Description

Technical Field

[0001] This invention relates to the field of feed machinery technology, and in particular to a multi-zone heating and preservation device that can achieve segmented temperature control. Background Technology

[0002] A feed quality maintainer is a key piece of equipment used after the feed pelleting process to rapidly cool, dry, and screen high-temperature, high-humidity pellets. The core working principle of the feed quality maintainer is counter-current cooling. High-temperature, high-humidity pellets enter from the top and settle downwards under gravity, forming a column. Simultaneously, negative pressure generated by a suction fan forces cool air from the bottom, penetrating the entire column from bottom to top. In this reverse contact process, the cool air encounters the gradually decreasing temperature of the feed, while the hot air exchanges heat most effectively with the hottest newly arrived feed, simultaneously removing moisture evaporated from the pellet surface. This ultimately achieves rapid and uniform cooling and drying, bringing the feed to a stable state.

[0003] Many heat preservation devices have weak insulation, and their internal temperature is easily affected by the ambient temperature. When steam enters, it will quickly condense into water when it encounters the cooler cylinder wall, which can easily lower the temperature inside the cylinder, resulting in a slow heating rate of the feed and an increase in the moisture content of the material. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-zone heating and preservation device that can achieve segmented temperature control.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-zone heating and preservation device capable of segmented temperature control includes a preservation device body. The preservation device body includes a chamber. Mounting ring 1 is installed on both ends of the outer wall of the chamber and on the outside of the corresponding feed inlet and discharge outlet. Mounting ring 1 is also installed on the inner side of the outer wall of the chamber and on the corresponding feed inlet and discharge outlet. A detachable heat preservation component 1 is installed on the outside of the chamber and at the discharge outlet. A detachable heat preservation component 3 is installed on the outside of the chamber and at the feed inlet. A detachable heat preservation component 2 is installed on the outer wall of the chamber and between heat preservation component 1 and heat preservation component 3. An electric heating tape component is installed inside each of heat preservation component 1, heat preservation component 2, and heat preservation component 3.

[0007] In addition, the preferred structure is that the heat insulation component one includes heat insulation cover one and heat insulation cover two, and multiple mounting holes one are equally spaced on both sides of heat insulation cover one and heat insulation cover two, and a placement cavity one is opened on the inner side of heat insulation cover one and heat insulation cover two.

[0008] In addition, the preferred structure is that the heat insulation component 2 includes heat insulation cover 3 and heat insulation cover 4, and multiple mounting holes 1 are equally spaced on both sides of heat insulation cover 3 and heat insulation cover 4, and placement cavity 2 is provided on the inner side of heat insulation cover 3 and heat insulation cover 4.

[0010] In addition, a preferred structure is that the insulation cover one has a clearance hole one for the discharge port to pass through at the discharge port, and the insulation cover five has a clearance hole two for the inlet port to pass through at the inlet port.

[0012] Furthermore, in a preferred configuration, the mounting ring one includes a partition ring, with extension rings symmetrically mounted on both sides of the partition ring, the outer diameter of which is the same as the outer diameter of the mounting ring two.

[0013] The beneficial effects of this invention are as follows:

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1-4 A multi-zone heating and preservation device capable of segmented temperature control includes a preservation device body 1, which includes a chamber 11. Mounting rings 21 are installed on both ends of the outer wall of the chamber 11, corresponding to the inlet and outlet. Mounting rings 21 are also installed on the inner side of the outer wall of the chamber 11, corresponding to the inlet and outlet. A detachable insulation component 3 is installed on the outer side of the chamber 11, near the outlet. A detachable insulation component 5 is installed on the outer side of the chamber 11, near the inlet. A detachable insulation component 4 is installed on the outer wall of the chamber 11, between insulation components 3 and 5. An electric heating tape component 7 is installed inside each of the insulation components 3, 4, and 5.

[0022] Both ends of insulation component 3 are connected to the adjacent extension ring and mounting ring 2 respectively, both ends of insulation component 4 are connected to the adjacent extension ring respectively, and both ends of insulation component 5 are connected to the adjacent extension ring and mounting ring 2 respectively by bolts.

[0023] The insulation component 3 includes an insulation cover 31 and an insulation cover 32. Both sides of the insulation cover 31 and the insulation cover 32 are provided with multiple mounting holes 1 at equal intervals, and both the insulation cover 31 and the insulation cover 32 are provided with placement cavities 1.

[0024] The second heat insulation component 4 includes a third heat insulation cover 41 and a fourth heat insulation cover 42. Both sides of the third heat insulation cover 41 and the fourth heat insulation cover 42 are provided with multiple mounting holes 1 at equal distances, and both the third heat insulation cover 41 and the fourth heat insulation cover 42 are provided with placement cavities 2.

[0025] The insulation component 35 includes insulation cover 51 and insulation cover 62. Both sides of insulation cover 51 and insulation cover 62 are provided with multiple mounting holes 1 at equal distances, and both insulation cover 51 and insulation cover 62 are provided with placement cavity 3.

[0026] The insulation cover 31 has a clearance hole 1 at the outlet for the outlet to pass through, and the insulation cover 51 has a clearance hole 2 at the inlet for the inlet to pass through.

[0027] Flexible baffles 6 are fixedly installed on both sides of the second clearance hole, both sides of the first clearance hole, both sides of the first insulation cover 31, both sides of the second insulation cover 32, both sides of the third insulation cover 41, both sides of the fourth insulation cover 42, both sides of the fifth insulation cover 51, and both sides of the sixth insulation cover 52. The flexible baffles 6 are made of high-temperature resistant material. Sealing components are embedded on both sides of the first insulation cover 31, both sides of the second insulation cover 32, both sides of the third insulation cover 41, both sides of the fourth insulation cover 42, both sides of the fifth insulation cover 51, and both sides of the sixth insulation cover 52.

[0028] Mounting ring 21 includes a partition ring, and extension rings are symmetrically mounted on both sides of the partition ring. The outer diameter of the extension rings is the same as the outer diameter of mounting ring 22.

[0029] It is worth noting that the specific structure and working principle of the heat preservation unit 1 are existing technologies that are currently publicly available on the market, so they will not be elaborated further. Furthermore, heat preservation components one, two, and three are all equipped with independent over-temperature protectors.

[0030] In this invention, the two ends of the insulation component 3 are respectively bolted to the adjacent extension ring and the mounting ring 2, the two ends of the insulation component 4 are respectively bolted to the adjacent extension ring, and the two ends of the insulation component 5 are respectively bolted to the adjacent extension ring and the mounting ring 2.

[0032] Meanwhile, by setting up the electric heating tape components of insulation component one, insulation component two, and insulation component three, the electric heating of insulation component one, insulation component two, and insulation component three can be independently controlled and monitored for temperature, and can also heat only the section that needs to be heated. When the electric heating tape in a single area fails, the other areas can still work normally.

[0033] By setting the first and second clearance holes, the physical structure of the inlet and outlet is avoided, allowing the insulation cover to be tightly wrapped around the silo without affecting the flow of materials.

[0034] Meanwhile, the flexible baffles fill gaps and enhance sealing: the flexible baffles can fill gaps between insulation covers and between insulation covers and the silo body to prevent heat leakage.

[0035] In this invention, by sequentially arranging detachable heat preservation components one, two, and three on the outside of the preservation unit, the middle part, the outlet, or the inlet of the preservation unit can be heated as needed, and the preservation unit can be subjected to segmented temperature control.
