Powdery and granular material tank car telescopic charging pipe with positioning guiding function

Abstract

The invention relates to a powdery and granular material tank car telescopic charging pipe with a positioning guiding function. The charging pipe comprises a charging pipe body; the charging pipe body comprises an outer casing pipe, a middle casing pipe and a conical discharging pipe; the wide end of the conical discharging pipe is connected with the lower end of the middle casing pipe through a deformable lower soft connecting pipe in a sealed manner, and the conical discharging pipe is communicated with the outer casing pipe through a lower soft connecting pipe; a telescopic driving mechanism for driving the middle casing pipe to stretch in and draw out in the outer casing pipe is arranged outside the outer casing pipe, and when the telescopic driving mechanism drives the middle casing pipe to stretch in and draw out in the middle casing pipe, the conical discharging pipe can synchronously move along with the middle casing pipe so as to enable the conical discharging pipe to be away from or close to the outer casing pipe; and when the telescopic driving mechanism drives the middle casing pipe to stretch out of the interior of the outer casing pipe, the narrow end of the conical discharging pipe can stretch into a feeding opening of a tank car. The powdery and granular material tank car telescopic charging pipe is compact in structure, the tank car can be effectively guided to be in place, it can be ensured that the tank car can be rapidly in place, personal safety hidden troubles are removed, the car loading time is shortened, and safety and sanitation of food can be ensured.

Description

technical field [0001] The invention relates to a charging pipe, in particular to a telescopic charging pipe for a powder and granular tanker with positioning guidance, belonging to the technical field of the tanker's charging pipe. Background technique [0002] Compared with the traditional bagged transportation of powder materials, the bulk transportation of powder materials can reduce the packaging, stacking, loading, transportation, unloading, unpacking and other links of powder materials, and not only save equipment configuration, personnel input, storage and so on in each link. The investment in the site can also eliminate the pollution of the powder to the environment and the pollution of the environment to the powder during the circulation process, and ensure the safety and hygiene of the powder. Therefore, the bulk transportation of powder materials is a technological revolution in the field of circulation. [0003] Flour has been transported in bulk in foreign coun...

AI Technical Summary

Problems solved by technology

[0003] Flour has been transported in bulk in foreign countries for more than half a century, and the flour bulk transport rate in economically developed countries has reached more than 70%. In recent years, our country’s awareness of flour bulk transport has been increasing. The tanker transportation method, flour bulk distribution and receiving process technology and equipment are becoming more and more mature, but when the tanker is loaded, there are problems with the positioning of the tanker, the filling rate of the tanker, and the dust control during the distribution process, material residual pollution, fly pollution, and distribution output. Such problems are problems that cannot be solved or avoided by the existing telescopic hose structure, and also restrict the popularization and development of bulk transportation to a certain extent.

[0004] The existing telescopic hose includes an inner telescopic pipe, an outer telescopic pipe and a tapered outlet pipe. The inner telescopic pipe is composed of multiple sections of stainless steel tapered pipes connected in series through steel wire ropes and then set in the outer telescopic cloth tube sewn by canvas. The lower end of the cloth drum is fixedly connected with a tapered outlet pipe. Through a set of worm gear hoisting mechanism at the upper end of the feed inlet, the steel wire rope is driven to make the inner telescopic pipe and the outer telescopic pipe vertically expand and contract. The transmission mechanism is heavy in size and weight, and has no positioning guide device. , the operation is completely dependent on the experience and technology of the operator and the tanker driver to align the position of the tanker top inlet, which is very troublesome and likely to cause safety for the roof workers

[0005] In addition, because the loading is all installed outdoors, when the existing loading hose is not working, the discharge hopper is not airtight, which often leads to the entry of insects and flies, which may be damaged by malicious throwing of foreign objects. The fall is serious; also because the outer stretchable cloth drum is made of canvas, the outer wall of the cloth drum is exposed at the loading site, which is easy to absorb and accumulate dust and attract flies and insects to attach. When the cloth drum is damp, it is easy to breed bacteria and insect eggs. The falling directly affects the sanitation of the loading environment, and the creases on the inner wall of the cloth drum are prone to residual powder, resulting in mildew and insects, which will directly fall into the tanker to pollute the product and affect food hygiene
