Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a flocculation mixing device for wastewater treatment. Background Technology

[0002] In the wastewater treatment process, flocculation is the core pretreatment unit. Its goal is to destabilize and aggregate fine suspended particles and colloids in the water that are difficult to settle by adding flocculants, forming larger flocs that are easy to separate. As the initial and key step in the flocculation process, its efficiency directly determines the floc utilization rate, floc formation speed and quality, and thus profoundly affects the separation effect, effluent quality, reagent consumption and operating costs of subsequent sedimentation or flotation units.

[0003] Flocculation can cause suspended particles in water or liquid to aggregate and grow larger, or form flocs. Flocculation can accelerate the sedimentation of particles, thereby achieving the purpose of solid-liquid separation.

[0004] Currently, flocculation mixing is divided into two parts. The first part requires pretreatment to filter out large impurities in the wastewater. Because there are many impurities in the wastewater, the filter screen is often clogged when filtering large impurities, so the mixing effect of flocculation is limited. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flocculation mixing device for sewage treatment to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a flocculation mixing device for sewage treatment, comprising a water treatment tank, a pretreatment mechanism fixedly connected to one side of the top of the water treatment tank, an inlet pipe fixedly connected to the side of the pretreatment mechanism away from the water treatment tank, a mixing mechanism movably connected inside the water treatment tank, and a drain pipe fixedly connected to the side of the water treatment tank away from the pretreatment mechanism; the pretreatment mechanism includes a receiving box for support, a filter plate fixedly connected to the middle of the inner side of the receiving box, lifting inclined plates fixedly connected to both sides of the filter plate, collection boxes fixedly connected to the sides of the lifting inclined plates away from the filter plate, a first fixing plate fixedly connected to the side of the water treatment tank, an output motor fixedly connected to the side of the first fixing plate away from the water treatment tank, a reciprocating screw fixedly connected to the side of the output motor near the first fixing plate, a moving block meshing with the side of the reciprocating screw, and a cleaning component fixedly connected to the side of the moving block, the bottom end of the cleaning component contacting the top end of the filter plate.

[0007] Furthermore, the raised inclined plate is an inclined surface, and the bottom end of the filter plate is horizontal with the inclined surface of the raised inclined plate. The water inlet pipe discharges sewage into the filter plate.

[0008] Furthermore, each side of the cleaning component is fixedly connected to a movable block. One of the movable blocks is internally threaded with a reciprocating screw, and the other movable block is internally movably connected with a limit rod.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model includes a filter plate, an output motor, a reciprocating screw, and a cleaning component. When sewage flows above the filter plate, it is filtered by the filter plate, leaving large impurities on the filter plate. At this time, the output motor starts and drives the reciprocating screw to rotate.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figure 1 This utility model provides a flocculation mixing device for sewage treatment, including a water treatment tank 1, a pretreatment mechanism 2 fixedly connected to one side of the top of the water treatment tank 1, an inlet pipe 3 fixedly connected to the side of the pretreatment mechanism 2 away from the water treatment tank 1, a mixing mechanism 4 movably connected inside the water treatment tank 1, and a drain pipe 5 fixedly connected to the side of the water treatment tank 1 away from the pretreatment mechanism 2.

[0024] In this embodiment, wastewater enters through the inlet pipe 3, undergoes pretreatment in the pretreatment unit 2, and is then mixed through the mixing unit 4. After thorough mixing, the wastewater is discharged through the drain pipe 5, ensuring flocculation effect and thereby improving the wastewater treatment effect.

[0025] Reference Figure 2 and Figure 3The pretreatment mechanism 2 includes a receiving box 201 for support. A filter plate 206 is fixedly connected to the center of the inner side of the receiving box 201. Lifting inclined plates 207 are fixedly connected to both sides of the filter plate 206. A collection box 208 is fixedly connected to the sides of the lifting inclined plates 207 away from the filter plate 206. A first fixing plate 202 is fixedly connected to the side of the water treatment tank 1. An output motor 203 is fixedly connected to the side of the first fixing plate 202 away from the water treatment tank 1. A reciprocating screw 204 is fixedly connected to the side of the output motor 203 near the first fixing plate 202. A moving block 209 meshes with the side of the reciprocating screw 204. A cleaning component 205 is fixedly connected to the side of the 09. The bottom end of the cleaning component 205 contacts the top end of the filter plate 206. The lifting inclined plate 207 is inclined, and the bottom end of the inclined plate 206 and the lifting inclined plate 207 are horizontal. The inlet pipe 3 discharges sewage into the filter plate 206. Movable blocks 209 are fixedly connected to both sides of the cleaning component 205. A reciprocating screw 204 is threaded inside one movable block 209, and a limit rod 210 is movably connected inside the other movable block 209. A second fixed plate 211 is fixedly connected to the side of the limit rod 210, and the second fixed plate 211 is fixedly connected to the receiving box 201.

[0026] In this embodiment, the output motor 203 starts and drives the reciprocating screw 204 to rotate. When the reciprocating screw 204 rotates, the moving block 209 drives the cleaning component 205 to move back and forth above the filter plate 206. During the reciprocating movement, the impurities on the filter plate 206 are pushed into the collection box 208 through the lifting inclined plate 207, automatically cleaning the filter plate 206. The lifting inclined plate 207 is inclined, so the water pushed away by the cleaning component 205 will flow back to the filter plate 206 through both sides of the cleaning component 205, instead of being pushed into the collection box 208, thus avoiding frequent water entering the collection box 208 and requiring frequent cleaning. The moving block 209 is internally connected to a limiting rod 210, which makes the moving block 209 move more smoothly.

[0027] Reference Figure 2 and Figure 4 The cleaning component 205 includes a movable box 2051 that moves synchronously with the movable block 209. A movable plate 2052 is movably connected inside the movable box 2051. A fixed rod 2055 is movably connected inside the movable plate 2052. Both ends of the fixed rod 2055 are fixedly connected to the inside of the movable box 2051. A cleaning plate 2053 is fixedly connected to the bottom end of the movable plate 2052. A cleaning head 2054 is fixedly connected to the bottom end of the cleaning plate 2053. The bottom end of the cleaning head 2054 contacts the top end of the filter plate 206. A spring 2056 is provided at the top end of the side of the fixed rod 2055.

[0028] In this embodiment, when the cleaning head 2054 passes the raised inclined plate 207, the cleaning head 2054 and the cleaning plate 2053 move upward. At this time, the moving plate 2052 moves upward and compresses the spring 2056, so that the cleaning head 2054 can move upward, which has the effect of avoiding obstruction.

[0029] Reference Figure 5 The mixing mechanism 4 includes a support plate 401 for support. A servo motor 402 is fixedly connected to the top of the support plate 401. A rotating shaft 403 is fixedly connected to the bottom of the servo motor 402. A blade group 404 is fixedly connected to the side of the rotating shaft 403. A waterproof shell 405 is fixedly connected to the top of the support plate 401. The servo motor 402 is located inside the waterproof shell 405, and the waterproof shell 405 seals the servo motor 402. There are three blade groups 404, which are equidistantly distributed in the water treatment tank 1.

[0030] In this embodiment, when the servo motor 402 starts, it drives the rotating shaft 403 to rotate. When the rotating shaft 403 rotates, it drives the three sets of blades 404 on its side to rotate. When the blades 404 rotate, they can fully mix the sewage in the water treatment tank 1. The waterproof housing 405 protects the servo motor 402 to prevent it from being damaged by water.

[0031] The working principle of this utility model is as follows: During flocculation treatment, wastewater flows through the inlet pipe 3 to the top of the filter plate 206. At this time, the wastewater will be filtered through the filter plate 206 to intercept large-sized impurities. When the filter plate 206 intercepts large-sized impurities, the output motor 203 starts and drives the reciprocating screw 204 to rotate. When the reciprocating screw 204 rotates, it drives the moving block 209 and the cleaning component 205 to move. When the cleaning component 205 moves, the cleaning head 2054 and the cleaning plate 2053 below it come into contact with the filter plate 206 and scrape away the impurities above the filter plate 206. When the impurities are scraped away, the cleaning head 2054 and the cleaning plate 2053 move upward when passing the raised inclined plate 207. At this time, the moving plate 2052 moves upward and compresses the spring 2056. The cleaning plate 2053 pushes the impurities into the collection box 208 for collection. The inclined surface of the raised inclined plate 207 is set to prevent water from entering the collection box 208.

[0032] After the impurities are pushed into the collection box 208 for collection, the cleaning head 2054 is reset, so it moves away from the lifting inclined plate 207. The compressed spring 2056 is reset and causes the cleaning head 2054 to move downward, maintaining contact with the filter plate 206. When the cleaning head 2054 moves in the opposite direction, it pushes large impurities into the collection box 208 on the other side for collection.

[0033] After filtering out large impurities, the wastewater enters the water treatment tank 1. At this time, the servo motor 402 starts and drives the rotating shaft 403 to rotate. When the rotating shaft 403 rotates, it drives the three sets of blades 404 on its side to rotate. When the blades 404 rotate, they can fully mix the wastewater in the water treatment tank 1. After being fully mixed, the wastewater is discharged from the drain pipe 5.

[0034] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
