Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to a modular multi-stage dry filter. Background Technology

[0002] Modular multi-stage dry filters are a type of air purification equipment with a modular design. They are mainly used for the pretreatment of industrial waste gas (especially waste gas containing particulate matter and organic pollutants generated by processes such as painting and spraying). Their core feature is that the purification efficiency is improved step by step through multi-stage filtration, which can stably and effectively ensure the safe and stable operation of the system.

[0003] In the installation and maintenance of modular multi-stage dry filters, traditional structures often have many drawbacks. Moving the equipment requires large tools such as cranes, which are difficult to handle manually. During assembly, the filter needs to be supported by the crane and then aligned manually before being lowered. If adjustments are needed after lowering, the filter must be lifted and adjusted again, which is quite troublesome. Therefore, a modular multi-stage dry filter is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a modular multi-stage dry filter, which aims to improve the problems of the traditional structure of modular multi-stage dry filters, which requires crane to transport equipment during installation, manual support and alignment of the filter during assembly, and the need to lift it up again for adjustment after it is put down, which is very inconvenient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular multi-stage dry filter, including a filter, a connector detachably installed on the right side of the filter, a connecting plate fixedly connected to the front of both the filter and the connector, a limit plate elastically connected to the left inner wall of the connecting plate via a connecting spring, a limit block fixedly connected to the right end of the connecting plate, a support plate fixedly connected to the front of the filter, a support foot rotatably connected to the inner wall of the support plate, the inner wall of the support plate being fixedly connected to the left inner wall of the support foot by bolts, and casters provided at the bottom of both the filter and the connector.

[0006] As a further description of the above technical solution:

[0007] The front of both the filter and its connector are fixedly connected to a handle.

[0008] As a further description of the above technical solution:

[0009] The bottom of the limiting plate is provided with an inclined surface, which faces to the left.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the limiting plate is slidably connected to the left inner wall of the connecting plate, and the bottom end of the limiting plate is inserted into the inner wall of the limiting block.

[0012] As a further description of the above technical solution:

[0013] A groove is formed on the left side of the connecting plate, and the right end of the limiting block matches the inner wall of the groove.

[0014] As a further description of the above technical solution:

[0015] A rubber ball is fixedly connected to the bottom of the support leg.

[0016] As a further description of the above technical solution:

[0017] Both the connector and the filter have detachable access doors at their rear ends. The connector has a pre-drilled hole for a differential pressure gauge at its rear end. Both the connector and the filter have air outlets at their top ends. Both the filter and the connector have grilles fixedly connected to their top ends.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, through the mutual cooperation between the filter, connector, connecting plate and handle and other structures, and the bottom universal wheel and front handle, the equipment can be moved directly by manpower. The detachable connection design of the filter and connector allows for the replacement of corresponding parts individually without the need for overall disassembly, which greatly reduces maintenance costs. The front connecting plate achieves quick pre-positioning between modules through the elastic insertion of the limiting plate and the limiting block, combined with the groove matching setting, which effectively avoids misalignment caused by horizontal pulling. Moreover, the positioning can be easily released manually by sliding the limiting plate, making the operation convenient and efficient.

[0020] 2. In this utility model, the modular multi-stage dry filter device is equipped with a differential pressure transmitter, which effectively avoids the problem that the differential pressure is too large when the filter bag is used for too long and will not trigger an alarm, thereby improving the processing efficiency, reducing the operating frequency of the fan, and reducing energy consumption.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3This utility model provides an embodiment of a modular multi-stage dry filter, including a filter 1. A connector 11 is detachably installed on the right side of the filter 1. The installation of the filter 1 and the connector 11 facilitates subsequent individual replacement of the corresponding parts. A connecting plate 8 is fixedly connected to the front of both the filter 1 and the connector 11. The connecting plate 8 can serve as a pre-positioning device. A limiting plate 12 is elastically connected to the left inner wall of the connecting plate 8 through a connecting spring 13. The elasticity of the connecting spring 13 enables the limiting plate 12 to have the functions of resetting and limiting. A limiting block 14 is fixedly connected to the right end of the connecting plate 8. The limiting plate 12 and the limiting block... With the cooperation of 14, rapid pre-positioning is achieved. A support plate 16 is fixedly connected to the front of the filter 1. Support feet 7 are rotatably connected to the inner wall of the support plate 16. Two sets of support plates 16 correspond to one set of support feet 7, allowing the support feet 7 to rotate downwards when needed to support the entire unit. The inner wall of the support plate 16 is fixedly connected to the left inner wall of the support foot 7 by bolts 15. The bolts 15 fix and limit the position of the opened support foot 7. Both the filter 1 and connector 11 are equipped with casters 10 at their bottoms. The casters 10 facilitate the movement and installation of the filter 1 and its connector 11, thus avoiding the need for a crane for lifting and installation.

[0031] Reference Figures 4-6 The filter 1 and its connector 11 are both fixedly connected to the front of a handle 9, which facilitates manual movement of the filter 1 and its connector 11. The bottom of the limiting plate 12 is provided with an inclined surface, which faces left and facilitates insertion and fixing. The outer wall of the limiting plate 12 is slidably connected to the left inner wall of the connecting plate 8. The through-hole design facilitates subsequent manual removal to release the pre-positioning. The bottom end of the limiting plate 12 is inserted into the inner wall of the limiting block 14. The insertion design prevents the filter 1 and its connector 11 from being pulled horizontally. A groove is opened on the left side of the connecting plate 8, and the right end of the limiting block 14 matches the inner wall of the groove. The matching design facilitates subsequent connection. The bottom of the support foot 7 is fixedly connected with a rubber ball, which increases the friction between the overall device and the ground, thereby improving stability.

[0032] Reference Figures 1-3 Both connector 11 and filter 1 have detachable maintenance doors 4 at their rear ends. The maintenance doors 4 facilitate manual maintenance. Both connector 11 and filter 11 have differential pressure gauge reserved holes 3 at their rear ends. Differential pressure transmitters can be installed in the differential pressure gauge reserved holes 3. The control system uses the values ​​of the differential pressure transmitters to provide early warnings and prompt for filter bag replacement. Both connector 11 and filter 1 have air outlets 2 at their top ends. Filter 1 has an air inlet on its right side. Both filter 1 and connector 11 have grids 6 fixedly connected to their top ends. The function of grids 6 is to support the filter media, separate the filtration area, and guide the airflow evenly, while blocking large particles of impurities to prevent filter media blockage.

[0033] Working principle: The filter 1 and connector 11 are detachably connected on the right side to achieve modular assembly, which facilitates the replacement of corresponding parts individually; the connecting plate 8 at the front of the two is elastically connected to the limiting plate 12 (bottom slope facing left) and the limiting block 14 through the connecting spring 13, and the matching setting of the groove on the left side of the connecting plate 8 and the limiting block 14 achieves quick pre-positioning and avoids horizontal pulling. The positioning can be released manually by moving the limiting plate 12 through and sliding it; the bottom universal wheel 10 and the front handle 9 make it easy to move and install manually without the need for a crane. The support foot 7 connected to the inner wall of the support plate 16 can rotate downward when needed and is fixed by bolts 15 to support the whole. The rubber ball at the bottom increases friction and improves stability.

[0034] The inspection door 4 at the rear of the filter 1 and connector 11 facilitates manual maintenance. The top grille 6 supports the filter media, separates the filtration area, guides the airflow evenly, and blocks large particles of impurities. The top air outlet 2 and the air inlet on the right side of the filter 1 form an airflow channel. The differential pressure gauge reserved hole 3 at the rear can be used to install a differential pressure transmitter, so that the control system can provide a numerical warning prompt to replace the filter bag, thereby achieving efficient operation and convenient maintenance of multi-stage dry filtration.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
