Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a uniform feeding device for raw material tanks. Background Technology

[0002] In industrial production, the feeding process of raw material tanks is one of the key steps to ensure production continuity and product quality stability. Currently, traditional raw material tank feeding devices face several problems in practical applications that urgently need to be addressed. On the one hand, for the addition of multi-component raw materials, the amount of raw materials added by the existing equipment still relies on manual control, resulting in insufficient accuracy of the ratio of each raw material, which directly affects the quality stability of the subsequent products.

[0003] On the other hand, the mixing effect of multi-component raw materials before entering the raw material tank is poor. In traditional equipment, different raw materials are usually discharged directly into the raw material tank through their respective feeding channels, relying solely on the natural mixing of the raw materials' own gravity and the space inside the tank, resulting in low mixing uniformity. To achieve the mixing effect required by the process, additional stirring equipment is often required to perform secondary stirring of the raw materials in the tank, which not only increases equipment investment and energy consumption, but also prolongs the production cycle and reduces overall production efficiency.

[0004] To address the aforementioned issues, we propose a uniform feeding device for raw material tanks. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a uniform feeding device for raw material tanks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A uniform feeding device for a raw material tank includes a raw material tank and a feeding mechanism. The feeding mechanism includes a top cover, a discharge pipe fixedly installed at the center of the top cover, a material gathering cylinder fixedly installed at the upper end of the discharge pipe, a plurality of discharge branch pipes fixedly installed circumferentially on the side wall of the material gathering cylinder, a feeding cone fixedly installed at the upper end of the discharge branch pipe, a rotating shaft rotatably arranged inside the discharge pipe, a spiral blade fixedly installed on the side wall of the rotating shaft, a conical disc fixedly installed at the lower end of the rotating shaft, a plurality of arc-shaped dispersing blades fixedly installed circumferentially on the upper side of the conical disc, and a plurality of liquid outlet holes opened on the conical disc.

[0007] Furthermore, a first solenoid valve is fixedly installed at the bottom of the feeding cone.

[0008] Furthermore, the top cover is fixedly installed on the upper side of the raw material tank, a stabilizing cylinder is fixedly installed on the upper side of the material collection cylinder, the upper end of the rotating shaft is rotatably installed inside the stabilizing cylinder, a motor is fixedly installed on the upper end of the stabilizing cylinder, and the output end of the motor is connected to the rotating shaft coupling.

[0009] Furthermore, a bottom support rod is fixedly installed on the lower side wall of the feeding pipe, and an insertion hole is opened at the center of the bottom of the cone plate, and the bottom support rod is rotatably inserted into the inner side of the insertion hole.

[0010] Furthermore, a number of ball bearings are embedded in the inner wall of the socket, and a sealing rubber ring is installed at the socket port.

[0011] Furthermore, a discharge pipe is fixedly installed at the bottom of the raw material tank, and a second solenoid valve is fixedly installed on the discharge pipe.

[0012] Furthermore, a controller is fixedly installed on the side wall of the raw material tank.

[0013] Furthermore, several support legs are fixedly installed at the bottom of the raw material tank, and rubber pads are fixedly installed at the bottom of the support legs.

[0014] Compared with related technologies, the raw material tank uniform feeding device proposed in this utility model has the following beneficial effects: In this invention, a uniform feeding device for a raw material tank is described. Different raw materials are fed into multiple sets of feeding cones in the feeding mechanism. A first solenoid valve at the bottom of each cone, with its opening time controlled by a controller, precisely controls the amount of each component material being fed. After initial mixing via a feeding branch pipe, the raw materials converge into a collecting cylinder and then flow into the feeding pipe. During feeding, a motor drives the spiral blades on the outside of the rotating shaft to rotate, achieving further mixing while conveying the raw materials. As the mixed raw materials flow out of the feeding pipe, the rotating shaft simultaneously drives a cone disk equipped with arc-shaped dispersing blades to rotate, evenly dispersing the raw materials and dispersing them into the raw material tank. The entire feeding process simultaneously achieves precise quantity control, multi-stage mixing, and uniform dispersion, effectively improving the uniformity of raw material mixing and significantly increasing production efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Reference Figures 1-7 A uniform feeding device for a raw material tank includes a raw material tank 1 and a feeding mechanism 5. The feeding mechanism 5 includes a top cover 51, a discharge pipe 52 fixedly installed at the center of the top cover 51, a material gathering cylinder 53 fixedly installed at the upper end of the discharge pipe 52, a plurality of discharge branch pipes 54 fixedly installed at equal intervals around the side wall of the material gathering cylinder 53, a feeding cone 55 fixedly installed at the upper end of the discharge branch pipes 54, a rotating shaft 58 rotatably arranged inside the discharge pipe 52, a spiral blade 510 fixedly installed on the side wall of the rotating shaft 58, a cone disc 511 fixedly installed at the lower end of the rotating shaft 58, a plurality of arc-shaped dispersing blades 512 fixedly installed at equal intervals around the upper side of the cone disc 511, and a plurality of liquid outlet holes 513 opened on the cone disc 511.

[0019] With the above configuration, when the raw material fluid flows from the converging cylinder 53 through the discharge pipe 52, the motor 517 drives the rotating shaft 58 to rotate. When the spiral blades 510 rotate, they mix and guide the material. Several arc-shaped dispersing blades 512 are set on the upper side of the cone disk 511. When they rotate synchronously with the cone disk 511, they can disperse the raw material flowing out from the lower end of the discharge pipe 52. At the same time, some raw material will flow downward from the liquid outlet holes 513 evenly distributed on the cone disk 511, so that the raw material is dispersed into several paths and flows out and dispersed, making the raw material that re-converges to the bottom of the inner side of the raw material tank 1 more uniform.

[0020] In this method, a discharge pipe 6 is fixedly installed at the bottom of the raw material tank 1, a second solenoid valve 7 is fixedly installed on the discharge pipe 6, a controller 2 is fixedly installed on the side wall of the raw material tank 1, and several support legs 3 are fixedly installed at the bottom of the raw material tank 1, with rubber pads 4 fixedly installed at the bottom of the support legs 3.

[0021] With the above-mentioned setup, the second solenoid valve 7 is used to control the opening state of the discharge pipe 6, and the rubber pad 4 makes the support leg 3 more stable and less prone to side slippage.

[0022] In this method, a first solenoid valve 56 is fixedly installed at the bottom of the feeding cone 55.

[0023] With the above configuration, the first solenoid valve 56 is used to control the opening and closing state of the feeding cone 55.

[0024] In this method, the top cover 51 is fixedly installed on the upper side of the raw material tank 1, the upper side of the material gathering cylinder 53 is fixedly installed with a stabilizing cylinder 57, the upper end of the rotating shaft 58 is rotatably installed inside the stabilizing cylinder 57, the upper end of the stabilizing cylinder 57 is fixedly installed with a motor 517, and the output end of the motor 517 is connected to the rotating shaft 58 with a coupling.

[0025] By setting up the cylinder 57 as described above, the stability of the sleeve support on the outside of the rotating shaft 58 is improved, making the rotation of the rotating shaft 58 more stable.

[0026] In this method, a bottom support rod 59 is fixedly installed on the lower side wall of the feed pipe 52, and an insertion hole 514 is opened at the center of the bottom of the cone disc 511. The bottom support rod 59 is rotatably inserted into the inside of the insertion hole 514. Several balls 515 are embedded in the inner side wall of the insertion hole 514, and a sealing rubber ring 516 is installed at the port of the insertion hole 514.

[0027] With the above-mentioned configuration, the bottom support rod 59 provides a rotational support point for the bottom of the cone disc 511, making the lower end of the rotating shaft 58 more stable when rotating. The ball bearing 515 reduces the rotational friction between the bottom support rod 59 and the insertion hole 514.

[0028] The working principle of the uniform feeding device for raw material tank provided by this utility model is as follows: During operation, the controller 2 first presets the feeding parameters for each component raw material. Different types of raw materials are poured into their corresponding feeding cones 55. The controller 2 controls the first solenoid valve 56 at the bottom of each feeding cone 55 to open at a set time according to the preset parameters. By setting the opening time, the feeding amount of each raw material is precisely controlled. After the raw materials flow out of the feeding cones 55, they flow into the material collection cylinder 53 through the discharge branch pipe 54, where preliminary mixing is completed. The pre-mixed raw materials continue to flow downward into the discharge pipe 52. At the same time, the motor 517 is started to drive the rotating shaft 5. The rotating shaft 58 drives the spiral blade 510 to rotate. During rotation, the spiral blade 510 not only conveys the raw material downwards but also performs secondary mixing, improving the mixing uniformity. The upper end of the rotating shaft is supported by a stabilizing cylinder 57, ensuring the stability of the rotation process. After the raw material flows out from the lower end of the feed pipe 52, it falls onto the conical disk 511. Since the lower end of the rotating shaft 58 is fixedly connected to the conical disk 511, the conical disk 511 rotates together with the rotating shaft 58. The arc-shaped dispersing blade 512 above it rotates synchronously, dispersing the falling raw material. Some of the raw material will flow directly down through the liquid outlet hole 513 on the conical disk 511, falling into the raw material tank 1 together with the raw material dispersed by the arc-shaped dispersing blade 512, realizing the third mixing of the raw material.

[0029] When the amount of raw material in the raw material tank 1 reaches the required amount, the controller 2 closes each of the first solenoid valves 56 to stop feeding. When it is necessary to discharge the raw material, the controller 2 controls the second solenoid valve 7 on the discharge pipe 6 to open, and the raw material flows out from the discharge pipe 6.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
