Description

Technical Field

[0001] The utility model relates to the technical field of blower filtering, in particular to an integrated water seal blower air filter and a blower filtering system. Background Art

[0002] With the development of the energy and environmental protection industries, blowers are used more and more frequently as necessary equipment for processes such as roasting and drying, and the air filters used in conjunction with blowers also play an indispensable role.

[0003] The current mainstream blower air filter is composed of an air filter cartridge (or filter cloth) with high filtering accuracy. The air filter cartridge is made with high precision and the average filter pore size is 1μm, but it is also more prone to clogging. Therefore, a layer of coarse filter is generally added in front of the air filter cartridge. For example, Chinese patent CN212309159U discloses a blast furnace blower air filter frame coarse filter, including a closed frame, a frame buckle, a filter layer and a filter layer support rod. The method of use is to fix the filter layer in the closed frame, and fix the frame coarse filter on the air filter suction port through the frame buckle.

[0004] Although this method increases the filtration of large particles and reduces the probability of filter clogging compared to traditional blower filters, in principle, it is no different from traditional blower filters and still uses filter holes for filtration. This filtration method has the following disadvantages:

[0005] 1. In industrial production, the air intake is required to remain stable. Due to the use of filter holes for filtering, the dust on the filter cartridge or filter cloth will accumulate more and more, which will cause the air intake to become smaller and smaller over time, making the air intake unstable over time.

[0006] 2. If you want to ensure stable air intake, you usually need to increase the fan frequency, which will lead to higher power consumption.

[0007] 3. Since the blower cannot be shut down at will during production, and the filter cloth or filter cartridge is not easy to disassemble, it cannot be replaced at any time. In addition, each blower and filter is independent, and the filter cloth needs to be replaced separately, which is time-consuming and labor-intensive. Utility Model Content

[0008] In view of the deficiencies in the prior art, the purpose of the embodiments of the utility model is to provide an integrated water seal blower air filter to solve the problems of unstable air intake volume over time, inconvenient disassembly and increased power consumption of traditional filters.

[0009] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0010] An integrated water-seal blower air filter comprises: a filter cartridge, an air inlet pipe and an air outlet pipe; the filter cartridge is filled with filtered water, the air inlet pipe is installed on the filter cartridge, the air inlet of the air inlet pipe is connected to the atmosphere, and the air outlet of the air inlet pipe is located in the filter cartridge and below the liquid level of the filtered water; the air outlet pipe is installed on the filter cartridge, the air inlet of the air outlet pipe is located in the filter cartridge and above the liquid level of the filtered water, and the air outlet of the air outlet pipe is connected to the blower; a liquid level gauge for calibrating the air intake volume is provided on the cartridge wall of the filter cartridge.

[0011] Optionally, the liquid level meter is a bypass tube having an upper end and a lower end, both of which are connected to the inner cavity of the filter cartridge, and the liquid level of the filtered water is lower than the upper end of the bypass tube, and the liquid level of the filtered water is higher than the lower end of the bypass tube.

[0012] Optionally, the upper end of the bypass pipe is at the same height as the air inlet of the air outlet pipe in the vertical direction, and the lower end of the bypass pipe is at the same height as the air outlet of the air inlet pipe in the vertical direction.

[0013] Optionally, a water inlet is provided at the bottom of the filter cartridge wall, and a water outlet is provided at the bottom of the filter cartridge wall.

[0014] Optionally, a sewage outlet is provided at the bottom of the filter cartridge wall.

[0015] Optionally, an elbow is provided at the top of the air inlet pipe, and the air inlet of the air inlet pipe is arranged downward.

[0016] Optionally, the air outlet of the air outlet pipe is provided with an outlet flange, and the air outlet pipe is detachably connected to the blower via the outlet flange.

[0017] The embodiment of the utility model further provides a blower filter system, comprising the integrated water seal blower air filter as described above.

[0018] Optionally, a plurality of blower air filters are provided, and the plurality of blower air filters are connected in series in sequence through a circulation pipe, and a valve is provided on the circulation pipe between each blower air filter.

[0019] Optionally, a centrifugal pump is provided on the circulation pipeline, and the circulation pipeline also has a wastewater discharge pipe.

[0020] One or more technical solutions provided in the embodiments of the present utility model have at least the following technical effects or advantages:

[0021] 1. When the blower is working, the air enters the liquid in the filter cartridge through the air inlet pipe and then enters the blower through the air outlet pipe, thereby filtering and cleaning the blower air intake. Therefore, the problem of dust accumulation on the filter cloth in the traditional filtering method causing the air intake volume to decrease is avoided; and compared with replacing the filter cloth, the air filter can directly replace the filtered water, thereby reducing the power consumption of the blower, and will not affect the normal production of the blower. It is more convenient than replacing the filter cloth, saving time and effort. At the same time, the current air intake volume can be determined by observing the liquid level of the liquid level gauge, and the air intake volume can be calibrated without adding a sensor, saving costs.

[0022] 2. The blower air intake can be kept stable for a long time. During the operation of the blower, a stable air intake means that the pressure difference between the air pressure in the filter and the atmospheric pressure remains constant. The filter of the utility model can determine the current air intake by observing the liquid level of the liquid level gauge. Therefore, as long as the liquid level in the cylinder remains constant, the air intake will remain constant.

[0023] 3. Reduce the power consumption of the blower. In industry, as the dust on the filter cloth accumulates more and more, it is inconvenient to remove the filter cloth. In order to maintain the stability of the air intake, it is usually necessary to increase the blower frequency, resulting in increased power consumption. However, this filter structure can easily replace the filtered water, and can well maintain the stability of the air intake without frequently adjusting the blower frequency, thereby indirectly reducing the power consumption of the blower.

[0024] 4. By connecting multiple water seal blower air filters in series, the filtered water in all filters can be easily replaced at the same time. Compared with the traditional filter disassembly and cleaning of filter cloth one by one, it saves manpower, material resources and financial resources.

[0025] Additional advantages of the present invention will be given in the following description, and some will become apparent from the following description or will be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0036] As introduced in the background technology, most filters currently used in industry are cloth filters. As the dust on the cloth accumulates, the air intake volume will decrease over time. In industrial production, the blower cannot be shut down at will, making it difficult to replace the filter at any time. Moreover, the replacement operation is troublesome. If the air volume is to be stable, the blower frequency can only be increased, which in turn leads to increased power consumption. In order to solve the problems of unstable air intake over time, inconvenient disassembly, and increased power consumption of traditional filters, the utility model proposes an integrated water seal blower air filter, which can efficiently and conveniently handle dust in the blower intake, and at the same time can stabilize the blower intake volume for a long time and reduce the blower power consumption.

[0037] like Figure 1 , Figure 2 , Figure 3As shown, the integrated water seal blower 9 air filter includes: a filter cartridge 8, an air inlet pipe 1 and an air outlet pipe 2; the filter cartridge 8 is filled with filtered water, the air inlet pipe 1 is installed on the filter cartridge 8, the air inlet of the air inlet pipe 1 is connected to the atmosphere, and the air outlet of the air inlet pipe 1 is located in the filter cartridge 8 and is lower than the liquid level of the filtered water; the air outlet pipe 2 is installed on the filter cartridge 8, the air inlet of the air outlet pipe 2 is located in the filter cartridge 8 and is higher than the liquid level of the filtered water, and the air outlet of the air outlet pipe 2 is connected to the blower 9; a liquid level meter 3 for calibrating the air intake volume is provided on the wall of the filter cartridge 8.

[0038] The air outlet of the filter is connected to the blower 9, and a certain level of water is injected into the filter cartridge 8 as a cleaning agent. Figure 4 , Figure 5 As shown, the difference in liquid level of the filter in the non-working state and the working state is displayed. In the non-working state, the liquid level in the air inlet pipe 1 and the liquid level in the filter cartridge 8 are on the same horizontal plane, while in the fan working state, the liquid level in the air inlet pipe 1 is lower than the liquid level in the filter cartridge 8.

[0039] When the blower 9 is working, the air enters the liquid in the filter cartridge 8 through the air inlet pipe 1 and then enters the blower 9 through the air outlet pipe 2, thereby filtering and cleaning the air intake of the blower 9. Therefore, the problem of reduced air intake due to dust accumulation on the filter cloth in the traditional filtering method is avoided; and compared with replacing the filter cloth, the air filter can directly replace the filtered water, thereby reducing the power consumption of the blower 9, and will not affect the normal production of the blower 9, and it is more convenient than replacing the filter cloth, saving time and effort.

[0040] In addition, the traditional filtering method needs to add a sensor to detect the air intake of the blower 9 and then accurately control the power consumption of the blower 9. In the present application, in the non-working state, the liquid in the cylinder is at the zero level of the liquid level meter 3. As the blower 9 is started, the pressure above the liquid surface in the cylinder gradually decreases, and the height of the liquid level gradually rises. Therefore, a certain liquid level corresponds to a certain air intake, and then corresponds to a certain frequency of the blower 9. Then, by observing the height of the liquid level of the liquid level meter 3, the current air intake can be determined. The air intake can be calibrated without adding a sensor, saving costs; further, when the air intake remains stable, it can play a role in stabilizing the fan frequency.

[0041] like Figure 1As shown, the liquid level gauge 3 is a bypass pipe, and the bypass pipe has an upper end and a lower end, and the upper end and the lower end are both connected to the inner cavity of the filter cartridge 8, and the liquid level of the filtered water is lower than the upper end of the bypass pipe, and the liquid level of the filtered water is higher than the lower end of the bypass pipe. The upper end of the bypass pipe is at the same height as the air inlet of the outlet pipe 2 in the vertical direction, and the lower end of the bypass pipe is at the same height as the air outlet of the inlet pipe 1 in the vertical direction. By arranging the liquid level gauge 3 on the wall of the filter cartridge 8, the liquid level gauge 3 starts from the lower end of the inlet pipe 1 and ends at the lower end of the outlet pipe 2, and the liquid level is between the two, and the amount of air intake is judged by the height of the liquid level.

[0042] like Figure 1 As shown, the bottom of the filter cartridge 8 is provided with a water inlet 6, a water outlet 5, and a sewage outlet 4. When the water quality inside a single filter deteriorates and affects the filtering effect, it can be replaced through the water inlet 6 and the water outlet 5, or through the water inlet 6 and the sewage outlet 4.

[0043] like Figure 1 As shown, an elbow is provided at the top of the air inlet pipe 1, and the air inlet of the air inlet pipe 1 is arranged downward. The elbow at the upper end of the air inlet pipe 1 can prevent foreign matter outside the system from entering the filter. An outlet flange 7 is provided at the air outlet of the air outlet pipe 2, and the air outlet pipe 2 is detachably connected to the blower 9 through the outlet flange 7.

[0044] Based on the above integrated water seal blower 9 air filter, the utility model also proposes a blower 9 filtering system, such as Figure 6 As shown, it includes multiple blowers 9 air filters, which are connected in series through a circulation pipe 11. A valve is provided on the circulation pipe 11 between each blower 9 air filter. A centrifugal pump 10 is provided on the circulation pipe 11, and the circulation pipe 11 also has a wastewater discharge pipe 12.

[0045] The filters are connected to each other through flanges and a circulation pipe 11. A centrifugal pump 10 is placed in the circulation pipe 11. The circulation pipe 11 between the filters is provided with a valve. When the water quality inside a single filter deteriorates and affects the filtering effect, it can be emptied through the sewage outlet 4, or the water in the system can be circulated and supplemented through the water outlet 5 and the water inlet 6.

[0046] Multiple identical filters are connected in series, and each filter is connected to a corresponding blower 9. The circulating water flows through multiple filters from left to right in sequence. When the water in the cylinder needs to be replaced, it can be discharged from the respective sewage outlets 4 or from the main sewage pipe. The water body is circulated and replaced in the circulation pipe 11 through the centrifugal pump 10, and the wastewater can be discharged through the wastewater discharge pipe 12. The water quality in the filter cylinder can be easily updated through the water intake of the centrifugal pump 10 and the drainage of the sewage valve.

[0047] The filtration system connects all the blower 9 filters in series to achieve dust removal for the air intake of multiple blowers 9, changing the traditional method of removing and replacing the filter cloths of filters one by one. At the same time, the presence of a circulating pump can quickly update the water quality in the filter, which is more convenient and quicker than traditional filter cloth renovation.

[0048] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
