Description

Technical Field

[0001] This utility model relates to the field of ingredient mixing technology, and in particular to a double-layer mixing hopper for uniform mixing. Background Technology

[0002] In numerous industrial production fields such as chemical, food, and pharmaceutical industries, precise and uniform mixing of various raw materials is a crucial step in ensuring product quality. Traditional single-layer batching hoppers exhibit several drawbacks in the mixing process. The mixing range of ordinary single-layer batching hoppers is limited to a confined space, making it difficult to achieve large-scale, all-around mixing of raw materials. Due to the singular mixing method, some raw materials with higher specific gravity or viscosity are prone to sedimentation and accumulation, resulting in inconsistent mixing effects and unstable product quality. This uneven mixing not only affects product performance and quality but may also lead to waste and increased costs in the production process. Therefore, we propose a double-layer batching hopper for uniform mixing to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-layer mixing hopper for uniform material mixing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A double-layer mixing hopper for uniform mixing includes a mixing tank. A protective box is fixed to the upper end of the mixing tank. A rotating device is installed inside the protective box. A fixed pipe is connected to the rotating device. A rotary joint is connected to the upper end of the fixed pipe. The lower end of the fixed pipe is rotatably sleeved on the upper side wall of the mixing tank. A rotary conveying head is connected to the lower end of the fixed pipe. Multiple spray holes are evenly spaced on the bottom and circumferential side wall of the rotary conveying head. An upper mixing hopper is installed at the upper end of the mixing tank. Multiple arc-shaped guide plates are evenly spaced on the circumferential side wall of the upper mixing hopper. Feed pipes are connected to both sides of the upper mixing hopper. A conveying pipe is connected to the lower end of the upper mixing hopper. The lower end of the conveying pipe penetrates the side wall of the protective box and is connected to the fixed end of the rotary joint. A stirring device is installed at both the upper end of the upper mixing hopper and the lower end of the mixing tank.

[0006] Preferably, the rotating device includes a second drive motor fixed inside the protective box on one side, and gears are fixedly mounted on the output shaft and the fixed tube of the second drive motor, and the two gears mesh with each other.

[0007] Preferably, the mixing device includes a first drive motor fixed at the upper end of the upper batching hopper and the lower end of the mixing tank. The output shaft of the first drive motor is connected to a stirring rod, and the stirring rod is provided with a plurality of rectangular stirring blades and spiral stirring blades at equal intervals around its circumference.

[0008] Preferably, a support frame is fixed to the upper end of the mixing tank, and the upper end of the support frame is fixed to both sides of the lower end of the upper batching hopper.

[0009] Preferably, a discharge pipe is connected to one side of the lower end of the mixing tank.

[0010] Preferably, an electric valve is installed on the delivery pipe.

[0011] In this invention, during the mixing of ingredients:

[0012] 1. Raw material input: Open the feed valve on the feed pipe, and different raw materials are fed into the upper batching hopper through multiple feed pipes;

[0013] 2. Initial mixing in the upper layer: After the raw materials enter the upper batching hopper, multiple arc-shaped guide plates fixed at equal intervals on the inner side wall of the upper batching hopper play a role. They change the flow direction of the raw materials, increase the collision and contact opportunities between the raw materials, and improve the mixing effect. At the same time, the stirring equipment at the top of the upper batching hopper is started. The first drive motor drives the stirring rod to rotate. The rectangular stirring blades and spiral stirring blades on the stirring rod stir the raw materials, further promoting the mixing of the raw materials.

[0014] 3. Raw material conveying: By adjusting the electric valve on the conveying pipe, the conveying speed of the raw materials can be controlled, so that the raw materials flow into the rotary conveyor head at a suitable speed, evenly and continuously. Precise flow control helps to ensure the stability and uniformity of the subsequent mixing process.

[0015] 4. Rotary spray mixing: The rotating device inside the protective box starts to work. The second drive motor drives the fixed tube to rotate through the meshing gears, thereby causing the rotary conveyor head connected to the fixed tube to rotate. Multiple spray holes on the bottom and one side wall of the rotary conveyor head spray out the initially mixed raw materials. During the spraying process, the raw materials are dispersed over a larger area, further improving the mixing efficiency.

[0016] 5. Further mixing in the lower layer: The stirring equipment at the bottom of the mixing tank is started. The first drive motor drives the stirring rod and the rectangular stirring blades and spiral stirring blades above to further stir and mix the raw materials falling into the mixing tank, ensuring that the raw materials reach a highly uniform mixing state.

[0017] 6. Finished product discharge: After mixing is complete, open the discharge pipe connected to the lower side of the mixing tank to discharge the mixed finished product.

[0018] This utility model has the following advantages:

[0019] 1. The combination of a double-layer design and multiple mixing methods, including the guidance of the arc-shaped guide plate, the stirring of the mixing equipment and the spraying of the rotary conveyor head, greatly expands the mixing range, effectively avoids the settling and accumulation of raw materials, and enables various raw materials to be fully mixed, significantly improving the uniformity of mixing.

[0020] 2. By rotating the conveyor head to spray out the raw materials through the rotating equipment, and by working in coordination with the upper and lower mixing equipment, the mixing speed is accelerated, the mixing time is reduced, and the production efficiency is improved.

[0021] 3. The electric valve on the conveying pipe can precisely control the conveying speed of the raw materials, ensuring that the raw materials flow into the rotary conveyor head evenly and continuously at a suitable speed, which is conducive to stabilizing the production process and improving the stability of product quality.

[0022] In summary, this invention greatly expands the mixing range, effectively avoids the settling and accumulation of raw materials, enables various raw materials to be fully mixed, significantly improves the uniformity of mixing, accelerates the mixing speed, reduces mixing time, improves production efficiency, and ensures stable product quality.

Detailed Implementation

[0028] 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.

[0029] Reference Figure 1-4A double-layer mixing hopper for uniform mixing includes a mixing tank 16. A protective box 15 is fixed to the upper end of the mixing tank 16. The protective box 15 is made of high-strength, corrosion-resistant stainless steel. It can not only provide physical protection for the internal rotating equipment to prevent collisions and damage from external objects, but also effectively block dust, water vapor and other substances from entering, ensuring the normal operating environment of the rotating equipment.

[0030] The protective box 15 is equipped with a rotating device, and a fixed pipe 6 is connected to the rotating device. The upper end of the fixed pipe 6 is connected to a rotary joint 4. The rotary joint 4 can ensure that the fixed pipe 6 can rotate flexibly while preventing raw material leakage, thus ensuring the sealing and stability of the entire conveying process.

[0031] The lower end of the fixed pipe 6 is rotatably sleeved on the upper side wall of the mixing tank 16. The lower end of the fixed pipe 6 is connected to a rotary conveyor head 10. Multiple spray holes 9 are provided at equal intervals on the bottom and the side wall of the rotary conveyor head 10. The size of the spray hole 9 is precisely designed and optimized according to the characteristics of different raw materials and mixing requirements to ensure that the raw materials can be sprayed out at a suitable speed and angle to achieve the best mixing effect.

[0032] The upper end of the mixing tank 16 is equipped with an upper feeding hopper 3. Multiple arc-shaped guide plates 18 are fixed at equal intervals on the circumferential side wall inside the upper feeding hopper 3. The arc and surface smoothness of the arc-shaped guide plates 18 are designed to change the flow direction of the raw materials to the greatest extent, so that the raw materials form complex turbulence during the flow process, increase the collision and contact opportunities between the raw materials, and thus improve the mixing effect.

[0033] Feed pipes 2 are connected to both sides of the upper batching hopper 3. A conveying pipe 5 is connected to the lower end of the upper batching hopper 3. The lower end of the conveying pipe 5 passes through the side wall of the protective box 15 and is connected to the fixed end of the rotary joint 4. Agitators are installed at the upper end of the upper batching hopper 3 and the lower end of the mixing tank 16. During the agitation process, the speed of the first drive motor 1 can be adjusted according to the characteristics of the raw materials and the mixing requirements to achieve the best agitation effect. The agitation time also needs to be reasonably controlled according to the actual situation to ensure that the raw materials are fully and initially mixed in the upper batching hopper 3.

[0034] The rotating device includes a second drive motor 7 fixed inside the protective box 15. Gears 8 are fixedly mounted on the output shaft and the fixed tube 6 of the second drive motor 7, and the two gears 8 mesh with each other. The stirring device includes a first drive motor 1 fixed at the upper end of the upper batching hopper 3 and the lower end of the mixing tank 16. The output shaft of the first drive motor 1 is connected to a stirring rod 12. Multiple rectangular stirring blades 19 and spiral stirring blades 11 are evenly spaced around the stirring rod 12. The shape and layout of the rectangular stirring blades 19 and the spiral stirring blades 11 are optimized. The rectangular stirring blades 19 can stir and turn the raw materials over a large area, while the spiral stirring blades 11 can make the raw materials circulate in the vertical direction. The two work together to further promote the mixing of the raw materials.

[0035] A support frame 13 is fixed to the upper end of the mixing tank 16. The upper end of the support frame 13 is fixed to both sides of the lower end of the upper batching hopper 3. A discharge pipe 17 is connected to one side of the lower end of the mixing tank 16. A flow regulating valve is installed on the discharge pipe 17 to facilitate the operator to control the discharge speed of the finished product according to actual needs and improve the flexibility of production.

[0036] An electric valve 14 is installed on the conveying pipe 5. The electric valve 14 adopts an advanced electronic control system, which can accurately control the opening of the valve, thereby achieving precise adjustment of the raw material conveying speed and ensuring the stability and uniformity of the subsequent mixing process.

[0037] In this invention, during the mixing of ingredients:

[0038] 1. Raw material input: Open the feed valve on the feed pipe 2, and different raw materials are fed into the upper batching hopper 3 through multiple feed pipes 2 respectively;

[0039] 2. Initial mixing in the upper layer: After the raw materials enter the upper batching hopper 3, multiple arc-shaped guide plates 18 fixed at equal intervals on the inner side wall of the upper batching hopper play a role. They change the flow direction of the raw materials, increase the collision and contact opportunities between the raw materials, and improve the mixing effect. At the same time, the stirring equipment at the upper end of the upper batching hopper 3 is started. The first drive motor 1 drives the stirring rod 12 to rotate. The rectangular stirring blades 19 and the spiral stirring blades 11 on the stirring rod stir the raw materials, further promoting the mixing of the raw materials.

[0040] 3. Raw material conveying: By adjusting the electric valve 14 on the conveying pipe 5, the conveying speed of the raw material can be controlled, so that the raw material flows into the rotary conveying head 10 at a suitable speed, evenly and continuously. Precise flow control helps to ensure the stability and uniformity of the subsequent mixing process.

[0041] 4. Rotary spray mixing: The rotating device inside the protective box 15 starts to work. The second drive motor 7 drives the fixed tube 6 to rotate through the meshing gears 8, thereby causing the rotary conveyor head 10 connected to the fixed tube to rotate. Multiple spray holes 9 on the bottom and one side wall of the rotary conveyor head 10 spray out the initially mixed raw materials. During the spraying process, the raw materials are dispersed over a larger area, further improving the mixing efficiency.

[0042] 5. Further mixing in the lower layer: The stirring device at the lower end of the mixing tank 16 is started. The first drive motor 1 drives the stirring rod 12 and the rectangular stirring blade 19 and the spiral stirring blade 11 above to further stir and mix the raw materials falling into the mixing tank, ensuring that the raw materials reach a highly uniform mixing state.

[0043] 6. Finished product discharge: After mixing is completed, open the discharge pipe 17 connected to the lower side of the mixing tank 16 to discharge the mixed finished product.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
