Description

Technical Field

[0001] This invention relates to the field of rapeseed seedling substrate production technology, specifically to a preheated rapeseed seedling substrate raw material pretreatment equipment and its usage method. Background Technology

[0002] The front end of the preheated rapeseed seedling substrate raw material pretreatment equipment is generally a double-layer drum screen, with an upper layer of φ8 mm and a lower layer of φ3 mm, which continuously removes stones, broken roots and excessively large impurities; the outer wall of the screen cylinder is covered with a steam preheating jacket, which softens the peat fiber at a constant temperature of 60 ℃ and reduces the moisture content to 35%, thereby reducing the energy consumption of subsequent crushing. The screened material is conveyed to the magnetic separation zone by a variable frequency screw conveyor, and the permanent magnet drum removes metal foreign objects. The processing capacity is 2–3 m³·h⁻¹, the output particle size is ≤3 mm, the temperature is uniform, and it can be directly fed into the rapeseed seedling substrate batching line. During the process of removing large impurities, there is a problem that qualified materials are mixed in with the large impurities, which requires further sorting to ensure the utilization rate of raw materials. However, further sorting will increase the production cost. Therefore, in order to address the above problems, a preheated rapeseed seedling substrate raw material pretreatment equipment and its usage method are proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a preheated rapeseed seedling substrate raw material pretreatment equipment and its usage method, in order to solve the problem that in the process of removing large impurities, there are qualified materials mixed in with the large impurities, which requires further sorting to ensure the utilization rate of raw materials. However, further sorting will increase the production cost.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A preheated rapeseed seedling substrate pretreatment device and its usage method are disclosed, comprising an insulated box, a vertical plate, bearings, and a circular sieve. The vertical plate is installed inside the insulated box. A circular sieve is installed on the inner side of the upper end of the vertical plate via a bearing, forming a 10° angle with the bottom surface of the insulated box. A rejection unit is installed at one end of the circular sieve. A blocking rod is installed on one side of the upper end of the rejection unit. A driving unit is installed at one end of the circular sieve. An arc-shaped separation net is installed on the upper end of the vertical plate via a connecting rod. A heating plate is fixedly connected to the upper end of the arc-shaped separation net via a column.

[0005] As a further optimization of the present invention, the rejection unit includes a fixed ring plate, and the fixed ring plate has a plurality of square holes that are equally spaced in a ring shape inside. A rotating rod is installed inside each of the square holes, and a rotating screen is fixedly connected to one end of the rotating rod near the center point of the fixed ring plate. As a further optimization of the present invention, the rotating rod includes a vertical rod, a rotating shaft is fixedly connected in the middle of the vertical rod, a spring is installed on the outside of the rotating shaft, the rotating shaft and the spring are both installed inside the square hole, and the rotating shaft is rotatably connected to the fixed ring plate through the spring.

[0006] As a further optimization of the present invention, the rotating screen, the square hole and the rotating rod are in one-to-one correspondence, the edge of the rotating rod exposed on the fixed ring plate is arc-shaped, and the spacing between the rotating screens is 0.1cm.

[0007] As a further optimization of the present invention, the drive unit includes a motor base, which is fixedly connected to one of the upright plates by screws. A motor is fixedly connected to the upper end of the motor base, and a first pulley is fixedly connected to the top end of the motor spindle. The first pulley is connected to a second pulley by a V-belt.

[0008] As a further optimization of the present invention, the second belt pulley is arranged in a ring shape, and the second belt pulley is welded and fixed to the outer side of one end of the circular screen, and the second belt pulley and the circular screen are arranged coaxially.

[0009] As a further optimization of the present invention, there are two upright plates, which are parallel to each other, and each upright plate corresponds to a bearing.

[0010] As a further optimization of the present invention, four connecting rods are provided, each connecting rod is U-shaped, one end of each connecting rod is welded and fixed to the arc-shaped separation net, and the other end of each connecting rod is welded and fixed to the upright plate.

[0011] As a further optimization of the present invention, the barrier rod is T-shaped, and both ends of the barrier rod are fixedly connected to the heat preservation box, and the top middle part of the barrier rod is set with an inclined surface.

[0012] As a further optimization of the present invention, the heating plate and the arc-shaped separation net are both installed inside the upper part of the circular screen. The upper sides of the heating plate are arc-shaped. The heating plate and the arc-shaped separation net are parallel vertically. The distance between the heating plate and the circular screen is 0.2cm.

[0013] As a further optimization of the present invention, S1: The equipment is powered by an external industrial power supply. After the power is turned on, the motor drives the circular screen to rotate through the first belt pulley, the V-belt and the second belt pulley. During the rotation of the circular screen, the rejection unit runs automatically. S2: Material is fed from the bottom of the high end of the circular screen. Smaller particle size powdery materials fall from the bottom of the circular screen, larger particle size is blocked by the rotating screen, and the remaining medium-sized materials that meet the specifications are discharged from the other end of the circular screen. S3: During the rotation of the circular screen, the heating plate set on the inner side of the upper end continuously heats the circular screen, thereby preheating the material passing through the upper end through the heated part of the circular screen; S4: When the rotating screen inside the rejection unit moves to the top position, the rotating rod contacts the blocking rod, thereby causing the material with a larger particle size inside the rotating screen to be discharged to the top of the arc-shaped separation net. The material with a larger particle size is separated again through the arc-shaped separation net, and the unqualified material is discharged through the bottom of the arc-shaped separation net and collected by the rotating material receiving mechanism. When the rotating rod and the blocking rod are not in contact, the rotating rod, under the action of the spring, drives the rotating screen to reset; S5: Subsequently, the staff collects and uses the material discharged from the bottom of the circular screen. After further processing, the material is put back into use.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, large impurities in the material are sorted by a rejection unit. After sorting, the large impurities fall onto the upper part of the arc-shaped separation net when they move to the top of the circular screen. During the falling process, they can be separated from the qualified material through collision. Then, they are separated again by the arc-shaped separation net. The qualified material after separation falls directly to the lower part of the circular screen and mixes with the qualified material. There is no need to screen again, which improves the material utilization rate and reduces the production cost. Furthermore, by installing the arc-shaped separation net inside the circular screen, the screening effect can be further improved by utilizing the vibration during the operation of the equipment.
