Description

Technical Field

[0001] The utility model belongs to the technical field of underground buildings, and in particular relates to a sintering furnace filtering device. Background Art

[0002] Pressure sintering is one of the main production methods of powder metallurgy and metal ceramics. During the sintering process, the gas precipitated on the surface of the product will undergo a process of transformation from gas to liquid under the action of a specific forming agent. The transformed liquid will be discharged from the furnace through a certain path and method, commonly known as "dewaxing". At the same time, in the entire dewaxing process, if the filtering device is not effective, there will often be problems such as incomplete wax gas filtration, wax accumulation in the filtering device and complicated cleaning.

[0003] Therefore, how to improve the filtering effect during the dewaxing process of the sintering furnace and solve the complicated problem of cleaning the wax accumulation in the filtering device are issues that need to be solved urgently. Utility Model Content

[0007] The filter cartridge is installed in each of the dewaxing pipelines, and the ball ring is arranged in each of the filter cartridges.

[0008] As a further improvement, a cleaning cover plate handle is provided at one end of each layer of the dewaxing pipeline.

[0009] As a further improvement, a filter cartridge cover handle is provided at one end of each layer of the filter cartridge close to the cleaning cover handle.

[0010] As a further improvement, the dewaxing pipelines of each layer are arranged to be connected and inclined from top to bottom in sequence.

[0011] As a further improvement, the inclination angle between the dewaxing pipes of two adjacent layers is 5°-10°.

[0015] The beneficial effects of the utility model are:

[0016] 1. By connecting the dewaxing pipeline and the filter cartridge inside the dewaxing pipeline in an inclined manner from top to bottom, the gas filtration path becomes longer and more complicated, thereby achieving a better filtration effect; and the filtration volume of the filtration device is increased under the same installation space, thereby enhancing the filtration efficiency of the gas, and is not prone to paraffin accumulation and blockage.

[0017] 2. By arranging a filter cartridge inside the dewaxing pipeline, arranging a ball ring inside the filter cartridge and arranging a filter cartridge cover handle on the filter cartridge, it is achieved that when the filter device needs to be cleaned, it is only necessary to twist the cleaning cover handle corresponding to the dewaxing pipeline, and then pull the filter cartridge cover handle corresponding to the filter cartridge to conveniently drag out all the ball rings in the filter cartridge, and then clean the entire filter, avoiding the traditional cleaning process of removing the ball rings one by one with tools, facilitating the cleaning of the entire filter device, saving the cleaning time of the filter device, and reducing the production and maintenance costs.

[0025] Reference Figure 1-2 As shown, this embodiment provides a sintering furnace filtering device, comprising:

[0026] A filter assembly 1, the filter assembly 1 comprising a dewaxing pipeline 2, a filter cartridge 3 and a ball ring 4, the front end of the dewaxing pipeline 2 is provided with an air inlet 5, the end of the dewaxing pipeline 2 is provided with an exhaust port 6, the dewaxing pipeline 2 is provided with at least four layers from top to bottom, and each group of two adjacent layers of the dewaxing pipeline 2 are connected;

[0027] The filter cartridge 3 is installed in the dewaxing pipeline 2 , and the ball ring 4 is arranged in the filter cartridge 3 .

[0028] A support frame 9 is used to install the filter assembly 1.

[0029] In this embodiment, the dewaxing pipeline 2 is provided with four layers. Such a configuration can ensure that the space occupied by the filtering device is small while ensuring that the dewaxing pipeline 2 of the filtering device has a longer path, thereby improving the filtering effect of paraffin.

[0030] Furthermore, the dewaxing pipelines 2 of each layer are arranged to be connected and tilted in sequence from top to bottom, and the tilt angle between the dewaxing pipelines 2 of two adjacent layers is 5°-10°.

[0031] Furthermore, each layer of the filter cartridges 3 is tilted from top to bottom, and the tilt angle between two adjacent layers of the filter cartridges 3 is 5°-10°.

[0032] When the inclination angle between two adjacent groups of dewaxing pipes 2 is less than 5°, paraffin accumulation and blockage may occur easily; when the inclination angle between two adjacent groups of dewaxing pipes 2 is greater than 10°, incomplete paraffin filtration may occur easily. Therefore, in this embodiment, the inclination angle between the two adjacent groups of dewaxing pipes 2 is set to 8°. This setting can ensure that paraffin can pass through the inside of the dewaxing pipes 2 smoothly, and paraffin accumulation and blockage may not occur easily, and can also ensure better paraffin filtration effect.

[0033] By arranging the dewaxing pipeline 2 and the filter cartridge 3 located inside the dewaxing pipeline 2 in an inclined manner from top to bottom, the gas filtration path becomes longer and more complicated, thereby achieving a better filtration effect; and the filtration volume of the filtration device is increased under the same installation space, thereby enhancing the gas filtration efficiency and not easily causing paraffin accumulation and blockage.

[0034] Furthermore, a cleaning cover plate handle 7 is provided at one end of each layer of the dewaxing pipeline 2 .

[0035] Furthermore, a filter cartridge cover handle 8 is provided at one end of each layer of the filter cartridge 3 close to the cleaning cover handle 7 .

[0036] By arranging a filter cartridge inside the dewaxing pipe 2, arranging a ball ring 4 inside the filter cartridge and arranging a filter cartridge cover handle 8 on the filter cartridge, it is achieved that when the filter device needs to be cleaned, it is only necessary to twist the cleaning cover handle 7 corresponding to the dewaxing pipe 2, and then pull the filter cartridge cover handle 8 of the corresponding filter cartridge to conveniently drag out all the ball rings 4 in the filter cartridge, and then clean the entire filter, avoiding the traditional cleaning process of removing the ball rings 4 one by one with tools, facilitating the cleaning of the entire filter device, saving the cleaning time of the filter device, and reducing the production and maintenance costs.

[0037] Compared with the traditional cleaning method, that is, taking out the ball rings 4 one by one by using tools, the cleaning method in this embodiment facilitates the cleaning of the entire filter device, saves the cleaning time of the filter device, and reduces the production and maintenance costs.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
