Description

Technical Field

[0001] This utility model relates to the field of sewage sedimentation treatment technology, specifically a foam removal device for sedimentation tanks. Background Technology

[0002] Before wastewater treatment, in order to remove sand and other larger suspended solids from the wastewater, reduce the burden on subsequent treatment processes, and protect pumps, pipes and other equipment from wear and blockage, sedimentation tanks are usually used to pre-treat the wastewater.

[0003] When using existing sedimentation tanks, wastewater is usually controlled to flow into the sedimentation tank, and then the stirring blades are driven by a motor to accelerate the sedimentation process of sand particles, so that the sand particles in the wastewater can be better separated from the water. Under the influence of gravity, the sand particles gradually sink to the bottom of the tank.

[0004] Existing sedimentation tanks have the following problems: after sewage enters the sedimentation tank, air is easily mixed into the water and forms bubbles under the action of water flow and other actions. The presence of foam will interfere with the normal solid-liquid separation in the tank and will also carry some fine solid particles, making them difficult to settle. To address this, we propose a foam removal device for sedimentation tanks. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a foam removal device for sedimentation tanks. The device breaks up the generated foam through a cleaning mechanism, causing the foam to rupture and reintegrate into the sewage, thus avoiding the presence of foam from interfering with the normal solid-liquid separation in the tank. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foam removal device for a sedimentation tank, comprising a tank body and a cleaning mechanism;

[0007] The cleaning mechanism includes a rotating rod, a connecting rod, a cleaning chamber, a rotating rod, gears, an internal gear ring, and a crushing rod. A rotating rod is rotatably connected to the middle of the top wall of the tank. Connecting rods are evenly distributed on the upper outer surface of the rotating rod. A cleaning chamber is located at the end of each connecting rod away from the rotating rod. A rotating rod is rotatably connected inside each cleaning chamber. Gears are fixedly fitted through the top wall of each rotating rod, passing through the cleaning chamber. An internal gear ring is located on the top wall of the tank. Four gears mesh with one internal gear ring. Crushing rods are evenly distributed on the lower outer surface of each rotating rod, all located inside the cleaning chamber. The cleaning mechanism breaks up the generated foam, causing it to rupture and reintegrate into the wastewater, thus preventing the foam from interfering with the normal solid-liquid separation process within the tank.

[0008] Furthermore, it also includes a microcontroller, which is located outside the tank and its input terminal is electrically connected to an external power supply to facilitate the normal operation of the control device.

[0009] Furthermore, a motor is provided on the upper surface of the tank. The lower end of the motor's output shaft is fixedly connected to the upper end of the rotating rod, and the input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0010] Furthermore, the cleaning mechanism also includes sliding protrusions and annular grooves. The upper end of the rotating rod is provided with sliding protrusions, and the top wall of the tank is provided with annular grooves. The sliding protrusions are all slidably connected to the inside of the annular grooves to facilitate sliding and limiting.

[0011] Furthermore, the cleaning mechanism also includes a guide plate and a drain hole. The inlet of the cleaning chamber is provided with a guide plate, which is inclined. The side wall of the cleaning chamber away from the inlet is provided with evenly distributed drain holes to facilitate the entry and discharge of foam.

[0012] Furthermore, the outer surface of the rotating rod is fixedly fitted with a fixing seat on both the upper and lower sides, and the outer surface of the fixing seat is provided with uniformly distributed stirring blades, which facilitates the acceleration of the sand settling process.

[0013] Furthermore, a feed pipe is provided at the feed inlet on the upper side of the outer surface of the tank. A portion of the feed pipe inside the tank is swirling, which facilitates the swirling motion of the sewage and accelerates the efficiency of the sedimentation process.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This sedimentation tank foam removal device has the following advantages:

[0015] When foam is generated, the rotation of the rotating rod drives the cleaning chamber to rotate via the connecting rod, causing the rotating rod to rotate around the rotating rod as the center. The foam is scraped into the cleaning chamber through the guide plate. At the same time as the rotating rod rotates around the rotating rod as the center, the internal gear ring drives the rotating rod to rotate via the gear. The breaking rod breaks the foam that enters the cleaning chamber, causing the foam to break and re-integrate into the sewage. Then the sewage is discharged from the cleaning chamber through the drain hole, avoiding the presence of foam from interfering with the normal solid-liquid separation in the tank, thereby improving the efficiency of the sedimentation process.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This embodiment provides a technical solution: a foam removal device for a sedimentation tank, including a tank body 1 and a cleaning mechanism 3, and also a microcontroller 2. The microcontroller 2 is disposed outside the tank body 1, and the input end of the microcontroller 2 is electrically connected to an external power source. The outer surface of the rotating rod 301 is fixedly fitted with a fixing seat 5 on both the upper and lower sides. The outer surface of the fixing seat 5 is provided with uniformly distributed stirring blades 6. The feed inlet opened on the upper side of the outer surface of the tank body 1 is provided with a feed pipe 7. A part of the feed pipe 7 located inside the tank body 1 is in a swirling shape. The operator adds sewage into the tank body 1 through the feed pipe 7. Because the part of the feed pipe 7 located inside the tank body 1 is in a swirling shape, the sewage undergoes swirling motion, which speeds up the efficiency of sedimentation. The rotation of the rotating rod 301 drives the stirring blades 6 to rotate around the rotating rod 301 through the fixing seat 5, which speeds up the efficiency of sedimentation.

[0025] Cleaning mechanism 3 includes a rotating rod 301, a connecting rod 302, a cleaning chamber 303, a rotating rod 304, a gear 305, an internal gear ring 306, and a crushing rod 307. The rotating rod 301 is rotatably connected to the middle of the top wall of the tank body 1. The upper end of the outer surface of the rotating rod 301 is provided with evenly distributed connecting rods 302. Each end of the connecting rod 302 away from the rotating rod 301 is provided with a cleaning chamber 303. Rotating rods 304 are rotatably connected inside each cleaning chamber 303. Gears 305 are fixedly sleeved on the upper end of the outer surface of each rotating rod 304, passing through the top wall of the cleaning chamber 303. The tank body... The top wall of tank 1 is provided with an internal gear ring 306, and four gears 305 are meshed with one internal gear ring 306. The lower end of the outer surface of the rotating rod 304 is provided with evenly distributed crushing rods 307, which are all located inside the cleaning chamber 303. The upper surface of tank 1 is provided with a motor 4, and the lower end of the output shaft of the motor 4 is fixedly connected to the upper end of the rotating rod 301. The input end of the motor 4 is electrically connected to the output end of the microcontroller 2. The cleaning mechanism 3 also includes a sliding protrusion 308 and a circular groove 309. The upper end of the rotating rod 304 is provided with a sliding protrusion 308, and the top wall of tank 1 is provided with a circular groove 309. The annular groove 309 and sliding protrusion 308 are slidably connected inside the annular groove 309. The cleaning mechanism 3 also includes a guide plate 310 and a drain hole 311. The inlet of the cleaning chamber 303 is provided with a guide plate 310, which is inclined. The side wall of the cleaning chamber 303 away from the inlet is provided with evenly distributed drain holes 311. Then, the operator operates the microcontroller 2 to turn on the motor 4. The output shaft of the motor 4 drives the rotating rod 301 to rotate. When foam is generated, the rotation of the rotating rod 301 drives the cleaning chamber 303 to rotate through the connecting rod 302. Rotating around the center of rotation 301 causes rotating rod 304 to also rotate around the center of rotation rod 301. The rotation of cleaning chamber 303 scrapes foam into cleaning chamber 303 through guide plate 310. At the same time, under the restriction of sliding protrusion 308 and annular groove 309, while rotating rod 304 rotates around the center of rotation rod 301, internal gear ring 306 drives rotating rod 304 to rotate through gear 305. The foam entering cleaning chamber 303 is broken by breaking rod 307, causing foam to break and re-integrate into sewage. Then sewage is discharged from cleaning chamber 303 through drain hole 311.

[0026] The working principle of the foam removal device for a sedimentation tank provided by this utility model is as follows: The operator adds wastewater into the tank 1 through the feed pipe 7. Because part of the feed pipe 7 inside the tank 1 is swirling, the wastewater undergoes swirling motion, accelerating the sedimentation process. Then, the operator controls the microcontroller 2 to turn on the motor 4. The output shaft of the motor 4 drives the rotating rod 301 to rotate. The rotation of the rotating rod 301 drives the stirring blades 6 to rotate around the rotating rod 301 via the fixed base 5, further accelerating the sedimentation process. When foam is generated, the rotation of the rotating rod 301 drives the cleaning chamber via the connecting rod 302. Rotating rod 303 rotates around rotating rod 301, causing rotating rod 304 to also rotate around rotating rod 301. The rotation of cleaning chamber 303 scrapes foam into cleaning chamber 303 through guide plate 310. At the same time, under the restriction of sliding protrusion 308 and annular groove 309, while rotating rod 304 rotates around rotating rod 301, internal gear ring 306 drives rotating rod 304 to rotate through gear 305. The foam entering cleaning chamber 303 is broken by breaking rod 307, causing the foam to break and re-integrate into sewage. Then the sewage is discharged from cleaning chamber 303 through drain hole 311.

[0027] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be a PY32MD310, the motor 4 can be an HSV-24-350, and the microcontroller 2 controls the operation of the motor 4 using methods commonly used in the prior art.
