Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyclone silo cooling technology, and in particular to a new type of cyclone silo cooling device and PE wood-plastic processing equipment. Background Technology
[0002] Cyclone silos, also known as cyclone separator silos, are devices that use inertial centrifugal force to remove as many solid particles as possible from the conveying medium in an airflow, thus achieving gas-solid separation. They are frequently used in material screening and dust control.
[0003] In existing technologies, when screening materials in PE wood-plastic cyclone silos, the temperature of the material after passing through the granulator is around 180 degrees Celsius. In ordinary silos, the temperature is above 120 degrees Celsius after the first cooling stage, around 90 degrees Celsius after the second cooling stage, and around 70 degrees Celsius after the third cooling stage. Since the raw materials for PE wood-plastic granulation are wood powder, PE plastic, and other formulations mixed together, the material containing wood powder is very hot at 70 degrees Celsius after granulation. In special cases, material may accumulate in the cyclone silo, which can easily lead to blockage and fire if not detected. Moreover, the finished material, after granulation, can easily generate internal high temperatures due to the high temperature when piled up in ton bags or storage tanks, posing a fire risk. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0027] Example 1
[0028] Reference Figures 1-5 As shown, this utility model discloses a novel cyclone silo cooling device, comprising:
[0029] The silo body 1 includes a straight section silo 11 and a conical section silo 12, with the straight section silo 11 disposed on top of the conical section silo 12;
[0030] Cooling section 2 includes a straight section water-conducting shell 21 and a conical section water-conducting shell 22. The straight section water-conducting shell 21 is fitted onto the outside of the straight section hopper 11. A plurality of first partitions 213 are circumferentially arranged between the straight section water-conducting shell 21 and the shell. A first cooling cavity 216 is formed between any two adjacent first partitions 213. A first water inlet 211 is provided at the bottom of the first cooling cavity 216, and a first water outlet 212 is provided at the top of the first cooling cavity 216. The conical section water-conducting shell 22 is fitted onto the outside of the conical section hopper 12. A plurality of second partitions 223 are circumferentially arranged between the conical section water-conducting shell 22 and the conical section hopper 12. A second cooling cavity 226 is formed between any two adjacent second partitions 223. A second water inlet 221 is provided at the bottom of the second cooling cavity 226, and a second water outlet 222 is provided at the top of the second cooling cavity 226.
[0031] The silo body 1 of this utility model comprises two parts: a straight section silo 11 and a conical section silo 12. The conical section silo 12 is located at the bottom of the straight section silo 11 and is used for collecting materials, facilitating their descent. The cooling section 2 of this utility model functions to cool the entire silo body 1. Similarly, the cooling section 2 also comprises a straight section water-conducting shell 21 and a conical section water-conducting shell 22. Specifically, the straight section water-conducting shell 21 is located on the outside of the straight section silo 11. The space between the straight section water-conducting shell 21 and the straight section silo 11 is used for circulating cooling water to cool the screened materials inside the silo. As a preferred embodiment of this utility model, multiple first partitions 213 are provided between the straight section water-conducting shell 21 and the straight section silo 11, dividing the cooling space into multiple first cooling chambers 216 for convenient and uniform cooling. Similarly, the cooling structure of the conical section silo 12 is the same as that of the straight section silo 11. The conical section water-conducting outer shell 22 is set on the outside of the conical section silo 12, and is divided into multiple second cooling chambers 226 by multiple second partitions 223. As a preferred embodiment of this utility model, both the first cooling chamber 216 and the second cooling chamber 226 adopt a low-inlet, high-outlet water inlet method to ensure that the chamber is filled with cooling water, and to ensure that the circulating cooling water cools the temperature of the material in contact with the cylinder wall in a timely manner. When the material passes through the silo body 1, the circulating cooling water carries away the temperature inside the material, thereby reducing the temperature of the material.
[0032] In the actual assembly process, multiple first partitions 213 and multiple second partitions 223 are welded at equal intervals to the surfaces of the straight section water-passing shell 21 and the conical section water-passing shell 22, respectively. Then, the straight section water-passing shell 21 with the first partitions 213 is welded to the outside of the straight section hopper 11, and the conical water-passing shell with the second partitions 223 is welded to the outside of the conical section hopper 12.
[0033] This invention cools the material inside the silo body 1 by setting a straight section water-conducting shell 21 and a conical section water-conducting shell 22 on the outside of the silo body 1, respectively. This cools the material inside the silo body 1 and prevents fire caused by high temperature of the material.
[0034] Furthermore, the first cooling cavity 216 is provided with a plurality of first flow plates 214, and a first flow channel 215 is formed between any two adjacent first flow plates 214. The first cooling cavity 216 is provided with a plurality of second flow plates 224, and a second flow channel 225 is formed between any two adjacent second flow plates 224.
[0035] Specifically, by extending the circulation speed of cooling water in the first cooling chamber 216 and the second cooling chamber 226 through the first flow channel 215 and the second flow channel 225, the contact time between cooling water and the outer wall of the hopper body 1 is extended, thereby improving the cooling efficiency of the cooling water.
[0036] Furthermore, the top of the straight section hopper 11 is provided with an air outlet 5, the side wall of the straight section hopper 11 is provided with a feed inlet 3, and the bottom of the conical section hopper 12 is provided with a discharge outlet 4.
[0037] Specifically, during use, the material enters through the feed inlet 3 on the side wall, and is screened by the entire silo body 1. The heavier material is discharged from the discharge outlet 4 at the bottom, while the lighter dust particles are discharged from the air outlet 5 at the top.
[0038] Furthermore, the inner wall of the straight section hopper 11 is provided with a reinforcing plate 111, which is arranged opposite to the feed inlet 3.
[0039] Specifically, the material enters directly from the feed inlet 3 and comes into direct contact with the inner wall of the silo body 1. Prolonged friction can cause wear on the inner wall of the silo body 1. By providing a reinforcing plate 111 on the surface opposite to the feed inlet 3, the wear on the side wall of the silo body 1 can be reduced. As a preferred embodiment of this invention, the reinforcing plate 111 is detachably connected to the straight section silo 11. After the reinforcing plate 111 wears out, it is easy to replace it with a new one, avoiding affecting the use of the entire silo body 1 and ensuring production efficiency.
[0040] Furthermore, a level gauge 6 is provided on one side of the bottom of the conical section hopper 12, the level gauge 6 passing through the conical section hopper 12 and extending into the interior of the conical section hopper 12; a temperature sensor 7 is provided on the side of the bottom of the conical section hopper 12 away from the level gauge 6, the temperature sensor 7 passing through the conical section hopper 12 and extending into the interior of the conical section hopper 12.
[0041] Specifically, under normal circumstances, the material is discharged from the bottom outlet 4. If material accumulation occurs, the level gauge 6 can detect the accumulation signal in a timely manner. Similarly, the temperature sensor 7 detects the real-time temperature of the material. When the temperature of the material exceeds the set value, a feedback signal is sent to the control center. Through the signal feedback from the level gauge 6 and the temperature sensor 7, the granulator is interlocked to stop, preventing material accumulation and temperature rise that could lead to a fire.
[0042] Furthermore, as a preferred embodiment of this utility model, the level gauge 6 and the temperature sensor 7 are detachably connected to the conical section hopper 12. When the level gauge 6 and the temperature sensor 7 malfunction, they can be replaced promptly to avoid affecting the use of the entire hopper body 1 and to ensure production efficiency.

[0044] A PE wood-plastic processing equipment includes the novel cyclone silo cooling device described in Example 1.
[0045] In summary, this utility model introduces a novel cyclone silo cooling device and PE wood-plastic processing equipment. By installing a straight-section water-conducting outer shell 21 and a conical-section water-conducting outer shell 22 on the outside of the silo body 1, the straight-section silo 11 and the conical-section silo 12 are cooled respectively, thereby cooling the material inside the silo body 1 and preventing fire caused by high material temperature. Secondly, the material level gauge 6 and temperature sensor 7 detect and interlock signals to control the granulator to stop in time, preventing excessive material accumulation and fire. Finally, a reinforcing plate 111 is installed on the opposite side of the feed inlet 3 to prevent material from abrading the entire inner wall of the silo.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
