Description

Technical Field

[0001] The utility model relates to a dust removal mechanism and processing equipment, in particular to a dust removal mechanism and processing equipment which can remove dust at a cabin door position. Background Art

[0002] Existing crystals are prone to produce a lot of debris and dust during processing. After the crystal processing is completed, the moment the operator opens the equipment hatch, a large amount of dust in the hatch overflows, causing a large amount of ultrafine dust to float in the air, causing the powder concentration in the entire workshop to rise sharply. A large amount of exposed powder can cause damage to the equipment and the environment, and operators inhaling a large amount of dust can easily induce a variety of diseases, which in turn affects their health. If the dust concentration in the workshop is too high, it may also cause an explosion accident after contact with open flames, posing a great safety hazard. Therefore, it is crucial to control the dust concentration in the workshop during the crystal processing process.

[0003] For crystal cutting equipment, when the hatch is opened, the dust concentration near the hatch can reach 800μg / m3~1000μg / m3. Existing cutting equipment usually uses spraying to cool down and remove dust during operation to effectively avoid the dust inside the closed equipment from being raised. At the same time, the cutting equipment has an exhaust device connected to the main exhaust pipe, which can promptly inhale the dust generated during the cutting process. The above two dust removal methods interact with each other and can remove dust while the cutting equipment is running.

[0004] After the hatch is opened, since the exhaust pipes in the cutting equipment are thin and the air extraction volume is small, even if the dust removal air volume of the equipment itself is increased, negative pressure cannot be formed near the hatch when the hatch is opened, and dust overflow cannot be avoided, causing the operator to directly contact a large amount of powder, which in turn endangers their health. Utility Model Content

[0005] The purpose of the utility model is to provide a dust removal mechanism and processing equipment. After the dust removal mechanism is turned on, it can form a local negative pressure environment near the cabin door, and then suck the dust overflowing from the cabin door when the cabin door is opened. The dust reduction effect is obvious, which can avoid the operator from direct contact with the dust when opening the cabin door, thereby reducing or even avoiding the harm of dust to the operator's body.

[0006] To achieve the above-mentioned purpose, the utility model provides a dust removal mechanism, including an air suction port, an air guide channel and a negative pressure fan connected in sequence, and the distance between the air suction port and the edge of the hatch of the equipment body is less than a preset value.

[0007] Optionally, the position of the air suction port corresponds to the position of the edge of the hatch.

[0008] Optionally, the distance between the air suction port and the edge of the cabin door is less than 500 mm.

[0009] Optionally, the air suction port is fixed on the outer wall or inner wall of the device body.

[0012] Optionally, there are multiple branch pipelines, and the multiple branch pipelines are connected in sequence; the main pipeline is connected to at least one branch pipeline.

[0013] Optionally, the number of the branch pipes is three, the three branch pipes are connected in sequence to form a U-shaped structure, and the three branch pipes surround the cabin door.

[0014] Optionally, there are multiple air guide channels, each of which cooperates with a corresponding cabin door, and all of the air guide channels are connected to the negative pressure fan.

[0015] To achieve the above-mentioned purpose, the utility model also provides a processing equipment, including an equipment body and any one of the dust removal mechanisms described above, wherein the dust removal mechanism is arranged on the equipment body and is used to inhale substances overflowing from the hatch of the equipment body.

[0016] The utility model provides a dust removal mechanism and processing equipment, the processing equipment includes an equipment body and a dust removal mechanism arranged on the equipment body. The dust removal mechanism includes an air suction port, an air guide channel and a negative pressure fan connected in sequence, and the distance between the air suction port and the edge of the hatch of the equipment body is less than a preset value.

At the same time, the setting of the dust removal mechanism can also prevent the operator from directly contacting a large amount of dust when opening the hatch, thereby reducing or even avoiding the damage of the dust to the operator's body.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0022] The orientation or position relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be directly connected or connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In the description of the present invention, the meaning of "multiple" is at least two, such as two or three or more, etc.

[0024] In the prior art, specific measures to reduce dust concentration in processing equipment and workshops include:

[0025] 1. Add a dust hood near the door of the processing equipment to exhaust all the dust through the newly added exhaust duct and dust exhaust fan to avoid powder spillage after opening the door. This method requires the reconstruction of the processing equipment and dust removal system, which is very expensive.

[0026] 2. Add a gas circulation device in the workshop to discharge the dusty air in the workshop in time to prevent the dust from staying in the air. This method requires adding a fresh air system in the workshop, which also increases cost investment and energy consumption, and the dust removal effect is limited.

[0027] 3. Place an air purifier in the workshop to absorb the dust in the workshop. This solution will also greatly increase the investment and maintenance costs, and the dust removal effect is limited.

[0028] Although the above methods can improve and reduce the amount of dust in the workshop environment to a certain extent, it is difficult to prevent dust from escaping from the processing equipment at the source. In addition, since the dust will stay near the hatch for a period of time after the hatch is opened, it is impossible to prevent the operator from directly contacting the dust.

[0029] The present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the case of not conflicting with existing dust removal facilities, the following embodiments and features in the embodiments can complement or be combined with each other.

[0030] See also Figure 1 and Figure 2 As shown, a preferred embodiment of the utility model provides a dust removal mechanism 1, comprising an air suction port 11, an air guide channel 12 and a negative pressure fan 13 connected in sequence. The distance between the air suction port 11 and the edge of the hatch 21 (i.e., the frame of the hatch 21) is less than a preset value, that is, the air suction port 11 is arranged adjacent to the hatch 21 of the device body 2. The negative pressure fan 13 is used to form a negative pressure at the position of the hatch 21 through the air suction port 11, so that the dust removal mechanism 1 inhales dust overflowing from the hatch 21.

[0031] In a preferred embodiment, the position of the air suction port 11 corresponds to the position of the edge of the cabin door 21. At this time, the distance between the air suction port 11 and the edge of the cabin door 21 (i.e., the frame of the cabin door 21) is approximately zero, and the air suction port 11 is arranged close to the edge of the cabin door 21.

[0032] In a preferred example, the preset value is 500 mm, that is, the distance between the air suction port 11 and the edge of the door 21 is less than 500 mm. Of course, in other examples, the preset value may also be greater than 500 mm. The preset value here can be set according to actual conditions, and the specific value of the preset value only needs to ensure that the dust removal mechanism 1 can basically suck the dust overflowing from the door 21 through the air suction port 11.

[0033] It should be explained that the smaller the distance between the air suction port 11 and the edge of the door 21, that is, the smaller the preset value, the better the suction effect of the dust removal mechanism 1. Therefore, when the air suction port 11 is set at the edge of the door 21, the dust removal mechanism 1 has a better suction effect.

[0034] Continue to refer to Figure 1As shown, a preferred embodiment of the utility model further provides a processing device, including a dust removal mechanism 1 and a device body 2, wherein the dust removal mechanism 1 is arranged on the device body 2 and is used to absorb substances overflowing from the hatch 21 of the device body 2. It should be understood that the substance refers to debris or dust overflowing from the hatch 21 of the device body 2 and capable of being sucked by the dust removal mechanism 1.

[0035] In the dust removal mechanism 1 and processing equipment provided in the present application, since the air suction port 11 of the dust removal mechanism 1 is arranged near the hatch 21 of the equipment body 2, the dust removal mechanism 1 can form a negative pressure environment near the hatch 21 after it is opened. At this time, the dust overflowing from the cabin of the equipment body 2 is sucked into the dust removal mechanism 1 together with the surrounding air, and a large amount of air near the equipment body 2 is supplemented to the position of the hatch 21, making it difficult for the powder in the cabin to overflow, and the dust reduction effect is obvious, which effectively maintains the operating environment of the workshop. At the same time, the setting of the dust removal mechanism 1 can also prevent the operator from directly contacting a large amount of dust when opening the hatch, thereby reducing or even avoiding the harm of dust to the operator's body.

[0036] It should be noted that the application field of the processing equipment in this application is not limited to crystal processing, and the processing equipment can also be applied to mechanical processing or other material cutting fields. In addition, the application scenarios of the processing equipment are not limited to crystal cutting, but can also be applied to application scenarios such as material grinding, welding, and polishing. Generally speaking, any processing equipment that generates dust during processing can use the dust removal mechanism 1 for dust removal.

[0037] Since the present application does not involve improvements to the device body 2, those skilled in the art can determine the type of the device body 2 according to the operating conditions, which will not be described in detail here.

[0038] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the air inlet 11, the air guide channel 12 and the negative pressure fan 13 are all arranged on the outer wall 22 of the device body 2. In this way, the dust removal mechanism 1 can be added to the device body 2 without changing the structure of the original device body 2, thereby improving the dust removal effect and reducing the equipment modification cost, which has a high economic benefit.

[0039] In another preferred embodiment, the air suction port 11, the air guide channel 12 and the negative pressure fan 13 can also be respectively arranged on the inner wall (unnumbered) and / or the outer wall 22 of the equipment body 2 as needed.

[0040] In a preferred example, the air suction port 11 is fixed on the outer wall 22 of the device body 2. Specifically, the air suction port 11 can be set on the outer wall 22 of the device body 2 at a position adjacent to the hatch 21, that is, the air suction port 11 is set on the outer wall 22 of the device body 2 near the hatch 21. In another preferred example, the air suction port 11 is fixed on the inner wall of the device body 2. Specifically, the air suction port 11 can also be set on the inner wall of the device body 2 at a position adjacent to the hatch 21, that is, the air suction port 11 is set on the inner wall of the device body 2 near the hatch 21.

[0041] The present application does not limit the location of the suction port 11, and the suction port 11 only needs to be located near the door 21 to facilitate the suction of dust near the door 21. It can be foreseen that the technical solution of the suction port 11 being located near the door 21 should be included in the scope of protection of the present utility model.

[0042] like Figure 1 As shown, the dust removal mechanism 1 also includes an exhaust pipe 14, which is connected to a negative pressure fan 13. After the dust in the cabin of the equipment body 2 is sucked into the air guide channel 12 through the air suction port 11, it can be discharged from the exhaust pipe 14 under the action of the negative pressure fan 13.

[0043] Continue to refer to Figure 1 In a preferred embodiment, the air guide channel 12 includes a main pipeline 121 and a branch pipeline 122. One end of the main pipeline 121 is connected to the branch pipeline 122, and the other end is connected to the negative pressure fan 13. The branch pipeline 122 is disposed adjacent to the cabin door 21.

[0044] In a specific embodiment, the branch pipe 122 is fixedly connected to the equipment body 2. For example, the branch pipe 122 can be fixed at a position corresponding to the hatch 21 in the inner wall or outer wall 22 of the equipment body 2, that is, the branch pipe 122 is fixed at a position close to the edge of the hatch 21, so that the distance between the air intake port 11 and the edge of the hatch 21 is less than a preset value.

[0045] Furthermore, the branch pipeline 122 is provided with an air suction port 11 , in which case the air suction port 11 may be provided as a through hole on the branch pipeline 122 , or the air suction port 11 may be provided as a pipe fitting connected to the branch pipeline 122 .

[0046] During actual use, after the negative pressure fan 13 is turned on, the dust near the hatch 21 of the equipment body 2 can be sucked in through the air intake 11, and discharged from the exhaust pipe 14 after passing through the branch pipeline 122 and the main pipeline 121 in sequence.

[0047] Preferably, when there are multiple branch pipelines 122, each branch pipeline 122 is provided with a plurality of air suction ports 11, and all the air suction ports 11 can be arranged along an axis parallel to the edge of the cabin door 21 to enhance the dust removal effect of the dust removal mechanism 1.

[0048] It should be noted that when there are multiple branch pipelines 122, each branch pipeline 122 can be directly connected to the main pipeline 121, or each branch pipeline 122 can also be indirectly connected to the main pipeline 121 through other branch pipelines 122. The present application does not limit the connection method between the main pipeline 122 and the branch pipeline 122 in the air guide channel 12. The connection between the main pipeline 121 and the branch pipeline 122 in the air guide channel 12 only needs to satisfy the requirement that the dust sucked from the air inlet 11 on the branch pipeline 122 can be introduced into the exhaust pipe 14 through the main pipeline 121.

[0049] It should also be noted that the air guide channel 12 may also include only one of the main line 121 and the branch line 122. For example, the air guide channel 12 may include only the main line 121, and the air inlet 11 may be set on the main line 121. For another example, when there are multiple air guide channels 12, some of the air guide channels 12 may also include only the branch line 122, and the branch line 122 of the air guide channel 12 may be connected to the main line 121 of other air guide channels 12 or the branch line 122 of other air guide channels 12 to form a dust discharge channel. The specific structure of the air guide channel 12 is not limited in this application.

[0050] As a preferred solution, there are multiple branch pipelines 122, each of which is connected to the main pipeline 121. In this case, multiple branch pipelines 122 may be connected or disconnected. In one example, each branch pipeline 122 may only be connected to the main pipeline 121, and any two branch pipelines 122 are disconnected.

[0051] As another preferred solution, there are multiple branch pipelines 122 , and the multiple branch pipelines 122 are connected in sequence, and the main pipeline 121 is connected to at least one branch pipeline 122 .

[0052] Reference Figure 1 As shown, in one embodiment, the number of branch pipes 122 is 3, the three branch pipes 122 are connected in sequence to form a U-shaped structure, and the three branch pipes 122 surround the hatch 21. At this time, the hatch 21 is set in the groove formed by the branch pipes 122 of the U-shaped structure.

[0053] It should be noted that the above-mentioned U-shaped structure refers to a structure in which three branch pipelines 122 are connected in sequence, and adjacent branch pipelines 122 are perpendicular to each other. Among them, the adjacent branch pipelines 122 are perpendicular to each other means that the angle between adjacent branch pipelines 122 is approximately 90°.

[0054] Preferably, the three branch pipes 122 are enclosed and fixed at positions adjacent to the edge of the hatch 21, that is, the three branch pipes 122 are arranged adjacent to the hatch 21 and surround the hatch 21. In one example, the hatch 21 is rectangular, and the three branch pipes 122 can be arranged adjacent to the three edges of the hatch 21 to enhance the dust suction effect of the dust removal mechanism 1 on the dust near the hatch 21.

[0055] In other embodiments, the number of branch pipes 122 may be 2, 4 or more. When the number of branch pipes 122 is 2, the branch pipes 122 may form an L-shaped structure, and the L-shaped branch pipes 122 may be arranged adjacent to two edges of the cabin door 21. When the number of branch pipes 122 is 4, the branch pipes 122 may form a U-shaped structure, and the U-shaped branch pipes 122 may be arranged adjacent to all edges (i.e., four edges) of the cabin door 21, and the cabin door 21 is completely surrounded by the branch pipes 122.

[0056] In a preferred embodiment, there are multiple doors 21 and air guide channels 12, each air guide channel 12 is matched with a corresponding door 21, and all air guide channels 12 are connected to the negative pressure fan 13. In this way, all doors 21 are matched with corresponding air suction ports 11 and air guide channels 12, and when the negative pressure fan 13 is turned on, it can synchronously drive all air suction ports 11 to inhale dust near the corresponding door 21, so as to improve the dust removal effect of the dust removal mechanism 1 when the door 21 is opened.

[0057] Continue to refer to Figure 1 In this embodiment, the number of doors 21 and air guide channels 12 is 3, and the doors 21 include a front door and two side doors. The air guide channel 12 that matches the front door is defined as the first air guide channel, and the air guide channel 12 that matches the side door is defined as the second air guide channel. As shown in the figure, the first air guide channel includes a U-shaped branch pipeline 122, and the branch pipeline 122 of the first air guide channel is fixed near the front door to absorb dust overflowing from the front door. The second air guide channel includes a main pipeline 121 and a U-shaped branch pipeline 122, and the branch pipeline 122 of the second air guide channel is fixed near the side door to absorb dust overflowing from the side door. The branch pipeline 122 of the first air guide channel is respectively connected to the main pipelines 121 of the two second air guide channels, and at this time, the dust sucked by the branch pipeline 122 of the first air guide channel is respectively introduced into the main pipelines 121 of the two second air guide channels. In this way, the structure of the dust removal mechanism 1 can be simplified while ensuring the dust removal effect of the dust removal mechanism 1, so as to save the investment and maintenance costs of the processing equipment.

[0058] More preferably, the dust removal mechanism 1 further includes a collection box 15, which is connected to all the air guide channels 12 and the negative pressure fan 13, that is, all the air guide channels 12 are connected to the negative pressure fan 13 through the collection box 15. The collection box 15 is used to introduce the material in the air guide channel 12 into the exhaust pipe 14 under the action of the negative pressure fan 13. Specifically, the collection box 15 is used to collect all the dust passing through the air guide channel 12 so as to stabilize the air pressure of the dust. The collection box 15 is also used to introduce all the dust into the exhaust pipe 14 under the action of the negative pressure fan 13.

[0059] In summary, the utility model provides a dust removal mechanism 1 and processing equipment. Since the air inlet 11 of the dust removal mechanism 1 is arranged near the hatch 21 of the equipment body 2, the dust removal mechanism 1 can form a negative pressure environment near the hatch 21 after it is opened. At this time, the dust overflowing from the cabin of the equipment body 2 is sucked into the dust removal mechanism 1 together with the surrounding air, and a large amount of air near the equipment body 2 is supplemented to the position of the hatch 21, making it difficult for the powder in the cabin to overflow, and the dust reduction effect is obvious, which effectively maintains the operating environment of the workshop. At the same time, the setting of the dust removal mechanism 1 can also prevent the operator from directly contacting a large amount of dust when opening the hatch 21, thereby reducing or even avoiding the harm of dust to the operator's body.

[0060] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation to the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the protection scope of the utility model.
