Description

Technical Field

[0001] The utility model relates to the technical field of single crystal furnace cleaning, in particular to a single crystal furnace disassembly and dust removal filtering tool. Background Art

[0002] During the single crystal pulling process in a single crystal furnace, graphite parts, quartz parts, insulation felt and other thermal field components are required to maintain normal melting and crystal pulling processes within the furnace. During the production process, a large amount of oxides will adhere to the furnace. During operation, the components within the furnace will also suffer varying degrees of damage, resulting in the generation of slag. Therefore, after each furnace operation, the furnace is dismantled and cleaned. During this cleaning process, oxides and component slag are suctioned out using a high-negative pressure vacuum system.

[0003] At present, the existing dismantling and dust removal operation method is that oxides and debris enter the dust removal treatment system directly through the dust suction and dust removal pipeline. Larger debris can easily cause blockage and damage to the internal filter element of the dust removal treatment system, making the dust removal treatment system operate poorly. To ensure its normal operation, it is necessary to frequently stop and replace the filter element, resulting in increased filter element replacement costs. If a sudden device trip occurs, it is very easy to affect personnel safety, the dust removal treatment system or the production of single crystal furnaces. Utility Model Content

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection, indirect connection through an intermediate medium, or internal communication between two elements or interaction between two elements. Those skilled in the art can understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the utility model discloses a single crystal furnace disassembly and dust removal filtering tool, including a shell 1, the shell 1 is in a rectangular parallelepiped, and a foldable handle 4 is provided on the top of the shell 1. The tool can be lifted and moved by the handle 4, and the handle 4 can be folded when not in use.

[0030] A filter inlet cannula 2 is provided at one end of the top of the shell 1, and the filter inlet cannula 2 is connected to the dust collection pipe. A filter outlet cannula 3 is provided on the top of the side wall of the shell 1 away from the filter inlet cannula 2, and the filter outlet cannula 3 is connected to the dust removal pipe.

[0031] A filter assembly 6 is provided in the shell 1 and is located between the filter inlet cannula 2 and the filter outlet cannula 3. Debris is sucked into the dust collection pipe and enters the shell 1 through the filter inlet cannula 2. Larger debris in the debris is intercepted by the filter assembly 6, and the remaining debris follows the airflow into the dust removal pipe through the filter outlet cannula 3 and then into the dust removal processing system. The filter assembly 6 prevents larger debris from entering the dust removal processing system and causing damage to the system.

[0032] The filter assembly 6 includes a filter frame 61 arranged in the shell 1. The top end of the filter frame 61 is connected to the top of the shell 1, and the bottom end of the filter frame 61 is connected to the side wall of the shell 1 below the filter outlet cannula 3. The filter frame 61 is arranged at an angle, and its top end is inclined toward the side away from the filter outlet cannula 3.

[0033] The inner wall of the filter frame 61 is provided with a circle of chutes. The side edge where the top of the filter frame 61 is connected to the housing 1 is provided with an inner slot. The top of the housing 1 above the inner slot is provided with an outer slot that matches the inner slot. A screen plate 62 is provided to slide inside the filter frame 61. The screen plate 62 is covered with a number of sieve holes. The size of the screen plate 62 matches the chutes of the filter frame 61. The screen plate 62 can slide into the chutes of the filter frame 61 through the outer and inner slots. The top of the screen plate 62 is located outside the outer slot. The top of the screen plate 62 is provided with a bend 63, which facilitates the extraction of the screen plate 62 from the filter frame 61. A circle of gasket is provided on the edge of the screen plate 62 that contacts the slide groove and the inner groove. The gasket has a certain elasticity and can be made of sponge or rubber. The gasket not only increases the sealing between the edge of the screen plate 62 and the filter frame 61, but also appropriately increases the friction between the gasket and the filter frame 61 to prevent the screen plate 62 from sliding in the filter frame 61 under the action of airflow.

[0034] In this embodiment, the number of filter components 6 is one, and the number of filter components 6 can be increased according to the situation. The mesh sizes of the screen plates 62 of multiple groups of filter components 6 gradually decrease in the airflow direction.

[0035] An opening assembly 5 is provided at the bottom of the side wall of the shell 1 opposite to the filter outlet cannula 3. The opening assembly 5 can be closed to achieve sealing inside the shell 1, and can be opened to clean up larger debris filtered out by the filter assembly 6 in the shell 1.

[0036] The opening assembly 5 includes a rectangular cleaning port 51 opened on the shell 1, a cleaning door 52 is provided in the cleaning port 51, and a circle of sealing strip 53 is provided on the inner wall where the cleaning door 52 contacts the edge of the cleaning port 51. The sealing strip 53 seals the cleaning door 52 and the cleaning port 51.

[0037] One end of the cleaning door 52 is provided with a hinge 54 connected to the shell 1 at the edge of the cleaning port 51, and the hinge 54 is used to realize the hinge connection between the cleaning door 52 and the cleaning port 51. A buckle 55 is provided between the other end of the cleaning door 52 and the shell 1 at the edge of the cleaning port 51, and the cleaning door 52 and the cleaning port 51 are opened and closed by the buckle 55.

[0038] When dismantling the furnace for cleaning, connect the filter inlet cannula 2 to the dust collection pipe, connect the filter outlet cannula 3 to the dust removal pipe, and then carry out dust collection and dust removal. The debris in the furnace is sucked in and enters the shell 1 through the dust collection pipe. The larger debris in the debris is filtered by the screen plate 62 to prevent it from entering the subsequent dust removal system. Since the screen plate 62 is tilted, the larger debris filtered out is not easy to adhere to the screen plate 62, and the larger debris falls into the shell 1 under its own gravity. After the dismantling of the furnace for cleaning is completed, open the buckle 55, open the cleaning door 52, and clean the larger debris filtered out in the shell 1. The screen plate 62 in the filter frame 61 can be pulled out through the bending portion 63. After cleaning the debris attached to the screen plate 62, it can be inserted into the filter frame 61 through the outer slot and the inner slot for reuse.

[0039] The utility model is directly placed between the dust suction duct and the dust removal duct, and pre-filters the debris sucked in the furnace before entering the dust removal treatment system, and filters the larger debris that may cause damage to the dust removal treatment system in advance, ensuring the normal operation of the dust removal treatment system, without the need to frequently stop and replace the filter element, avoiding sudden device shutdown, and the filtered debris can be directly poured out from the cleaning port 51, and the screen plate 62 can be directly extracted from the filter frame 61 for cleaning. After cleaning, it can be inserted into the filter frame 61 for reuse. The cleaning operation is simple and fast, the tool structure is simple, the production and use costs are low, and it is easy to use.

[0040] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention.
