Description

Pneumatic conveying system boiling sending tank

technical field

The utility model relates to the technical field of air conveying equipment, in particular to a boiling sending tank of a pneumatic conveying system.

Background technique

The earliest prototype of air conveying was in the 19th century, when people used fans to convey wood chips and grains through pipes. By the 20th century, the powder air conveying technology has been fully developed and applied. It has been widely used in many industrial fields such as pharmaceuticals, food, plastics, cement, chemicals, glass, mining and metallurgy. Conveying granular or powdery materials through dense-phase high-pressure sending tanks is the lowest cost in air transportation. It is a batch-feeding system and is usually suitable for shorter distances in conveying pipelines and granular and better fluidity materials. , abrasive and non-abrasive materials. Such as fine quartz sand, plastic particles, etc. Its components are composed of a sending tank, an electric control system, and a delivery pipeline. However, in the prior art, due to the influence of the structure of the sending tank, the materials are prone to be detained and accumulated at the bottom of the sending tank, and the materials that remain in the sending tank for a long time are prone to deterioration or mildew, and then affect the quality of the material.

Utility model content

In order to overcome the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a boiling sending tank of a pneumatic conveying system that can efficiently transport granular or powdery materials and effectively avoid congestion and retention of materials at the bottom.

The technical solution adopted by the utility model is: a boiling delivery tank of a pneumatic conveying system, comprising:

The sending tank body, the top of the sending tank body is provided with a feed port, the first air inlet and the exhaust port, the lower side wall of the sending tank body is provided with a material outlet, and the bottom of the sending tank body is provided with a second air inlet mouth.

Further optimized, the bottom of the delivery tank is provided with a maintenance port, the maintenance port is provided with a bottom cover, the bottom cover is closed on the maintenance port through a flange seal, and the second air inlet is provided on the bottom cover. Through the optimization of this part, it is convenient for regular cleaning or maintenance of the boiling sending tank. The second air inlet is located on the bottom cover, which is more convenient for blowing the bottom material of the boiling sending tank, so that the bottom material is in a similar boiling state, and then it is convenient for the material to be discharged from the discharge port. Prevent material retention and accumulation.

A level gauge interface for installing a level gauge can be set on the top of the sending tank to facilitate the observation of internal material delivery. It can also be further sent to the top of the tank to have a safety valve interface and a pressure transmitter interface to transport materials more safely and effectively, and to regulate the internal air pressure according to the amount of internal materials.

The technical effect obtained by the utility model is: by setting the second air inlet at the bottom of the boiling sending tank of the pneumatic conveying system, the second air inlet is connected to the compressed air pipeline during use, and the material at the bottom of the boiling sending tank is always kept in a similar position through the compressed air. In the boiling state, it can effectively prevent the material from accumulating at the bottom of the boiling sending tank, or even block the discharge port, which improves the material conveying efficiency.
