A cracking tank

Abstract

The cracking tank provided by the present invention comprises a tank body and a stirring paddle. The tank body is a spherical tank body. At least three supports are connected to the lower part of the tank body. The supports are distributed in a ring shape with a material discharge port as the center, so that the tank body can be stably placed on a supporting surface through the supports. The stirring paddle comprises a stirring shaft and a paddle blade. The stirring shaft comprises a main shaft and a plurality of support shafts arranged on the main shaft at intervals. The support shaft extends in a direction perpendicular to the axis of the main shaft. The paddle blade is arranged at the end of the support shaft. The main shaft penetrates the tank body in a horizontal direction and passes through the spherical center of the tank body. When the stirring paddle rotates, the material is driven by the stirring paddle to move from bottom to top. The material located at the upper part of the tank body moves downward again under the action of gravity, and convectively collides with each other. At the same time, the support shaft also stirs the material. The paddle blade scrapes the material adhered to the inner wall of the tank body, thereby improving the stirring efficiency and achieving a better cracking effect. By arranging a sealing mechanism matching the main shaft on the tank body, the material can be prevented from leaking along the axis of the main shaft.

[0032] The up and down directions described in the present invention refer to Figure 1 The up-down direction in the present invention refers to the left-right direction. Figure 1 The left and right direction in .

[0033] like Figure 1-3As shown, the cracking tank provided by the present invention comprises: a tank body 10 and a stirring paddle 20, wherein the tank body 10 is a spherical tank body, and a feed port 11, a pressurizing port 152, a standby port 153, a safety valve port 154, a thermometer port 155, and a pressure gauge port 156 are provided at the upper portion of the tank body 10, a feed flange is provided at the feed port 11, the thermometer port 155 and the pressure gauge port 156 are provided on the feed flange at the feed port 11, the thermometer port 155 and the pressure gauge port 156 penetrate the feed flange in the horizontal direction, and the angle between the thermometer port 155 and the pressure gauge port 156 is 60°, a manhole 151 is provided at the middle portion of the tank body 10, a discharge port 12 is provided at the bottom of the tank body 10, and four supports 13 are connected to the lower portion of the tank body 10. The supports 13 are distributed in a ring shape with the discharge port 12 as the center; the stirring paddle 20 includes a stirring shaft 21 and a paddle 22, the stirring shaft 21 includes a main shaft 211 and a plurality of support shafts 212 arranged on the main shaft 211 at intervals, the main shaft 211 passes through the tank body 10 in the horizontal direction, the main shaft 211 passes through the center of the tank body 21, the main shaft 211 is a solid shaft, and a sealing mechanism 14 matching the main shaft 211 is provided on the tank body 10, the sealing mechanism 14 is used to prevent the material from leaking from the tank body 10 along the axial direction of the main shaft 211; the support shaft 212 extends in a direction perpendicular to the axis of the main shaft 211, adjacent support shafts 212 are perpendicular to each other, and the paddle 20 is arranged at the end of the support shaft 212, and the paddle 20 can scrape off the material adhered to the inner wall of the tank body 10.

[0034] like Figure 1-4 , Fig. 9 As shown, in this embodiment, in order to facilitate the connection of the support shaft 212 to the main shaft 211, a first groove 2111 for accommodating the support shaft 212 is provided on the main shaft 211, and each support shaft 212 includes two square steels 2121 and a plurality of bolts 2122, and the two square steels 2121 are symmetrically distributed on both sides of the main shaft 212 and staggered. The staggered means that the aligned portion of the two square steels is smaller than the length of the square steels. According to actual needs, the aligned length can be adjusted to adjust the distance between the blade 22 and the inner wall of the tank body 10, and the bolts 2122 are arranged at the same time. The bolt 2122 penetrates the two square steels 2121 and fixes them into a whole. When the above-mentioned alignment length needs to be adjusted, the two square steels 2121 are moved toward or away from each other in a direction perpendicular to the axial line of the main shaft 211, so that the threaded holes of the bolts 2122 are misaligned and then aligned. The two square steels 2121 are fixedly connected by the bolts 2122. In order to enhance the connection strength between the support shaft 212 and the main shaft 211, one of the bolts 2122 also penetrates the main shaft 211. When fixedly connected, the square steel 2121 is clamped in the first groove 2111.

[0035] like Figure 4-9As shown, in this embodiment, the blade 22 includes a fixing plate 221 and a scraper 222. The fixing plate 221 is welded to the square steel 2121 of the support shaft 212. The scraper 222 is slidably arranged on the fixing plate 221. Specifically, the scraper 222 is connected to the fixing plate 221 by a bolt 2222. When the bolt 2222 is tightened, the relative position between the scraper 222 and the fixing plate 221 can be locked. The hole on the scraper 222 for the bolt 2222 to pass through is a waist-shaped hole 2223. By adjusting the bolt 222 At a specific position in the waist-shaped hole 2223, the scraper 222 is moved toward or away from the inner wall of the tank body 10, thereby fine-tuning the distance between the scraper 222 and the inner wall of the tank body. In order to make the scraper match the curvature of the inner wall of the tank body 10, one side of the scraper 222 close to the inner wall of the tank body 10 is an arc-shaped side 2221, and the radius of the arc-shaped side 2221 is equal to the radius of the inner wall of the tank body 10. In order to facilitate scraping and further improve the mixing efficiency, the angle between the plane where the scraper 222 is located and the axis of the main shaft 211 is not The angle is very important. If the angle is too large, the scraper 222 will not be able to achieve the stirring effect. If the angle is too small, the torque required for the stirring paddle 20 to rotate will be greatly increased. From the perspective of stirring effect and energy loss, the angle is preferably 30°-60°. In this embodiment, the angle is 45°. In order to enhance the connection strength between the fixing plate 221 and the square steel 2121 of the support shaft 212, the blade 22 also includes a connecting plate 223. The plane where the connecting plate 223 is located is perpendicular to the extension direction of the support shaft 212. The plane is perpendicular to the plane where the fixed plate 221 is located, and the connecting plate 223 is U-shaped. The second groove 2231 inside the connecting plate 223 matches the outer wall shape of the square steel 2121 of the support shaft 212. The two ends of the connecting plate 223 are welded to the fixed plate 221, and the square steel 2121 of the support shaft 212 passes through the second groove 2231. There are three connecting plates 223 and they are arranged at intervals. When the stirring paddle 20 rotates, the connecting plate 223 can also play a stirring role on the material, thereby improving the stirring efficiency.

[0036] The cracking tank provided by the present invention has the following advantages compared with the prior art:

[0037] 1. By clamping the main shaft with two square steels 2121 and fixing it with bolts 2122, not only can the position of the square steel 2121 on the main shaft be adjusted according to needs, but also a stirring body with a spacing space can be formed at the part where the two square steels 2121 and the main shaft 211 do not overlap. When the stirring paddle 20 rotates, the stirring body can stir the material in the tank body 10, enhance the convection collision effect of the material, improve the stirring efficiency, and thus optimize the cracking effect. Since the support shaft 212 is located as a whole in the tank body 10, there is no possibility of material leakage, so square steel can be used to reduce weight and reduce the torque required to rotate the stirring paddle 20.

[0038] By setting the connecting plate 223 on the fixing plate 221, the connecting plate 223 forms Fig. 9 In the form of the middle ribs, when the stirring paddle 20 rotates, the connecting plate 223 can also stir the material in the tank body 10, enhance the convection collision effect of the material, improve the stirring efficiency, and further optimize the cracking effect.

They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
