Description

Technical Field

[0001] This utility model relates to the field of sediment separation technology by additional centrifugal force, and in particular to a pressure-resistant reinforcement device for the shell of a high-concentration slag remover. Background Technology

[0002] A slag remover is a device that uses centrifugation to remove impurities from slurry that have a density different from that of the slurry. The upper part of the slag remover is made of stainless steel, and the lower part is made of polyurethane material through injection molding. The inner wall of the main body is designed as a spiral cone.

[0003] When high-concentration slurry rotates at high speed inside the slag remover, the shell needs to withstand combined radial and axial pressures. Stress concentration is particularly likely to occur in local areas of the shell. Under the action of centrifugal force, the slurry adheres tightly to the inner wall of the shell, forming a radially outward pressure gradient. The magnitude of this gradient is proportional to the slurry density, the square of the rotation speed, and the radius, reaching its peak at the maximum diameter of the shell. This makes the shell prone to plastic deformation under high pressure conditions. Therefore, we propose a pressure-resistant reinforcement device for the shell of a high-concentration slag remover. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a pressure-resistant reinforcement device for the shell of a high-concentration slurry remover. This device can solve the problem that when high-concentration slurry rotates at high speed in the slurry remover, the shell needs to withstand the combined radial and axial pressure, especially in local areas of the shell where stress concentration is likely to occur. Under the action of centrifugal force, the slurry adheres tightly to the inner wall of the shell, forming a radially outward pressure gradient. The magnitude of this gradient is proportional to the slurry density, the square of the rotation speed, and the radius, reaching its peak at the maximum diameter of the shell. This makes the shell prone to plastic deformation under high pressure conditions.

Multiple locking plates are fixedly connected to the side of the second reinforcement space frame closest to the first reinforcement space frame, and multiple locking plates are fixedly connected to the side of the first reinforcement space frame closest to the second reinforcement space frame. Each locking plate has a through hole at its top, with two corresponding through holes fitted together. Multiple bolts pass through these two corresponding through holes, and the locking plates are installed using corresponding bolts.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a pressure-resistant reinforcement device for a high-concentration slag remover shell, comprising:

[0027] Support platform 1, the top of support platform 1 is bolted with slag remover shell body 7, the bottom end of slag remover shell body 7 passes through support platform 1 and is fixedly connected to slag collection cylinder 2;

[0028] A shell reinforcement structure is located on the support platform 1;

[0029] The shell reinforcement structure includes a first reinforcement frame 10, a second reinforcement frame 11, multiple bolts 15, and four main support plates 5. The four main support plates 5 are all bolted to the top of the support platform 1, and screws are set at the bottom of the support platform 1 to fix the main support plates 5. Support side plates 6 are fixedly connected to both sides of the four main support plates 5. The first reinforcement frame 10 and the second reinforcement frame 11 are fixedly connected to the corresponding two main support plates 5. The first reinforcement frame 10 is hinged to the second reinforcement frame 11. Multiple locking plates 2 12 are fixedly connected to the side of the second reinforcement frame 11 near the first reinforcement frame 10. Multiple locking plates 1 13 are fixedly connected to the side of the first reinforcement frame 10 near the second reinforcement frame 11. The top of the multiple locking plates 1 13 and the multiple locking plates 2 12 are all provided with through holes 14, and the two corresponding through holes 14 are fitted together. Multiple bolts 15 pass through the two corresponding through holes 14. The multiple locking plates 2 12 and the multiple locking plates 1 13 are installed by the corresponding bolts 15.

[0030] The top of the slurry outlet pipe 8 is fixedly connected to the shell body 7 of the slag remover. The inlet pipe 9 is fixedly connected to the outer surface of the shell body 7 of the slag remover.

The first reinforcing mesh frame 10 and the second reinforcing mesh frame 11 are connected by hinges and bolts 15 to form a complete reinforcing ring around the main body 7 of the slag remover shell. When the pressure inside the shell increases, the mesh frame initially disperses the pressure, and then the pressure is dispersed to the support platform 1 through the main support plates 5 to reduce the local stress of the shell.

[0032] When disassembling the grid frame, first remove the four supporting main plates 5. Locking plate 13 and locking plate 2 12 can be separated by removing bolts 15, thereby separating the reinforcing grid frame 10 and reinforcing grid frame 2 11 for quick disassembly.

Impurities are gathered to the slag collection cylinder 2 due to centrifugal force, and good slurry is discharged through the top good slurry outlet pipe 8. The gate valve 1 3 and gate valve 2 4 are activated to control the slag discharge process. The sight glass is used to monitor the slag discharge in real time.

[0033] The complete reinforcing ring formed by the reinforcing space frame 10 and the reinforcing space frame 2 11, together with the frame structure of the supporting main board 5 and the supporting side plate 6, effectively disperses the radial and axial composite pressure generated by the rotation of high-concentration slurry, alleviates the problem of local stress concentration in the shell, avoids plastic deformation of the shell due to high pressure, and improves the structural reliability of the shell under high-concentration and high-pressure conditions.
