Description

Technical Field

[0001] This utility model relates to the field of PE wood-plastic processing technology, and in particular to a cooling silo device. Background Technology

[0002] In the granulation process of wood-plastic composites (WPC), the wood-plastic mixture reaches a high temperature (typically around 180℃) after extrusion through the granulator, requiring cooling and collection via multi-stage cyclone silos. Currently, the industry commonly uses traditional cyclone silos, which are ordinary cylindrical designs with a diameter of approximately 1 meter and a height of approximately 3 meters. These silos lack targeted cooling functions and cleaning structures. Furthermore, WPC formulations contain up to 60% wood flour and include easily adherent components such as paraffin wax and lubricants.

[0003] Therefore, existing cyclone silos have the following defects in actual operation: The surface temperature of the high-temperature granulated material still exceeds 120°C when it enters the first-stage cyclone silo. Small molecules such as paraffin and lubricants contained within it easily volatilize at high temperatures and condense on the inner wall of the silo, forming a viscous layer. This layer accumulates continuously, not only reducing the effective volume of the silo and affecting material flow, but also, due to its high content of flammable components (such as wood flour and wax), easily causing combustion accidents when encountering sparks or localized high temperatures carried during the granulation process. Furthermore, ordinary cyclone silos cool the material coming out of the granulator slowly, and the material remains highly stable even after cooling in the cyclone silo. When the material is piled in the ton bag, the temperature of the material in the middle of the ton bag cannot dissipate, easily leading to the risk of spontaneous combustion. The material formulation contains a high proportion of wood flour, and the silo inlet is also very prone to wear. In summary, existing ordinary cyclone silos have defects such as insufficient cooling capacity, easy material accumulation on the walls, and inconvenient cleaning when dealing with high-wood-flour, high-viscosity WPC materials.

[0021] 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.

[0022] Reference Figures 1 to 3 As shown, this utility model discloses a cooling silo device, including a frame 1; The cooling silo unit further includes a silo unit, which includes a silo body 2, an inlet 21, and an outlet 22. The inlet 21 is used for material to enter the silo body 2, and the outlet 22 is used for the material to exit the silo body 2. The inlet 21 is a standard part that is easy to replace, facilitating future maintenance and replacement.

[0024] Preferably, the first coolant is water.

[0025] Furthermore, the cooling silo device also includes a cooling unit, which includes a cooling pipe 30. The cooling pipe 30 is arranged within the accommodating space, so that the cooling pipe 30 is in contact with the first coolant and is immersed in the first coolant.

It can cool WPE wood granulation materials. The silo body adopts a double-layer structure, which includes an inner layer and an outer layer spaced apart along the thickness direction of the silo sidewall. Cooling liquid flows into the receiving space formed between the inner and outer layers. In addition, cooling pipes are arranged in the receiving space, and a second coolant flows through the cooling pipes. The cooling pipes remove the heat of the first coolant between the inner and outer layers to achieve a cooling effect. The temperature measuring device detects the temperature inside the silo body. When the temperature exceeds the preset temperature, an alarm is issued in time.

[0034] The cooling unit also includes an inlet pipe 31, an inlet ball valve 32, a return pipe 33, and a return ball valve 34; specifically, the liquid inlet of the cooling pipe 30 is connected to the inlet pipe 31, and the liquid outlet of the cooling pipe 30 is connected to the return pipe 33; the inlet ball valve 32 is installed on the inlet pipe 31, and the return ball valve 34 is installed on the return pipe 33.

[0036] The hopper unit also includes at least one vibrating hammer 5, which is disposed on the top of the hopper body 2, so as to periodically vibrate and knock the top of the hopper body 2 to cause the attached material adhering to the top of the hopper body 2 to fall off.

[0037] The silo unit also includes a level gauge 6, which is installed on the silo body 2 to detect the material position inside the silo body 2. The level gauge 6 is communicatively connected to the control unit, so that it can upload the material position inside the silo body 2 in real time.
