Description
A dust removal structure for a dental prosthesis processing workbench Technical Field
[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a dust removal structure for a dental prosthesis processing workbench. Background Technology
[0002] Currently, denture grinding is often performed in open environments, generating significant dust and noise pollution, which seriously affects the physical and mental health of dental technicians and students. To alleviate these problems, some denture manufacturing companies and schools have installed large-scale vacuum cleaning equipment in their grinding rooms, which has reduced dust pollution to some extent. However, large-scale vacuum cleaning equipment is expensive, bulky, and difficult to move. Furthermore, it only removes dust that has already diffused into the air, leaving technicians still exposed to dust during operation.
[0003] To address this, existing technologies have proposed mobile denture processing workbenches, such as the mobile denture grinding soundproofing and dust removal workbench with publication number CN203634322U. This workbench features an independent operating chamber with a vacuum cleaner to remove dust generated during denture grinding, providing a better grinding environment. However, after grinding, the denture may require sandblasting to improve its surface smoothness and gloss. The fine sand sprayed out will enter the vacuum cleaner along with the dust, making it difficult to reuse. Summary of the Invention

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0030] As shown in Figures 1-4, the dust removal structure of the dental prosthesis processing workbench of this utility model includes a workbench body 1, a dust collection pipe 2, a cloth bag 3, a filter element 4, and a fan 5.
[0031] The platform 1 is provided with an operating chamber 101 and a dust collection chamber 102. The dust collection chamber 102 is located below the operating chamber 101. The platform 1 is the main frame of the entire technician's table. It is equipped with casters at the bottom for movement. In order to facilitate the user's standing operation, the platform 1 has a vertical structure and a flip cover at the top. Opening the flip cover leads to the operating chamber 101. There are also operation ports on both sides of the platform 1 that connect to the operating chamber 101. In order to facilitate the operation of the operator, a viewing panel is provided on the flip cover, and a partition is provided at the bottom of the operating chamber 101.
[0032] The dust collection pipe 2 is fixed inside the platform 1 and located at the bottom of the operating chamber 101. One end of the dust collection pipe 2 extends into the dust collection chamber 102 and connects the operating chamber 101 and the dust collection chamber 102. The top end of the dust collection pipe 2 is at the same level as the partition and is completely fixed and sealed to the partition by welding or other means. When a negative pressure is formed inside the dust collection pipe 2, the fine sand and dust in the operating chamber 101 can be completely sucked into the dust collection pipe 2 and enter the dust collection chamber 102 through the dust collection pipe 2. Since the fine sand particles are larger than the dust, they may not be completely sucked into the dust collection pipe 2 through the negative pressure. Therefore, the dust collection pipe 2 is set at the bottom of the operating chamber 101 so that the fine sand that cannot be sucked in can still enter the dust collection pipe 2 through the sweeping motion of the operator during cleaning.
[0033] The filter bag 3 is placed inside the dust collection chamber 102 and covers the end of the dust collection pipe 2. The filter bag 3 is used to filter out sand particles in the air. The filter bag 3 has good air permeability, and the fine mesh on it has a pore size smaller than the particle size of fine sand and larger than the particle size of dust. This allows fine sand to be trapped in the filter bag 3, while dust can leave the filter bag 3 through the flow of air. Correspondingly, since the fine sand has a larger mass, it will accumulate in the filter bag 3 under the action of gravity and will not block the mesh of the filter bag 3.
[0034] The filter element 4 is installed in the dust collection chamber 102. The filter element 4 is used to filter out dust in the air. During use, the dust collection chamber 102 has two openings, one of which is connected to the operating chamber 101 and the other is connected to the fan 5. The filter element 4 is installed on the opening of the dust collection chamber 102 connected to the fan 5, so that the air must pass through the filter element 4 before entering the fan 5, thereby achieving the filtration of dust.
[0035] The fan 5 is fixed inside the platform 1, and its input end is connected to the outside of the filter element 4 so that the air in the dust collection chamber 102 flows outward through the filter element 4.
[0036] In this embodiment, by setting a dust collection pipe at the bottom of the operating chamber, the fine sand and dust from the sandblasting process are collected in a unified manner. Then, depending on the size of the fine sand and dust, a cloth bag is used to first filter the fine sand entering the dust collection chamber from the air. Then, the air passes through a filter element to filter out the dust, thereby purifying the air. At the same time, the fine sand is collected for subsequent reuse.
[0037] In some embodiments, a box body 6 is also provided, which is fixed on the platform 1. The box body 6 has an opening on the side facing the outside of the platform 1, and a cover 61 is provided on the opening side. The dust collection chamber 102 is located inside the box body 6, and the filter element 4 is embedded in the side wall of the box body 6. By providing the box body 6, the volume of the dust collection chamber 102 can be effectively reduced, and its sealing effect can be ensured to prevent outside air from directly entering the dust collection chamber 102. At the same time, the cloth bag 3 and filter element 4 inside the dust collection chamber 102 can be replaced or cleaned by opening the cover 61, which makes it more convenient for equipment maintenance and recycling.
[0038] In one embodiment, a connecting cavity 103 is also provided inside the platform 1. The connecting cavity 103 is connected to the dust collection chamber 102 through the filter element 4, and the connecting cavity 103 is connected to the input end of the fan 5. Considering that the filter element 4 cannot be directly connected to the input end of the fan 5, a connecting cavity 103 is provided inside the platform 1, and the fan 5 is connected through the connecting cavity 103. Specifically, the connecting cavity 103 is located on the outside of the filter element 4, so that the filter element 4 is set perpendicular to the horizontal plane. This arrangement allows the air to bend inside the dust collection chamber 102 when the fan 5 draws air from inside the dust collection chamber 102, so as to avoid the situation where fine sand and dust cannot be separated.
[0039] In some embodiments, a mesh cover 7 is also included. The mesh cover 7 is disposed inside the operating chamber 101 and covers the top of the dust collection pipe 2. The mesh cover 7 has a pore size larger than the particle size of fine sand. This arrangement allows fine sand and dust to pass through the mesh cover 7, while items such as polishing pens and dentures are blocked by the mesh cover 7 and will not fall into the dust collection pipe 2 due to improper operation. It should be noted that the mesh cover 7 is made of metal and has a certain wear resistance.
[0040] In some embodiments, the dust collection pipe 2 includes a connecting section 21, a variable diameter section 22, and an installation section 23. The connecting section 21 connects the operating chamber 101 and the dust collection chamber 102. The variable diameter section 22 is located at the bottom of the connecting section 21, and its diameter gradually decreases towards the side away from the connecting section 21. The bottom of the installation section 23 is provided with an outward flange, and the installation section 23 is connected to the cloth bag 3.
[0041] The connecting section 21 is a straight pipe, which mainly connects the operating chamber 101 at the top of the partition to the box 6 below the partition, allowing air to enter the box 6 from the operating chamber 101 through the connecting section 21. The variable diameter section 22 is used to form a narrowing of the connecting section 21. The large end of the variable diameter section 22 has a large cross-sectional area, which is suitable for high flow rate and wide area dust collection, that is, it can cover a wider dust collection space in the operating chamber 101. The outward flange of the mounting end 23 allows the cloth bag 3 to be fixed to the mounting end 23 by tie ropes or cable ties after being put on, and the outward flange prevents it from falling off.
[0042] In some embodiments, the system further includes an installation component 8 disposed on the inner wall of the dust collection chamber 102, the installation component 8 being used to detachably fix the filter element 4 within the dust collection chamber 102.
[0043] Since filter element 4 needs to be cleaned or replaced after long-term use, it cannot be fixed as an integral part of the base body 1. The installation component 8 allows filter element 4 to be removed when cleaning or replacement is needed, making it easier to inspect and maintain.
[0044] Specifically, the installation assembly 8 includes two fixing members 81. The two fixing members 81 are disposed on the side wall of the dust collection chamber 102 and abut against the outer side of the filter element 4, so that the filter element 4 is fixed to the dust collection chamber 102. The fixing members 81 are generally Z-shaped, one end of which is fixed to the platform 1 by screws, and the other end presses the filter element 4.
[0045] Correspondingly, the filter element 4 is provided with a protruding edge 41, which fits against the inner wall of the dust collection chamber 102 and contacts the fixing member 81. The protruding edge 41 of the filter element 4 is provided on its outer frame, and a rubber strip can be embedded in the protruding edge 41. When the filter element 4 is tightly attached to the inner wall of the dust collection chamber 102, the rubber strip can seal the gap between the filter element 4 and the inner wall of the dust collection chamber 102, preventing dust from bypassing the filter element 4 and entering the fan 5.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
