[0003] The cooking equipment usually uses a rotary valve, i.e., a star-shaped unloader, to unload the material. The structure of the rotary valve uses a rotor with several blades to load and unload the material. The rotary blades are used to convey the material, and the material exists in the space between the blades.

In addition, the blades of the unloading device are prone to material sticking, which makes the unloading incomplete. Furthermore, the sealing surface area of the unloading device with this structure is small, the sealing performance is poor, and gas leakage is likely to occur, which increases energy consumption, requires a large amount of steam to be injected into the cooking equipment, and reduces the actual utilization rate of steam. The leaked steam wastes resources and affects the workshop environment. SUMMARY

[0028] Referring to Figures 1-5 The present application discloses a discharging device, which is particularly applied to a cooking device and is used for discharging solid materials with certain adhesion, such as bean products and wheat, and can maintain a high-temperature, high-humidity and high-pressure environment in the cooking bin during the discharging process.

[0029] Embodiment One

[0030] With reference to Figure 1 , in this embodiment, the discharging device comprises a shell 1 and a rotating mechanism 2 connected in the shell 1, which is connected with the discharging bin 3 of the cooking equipment and the receiving bin 4 receiving the discharged material through the shell 1 respectively, and the discharging process is completed through the rotating mechanism 2.

[0031] With reference to Figure 1 , the shell 1 comprises a shell body 101, which is usually provided as a regular cylinder. For the convenience of understanding, the four ends of the shell body 101 are respectively marked as a first end 111, a second end 112, a third end 113 and a fourth end 114, wherein the first end 111 and the second end 112 are oppositely arranged, and the third end 113 and the fourth end 114 are oppositely arranged. The material inlet 102 communicating with the inside of the shell body 101 is connected to the first end 111 of the shell body 101, and the material outlet 103 communicating with the inside of the shell body 101 is connected to the second end 112 of the shell body 101. The material inlet 102 is connected to the discharging bin 3 of the cooking equipment to receive the material discharged from the discharging bin 3, and the material outlet 103 is used to be connected with the receiving bin 4 to discharge the received material to the receiving bin 4.

[0032] In combination with Figure 2 , Figure 4 , the rotating mechanism 2 is arranged in the shell 1, and the rotating mechanism 2 comprises a rotating body 201 and a first rotating shaft 202 and a second rotating shaft 203 fixedly connected to the two side ends of the rotating body 201. The rotating body 201 and the shell body 101 are matched in shape and are provided as a cylinder. The first rotating shaft 202 is arranged through the third end 113 of the shell body 101, and is connected with a driving mechanism through the first rotating shaft 202. The first rotating shaft 202 is driven to rotate by the driving mechanism, thereby driving the rotating body 201 and the second rotating shaft 203 to rotate. Correspondingly, the third end 113 of the shell body 101 is provided with a third connecting end 204, and the fourth end 114 is provided with a fourth connecting end 205. The third connecting end 204 protrudes from the surface of the third end 113, and the fourth connecting end 205 protrudes from the surface of the fourth end 114. The third connecting end 204 is provided with a connecting hole matched with the outer diameter of the first rotating shaft 202, and the first rotating shaft 202 is arranged through the connecting hole and connected to the third connecting end 204 through a bearing 206. The port of the fourth connecting end 205 is connected with an end cover 207, and the second rotating shaft 203 is connected to the end cover 207 through the bearing 206. Through the above structure, the rotating mechanism 2 is connected to the shell body 101. In this embodiment, the first rotating shaft 202 and the second rotating shaft 203 are respectively connected with a shaft seal 208, and the sealing effect of the shaft seal 208 can ensure the sealing state of the shell 1.

[0033] The rotating body 201 has a through hole, with a first hole 209 and a second hole 210 at its two ends. Rotation of the rotating body 201 allows the first hole 209 and the second hole 210 to correspond to the material inlet 102 or material outlet 103 of the shell body 101, respectively. A baffle 211 is provided inside the through hole, dividing it evenly so that the first hole 209 and the second hole 210 each form a receiving cavity of equal capacity. This even division ensures the balance of the rotating body 201 and achieves accurate unloading and metering. To ensure the stability of the baffle 211, it is preferably integrally formed and connected to the rotating body 201.

[0034] When the first orifice 209 corresponds to the material inlet 102 of the shell body 101, the second orifice 210 corresponds to the material outlet 103 of the shell body 101. At this time, the first orifice 209 receives the material in the discharge bin 3. After quantitative reception, the drive mechanism is started, driving the rotating body 201 to rotate relative to and attached to the inner wall of the shell body 101. When the first orifice 209 gradually corresponds to the material outlet 103, the material in the first orifice 209 can be discharged into the feed bin 4. At this time, the second orifice 210 corresponds to the material inlet 102 to receive the material, and so on in a cycle.

[0035] Example 2

[0036] In this embodiment, the unloading device also includes a sealing mechanism 5 connected to the rotating mechanism 2. The rotating mechanism 2 and the sealing mechanism 5 work together to achieve a sealed unloading process, ensuring that the predetermined working environment within the discharge hopper 3 of the cooking equipment can be maintained.

[0037] Combination Figure 3 , Figure 4 In this embodiment, the baffle plate 211 has a hole at its center. The sealing mechanism 5 includes a piston connected within the through hole. The piston further includes a first piston 501 and a second piston 502 connected by a piston rod 503. The first piston 501, piston rod 503, and second piston 502 are combined to form an approximate "I" shape. The piston rod 503 passes through the hole, and the first piston 501 and second piston 502 are respectively disposed in two accommodating cavities. In this embodiment, the sealing mechanism 5 also includes a bushing 504. The piston rod 503 is connected to the hole through the bushing 504. The first piston 501 is slidably connected to the inner wall of the first hole 209, and the second piston 502 is slidably connected to the inner wall of the second hole 210. When an external force is applied to the first piston 501 or the second piston 502, the first piston 501 or the second piston 502 can move synchronously under the cooperation of the piston rod 503 and the bushing 504.

[0038] The end surface of the first piston 501 and the second piston 502 should match the shape of the accommodating cavity formed on the surface of the rotating body 201, and the length of the piston connecting rod 503 is approximately equal to the sum of the depth of the accommodating cavity and the thickness of the baffle plate 211, that is, the movement stroke of the first piston 501 is within the depth range of the first hole body 209, and the movement stroke of the second piston 502 is within the depth range of the second hole body 210. When the first piston 501 moves to the bottom of the first hole body 209, the second piston 502 correspondingly moves to the top of the second hole body 210 and seals the second hole body 210, and when the first piston 501 moves to the top of the first hole body 209, the first hole body 209 can be sealed, and at this time, the second piston 502 correspondingly moves to the bottom of the second hole body 210. Preferably, the sealing mechanism 5 further comprises two sets of sealing members 505, which are used to improve the sealing performance of the piston member. The sealing member 505 is preferably a sealing ring, and the first piston 501 and the second piston 502 are sleeved with the sealing ring, which can further ensure the sealing between the first piston 501, the second piston 502 and the inner wall of the accommodating cavity, and the sealing ring can also scrape off the material adhered to the inner wall of the first hole body 209 or the second hole body 210.

[0039] In order to prevent the gap between the rotating body 201 and the shell body 101 from generating air flow, in the embodiment, the sealing mechanism 5 further comprises a sealing part 507 connected between the rotating body 201 and the shell body 101, and the sealing part 507 comprises a circular sealing part connected to the two ends of the shell body 101 respectively and a strip-shaped sealing part connected along the length direction of the shell body 101. The sealing part 507 can block the air flow between the rotating body 201 and the shell body 101.

[0040] The baffle plate 211 is provided with a gas guide hole 506 which is communicated with the first hole body 209 and the second hole body 210. The gas guide hole 506 can prevent the piston member from moving unsmoothly due to gas stagnation.

[0041] In the embodiment, the movement of the piston member is affected by the gravity G1 of the material in the discharge bin 3 under the material level, the gravity G2 of the piston assembly, the pressure difference ΔP between the discharge bin 3 and the feeding bin 4, and the resistance F of the first piston 501 and the second piston 502 (the friction between the first piston 501 and the second piston 502 and the inner wall of the accommodating cavity, the friction between the piston connecting rod 503 and the shaft sleeve 504, and the resistance of the material when the lower piston discharges). When G1+G2+ΔP*S (cross-sectional area of the piston) > F (ΔP=P1-P2, P1 and P2 are the pressures in the discharge bin 3 and the feeding bin 4 respectively), the piston member is automatically in the low position under the driving of the rotating body 201, the first piston 501 completes the feeding, and the second piston 502 completes the discharging.

[0042] Referring to Figure 5When the discharging device is in the (one) position, the piston member is in the vertical position, and the piston member is automatically in the low position, completing the feeding of the first piston 501 and the discharging of the second piston 502.

[0043] When the discharging device is in the (two) position, the feeding and discharging are completed, and the sealing area is entered.

[0044] When the discharging device is in the (three) position, the first hole body 209 enters the sealing area with the material, and the discharge bin 3 and the feeding bin 4 are sealed and isolated by the action of the piston member, preventing the flow of gas (vapor) between the discharge bin 3 and the feeding bin 4.

[0045] When the discharging device is in the (four) position, the first piston 501 enters the discharging area, and the first hole body 209 filled with material starts to discharge, and the empty second hole body 210 starts to feed, that is, the first piston 501 discharges, and the second piston 502 feeds.

[0046] When the discharging device is in the (one) position again, the piston member is in the vertical position, and the piston member is automatically in the low position, completing the feeding of the first piston 501 and the discharging of the second piston 502.

[0047] The above actions are repeated to continuously transport the granular material from the discharge bin 3 to the feeding bin 4.

[0048] In this embodiment, by setting the sealing mechanism 5 and the piston member contained therein, sealing and discharging can be achieved, the predetermined environment in the discharge bin 3 can be effectively maintained, gas leakage can be reduced, and energy consumption can be reduced; the self-cleaning effect of the piston can also prevent material sticking, making the discharging measurement more accurate.

[0049] Example Three

[0050] In combination Figure 2 In this embodiment, the rotating body 201 has a predetermined length, the through holes and the sealing mechanism 5 are arranged in multiple groups, distributed along the length direction of the rotating body 201, and the multiple groups of through holes are uniformly arranged along the circumferential direction of the rotating body 201. The arrangement of multiple groups of through holes and sealing mechanisms 5 can further improve the discharging speed. The number of through holes and sealing mechanisms 5 is preferably 1-9 groups.

[0051] In the continuous cooking equipment with high pressure, high humidity and high temperature, the discharging device can effectively discharge the cooked material from the cooking equipment while maintaining the high pressure, high humidity and high temperature sealing environment in the cooking equipment. The device can effectively reduce gas leakage, form self-cleaning through the piston, prevent problems such as material sticking, incomplete discharging, inaccurate metering and difficult cleaning, etc. Through tests and production verification, the present application can realize continuous operation, accurate feeding metering, and compared with the traditional star-shaped discharger, the present discharging device can reduce steam loss by more than 20%.

[0052] It can be understood that the discharging device provided by the present application is not limited to be applied in the cooking equipment, but also can be applied to the solid material discharging in other fields. The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application, and are not used to limit the present application.
