Description

Technical Field

[0001] The invention relates to the field of grinding technology, in particular to a grinding device with an adjustment function for pesticide production. Background Art

[0002] At present, pesticides refer to chemical agents used in agriculture to prevent and control pests and diseases and regulate plant growth. Pesticide raw materials mainly include chemical synthetic substances, natural plant extracts, microbial source substances and mineral raw materials (such as limestone). In the process of pesticide production, in order to make pesticide raw materials into pesticide preparations with uniform dispersion and good suspension, ball mills are generally used to grind mineral raw materials. Ball mills are a horizontally placed grinding equipment, which consists of a rotating drum and several balls. The working principle is as follows: The mineral raw materials are placed in the drum. Through the rotation of the drum, the balls and the mineral raw materials are lifted to a certain height and then fall down, which produces impact and friction and shear between the balls and the mineral raw materials, so that the mineral raw materials are gradually broken and ground into fine powder.

[0003] In the process of grinding mineral raw materials with existing ball mills, due to the different particle sizes of the mineral raw materials in the ball mill, the balls will inevitably hit the small-particle mineral raw materials when they are brought into the highest point of the drum and fall downward. When the balls hit the small-particle mineral raw materials, part of the kinetic energy of the balls will be absorbed by the small-particle mineral raw materials, which will reduce the impact force of the balls on the large-particle mineral raw materials, resulting in a decrease in the grinding efficiency of the large-particle mineral raw materials, while the potential energy and impact force of the balls cannot be effectively utilized, thus affecting the overall grinding efficiency.

During the process of grinding materials, not only can materials with small particle sizes and large particle sizes be processed separately, but also materials with small particle sizes can be refined, reducing the overall time required for grinding the materials, thereby improving the efficiency of grinding the materials.

Detailed Embodiments

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In order to solve the problem that in the process of grinding materials in the existing ball mill, the impact force of the ball on the large particle size is reduced due to the different particle sizes of the materials, the present invention collects the small particle size materials in advance, so that the ball mill grinds the large particle size materials first, and then releases the small particle size materials in time, avoiding the energy of the ball being wasted on the small particle size materials, thereby improving the overall grinding efficiency.

[0020] Example 1: A grinding device with an adjustment function for pesticide production, such as Figure 1-Figure 10 As shown, it includes: a base 10; a driving member 11, which is fixedly connected to one side of the base 10; a base frame 12, which is arranged on the other side of the base 10, the base frame 12 is rotatably connected to a swing frame 13, the swing frame 13 is rotatably connected to a first connecting shell 14, the first connecting shell 14 is fixedly connected to a rotating shell 15; a second connecting shell 16 is splined to the telescopic end of the driving member 11, the second connecting shell 16 is fixedly connected to a fixed shell 17; a rotating drum 18, which is fixedly connected to the rotating shell 15 and rotatably connected to the fixed shell 17, the fixed shell 17 is fixedly connected to a fixed frame 181 rotatably connected to the rotating shell 15, and fixed members 182 distributed at intervals are fixedly connected in the rotating drum 18, and the fixed members 182 distributed at intervals are all connected to the fixed frame 181. contact; a filter plate 183, which is arranged on the fixed frame 181; a first rotating shell 19, which is fixed to the rotating shell 15 and rotatably connected to the fixed shell 17, a guide plate 191 is fixed in the first rotating shell 19, and the first rotating shell 19 is provided with spaced material guide grooves 192; a shielding component, which is arranged on the fixed frame 181, is used to shield the upper side of the fixed frame 181, the filter plate 183 is located on one side of the vertical plane where the central axis of the rotating drum 18 is located, and is used to reduce the impact force of the material on the filter plate 183, the first rotating shell 19 is in contact with the fixed frame 181, the guide plate 191 is composed of an arc piece and a rectangular plate, and the arc piece in the guide plate 191 is used to increase the carrying capacity of the material.

[0021] In the above scheme, the drum 18 is provided with a cover plate, and a driving component for driving the drum 18 to rotate is provided on the swing frame 13. The rotating shell 15 and the fixed shell 17 are both connected by two semicircular shell bolts for easy disassembly. The driving component on the swing frame 13 is composed of a motor, a reducer, a coupling, a driving gear and a driven gear. The motor and the reducer are fixed to the swing frame 13, the power output shaft of the motor is connected to the reducer, the reducer is connected to the coupling, the coupling is connected to the driving gear key, and the drum 18 is connected to the driven gear key. The driving gear is connected to the driven gear by transmission, and the filter plate 183 is placed in the fixed frame 181 through two limit plates to facilitate the replacement of the filter plate 183. The fixed frame 181 and the drum 18 are used to collect small-size materials, so that large-size materials are ground first, and the impact force of the balls is fully utilized to improve the efficiency of grinding the materials. The driving member 11 is a hydraulic push rod, and the driving shaft of the driving member 11 is fixedly connected to a U-shaped frame, and the U-shaped frame is rotatably connected to a sliding ring splined with the second connecting shell 16, and the bottom frame 12 is rotatably connected to the swing frame 13; The existing ball mill will feed from one side of the ball mill during the grinding process, which will cause the material to accumulate on the feed side of the ball mill. During this process, when the material is ground by the ball mill, the material will gradually move to the other side of the ball mill. The above problem is that the balls in the ball mill far away from the feed side cannot play a role during the initial rotation of the ball mill, which will cause a waste of ball resources. To solve the above problem, before the ball mill is ground, the present invention raises the height of the left side of the rotating drum 18 (the left side of the rotating drum 18 is the feed side) through the driving member 11 to adjust the position of the rotating drum 18, so that the material in the rotating drum 18 can be transferred to the right side, so that the material can be evenly distributed in the rotating drum 18. After the material is evenly distributed, the height of the left side of the rotating drum 18 is lowered by the driving member 11 until it is aligned with the rotating drum 18. Figure 1 Just be consistent.

[0022] like Figure 6 and Figure 8 As shown, the material guide groove 192 is a parallelogram, and there is always an angle between the side of the material guide groove 192 located in the direction of the central axis of the rotating drum 18 and the fixed frame 181.

[0023] In the above scheme, if Figure 8 As shown, the front and rear side surfaces of the material guide trough 192 located on the lower side are parallel to the vertical plane where the central axis of the drum 18 is located, so that the front side surface of the material guide trough 192 located on the lower side can carry the material upward, and after the side surface rotates to the upper part of the drum 18, the part falls under the action of the material guide trough 192 (its effect is consistent with the effect of the baffle plate inside the existing ball mill).

[0024] like Fig. 9 and Fig.10As shown, the shielding assembly includes: an arc plate 20, which is slidably connected to the upper side of the fixed frame 181; first discharge ports 22 distributed at intervals, which are all arranged on the arc plate 20; second discharge ports 23 distributed at intervals, which are all arranged on the upper side of the fixed frame 181, and the number of the second discharge ports 23 is the same as that of the first discharge ports 22. The arc plate 20 is used to shield all the second discharge ports 23. The shielding assembly also includes: an airbag 21, which is fixedly connected to the upper side of the fixed frame 181 and is fixedly connected to the arc plate 20.

[0025] In the above scheme, the spaced first discharge ports 22 are located on the upper side of the middle of the drum 18, so that the material falls from the highest height when falling from the second discharge port 23 and the adjacent first discharge port 22, so that the material has impact force when falling.

[0026] Working principle: When the material needs to be ground, the staff first connects the external pressure control device to the airbag 21, then puts the ball into the first rotating shell 19 through the left side of the second connecting shell 16, and finally puts the material into the first rotating shell 19 through the left side of the second connecting shell 16. The material in the first rotating shell 19 falls onto the filter plate 183 through the adjacent material guide groove 192, and the small particle size material falls between the rotating drum 18 and the fixed frame 181 through the filter plate 183.

[0027] When the placement of the materials is completed, the staff seals the back sides of the second connecting shell 16 and the first connecting shell 14, and then starts the driving component on the swing frame 13, so that the driving component drives the rotating drum 18 to rotate (clockwise from right to left). During the rotation of the rotating drum 18, the first connecting shell 14 is driven to rotate along the swing frame 13 through the rotating shell 15. During the rotation of the rotating drum 18, all the fixing parts 182, the first rotating shell 19, and all the guide plates 191 are also driven to rotate along the fixed shell 17. The first rotating shell 19 rotates along the fixed frame 181 during the rotation.

[0028] During the process of grinding the material, the small-particle material in the first rotating shell 19 continuously moves to the upper side of the filter plate 183 through the adjacent material guide groove 192, and then continuously falls into the space between the rotating drum 18 and the fixed frame 181 through the filter plate 183, and then the rotating drum 18 drives all the fixing parts 182 to rotate, and the small-particle material between the rotating drum 18 and the fixed frame 181 is driven by the fixing parts 182, thereby realizing the pre-collection of the small-particle material and reducing the obstruction of the small-particle material to the ball, thereby improving the processing efficiency of the large-particle material.

[0029] During the grinding process of the material, the first rotating shell 19 drives all the guide plates 191 to rotate. During the rotation of the guide plates 191 and the first rotating shell 19 from the lower side to the rear, the guide plates 191 take away part of the material and the balls. The arc-shaped pieces in the guide plates 191 collect the material, thereby improving the material conveying capacity of the first rotating shell 19. After the guide plates 191 move to the upper side of the fixed frame 181, the guide plates 191 bring the carried material and the balls to the highest position in the first rotating shell 19 (that is, the upper middle side in the first rotating shell 19). Subsequently, the rectangular plate in the guide plate 191 swings with the first rotating shell 19, allowing the material and the balls to fall freely along the rectangular plate of the guide plate 191, so that the material and the balls impact the material on the lower side to achieve grinding of the material.

[0030] When the materials and balls fall downward, since the installation position of the filter plate 183 is not in the middle of the fixed frame 181, the probability of the materials and balls hitting the filter plate 183 is reduced, thereby extending the service life of the filter plate 183.

[0031] After the material is ground continuously for a period of time, the staff regularly reduces the pressure in the airbag 21 through the external pressure control device. After the pressure in the airbag 21 is reduced, the adjacent arc-shaped plates 20 are driven to rotate along the fixed frame 181, so that all the first discharge ports 22 are connected with the adjacent second discharge ports 23 respectively and correspond one to one. Then the staff stops operating the external pressure control device, and during the rotation of all the fixing parts 182, the small-particle material between the drum 18 and the fixed frame 181 is sent to the upper side of the fixed frame 181, and the small-particle material then falls from the first discharge port 22 and the second discharge port 23 on the upper side of the fixed frame 181 into the first rotating shell 19, so that the material is ground by the balls, and the material that can pass through the filter plate 183 also enters between the drum 18 and the fixed frame 181 through the filter plate 183. The rotation of the drum 18 and the first rotating shell 19 realizes the circulation transfer of the material, thereby improving the grinding efficiency of the material. After the above operation, the material is gradually ground into powder.

[0032] When the grinding of the material is completed and the material is ground into powder, the staff turns off the driving component on the swing frame 13, then releases the blockage on the back side of the second connecting shell 16 or the first connecting shell 14, and finally the staff takes out the powdered material in the drum 18 (the cover on the drum 18 can be opened to take out the powdered material).

[0033] Embodiment 2: Based on embodiment 1, Figure 8 and Figure 11-13As shown in the figure, it further includes a discharging assembly disposed on the fixed housing 17 for discharging the materials meeting the particle size in the rotating drum 18. The discharging assembly includes a gas guiding housing 30 fixedly connected to the fixed housing 17; a second rotating housing 31 rotatably and limitedly connected to the gas guiding housing 30. The gas guiding housing 30 is communicated with the second rotating housing 31. The second rotating housing 31 is fixedly connected to the rotating drum 18. The second rotating housing 31 is fixedly connected and communicated with intake pipes 32 distributed at intervals. The intake pipes 32 distributed at intervals are all fixedly connected to the rotating drum 18. The side of the rotating drum 18 away from the fixed housing 17 is fixedly connected and communicated with outlet pipes 33 distributed at intervals.

[0034] In the above solution, the powdery materials are preferentially discharged from the rotating drum 18 in the way of air separation, reducing the amount of powdery materials in the rotating drum 18.

[0035] As Figure 8 and Figure 11-Figure 14 As shown in the figure, the fixing member 182 is composed of a first C-shaped housing 1821, a second C-shaped housing 1822, a sliding frame 1823 and a sliding pin 1824. The first C-shaped housing 1821 is fixedly connected to the rotating drum 18. The first C-shaped housing 1821 is slidably connected to the second C-shaped housing 1822. The second C-shaped housing 1822 is slidably connected to the sliding frame 1823. A spring is fixedly connected between the second C-shaped housing 1822 and the sliding frame 1823. The second C-shaped housing 1822 is located between the first C-shaped housing 1821 and the sliding frame 1823. The second C-shaped housing 1822 is fixedly connected to the sliding pin 1824. The side of the sliding frame 1823 facing away from the first C-shaped housing 1821 is arranged in a corrugated shape for guiding the surrounding materials.

[0036] In the above solution, through the shortening of the distance between the sliding frame 1823 and the fixed frame 181, the preliminary crushing of the materials between the fixed frame 181 and the rotating drum 18 is realized, reducing the particle size of the materials. Under the action of the corrugated shape on one side of the sliding frame 1823, the sliding frame 1823 can effectively drive the materials to slide along the outside of the fixed frame 181, and through the extrusion force generated between the sliding frame 1823 and the fixed frame 181, the materials are repeatedly crushed, further reducing the particle size of the materials.

[0037] As Figure 11-Figure 14 As shown in the figure, it further includes a guiding assembly disposed on the fixed housing 17 for enabling all the second C-shaped housings 1822 to slide along the adjacent first C-shaped housings 1821 respectively. The guiding assembly includes a fixing plate 40 fixedly connected to the fixed housing 17. The fixing plate 40 is provided with a guiding groove 41. The guiding groove 41 is annular and wavy. The sliding pin 1824 slides along the guiding groove 41.

[0038] In the above scheme, when the sliding pin 1824 slides along the guide groove 41 to the side of the guide groove 41 close to the fixed frame 181, the spring adjacent to the sliding frame 1823 is compressed, and the sliding frame 1823 applies an extrusion force to the fixed frame 181. When the sliding pin 1824 slides along the guide groove 41 to the side of the guide groove 41 away from the fixed frame 181, the sliding frame 1823 does not contact the fixed frame 181.

[0039] Working principle: Before grinding the material, the staff connects the air supply port of the external air supply device to the air guide shell 30, and then connects the air exhaust port of the external exhaust device to all the air outlet pipes 33, thereby completing the preparation work before material grinding.

[0040] After completing the preparation work before material grinding, the driving component drives the drum 18 to rotate. During the rotation of the drum 18, the second rotating shell 31 is driven to rotate along the air guide shell 30. During this process, the external air supply device conveys gas into the air guide shell 30, so that the air guide shell 30 guides the gas into the second rotating shell 31, and then the second rotating shell 31 conveys the gas to between the drum 18 and the fixed frame 181 through all the air inlet pipes 32. During this process, the external exhaust device extracts the gas between the drum 18 and the fixed frame 181 through all the air outlet pipes 33, so that the gas in the drum 18 and the fixed frame 181 circulates, and carries some dust when the gas is discharged (a cyclone separator can be installed on the outside of the external exhaust device to separate the gas and dust). The gas and dust between the drum 18 and the fixed frame 181 are discharged through the above process to avoid excessive dust causing a decrease in grinding efficiency (because the powder will interfere with the effective contact between the balls and the material, and will reduce the grinding force between the two, thereby reducing the grinding efficiency of the material).

[0041] During the process of grinding the material, the rotating drum 18 drives all the first C-shaped shells 1821 and their attached parts to rotate. During this process, the second C-shaped shell 1822 and the adjacent sliding pins 1824 continuously drive the adjacent sliding frames 1823 to slide along the guiding groove 41, so as to enable the second C-shaped shell 1822 to reciprocate while rotating with the rotating drum 18. When the second C-shaped shell 1822 drives the adjacent sliding frame 1823 to slide through the spring, the distance between the sliding frame 1823 and the fixed frame 181 gradually increases or decreases. When the distance between the sliding frame 1823 and the fixed frame 181 is the largest, the sliding frame 1823 does not contact the fixed frame 181. When the distance between the sliding frame 1823 and the fixed frame 181 is the smallest, the sliding frame 1823 moves to contact the fixed frame 181. During this process, the sliding frame 1823 extrudes the material between it and the fixed frame 181, thereby realizing the preliminary crushing of the material and reducing the particle size of the material. Under the action of the corrugated shape on one side of the sliding frame 1823, when the sliding frame 1823 extrudes the surrounding material, it can effectively drive the material to slide along the outside of the fixed frame 181, and through the extrusion force generated between the sliding frame 1823 and the fixed frame 181, the material between the two is repeatedly crushed to further reduce the particle size of the material. By circulating the material in the rotating drum 18 as proposed in Embodiment 1 and cooperating with the exhaust mentioned above, the processing efficiency of the material in the rotating drum 18 is improved.

[0042] During the process of grinding the material, through the ventilation between the rotating drum 18 and the fixed frame 181 mentioned above, the powdered ore raw materials in the two are discharged, so as to realize the discharge of the powdered ore raw materials without reopening the first connecting shell 14 and the second connecting shell 16, simplifying the work process and shortening the processing time of the powdered ore raw materials.

[0043] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited by the above embodiments.
