Description

Technical Field

[0001] The invention belongs to the application fields of agriculture and industry, and specifically relates to a device for continuously transferring granular materials under low pressure conditions. Background Art

[0002] The short-distance transfer and transmission of granular materials in the industrial and agricultural fields is common. Currently, the short-distance transfer, storage, and material addition of granular materials on the market are mostly achieved by screws and conveyor belts (Internet procurement platform). This type of machine has high transmission efficiency, but the transmission distance is fixed, the device is bulky, and it is necessary to manually add materials to the feed port. In addition, the material input and output ends of this screw and conveyor belt transfer method are too exposed, which will inevitably produce more dust pollution. Summary of the invention

[0003] In view of the above problems, the purpose of the present invention is to propose a granular material transfer and transmission device with flexible transmission distance, simple manual operation and no excessive dust pollution.

[0004] The technical solution of the present invention is: a device for continuously transferring granular materials under low pressure conditions described in the present invention comprises a pressure-resistant barrel, and a screw output device is connected to the bottom end of the pressure-resistant barrel.

[0005] Furthermore, a motor is externally connected to one end of the screw output device, and a movable flap is disposed at a front end discharge port of the screw output device.

[0006] Furthermore, a negative pressure device is arranged on the top of the pressure-resistant barrel.

[0007] Furthermore, a suction pipe is connected to the pressure-resistant barrel.

[0008] Furthermore, the negative pressure device is a motor / exhaust fan.

[0009] Furthermore, the pressure-resistant barrel and the screw output device are connected via a conical hopper or a circular hopper, and the connection parts are connected by welding / riveting.

[0010] Furthermore, the internal pressure of the pressure-resistant barrel during operation is lower than the external pressure.

[0011] The beneficial effects of the present invention are: the device continuously transfers granular materials under negative pressure conditions, can effectively reduce dust pollution, the efficiency can be adjusted according to demand, and when the instrument is running, only the suction pipe needs to be controlled, and a single person can complete the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the present invention;

[0013] In the figure: 1 is a negative pressure device, 2 is a pressure-resistant barrel, 3 is a suction pipe, 4 is a movable flap, 5 is a screw output device, and 6 is a motor. DETAILED DESCRIPTION

[0014] The specific technical scheme of the present invention is further described in detail below with reference to specific examples.

[0015] As shown in the figure, the device for continuously transferring granular materials under low pressure conditions described in the present invention includes a negative pressure device 1, a pressure-resistant barrel 2, a suction pipe 3, a movable flap 4, a screw output device 5, and a motor 6;

[0016] The present invention creates a low-pressure environment in the pressure-resistant barrel 2 through the negative pressure device 1, automatically sucks the material into the pressure-resistant barrel 2, and then transfers the material in the pressure-resistant barrel 2 out through the screw output device 5.

[0017] Furthermore, the screw output device 5 and the pressure-resistant barrel 2 are connected via a conical hopper, and the connection portion is strong and resistant to low pressure (welding / riveting).

[0018] Furthermore, the screw output device 5 is driven by a motor 6, and the motor 6 and the outside of the screw output device 5 are connected together.

[0019] Furthermore, the discharge port end of the screw output device 5 is provided with a movable flap 4, which automatically closes under the action of suction when the internal pressure of the pressure-resistant barrel 2 is lower than the external pressure. When the material is sucked into the pressure-resistant barrel 2 and the screw output device 5 is running, the pressure difference at both ends of the flap will be offset.

[0020] Furthermore, the material suction efficiency and the output efficiency of the screw output device 5 can be adjusted by the motor 6 .

[0021] Example: Continuous transmission of rice:

[0022] When the device is running, it can achieve:

[0023] 1. The operation of the screw output device 5 does not affect the low-pressure environment in the pressure-resistant barrel 2;

[0024] 2. The suction and discharge of rice materials are carried out continuously.

[0025] The key technical points of the present invention are:

[0026] 1. The operation of the screw output device 5 does not affect the low-pressure environment in the pressure-resistant barrel 2;

[0027] 2. The suction and discharge of materials are carried out continuously.

[0028] Comparative Example:

[0029] At present, granular materials on the market are mostly transported by screws and conveyor belts. This method has a fixed transmission distance and the device is bulky, and it requires manual labor to continuously add materials to the feed port. In addition, the material input and output ends of the existing screw and conveyor belt transfer methods are too exposed, which will inevitably produce more dust pollution.

[0030] The present invention can continuously transfer granular materials, and the efficiency can be adjusted according to the needs by adjusting the motor power of the negative pressure device 1 and the screw output device 5; the material transmission distance of the present invention is flexible (only the suction pipe device 3 of different lengths needs to be replaced), the manual operation is simple, and no excessive dust pollution is generated, which is of great significance to the development of industry and agriculture and the health protection of workers.
