Description

Technical Field

[0001] This utility model relates to the field of biogas digester raw material transportation, specifically to a novel double-helix dry feeding device. Background Technology

[0002] The feed screw is an essential component in the biogas production process. It stably, evenly, and orderly delivers fermentation raw materials into the biogas digester, ensuring the continuity and stability of the fermentation process and avoiding fermentation fluctuations caused by uneven feeding, thus contributing to stable biogas production. However, existing single-shaft screw feeders are clearly insufficient for large-scale biogas projects, and sometimes material accumulation on the screw surface can cause blockages, hindering the stable and uniform delivery of materials.

In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0023] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0024] like Figures 1 to 8 As shown, a novel double-screw dry feeding device includes a base 1, which has a pushing chamber 11 and a discharge channel 12. A twin-screw member 3 and a feeding component are rotatably connected in the discharge channel 12. The pushing chamber 11 has a feeding component, which includes a feeding hopper 4 at the upper end of the base 1 and a pushing component 5 below the feeding hopper 4. The pushing component 5 is used to push the material into the twin-screw member 3. A feeding adjustment component 6 is provided between the pushing component 5 and the twin-screw member 3. The feeding adjustment component 6 is used to adjust the size of the channel through which the material enters the twin-screw member 3.

[0025] In this embodiment, the pusher 5 pushes the material from the feed hopper 4 to the twin-screw 3, achieving efficient material conveying. The rotating design of the twin-screw 3 not only facilitates further material propulsion but also enables preliminary mixing of the material during conveying, improving production efficiency and product quality. The feed adjustment component 6 allows for adjustment of the channel size through which the material enters the twin-screw 3. This design allows operators to precisely control the material feed rate according to actual production needs, avoiding production problems caused by excessive or insufficient feed, such as material blockage or low production efficiency, thereby improving production flexibility and stability.

[0026] In some embodiments, the base 1 is provided with a material placement cavity 13, the material placement cavity 11 is located below the feed hopper 4, the material pusher 5 includes a material pusher block 51 and a telescopic material pusher drive 52 connected to the material pusher block 51, the telescopic material pusher drive 52 is disposed in the material placement cavity 13; when the material pusher block 51 is fully extended, it is located in the material pusher cavity 11, and when the material pusher block 51 is fully retracted, it is located in the material placement cavity 13.

[0027] In this embodiment, a dedicated material placement cavity 13 is provided within the base 1, in which the telescopic material pusher drive 52 is housed, achieving effective utilization and rational layout of the internal space of the equipment. This design avoids direct interference between the drive components and the material conveying path, ensuring smooth material conveying and facilitating equipment maintenance and repair. The material pusher 5 employs a combination design of a material pusher block 51 and a telescopic material pusher drive 52, making the material pushing process more precise and controllable. The telescopic material pusher drive 52 can precisely control the extension and retraction of the material pusher block 51, ensuring that the material enters the material pusher cavity 11 at a predetermined amount and speed, and is then pushed to the twin-screw component 3, improving the accuracy and stability of production. When the material pusher block 51 is fully retracted, it is located within the material placement cavity 13, a design that helps reduce material residue on the material pusher 5. When the material pusher block 51 is not working, its fully retracted state prevents material from remaining on the surface of the material pusher block 51 for an extended period, thereby reducing the risk of material contamination and ensuring the hygienic quality of the product.

[0028] In some embodiments, the base 1 is provided with at least one pusher limiting groove 14, and the pusher block 51 is connected with a corresponding pusher limiting slider 511, which is slidably connected to the pusher limiting groove 14.

[0029] In this embodiment, the sliding connection design between the pusher limiting groove 14 and the pusher limiting slider 511 provides precise guidance for the movement of the pusher block 51. When the pusher block 51 retracts under the action of the telescopic pusher drive 52, the pusher limiting slider 511 slides along the pusher limiting groove 14, ensuring that the pusher block 51 always moves along a predetermined straight trajectory, avoiding deviation or wobbling during the movement, and improving the accuracy and stability of the pusher. This sliding connection structure enhances the structural stability between the pusher 5 and the base 1. The cooperation between the pusher limiting slider 511 and the pusher limiting groove 14 provides additional support and constraint to the pusher block 51 during movement, reducing structural deformation or loosening caused by external forces or its own vibration, and improving the overall reliability and service life of the equipment.

[0030] In some embodiments, the pusher 5 includes a pusher stirring rod 53 rotatably connected in the pusher cavity 11 and a plurality of rod blades 54 connected to the pusher stirring rod 53. One end of the pusher stirring rod 53 is connected to a pusher stirring motor 55, and the pusher stirring motor 55 is connected to the outside of the base 1.

[0031] In this embodiment, the combined design of the pusher stirring rod 53 and the blade 54 agitates the material during the pushing process. This agitation can break up any lumps that may be present in the material, making it more loose and uniform. This facilitates more efficient conveying and mixing of the material by the subsequent twin-screw assembly 3, improving the overall process effect. It is particularly effective for pre-treating materials that are prone to caking or have high viscosity.

[0032] In some embodiments, the feeding adjustment member 6 includes an adjustment slider 61 disposed between the pushing chamber 11 and the discharging channel 12. The adjustment slider 61 is used to increase the channel between the pushing chamber 11 and the discharging channel 12 when rising and decrease the channel between the pushing chamber 11 and the discharging channel 12 when falling.

[0033] In this embodiment, the adjusting slider 61 can flexibly and precisely change the channel size between the feeding chamber 11 and the discharge channel 12 by rising or falling. This adjustability allows operators to quickly and accurately adjust the feed flow rate according to actual production needs, such as the characteristics of different materials and production speed requirements, ensuring the stability and efficiency of the production process and avoiding production problems caused by improper feed flow rate, such as material accumulation or low production efficiency. Since different materials have different flowability, particle size, and density characteristics, their feed flow rate requirements also vary. This design of the feed adjusting component 6 allows the equipment to easily adapt to various materials and different process requirements. By adjusting the position of the adjusting slider 61, the flow rate and speed of material entering the twin-screw assembly 3 can be optimized, thereby improving product quality and production efficiency and broadening the application range of the equipment.

[0034] In some embodiments, the base 1 is provided with an adjustment slide 17, the adjustment slider 61 is slidably connected to the adjustment slide 17, the adjustment slider 61 is threadedly connected to an adjustment screw 62, the adjustment screw 62 is connected to an adjustment motor 63, and the adjustment motor 63 is fixed to the upper end of the base 1.

[0035] In this embodiment, the adjusting slider 61 is slidably connected to the adjusting slide 17, and in conjunction with the threaded drive of the adjusting screw 62, the adjusting slider 61 can move precisely and stably within the adjusting slide 17. This mechanical transmission method has high precision and stability, ensuring the accuracy of the channel size adjustment between the pushing chamber 11 and the discharge channel 12, thereby achieving precise control of the feed flow rate.

[0036] In some embodiments, a limit adjustment block 611 is connected to the adjustment slider 61, and the limit adjustment block 611 is slidably connected to the adjustment slide 17.

[0037] In this embodiment, the limiting adjustment block 611 is slidably connected to the adjustment slide 17, which can enhance the stability of the adjustment slider 61 during the sliding process of the adjustment slide 17.

[0038] In some embodiments, the discharge channel 12 is located at the bottom of the base 1, and a discharge hopper 7 is provided at one end of the discharge channel 12. The twin screw 3 includes a first screw 31 and a second screw 33 rotatably connected in the discharge channel 12. The first screw 31 and the second screw 33 are used to transport materials from the end away from the discharge hopper 7 to the discharge hopper 7.

[0039] In this embodiment, the twin-screw assembly 3 includes a first screw 31 and a second screw 33. The two screws rotate within the discharge channel 12, enabling them to fully shear, compress, and mix the material. This mixing action helps break down the agglomeration structure within the material, making the material more uniform and improving the homogenization of the product, which is particularly important for the production of products requiring high uniformity.

[0040] In some embodiments, the twin-screw member 3 includes a first motor 32 connected to one end of the first screw 31 and a second motor 34 connected to one end of the second screw 33. A motor protective cover 35 is connected to the base 1, and the motor protective cover 35 is located on the upper side of the first motor 32 and the second motor 34.

[0041] In this embodiment, the independently driven twin-screw assembly 3 can better adapt to the conveying and mixing requirements of different materials. By adjusting the speed difference between the two screws, different shear forces and mixing effects can be generated, which helps to break up the agglomeration structure of materials, making the materials more uniformly mixed and improving the homogenization of the product. At the same time, this design also helps to reduce blockage and stagnation of materials during the conveying process, ensuring the smooth operation of the production process. The motor protective cover 35 connected to the base 1 is located above the first motor 32 and the second motor 34, providing effective safety protection for the motors. It can prevent external objects from accidentally falling into the motors, causing damage or safety accidents. At the same time, the motor protective cover 35 also plays a certain role in dust and water protection, extending the service life of the motors and improving the safety of the equipment.

[0042] In some embodiments, a support frame 15 is connected to the bottom of the base 1, a support leg 2 is connected to the support frame 15, and a weight sensor 8 is connected between the support frame 15 and the support leg 2.

[0043] In this embodiment, the weight sensor 8 is connected between the support frame 15 and the support leg 16, enabling precise real-time weighing and monitoring of the base 1 and its internal materials. During production, operators can obtain the equipment's weight data at any time to understand the amount of material input, output, and overall load of the equipment, providing strong support for precise control of the production process and offering effective reference for subsequent material additions.

[0044] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The material is pushed from the feed hopper to the twin-screw extruder by a pusher, achieving efficient material conveying. The rotational design of the twin-screw extruder not only facilitates further material propulsion but also enables initial mixing of materials during conveying, improving production efficiency and product quality. The feed adjustment mechanism allows for adjustable material entry channels into the twin-screw extruder. This design allows operators to precisely control the material feed rate according to actual production needs, avoiding production problems such as material blockage or low production efficiency caused by excessive or insufficient feed, thereby improving production flexibility and stability. This design also addresses the problem of material accumulation at the feed end of existing twin-screw extruder structures, which can negatively impact the stability of subsequent material conveying.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
