Description

Technical Field

[0001] This utility model relates to the technical field of diatomite processing equipment, and in particular to a low-grade diatomite crushing mechanism and its activation treatment equipment. Background Technology

[0002] Diatomaceous earth is a natural porous siliceous mineral material formed from the long-term deposition of ancient diatom remains. It has the characteristics of high porosity, large specific surface area and relatively stable chemical properties, and is therefore widely used in fields such as filtration aid, adsorption, heat preservation, catalyst carrier, filler and environmental protection.

[0003] In the prior art, the activation process of low-grade diatomaceous earth usually requires grinding. For example, Chinese invention patent application CN118458784A proposes a purification and activation method for low-grade clayey diatomaceous earth. In this method, the raw diatomaceous earth is sieved through a 200-mesh screen, and the sieve material is retained. Then, the sieve material is calcined, and the calcined diatomaceous earth is put into a ball mill for grinding to obtain pre-activated diatomaceous earth.

[0004] However, directly using a ball mill for grinding makes it difficult to control the degree of grinding, which can easily lead to some diatomaceous earth being over-crushed, resulting in poor grinding and processing effects. Utility Model Content

The transmission module is connected to the perforated plate and the discharge channel. The transmission module is connected to the main shaft and is used to transport diatomaceous earth.

[0006] Furthermore, the grinding module includes: a crushing component and a grinding component; The crushing component is located inside the main body of the outer shell and is connected to the main shaft for preliminary crushing of diatomaceous earth. The grinding assembly is located inside the main body of the housing and is connected to the main shaft. The grinding assembly is situated between the crushing assembly and the porous plate and is used to grind diatomaceous earth.

[0007] Furthermore, the crushing assembly includes: an annular liner and a conical crushing roller; The annular liner is fixedly installed on the inner wall of the outer shell body. The main shaft passes through the inner cavity of the annular liner, and the top port of the annular liner is connected to the feed port. The conical crushing roller is fixedly sleeved on the main shaft and located in the inner cavity of the annular liner. The outer diameter of the bottom end of the conical crushing roller is larger than the outer diameter of the top end of the conical crushing roller. The slit width between the outer circumferential surface of the conical crushing roller and the inner surface of the annular liner is greater than zero. The central axis of the conical crushing roller intersects with the central axis of the main shaft. It is used for extrusion crushing of diatomaceous earth.

[0008] Furthermore, the grinding assembly includes: a grinding ring, a transmission support, and several grinding rollers; The grinding ring is fixedly mounted on the inner wall of the outer casing. The transmission bracket is fixedly sleeved on the main shaft, and the transmission bracket is located between the crushing component and the perforated plate; Several grinding rollers are rotatably mounted on several connecting ends of the transmission bracket. The outer circumferential surfaces of the grinding rollers abut against the inner surface of the grinding ring, and the rotating shaft of any grinding roller is parallel to the central axis of the main shaft.

[0009] Furthermore, the grinding assembly also includes: several scrapers, which are fixedly mounted on the transmission bracket, with the tail end of any scraper abutting against the perforated plate to scrape up the diatomaceous earth accumulated in the inner cavity of the grinding ring.

[0010] Furthermore, the transmission module includes: a turntable and a guide plate; The turntable is fixedly sleeved on the main shaft. The turntable is located in the inner cavity of the outer shell body. The radial cross-sectional shape of the turntable matches that of the inner cavity of the outer shell body.

[0012] A low-grade diatomite crushing mechanism according to an embodiment of the present invention has the following beneficial effects: 1.

The purpose is to use the transmission bracket to drive multiple grinding rollers to rotate synchronously during the rotation of the main shaft, thus submerging the diatomaceous earth. In this process, the transmission bracket pushes the larger volume of diatomaceous earth to roll, causing the perforated plate to vibrate and promoting the smooth passage of diatomaceous earth with the required particle size through the sieve holes of the perforated plate, thereby improving the screening efficiency of the perforated plate. Secondly, the centrifugal force generated during the rotation of the transmission bracket drives the diatomaceous earth to converge towards the outer edge of the perforated plate, thereby improving the grinding efficiency of the grinding components.

Detailed Implementation

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0018] The foregoing and other technical contents, features, and effects of this utility model will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present utility model. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0019] First, combine Figures 1-5 This invention describes a low-grade diatomaceous earth crushing mechanism according to an embodiment of the present invention, which is used for powder processing of diatomaceous earth and has a wide range of applications.

[0020] Specifically, such as Figure 1 , 2 As shown, a low-grade diatomaceous earth crushing mechanism according to an embodiment of this utility model includes: a shell body 1, a discharge channel 11, a main shaft 2, a grinding module 3, a perforated plate 4, and a transmission module 5; the shell body 1 has an internal receiving chamber, and a feed inlet 12 is provided on the shell body 1; the discharge channel 11 is provided on the shell body 1 for conveying diatomaceous earth; the main shaft 2 is provided inside the shell body 1, the main shaft 2 is arranged along the axial direction of the shell body 1, and both ends of the main shaft 2 are rotatably connected to the shell body 1; the main shaft 2 is connected to an external driving device (see figure). (Not shown) is connected; the grinding module 3 is set inside the outer shell 1 and is connected to the main shaft 2 for grinding diatomaceous earth; the perforated plate 4 is fixedly set inside the outer shell 1 and matches the radial cross-sectional shape of the inner cavity of the outer shell 1. The perforated plate 4 is located between the grinding module 3 and the discharge channel 11 and is used to screen diatomaceous earth; the transmission module 5 is set inside the outer shell 1 and is connected to the perforated plate 4 and the discharge channel 11. The transmission module 5 is connected to the main shaft 2 and is used to transmit diatomaceous earth.

[0021] When the equipment is running, diatomaceous earth enters the receiving chamber of the outer shell 1 through the feed inlet 12. At the same time, the drive device controls the main shaft 2 to rotate, thereby driving the grinding and processing device and the transmission module 5 to run. The grinding and processing module 3 is used to grind the diatomaceous earth. During the grinding and processing of diatomaceous earth, the diatomaceous earth particles that meet the specifications are processed and fall into the transmission module 5 through the sieve holes of the perforated plate 4. The transmission module 5 then transports the diatomaceous earth particles to the discharge channel 11, and finally discharges them through the discharge channel 11. In this embodiment, by setting the perforated plate 4 between the grinding and processing module 3 and the transmission module 5, the diatomaceous earth is screened by the perforated plate 4 while the grinding and processing module 3 is grinding the diatomaceous earth. This allows the diatomaceous earth particles that meet the size requirements to be transported to the discharge channel 11 by the transmission module 5 in a timely manner, preventing the diatomaceous earth from being over-crushed, thus solving the defects existing in the prior art.

[0022] Furthermore, such as Figure 1 , 2 As shown, the grinding module 3 includes: a crushing component 31 and a grinding component 32; the crushing component 31 is disposed inside the outer shell 1 and is connected to the main shaft 2, and is used for preliminary crushing of diatomaceous earth; the grinding component 32 is disposed inside the outer shell 1 and is connected to the main shaft 2, and is located between the crushing component 31 and the porous plate 4, and is used for grinding of diatomaceous earth.

[0023] Furthermore, such as Figures 1-3 As shown, the crushing assembly 31 includes: an annular liner 311 and a conical crushing roller 312; the annular liner 311 is fixedly mounted on the inner wall of the outer shell 1, the main shaft 2 passes through the inner cavity of the annular liner 311, and the top port of the annular liner 311 is connected to the feed inlet 12; the conical crushing roller 312 is fixedly sleeved on the main shaft 2, the conical crushing roller 312 is located in the inner cavity of the annular liner 311, the outer diameter of the bottom end of the conical crushing roller 312 is larger than the outer diameter of the top end of the conical crushing roller 312, the slit width between the outer circumferential surface of the conical crushing roller 312 and the inner surface of the annular liner 311 is greater than zero, and the central axis of the conical crushing roller 312 intersects with the central axis of the main shaft 2, for extruding and crushing diatomaceous earth.

[0024] During the operation of the crushing assembly 31, the conical crushing roller 312 rotates under the drive of the main shaft 2. Since the central axis of the main shaft 2 intersects with the central axis of the conical crushing roller 312, the width of the slit between the outer edge of the bottom end of the main shaft 2 and the annular liner 311 changes periodically and dynamically during the rotation. As a result, the diatomaceous earth is crushed by the conical crushing roller 312 as it passes through the inner cavity of the annular liner 311. After being crushed, the diatomaceous earth smoothly passes through the slit between the conical crushing roller 312 and the annular liner 311 and falls onto the perforated plate 4.

[0025] Furthermore, such as Figure 1 , 2 As shown in Figure 4, the grinding assembly 32 includes: a grinding ring 321, a transmission bracket 322, and several grinding rollers 323; the grinding ring 321 is fixedly mounted on the inner wall of the outer shell 1; the transmission bracket 322 is fixedly mounted on the main shaft 2, and the transmission bracket 322 is located between the crushing assembly 31 and the perforated plate 4; several grinding rollers 323 are respectively rotatably mounted on several connecting ends of the transmission bracket 322, and the outer circumferential surfaces of several grinding rollers 323 abut against the inner surface of the grinding ring 321, and the rotation axis of any grinding roller 323 is parallel to the central axis of the main shaft 2, for grinding diatomaceous earth.

[0026] During the operation of the grinding assembly 32, the main shaft 2 drives the transmission support 322 to rotate, causing the transmission support 322 to drive multiple grinding rollers 323 to rotate around the main shaft 2. During this process, the grinding rollers 323 cooperate with the grinding ring 321 to further grind the diatomaceous earth falling on the porous plate 4, so that its particle size meets the requirements and falls smoothly through the sieve holes of the porous plate 4. Preferably, in this embodiment, during the rotation of the transmission support 322 driven by the main shaft 2, the transmission support 322 pushes the larger volume of diatomaceous earth to roll along, so as to cause the porous plate 4 to vibrate, promote the smooth passage of diatomaceous earth with the required particle size through the sieve holes of the porous plate 4, and improve the screening efficiency of the porous plate 4. At the same time, the centrifugal force generated during the rotation of the transmission support 322 drives the diatomaceous earth to gather towards the outer edge of the porous plate 4, so as to improve the grinding efficiency of the grinding assembly 32.

[0027] Furthermore, such as Figure 1 , 2 As shown in Figure 4, the grinding assembly 32 also includes: a plurality of scrapers 324, which are fixedly mounted on the transmission bracket 322. The tail end of any scraper 324 abuts against the perforated plate 4 and is used to scrape up the diatomaceous earth accumulated in the inner cavity of the grinding ring 321.

[0028] In this embodiment, during the rotation of the transmission bracket 322, multiple scrapers 324 are driven to rotate around the main shaft 2. The scrapers 324 scoop up diatomaceous earth that is small in volume and insufficient to pass through the sieve holes and place it at the grinding position between the grinding roller 323 and the grinding ring 321, so as to further improve the grinding efficiency of the grinding assembly 32.

[0029] Furthermore, such as Figure 1 , 2 As shown in Figure 5, the transmission module 5 includes: a turntable 51 and a guide plate 52; the turntable 51 is fixedly sleeved on the main shaft 2, the turntable 51 is located in the inner cavity of the outer shell body 1, the radial cross-sectional shape of the turntable 51 matches the inner cavity of the outer shell body 1, the turntable 51 is located directly below the perforated plate 4, and the circumferential outer edge of the turntable 51 is connected to the input end of the discharge channel 11; the guide plate 52 is fixedly installed at the input end of the discharge channel 11, the head end of the guide plate 52 is connected to the input end of the discharge channel 11, and the guide plate 52 abuts against the upper surface of the turntable 51.

[0030] During the operation of the transmission module 5, the spindle 2 drives the turntable 51 to rotate, so as to use the centrifugal force generated when the turntable 51 rotates to drive the diatomaceous earth falling on the turntable 51 through the perforated plate 4 to gather towards the outer edge of the turntable 51; then, under the guidance of the guide plate 52, the diatomaceous earth near the outer edge of the turntable 51 is guided into the discharge channel 11 and discharged through the discharge channel 11.

[0031] Another embodiment of this utility model proposes a low-grade diatomite activation treatment device, which includes the aforementioned low-grade diatomite crushing mechanism.
