[0002] Sewage slurry is usually detected by a floating ball liquid level detection device. The device is mainly composed of a floating ball and a matching measurement component. The floating ball generally floats on the surface of the sewage slurry. During operation, the floating ball floats up and down accordingly with the rise and fall of the liquid surface, and the position change is transmitted to the liquid level meter measurement display component through the connecting rod transmission structure connected thereto, thereby directly displaying the liquid level height of the sewage slurry. This device has a relatively simple structure, is convenient to install, and has a low cost. It is widely used in many sewage pump stations, treatment tanks, and other places, and provides an effective reference for monitoring the liquid level of sewage slurry.

DETAILED DESCRIPTION

[0024] In order to better understand the technical content of the utility model, the following specific embodiments are provided, and the utility model is further explained in combination with the drawings.

[0025] Referring to Figures 1 to 4 The utility model provides a floating ball 20 device for sewage slurry measurement, including display head 1, display head 1 top is equipped with wire outlet screw 2, display head 1 bottom is equipped with connecting rod 3, and connecting rod 3 bottom is connected with mounting seat 4, and mounting seat 4 is tightly connected with fixed disc 5, and fixed disc 5 bottom surface is equipped with measuring conduit 6, and measuring conduit 6 periphery side is slidably connected with floating ball 20 and scraping assembly, and floating ball 20 bottom and scraping assembly top are interconnected.

[0026] It should be noted that display head 1, wire outlet screw 2, floating ball 20, measuring conduit 6 and fixed disc 5 are all existing equipment, wherein display head 1 is a shell and an indicator. By connecting fixed disc 5 is installed on the top of sewage slurry pool, and floating ball 20 floats on the liquid surface according to the liquid volume equal principle, when the liquid level of sewage slurry pool changes, floating ball 20 also moves up and down, due to the magnetic effect, the dry spring of measuring conduit 6 is attracted by the magnetism of floating ball 20, and the liquid level position change is converted into an electric signal, and the actual position of the liquid is displayed by display head 1 with numbers, so that the remote detection of the liquid level in the sewage slurry pool is achieved.

[0027] Specifically, the measuring pipe 6 is extended into the sewage slurry and fixed at a preset position by the fixing disc 5, and the display head 1 and the outlet screw 2 are exposed at the top of the sewage slurry pool for the staff to observe. When the measuring pipe 6 is in the sewage slurry, the float ball 20 and the scraping assembly sleeved on the circumference of the measuring pipe 6 are lifted up by the density buoyancy of the sewage slurry. When the liquid level of the sewage slurry drops, the float ball 20 and the scraping assembly drop, so that the scraping assembly scrapes the particles adhered to the circumference of the measuring pipe 6. When the liquid level of the sewage slurry rises, the float ball 20 can smoothly rise on the circumference of the measuring pipe 6, avoiding that the existing measuring rod is easily adhered by the particles in the sewage slurry on the circumference. When the particles are not cleaned for a long time, the lifting movement of the float ball 20 on the measuring rod is seriously affected.

[0028] In the embodiment, the fixing disc 5 is a flange disc, and the top surface of the flange disc is threadedly connected with the bottom of the mounting seat 4.

[0029] The display head 1 and the temperature of the measuring pipe 6 are installed at the top of the sewage slurry pool by the flange disc shell, so as to facilitate the detection of the lifting of the liquid level.

[0030] In the embodiment, the top and the bottom of the measuring pipe 6 are respectively provided with the first limiting block 7 and the second limiting block 8, and the float ball 20 and the scraping assembly are lifted and moved between the first limiting block 7 and the second limiting block 8.

[0031] When the float ball 20 lifts along with the liquid level, the sliding distance of the float ball 20 is limited by the first limiting block 7 and the second limiting block 8, so as to facilitate the float ball 20 to detect the lifting of the liquid level according to the position limited by the first limiting block 7 and the second limiting block 8, thereby avoiding that the float ball 20 is separated from the measuring pipe 6 or the top of the float ball 20 contacts the flange disc, so that the lifting change of the liquid level cannot be truly detected.

[0032] Preferably, the bottom end of the measuring pipe 6 is in a circular arc shape, so as to facilitate the measuring pipe 6 to be extended into the bottom of the sewage slurry pool.

[0033] In the embodiment, the float ball 20 and the scraping assembly are connected by the first rod 9. The float ball 20 drives the scraping assembly to lift and move on the circumference of the measuring pipe 6, so as to scrape the particles on the circumference of the measuring pipe 6.

[0034] In the embodiment, the scraping assembly comprises a lifting shell 10, the top of the lifting shell 10 is provided with an opening matched with the measuring pipe 6, the lifting shell 10 is provided with a support table 11 inside, and an elastic scraping part is arranged between the support table 11 and the inner top of the lifting shell 10, and the elastic scraping part surrounds the circumference of the measuring pipe 6.

[0035] When the float ball 20 is lowered, the first rod 9 is driven to drive the lifting shell 10 to slide along the side of the measuring conduit 6. The opening of the lifting shell 10 is provided with a rolling ball, so that the opening is directly spaced from the measuring conduit 6, and the rolling ball is slid to improve the sliding efficiency. At the same time, when the elastic scraping part is lowered, the end part scrapes the side of the measuring conduit 6, and the fine particles adhered to the side of the measuring conduit 6 are removed, so that the side of the measuring conduit 6 is processed into a smooth state, and the float ball 20 is smoothly slid when it is raised.

[0036] Specifically, the elastic scraping part includes mutually symmetrical sliding plates 12, the sliding plates 12 are fixed to the inner side wall of the lifting shell 10, the scraping rods 13 are slidably connected between the inner side walls of the sliding plates 12, one end of the scraping rod 13 is connected to the inner side wall of the lifting shell 10 through the spring 14, and the end part of the scraping rod 13 is used to scrape the particles on the side of the measuring conduit 6.

[0037] The scraping rod 13 is pushed out of the sliding plate 12 by the elongation of the spring 14, and the other end of the scraping rod 13 is in contact with the measuring conduit 6. When the float ball 20 is lowered along the measuring conduit 6, the scraping rod 13 on the side of the measuring conduit 6 is scraped. And through the spring 14, the scraping rod 13 and the measuring conduit 6 are in flexible contact, which reduces the friction, so that the float ball 20 is smoothly lowered, and the scraping rod 13 can scrape the particles.

[0038] In addition, the particles refer to the sticky soil in the sewage slurry. Since the sticky soil adheres to the side of the measuring conduit 6 for a long time, it is easy to cause strong adhesion, and therefore, the scraping rod 13 is needed to process it.

[0039] Preferably, the scraping rod 13 is provided with a scraping piece 15, and the scraping piece 15 is in contact with the side of the measuring conduit 6. The scraping piece 15 is made of flexible material such as polyurethane, which can closely adhere to the surface of the measuring rod for effective scraping, and will not cause excessive friction resistance to the measuring rod.

[0040] In the embodiment, the side wall of the support table 11 is provided with a second rod 16, the bottom of the second rod 16 is provided with a sliding ball 17, the side of the measuring conduit 6 is provided with a sliding sleeve 19, the side wall of the sliding sleeve 19 is provided with a rotating fan page 21, the top is provided with a limiting groove 18, and the sliding ball 17 is slidably connected in the limiting groove 18.

[0041] It should be noted that the lifting shell 10, the support table 11, the sliding sleeve 19 and the rotating fan 21 page are all made of polytetrafluoroethylene, which has strong corrosion resistance and is suitable for the embodiment.

[0042] Since the sliding sleeve and the rotating fan page 21 are both immersed in the slurry, when the sliding sleeve and the rotating fan page 21 are lowered, the rotating fan page 21 is driven to rotate by the buoyancy of the slurry, thereby driving the particles scraped by the scraping blade 15 to spread in the water, avoiding re-sticking to the circumference of the measuring conduit 6. While the rotating fan page 21 is rotating, the sliding sleeve is rotating, and the inner wall of the limiting groove 18 at the top of the sliding sleeve is smooth, so that the sliding sleeve can smoothly rotate under the bearing of the sliding ball 17.

[0043] Preferably, the rotating fan page 21 is provided with at least three pieces, for increasing the driving force, blowing away the particles scattered at the top, and avoiding the particles to re-stick to the circumference of the measuring conduit 6.

[0044] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
