Description

Technical Field

[0001] The present application relates to the technical field of dust removal equipment, and in particular to a feeding port dust collecting device and a mixing device. Background Art

[0002] In powder production, some materials with poor fluidity or trace additions that cannot be fed using automatic feeding equipment often need to be fed manually through the feeding port. When feeding, the pressure generated by the material entering the mixing equipment (reactor or mixing tank, etc.) will cause the gas inside the container to be discharged outward, driving the material dust to escape from the feeding port. The escaping material dust floats in the air, which will not only pollute the workshop environment, but also accelerate the wear of the equipment when it floats on the equipment. Moreover, the dust will enter the human body through the respiratory tract, skin and other organs. Long-term exposure to this environment will cause lesions in the workers' respiratory and immune systems, damaging human health. Utility Model Content

[0027] In order to facilitate the understanding of the present application, the present application will be described more comprehensively with reference to the relevant drawings below. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many other different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0029] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0030] In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically defined. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0031] As described in the background technology, when manual feeding is carried out, the pressure generated by the material entering the mixing equipment (reactor or mixing tank, etc.) will cause the gas inside the container to be discharged outward, driving the material dust to escape from the feeding port. The escaping material dust floats in the air, which will not only pollute the workshop environment, but also accelerate the wear of the equipment when it floats on the equipment. Moreover, the dust will enter the human body through the respiratory tract, skin and other organs. Long-term exposure to this environment will cause lesions in the workers' respiratory and immune systems, damaging human health.

[0032] In order to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a dust collecting device for a feeding port, such as Figure 1 As shown, the feeding port dust collecting device comprises a dust collecting hood 10, a bag dust collector 20, an exhaust fan 30 installed on the clean air outlet of the bag dust collector 20, and a dust collecting pipeline 40 connected between the dust collecting hood 10 and the dust gas inlet of the bag dust collector 20. The dust collecting hood 10 is conical, and the dust collecting hood 10 is used to be arranged above the feeding port 1 with the large end facing downward, and the small end of the dust collecting hood 10 is connected to the end of the dust collecting pipeline 40 away from the bag dust collector 20. The dust collecting pipeline 40 comprises a fixed pipe 41, a movable pipe 42, and a rotating pipe joint 43 that rotatably connects the fixed pipe 41 and the movable pipe 42, the end of the fixed pipe 41 away from the movable pipe 42 is connected to the dust gas inlet of the bag dust collector 20, the end of the movable pipe 42 away from the fixed pipe 41 is connected to the small end of the dust collecting hood 10, and the movable pipe 42 can rotate relative to the fixed pipe 41, so that the dust collecting hood 10 is arranged above the feeding port 1 or moved away from the feeding port 1.

[0033] The working principle of the dust collecting device at the feeding port is as follows: when manual feeding is carried out, the dust collecting hood 10 is turned to the top of the feeding port 1, and the exhaust fan 30 is turned on. A negative pressure is formed inside the bag dust collector 20, the dust collecting pipeline 40 and the dust collecting hood 10 under the action of the exhaust fan 30. When manual feeding is carried out, the dust escaping from the feeding port 1 is collected by the dust collecting hood 10 above, and enters the bag dust collector 20 through the dust collecting pipeline 40. The bag dust collector 20 only needs to be cleaned regularly.

[0034] It is understandable that the cross-sectional area of ​​the large end of the dust collecting hood 10 needs to be designed to be slightly larger than the cross-sectional area of ​​the feeding port 1 so that the dust collecting hood 10 can completely cover the feeding port 1 .

[0035] In the embodiment of the present application, the dust collecting pipeline 40 connected between the dust collecting hood 10 and the dust gas inlet of the bag dust collector 20 in the feeding port dust collecting device includes a fixed pipe 41 and a movable pipe 42 that are rotatably connected. The movable pipe 42 can rotate relative to the fixed pipe 41 so that the dust collecting hood 10 is set above the feeding port 1 or moved away from the feeding port 1. According to this design, when it is necessary to open or close the sealing cover (not shown in the figure) on the feeding port 1, the dust collecting hood 10 is moved away from the feeding port 1 so that the dust collecting hood 10 does not hinder the opening and closing operation of the sealing cover; before manual feeding, the dust collecting hood 10 is turned to the top of the feeding port 1. Since the dust collecting hood 10 can be rotated and adjusted, the height between the dust collecting hood 10 and the feeding port 1 can be designed to be smaller, thereby improving the dust collection capacity during manual feeding. The use of the feeding port dust collecting device can effectively remove the dust generated at the feeding port 1 during manual feeding, reducing the damage of dust to the human body and equipment.

[0036] In one embodiment, if Figure 1 As shown, at least one-half of the edge of the large end of the dust collecting cover 10 is provided with a protective curtain 50 extending downward, and the protective curtain 50 is arranged to form a semi-enclosed structure.

[0037] The protective curtain 50 is used to shield the vicinity of the feeding port 1 to prevent dust from escaping from between the feeding port 1 and the dust collecting hood 10 when feeding is done manually, so that all the dust escaping from the feeding port 1 is collected by the dust collecting hood 10, thereby improving the dust collection capacity.

[0038] In addition, when the dust collecting hood 10 is not in use, the protective curtain 50 can be pulled up to cover the dust collecting port of the dust collecting hood 10 to protect the dust collecting port.

[0039] Specifically, the protective curtain 50 may be a cloth curtain.

[0040] In one embodiment, if Figure 2 As shown, the dust collecting hood 10 is a double-layer structure, including a conical outer cover body 11 and a conical inner cover body 12 arranged on the inner side of the conical outer cover body 11 and spaced apart from the conical outer cover body 11. The small ends of the conical outer cover body 11 and the conical inner cover body 12 are both provided with openings, and the opening of the small end of the conical outer cover body 11 is connected to one end of the movable pipe 42 away from the fixed pipe 41, and a dust suction port for dust to enter is formed between the large end of the conical outer cover body 11 and the large end of the conical inner cover body 12.

[0041] It can be understood that since only a small amount of dust escapes from the feeding port when feeding, by setting the dust collecting hood 10 as above, it can form a vacuum wind curtain around the feeding port to block the dispersion of dust. Compared with the design of a wide-mouth single-layer structure, there is no problem of poor dust collection effect far away from the dust collecting port due to excessively large cross-section.

[0042] In a specific embodiment, Figure 2 As shown, the opening aperture of the small end of the conical outer cover 11 is larger than the opening aperture of the small end of the conical inner cover 12. With this design, the dust not sucked in by the dust suction port can be sucked into the movable pipe 42 through the opening of the small end of the conical inner cover 12, thereby entering the bag dust collector 20.

[0043] In a specific embodiment, Figure 2 As shown, the gap between the conical outer cover 11 and the conical inner cover 12 is 1 cm-2 cm. It can be understood that too small or too large a gap will reduce the dust collection capacity of the dust suction port.

[0044] In one embodiment, if Figure 1 As shown, a switch valve 60 is provided between the small end of the dust collecting cover 10 and the movable pipe 42. Specifically, the switch valve 60 can be a manual valve.

[0045] In a specific embodiment, the dust gas inlet of the bag dust collector 20 is connected to the fixed pipes 41 of multiple dust collecting pipelines 40 through a main pipeline, and the dust hoods 10 respectively arranged on the movable pipes 42 of the multiple dust collecting pipelines 40 can be respectively arranged on different mixing equipment in the same workshop. When manually feeding some mixing equipment, the passage between the dust hood 10 and the movable pipe 42 on the corresponding mixing equipment is opened by the switch valve 60, and the other switch valves 60 are closed. With this design, multiple dust collecting pipelines 40 share one bag dust collector 20, saving equipment costs.

[0046] In some specific embodiments, Figure 1 As shown, the fixed pipe 41 and the movable pipe 42 are both formed by connecting multiple sections of pipes via quick-release joints. This design facilitates the disassembly, maintenance and replacement of the equipment and pipes.

[0047] According to another aspect of the present application, the embodiment of the present application also provides a mixing device, such as Figure 1 As shown, the mixing equipment includes the dust collecting device at the feeding port in the above embodiment.

[0048] Since the mixing equipment adopts the feeding port dust collecting device provided in the present application, it can effectively remove the dust generated at the feeding port during manual feeding, thereby reducing the damage of dust to human body and equipment.

[0049] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
