Technical Field
[0001] The utility model relates to the field of feeding and dust removal, in particular to an automatic feeding and dust removal device for a crystallization dryer. Background Art
[0002] Currently, an infrared dryer generally consists of a base frame, a drum, a heating irradiation box, a feeding assembly, and a sliding machine frame seat equipped with a lamp holder. The feeding assembly feeds materials into the drum. As the drum rotates, the materials can be evenly tumbled. Meanwhile, the infrared radiation tubes installed on the irradiation box irradiate and heat the materials, causing the materials to crystallize or dry. The inclined baffle or spiral blade arranged inside the drum is conveyed to the outlet at the discharge end of the drum while the drum rotates, completing the process of continuous infrared crystallization drying or drying. In actual use, since most users need to frequently change the materials or models to be processed, in order to avoid cross-contamination between different materials, it is necessary to clean thoroughly each time to maintain the purity of different materials in each batch. The traditional solution is to directly pour or use a conveyor belt to send the target materials into the storage hopper, and then start the crystallization drying or drying work. However, the current technology still has the following disadvantages: 1. The inside of the barrel is contaminated by dust and is difficult to clean. There is a certain proportion of tiny dust particles in the materials. After entering the crystallization dryer, especially due to the friction between the materials, the fine dust adheres to various positions and is extremely difficult to clean thoroughly, contaminating the target materials in the next batch; 2. Due to the disturbance of the dust in the barrel for tumbling and blowing, it is easy to be lifted and contact the high-temperature position. The surface of the infrared lamp tube can reach 500 - 900 °C. If resin powder chips contact the surface of the lamp tube, they will quickly melt and adhere, quickly coke, and even smoke or catch fire, further causing coking pollution or safety accidents; 3. When processing objects such as soybeans and nut seeds, the adhesion of carbohydrate powder chips is more likely to cause carbonization, ignition, and even dust explosion.

[0025] The following is a further detailed description through specific embodiments:
[0026] The reference numerals in the accompanying drawings of the specification include: first dust collection box 1, dust collector 2, cyclone separation cylinder 3, second dust collection box 4, material frame 200, vacuum hopper 5, storage hopper 8, fan 9, negative pressure pipeline 201, material suction pipeline 202, hopper pipe 203, glass pipe 108, leakage pipe 103, gate 107, material level sensor 105, hopper base 7, dust cylinder 130, cone 125, base 124, discharge channel 213, eccentric feed port 210, drawer box 127, handle 128, filter screen 102, knob bolt 122.
[0027] As shown in the Figure 1-2 accompanying drawings, this embodiment shows an automatic feeding and dust removal device for a crystallization dryer, including a first dust collection box 1, a dust collector 2, a cyclone separation cylinder 3, a second dust collection box 4, a material frame 200, a vacuum hopper 5, a storage hopper 8 and a fan 9. The dust collector 2 is arranged above the first dust collection box 1. A negative pressure pipeline 201 is connected between the dust collector 2 and the material frame 200. A material suction pipeline 202 is connected between the dust collector 2 and the vacuum hopper 5. The vacuum hopper 5 is arranged above the storage hopper 8. A hopper pipe 203 is connected between the vacuum hopper 5 and the cyclone separation cylinder 3. The cyclone separation cylinder 3 is arranged above the second dust collection box 4. A fan pipe is connected between the cyclone separation cylinder 3 and the fan 9. A glass pipe 108 is arranged between the vacuum hopper 5 and the storage hopper 8. A leakage pipe 103 is arranged below the vacuum hopper 5. A gate 107 is arranged at the bottom of the leakage pipe 103. The vacuum hopper 5 is communicated with the glass pipe 108 through the leakage pipe 103. A material level sensor 105 is arranged on the pipe wall of the glass pipe 108. A hopper base 7 is arranged below the glass pipe 108. The top of the hopper base 7 is communicated with the glass pipe 108, and the bottom of the hopper base 7 is communicated with the storage hopper 8. A filter screen 102 is arranged on the vacuum hopper 5.
[0028] In the material box 200 of this embodiment, bulk solid substances such as plastics, peanuts, and seeds can be placed. In this case, resin particles are used as an example for illustration. The negative pressure pipeline 201 sucks resin particles from the material box 200 and enters the on-line dust collector 2. The dust collector 2 separates the resin particles and dust. The separated dust is collected downward by the first dust collection box 1. The resin particles enter the vacuum hopper 5 through the material suction pipeline 202. At this time, the vacuum hopper 5 is in a negative pressure material suction state, and the gate 107 is automatically closed due to the vacuum. The resin particles stay in the vacuum hopper 5, and the negative pressure air enters the cyclone separation barrel through the filter screen 102 and the hopper pipe 203 and is further purified. Tiny dust enters the second dust collection box 4 for collection. The clean air enters the fan 9 through the fan 9 pipe. After the fan 9 is turned off, the negative pressure inside the vacuum hopper 5 is eliminated, and the gate 107 automatically opens. The resin particles enter the glass tube 108 channel and further enter the storage hopper 8 for crystallization drying. The above process is repeated in a cycle until the resin particles are full, triggering the signal position of the level sensor 105. The fan 9 pauses until the storage hopper 8 of the crystallization dryer is further consumed and the material level drops, and then the whole cycle is automatically started, so as to keep the whole automatic feeding and dust removal work running fully automatically.
[0029] It can be understood that an automatic feeding and dust removal device is provided with a PLC controller, which is respectively connected to the level sensor 105 and the fan 9 in terms of signals. When the level sensor 105 detects that the material position has not reached the set height, the PLC controller controls the fan 9 to draw air to create a negative pressure environment for feeding materials; when the level sensor 105 detects that the material position reaches the set height, the PLC controller controls the fan 9 to stop working to stop feeding.
[0030] In this example embodiment, further, the level sensor 105 can use photoelectric, capacitance, and resistance rotation sensors to monitor the material level, or the level sensor 105 can be moved above the storage hopper 8 to achieve fully automatic dust removal and feeding in the same way.
[0031] Among them, the dust collector 2 includes a dust cylinder 130, a conical barrel 125, a base 124, and a discharge channel 213. The dust cylinder 130 is arranged on the first dust collection box 1. The base 124 is arranged inside the dust cylinder 130 and on the first dust collection box 1. The conical barrel 125 is arranged inside the dust cylinder 130 and fixed on the base 124. One end of the discharge channel 213 is connected to the conical barrel 125, and the other end of the discharge channel 213 extends out of the dust cylinder 130; the conical barrel 125 is provided with mesh holes, and a sieve mesh is covered on the mesh holes. An eccentric feeding port 210 is arranged at the top of the dust cylinder 130, and the eccentric feeding port 210 is located above the conical barrel 125.
[0032] The conical barrel 125 inside the dust collector 2 has mesh holes, and the shape of the mesh holes can be set to round holes, waist-shaped holes, long strip holes, etc. according to different target materials and the standard of powder debris to be removed. The specific size of the holes can be flexibly replaced and adjusted according to the special requirements for removing powder debris.
[0033] In this embodiment, as Figure 2 shown, the working process of the dust collector 2 is as follows: The material enters the dust collector 2 at high speed through the eccentric feed port 210, rotates at high speed along the inner wall of the dust barrel 130, and rotates downward in a spiral shape along the conical barrel 125 in this closed space. Under the action of centrifugal force, the tiny powder debris passes through the mesh holes and enters the dust channel, gradually loses power in the annular space formed by the base 124 and the dust barrel, stops rotating, and falls into the first dust collection box 1, while the material that fails to be filtered by the screen continues to leave through the discharge channel 213. The material continues to enter the vacuum hopper 5 along the suction pipeline 202, thus completing the separation process of the material and the powder debris in a closed space without additional air or devices and without polluting the external space. There is no need to consume consumables such as filter elements, and the structure is simple and convenient for maintenance-free.
[0034] To avoid the rotating wind disturbing the dust already collected in the first dust collection box 1, the base 124 is designed as a cylindrical shape, so that the separated dust debris enters the first dust collection box 1 through a specific length of annular space, realizing the functions of rotating buffering and isolating the first dust collection box 1.
[0035] Among them, the dust barrel 130 is composed of two upper and lower barrel bodies connected by bolts. As Figure 2 shown, in the structure of the dust collector 2, the dust barrel 130 of the dust collector 2 is divided into two upper and lower sections and connected by bolts. When the screen needs to be replaced, only need to disassemble the connection, remove the upper dust barrel 130, and then the conical barrel 125 can be quickly pulled out from the base 124 to complete the quick replacement.
[0036] Among them, drawer boxes 127 are arranged in the first dust collection box 1 and the second dust collection box 4, and handles 128 are arranged on one side of the drawer boxes 127 outside the first dust collection box 1 or the second dust collection box 4. Further, the first dust collection box 1 and the second integrated box are designed in a convenient replacement manner, such as can be designed as a bayonet type, a drawer type, a valve type, etc. In this implementation case, drawer boxes 127 are arranged in the first dust collection box 1 and the second dust collection box 4, and handles 128 are arranged on one side of the drawer boxes 127 outside the first dust collection box 1 or the second dust collection box 4. Loosen the knob bolt 122, and the drawer box 127 can be directly pulled out by holding the handle 128. After emptying the powder debris in the drawer box 127, install it back in the reverse order.
[0037] Among them, the suction pipeline 202 is a metal pipe or a hose made of plastic or composite materials.
