Description

Technical Field

[0001] The utility model relates to the field of flow meters, in particular to a rotor flow meter with a filtering structure. Background Art

[0002] The rotor flowmeter is a common flow measurement instrument that determines the flow rate of the fluid by measuring the rotation speed of the rotating parts in the fluid. This type of flowmeter is usually used to measure the flow rate of liquid fluids and gas fluids.

[0003] In order to ensure stable use, the existing rotor flowmeters are provided with filtering structures at the ports at both ends of the flowmeter body. Such filtering structures can detect the filtration of impurities in the fluid during the entire use of the flowmeter. Therefore, in the process of fluid filtering, impurities may block the filter holes. The existing filtering structures use a quick-disassembly method to clear the blockage after the filter holes are disassembled. Such an operation method also requires the use of other equipment to clear the blockage of the filtering structure, and the filtering structure needs to be repeatedly disassembled and assembled, which makes the unblocking operation of the filtering structure not flexible enough.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-5 The rotor flowmeter with a filtering structure shown in the figure comprises a flowmeter body 1 , and an indicator 2 is arranged in the middle of the outer wall of the flowmeter body 1 .

[0027] Specifically, the outer walls at both ends of the flow meter body 1 are provided with connecting flanges 101 , and the middle parts of the connecting flanges 101 are surrounded by a plurality of connecting holes.

[0028] Specifically, an indicating area is provided on the top of the indicator 2 , and a pointer 201 for indicating the flow rate of the liquid passing through the flow meter body 1 is provided in the indicating area.

[0029] It should be noted that the rotor flowmeter uses the force exerted by the fluid on the rotating parts to measure the flow rate. When the fluid passes through the rotor flowmeter, the fluid exerts force on the rotating parts, causing the rotating parts to rotate. The rotation speed of the rotor is proportional to the fluid flow rate, so the fluid flow rate can be determined by measuring the rotation speed. In this solution, when the flowmeter body 1 performs flow measurement, the pointer 201 of the indicator 2 will detect and indicate the corresponding flow rate.

[0030] The ports at both ends of the flow meter body 1 are provided with filtering mechanisms, and the filtering mechanisms include:

[0031] A filter box 3, wherein a filter cavity 301 is provided inside the filter box 3;

[0032] It should be noted that in the setting of the present scheme, the radius of the filter box 3 is the same as the inner wall of the port of the flow meter body 1. At the same time, in the setting of the filter box 3, it can be fixed on the inner wall of the port of the flow meter body 1, and can also be set inside the flow meter body 1 in a nested manner. By opening the filter cavity 301, the two sides of the filter box 3 are separated into two baffle-like structures.

[0033] Specifically, a first filter hole 303 and a second filter hole 304 for liquid to pass through are respectively opened on both sides of the filter box 3 and penetrate the filter cavity 301.

[0034] It should be noted that, through the arrangement of the first filter hole 303 and the second filter hole 304, the baffle-like mechanisms on both sides of the filter box 3 are combined to form a filter screen structure. At the same time, in the arrangement of this scheme, the first filter hole 303 and the second filter hole 304 are of the same size and shape, and the two are arranged one by one in the horizontal direction, so that the fluid to be detected can smoothly pass through the flow meter body 1.

[0035] The brush cleaning member is rotatably inserted and connected in the filter cavity 301 , and is used for brushing and cleaning the filter box 3 .

[0036] Specifically, an operating annular groove 302 for cooperating with the rotation operation of the cleaning member is formed on one side of the filter box 3 away from the center of the flow meter body 1 , and the bottom of the operating annular groove 302 is interconnected with the filter cavity 301 .

[0037] Further, the cleaning part includes:

[0038] Support column 5, both ends of which are fixedly connected to the middle of the inner walls of both sides of the filter chamber 301;

[0039] The control lever 4 is rotatably inserted into the operating ring groove 302;

[0040] It should be noted that, due to the opening of the operating ring groove 302, one side of the filter box 3 is separated from the box body of the entire filter box 3, and the setting of the support column 5 allows the entire filter box 3 to remain a whole. At the same time, in the setting of this scheme, the diameter of the control rod 4 is the same as the spacing between the inner ring wall of the operating ring groove 302, so that the control rod 4 is connected to the operating ring groove 302 by surrounding the wall, and for the convenience of operation, one end of the control rod 4 needs to be exposed at the operating ring groove 302, so that the brush sweeping part can be operated through the exposed end.

[0041] The brush plate 6 has one end fixedly connected to the bottom of the control rotating rod 4 , and the other end of the brush plate 6 is rotatably sleeved on the middle part of the supporting column 5 .

[0042] Furthermore, bristles 7 for scraping are provided on both sides of the brush plate 6 .

[0043] It should be noted that the brush plate 6 serves as a structural member connecting the control rotating rod 4 and the support column 5. At the same time, the bristles 7 need to be made of soft materials, and the length of the bristles 7 needs to exceed the distance between the two sides of the brush plate 6 and the inner walls of the filter chamber 301 on both sides. In this way, when the bristles 7 pass through the first filter hole 303 and the second filter hole 304, they can pass through the first filter hole 303 and the second filter hole 304, and brush and clear the first filter hole 303 and the second filter hole 304.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
