Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment in factories, and in particular to a self-priming suction gun with stable operation. Background Technology

[0002] In factory processing and production, products or raw materials need to be continuously transported. Especially for powdery, granular, or liquid materials, screw conveyors are generally used for continuous material transport. However, during the conveying process, the screw blades can cut granular materials, causing material crushing and other problems that interfere with subsequent processing.

[0003] Meanwhile, the spiral blades are generally made of iron, which is prone to rust and may contaminate the material when in contact with it. If the blades are made of non-metallic materials, such as plastic, the plastic will wear down during long-term conveying, resulting in impurities in the material.

[0004] Therefore, current conveying equipment may experience untimely or unstable operation after prolonged use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a self-priming suction gun with stable operation.

[0006] The technical solution of this utility model is: a self-priming suction gun with stable operation, comprising:

[0007] The suction pipe is arranged vertically, with the lower end of the suction pipe being the inlet and the upper end being the outlet.

[0008] The material suction unit is disposed outside the material suction pipe and communicates with the inside of the material suction pipe for material suction drive. The material suction unit includes:

[0009] The installation tube is disposed outside the suction tube and the two are internally connected, and the installation tube and the suction tube are inclined.

[0010] A drive source is provided, which is mounted on the mounting tube and the drive end of the drive source is located inside the mounting tube. A suction valve core is provided at the drive end, and the suction valve core moves back and forth under the drive of the drive source. When the suction valve core is completely inserted into the suction tube, the suction tube is cut off.

[0011] Furthermore, the driving source is any one of a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0012] Furthermore, the suction valve core has its working surface set at an angle. The angled working surface of the suction valve core can better isolate the suction pipe.

[0013] Furthermore, the outlet direction of the mounting tube and the suction tube is inclined at an acute angle. This ensures that the suction process is continuous and upward.

[0014] Furthermore, the feed inlet is provided with a feed notch, which is located on the side wall of the suction pipe. The feed notch ensures smooth feeding.

[0015] Furthermore, the feed notch is no more than 10 centimeters above the lower end of the suction pipe.

[0016] Furthermore, the feed notch can be U-shaped, circular, triangular, or quadrilateral. An inverted U-shape is generally the most common.

[0017] Furthermore, an air replenishment unit is also provided, the air replenishment unit comprising:

[0018] Lower air supply port, the lower air supply port is located on the side wall of the suction pipe and below the suction valve core; and / or

[0019] The upper air supply hole is located on the side wall of the suction pipe and on the upper side of the suction valve core.

[0020] Furthermore, a protective cover is installed on the outside of the lower air inlet. The lower end and both sides of the protective cover are sealed to the outer wall of the suction pipe, while the upper end of the protective cover is open, forming a protective channel between the protective cover and the outer wall of the suction pipe. This protective channel ensures that the lower air inlet can still supply air normally when the suction pipe is inserted into the material.

[0021] Furthermore, at least two lower air inlet holes are provided, and they are arranged vertically. This ensures air supply at different heights and guarantees smooth flow of the material.

[0022] Furthermore, an air supply pipe is connected to the outside of the upper air supply hole, and a filter is installed on the outside of the air supply pipe. The filter ensures the cleanliness of the supplied air and prevents impurities from contaminating the material.

[0023] Furthermore, an air supply pipe is connected to the outer side of the upper air supply hole, and an adjusting valve is installed inside the air supply pipe. The adjusting valve is rotatably mounted inside the air supply pipe, and an adjusting shaft extends outward. By rotating the adjusting shaft, the adjusting valve can be rotated to control the amount of air supplied. For example, adjustments can be made according to different materials such as granular or powdered materials to ensure smooth material conveying.

[0024] A specific setup could be to have two holes in the diameter of the air supply pipe, a rotation center at the lower end of the regulating valve plate which is fitted into the holes, and a rotary knob at the upper end. The rotary knob serves as a rotation axis and is connected to the regulating valve plate. At least part of the rotary knob is exposed above the holes, allowing for easy adjustment by the user.

[0025] The beneficial technical effects of this utility model are: by using this drive source to reciprocate to push the valve core to drive the raw material for conveying, it can be ensured that the raw material is conveyed under the action of air, and the material body only contacts the suction pipe, so as to achieve the effect of continuous conveying. It also ensures the integrity of the material body and avoids secondary wear on the material body during the conveying process, thus providing a safe and reliable guarantee for subsequent processing.

[0055] Furthermore, an air supply pipe 6 is connected to the outer side of the upper air supply hole 41. An adjusting valve 8 is installed inside the air supply pipe 6, rotatably mounted within the pipe, and an adjusting shaft 9 extends outwards from it. By rotating the adjusting shaft 9, the adjusting valve 8 can be rotated, controlling the amount of air supplied. For example, adjustments can be made according to different material types such as granular or powdered materials to ensure smooth material conveying.

[0056] The specific setup can be as follows: two holes are set in the diameter direction of the air supply pipe 6, the lower end of the regulating valve plate 8 is set with a rotation center and is fitted into the hole, and the upper end is set with a rotary knob.
