Description

Technical Field

[0001] This invention relates to the field of discharge port cleaning equipment, and more particularly to a device for preventing material accumulation at the discharge port. Background Technology

[0002] Currently, due to the inherent viscosity of the materials used, when the materials pass through some deep feed inlets during the feeding process, some material easily adheres to and accumulates inside the inlets, resulting in material buildup. This buildup gradually increases over time, causing numerous problems for the production process. Because these feed inlets are quite deep, personnel often struggle to reach deeper areas during cleaning, making it impossible to completely remove the buildup. Furthermore, cleaning may require the use of auxiliary tools or special postures to attempt to remove the buildup from deeper feed inlets, which undoubtedly increases the risk of injury and poses certain safety hazards.

[0003] Therefore, a device is provided to prevent material accumulation at the discharge port to solve the above-mentioned problem. Utility Model Content

[0004] The main purpose of this invention is to solve the problem that in the prior art, cleaning the feed inlet is usually done manually, which often requires the use of auxiliary tools or special postures to try to clean the accumulated material in the deeper feed inlet, which can easily lead to personnel injury and insufficient safety.

[0005] This utility model provides a device for preventing material accumulation at the discharge port, the device comprising:

[0006] A number of gas ejection mechanisms with different cross-sectional perimeters are arranged on the inner wall of the feed port from top to bottom. Two adjacent gas ejection mechanisms are connected by a pipeline. The uppermost gas ejection mechanism is connected to an air compressor by a pipeline. A solenoid valve is installed on the pipeline between the gas ejection mechanism and the air compressor.

[0007] Optionally, the gas ejection mechanism consists of several elbows, several four-way connectors, and several nozzle pipes. The elbows are connected to each other through four-way connectors or nozzle pipes. The several elbows, several four-way connectors, and several nozzle pipes are connected to form a ring. The diameter of the outer circle of the ring is the same as the diameter of the cross-section of the discharge port at the pipe installation location of the gas ejection mechanism. The nozzle pipe includes a rigid air pipe and a high-pressure gas nozzle installed on the rigid air pipe. The high-pressure gas nozzle is arranged facing the side wall of the discharge port.

[0008] Optionally, the positions of the four-way valves on two adjacent gas ejection mechanisms are corresponding, and the lower port of the upper four-way valve and the upper port of the lower four-way valve are connected by a support pipe.

[0009] Optionally, the upper ports of all four-way valves on the topmost gas ejection mechanism are simultaneously connected to the air compressor via solenoid valves.

[0010] Optionally, the upper ports of each four-way valve on the topmost gas ejection mechanism are connected to an air compressor via a solenoid valve.

[0011] Optionally, the number of four four-way valves is four, and the four four-way valves are evenly distributed on the gas ejection mechanism.

[0012] Optionally, it also includes several clamps for fixing the uppermost gas ejection mechanism to the side wall of the discharge port by bolts.

[0013] Optionally, a hook is also included, the upper end of which is hung on the upper end of the side wall of the discharge port, and the lower end of which is used to hang the gas ejection mechanism.

[0014] Optionally, the switching signal of the solenoid valve is interlocked with the operating signal of the upstream belt conveyor.

[0015] The advantages of this utility model are as follows: It adopts a modular design, which can be spliced ​​and used. It can be matched according to the actual situation for discharge ports of different diameters and depths, with a wide range of adaptability and strong usability. In addition, the installation process is relatively simple. Only the pipe on the top side needs to be fixed to complete the installation, saving disassembly and installation time. Furthermore, maintenance is simple. Only some parts need to be replaced, without replacing all of them, thus saving costs. Attached Figure Description
