Abstract
Description
Technical Field
[0001] The utility model relates to an inner door structure for water material stratification of a sterilizing kettle, belonging to the technical field of sterilizing kettles. Background Art
[0002] When the sterilizer is sterilizing the product, the product is placed in the sterilizer, and then circulating hot water is passed into the sterilizer to sterilize the product in the sterilizer.
[0003] In the existing equipment, a water tank is provided at the lower discharge port of the sterilization kettle during the entire heating and sterilization process. In order to prevent the lower discharge port of the lower sterilization kettle from being located below the water surface, a part of the water in the water tank needs to be discharged during the heating and sterilization process, so that the heat in the hot sterilization kettle will not be transferred to the cold water in the water tank, thereby preventing the heat loss in the sterilization kettle, which will cause unqualified sterilization; but when the cooling is completed and the material is discharged, the water needs to cover the lower discharge port, so that negative pressure will be formed in the kettle, so that the material can be discharged slowly. This operation requires continuous drainage and water replenishment of the water tank, and requires the construction of a sufficiently large water tank, which is time-consuming and labor-intensive and causes relatively large energy consumption.
[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] In view of the deficiencies in the background technology, the utility model provides an inner door structure for stratifying water and material in a sterilizing kettle, which can prevent the material from contacting the water in the water receiving trough during the heating process, and will not cause heat loss in the inner cylinder. At the same time, there is no need to change the water level in the water receiving trough, thus eliminating the process of water filling and draining the water receiving trough, thereby improving work efficiency and avoiding heat loss.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0007] The invention discloses an inner door structure for layering water and material of a sterilizing kettle, comprising an inner cylinder and an outer cylinder sleeved on the outer side of the inner cylinder, wherein an inner cylinder discharge port and an outer cylinder discharge port are respectively arranged at the lower ends of the inner cylinder and the outer cylinder, and an annular water flow channel is formed between the outer cylinder and the inner cylinder, and an inner door assembly is arranged at the inner cylinder discharge port, wherein the inner door assembly is located inside the outer cylinder and directly above the outer cylinder discharge port, and the inner door assembly and the outer cylinder discharge port are arranged at a certain distance.

[0009] An upper blocking door is arranged between the two guide shafts. A plurality of water leakage holes are arranged on the upper blocking door. Sliding sleeves are fixed at both ends of the upper blocking door. The sliding sleeves are slidably mounted on the guide shafts.
[0010] Furthermore, the lower end of the inner cylinder is in a tapered shape, so that the diameter of the inner cylinder outlet is smaller than the inner diameter of the outer cylinder.
[0011] Furthermore, there are two upper blocking doors, each of which completely blocks the inner cylinder discharge port when combined, and each of which blocks half of the inner cylinder discharge port, and when the two are separated, the inner cylinder discharge port is opened.
[0012] Furthermore, a lead screw is provided at the upper end of one of the guide shafts, and the lead screw is arranged parallel to the guide shaft. The front half of the lead screw is a positive thread, and the rear half is a negative thread.

[0014] Furthermore, an outer cylinder discharge port of the outer cylinder is provided with an outer door assembly.

[0025] like Figure 1-3 As shown, the utility model provides an inner door structure for water-material stratification of a sterilizing kettle, comprising an inner cylinder 1 and an outer cylinder 2 sleeved on the outside of the inner cylinder 1, an inner cylinder discharge port and an outer cylinder discharge port are respectively provided at the lower ends of the inner cylinder 1 and the outer cylinder 2, an annular water flow channel is formed between the outer cylinder 2 and the inner cylinder 1, an inner door assembly is provided at the inner cylinder discharge port, the inner door assembly is located inside the outer cylinder 2, the inner door assembly is directly above the outer cylinder discharge port, and the inner door assembly and the outer cylinder discharge port are arranged at a certain distance.
[0026] The inner door assembly includes two parallel guide shafts 4 arranged at a certain distance, and a first fixing sleeve 3 is provided at both ends of each guide shaft 4. The first fixing sleeve 3 is axially and horizontally fixed on the wall of the outer cylinder 2, and the two ends of the guide shaft 4 are fixed on the first fixing sleeve 3, and the axes of the two guide shafts 4 are arranged horizontally;
[0027] An upper blocking door 5 is provided between the two guide shafts 4, and a plurality of water leakage holes are arranged on the upper blocking door 5. Sliding sleeves 6 are fixed at both ends of the upper blocking door 5, and the sliding sleeves 6 are slidably mounted on the guide shafts 4. When the upper blocking door 5 blocks the inner cylinder discharge port, the material in the inner cylinder 1 can be blocked. When the upper blocking door 5 slides away from the inner cylinder discharge port, the material flows out from the inner cylinder discharge port and falls into the outer cylinder discharge port.
[0028] The lower end of the inner cylinder 1 is a tapered cone, so that the diameter of the inner cylinder outlet is smaller than the inner diameter of the outer cylinder 2. When the upper barrier door 5 slides away from the inner cylinder outlet, the upper barrier door 5 is located in the space between the inner cylinder outlet and the inner cavity of the outer cylinder 2.
[0029] Furthermore, there are two upper blocking doors 5, each of which completely blocks the inner cylinder discharge port when combined, and each of which blocks half of the inner cylinder discharge port, and when the two are separated, the inner cylinder discharge port is opened.
[0030] A lead screw 7 is provided at the upper end of one of the guide shafts 4, and the lead screw 7 is arranged parallel to the guide shaft 4. The front half of the lead screw 7 is a positive thread, and the rear half is a negative thread. A driving nut 9 is respectively installed on the front half and the rear half. Each of the driving nuts 9 is fixedly connected to the sliding sleeve 6 at the corresponding end through a connecting plate 10. When the lead screw 7 rotates to drive the two driving nuts 9 to separate and approach each other, the driving nut 9 drives the two sliding sleeves 6 on the lower side to separate and close each other through the connecting plate 10.
[0031] A second fixing sleeve 8 is respectively provided at both ends of the lead screw 7. The two second fixing sleeves 8 are respectively fixedly mounted on the cylinder wall of the outer cylinder 2. The lead screw 7 is rotatably mounted in the second fixing sleeve 8.

[0032] The outer barrel discharge port of the outer barrel 2 is provided with an outer door assembly 11, and the sterilizing kettle has double doors, so that the materials after sterilization can be temporarily stored between the outer barrel discharge port and the inner barrel discharge port.
[0033] The specific working principle of the utility model:
[0034] When the sterilization operation is performed using the sterilization kettle of the present device, a water receiving trough is provided at the lower end of the sterilization kettle, and the material is placed in the inner cylinder 1. During the sterilization process, the inner door assembly is in a closed state, and the material is blocked within the inner cylinder discharge port. At this time, hot water is introduced into the inner cylinder 1 and the annular water flow channel between the inner cylinder 1 and the outer cylinder 2 to sterilize the material in the inner cylinder 1 with high-temperature hot water. Since the outer cylinder discharge port is close to the water surface of the water receiving trough, the material is above the inner door assembly. During the heating process, the material does not contact the water in the water receiving trough, and the heat in the inner cylinder 1 will not be lost. At the same time, there is no need to change the water level in the water receiving trough, which eliminates the process of water filling and draining the water receiving trough, improves work efficiency, and avoids heat loss.
[0035] The inner door assembly includes two upper blocking doors 5 driven by motors. The two upper blocking doors 5 move horizontally instead of flipping. During the discharge process, the materials will not affect the opening of the upper blocking door 5 during translation, and the opening is smoother. In addition, the inner door assembly is arranged between the inner cylinder discharge port and the outer cylinder 2, and the internal gap is reasonably utilized. The inner door assembly is inside the outer cylinder 2 and is not affected by external interference.
[0036] An outer door assembly 11 is provided at the outer barrel discharge port, so that the sterilizer has double doors. The materials after sterilization can be temporarily stored between the outer barrel discharge port and the inner barrel discharge port. The material sterilization of the upper inner door assembly does not affect the material discharge, and they do not affect each other.
[0037] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
