Description

Technical Field

[0001] The invention belongs to the technical field of wood pulp granulation, and specifically refers to a production device for efficiently and energy-savingly manufacturing environmentally friendly granules and a use method thereof. Background Art

[0002] Environmentally friendly pellets made from wood pulp have multiple uses. They can be used as soil and water conservation aids to preserve soil moisture and facilitate plant growth. They can also be used as pet bedding to keep the cage environment clean. The process of manufacturing similar environmentally friendly wood pulp pellets usually includes the main steps of raw material pretreatment, stirring and mixing, pellet making, and drying and dehydration. In order to solve the energy waste caused by the need to add water to granulate and then dry out the excess water in the current environmentally friendly pellet production process, and at the same time improve production efficiency. Innovative upgrades are made to the existing granulation equipment so that the raw materials can be granulated without adding water, thereby reducing subsequent drying energy consumption and improving overall production efficiency.

[0003] The Chinese patent with publication number CN210385769U proposes a new type of granulation drum mechanism of a rotary drum granulator. In view of the existing granulation drum and drying steps being carried out separately, the drum is first required to granulate the material, and then the granulated material is manually put into the drying device, which undoubtedly affects the production efficiency of the rotary drum granulator. The following scheme is now proposed, which includes a fixed seat, a rotary drum and a drying box. The rotary drum and the drying box are both fixedly installed with the top of the fixed seat. A discharge pipe is arranged at the center of one side of the rotary drum, and one end of the discharge pipe extends into the drying box. The inner wall of the top of the drying box is rotatably connected with a stirring shaft, and the top of the stirring shaft extends to the top of the drying box and is fixedly installed with a power assembly. The present invention provides a drying device on the main body of the rotary drum mechanism, so that the material particles discharged from the rotary drum can be directly dried, thereby greatly improving the production efficiency of the rotary drum granulator. However, the particles produced in this scheme need to be connected to the drying due to the high moisture content, which increases the production cost. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the process of wood pulp granulation in the prior art requires the addition of water for granulation and then dehydration, which results in high production energy consumption and low efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: The present invention proposes a high-efficiency and energy-saving production equipment for manufacturing environmentally friendly particles, including a bracket, a negative pressure chamber is provided above the bracket, an air suction box upper mold is provided above the negative pressure chamber, a feeding port extends from the side of the air suction box upper mold away from the negative pressure chamber, a brush is provided on the inner top wall of the air suction box upper mold, an adjusting damper is hinged on the side wall of the negative pressure chamber, an exhaust hole is provided at a position corresponding to the adjusting damper on the bracket, a raw material adsorption and conveying mechanism is provided in the negative pressure chamber on the bracket, and the brush is provided above the raw material adsorption and conveying mechanism.

[0006] As an improvement, the raw material adsorption and conveying mechanism includes an adsorption mesh belt, a transmission shaft and a transmission motor. The adsorption mesh belt rotates on a bracket, the transmission shaft is wrapped around the adsorption mesh belt, one end of the transmission shaft is arranged in the negative pressure chamber and the other end leaks out of the negative pressure chamber, and the transmission motor is connected to the adsorption mesh belt.

[0007] As an improvement, the bracket is also provided with an adsorption fan, and the adsorption fan performs adsorption work to adsorb the raw materials onto the adsorption mesh belt.

[0008] A method for using a production device for efficiently and energy-savingly manufacturing environmentally friendly particles comprises the following steps:

[0009] Step 1: Use the existing opener and fiber collection device to pre-treat the wood pulp raw materials by loosening and collecting;

[0010] Step 2: The pre-treated wood pulp raw material enters the upper mold of the suction box through the feeding port;

[0011] Step 3: The wood pulp raw material falls onto the adsorption mesh belt;

[0012] Step 4: The adsorption fan works to adsorb the raw materials onto the adsorption mesh belt;

[0013] Step 5: Start the transmission motor, which drives the transmission shaft to work, so that the adsorption mesh belt moves toward the brush (5);

[0014] Step 6: Adjust the distance between the brushes to control the discharge thickness, gap and feed rate;

[0015] Step 7: The raw materials are separated by brushes and then continue to move on the adsorption mesh belt;

[0016] Step 8: The raw material leaves the adsorption mesh belt and falls into the subsequent processing equipment, where it is rolled and cut into particles.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: the present invention proposes a highly efficient and energy-saving production equipment for manufacturing environmentally friendly particles, the front end of which belongs to a negative pressure environment, and the pre-treatment equipment can ensure the working environment in the negative pressure chamber, so that the feed is evenly distributed on the adsorption mesh belt, the working rate of the granulator is maximized, and the setting of the adjustable damper can control the air intake of the negative pressure chamber, and at the same time the feed situation can be observed to maintain the power balance of the adsorption fan;

[0018] In addition, the brush can be set to control the wood pulp raw materials on the adsorption mesh belt, so that it can enter the granulator with appropriate thickness and arrangement gap, avoiding the situation where the granulator is blocked due to uneven feeding and insufficient moisture, thereby reducing production efficiency;

[0019] The feed port of this device is connected to the fiber collecting machine, and the dust generated during operation will be recovered by it, further reducing the loss of raw materials and improving the yield. No water is added in the whole process, and the method of waterless granulation is adopted. The wood pulp raw materials are conveyed by an adsorption mesh belt, which ultimately achieves the technical effect of reducing production time, reducing energy consumption and improving the overall granulation efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] like Figure 1-3 As shown, the present invention proposes a production equipment for efficiently and energy-savingly manufacturing environmentally friendly particles, including a bracket 1, a negative pressure chamber 2 is provided above the bracket 1, an air suction box upper mold 3 is provided above the negative pressure chamber 2, a feeding port 4 extends from the side of the air suction box upper mold 3 away from the negative pressure chamber 2, a brush 5 is provided on the inner top wall of the air suction box upper mold 3, an adjusting damper 6 is hinged on the side wall of the negative pressure chamber 2, an exhaust hole 7 is provided at a position corresponding to the adjusting damper 6 on the bracket 1, a raw material adsorption and conveying mechanism 8 is provided in the negative pressure chamber 2 on the bracket 1, and the brush 5 is provided above the raw material adsorption and conveying mechanism 8.

[0026] As an improvement, the raw material adsorption and conveying mechanism 8 includes an adsorption mesh belt 9, a transmission shaft 10 and a transmission motor 11. The adsorption mesh belt 9 rotates on the bracket 1, and the transmission shaft 10 is arranged to be wrapped around the adsorption mesh belt 9. One end of the transmission shaft 10 is arranged in the negative pressure chamber 2 and the other end leaks out from the negative pressure chamber 2. The transmission motor 11 is connected to the adsorption mesh belt 9.

[0027] As an improvement, the support 1 is further provided with an adsorption fan 12 , which performs adsorption work to adsorb the raw materials onto the adsorption mesh belt 9 .

[0028] A method for using a production device for efficiently and energy-savingly manufacturing environmentally friendly particles comprises the following steps:

[0029] Step 1: Use the existing opener and fiber collection device to pre-treat the wood pulp raw materials by loosening and collecting;

[0030] Step 2: The pre-treated wood pulp raw material enters the upper mold 3 of the suction box through the feeding port 4;

[0031] Step 3: The wood pulp raw material falls onto the adsorption mesh belt 9;

[0032] Step 4: The adsorption fan 12 works to adsorb the raw materials onto the adsorption mesh belt 9;

[0033] Step 5: Start the transmission motor 11, which drives the transmission shaft 10 to work, so that the adsorption mesh belt 9 moves toward the brush 5;

[0034] Step 6: Adjust the distance between the brushes 5 to control the discharge thickness, gap and feed rate;

[0035] Step 7: The raw materials are separated by the brush 5 and then continuously moved on the adsorption mesh belt 9;

[0036] Step 8: The raw material leaves the adsorption mesh belt 9 and falls into the subsequent processing equipment to be rolled and cut into particles.

[0037] When in use, the wood pulp raw material is loosened by the pre-treatment opener and collected by the fiber collecting device. Then the fiber collecting machine is connected to the feed port 4 and the raw material is fed into the bracket 1. The blower and adsorption fan at the fiber collecting machine end ensure the normal environment in the negative pressure chamber 2 with a certain power. The feed can be evenly distributed on the adsorption mesh belt 9 to maximize the working rate of the granulator. The air intake of the negative pressure chamber can be controlled by adjusting the damper 6. At the same time, the feed situation can be observed to maintain the power balance of the adsorption fan 12. The raw material enters the suction box through the feed port 4.

When the raw materials reach the position of the brush 5, they are separated by the brush 5 and continue to move with the adsorption mesh belt 9. Finally, they pass through the adsorption mesh belt 9 and fall into the equipment of the next step for pressing rollers and slitting to be made into particles to realize waterless granulation.
