Description

Technical Field

[0001] The present invention relates to the technical field of filter tank body detection, and in particular to a filter tank body sealing performance detection device. Background Art

[0002] A filter tank is usually a container used to filter impurities from liquids or gases. A sand tank, also known as a sand filter or sand filter tank, is a common filter tank used to remove suspended particles in water treatment. It usually consists of a pressure-resistant cylindrical container filled with quartz sand or other types of filter media. It is widely used in swimming pool water treatment and other fields. Before use, the sand tank must be sealed to avoid leakage during operation, which would affect the filtration effect and the overall performance of the system.

[0003] At present, the sealing performance test of sand cylinders usually uses compressed air to increase the pressure in the sand cylinder to a predetermined test pressure. After the pressure stabilizes, the pressure change in the sand cylinder is observed for a certain period of time. If there is a significant pressure drop, it indicates a leak. If a pressure drop is found, soapy water can be applied to the outside of the sand cylinder to find the place where bubbles emerge to determine the specific leak point. However, for sand cylinders with leaks, the efficiency of the test needs to be improved by manually applying soapy water to the parts to be tested one by one for observation and investigation. In addition, it is necessary to ensure that the soapy water is applied in place, otherwise it will affect the accuracy of the test. When testing sand cylinders with large volumes and high tops, it is inconvenient for personnel to observe and quickly determine the location of the leak.

[0004] Therefore, in order to improve the detection efficiency of the sand cylinder and improve the detection accuracy, the present invention provides a filter tank sealing performance detection device. Summary of the Invention

[0013] In the above-mentioned filter tank sealing performance detection equipment, the second sealing detection auxiliary mechanism includes an electric push rod, and the electric push rods are installed on the front bottom wall of the cross of the support frame, the two long vertical plates and the front side wall of the short vertical plate, and the output end of the electric push rod is fixedly connected to a cross piece, and the side wall of the cross piece is staggered with two spring rods and two round rods, and the ends of the two spring rods are jointly fixed with a second rubber sealing sleeve, and the ends of the round rod are jointly fixed with a second extrusion piece, and the second extrusion piece is sleeved on the second side wall of the rubber sealing sleeve.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Reference Figure 1 A filter tank sealing performance testing device includes a mobile base 1 and a sealing detection auxiliary mechanism 4. The mobile base 1 is provided with a clamping and stabilizing mechanism 2. The top wall of the mobile base 1 is fixedly connected to a support frame 3. The support frame 3 consists of two long vertical plates connected to the mobile base 1 symmetrically on the left and right, a cross fixedly connected to the top walls of the two long vertical plates, and a short vertical plate fixed to the rear bottom wall of the cross; a sealing detection auxiliary mechanism 4 for sealing the top of the sand cylinder is provided on the support frame 3, and a sealing detection auxiliary mechanism 2 5 for sealing the surrounding side of the sand cylinder is provided on the front bottom wall of the cross of the support frame 3, the two long vertical plates of the support frame 3, and the front side wall of the short vertical plate of the support frame 3; two soapy water spraying detection mechanisms 6 symmetrically on the left and right are provided on the mobile base 1, and a camera mechanism 7 is provided on the bottom wall of the cross of the support frame 3.

[0039] It is necessary to conduct sealing tests on the neck ring and exhaust valve installed on the top wall of the sand tank, the drain valve installed on the left wall of the sand tank, the water inlet and outlet installed from top to bottom on the right wall of the sand tank, the peephole installed on the upper part of the front side wall of the sand tank, and the inlet installed on the lower part of the rear side wall of the sand tank.

[0040] The mobile base 1 supports the whole, and is pushed from the back to the front to the sand cylinder to be tested. The base of the sand cylinder is clamped by the clamping stabilization mechanism 2, and the support frame 3 provides support for the sealing detection auxiliary mechanism 1 4, the sealing detection auxiliary mechanism 2 5 and the camera mechanism 7; first close each valve and inlet and outlet, and directly inflate the sand cylinder. By observing the pressure display, it is determined whether there is a leak. If there is no leakage, it means that all parts are well sealed, and the next sand cylinder to be tested can be directly replaced for testing.

[0041] If leakage occurs, the following group sealing test is carried out: the parts of the sand cylinder to be tested for sealing are divided into three groups, the top of the sand cylinder (neck ring and exhaust valve) is one group, the left side wall (drain valve) and the right side wall (water inlet and water outlet) are one group, and the front side wall and the rear side wall (peephole and inlet) are one group. The corresponding parts to be tested are sealed by the corresponding sealing detection auxiliary mechanism 1 4 and the sealing detection auxiliary mechanism 2 5.

[0042] During the inspection, the seal of one group of parts is released, and the pressure display number is observed to judge. If there is no air leakage, it means that the sealing of the unsealed parts of this group is good. If water leakage occurs, it means that the sealing of this group of parts is unqualified. In the above manner, multiple groups of parts are inspected one by one; then soapy water is sprayed by the soapy water spraying detection mechanism 6, and observed by the camera mechanism 7, so as to quickly and accurately find the leakage location.

[0043] Reference Figures 2 to 3 The clamping and stabilizing mechanism 2 includes a convex groove 21. A convex groove 21 is opened in the middle of the top wall of the movable base 1. Support seats 22 connected to the top wall of the movable base 1 by an electric slider are symmetrically arranged on the left and right sides of the convex groove 21. The outer walls of the two support seats 22 adjacent to each other are symmetrically fixed with clamping members 23. The clamping member 23 consists of a vertical plate connected to the support seat 22 and a semicircular plate fixed on one side wall of the vertical plate.

[0044] Push the mobile base 1 from the back to the front to the sand cylinder to be tested, and the base legs of the sand cylinder to be tested enter the corresponding convex grooves 21. The electric slider drives the two support bases 22 to move closer to each other. The two support bases 22 drive the clamping parts 23 to move, clamping the base legs of the sand cylinder to be tested from the left and right directions. The clamping of the base legs of the sand cylinder to be tested by the clamping parts 23 limits the movement of the mobile base 1, thereby ensuring the stability of the mobile base 1 during the subsequent testing process.

[0045] Reference Figure 4 The sealing detection auxiliary mechanism 4 includes a hydraulic rod 41. The hydraulic rod 41 is installed on the bottom wall of the middle part of the cross of the support frame 3. The bottom wall of the hydraulic rod 41 is connected to a cap-shaped extrusion piece 42 by a spring 1 for sliding up and down. The inner bottom wall of the extrusion piece 42 is connected to a rubber sealing sleeve 43 by a spring 2. A pressurizing component 44 is provided on the extrusion piece 42.

[0046] Reference Figures 4 and 5 The pressurizing assembly 44 includes an annular groove 441, an annular groove 441 is opened on the top wall of the extrusion member 42, and a rotating member 442 is slidably connected to the annular groove 441. The rotating member 442 is composed of a circular ring member connected to the annular groove 441, a plurality of round rods 1 fixed along the circumferential direction on the top wall of the circular ring member, a cross rod fixed to the top wall of the round rod 1, and a plurality of round rods 2 fixed along the circumferential direction on the bottom wall of the cross rod; the bottom wall of the round rod 2 of the rotating member 442 is rotatably connected with a sliding ball 443, the middle part of the cross rod of the rotating member 442 is threadedly connected to the side wall of the hydraulic rod 41, and the bottom wall of the sliding ball 443 fits into the top wall of the extrusion member 42.

[0047] Reference Figure 2 and Figure 6 The sealing detection auxiliary mechanism 2 5 includes an electric push rod 51. The electric push rod 51 is installed on the front bottom wall of the cross, the two long vertical plates and the front side wall of the short vertical plate of the support frame 3. The output end of the electric push rod 51 is fixedly connected to the cross piece 52. Two spring rods 53 and two round rods 54 are staggeredly fixed on the side wall of the cross piece 52. The ends of the two spring rods 53 are jointly fixed with a rubber sealing sleeve 2 55. The ends of the round rod 54 are jointly fixed with an extrusion piece 2 56. The extrusion piece 2 56 is sleeved on the side wall of the rubber sealing sleeve 2 55.

[0048] The bottom wall of the output end of the hydraulic rod 41 moves downward, driving the extrusion piece 42 and the rubber sealing sleeve 43 to move downward. The rubber sealing sleeve 43 moves down until it is close to the top wall of the sand cylinder. The rubber sealing sleeve 43 covers the neck ring and the exhaust valve on the top of the sand cylinder. The extrusion piece 42 continues to move downward with the push of the hydraulic rod 41. The spring 2 between the extrusion piece 42 and the rubber sealing sleeve 43 is compressed. The extrusion piece 42 applies pressure to the four sides of the rubber sealing sleeve 43, so that the bottom wall of the rubber sealing sleeve 43 and the top wall of the sand cylinder fit tightly. The hydraulic rod As the hydraulic rod 41 continues to move downward, the spring 1 between the hydraulic rod 41 and the extrusion piece 42 is compressed, and the side wall of the hydraulic rod 41 is threadedly connected to the middle part of the cross rod of the rotating member 442. As the hydraulic rod 41 moves downward, the rotating member 442 rotates on the annular groove 441 on the top wall of the extrusion piece 42, and the sliding ball 443 rotates and squeezes around the extrusion piece 42, applying pressure to the extrusion piece 42, so that the hydraulic rod 41 and the extrusion piece 42 are in close contact, further strengthening the sealing effect of the rubber sealing sleeve 43 on the top part of the sand cylinder.

[0049] Multiple sealing detection auxiliary mechanisms 25 correspond one-to-one to the drain valves, water inlets and outlets on the left and right walls of the sand cylinder, as well as the peepholes and inlets on the front and rear side walls. The output end of the electric push rod 51 moves toward the sand cylinder, driving the cross piece 52 and the rubber sealing sleeve 2 55 to move close to the corresponding part of the sand cylinder to be inspected. When the rubber sealing sleeve 2 55 is close to the side wall of the sand cylinder and covers the corresponding part of the sand cylinder to be inspected, the electric push rod 51 moves, the spring rod 53 shortens, and the round rod 54 pushes the extrusion piece 2 56 to continue moving close to the rubber sealing sleeve 2 55 and apply pressure around it, thereby strengthening the sealing effect of the rubber sealing sleeve 2 55 on the side parts of the sand cylinder.

[0050] When leakage occurs, a group sealing test is carried out. When the top neck ring and exhaust valve of the sand tank are tested for sealing, multiple sealing test auxiliary mechanisms 25 simultaneously seal the corresponding drain valves, water inlets and outlets on the left and right walls of the sand tank, as well as the sight glasses and inlets on the front and rear walls. Whether there is leakage is determined by observing the pressure display.

[0051] When the drain valve, water inlet and water outlet on the left and right walls of the sand tank are tested for sealing, the top neck ring and exhaust valve of the sand tank are sealed by the sealing test auxiliary mechanism 1 (4), and the sight glasses and inlets on the front and rear side walls are sealed by the sealing test auxiliary mechanism 2 (5). Whether there is any leakage is determined by observing the pressure display.

[0052] When the sight glasses and inlets on the front and rear side walls of the sand tank are being tested for tightness, the top neck ring and exhaust valve of the sand tank are sealed by the sealing detection auxiliary mechanism 1 (4). At the same time, the drain valve, water inlet and water outlet on the left and right walls are sealed by the sealing detection auxiliary mechanism 2 (5). Whether there is any air leakage is determined by observing the pressure display.

[0053] If a group has a leak, the sand cylinder parts in this group will be tested one by one, so that group testing can be carried out without manual inspection one by one, which speeds up the efficiency of testing.

[0054] Reference Figures 7 to 9The soapy water spray detection mechanism 6 includes an inverted U-shaped frame 61. The top wall of the mobile base 1 is symmetrically fixed with the inverted U-shaped frame 61. A spray assembly 62 is provided on the inverted U-shaped frame 61. The inverted U-shaped frame 61 includes a slide rail 1 621. The front and rear side walls of the inverted U-shaped frame 61 are both provided with a slide rail 1 621. The slide rail 1 621 is connected to an arc-shaped stable frame 1 622 for sliding up and down. The long vertical plate side wall of the support frame 3 is provided with a slide rail 2 623. The middle part of the arc-shaped stable frame 1 622 is connected to the slide rail 2 621 by an electric slider for sliding up and down. 23; an adjustment frame 624 is symmetrically arranged on the front and rear side of the two arc-shaped stabilizing frames 622, and the adjustment frame 624 consists of a rod connected to the arc-shaped stabilizing frame 622 and a support member hinged to the side wall of the rod by a torsion spring (not shown in the figure); a soapy water spray head 625 is installed on the support member of the adjustment frame 624, and a direction adjustment member 63 adapted to the support member of the adjustment frame 624 is fixedly connected symmetrically on the front and rear of the inverted U-shaped frame 61, and a wavy protrusion is provided on the side wall of the direction adjustment member 63 close to the adjusting frame 624.

[0055] The inverted U-shaped frame 61 supports the spray assembly 62, and the arc-shaped stable frame 1 622 is driven up and down by the electric slider, driving the soapy water spray head 625 to move up and down, and spraying soapy water around the sand tank through the soapy water spray head 625. By observing the position of the soapy water bubbles, the leakage position can be further accurately determined, which is convenient for subsequent repair and maintenance. In the process of the soapy water spray head 625 moving up and down, the adjustment frame 624 moves up and down on the wavy outer wall of the corresponding direction adjustment member 63. As the wavy protrusion adjustment frame 624 drives the soapy water spray head 625 to deflect around the slide rail 2 623, the torsion spring between the slide rail 2 623 and the adjustment frame 624 is adaptively expanded and contracted to achieve a more comprehensive spraying of soapy water around the sand tank by the soapy water spray head 625, and prevent the uneven spraying of soapy water from causing the inability to accurately locate the leakage position.

[0056] Reference Figures 10 to 12 The camera mechanism 7 includes a ring track 71, and the ring track 71 is fixedly connected to the bottom wall of the cross of the support frame 3. The bottom wall of the ring track 71 is slidably connected to the arc-shaped stabilizing frame 2 72 through an electric slider, and the bottom wall of the arc-shaped stabilizing frame 2 72 is installed with a camera 73.

[0057] The arc-shaped stabilizing frame 2 72 is driven by the electric slider to slide in the circumferential direction at the bottom of the circular track 71. The arc-shaped stabilizing frame 2 72 drives the camera 73 to move around the sand cylinder. The camera 73 performs a surrounding monitoring of the sand cylinder after the soapy water is sprayed, solving the problem that it is inconvenient to manually perform comprehensive monitoring of a large sand cylinder with a high top.

[0058] The specific operating steps of this filter tank sealing performance testing equipment are as follows:

[0059] First, the base of the sand cylinder is clamped by the clamping stabilizing mechanism 2. The clamping member 23 clamps the base support legs of the sand cylinder to be tested, limiting the movement of the mobile base 1 and ensuring the stability of the mobile base 1 during the subsequent testing process. First, close all valves and inlets and outlets, and directly inflate the sand cylinder. By observing the pressure display, it is determined whether there is a leak. If there is no leakage, it means that all parts are well sealed, and the next sand cylinder to be tested can be directly replaced for testing.

[0060] If leakage occurs, the following group sealing test is performed: the parts of the sand tank to be tested for sealing are divided into three groups: the top of the sand tank (neck ring and exhaust valve) is one group, the left and right walls (drain valve, water inlet and outlet) are one group, and the front and rear side walls (peephole and inlet) are one group. The rubber sealing sleeve 43 seals the neck ring and exhaust valve on the top of the sand tank, and multiple rubber sealing sleeves 55 seal the side parts of the sand tank. The multiple groups of parts are sealed by corresponding sealing mechanisms. The seal of one group of parts is released during inspection. If a group has leakage, the sand tank parts in this group are tested one by one.

[0061] Soapy water is sprayed around the sand tank through the soapy water spray head 625, and the leakage position is further accurately determined by observing the position of the soapy water bubbles. The camera 73 performs surrounding monitoring on the sand tank after the soapy water is sprayed.

[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
