Abstract
Description
Technical Field
[0001] This utility model relates to the field of dosing device technology, specifically a flocculant dosing device. Background Technology
[0002] Flocculants are one of the most commonly used agents in wastewater treatment and are also widely used in other industries. They are generally classified into three categories according to their chemical composition: inorganic flocculants, organic flocculants, and natural polymeric flocculants. In the process of treating wastewater, flocculants need to be injected into the wastewater tank so that the wastewater can be treated by flocculation.
[0003] For example, the authorized patent with publication number CN 220703371 U (a flocculant dosing device) includes a silo and a fixing frame for fixing the silo, and also includes a cutting mechanism. The cutting mechanism includes a guide rail fixed in the silo and a movable frame that can slide on the guide rail. A blade is fixed on the top of the movable frame. It also includes a screen plate fixed in the silo and an air outlet set on the side wall of the silo. The screen plate is set above the cutting mechanism. A strip channel is set in the middle of the screen plate. The blade can pass through the strip channel to cut the cloth bag. The air outlet is located below the cutting mechanism.
[0004] While the aforementioned existing technologies facilitate dust prevention when pouring flocculants, they lack a dispersion structure during flocculant output. Consequently, when adding flocculants to wastewater tanks, the flocculants cannot be dispersed, affecting wastewater flocculation efficiency. Therefore, there is an urgent market need to develop a flocculant dosing device to help solve these existing problems. Utility Model Content
[0005] The purpose of this invention is to provide a flocculant dosing device to solve the problem mentioned in the background art that the flocculant cannot be dispersed when added to a sewage tank.

[0012] Preferably, mounting plates are fixedly installed on both sides of the front and rear ends of the device housing.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model, by setting a dispersion component below the dosing pipe, includes a frustum, a base plate, and multiple convex plates. When the flocculant is output through the dosing pipe, it falls onto the dispersion component. With the help of the structural design of the frustum and multiple convex plates, the flocculant can be effectively dispersed, allowing it to be dispersed and added into the sewage tank. This dispersed dosing method effectively avoids the problem of concentrated flocculant dosing caused by the lack of a dispersion structure in traditional devices, thereby significantly improving the sewage flocculation efficiency and ensuring the sewage treatment effect.
[0015] (2) The present invention uses a mixing component symmetrically arranged on both sides of the device box, including a mixing shaft and mixing blades. The mixing shaft is driven to rotate by an electric motor, which in turn drives the mixing blades to fully stir the flocculant. This ensures that the flocculant is uniformly mixed in the mixing chamber, thereby improving the activity and performance of the flocculant.
[0016] (3) This utility model uses a second electric motor installed above the output square tube, which is connected to the cone-shaped part of the dispersion component via a transmission shaft to drive the dispersion component to rotate. This allows the dispersion component to rotate actively during the flocculant addition process, further enhancing the dispersion effect of the flocculant and increasing its practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4This utility model provides an embodiment of a flocculant dosing device, comprising a device housing 1. In actual use, the device housing 1 is installed above a sewage tank. The device housing 1 has a mixing chamber 101 and a bottom chamber 102 respectively. A partition 7 is fixedly installed between the mixing chamber 101 and the bottom chamber 102 inside the device housing 1. An electric valve 8 is fixedly installed below the partition 7. A drop pipe 9 is fixedly installed below the electric valve 8. An output square pipe 10 is fixedly installed below the drop pipe 9. The two ends of the output square tube 10 extend to the two sides of the device housing 1, respectively. The two sides below the output square tube 10 are symmetrically fixedly installed with feeding tubes 11. A dispersion component 12 is provided below the feeding tube 11. The dispersion component 12 includes a cone 1201, a base plate 1202 and a convex plate 1203. The cone 1201 is fixedly installed in the middle above the base plate 1202. Multiple convex plates 1203 are provided. Multiple convex plates 1203 are fixedly installed above the base plate 1202 and located outside the cone 1201.
[0024] When the electric valve 8 is opened, the flocculant enters the output square pipe 10 through the drop pipe 9, and then falls onto the dispersion component 12 through the dosing pipe 11. Utilizing the structure of the frustum 1201 and multiple protruding plates 1203, the flocculant is dispersed, allowing it to be dispersed and added into the wastewater tank. This avoids the problem of concentrated flocculant addition caused by the lack of a dispersion structure in traditional devices, thereby improving wastewater flocculation efficiency and ensuring effective wastewater treatment.
[0025] Please see Figure 3 The mixing components 13 are symmetrically arranged on both sides inside the device housing 1. The mixing components 13 include a mixing shaft 1301 and mixing blades 1302. Multiple sets of mixing blades 1302 are provided, and the mixing blades 1302 are fixedly installed on the outside of the mixing shaft 1301. The upper end of the mixing shaft 1301 is rotatably connected to the device housing 1. Motors 4 are symmetrically fixedly installed on both sides above the device housing 1. The output end of the motors 4 is fixedly connected to the mixing shaft 1301.
[0026] The mixing shaft 1301 is driven to rotate by the electric motor 4, which in turn drives the mixing blades 1302 to rotate, thus stirring the mixing chamber. This allows the flocculant powder to be mixed with the water before being added, improving the activity and effectiveness of the flocculant and increasing its practicality.
[0027] Please see Figure 2An electric valve 2 is fixedly installed in the middle of the upper part of the device housing 1. A feed hopper 3 is fixedly installed above the electric valve 2. An equipment box 5 is fixedly installed on one side of the device housing 1. A vacuum pump 14 is fixedly installed inside the equipment box 5. An air extraction pipe 15 is fixedly installed at the input end of the vacuum pump 14. One end of the air extraction pipe 15 extends into the mixing chamber 101 of the device housing 1 and is fixedly installed with a filter head 16. A grid plate 17 is fixedly installed on one side of the equipment box 5.
[0028] By setting up an electric valve 2 and a feed hopper 3, and installing a vacuum pump 14 in the equipment box 5, the mixing chamber 101 is evacuated through the air extraction pipe 15 and the filter head 16 to maintain a negative pressure environment in the mixing chamber 101, which is beneficial to the stability of the flocculant when it is added to the mixing chamber 101.
[0029] Please see Figure 3 Motor 18 is symmetrically fixedly installed on both sides above the output square tube 10. A drive shaft 19 is installed above the dispersion component 12. The lower end of the drive shaft 19 is fixedly connected to the cone 1201, and the upper end of the drive shaft 19 is fixedly connected to the output end of the motor 18.
[0030] During the flocculant addition process, the transmission shaft 19 is driven to rotate by the electric motor 18, which enables the dispersion component 12 to rotate, thereby enhancing the dispersion effect of the flocculant.
[0031] Please see Figure 1 Mounting plates 6 are fixedly installed on both sides of the front and rear ends of the device housing 1.
[0032] The mounting plate 6 has bolt holes inside, which facilitates the installation of the device above the sewage tank, increasing its practicality.
[0033] Working principle: During use, the device housing 1 is fixed above the sewage tank by the mounting plate 6. The flocculant powder enters the mixing chamber 101 from the feed hopper 3 through the electric valve 2. At this time, the vacuum pump 14 maintains the negative pressure environment in the mixing chamber 101 through the air extraction pipe 15 and the filter head 16 to ensure stable feeding. Then, water is injected, and the mixing shaft 1301 is driven by the electric motor 4 to drive the mixing blades 1302 to rotate, so that the flocculant and water are mixed. The mixed flocculant solution enters the output square pipe 10 through the electric valve 8 and the drop pipe 9, and is diverted to the two side dosing pipes 11. At the same time, the electric motor 18 drives the dispersion component 12 to rotate through the transmission shaft 19. The flocculant falls onto the rotating cone 1201 and the convex plate 1203 and is dispersed in multiple directions, evenly sprinkled into the sewage tank, which increases its practicality.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
