] Furthermore, a sponge layer is provided inside the anti-overflow plate, and a wet cloth layer is provided outside the sponge layer. The anti-overflow plate is made of hard material, and the dust-proof film has viscosity and ductility. A certain amount of moisture is stored inside the sponge layer, which is then transferred to the wet cloth layer, so that the wet cloth layer is always in a wet state, and the wet cloth layer is used to absorb dust escaping to both sides, and the dust-proof film is used to absorb dust escaping upward, thereby achieving the function of fully absorbing dust and preventing secondary pollution.

[0013] Furthermore, a material guide inclined plate is provided inside the material guide box, and a discharge port is opened on the side wall of the material guide box. The height of the discharge port is higher than the height of the conveyor belt. The material guide inclined plate can make the non-metallic minerals slide quickly to the discharge port position and then reach the surface of the conveyor belt to achieve the purpose of automated and efficient transportation.

[0014] Furthermore, a plurality of fixed teeth are fixedly provided on the surface of the second rolling roller, and a plurality of empty grooves are opened on the second rolling roller, and movable teeth are provided in the plurality of empty grooves, the top of the movable teeth is an arc structure, the top of the fixed teeth is a pointed cone structure, and the bottom of the movable teeth is fixedly connected to a bottom rod, and the bottom of the bottom rod is fixedly connected to a supporting rod, and the supporting rod is slidably connected to the side wall of the second rolling roller, the second rolling roller is a hollow structure, and the side wall of the second rolling roller is fixedly connected to an electric push rod, the movable end of the electric push rod is fixedly connected to a push frame, and the other end of the push frame is fixedly connected to a hinged rod, and the other end of the hinged rod is installed at the bottom of the supporting rod.

[0015] Compared with the prior art, the advantages of the present invention are: The non-metallic minerals are put into the upper hopper. At this time, the motor controls the baffle to rotate to a vertical state, thereby ensuring smooth feeding of the non-metallic minerals. The non-metallic minerals then fall to rollers one and two, and the motor is controlled to drive the baffle to rotate to a horizontal state. Then the motor is started to drive rollers one and two to rotate through the meshing of gear one and gear two, thereby fully crushing and pulverizing the non-metallic minerals. The raised roller teeth can effectively prevent the non-metallic minerals from directly colliding with roller one, thereby causing depressions and pits on the surface of roller one, and then causing gaps between the rollers, making it impossible to tightly press and crush the non-metallic minerals. While ensuring sufficient grinding, the service life of the rollers is increased. The baffle in a horizontal state can cover a large area of ​​the upper hopper opening, which can not only prevent the splashing of non-metallic minerals and reduce safety accidents, but also use the dust-proof film bonded to the surface of the baffle to adsorb the dust particles that escape, thereby protecting the health of personnel and optimizing the processing environment.

[0016] The non-metallic minerals continue to fall to the middle of the two grinding blocks, and the hydraulic push rod is started to drive the two grinding blocks to move closer and farther. The non-metallic minerals are continuously pressed and crushed by the pressing teeth, thereby further reducing the particle size of the non-metallic minerals. The pushing and pulling distance and the number of pushing and pulling times of the hydraulic push rod can also be controlled to meet the processing requirements of different non-metallic minerals for particle size. In addition, during the pressing process, the grinding block will drive the steel brush at the bottom to brush the screen back and forth, thereby always ensuring the smoothness of the screen and effectively preventing the screen from being blocked. In addition, after the processing is completed, liquid or gas is continuously pumped into the hose through an external water tank or air pump, so as to continuously spray it on the steel brush, and the impurities attached to the steel brush and the screen are blown off by the gas vibration force, or the impurities on the steel brush and the screen are soaked and dissolved by the jet of high-temperature water, so that they are loosened and fall off by themselves, greatly reducing the manpower burden.

[0017] The conveyor belt is used to transport non-metallic minerals that have been multi-milled, without the need for personnel transfer, which improves processing efficiency. Multiple legs can fully support the conveyor frame to ensure installation stability and operational stability.

[0018] When the non-metallic minerals on the conveyor belt are large in size or the transport volume is large, the electric telescopic rod can be controlled to push the rotating anti-overflow plate to rotate at an angle. After the angle is expanded, the single load capacity of the conveyor belt can be increased, effectively preventing the non-metallic minerals from rolling down at the discharge port or during transportation. In addition, the non-metallic minerals rolling down from the discharge port will produce a large amount of smoke and dust, and will also be accompanied by a lot of smoke and dust during transportation. The outward-expanding anti-overflow plate will stretch the dust-proof film on the top to deform, thereby increasing the coverage of the dust-proof film, and using the sticky dust-proof film to absorb the escaped dust to prevent the dust from further spreading to the outside.

[0019] (5) A certain amount of moisture is stored inside the sponge layer, which is then transferred to the wet cloth layer, so that the wet cloth layer is always in a moist state. The wet cloth layer is used to absorb the dust escaping to both sides. The dust is deeply absorbed into the pores of the sponge layer through the wet cloth layer. The dust escaping upward is then absorbed by the dust-proof film, thereby achieving the function of fully absorbing dust and preventing secondary pollution.

[0020] (6) The guide ramp enables the non-metallic minerals to slide quickly to the discharge port and then reach the surface of the conveyor belt to achieve the purpose of automated and efficient transportation. The motor controls the rotation angle of the baffle to adjust the feed port.

[0021] (7) When it is necessary to grind non-metallic minerals of different densities and batches, the electric push rod can be controlled to extend so that the push frame extends forward to push the hinged rod to a vertical state, thereby pushing out the movable teeth retracted in the empty slot, and grinding and crushing the material more finely, making the particle size of the non-metallic mineral smaller. When coarse grinding is performed, it is only necessary to control the electric push rod to retract, so as to pull the extended movable teeth back into the empty slot. By changing the number of grinding teeth, the extension length and the shape of the tooth body, the different grinding requirements of non-metallic minerals can be met, and it is very practical.

The baffle 14 in a vertical state will not contact the bottom roller 1 9. The non-metallic minerals then fall to the roller 1 9 and the roller 2 11. The motor 13 is controlled to drive the baffle 14 to rotate to a horizontal state, and then the motor 7 is started to drive the roller 1 9 and the roller 2 11 to rotate through the meshing of the gear 1 8 and the gear 2 10, so that the non-metallic minerals are fully crushed and pulverized. The raised roller teeth 12 can effectively prevent the non-metallic minerals from being crushed. The metal minerals directly collide with the roller 9, resulting in depressions and potholes on the surface of the roller 9, which in turn creates gaps between the rollers, making it impossible to tightly press and crush the non-metallic minerals, thereby ensuring sufficient grinding and increasing the service life of the rollers. The baffle 14 in a horizontal state can cover a large area of ​​the opening of the upper hopper 2, which can not only prevent the splashing of non-metallic minerals and reduce safety accidents, but also use the dust-proof film 27 bonded to the surface of the baffle 14 to absorb the escaping dust particles, thereby protecting the health of personnel and optimizing the processing environment.

In addition, during the pressing process, the grinding block 16 will drive the steel brush 20 at the bottom to brush the screen 29 back and forth, so as to always ensure the smoothness of the screen 29 and effectively prevent the screen 29 from being blocked. In addition, after the processing is completed, liquid or gas is continuously pumped into the hose 19 through an external water tank or air pump, so as to continuously spray it on the steel brush 20, and the impurities attached to the steel brush 20 and the screen 29 are blown off by the gas vibration force, or the impurities on the steel brush 20 and the screen 29 are soaked and dissolved by the jet of high-temperature water, so that they are loosened and fall off by themselves, which greatly reduces the manpower burden.

When the non-metallic mineral is ground, the motor 13 controls the baffle 14 to rotate to a horizontal state to block the opening position of the upper hopper 2, thereby preventing the material from splashing out of the upper hopper 2 during the grinding process and injuring personnel. The dust-proof film 27 bonded to the surface can also be used to adhere the dust particles generated during the crushing to prevent them from spreading to the external environment.
