Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a flocculant dispensing device. Background Technology

[0002] Water treatment methods include physical treatment and chemical treatment. Humans have been treating water for a long time. Physical methods include using filter media with different pore sizes to remove impurities from the water through adsorption or blocking. Among adsorption methods, activated carbon is the most important. Blocking methods involve passing water through filter media to prevent larger impurities from passing through, thus obtaining cleaner water. Flocculants are also used to assist in water purification.

[0003] Flocculants can be broadly classified into two categories based on their chemical composition: inorganic flocculants and organic flocculants. Inorganic flocculants include inorganic coagulants and inorganic polymeric flocculants; organic flocculants include synthetic organic polymeric flocculants, natural organic polymeric flocculants, and microbial flocculation.

[0004] Utility model patent CN221492361U discloses a flocculant dispensing device. Through the cooperation of a motor and transmission components, a connecting block drives two stirring rods within the tank to rotate, facilitating thorough mixing of the flocculant powder and solution. This also reduces the possibility of the flocculant agglomerating due to prolonged storage. A water pump and spraying components then spray the flocculant solution into the wastewater tank, facilitating its dispensing. However, in practice, this solution cannot allow for intermittent flocculant dispensing. Excessive dispensing leads to flocculant waste, while insufficient dispensing may fail to achieve the desired sedimentation effect in wastewater treatment. Therefore, this invention proposes a flocculant dispensing device to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a flocculant dosing device that has the advantage of intermittent dosing, thus solving the technical problems of waste caused by excessive flocculant dosing or insufficient dosing failing to achieve the sedimentation effect in wastewater treatment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flocculant dispensing device includes a dispensing box with a partition dividing the interior of the dispensing box into an upper chamber and a lower chamber. A dispensing port communicating with the lower chamber is located outside the dispensing box, and a discharge port is located at the bottom. A movable rod is installed inside the dispensing box, passing through and slidably connected to the partition. A motor is installed at the top of the dispensing box, and a rotating rod is installed at the motor's output end. A movable rod is mounted on the rotating rod, and a blocking member is installed at the bottom of the movable rod. A fixing member is installed inside the upper chamber, abutting against the movable rod to control its vertical movement.

[0008] Furthermore, the fixing component includes a fixing seat, on which a connecting rod is fixedly mounted, and at the end of the connecting rod is a spherical component. A guide groove is arranged around the upper outer surface of the movable rod, and the spherical component is located in the guide groove and slidably connected thereto.

[0009] Furthermore, the guide groove includes a wave groove, and the first and last ends of the wave groove are connected by arc-shaped grooves.

[0010] Furthermore, the movable rod is sleeve-shaped and is sleeved outside the rotating rod. The movable rod is provided with a protrusion, and the protrusion is provided with a corresponding guide hole on the rotating rod.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: the device uses a rotating rod with a movable rod outside the rotating rod set at the motor output end, and the protrusion on the movable rod can drive the rotating rod to rotate synchronously along the guide through hole set on the rotating rod; by setting a guide groove on the outer periphery of the movable rod, when the fixed part abuts against the guide groove, the rotating rod can be controlled to move up and down at the same time as it rotates, which facilitates the intermittent addition of flocculant.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-5 This embodiment of a flocculant dispensing device includes a dispensing box 1. A partition 11 is provided inside the dispensing box 1, dividing the interior of the dispensing box 1 into an upper chamber 101 and a lower chamber 102. A dispensing port 103 is provided outside the dispensing box 1, communicating with the lower chamber 102. A discharge port 104 is provided at the bottom. A movable rod 2 is provided inside the dispensing box 1, passing through the partition 11 and slidably connected thereto. A motor 5 is provided at the top of the dispensing box 1, and a rotating rod 6 is provided at the output end of the motor 5. The movable rod 2 is provided on the rotating rod 6. A blocking member 4 is provided at the bottom of the movable rod 2. A fixing member 3 is provided inside the upper chamber 101, abutting against the movable rod 2 to control the up and down movement of the movable rod 2.

[0020] In this application, the blocking member 4 of the device is provided with a layer of elastic material. In the initial state, the blocking member 4 blocks the outlet 104.

[0021] The device is also equipped with a PLC controller, which is electrically connected to the motor 5. The flocculant is added into the lower chamber 102 through the inlet 103 for storage. When flocculant needs to be added, the PLC controller controls the motor 5 to rotate. By controlling the up and down movement of the movable rod 2, the flocculant can be added intermittently.

[0022] Furthermore, the fixing member 3 includes a fixing seat 31, on which a connecting rod 32 is fixedly mounted. A ball-shaped part 33 is provided at the end of the connecting rod 32. A guide groove 21 is arranged around the upper outer surface of the movable rod 2. The ball-shaped part 33 is located in the guide groove 21 and is slidably connected to it.

[0023] In this application, since the fixing member 3 is fixedly installed and the ball part 33 on the fixing member 3 is in contact with the guide groove 21, the ball part 33 can slide in the guide groove 21 during the rotation of the motor 5, thereby driving the movable rod 2 to move up and down.

[0024] Furthermore, the guide groove 21 includes a wave groove 201, and the first and last ends of the wave groove 201 are connected by arc-shaped grooves 202.

[0025] In this application, the device consists of a guide groove 21 divided into two parts: a corrugated groove 201 and an arc-shaped groove 202. The highest points of the arc-shaped groove 202 and the corrugated groove 201 are located on the same horizontal plane. When the spherical component 33 moves towards the highest point of the corrugated groove 201, the movable rod 2 moves downward, gradually blocking the outlet 104. When the spherical component 33 moves towards the lowest point of the corrugated groove 201, the movable rod 2 moves upward, at which point the flocculant is added. When the spherical component 33 stops moving in the area of ​​the arc-shaped groove 202, the addition of flocculant stops.

[0026] Furthermore, the movable rod 2 is sleeve-shaped and is sleeved on the outside of the rotating rod 6. The movable rod 2 is provided with a protrusion 22, and the protrusion 22 is provided with a corresponding guide hole 601 on the rotating rod 6.

[0027] In this application, the device uses the cooperation between the protrusion 22 and the guide through hole 601 to enable the motor 5 to rotate synchronously and drive the movable rod 2 to rotate. During rotation, the guide groove 21 is used to realize the up and down movement of the rotating rod 6, which facilitates the intermittent dosing control of flocculant.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
