Abstract

The utility model relates to a pneumatic conveying throat pipe. The pneumatic conveying throat pipe comprises a horizontal pipe and a feed pipe, wherein the horizontal pipe is coaxial with a conveying pipeline and is communicated with the conveying pipeline, and the feed pipe is communicated with the horizontal pipe and is perpendicularly connected with the horizontal pipe. Materials enter the horizontal pipe through the feed pipe and then enter the conveying pipeline through the horizontal pipe. The horizontal pipe is further provided with an air supply pipe which is communicated with and perpendicular to the horizontal pipe, the air supply pipe is provided with an air flow regulator used for regulating air pressure inside the horizontal pipe, and the horizontal pipe is further provided with a pressure transmitter used for detecting the air pressure inside the horizontal pipe and controlling the air flow regulator according to the air pressure. The air flow regulator and the pressure transmitter are arranged on the horizontal pipe, the pressure transmitter detects the air pressure inside the horizontal pipe and accordingly controls the air flow regulator to regulate the air pressure inside the horizontal pipe, the ratio of the materials to air can reach a proper value, blocking of the throat pipe is prevented effectively, and the conveying efficiency is improved.

Description

Air-flow is carried trunnion
Technical field
The utility model relates to the mass transport field, and particularly a kind of air-flow is carried trunnion.
Background technology
Air-flow is carried the method for (powder or particle) material, is a kind of advanced method that the industrial process material shifts.Along with the upgrading of industrial technology and the raising of cleaner production requirement, its utilization is more and more extensive.The method of air-flow convey materials can be divided into malleation mode of movement and negative pressure transportation mode.The principle of negative pressure transportation is: rely on internal pressure to be lower than the air stream of external atmospheric pressure, the material wrapped folder that will be sent reaches the purpose of conveying with air motion in pipeline in the air-flow of certain flow rate.The material that negative-pressure air-flow is carried is to enter airflow pipeline by trunnion.As shown in Figure 1, the structure of conventional trunnion is one of tool by supply pipe 1 and has an air intlet and the levelling pipe 2 of a gas material mixture outlet forms.Conventional trunnion feed, material produces accumulation in trunnion when feeding coal is large, makes material-gas ratio excessive, air-flow is difficult to drive material movement, causes trunnion and pipe choking, if feed very little, the gas material is than little, causes gas consumption large, it is low to transport efficient, the cost height.
Summary of the invention
The purpose of this utility model provides a kind of high and energy-conservation air-flow of efficient that transports and carries trunnion.
For achieving the above object, the technical solution adopted in the utility model is: a kind of air-flow is carried trunnion, it is installed on the delivery duct, it comprises levelling pipe coaxial with delivery duct and that be connected and arrange, be connected and the perpendicular supply pipe that is connected with described levelling pipe, material enters described levelling pipe by described supply pipe, entered in the described delivery duct by described levelling pipe again, be provided with coupled logical and perpendicular blowdown pipe on the described levelling pipe, be provided with on the described blowdown pipe be used to the air volume regulator of regulating described levelling pipe internal gas pressure, also be provided with on the described levelling pipe for detection of the air pressure in the levelling pipe and according to the big or small pressure transformer of controlling air volume regulator of air pressure.
Further, the described levelling pipe end that is connected with described delivery duct is air extractor duct, and its other end is admission port, is provided with air filter on the described admission port.
Further, described pressure transformer is arranged on the levelling pipe between described supply pipe and the air volume regulator.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model arranges air volume regulator and pressure transformer at levelling pipe, thereby the control of the air pressure in pressure transformer detection level pipe air volume regulator is regulated the air pressure in the levelling pipe, make material-gas ratio reach suitable ratio, effectively prevent the trunnion obstruction, improved transport efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation that conventional air-flow is carried trunnion;
Accompanying drawing 2 is the structural representation that air-flow of the present utility model is carried trunnion;
Accompanying drawing 3 is carried the structural representation of trunnion for two air-flows are set on the delivery duct;
In the accompanying drawing: 1, supply pipe; 2, levelling pipe; 3, material bin; 4, blowdown pipe; 5, pressure transformer; 6, air volume regulator; 7, delivery duct; 8, air filter; 21, admission port; 22, air extractor duct.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
As shown in Figure 2, this air-flow carries trunnion to comprise and the be connected levelling pipe 2 that arrange coaxial with delivery duct 7, be connected with levelling pipe 2 and the perpendicular supply pipe that is connected 1, be arranged on the levelling pipe 2 and coupledly lead to and perpendicular blowdown pipe 4, be arranged on air volume regulator 6 on the blowdown pipe 4, be installed in the pressure transformer 5 on the levelling pipe 2 between supply pipe 1 and the blowdown pipe 4, levelling pipe 2 end that is connected with delivery duct 7 is air extractor duct 22, its other end is admission port 21, and air-flow carries trunnion also to comprise the air filter 8 that is installed on the admission port 21.
After delivery duct 7 produces negative pressure, material enters levelling pipe 2 from material bin 3 through supply pipe 1, entered in the delivery duct 7 by levelling pipe 2 again, under the barometric pressure combined action of delivery duct 7 interior negative pressure and admission port 21, produce the gas material mixed airflow of certain flow rate, and be transported to the destination along delivery duct 7.Pressure transformer 5 is the pressure of detection level pipe 2 interior gas material mixing sections constantly, replenish negative regulation in air volume regulator 6 holding tubes by regulating, when pressure transformer 5 detects negative pressure above after the setting value, control air volume regulator 6 increases aperture, lower material-gas ratio and prevent that trunnion from stopping up, when detect negative pressure very little after, control air volume regulator 6 reduces aperture, increases material-gas ratio to improve transport efficiency.
As shown in Figure 3, when the needs multiple feed, when improving feed efficient, can set up air-flow at delivery duct 7 and carry trunnion, the trunnion that is positioned at delivery duct 7 middle parts need to be with air filter 8 removals, and directly being connected with delivery duct 7 to arrange gets final product.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modification all should be encompassed within the protection domain of the present utility model.
