Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a wastewater treatment device for recycled concrete production. Background Art

[0002] During the production of recycled concrete, wastewater will be generated. The wastewater cannot be directly discharged and needs to be filtered. A wastewater treatment device for recycled concrete production is required.

[0003] In a wastewater treatment device for recycled concrete production with the authorization announcement number of "CN220939355U", the wastewater enters the filter box from the water inlet, and the preliminary filtration is achieved through the filter plate in the filter box and the solid-liquid separation of the wastewater is realized. The filter plate can be positioned and disassembled through the fixing component, which is convenient for the treatment of the sediment on the filter plate and the replacement of the filter plate. After the preliminary filtration, the wastewater enters the mixing box, and the pH value of the wastewater can be changed by the regulator input through the input pipe, ensuring that the treated wastewater meets the environmental protection requirements. The treated water exits from the water outlet and is further filtered through the filter component to obtain purer treated water. However, when the wastewater is filtered by the filter plate, the impurities inside the wastewater easily block the filter plate, and the operator needs to manually vibrate and knock the filter plate, which increases the workload of the operator and reduces the working efficiency of the device. When the pH value of the wastewater is changed by the regulator input through the input pipe, due to the lack of the stirring process of the filtered wastewater inside the box body, the mixing of the regulator and the wastewater is uneven, reducing the working quality of the device. Summary of the Invention

[0004] The utility model aims to solve the problems existing in the above prior art, and provides a wastewater treatment device for recycled concrete production, aiming to improve the working efficiency and working quality.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows: A wastewater treatment device for recycled concrete production includes a base and a box body. The upper end of the base is fixedly connected to the box body. An auxiliary stirring device is provided at the lower end of the base. An auxiliary knocking device is provided inside the box body. The left end of the box body is fixedly communicated with a feed inlet. The inner wall of the box body is fixedly connected with a filter plate by bolts. An upper cover is placed on the upper end of the box body, and a liquid inlet is fixedly communicated with the inner wall of the upper cover.

[0006] For further improvement, the auxiliary knocking device includes a first motor and a first housing. The first motor is fixedly connected to the box body through a bracket. The outer wall of the first housing is fixedly connected to the box body. The output shaft of the first motor is rotatably connected to the box body through a bearing. A rotating rod is fixedly connected to the output shaft of the first motor. A fixed rod is fixedly connected to the inner wall of the first housing. A spring is arranged on the outer wall of the fixed rod. Two ends of the spring are respectively fixedly connected to the collision block and the first housing.

[0007] For further improvement, the outer wall of the collision block is slidably connected to the first housing, and the inner wall of the collision block is slidably connected to the fixed rod.

[0008] For further improvement, a liquid outlet is fixedly communicated with the left side of the lower end of the base, and support legs are installed at the lower end of the base.

[0009] For further improvement, the auxiliary stirring device includes a second motor and a second housing. The upper end of the second housing is fixedly connected to the base. The second motor is fixedly connected to the second housing through a bracket. The output shaft of the second motor is rotatably connected to the second housing through a bearing. A first bevel gear is fixedly connected to the output shaft of the second motor. The first bevel gear meshes with a second bevel gear. A first gear is fixedly connected to the rotating shaft of the second bevel gear. The outer wall of the first gear is rotatably connected to a second gear. A second stirring blade is fixedly connected to the rotating shaft of the second gear.

[0010] For further improvement, the rotating shaft of the second bevel gear is respectively rotatably connected to the base and the second housing through bearings, and the rotating shaft of the second gear is rotatably connected to the base and the second housing through sealed bearings.

[0011] The beneficial effect of the present utility model is as follows: In the present utility model, through the cooperation of the auxiliary knocking device and the filter plate, when the output shaft of the first motor is started to rotate to drive the rotating rod to rotate, when the rotating rod contacts the collision block, the collision block is driven to move upward, and the spring is compressed by the collision block. When the rotating rod no longer contacts the collision block after rotating half a circle, the collision block is pushed to move downward rapidly under the reaction force of the spring, so that the end of the collision block impacts the surface of the filter plate. The output shaft of the first motor continuously rotates to drive the collision block to impact the surface of the filter plate, and the generated vibration avoids the blockage of the holes of the filter plate caused by impurities in the wastewater produced by the recycled concrete production. It is no longer necessary for the operator to manually knock the filter plate, reducing the workload of the operator and improving the work efficiency.

[0012] Through the cooperation of the auxiliary stirring device and the feeding port, the output shaft of the second motor is started to rotate, driving the first bevel gear to rotate. The first bevel gear rotates to drive the second bevel gear to rotate, and the second bevel gear rotates to drive the first stirring blade to rotate. The second bevel gear rotates to drive the first gear to rotate, the first gear rotates to drive the second gear to rotate, and the second gear rotates to drive the second stirring blade to rotate synchronously. The wastewater produced in the regeneration concrete production after adding the pH regulator inside the box body is stirred by the reverse rotation of the first stirring blade and the second stirring blade, making it more uniform, and making the wastewater and the pH regulator in the pH regeneration concrete production more evenly stirred, improving the working quality.

[0025] Working principle:

[0026] The operator connects the wastewater produced by recycled concrete to the liquid inlet 8 through a water pipe, so that the wastewater produced by recycled concrete enters the interior of the box 4 and is filtered through the filter plate 6. When there are many impurities accumulated on the surface of the filter plate 6, the upper cover 7 is opened, and the operator can disassemble and clean the filter plate 6 inside the box 4 by bolts.

[0027] Auxiliary tapping process for the filter plate:

[0028] The external power supply of the first motor 201 is turned on, and the output shaft of the first motor 201 is started to rotate to drive the rotating rod 203 to rotate. When the rotating rod 203 contacts the impact block 204, it drives the impact block 204 to move upward, and the impact block 204 compresses the spring 206. When the rotating rod 203 rotates half a circle and no longer contacts the impact block 204, the impact block 204 is pushed downward quickly under the reaction force of the spring 206, so that the end of the impact block 204 impacts the surface of the filter plate 6. The output shaft of the first motor 201 continuously rotates to drive the impact block 204 to impact the surface of the filter plate 6. The vibration generated by the impact prevents impurities in the wastewater of the recycled concrete production from causing the holes of the filter plate 6 to be blocked, and the auxiliary knocking process of the filter plate is completed, and the operator no longer needs to manually knock the filter plate 6.

[0029] Auxiliary mixing process for wastewater and pH regulator from recycled concrete production:

[0030] After the wastewater produced from recycled concrete is filtered, a pH regulator is added into the interior of the box body 4 through the feed inlet 5. The external power supply of the second motor 301 is connected, and the output shaft of the second motor 301 is started to rotate, driving the first bevel gear 303 to rotate. The rotation of the first bevel gear 303 drives the second bevel gear 304 to rotate. The rotation of the second bevel gear 304 drives the first stirring blade 308 to rotate. The rotation of the second bevel gear 304 drives the first gear 305 to rotate. The rotation of the first gear 305 drives the second gear 306 to rotate. The rotation of the second gear 306 drives the second stirring blade 307 to rotate synchronously. The wastewater produced from recycled concrete after adding the pH regulator into the interior of the box body 4 is stirred by the different-direction rotation of the first stirring blade 308 and the second stirring blade 307, so that the stirring is more uniform, and the auxiliary stirring process of the wastewater produced from recycled concrete and the pH regulator is completed, making the wastewater produced from recycled concrete and the pH regulator stirred more uniformly. After meeting the requirements, it can be discharged through the control of the liquid outlet pipe 9.
