Description

Technical Field

[0001] The present invention relates to the technical field of pneumatic conveying, and particularly to a chicken liver powder conveying system based on a multi-directional pneumatic channel. Background Art

[0002] The production process of chicken liver powder involves multiple links such as cleaning, crushing, mixing, drying, and pulverizing. The mixing process of additives and chicken liver powder is carried out through a conveying system for synchronous mixing. Traditional conveying systems mostly adopt mechanical spiral conveying or open pipelines, and there are the following problems: the mixing efficiency between additives and chicken liver particles is low and easy to produce stratification, and the water content of chicken liver particles is relatively high, so caking or even blockage is likely to occur during the conveying process, as well as the dust dispersion generated during the open conveying process, and the situation of fine powder deposition caused by particle collision and crushing due to mechanical friction.

[0003] Therefore, in the prior art for the mixing process of chicken liver powder and additives, pneumatic conveying can achieve sealed and continuous conveying. However, due to the limitation of the material characteristics of chicken liver powder that is easy to absorb moisture and cake, unidirectional airflow will still cause local accumulation or pipeline wear, and it is difficult to take into account composite treatment procedures such as conveying, mixing, and drying to achieve stable feeding of chicken liver powder. Therefore, this application proposes a solution. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0030] Embodiment 1: Aiming at the problem that unidirectional air flow still causes local accumulation and it is difficult to balance the combined effects of conveying, mixing and drying, the following technical solution is proposed:

[0031] Refer to Figure 1 - Figure 8 As shown, in this embodiment, the chicken liver powder conveying system based on a multi-directional pneumatic channel includes a mixing tank 1 and an air inlet pipe 2. A lower discharge pipe 8 and a distribution tank 9 are successively installed at the lower end of the mixing tank 1, and a composite pneumatic passage component is installed at the lower end of the distribution tank 9;

[0032] The composite pneumatic passage component includes a direct blowing pipe 3, an upper branch pipe 5 and a lower branch pipe 7 that are connected to the air inlet pipe 2. A compound mixing tank 4 is installed at the end of the direct blowing pipe 3 away from the air inlet pipe 2. A feeding pipe 14 is axially installed at the other end of the compound mixing tank 4. The upper branch pipe 5 extends to the upper end of the mixing tank 1 and is successively connected to a side blowing pipe 6 and a buried blowing pipe 15;

[0033] Refer to Figure 6 - Figure 8 As shown, a longitudinal disturbance component is arranged at the inner bottom of the mixing tank 1. The longitudinal disturbance component includes a fixed bottom plate 18 that is in contact with the inner bottom of the mixing tank 1. A disturbance plate 21 is suspended in the middle of the fixed bottom plate 18. Disturbance holes 23 are opened on the outer side of the disturbance plate 21. A stirring rod 24 that extends to the middle and lower part of the fixed bottom plate 18 is installed at the inner top of the disturbance plate 21;

[0034] A distribution ring pipe 11 is embedded on the upper side of the mixing tank 1. One side of the distribution ring pipe 11 is connected to a feeding pipe 16. A discharge port 19 that is connected to the inside of the mixing tank 1 is opened on the inner side of the distribution ring pipe 11. Among them, the fixed bottom plate 18 is attached to the bottom of the mixing tank 1 and the bottom end is in an inverted trumpet-shaped structure, which can guide the mixed powder to fall into the lower discharge pipe 8 without obstruction. The specific actions include:

[0035] The disturbance plate 21 can complete a vertical reciprocating movement of longitudinal stirring in the upper and middle part of the fixed bottom plate 18, so that the mixed powder inside and outside the disturbance plate 21 can reciprocate in and out through the disturbance holes 23, and a longitudinal dispersion action can be completed with the stirring rod 24 during the vertical reciprocating movement. Another double air flow impact effect on the mixed powder is accompanied, jointly forming a mechanical comprehensive mixing action, improving the mixing efficiency of chicken liver powder and additive powder;

[0036] Refer to 1, Figure 2 andFigure 5 As shown in the figure, the axes of the intake pipe 2, the direct blowing pipe 3, the compound mixing tank 4 and the lower branch pipe 7 are on the same horizontal plane. One end of the lower branch pipe 7 far from the intake pipe 2 is vertically connected to the middle part of the compound mixing tank 4. The compound mixing tank 4 is connected to the intake pipe 2 through the lower branch pipe 7. After the mixing of the powder materials, after the direct blowing action is completed, the powder materials enter the compound mixing tank 4 to complete secondary centralized mixing, and complete secondary dispersion and blowing drying effects in the vertically arranged intake air direction. Then, the powder materials are discharged by the conveying pipe 14 to complete the material conveying;

[0037] Refer to Figure 3 As shown in the figure, a swirling air flow tank 12 is installed through the end of the direct blowing pipe 3 close to the intake pipe 2. Two swirling air flow blocks 20 are rotatably arranged inside the swirling air flow tank 12. A pair of swirling air flow blocks 20 are in an "∞" shape and are engaged with each other. The swirling air flow blocks 20 are arranged on one of the diversion channels of the entire intake pipe 2. The main function is that after the swirling air flow blocks 20 are impacted by the air flow, they can form an engaged follow-up rotation, and the air flow can make intermittent jetting actions through the gaps of the swirling air flow blocks 20 into the direct blowing pipe 3, so as to achieve intermittent jetting of the mixed powder materials and avoid problems of caking or fine powder deposition caused by mechanical friction.

[0038] Basic principle: In this embodiment, on the one hand, the conveying - mixing - drying composite effect of the chicken liver powder materials and the additive powder materials is formed by the impact effect of multi-directional conveying air flow, so as to achieve stable feeding during the pneumatic conveying of the powder materials. On the other hand, it is also combined with the longitudinal disturbance mechanism and the intermittent jetting effect to constitute the release of the limitation of the mixed powder materials being prone to moisture absorption and caking, and avoid the phenomena of local accumulation or pipeline wear; under the complementary design of the two, continuous and stable conveying can be effectively realized.

[0039] Embodiment 2: This embodiment further describes the details of the "longitudinal disturbance" stage recorded in Embodiment 1 above;

[0040] Refer to Figure 6 As shown in the figure, a distributing blade 17 is rotatably arranged inside a distributing tank 9. An electric motor 13 for driving the rotation of the distributing blade 17 is installed outside the distributing tank 9. A feeding hopper 10 is installed in the middle of the top end of the mixing tank 1. A feeding valve is arranged inside the feeding hopper 10, and an electric motor 27 is installed at the upper end of the feeding hopper 10 corresponding to the feeding valve; a rotating rod 25 threadedly connected to a disturbance disk 21 is installed at the output end of the electric motor 27. A guide rod 22 vertically slidably connected to the disturbance disk 21 is installed at the bottom side of the fixed chassis 18;

[0041] After the second motor 27 starts, it drives the rotating rod 25 to rotate. The disturbance disk 21 threadedly connected to the rotating rod 25 moves vertically under the action of the guide rod 22. Here, the selected second motor 27 is a forward and reverse motor to drive the disturbance disk 21 to move up and down reciprocally. It should be added that the first motor 13 and the second motor 27 in the present invention are both fixedly connected to the main body structure, which are not shown in the drawings for the convenience of clear display;

[0042] Referring to Figure 3 and Figure 4 As shown, the lower end of the side blowing pipe 6 extends into the mixing tank 1 and is horizontally aligned with the feeding pipe 16. The lower end of the buried blowing pipe 15 extends to the middle of the mixing tank 1 and is lower than the horizontal height of the feeding pipe 16. The buried blowing pipe 15 is rotatably connected to the rotating rod 25. A dispersion cone 26 is installed outside the lower side of the rotating rod 25 corresponding to the buried blowing pipe 15. The diameter of the dispersion cone 26 gradually increases from top to bottom and the bottom diameter is larger than the inner diameter of the buried blowing pipe 15. Under the air flow splitting effect of the upper branch pipe 5, the upper branch air flows are respectively injected into the mixing tank 1 through the side blowing pipe 6 and the buried blowing pipe 15. During this process, the side blowing pipe 6 can blow the additive powder, and the buried blowing pipe 15 completes the synchronous blowing of the mixed powder.

[0043] Referring to Embodiment 1, the side blowing pipe 6 can correspondingly blow the additive powder discharged through the feeding pipe 16 and the discharge port 19, while the buried blowing pipe 15 extends into the powder layer of the mixed powder and, under the air flow dispersion effect of the dispersion cone 26, dispersedly impacts the mixed powder to both sides, thereby jointly forming a double air flow impact on the mixed powder in the mixing tank with the divergent blowing effect of the vertically conveyed central air flow and the targeted auxiliary blowing effect, improving the mixing efficiency of the mixed powder.

[0044] Embodiment 3: This embodiment combines the technical contents of Embodiment 1 and Embodiment 2, and proposes a method for conveying chicken liver powder based on a multi-directional pneumatic channel. Referring to Figure 1 - Figure 8 As shown, it includes the following steps:

[0045] Feeding stage: The Roots blower completes air flow transportation through the air inlet pipe 2. The air flow is split into three directions through the upper branch pipe 5, the lower branch pipe 7 and the direct blowing pipe 3, and chicken liver powder and additive powder are synchronously injected through the feed hopper 10 and the feeding pipe 16 respectively, and then the inlet is sealed;

[0046] Air flow transportation stage one: Under the air flow diversion effect of the upper branch pipe 5, the upper branch air flows are respectively injected into the mixing tank 1 through the side blowing pipe 6 and the buried blowing pipe 15. The side blowing pipe 6 can correspondingly blow the additive powder discharged through the feeding pipe 16 and the discharge port 19, while the buried blowing pipe 15 extends into the material layer of the mixed powder and, under the air flow dispersion effect of the dispersion cone 26, dispersedly impacts the mixed powder to both sides. Furthermore, the combined effect of the vertically centered air flow dispersion and blowing and the targeted auxiliary blowing effect together form a double air flow impact on the mixed powder in the mixing tank;

[0047] Air flow transportation stage two: After being impacted by the air flow, the swirling air flow block 20 can form a biting follow-up rotation, and the air flow can make intermittent jetting actions through the gaps of the swirling air flow block 20 into the direct blowing pipe 3, thereby achieving intermittent jetting of the mixed powder;

[0048] Air flow transportation stage three: After the mixed powder completes the direct blowing action, it enters the compound mixing tank 4 to complete secondary centralized mixing, and achieves secondary dispersion and air blowing drying effects in the vertically set air intake direction. Subsequently, it is discharged through the conveying pipe 14 to complete the material conveying;

[0049] Mechanical mixing stage: After the motor two 27 capable of positive and reverse rotation is started, it drives the rotating rod 25 to rotate. The disturbing disk 21 threadedly connected to the rotating rod 25 moves up and down reciprocally under the action of the guiding rod 22. The disturbing disk 21 can complete the longitudinal stirring action of vertical reciprocating movement in the upper middle part of the fixed bottom plate 18, enabling the mixed powder inside and outside the disturbing disk 21 to reciprocally enter and exit through the disturbing holes 23. Along with the double air flow impact effect on the mixed powder, it jointly forms a mechanical comprehensive mixing action.

[0050] In summary: On the one hand, the air flow impact effect of multi-directional transportation constitutes the conveying - mixing - drying composite effect on the chicken liver powder and additive powder, achieving smooth feeding during the pneumatic conveying of the powder. On the other hand, it also combines the longitudinal disturbance mechanism with the intermittent jetting effect to lift the limitation of the mixed powder's tendency to absorb moisture and caking, avoiding local accumulation or pipeline wear.
