Description

Technical Field

[0001] The invention belongs to the technical field of stirring devices, and in particular relates to a diatom mud stirring device. Background Art

[0002] Using an electron microscope to observe diatom mud, we can see that diatom mineral is a porous material with a pore size of micrometers. The surface of its particles has countless tiny holes, which are regularly and neatly arranged in circles and needles. The number of micropores per unit area is thousands of times more than that of charcoal. This molecular sieve structure gives it extremely strong physical adsorption and ion exchange properties. Therefore, in the process of stirring diatom mud with a stirring device, due to the high viscosity of diatom mud, the conventional stirring method causes the diatom mud to produce laminar flow, which results in uneven distribution of the diatom mud in the inner and outer layers. Therefore, it takes a long time to complete the stirring operation after the diatom mud is evenly distributed, so the above problems need to be solved. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described 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; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Depend on Figure 1-8 given;

[0031] Reference Figure 1-3The present invention relates to a diatom mud stirring device, comprising a tank body 1, wherein a mounting plate 2 and a mounting frame 3 are rotatably arranged inside the tank body 1, and a central stirring member 4 is arranged at the center of the mounting plate 2 and the center of the mounting frame 3. In order to solve the problem that in the process of stirring the diatom mud, the diatom mud has a large fluid viscosity after stirring, and the diatom mud is stirred in a conventional manner, so that the diatom mud produces a laminar flow phenomenon, resulting in uneven distribution of the diatom mud in the inner and outer layers, and it takes a long time to complete the stirring, a scraper guide member 5, an edge stirring member 6, a horizontal circulation member 7 and a vertical impact member are respectively arranged at the edge of the mounting plate 2. 8, wherein the top of the edge stirring member 6, the top of the horizontal circulation member 7, the top of the vertical counter-impact member 8 and the top of the central stirring member 4 are all fixedly provided with sprockets 9, and the multiple sprockets 9 are connected by a chain 10; wherein a driving mechanism 11 is provided on the tank body 1; in the working state, the driving mechanism 11 drives the mounting plate 2 and the central stirring member 4 to rotate, and the central stirring member 4 drives the horizontal circulation member 7 and the vertical counter-impact member 8 to move, so that the diatom mud circulates between the center of the tank body 1 and the inner edge of the tank body 1, and the circulation flow trajectory of the diatom mud is annular; and the diatom mud at the upper and lower parts of the tank body 1 is stirred after the counter-impact;

[0032] With such a design, when in use, diatom mud and water are fed into the tank body 1 through the feed port on the side of the tank body 1, and then the mounting plate 2 and the central stirring member 4 are driven simultaneously by the driving mechanism 11; wherein the mounting plate 2 drives the scraper guide member 5, the edge stirring member 6, the horizontal circulation member 7 and the vertical counter-attacking member 8 thereon to rotate in a circle at a relatively low speed, and the central stirring member 4 rotates at a relatively high speed at the center of the tank body 1 to stir the diatom mud; during this period, the diatom mud on the inner wall of the tank body 1 is scraped off by the scraper guide member 5, the diatom mud at the edge of the tank body 1 is stirred by the edge stirring member 6, and the diatom mud at the center and edge of the tank body 1 is circulated in the horizontal direction by the horizontal circulation member 7, so that the diatom mud is more evenly distributed during the stirring process, and the vertical counter-attacking member 8 can make the diatom mud impact after flowing in the vertical direction, further accelerating the fluidity of the diatom mud to improve the stirring efficiency.

[0033] Reference Figure 8In order to make the mounting plate 2 rotate at a low speed while the other components rotate at a higher speed, the driving mechanism 11 includes a driving motor 1101 fixedly arranged on the tank body 1, a driving shaft 1102 is fixedly arranged on the output shaft of the driving motor 1101, and a first driving gear 1103 and a second driving gear 1104 are fixedly arranged on the driving shaft 1102; wherein the first driving gear 1103 is meshed with a first driven gear 1105 fixedly arranged on the mounting plate 2, the first driven gear 1105 is rotationally matched with the central shaft 401 on the central stirring member 4, and the second driving gear 1104 is meshed with a second driven gear 1106 on the central stirring member 4, wherein the rotation speed of the second driven gear 1106 is greater than the rotation speed of the first driven gear 1105;

[0034] In this design, the driving motor 1101 drives the driving shaft 1102 to rotate, and the first driving gear 1103 on the driving shaft 1102 drives the first driven gear 1105 on the mounting plate 2 to rotate by meshing. The radius of the first driving gear 1103 is smaller than the radius of the first driven gear 1105, so that the first driven gear 1105 drives the mounting plate 2 to rotate at a lower speed; at the same time, the second driving gear 1104 on the driving shaft 1102 drives the second driven gear 1106 on the central stirring member 4 to rotate by meshing, so that the central stirring member 4 rotates at a higher speed; then the central stirring member 4 drives the edge stirring member 6, the horizontal circulation member 7 and the vertical impact member 8 to rotate at a higher speed through the cooperation of the sprocket 9 and the chain 10.

[0035] Reference Figure 4 The central stirring member 4 includes a central rotating shaft 401 rotatably arranged between the mounting plate 2 and the mounting frame 3, and a central stirring rod 402 is evenly fixedly arranged on the central rotating shaft 401; wherein the second driven gear 1106 and the sprocket 9 on the central stirring member 4 are both fixedly arranged on the central rotating shaft 401; such a design makes it easy to drive the central stirring rod 402 to rotate through the central rotating shaft 401, and stir the diatom mud in the middle of the tank body 1 through the central stirring rod 402.

[0036] Reference Figure 4 The edge stirring member 6 includes an edge shaft 601 rotatably arranged between the mounting plate 2 and the mounting frame 3, and edge stirring rods 602 are evenly fixedly arranged on the edge shaft 601; wherein the sprocket 9 on the edge stirring member 6 is fixedly arranged on the edge shaft 601; such a design makes it easy to drive the edge stirring rod 602 to rotate through the edge shaft 601, and stir the diatom mud at the inner edge of the tank body 1 through the edge stirring rod 602.

[0037] Reference Figure 4-5The horizontal circulation member 7 includes a circulation shaft 701 rotatably arranged between the mounting plate 2 and the mounting frame 3, and a circulation rod 702 is evenly fixedly arranged on the circulation shaft 701; two material blocking frames 703 are also fixedly arranged between the mounting plate 2 and the mounting frame 3, and the two material blocking frames 703 are distributed on both sides of the circulation shaft 701, and the two material blocking frames 703, the circulation shaft 701 and the central axis of the tank body 1 are located on the same plane;

[0038] A plurality of U-shaped portions 704 are formed on the material blocking frame 703, and the U-shaped portions 704 are used in conjunction with the circulation rod 702, and the openings of the U-shaped portions 704 face the direction of the circulation shaft 701;

[0039] With this design, during specific installation, the open end of the U-shaped portion 704 can be as close to the circulation shaft 701 as possible, so that when the circulation shaft 701 drives the circulation rod 702 to rotate, when the circulation rod 702 passes through the U-shaped portion 704 on the material blocking frame 703, the diatom mud driven by the circulation rod 702 will be blocked by the material blocking frame 703, so that the diatom mud will collide with the material blocking frame 703 and then flow to both sides of the material blocking frame 703, thereby further accelerating the mixing process of the diatom mud;

[0040] The material blocking rack 703 can be arranged as shown in the accompanying drawings during installation. Preferably, the two material blocking racks 703 can be rotated a certain angle along their respective center lines so that the two material blocking racks 703 are in a parallel state. At this time, the openings of the U-shaped portions 704 of the two material blocking racks 703 are relatively offset. In this way, after the diatom mud is blocked by the material blocking rack 703, the diatom mud will roughly move along the surface of the material blocking rack 703, and the same movement will be carried out on the other side. Between the two corresponding horizontal material blocking racks 703, a roughly circular movement trajectory of the diatom mud is formed, thereby accelerating the mixing degree of the diatom mud inside and outside to improve the stirring efficiency.

[0041] Reference Figure 6 The vertical impact piece 8 includes a cylinder 801 fixedly arranged between the mounting plate 2 and the mounting frame 3, a rotating rod 802 is arranged inside the cylinder 801, and the rotating rod 802 is rotatably arranged between the mounting plate 2 and the mounting frame 3. Both ends of the rotating rod 802 are fixedly provided with spiral blades 803, and the spiral directions of the two spiral blades 803 are opposite. A breaking rod 804 is fixedly arranged in the middle of the rotating rod 802, and an annular opening 805 is formed in the middle of the cylinder 801 near the breaking rod 804; wherein the sprocket 9 on the vertical impact piece 8 is fixedly arranged on the rotating rod 802;

[0042] With such a design, when the rotating rod 802 rotates, the spiral blades 803 at both ends thereof also rotate therewith, so that the diatom mud at the top and the bottom of the tank body 1 both flow toward the middle of the tank body 1. After the diatom mud flows to the middle, the breaking rod 804 on the rotating rod 802 will break up and mix the diatom mud in the middle, thereby further increasing the mixing rate of the diatom mud.

[0043] Reference Figure 3 as well as Figure 7 The scraper guide 5 includes two electric push rods 501, an annular plate 502 and a scraper 503; wherein the two electric push rods 501 are fixedly arranged on the tank body 1, the annular plate 502 is fixedly arranged on the output ends of the two electric push rods 501, and the scraper 503 is slidably arranged on the mounting plate 2 and slidably cooperates with the annular plate 502;

[0044] The scraper 503 includes a square slide bar 504 slidably arranged in a square hole on the mounting plate 2, a sliding block 505 is fixedly arranged on the top of the square slide bar 504, a slide groove 506 on the sliding block 505 is slidably matched with the annular plate 502, a plurality of scraper plates 507 are fixedly arranged in the middle of the square slide bar 504, and a telescopic rod 508 and a flexible sleeve 509 located on the outside of the telescopic rod 508 are connected between the bottom end of the square slide bar 504 and the mounting frame 3;

[0045] With such a design, during use, when the square slide bar 504 rotates with the mounting plate 2, the scraper plate 507 thereon will scrape the diatom mud attached to the inner wall of the tank body 1, and at the same time, the annular plate 502 is driven up and down by the electric push rod 501, and the annular plate 502 drives the sliding block 505 to move through the slide groove 506, and the sliding block 505 drives the scraper plate 507 to move through the square slide bar 504, thereby expanding the scraping range of the scraper plate 507. Since the area of ​​the scraper plate 507 is small, the resistance it encounters during rotation is also small, which is convenient for driving.

[0046] One end of the scraper plate 507 is in contact with the inner wall of the tank body 1, and the other end of the scraper plate 507 faces the inner side of the tank body 1; a guide groove 510 is formed on the scraper plate 507, and the inner bottom wall of the guide groove 510 is inclined;

[0047] With this design, the scraped diatom mud can be guided to the inner side of the tank body 1 through the guide groove 510, so as to be stirred by the edge stirring member 6 or the center stirring member 4, so that the diatom mud can be fully mixed together. This can avoid the situation where the diatom mud on the inner wall of the tank body 1 takes a long time to be stirred due to the limited stirring range.
