Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a crushing device for a reaction vessel. Background Technology

[0002] The reactor is the main equipment for producing flocculant mixtures. During the production of flocculant mixtures, the flocculant (such as polyacrylamide) often clumps when mixed with water, easily clogging the customer's pipelines and affecting the customer's safe production.

[0003] When preparing flocculant mixtures using existing reactor stirring devices, the stirring action of the agitator alone can break up large clumps, but small clumps are difficult to break up and dissolve. Furthermore, the agitator itself has a weak crushing function. Even if large clumps can be broken up, the small clumps that form are still difficult to break up, which can easily cause abnormal situations such as pipeline blockage and adversely affect safe production.

[0004] The existing solution is to add blades to the stirring shaft so that the clumps collide with the blades during the mixing process and are thus broken up. However, this solution has a problem: because the water in the reactor becomes a high-speed rotating vortex under the agitation of the stirring paddle, the clumps will gradually move towards the reactor wall under the action of centrifugal force. In the reactor, it is difficult for the clumps on the reactor wall to return to the center and come into contact with the stirring paddle blades again, so the breaking effect is not good. Summary of the Invention

[0005] This invention provides a crushing device for a reaction vessel, which can solve the problem of poor crushing effect of clumps located on the vessel wall.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A crushing device for a reaction vessel includes a back plate, a speed-increasing plate, and a crushing blade; there are multiple back plates, the back of which is an arc surface that matches the arc shape inside the reaction vessel wall, and the back plates are connected by telescopic rods to form a closed loop. The whole is set inside the reaction vessel and supported on the vessel wall, with the back of the back plate in contact with the vessel wall.

[0008] The speed-increasing plate is mounted on and connected to the back plate; the speed-increasing plate is an arc-shaped plate, and there are multiple crushing blades, which are mounted on the convex arc surface of the arc-shaped plate.

[0009] The multiple cutting blades are arranged in a linear array on the convex surface of the arc-shaped plate.

[0010] The crushing blade is connected to the convex arc surface of the arc plate via a blade holder.

[0011] The blade holder is provided with a slot; the shredder is a No. 11 scalpel, the handle of which is inserted into the slot and connected to the blade holder by bolts; the blade holder is connected to the convex arc surface of the arc plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) The crushing blade of the crushing device provided by this utility model is located on the vessel wall, which can cut and crush the clumps that move towards the vessel wall under the action of centrifugal force, improve the crushing effect of the clumps, thereby improving the dissolution rate and effect of the flocculant clumps, and at the same time solve the problem of pipeline blockage caused by flocculant clumps.

[0014] 2) In this utility model, the speed-increasing plate is an arc-shaped plate. The convex arc surface of the arc-shaped plate causes the water flow to change from the original laminar flow state to a turbulent flow state when the water flow comes from the direction of the crushing blade. This intensifies the disturbance force when the agglomerate meets the linear array of crushing blades, making the agglomerate easier to cut. The fragments are carried away from the crushing blade by the water flow and will not remain on the blade, thus not affecting the continued function of the crushing blade.

[0015] 3) The shredder in this utility model is a No. 11 surgical knife, which is a standardized product, easy to obtain, and inexpensive; and the surgical knife and the knife holder are connected by bolts, which makes installation and disassembly convenient, facilitates replacement of the surgical knife, and makes maintenance convenient.

The speed-increasing plate 4 is an arc-shaped plate, and seven cutting blades 5 are arranged in a linear array (7 rows * 1 column) on the convex surface of the arc-shaped plate. The blades of the cutting blades 5 face the direction of water flow.

[0028] The scalpel 5 is a No. 11 surgical scalpel, and it is connected to the convex surface of the curved plate via the scalpel holder 7. The No. 11 surgical scalpel can be purchased from Huai'an Jiabo Medical Equipment Co., Ltd.

[0029] The scalpel holder 7 has a slot 71. The handle of the scalpel is inserted into the slot 71, and the end of the handle contacts the bottom of the slot 71. The scalpel and the scalpel holder 7 are connected by bolts. The scalpel holder 7 is welded and fixed to the convex arc surface of the arc plate.

[0030] When applied, the stirring paddle 2 of the reactor rotates, causing the water to rotate. Under the action of centrifugal force, the clumps will gradually move towards the reactor wall and be cut and broken up by the linear array of scalpels.
