Description

Technical Field

[0001] The invention relates to the technical field of pulverizing equipment, in particular to bentonite pulverizing processing equipment. Background Art

[0002] Bentonite is a hydrated clay mineral, mainly composed of montmorillonite. Its main characteristic is expansion. It can absorb a large amount of water in water and expand. Bentonite is widely used in drilling mud, wastewater treatment, building materials, cosmetics and food industries. Its good adsorption performance and plasticity make it very useful in many industrial processes. Bentonite mining is generally large and small bentonite gravel. The mined bentonite ore needs to be crushed. The crushed bentonite particles become smaller, so they have a higher specific surface area and can better absorb liquids and gases. The refined bentonite is easier to mix and disperse in other materials, which improves its efficiency and uniformity in industrial applications.

[0003] Bentonite processing requires crushing equipment. The existing bentonite crushing equipment still has some problems, such as:

[0004] 1. Traditional equipment lacks self-cleaning function, and often requires additional manpower costs to clean the inside of the equipment to maintain a long-lasting and good crushing effect;

[0005] 2. Traditional equipment often lacks a drying mechanism, and often requires the use of separate drying equipment to dry the bentonite before and after crushing in order to better crush the bentonite. This undoubtedly increases the process of repeated filling, collecting and transportation;

[0006] 3. Traditional bentonite crushing is often carried out in multiple equipment and steps, lacking the ability to quickly crush and discharge bentonite ore in specific scenarios, such as small quantities of bentonite (individual enterprises need to process small batches of bentonite during trial production or product development; small areas of soil improvement or plant cultivation require a small amount of refined bentonite, etc.). Therefore, the present invention proposes a bentonite crushing and processing equipment to solve the problems mentioned in the above background technology. Summary of the invention

The air outlet of the wind hood faces a plane spiral baffle in the drying box. The plane spiral baffle is made of all-copper material. The plane spiral baffle made of all-copper material not only conducts heat but also gathers heat. A rotating drive device connected to a turntable is provided in the drying box.

[0014] Preferably, the surface of the crushing part of the crushing head is evenly provided with hard protrusions, and the inner wall of the equipment casing is a rough grinding surface corresponding to the crushing part of the crushing head. The crushing part of the crushing head cooperates with the rough inner wall of the equipment casing to crush the bentonite ore, and a rotating drive device connected to the crushing head is installed inside the equipment casing.

[0015] Preferably, a compression spring located at the lower side of the movable strip is sleeved on the fixed shaft, and a movable wheel is installed at the inner center of the movable strip, and the movable wheel corresponds to the lower side of the conical spiral strip.

[0016] Preferably, the conical spiral strip is wound two times, and the upper and lower pitches of the conical spiral strip are both greater than the lengths of the front brush and the rear brush, and an opening corresponding to the movable strip is opened at the midpoint of the conical spiral strip, the width of the opening is greater than the width of the movable strip, and there is a certain distance between the movable wheel and the front brush to prevent the movable strip from hindering the rotational movement of the conical spiral strip.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention innovatively designs a hot air drying system. The drying box is located at the upper inlet of the equipment housing and is connected to the wind hood. The wind hood introduces hot air into the drying box through a hot air pipe. With the flat spiral baffle made of all copper, it has good thermal conductivity and heat preservation, and can efficiently heat the bentonite ore in the drying box. The rotation of the turntable and the design of the flat spiral baffle can ensure that the ore is heated and dried immediately during the discharging process. The dried bentonite ore becomes drier and looser, easier to crush, less adhered during the crushing process, and reduced equipment wear;

[0022] 2. The crushing head designed in the present invention is divided into a crushing part and a grinding part. The crushing part has hard protrusions, which cooperate with the rough surface of the inner wall of the shell for preliminary crushing. The grinding part is used for fine grinding, and the crushing work of bentonite is carried out in sections and steps. The grinding ring and the crushing head maintain opposite directions, which is conducive to the high-quality and high-efficiency rapid crushing of bentonite ore. The designed grinding ring can conveniently adjust the upper and lower positions, and can also achieve higher-precision grinding processing and adjustment, ensuring that the produced bentonite powder meets the expected particle size requirements;

[0023] 3. The conical spiral bar designed in the present invention ensures uniform material feeding, avoids the phenomenon of ore directly falling to the bottom, and improves the comprehensiveness of bentonite ore crushing. The movable wheel corresponding to the lower side of the conical spiral bar enables the movable bar to follow the conical spiral bar offset. The setting of the front brush and the rear brush can automatically clean the surface of the crushing head, ensuring the continuous good crushing effect of the crushing head, avoiding the accumulation of dust and ore fragments, reducing the need for manual maintenance, and improving the automation level and maintenance efficiency of the equipment.

[0024] In summary, this equipment integrates hot air drying, fine crushing and precise grinding seamlessly and seamlessly, and is adapted to the demand scenarios for the equipment to quickly and integratedly crush and discharge a small amount of bentonite, such as in construction or industrial maintenance, where a small amount of bentonite needs to be temporarily repaired or adjusted, reducing the dependence on multiple equipment. Its structure is cramped and compact, but the design is reasonable and easy to move, and its design can guarantee a certain degree of crushing requirements for bentonite.

[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.

[0036] Furthermore, the inclined unloading plate 14 facilitates the unloading of bentonite ore and enters the center position of the flat spiral baffle 13 of the turntable 16 through the unloading port 15, and hot air is introduced to dry the drying box 2. The flat spiral baffle 13 made of all copper is not only heat-conducting and heat-collecting, but also has a large contact area. When the rotating drive device in the drying box 2 drives the connected turntable 16 and the flat spiral baffle 13 to rotate, the bentonite ore passing through the inside can be effectively dried. Due to the shape of the flat spiral baffle 13, After rotating for several circles, the ore finally goes out of the plane spiral baffle 13 and enters the drying box 2. Since the drying box 2 is also arranged obliquely, the dried bentonite ore passes through the lower outlet of the drying box 2 to the interior of the lower device. The structural setting of the drying box 2 is not only convenient for hot air output, but also convenient for the discharge of steam generated after heating. The all-copper spiral baffle has a wide contact area and can effectively accumulate and guide the hot air heat source, thereby providing good and lasting drying conditions for the bentonite ore passing through the plane spiral baffle 13.

[0037] Furthermore, a crushing head 11 is rotatably connected inside the equipment housing 1. The crushing head 11 is divided into an upper and lower part. The upper part of the crushing head 11 is a crushing part. The surface of the crushing part of the crushing head 11 is evenly provided with hard protrusions, and the inner wall of the equipment housing 1 is a rough grinding surface corresponding to the crushing part of the crushing head 11. The crushing part of the crushing head 11 cooperates with the rough inner wall of the equipment housing 1 to crush the bentonite ore. A rotating driving device connected to the crushing head 11 is installed inside the equipment housing 1. The connected crushing head 11 is driven to rotate by the rotating driving device inside the equipment housing 1 to crush the bentonite ore. Conical spiral strips 12 are fixed on the periphery of the crushing part of the crushing head 11. The conical spiral strips 12 provide a material discharge obstacle to avoid the crushed bentonite from being discharged directly to the bottom layer along the surface of the crushing head 11, but to make it discharge along the conical spiral strips 12, thereby ensuring the crushing effect of the bentonite ore.

[0038] Furthermore, a movable bar 17 is provided on one side of the device housing 1, and a fixed shaft 9 corresponding to the movable bar 17 is fixed on the outer side of the device housing 1, the movable bar 17 slides up and down on the fixed shaft 9, and a front brush 23 and a rear brush 24 are respectively provided on the upper and lower sides of the inner side of the movable bar 17, and the upper and lower movable ranges of the movable bar 17 correspond to the crushing part of the crushing head 11, and an extrusion spring 10 located on the lower side of the movable bar 17 is sleeved on the fixed shaft 9, and a movable wheel 18 is installed at the inner center of the movable bar 17, and the movable wheel 18 corresponds to the lower side surface of the conical spiral bar 12, the number of turns of the conical spiral bar 12 is two, and the upper and lower pitches of the conical spiral bar 12 are greater than the lengths of the front brush 23 and the rear brush 24, and an opening 22 corresponding to the movable bar 17 is opened at the midpoint of the conical spiral bar 12, and the width of the opening 22 is greater than the width of the movable bar 17. There is a certain distance between the movable bar 18 and the front brush 23 to prevent the movable bar 17 from hindering the rotation of the conical spiral bar 12. During the rotation of the above-mentioned crushing head 11, the outer conical spiral bar 12 rotates with it and continuously squeezes the movable bar 17 through the corresponding movable wheel 18. After the conical spiral bar 12 rotates one circle, the movable wheel 18 loses its restriction and returns to its initial state under the elastic force of the squeezing spring 10 on the fixed shaft 9. The upper end of the movable bar 17 and the front brush 23 pass through the conical spiral bar 12 through the corresponding opening 22, and the same goes back and forth. When the conical spiral bar 12 continues to rotate with the crushing head 11, the front brush 23 and the rear brush 24 on the lower side of the movable bar 17 deviate downward accordingly to clean the crushing head 11 part passing through the path to prevent the bentonite powder and gravel from adhering.

[0039] Furthermore, the lower half of the crushing head 11 is a grinding part, and an outlet is provided at the lower part of one side of the equipment housing 1, and a grinding ring 19 corresponding to the grinding part of the crushing head 11 is provided at the outlet.

A screw 21 threadedly connected to the lower sliding shaft 25 is rotated on the adjusting frame 20, and a scale is arranged on one side of the sliding shaft 25 for observing the adjustment spacing of the grinding ring 19. By rotating the screw 21, the upper and lower positions of the grinding ring 19 connected to the sliding shaft 25 in the pulley 4 can be adjusted, and then the spacing between the grinding ring 19 and the grinding part of the crushing head 11 can be adjusted to control the degree of grinding and refining;

[0041] Furthermore, another pulley 4 is fixed to the lower side of the center of the turntable 16, and the other pulley 4 is located at the lower side of the drying box 2. The other pulley 4 and the pulley 4 on the equipment casing 1 are covered with the same transmission belt 5, and the drying box 2 and the equipment casing 1 are both equipped with left and right guide wheels 7 corresponding to the transmission belt 5.
