[0023] The following will clearly and completely describe the technical solution of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 4 The present invention provides a technical solution: a raw material stirring device for producing water treatment agent particles, comprising a stirring drum 1, a feeding port 8 being provided in the middle of the top surface of the stirring drum 1, a stirring shaft 14 being coaxially provided in the stirring drum 1, and both ends of the stirring shaft 14 being rotatably connected to the ends of the stirring drum 1. Figure 1 As shown, a horizontal opening 19 is provided in the middle of the mixing drum 1. The opening is provided through the entire mixing drum 1, so that the mixing drum 1 is divided into two parts, the upper and lower parts. The mixing shaft 14 is provided in the lower part of the mixing drum 1, and the feed port 8 is provided in the middle of the top surface of the upper part of the mixing drum 1.

[0025] The lower and upper opening edges of the mixing drum 1 are both provided with connecting skirts 2, which are connected by locking members, specifically bolts. Because the mixing shaft 14 is mounted with mixing blades 17, maintenance and inspection are required during long-term mixing. To do this, the bolts can be removed and the upper portion of the mixing drum 1 removed, exposing the mixing shaft for easy inspection and maintenance.

[0026] The most important thing about this application is that the two ends of the mixing drum 1 are designed to be respectively converging into a conical structure. This has the advantage that when the water treatment agent particles to be mixed are poured through the feed port, the mixing drum 1 forms a slope from the middle to its two sides due to the small diameter at the two ends and the large diameter in the middle. As a result, the water treatment agent particles inside the mixing drum 1 automatically slide along the slope toward the middle of the mixing drum 1.

[0027] Two sets of stirring blades 17 are mounted on the stirring shaft 14. The two sets of stirring blades 17 are symmetrically arranged in the middle of the stirring shaft 14, and the ends facing away from each other are arranged in a conical shape. The shape of the two sets of stirring blades 17 matches the conical structure. Therefore, the arrangement of the stirring blades 17 matches the shape of the mixing drum 1, allowing the stirring blades 17 to evenly stir the particles in the mixing drum 1. Moreover, each set of stirring blades 17 is multiple and has a spiral structure. Each stirring blade 17 is connected to the stirring shaft 14 via multiple connecting rods 18, and the two sets of stirring blades 17 rotate in opposite directions. When in use, the stirring blades 17 rotate toward the middle of the mixing drum 1, so that the mixing drum 1 can drive the particles to gather in the middle of the mixing drum 1 when it rotates.

[0028] The bottom of the mixing drum 1 is provided with a bracket, which includes support legs 3, respectively, arranged at both ends of the bottom of the mixing drum 1. There are at least two support legs 3, which are arranged symmetrically. A connecting seat 5 is provided below the mixing drum 1. The two ends of the connecting seat 5 are connected to the reinforcing seat 4. The reinforcing seat 4 is located between the support legs 3 and the two are connected to each other. The connection seat 5 can strengthen the strength between the support legs on both sides. Among them, one end of the mixing shaft 14 is connected to the drive mechanism.

[0029] The driving mechanism of the present application will be described in detail below. The driving mechanism includes a gearbox 12 and a drive motor 20 connected to the input end of the gearbox 12. The output shaft of the gearbox 12 is connected to the transmission shaft 13. The gearbox 12 and the drive motor 20 are both mounted on the connecting seat 5, and the transmission shaft 13 is placed between the support legs 3. A bearing support 16 is provided on the top of the reinforcing seat 4. The transmission shaft 13 is rotatably mounted in the bearing support 16 so that the transmission shaft 13 is supported by the bearing support 16, which makes the transmission shaft 13 more supportable. The transmission shaft 13 is located below the end of the stirring shaft 14. The ends of the stirring shaft 14 and the ends of the transmission shaft 13 are both provided with transmission wheels 15. The transmission wheels 15 are connected by a conveyor belt. The transmission wheel 15 here is one of a pulley, a synchronous wheel or a sprocket, and the corresponding conveyor belt is a belt, a synchronous belt or a transmission chain. Therefore, when the driving motor rotates, it can drive the transmission shaft to rotate through the gearbox, and the transmission shaft 13 drives the stirring shaft 14 to rotate through the conveyor belt.

[0030] Specifically, the above-mentioned specific mixing process is that after the water treatment agent particles are poured into the mixing drum 1, the particles will flow along the inclined surface of the inner wall of the mixing drum 1 to the middle of the mixing drum 1 and gather. When the mixing blades 17 rotate, it can drive the particles to stir continuously, and the rotating mixing blades can also drive the particles to flow toward the middle of the mixing drum 1, so that the particles on both sides of the mixing drum 1 are driven by the two groups of mixing blades 17 and rush toward the middle of the mixing drum at the same time, so that the two flowing particles collide with each other, causing the particles to be stirred circumferentially while there is also opposite flow to form a counter-flow, so that the particles in the mixing drum 1 can be quickly and evenly stirred.

[0031] The stirred particle mixture needs to be discharged outward, so a discharge port (not shown in the figure) is provided in the middle of the bottom of the mixing drum 1. The structural characteristics of the mixing drum 1 of the present application also contribute to the discharge of the particles, that is, the particles will automatically gather toward the discharge port. A discharge mechanism is provided on the discharge port, and the discharge mechanism includes a screw conveying shaft 6 installed below the discharge port. The discharge end of the screw conveying shaft 6 is inclined downward, and a valve (such as Figure 1 When discharging, the stirring blades continuously convey the material toward the outlet, so that the spiral conveying shaft 6 continuously discharges the stirred material outward;

[0032] It should be noted that the forward rotation of the screw conveying shaft 6 can quickly discharge the particles outward, and when the screw conveying shaft 6 rotates in the reverse direction, it can convey the material upward. Therefore, during the stirring process of the mixing drum 1, the screw conveying shaft 6 can be turned on to rotate in the reverse direction, so that the material falling into the screw conveying shaft 6 can flow upward continuously, so that a small amount of particles entering the screw conveying shaft 6 can also flow upward, so that this part of the particles can also be stirred.

[0033] Further, such as Figure 1 and Figure 2 As shown, a protective cover 10 is provided at one end of the mixing drum 1 close to the transmission wheel 15. The protective cover 10 covers the transmission wheel 15 and the transmission belt, and the upper and lower ends of both sides of the protective cover 10 are respectively connected to the mixing drum 1 and the reinforcement seat 4 through the connecting frame 9. The protective cover 10 can prevent the transmission wheel from being exposed and prevent external debris from being stirred into the transmission wheel during use.

[0034] Further, such as Figure 1 and Figure 2 As shown, the top opening of the feed port 8 is sealed by a cover plate 7. Dust will be generated during stirring. After the cover plate is covered, the dust during the stirring process can be prevented from overflowing into the air.

[0035] Further, such as Figure 1 and Figure 2 As shown, a protective cover 10 is provided at one end of the mixing drum 1 close to the transmission wheel 15. The protective cover 10 covers the transmission wheel 15 and the transmission belt, and the upper and lower ends of both sides of the protective cover 10 are respectively connected to the mixing drum 1 and the reinforcement seat 4 through the connecting frame 9. The protective cover 10 can prevent the transmission wheel from being exposed and prevent external debris from being stirred into the transmission wheel during use.

[0036] Based on the above embodiment, further optimization can be performed, such as Figure 1 As shown, an electric control cabinet 11 is installed on the support leg 3, and an electric control device is provided in the electric control cabinet 11 to facilitate the control of the start-up of the drive motor.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
