Embodiment 1

[0041] like Figure 1-6 As shown, the present invention provides the aforementioned thermal removal device for extrusion roll sleeves, which includes a bracket 3 , a covering body 4 , a holding pool 5 and a cooling mechanism 6 . The support 3 can be directly installed on the ground, and a part of the storage pool 5 and the pipeline structure 63 can also be arranged on the ground, or a special base can be included, and a part of the support 3, the storage tank 5 and the pipeline structure 63 can be set on the base.

[0042] The upper part of the support 3 is a support ring 31, the diameter of the inner hole of the support ring 31 is larger than the outer diameter of the tubular structure formed by the roller shaft 2 and the heat conducting sheet 7, and a ring is provided on the support 3 that is concentric with the inner hole and is connected to the outer surface of the covering body 4. Locating grooves for radial fit. In this way, it is convenient to place and position the c...

Embodiment 2

[0050] like Figure 3-6 As shown, the structural difference between this embodiment and Embodiment 1 is that a placement tube 51 is fixed at the bottom of the holding pool 5, the placement tube 51 is located below the lower atomizing nozzle 62, and the inner hole of the placement tube 51 Corresponding to the lower part of the roller shaft 2, a buffer mechanism is provided at the bottom of the inner hole. The buffer mechanism can be any existing buffer device, such as a spring plate with a built-in spring, a buffer pad made of elastic material, or an air pressure or hydraulic buffer device. . In this solution, the roller shaft 2 is caught by the placement tube 51, the pair of the roller shaft 2 is placed to topple over, and the impact of the falling of the roller shaft 2 is absorbed by the buffer mechanism to prevent the roller shaft 2 from being damaged. It is more convenient not to use hoisting equipment at the same time when heating.

[0051] As for the thermal removal dev...

Abstract

The invention discloses an extrusion roller sleeve heating disassembly device and a disassembly method using the extrusion roller sleeve heating disassembly device. The extrusion roller sleeve heatingdisassembly device includes a support, a coating body, a containing pool and a cooling mechanism. The upper portion of the support is provided with a support ring; the coating body coasts the exterior of a roller sleeve and is placed on the support ring, and a heating mechanism is arranged inside the coating body; the containing pool is formed in the lower portion of an inner hole of the supportring and is used for containing the roller sleeve; the cooling mechanism includes a cooling support, an atomization spray nozzle, a pipeline structure and a liquid storage tank, cooling water is stored in the liquid storage tank, and the liquid storage tank is provided with a cooling pump connected with the pipeline structure. Compared with a cutting method, by adopting the extrusion roller sleeveheating disassembly device and the disassembly method using the extrusion roller sleeve heating disassembly device to disassemble the roller sleeve, the production efficiency is improved, the disassembly time is shortened, the disassembled roller sleeve can still be in use as required after the surface of the roller sleeve is repaired, the roller sleeve cannot be damaged, and defects of the priorart are overcome.

Description

technical field [0001] The invention relates to the field of cement production, in particular to a heat dismantling device for extrusion roller sleeves and a dismantling method using the device. Background technique [0002] In the field of cement production, after the squeeze roll has been used for a period of time, the sleeve of the squeeze roll will be easily worn, so it needs to be replaced and repaired regularly. To maintain subsequent production, faster replacement of the sleeves is required. In the prior art, many squeeze roller shafts and roll sleeves are assembled together through interference fit. During the maintenance process, due to the large interference between the roll shaft and the roll sleeve, it is difficult to disassemble. Usually, cutting the roll sleeve with The separation of the roller shaft and the roller sleeve is relatively inefficient, and the roller shaft will inevitably be cut during the cutting process. Contents of the invention [0003] The...
