Description

Technical Field

[0001] This utility model belongs to the field of industrial wastewater treatment, specifically relating to a flocculant dosing device for industrial wastewater treatment. Background Technology

[0002] Industrial production processes generate large amounts of industrial wastewater containing various pollutants. If discharged directly without effective treatment, it will cause serious harm to the aquatic environment, soil ecology, and even human health. Therefore, the purification and treatment of industrial wastewater has become an indispensable and crucial link in the sustainable development of industry. In industrial wastewater treatment processes, flocculation sedimentation is widely used to remove suspended particles, colloidal substances, and some dissolved pollutants from wastewater due to its simple operation, moderate cost, and significant treatment effect. The core of this method lies in adding flocculants to the wastewater, causing pollutant particles to aggregate into larger flocs, which are then separated into solid and liquid phases through sedimentation. The effect of flocculant addition directly affects the efficiency of flocculation and sedimentation, and the performance of the addition device is the key factor determining the effect of addition.

[0003] Traditional flocculant dosing devices typically employ a fixed structure, storing the flocculant in a single silo and adding it quantitatively via a screw conveyor or pumping system. For large reaction tanks, it is difficult to achieve uniform distribution of the flocculant in the wastewater, which can easily lead to excessively high local concentrations, resulting in waste, or insufficient local concentrations, affecting the treatment effect.

[0004] Therefore, we propose a flocculant dosing device for industrial wastewater treatment to solve the above problems. Utility Model Content

[0005] To address the problem that fixed dosing devices cover a limited area, resulting in uneven distribution of flocculant in the reaction tank and affecting the flocculation effect, this utility model provides a flocculant dosing device for industrial wastewater treatment.

[0006] The solution adopted by this utility model to solve its technical problem is: a flocculant dosing device for industrial wastewater treatment, including a screw conveyor, a frame unit, two guide rails and N sets of storage units, characterized in that: the two guide rails are installed in parallel on the top of the reaction tank; The frame unit includes a drive assembly, a connecting shaft, a rotating shaft, and two parallel main beams. The connecting shaft and the rotating shaft are rotatably mounted between the two main beams. Two grooved wheels are fitted on the connecting shaft and the rotating shaft respectively. The four grooved wheels are arranged in pairs on the two guide rails. Two crossbeams are welded and fixed to the top of the two main beams; The drive assembly is installed at the bottom of the front crossbeam and is connected to the rotating shaft for driving the rotating shaft to rotate. The screw conveyor is fixedly installed between the two crossbeams, and has multiple discharge holes at its bottom and N feed pipes at its top. The N storage units are respectively arranged above the N feed pipes. The discharge end of the storage unit is connected to the feed pipe, so that the flocculant stored in the storage unit enters the screw conveyor through the feed pipe.

[0007] Preferably, the drive component is a geared motor, with a base mounted on the top of the geared motor. The base is welded and fixed to the bottom of the front crossbeam, and the rotating shaft is installed in the output shaft hole of the geared motor.

[0008] Preferably, sprockets are respectively mounted on the connecting shaft and the rotating shaft, and the two sprockets are connected by chain drive.

[0009] Preferably, the storage unit includes a discharge valve and a silo for storing flocculants. The discharge valve is installed at the bottom outlet of the silo, and the discharge end of the discharge valve is connected to the top of the feed pipe.

[0010] Preferably, the bottom of the hopper is equipped with four support legs, which are respectively mounted on two crossbeams.

[0011] Preferably, the main beam is made of C-shaped steel, and the crossbeam is made of square or rectangular tubing.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a geared motor to drive the rotating shaft to rotate, causing the grooved wheel to move along the guide rail, which in turn drives the screw conveyor to move stably along the length of the reaction tank. Combined with multiple discharge holes at the bottom of the screw conveyor, the flocculant can be evenly added to the reaction tank from multiple points during the movement. This avoids the situation of excessively high or insufficient local concentration of the agent caused by fixed addition in traditional devices, greatly improving the uniformity of flocculant distribution in wastewater, thereby ensuring the stability and reliability of the flocculation and sedimentation effect and reducing agent waste.

[0013] 2. In this utility model, multiple silos are distributed along the screw conveyor, and each silo is only responsible for supplying the adjacent screw conveyor section, which shortens the flocculant conveying path, ensures that the flocculant is evenly distributed during the conveying process, avoids the problem of uneven conveying caused by a single feeding point, and enables the flocculant to achieve a wider and more uniform diffusion in the wastewater pool, thereby improving the flocculation reaction efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1-2 This utility model provides a technical solution for a flocculant dosing device for industrial wastewater treatment: Example 1: according to Figure 1 and Figure 2 As shown, it includes a screw conveyor 1, a frame unit, two guide rails 3, and N sets of storage units. The two guide rails 3 are installed in parallel on the top of the reaction tank.

[0018] The frame unit includes a drive assembly, a connecting shaft 28, a rotating shaft 25, and two parallel main beams 21. Bearing seats 23 are respectively fitted at both ends of the connecting shaft 28 and the rotating shaft 25. The four bearing seats 23 are installed in pairs on the two main beams 21. Under the action of the bearing seats 23, the connecting shaft 28 and the rotating shaft 25 can rotate stably. Two grooved wheels 26 are respectively fitted on the connecting shaft 28 and the rotating shaft 25. The four grooved wheels 26 are arranged in pairs on the two guide rails 3.

[0019] Two crossbeams 22 are welded and fixed to the top of the two main beams 21. The drive component is a geared motor 24. A base 29 is installed on the top of the geared motor 24. The base 29 is welded and fixed to the bottom of the front crossbeam 22. The rotating shaft 25 is installed in the output shaft hole of the geared motor 24. The rotating shaft 25 is driven to rotate by the geared motor 24, so that the grooved wheel 26 moves along the guide rail 3.

[0020] The screw conveyor 1 is fixedly installed between two crossbeams 22. Multiple discharge holes 11 are opened at its bottom. The rotating shaft 25 is driven by the reduction motor 24 to rotate, which can drive the screw conveyor 1 to move stably along the length of the reaction tank. Combined with the multiple discharge holes 11 at the bottom of the screw conveyor 1, the flocculant can be evenly added into the reaction tank from multiple points during the movement. This avoids the situation of excessively high or insufficient local concentration of the agent caused by fixed addition in traditional devices, which greatly improves the uniformity of flocculant distribution in wastewater, thereby ensuring the stability and reliability of flocculation and sedimentation effect and reducing agent waste.

[0021] In this embodiment, N is three. The top of the screw conveyor 1 is provided with three feed pipes 12, and three sets of storage units are respectively set above the three feed pipes 12. The storage unit includes a discharge valve 42 and a silo 41 for storing flocculant. The discharge valve 42 is installed at the bottom outlet of the silo 41, and the discharge end of the discharge valve 42 is connected to the top of the feed pipe 12. Multiple silos 41 are distributed along the screw conveyor 1. Each silo 41 is only responsible for supplying the adjacent screw conveyor section, so that the flocculant stored in the silo 41 enters the screw conveyor 1 through the feed pipe 12, shortening the flocculant conveying path, ensuring that the flocculant is evenly distributed during the conveying process, avoiding the problem of uneven conveying caused by a single feed point, and enabling the flocculant to achieve wider and more uniform diffusion in the wastewater pool, thereby improving the flocculation reaction efficiency.

[0022] The bottom of the hopper 41 is equipped with four support legs 43, which are respectively installed on two crossbeams 22, so that the hopper 41 moves synchronously with the frame unit.

[0023] The main beam 21 is made of C-shaped steel, and the crossbeam 22 is made of square and rectangular tubes, which combine high strength and lightweight characteristics, providing a stable support frame for the entire device.

[0024] In practical use, the flocculant dosing device for industrial wastewater treatment of this utility model first loads the flocculant into three sets of silos 41 one by one, ensuring that the storage capacity of each silo 41 meets the dosing requirements. Then, the three sets of discharge valves 42 are opened in sequence, and the opening is adjusted to control the discharge speed of the flocculant. The flocculant enters the screw conveyor 1 through the feed pipe 12. Then, the power of the screw conveyor 1 is turned on, driving the screw blades to rotate and pushing the flocculant evenly to the left. At the same time, the geared motor 24 is started, driving the rotating shaft 25 to rotate, driving the grooved wheel 26 to move slowly along the guide rail 3, so that the entire device moves at a constant speed from one end of the reaction tank to the other end. The multiple discharge holes 11 opened at the bottom of the screw conveyor 1 allow the flocculant to be evenly added into the reaction tank from multiple points during the movement. Finally, when the dosing is about to end, the discharge valve 42 is closed to stop the supply of flocculant. After the residual flocculant in the screw conveyor 1 is discharged, the power of the screw conveyor 1 and the geared motor 24 is turned off.

[0025] Example 2: Based on Example 1, such as Figure 1 and Figure 2 As shown, sprockets are respectively mounted on the connecting shaft 28 and the rotating shaft 25, and the two sprockets are connected by a chain 27.
