Description

Technical Field

[0001] The invention relates to the technical field of pneumatic conveying, and in particular 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 steps such as cleaning, crushing, mixing, drying, and pulverizing. The mixing process of additives and chicken liver powder is carried out synchronously through a conveying system. Traditional conveying systems mostly use mechanical spiral conveying or open pipelines, which have the following problems: the mixing efficiency between additives and chicken liver particles is low and prone to stratification, and the chicken liver particles have a high moisture content, which easily leads to agglomeration or even blockage during the conveying process, as well as dust dispersion generated by the open conveying process, and mechanical friction causes particle collision and crushing, resulting in fine powder deposition.

[0003] Therefore, in the prior art, pneumatic conveying is used to achieve closed and continuous conveying for the mixing process of chicken liver powder and additives. However, due to the material characteristics of chicken liver powder that it is easy to absorb moisture and agglomerate, the unidirectional airflow will still cause local accumulation or pipe wear, and it is difficult to take into account the complex processing procedures such as conveying, mixing and drying to achieve smooth feeding of chicken liver powder. For this purpose, this application proposes a solution. Summary of the Invention

DETAILED DESCRIPTION

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all 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.

[0030] Example 1: To address the problem that unidirectional airflow still causes local accumulation and is difficult to achieve the combined effects of conveying, mixing and drying, the following technical solution is proposed:

[0031] Reference Figure 1 - Figure 8 As shown, the chicken liver powder conveying system based on the multi-directional pneumatic channel in this embodiment includes a mixing tank 1 and an air inlet pipe 2. The lower end of the mixing tank 1 is sequentially installed with a lower discharge pipe 8 and a distribution tank 9, and the lower end of the distribution tank 9 is installed with a composite pneumatic passage assembly;

[0032] The composite pneumatic passage assembly includes a straight blowing pipe 3, an upper branch pipe 5, and a lower branch pipe 7 connected to the air inlet pipe 2. The end of the straight blowing pipe 3 away from the air inlet pipe 2 is installed with a compound mixing tank 4. The other end of the compound mixing tank 4 is axially installed with a feed pipe 14. The upper branch pipe 5 extends to the upper end of the mixing tank 1 and is sequentially connected with a side blowing pipe 6 and a buried blowing pipe 15.

[0033] Reference Figure 6 - Figure 8 As shown, the inner bottom of the mixing tank 1 is provided with a longitudinal disturbance assembly, which includes a fixed bottom plate 18 connected to the inner bottom of the mixing tank 1, a disturbance plate 21 suspended in the middle of the fixed bottom plate 18, a disturbance hole 23 is opened on the outer side of the disturbance plate 21, and a stirring rod 24 extending to the lower middle part of the fixed bottom plate 18 is installed on the inner top of the disturbance plate 21;

[0034] A material distribution ring pipe 11 is embedded on the upper side of the mixing tank 1. A feeding pipe 16 is connected to one side of the material distribution ring pipe 11. A material outlet 19 communicating with the interior of the mixing tank 1 is opened on the inner side of the material distribution ring pipe 11. The fixed base plate 18 is fitted on the bottom of the mixing tank 1 and has an inverted trumpet-shaped structure at the bottom end, which can guide the mixed powder to fall unimpeded into the lower discharge pipe 8. The specific actions include:

[0035] The disturbance disk 21 can complete a longitudinal stirring action of vertical reciprocating movement in the middle and upper part of the fixed base 18, so that the mixed powder inside and outside the disturbance disk 21 can complete a reciprocating in and out through the disturbance hole 23. In addition, the stirring rod 24 can complete a longitudinal stirring action during the vertical reciprocating movement. In addition, the dual airflow impact effect on the mixed powder forms a mechanical comprehensive mixing action, thereby improving the mixing efficiency of the chicken liver powder and the additive powder.

[0036] Reference 1. Figure 2 and Figure 5 As shown, the axes of the air inlet pipe 2, the direct blowing pipe 3, the compounding tank 4 and the lower branch pipe 7 are in the same horizontal plane, and the end of the lower branch pipe 7 away from the air inlet pipe 2 is vertically connected to the middle of the compounding tank 4, wherein the compounding tank 4 is connected to the air inlet pipe 2 through the lower branch pipe 7. After the mixed powder completes the direct blowing action, it enters the compounding tank 4 to complete the secondary centralized mixing, and completes the secondary stirring and blowing drying effect in the vertically arranged air inlet direction, and is then discharged from the feed pipe 14 to complete the feed.

[0037] Reference Figure 3 As shown, a cyclone flow tank 12 is installed through one end of the straight blowing pipe 3 close to the air inlet pipe 2, and two cyclone flow blocks 20 are arranged to rotate inside the cyclone flow tank 12. A pair of cyclone flow blocks 20 are in an "∞" shape and are arranged to interlock with each other. The cyclone flow block 20 is arranged on one of the branch channels of the entire air inlet pipe 2. The main function is to form an interlocking follow-up rotation after the cyclone flow block 20 is impacted by the airflow, and the airflow can make intermittent spraying actions into the straight blowing pipe 3 through the gaps of the cyclone flow blocks 20, thereby achieving intermittent spraying of the mixed powder, avoiding the problem of agglomeration or fine powder deposition caused by mechanical friction.

[0038] Basic principle: In this embodiment, on the one hand, the air flow impact effect of multi-directional conveying is used to form a composite effect of conveying, mixing and drying of chicken liver powder and additive powder, thereby achieving smooth feeding during the pneumatic conveying of the powder. On the other hand, the longitudinal disturbance mechanism is combined with the intermittent spraying effect to remove the restriction on the easy moisture absorption and agglomeration of the mixed powder, thereby avoiding local accumulation or pipeline wear. Under the complementary design of the two, continuous and stable conveying can be effectively achieved.

[0039] Example 2: This example further describes the "longitudinal disturbance" stage described in Example 1 above in detail;

[0040] Reference Figure 6 As shown, the internal rotating distribution tank 9 is provided with a distribution blade 17, the external distribution tank 9 is provided with a motor 13 for driving the distribution blade 17 to rotate, the top middle part of the mixing tank 1 is provided with a feed hopper 10, the feed hopper 10 is provided with a feed valve, and the upper end of the feed hopper 10 corresponding to the feed valve is provided with a motor 27; the output end of the motor 27 is provided with a rotating rod 25 threadedly connected to the disturbance disk 21, and the bottom side of the fixed base 18 is provided with a guide rod 22 vertically slidably connected to the disturbance disk 21;

[0041] After the motor 27 is started, the rotating rod 25 is driven to rotate, and the disturbance plate 21 threadedly connected to the rotating rod 25 moves vertically under the action of the guide rod 22. Here, the motor 27 is a forward and reverse motor to drive the disturbance plate 21 to move up and down. It should be noted that the motor 13 and the motor 2 27 in the present invention are fixedly connected to the main structure. For the sake of clarity, they are not drawn in the drawings.

[0042] Reference Figure 3 and Figure 4 As shown, the lower end of the side blow pipe 6 extends into the mixing tank 1 and is horizontally aligned with the feeding pipe 16, the lower end of the buried blow 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 blow pipe 15 is rotatably connected to the rotating rod 25, and a dispersion cone 26 is installed on the outside of the rotating rod 25 corresponding to the lower side of the buried blow 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 blow pipe 15. Under the air flow diversion effect of the upper branch pipe 5, the upper branch airflow is respectively injected into the mixing tank 1 through the side blow pipe 6 and the buried blow pipe 15. During this process, the side blow pipe 6 can spray the additive powder, while the buried blow pipe 15 completes the synchronous blowing of the mixed powder.

[0043] Referring to Example 1, the side blowing pipe 6 can blow the additive powder discharged through the feeding pipe 16 and the discharge port 19 accordingly, while the buried blowing pipe 15 extends into the material layer of the mixed powder and completes the divergent impact of the mixed powder to both sides under the airflow dispersion effect of the dispersion cone 26, and then the divergent blowing effect of the vertical airflow transported in the center is combined with the targeted auxiliary blowing effect to form a double airflow impact on the mixed powder in the mixing tank, thereby improving the mixing efficiency of the mixed powder.

[0044] Example 3: This example combines the technical content of Example 1 and Example 2 to propose a chicken liver powder delivery method based on a multi-directional pneumatic channel. Figure 1 - Figure 8 As shown, the following steps are included:

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

[0046] Airflow conveying stage 1: Under the airflow diversion effect of the upper branch pipe 5, the upper branch airflow is 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 blow the additive powder discharged through the feeding pipe 16 and the discharge port 19 accordingly, while the buried blowing pipe 15 extends into the material layer of the mixed powder and, under the airflow dispersion effect of the dispersion cone 26, the mixed powder is diverged to both sides. Then, the divergent spraying effect of the vertical airflow transported in the center and the targeted auxiliary blowing effect form a double airflow impact on the mixed powder in the mixing tank;

[0047] Airflow conveying stage 2: After being impacted by the airflow, the cyclone flow block 20 can form an interlocking follow-up rotation, and the airflow can make an intermittent spraying action into the straight blowing pipe 3 through the gap of the cyclone flow block 20, thereby achieving intermittent spraying of the mixed powder;

[0048] Air flow conveying stage 3: After the mixed powder has completed the direct blowing action, it enters the compounding tank 4 for secondary centralized mixing, and completes the secondary stirring and blowing drying effect in the vertical air inlet direction, and is then discharged from the conveying pipe 14 to complete the conveying;

[0049] Mechanical mixing stage: After the motor 27 that can rotate forward and reverse is started, it drives the rotating rod 25 to rotate, and the disturbance disk 21 threadedly connected to the rotating rod 25 moves back and forth up and down under the action of the guide rod 22. The disturbance disk 21 can complete a vertical reciprocating longitudinal stirring action in the middle and upper part of the fixed base 18, so that the mixed powder inside and outside the disturbance disk 21 can complete a reciprocating in and out of the disturbance hole 23, accompanied by a double airflow impact effect on the mixed powder, together forming a mechanical comprehensive mixing action.

[0050] In summary: on the one hand, the impact effect of the airflow through multi-directional conveying constitutes a composite effect of conveying, mixing and drying of the chicken liver powder and the additive powder, thereby achieving smooth feeding during the pneumatic conveying of the powder; on the other hand, the longitudinal disturbance mechanism is combined with the intermittent spraying effect to remove the restriction on the easy moisture absorption and agglomeration of the mixed powder, thereby avoiding local accumulation or pipeline wear.
