Description

Technical Field

[0001] The present application relates to the field of dust removal equipment, and in particular to a dust removal device for paddy pretreatment. Background Technique

[0002] During the paddy processing and production process, it is necessary to separate the dust and outer skin attached to the surface of paddy grains. The working principle of the existing paddy dust removal device is to input paddy into the machine through a feeding hopper, and then an air flow is generated by a blower inside the machine to separate the impurities in the paddy. The impurities inside the paddy are blown out under the action of the air flow because of their relatively low density, while the paddy with a relatively high density falls downward due to the action of gravity and is sent to the lower discharge port. However, a single dust removal of paddy is not sufficient to remove the impurities in the paddy completely. It is necessary to manually transfer the paddy from the machine discharge port to the feeding hopper for secondary or even tertiary impurity removal, which is rather inconvenient. Therefore, a dust removal device for paddy pretreatment is proposed. Utility Model Content

[0003] In order to solve the problem that a single dust removal of the existing paddy is not sufficient to remove the impurities in the paddy completely, and it is necessary to manually transfer the paddy from the machine discharge port to the feeding hopper for secondary or even tertiary impurity removal, which is rather inconvenient, the present application provides a dust removal device for paddy pretreatment.

[0004] The dust removal device for paddy pretreatment provided by the present application adopts the following technical solutions:

[0005] A dust removal device for paddy pretreatment includes a processing box. A dust discharge pipe is installed through the middle of the outer surface of the processing box. A blower is arranged on one side of the outer surface of the processing box opposite to the dust discharge pipe. A plurality of groups of material boxes are arranged in the processing box from top to bottom in sequence. An electric control valve body is arranged inside the discharge port of each material box. Each material box is installed inside the processing box through a lifting mechanism, and the lifting mechanism can move the material box up and down inside the processing box.

[0006] Preferably, ball seats are fixedly connected to the outer surfaces of the material boxes. A plurality of groups of chutes are opened on the inner surface of the processing box. The chutes are arranged vertically. A lead screw is rotatably connected inside each chute. The ball seat is sleeved on the outer surface of the corresponding lead screw. A plurality of groups of motors are arranged on the upper surface of the processing box. The motors correspond to the lead screws one by one, and the power end of the motor is fixedly connected to the corresponding lead screw.

[0007] Preferably, when a plurality of groups of the material boxes are stacked, the ball seats on the surfaces of the material boxes are arranged in a stepped manner.

[0008] Preferably, the discharge port of the dust discharge pipe is arranged to incline upward.

[0009] Preferably, both the upper surface and the lower surface of the processing box are arranged to be open.

[0010] In summary, the present application includes the following beneficial technical effects:

[0017] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0018] The embodiment of the present application discloses a rice pretreatment dust removal device, including a treatment box 1, an ash discharge pipe 2 is installed through the middle of the outer surface of the treatment box 1, a fan 3 is arranged on one side of the outer surface of the treatment box 1 opposite to the ash discharge pipe 2, several groups of material boxes 4 are arranged in sequence from top to bottom inside the treatment box 1, an electric control valve body is arranged inside the discharge port of each material box 4, and each material box 4 is installed inside the treatment box 1 through a lifting mechanism, and the lifting mechanism can move the material box 4 up and down inside the treatment box 1.

[0019] Further, the discharge port of the ash discharge pipe 2 is arranged to incline upwards.

[0020] Further, both the upper surface and the lower surface of the treatment box 1 are arranged to be open.

[0021] In this embodiment, several sets of bins 4 are used in cooperation with the lifting mechanism. Before dedusting the paddy, first use the lifting mechanism to move the topmost bin 4 to the opening on the upper surface of the treatment tank 1, and move the outlet of this bin 4 above the ash discharge pipe 2 and the fan 3. Then place the paddy to be treated inside this bin 4, open the solenoid valve body at the outlet of this bin 4, and the paddy can fall from the outlet of this bin 4. When the paddy falls to the fan 3, the airflow generated by the fan 3 can blow away the impurities on the surface of the paddy and drive the impurities to be discharged from the ash discharge pipe 2, while the paddy falls into the bin 4 at the bottom of the treatment tank 1 due to gravity; after the initial dedusting of the paddy is completed, use the lifting mechanism to move the bin 4 containing the paddy to the inner top of the treatment tank 1, and then repeat the above steps to perform secondary dedusting on the paddy. In the actual use process, the number of bins 4 can be set according to the number of times the paddy needs to be dedusted. This application can automatically perform multiple impurity removals on the paddy without manual transfer of the paddy, which is convenient to use and has a good dedusting effect on the paddy.

[0022] It should be noted that: any existing model of the electric control valve component in this embodiment can be selected for cooperation to meet the simple on-off control function; at the same time, buttons can be set on the outer surface of the treatment tank 1, and a battery component can be set on the treatment tank 1 or any other part to provide corresponding power for the electric control valve component. Pressing the button can control the opening and closing of the electric control valve component; if an electric control valve component that can control the corresponding flow rate is used, a control machine can also be added as a controller for cooperation. The control machine can be selected to cooperate with a PCB control board or a micro single-chip computer, etc. Here, the model is not required.

[0023] Furthermore, ball seats 5 are fixedly connected to the outer surfaces of the bins 4, and several groups of chutes 6 are formed on the inner surface of the treatment tank 1. The chutes 6 are arranged vertically, and lead screws 7 are rotatably connected inside the chutes 6. The ball seats 5 are sleeved on the outer surfaces of the corresponding lead screws 7. Several groups of motors 8 are arranged on the upper surface of the treatment tank 1. The motors 8 correspond to the lead screws 7 one by one, and the power ends of the motors 8 are fixedly connected to the corresponding lead screws 7.

[0024] Furthermore, when several groups of bins 4 are stacked, the ball seats 5 on the surfaces of the bins 4 are arranged in a stepped manner.

[0025] In this embodiment, the ball screw is an existing transmission element, and its main function is to convert rotational motion into linear motion, which will not be elaborated here. In the actual use process, the motor 8 needs to be connected to an external power source and drive the motor 8 to rotate forward and backward to make the bin 4 move back and forth along the lead screw 7, so as to realize the lifting of the bin 4.
