Description

Technical Field

[0001] This invention relates to the field of material grinding and powder production technology, and more specifically to a detachable connecting shaft cylinder and a screw conveyor having thereon. Background Technology

[0002] The double-inlet, double-outlet steel ball mill contains a certain number of steel balls inside its cylinder. When the cylinder rotates, the steel balls inside the cylinder tumble and grind the material inside the cylinder into fine powder. The screw conveyor is installed at both ends of the cylinder. The auger is the core component of the screw conveyor. The inner end of the auger is connected to the cylinder through a support rod assembly, and the outer end is fixed in the bearing seat through a rotating shaft. The auger rotates synchronously with the cylinder, and the spiral blades on the auger push the material at the hollow shaft in the cylinder into the cylinder.

[0003] To ensure the auger blades effectively push material into the cylinder, the gap between the auger blades and the bushing must be less than 10mm, and there must be no interference with the bushing. This requires the coaxiality of the auger centerline and the cylinder centerline to be within 5mm. The left end of the auger centerline is adjusted using the support rod assembly, and the right end is adjusted using the auger bearing seat. After adjustment, the support rod assembly is welded and fixed to the support rod mounting sleeve. During installation, there is no actual reference point inside the cylinder, making the adjustment of the auger centerline within the cylinder very difficult and labor-intensive. When the auger needs replacement due to auger blade wear or chain breakage, the support rod assembly must be cut, and the auger removed from the cylinder for repair. Reinstallation requires readjusting and aligning the auger centerline, making the replacement process cumbersome and inefficient.

[0004] Therefore, how to provide a screw conveyor that is simple in structure, easy to operate, allows the auger to be easily pulled out of the cylinder when maintenance is needed, and does not require readjustment of the center line during reassembly, thus improving replacement efficiency, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a detachable connecting shaft cylinder and a screw conveyor having the same, aiming to solve the above-mentioned technical problems.

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

[0007] A detachable connecting shaft sleeve, comprising:

[0008] A collar; the collar includes multiple arc plates, and two adjacent arc plates are fixedly connected by an arc-shaped mounting plate; each arc mounting plate has a notch and slot on one end facing its inner wall, and the notch and slot form a positioning mounting groove with the side edges of two adjacent arc plates, and the notch and slot has a threaded hole.

[0009] Sleeve; the end face of one end of the sleeve has a plurality of spaced and axially extended retaining plates, the retaining plates are embedded in the positioning and mounting groove, and the retaining plates have a first bolt hole corresponding to the threaded hole;

[0010] A snap-fit ​​component; the snap-fit ​​component is embedded in the positioning and mounting groove, and the snap-fit ​​component has a second bolt hole corresponding to the first bolt hole. The fastener passes through the second bolt hole and the first bolt hole in sequence and is fastened to the threaded hole.

[0011] Preferably, in the above-mentioned detachable connecting shaft sleeve, the end faces of the arc plate and the arc mounting plate are flush; the inner sidewall of each arc plate has a mounting surface that abuts against the edge of the sleeve, and the edge of the retaining plate abuts against the end face of the notch groove.

[0012] Preferably, in the above-mentioned detachable connecting shaft cylinder, the inner wall of the arc plate is a first arc surface, and the inner wall of the notch slot is a second arc surface; the arc radii of the first arc surface and the second arc surface are equal.

[0013] Preferably, in the above-mentioned detachable connecting shaft cylinder, the outer arc surface of the clamping plate is a third arc surface, and the third arc surface abuts against the second arc surface.

[0014] Preferably, in the above-mentioned detachable connecting shaft cylinder, one end face of the snap-fit ​​member is a plane, and the other end face is a fourth arc surface that is adapted to the third arc surface.

[0015] Preferably, in the above-mentioned detachable connecting shaft cylinder, the number of the arc plate, the arc mounting plate, the clamping plate, and the positioning mounting groove are all multiple and the number is the same.

[0016] The present invention also provides a screw conveyor, comprising:

[0017] cylindrical body;

[0018] The housing consists of two shells, each connected to an opening at one end of the cylinder. Each shell has a feed inlet and a fixed hot air box, with a bearing seat installed inside the hot air box. A detachable connecting shaft is coaxially arranged within the shell. A spiral blade is fixed to the outer wall of the shaft via a chain. The end of the shaft furthest from the collar is rotatably connected to the bearing seat via a rotating shaft. The arc-shaped mounting plate on the collar is connected to the inner wall of the cylinder via a support rod assembly.

[0019] Preferably, in the above-mentioned screw conveyor, the arc-shaped mounting plate has a through hole, one end of the support rod assembly is fixedly connected to the arc-shaped mounting plate through the through hole, and the other end is fixedly connected to the inner wall of the cylinder.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a detachable connecting shaft cylinder and a screw conveyor having the same, which has the following beneficial effects:

[0021] 1. The connection structure of the collar and sleeve of the present invention is simple and easy to install and disassemble.

[0022] 2. This invention, through the detachable connection of the collar and sleeve, allows for the separation of the collar and sleeve when problems such as wear of the spiral blades or breakage of the chain occur. This enables the sleeve with the spiral blades and chain to be pulled out of the cylinder, while the collar and support rod assembly remain inside. This solves the technical problem in existing technologies where the support rod assembly must be cut to remove the collar and sleeve from the cylinder, saving on support rod assembly wear. After repair, when the sleeve is reinstalled into the cylinder, it can be secured by the collar and sleeve using the snap-fit ​​mechanism, eliminating the need for readjustment of the center line, saving working time and improving work efficiency.
