Description

Technical Field

[0001] This utility model relates to the field of plastic alloy particle cooling and conveying technology, and more specifically, to a rapid cooling and moisture isolation conveying device for PC and PBT blend particles. Background Technology

[0002] PC and PBT blended particles are raw materials for storing, transporting, and processing plastics in semi-finished form. PC and PBT blended particles are a type of polymer material. During the production process of PC and PBT blended particles, it is necessary to cool them to prevent the freshly extruded PC and PBT blended particles from sticking together.

[0003] However, after cooling the PC and PBT blend particles, they need to be transported. During the transport process, due to the high humidity in the processing plant, the moisture in the air may cause the PC and PBT blend particles to absorb moisture again, which will affect the quality of subsequent processing. Therefore, moisture isolation transport is required in the subsequent transport process.

[0004] Therefore, a rapid cooling and moisture-isolation conveying device for PC and PBT blend particles is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rapid cooling and moisture isolation conveying device for PC and PBT blend particles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling and moisture isolation conveying device for PC and PBT blended particles, comprising a base plate, a moisture isolation conveying box disposed above the base plate, a drying box disposed at the top of the moisture isolation conveying box, an extraction pipe connected to one side surface of the drying box, an input pipe disposed on the other side surface of the drying box, a drying filter element disposed inside the drying box, a rectangular connecting frame fixedly disposed on the outside of the drying filter element, two limiting frames symmetrically disposed on the bottom wall of the drying box, the drying filter element being located between the two limiting frames, an elastic extrusion column fixed to the bottom wall of the connecting frame, a pressure sensor installed between the two limiting frames, a signal controller disposed on the outer wall of the drying box, and a buzzer disposed on the outer wall of the drying box.

[0007] Preferably, a connecting pipe is provided at the bottom end of one side surface of the moisture isolation conveying box, and a connecting pipe is provided at the top end of the other side surface of the moisture isolation conveying box. The ends of the extraction pipe and the input pipe away from the moisture isolation conveying box are respectively connected to the two connecting pipes. Multiple diversion pipes are fixedly provided at equal distances between the two connecting pipes and the moisture isolation conveying box.

[0008] Preferably, two handles are symmetrically arranged at the top of the connecting frame, and the two handles are fixedly connected to the connecting frame by bolts.

[0009] Preferably, the moisture isolation conveying box has two connecting seats symmetrically arranged at both ends, and a conveyor belt is installed between the two connecting seats. The surface of the conveyor belt is provided with hydrophobic holes.

[0010] Preferably, a connecting frame is fixedly installed on the upper surface of the base plate and on one side of the moisture isolation conveying box. A cooling pipe is installed on the top of the connecting frame. One end of the cooling pipe is closed, and the other end of the cooling pipe is connected to an L-shaped water supply pipe. The end of the water supply pipe away from the cooling pipe is fixedly inserted through the surface of the connecting frame. Several cooling nozzles are evenly arranged at the bottom of the outer wall of the cooling pipe.

[0011] Preferably, a collection groove is provided on the upper surface of the base plate, and the collection groove is located directly below the connecting frame.

[0012] Preferably, the bottom wall of the moisture isolation conveying box is provided with a drain pipe, and a valve is provided on the drain pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with the prior art, this rapid cooling and moisture isolation conveying device for PC and PBT blended particles extracts water vapor evaporated from the PC and PBT blended particles in the moisture isolation conveying box through an extraction pipe. After being filtered and dried by the drying filter element in the drying box, the water vapor is discharged into the moisture isolation conveying box through the input pipe. This structure can quickly extract water vapor from the moisture isolation conveying box while keeping the PC and PBT blended particles relatively dry during the conveying process. This achieves a moisture isolation conveying state and avoids secondary moisture absorption by the PC and PBT blended particles during the conveying process, which would affect the subsequent processing quality.

[0015] 2. Compared with the prior art, this rapid cooling and moisture isolation conveying device for PC and PBT blended particles uses an elastic extrusion column at the bottom of the connecting frame to compress a pressure sensor. When the drying filter element filters and dries water vapor in the gas, the pressure sensor will be compressed to a certain value range. At this time, the signal controller will control the buzzer to sound, thereby reminding the staff to replace the drying filter element in time to avoid affecting the effect of the drying filter element in filtering and drying water vapor.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As attached Figures 1 to 4The device shown is a rapid cooling and moisture-isolation conveying device for PC and PBT blend particles. It includes a base plate 1, a moisture-isolation conveying box 2 mounted above the base plate 1, a drain pipe 23 on the bottom wall of the moisture-isolation conveying box 2, a valve mounted on the drain pipe 23, a drying chamber 3 at the top of the moisture-isolation conveying box 2, an extraction pipe 4 connected to one side of the drying chamber 3, a gas pump mounted on the extraction pipe 4, an input pipe 5 on the other side of the drying chamber 3, a connecting pipe 6 connected to the bottom of one side of the moisture-isolation conveying box 2, and a connecting pipe 6 also connected to the top of the other side of the moisture-isolation conveying box 2. The ends of the extraction pipe 4 and the input pipe 5 furthest from the moisture-isolation conveying box 2 are respectively connected to the two connecting pipes 6, which are isolated from water. Multiple diversion pipes 7 are fixedly installed at equal distances from the conveying box 2. A drying filter element 8 is installed inside the drying box 3. A rectangular connecting frame 9 is fixedly installed on the outside of the drying filter element 8. Two handles 15 are symmetrically installed at the top of the connecting frame 9. The two handles 15 are fixedly connected to the connecting frame 9 by bolts. Two limiting frames 10 are symmetrically installed on the bottom wall of the drying box 3. The drying filter element 8 is located between the two limiting frames 10. An elastic extrusion column 11 is fixedly installed on the bottom wall of the connecting frame 9. A pressure sensor 12 is installed between the two limiting frames 10, and the elastic extrusion column 11 is located directly above the pressure sensor 12. A signal controller 14 is installed on the outer wall of the drying box 3. A buzzer 13 is installed on the outer wall of the drying box 3 and above the signal controller 14.

[0024] In operation, the device extracts water vapor from the PC and PBT blend particles in the moisture-isolated conveying box 2 via the extraction pipe 4. This vapor is then filtered and dried by the drying filter element 8 in the drying box 3 before being discharged back into the moisture-isolated conveying box 2 via the input pipe 5. This design allows for rapid extraction of water vapor from the moisture-isolated conveying box 2 while simultaneously keeping the PC and PBT blend particles relatively dry during transport via the conveyor belt 17. This achieves a moisture-isolated conveying state, preventing moisture from evaporating from the PC and PBT blend particles. Secondary moisture absorption during transportation affects the quality of subsequent processing. At the same time, when the drying filter element 8 filters and dries water vapor in the gas, the weight of the drying filter element 8 will increase. At this time, the elastic compression column 11 set at the bottom of the connecting frame 9 will squeeze the pressure sensor 12. When the pressure sensor 12 is squeezed to a certain value range, it means that the drying filter element 8 has reached saturation in adsorbing and drying water vapor. Then, the signal controller 14 will control the buzzer 13 to sound, thereby reminding the staff to replace the drying filter element 8 in time to avoid affecting the effect of the drying filter element 8 in filtering and drying water vapor.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, a connecting frame 18 is fixedly installed on the upper surface of the base plate 1 and on one side of the moisture isolation conveying box 2. A cooling pipe 19 is installed at the top of the connecting frame 18. One end of the cooling pipe 19 is closed, and the other end of the cooling pipe 19 is connected to an L-shaped water supply pipe 20. The end of the water supply pipe 20 away from the cooling pipe 19 is fixedly passed through the surface of the connecting frame 18. Several cooling nozzles 21 are evenly spaced at the bottom of the outer wall of the cooling pipe 19. Two connecting seats 16 are symmetrically arranged at both ends of the moisture isolation conveying box 2. A conveyor belt 17 is installed between the two connecting seats 16. The surface of the conveyor belt 17 is provided with drainage holes. A receiving device is provided on the upper surface of the base plate 1. The collection tank 22 is located directly below the connecting frame 18. During use, the uncooled PC and PBT blend particles can be transported to the bottom of the connecting frame 18 via the conveyor belt 17. Then, cooling water is sprayed out through the cooling nozzles 21 on the cooling pipe 19 to cool the PC and PBT blend particles transported on the conveyor belt 17. The cooling water is collected through the drain pipe 23 located below the connecting frame 18. Then, the cooled PC and PBT blend particles are transported to the moisture isolation conveying box 2 via the conveyor belt 17. At this time, the PC and PBT blend particles have residual heat, which heats and evaporates the water on the surface of the PC and PBT blend particles.

[0028] In this embodiment, the gas pump, valve, pressure sensor 12, buzzer 13, signal controller 14, etc. are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0029] The working process of this utility model is as follows: First, the uncooled PC and PBT blend particles are transported to the bottom of the connecting frame 18 via the conveyor belt 17. Then, cooling water is sprayed out by the cooling nozzle 21 on the cooling pipe 19 to cool the PC and PBT blend particles transported on the conveyor belt 17. Next, the cooled PC and PBT blend particles are transported to the moisture isolation conveyor box 2 via the conveyor belt 17. At this time, there is residual heat in the PC and PBT blend particles, which heats and evaporates the water on the surface of the PC and PBT blend particles.

[0030] Next, water vapor is extracted from the moisture isolation conveying box 2 through the extraction pipe 4. After being filtered and dried by the drying filter element 8 in the drying box 3, it is discharged into the moisture isolation conveying box 2 through the input pipe 5. This structure can quickly extract water vapor from the moisture isolation conveying box 2, and at the same time, it can keep the PC and PBT blended particles relatively dry when they are conveyed through the conveyor belt 17 in the moisture isolation conveying box 2. This achieves a moisture isolation conveying state and avoids the PC and PBT blended particles from absorbing moisture again during the conveying process, which would affect the subsequent processing quality.

[0031] Meanwhile, when the drying filter element 8 filters and dries the water vapor in the gas, the weight of the drying filter element 8 will increase. At this time, the elastic compression column 11 set at the bottom of the connecting frame 9 will squeeze the pressure sensor 12. When the pressure sensor 12 is squeezed to a certain value range, it means that the drying filter element 8 has reached saturation in adsorbing and drying water vapor. Then, the signal controller 14 will control the buzzer 13 to sound, thereby reminding the staff to replace the drying filter element 8 in time to avoid affecting the effect of the drying filter element 8 in filtering and drying water vapor. The above is the working principle of a rapid cooling and moisture isolation conveying device for PC and PBT blended particles.
