Description

Technical Field

[0001] The utility model relates to the technical field of liquid level meter application, in particular to an anti-blocking structure of a liquid level meter. Background Art

[0002] Liquid level is an important indicator in the production process. During the process, the liquid level meter is expected to display accurately and timely. However, as the equipment ages, the sediment in the liquid will block the interface of the liquid level meter, which may cause distortion of the liquid level display. If the liquid level meter is blocked and cannot accurately display the liquid level, it will misjudge the working condition of the equipment and cause major production problems. For this reason, we designed a liquid level meter anti-blocking structure. Utility Model Content

[0003] In order to solve the technical problem that as the service life of equipment increases, the sediment in the liquid will block the interface of the liquid level meter, causing distortion of the liquid level display, the utility model provides a liquid level meter anti-blocking structure.

[0004] The utility model is implemented by the following technical scheme: a liquid level gauge anti-blocking structure, comprising a liquid level gauge joint, an anti-blocking ring is installed above the liquid level gauge joint, a connecting cavity is formed by the middle of the anti-blocking ring running through from top to bottom, a plurality of flow openings distributed in an annular shape are opened below the outer ring surface of the anti-blocking ring, and three top small holes in a circular array are opened at the top of the outer ring of the anti-blocking ring, and a top plate is installed at the top of the anti-blocking ring.

[0005] As a further improvement of the above scheme, a clamping groove is arranged between every two adjacent small holes on the top, and the three clamping grooves are annular and respectively located at the top of the anti-blocking ring, and the lower end surface of the top plate is integrally formed with three positioning blocks distributed in annular shapes, and the positioning blocks are clamped in the clamping grooves, which is convenient for clamping the positioning blocks into the clamping grooves, thereby facilitating the installation and disassembly of the top plate and the subsequent cleaning of the interior, and an interference fit is adopted between the positioning blocks and the clamping grooves.

[0006] As a further improvement of the above scheme, an inner stop cap is provided on the lower end surface of the top plate, the outer diameter of the inner stop cap is smaller than the inner diameter of the connecting cavity of the anti-blocking ring, and the inner diameter of the inner stop cap is larger than the outer diameter of the top of the liquid level gauge joint. The design of the inner stop cap can block the hole at the top of the liquid level gauge joint, so that impurities entering through the small hole on the top are not easy to fall into the hole at the top of the liquid level gauge joint, avoiding blockage thereof.

[0007] As a further improvement of the above scheme, the bottom end of the inner stop cap is below the top small hole, and the bottom end of the inner stop cap is above the top of the liquid level gauge connector. The debris that floats into the anti-blocking ring through the top small hole will be able to slide down along the outer surface of the inner stop cap, avoiding blockage of the top hole of the liquid level gauge connector.

[0008] As a further improvement of the above scheme, the top height of the flow port below the anti-blocking ring is not higher than the top height of the liquid level gauge joint, the sediment in the anti-blocking ring is not easy to enter the liquid level gauge port, and the liquid level gauge joint is placed 3-5cm above the bottom of the equipment, so large sediments inside the bottom of the equipment are not easy to cause blockage to the flow port.

[0009] As a further improvement of the above scheme, the flow port penetrates downward through the bottom end of the anti-blocking ring, and a baffle is welded to the lower half of the flow port, the bottom end of the baffle is flush with the bottom end of the anti-blocking ring, the top end of the baffle is cut away to form a flow slope, and the upper part of the outer ring surface of the liquid level gauge joint is also arranged into an inclined structure, which allows the sediment in the anti-blocking ring to slide to a certain extent, avoiding blockage caused by excessive accumulation of sediment.

[0010] As a further improvement of the above scheme, a mounting portion is formed by cutting away a portion above the outer ring surface of the liquid level gauge joint, and a spiral portion is provided at the inner bottom end of the anti-blocking ring. Matching thread lines are provided on the mounting portion and the spiral portion, and the two are screwed together through threads, which facilitates the installation and disassembly of the two, and further facilitates the subsequent replacement and cleaning.

[0011] As a further improvement of the above scheme, the outer diameter of the outer surface of the anti-blocking ring is not larger than the outer diameter of the liquid level gauge connector, and the outer diameter of the top plate is consistent with the outer diameter of the anti-blocking ring. A plug-in tube is usually provided on the equipment for installing the liquid level gauge. The liquid level gauge connector is usually directly plugged into the interior of the equipment through the plug-in tube and is threadedly connected to the plug-in tube. This allows the liquid level gauge connector and the anti-blocking ring and top plate above to be directly installed into the interior of the equipment without the need to install a corresponding structure inside the equipment. This also makes the overall assembly easy to remove and disassemble, facilitating subsequent cleaning and maintenance.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model provides an anti-blocking collar above the level gauge joint, and the anti-blocking collar is provided with a top small hole and a flow port, which can ensure that impurities inside the equipment will not directly fall to the top of the level gauge joint to cause blockage, and the top of the flow port is placed below the top of the level gauge joint, which makes it difficult for sediment inside the anti-blocking collar to enter the level gauge port, and the top small hole ensures that the upper part of the level gauge joint is full of liquid, and the level gauge display is more realistic;

[0014] 2. A flow slope is formed by cutting off part of the top of the baffle plate, and an inclined structure is also set above the outer ring surface of the level gauge joint, which allows the sediment in the anti-blocking ring to slide to a certain extent, avoiding blockage caused by excessive sediment accumulation;

[0015] 3. The anti-blocking ring and the top plate are directly installed above the level gauge joint, and their outer diameters are not larger than the outer diameter of the level gauge joint. This allows the level gauge joint and the anti-blocking ring and top plate above to be directly installed inside the equipment without the need to install the corresponding structure inside the equipment. This also makes the whole easy to remove and disassemble, facilitating subsequent cleaning and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1-Figure 4 A liquid level gauge anti-blocking structure of the present embodiment includes a liquid level gauge joint 1, an anti-blocking ring 2 is installed above the liquid level gauge joint 1, a connecting cavity is formed by the middle of the anti-blocking ring 2 running through the upper and lower parts, a plurality of flow openings 21 distributed in an annular shape are opened below the outer ring surface of the anti-blocking ring 2, and three top small holes 23 in a circular array are opened at the top of the outer ring of the anti-blocking ring 2, and a top plate 3 is installed at the top of the anti-blocking ring 2.

[0025] A snap-in groove 24 is provided between every two adjacent top small holes 23, and the three snap-in grooves 24 are annular and respectively located at the top of the anti-blocking ring 2, and three annular positioning blocks 31 are integrally formed on the lower end surface of the top plate 3, and the positioning blocks 31 are snap-fitted into the snap-in groove 24, which is convenient for snapping the positioning blocks 31 into the snap-in groove 24, thereby facilitating the installation and disassembly of the top plate 3 and the subsequent cleaning of the interior, and an interference fit is adopted between the positioning blocks 31 and the snap-in groove 24.

[0026] An inner stop cap 32 is provided on the lower end surface of the top plate 3. The outer diameter of the inner stop cap 32 is smaller than the inner diameter of the connecting cavity of the anti-blocking ring 2, and the inner diameter of the inner stop cap 32 is larger than the outer diameter of the top of the liquid level gauge connector 1. The design of the inner stop cap 32 can block the hole at the top of the liquid level gauge connector 1, so that impurities entering through the small hole 23 on the top are not easy to fall into the hole at the top of the liquid level gauge connector 1, thereby avoiding blockage thereof.

[0027] The bottom end of the inner stop cap 32 is below the top small hole 23, and the bottom end of the inner stop cap 32 is above the top of the liquid level gauge connector 1. The debris that floats into the anti-blocking ring 2 through the top small hole 23 will be able to slide down along the outer surface of the inner stop cap 32, avoiding blockage of the top hole of the liquid level gauge connector 1.

[0028] The top height of the flow port 21 below the anti-blocking ring 2 is not higher than the top height of the liquid level gauge connector 1, and the sediment in the anti-blocking ring 2 is not easy to enter the liquid level gauge port, and the liquid level gauge connector 1 is placed 3-5 cm above the bottom of the equipment, so large sediments inside the bottom of the equipment are not easy to cause blockage to the flow port 21.

[0029] The flow port 21 passes through the bottom end of the anti-blocking ring 2 downward, and a baffle plate 22 is welded to the lower half of the flow port 21. The bottom end of the baffle plate 22 is flush with the bottom end of the anti-blocking ring 2. During processing, the flow port 21 is directly passed through the entirety, which makes it easy to process. The baffle plate 22 is then welded inside the flow port 21 to block the threads on the mounting portion 11. A flow slope 221 is formed by cutting off the top end of the baffle plate 22. An inclined structure is also provided above the outer ring surface of the level gauge joint 1, which allows the sediment in the anti-blocking ring 2 to slide to a certain extent, thereby avoiding blockage caused by excessive sediment accumulation.

[0030] A mounting portion 11 is formed by cutting away a portion above the outer ring surface of the level gauge joint 1, and a spiral portion 25 is provided at the inner bottom end of the anti-blocking ring 2. Matching thread lines are provided on the mounting portion 11 and the spiral portion 25, and the two are screwed together to facilitate installation and disassembly of the two, and to facilitate subsequent replacement and cleaning.

[0031] The outer diameter of the outer surface of the anti-blocking ring 2 is not larger than the outer diameter of the liquid level gauge connector 1, and the outer diameter of the top plate 3 is consistent with the outer diameter of the anti-blocking ring 2. A plug-in tube is usually provided on the equipment for installing the liquid level gauge. The liquid level gauge connector 1 is usually directly plugged into the interior of the equipment through the plug-in tube and is threadedly connected to the plug-in tube. This allows the liquid level gauge connector 1 and the anti-blocking ring 2 and top plate 3 above to be directly installed into the interior of the equipment without the need to install corresponding structures inside the equipment. This also makes it easy to remove and disassemble the entire device, facilitating subsequent cleaning and maintenance.

[0032] The implementation principle of the anti-blocking structure of a level gauge in the embodiment of the present application is as follows: the top plate 3 is directly clamped into the three clamping grooves 24 at the top of the anti-blocking ring 2 through three positioning clamping blocks 31, and then the anti-blocking ring 2 is threadedly installed on the mounting portion 11 above the level gauge connector 1 through the spiral portion 25. When in use, the level gauge connector 1 can be directly plugged into the inside of the device and fixed. After the level gauge connector 1 is installed at the bottom end of the inside of the device, there is a certain height between the top of the level gauge connector 1 and the bottom end of the device. The liquid level gauge connector 1 has a blocking collar 2 sleeved on it, and the top of the flow port 21 on the blocking collar 2 is placed below the top of the liquid level gauge connector 1, which makes it difficult for the sediment inside the blocking collar 2 to enter the liquid level gauge port, and the top small hole 23 set on the top of the blocking collar 2 ensures that the top of the liquid level gauge connector 1 is full of liquid, and the liquid level gauge display is more realistic. The debris that floats into the inside of the blocking collar 2 through the top small hole 23 will be able to slide down along the outer surface of the inner stop cap 32, avoiding the blockage of the top hole of the liquid level gauge connector 1;

[0033] By arranging an anti-blocking collar 2 above the level gauge joint 1, and opening a top small hole 23 and a flow port 21 on the anti-blocking collar 2, it can be ensured that impurities inside the equipment will not directly fall to the top of the level gauge joint 1 to cause blockage, and the top of the flow port 21 is placed below the top of the level gauge joint 1, so that the sediment inside the anti-blocking collar 2 is not easy to enter the level gauge port, and the top small hole 23 ensures that the upper part of the level gauge joint 1 is full of liquid, and the level gauge display is more realistic;

[0034] By removing a portion of the top of the baffle plate 22 to form a flow slope 221, the upper portion of the outer ring surface of the level gauge joint 1 is also provided with an inclined structure, so that the sediment in the anti-blocking ring 2 can slide down to a certain extent, thereby avoiding blockage caused by excessive sediment accumulation;

[0035] The anti-blocking ferrule 2 and the top plate 3 are directly installed above the liquid level gauge joint 1, and their outer diameters are not larger than the outer diameter of the liquid level gauge joint 1. This allows the liquid level gauge joint 1 and the anti-blocking ferrule 2 and the top plate 3 above to be directly installed inside the equipment without the need to install a corresponding structure inside the equipment. This also makes the whole easy to remove and disassemble, facilitating subsequent cleaning and maintenance.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
