Filtering and recycling system of suction pressure feed tank truck and suction pressure feed tank truck

Abstract

The invention relates to a filtering and recycling system of a suction pressure feed tank truck and the suction pressure feed tank truck. The filtering and recycling system comprises a recycling pipeline, a cloth bag filtering device and a cyclone separating device, and further comprises a flow control assembly, wherein the cloth bag filtering device and the cyclone separating device communicate with each other; one end of the recycling pipeline communicates with both the cloth bag filtering device and the cyclone separating device; the other end of the recycling pipeline is used for communicating with a storage tank; the flow control assembly comprises a flow detecting element, a control element and a valve; the valve is arranged on the recycling pipeline and positioned at the end close to the storage tank; the flow detecting element is arranged on the recycling pipeline and used for detecting the material flow in the recycling pipeline; the output end of the flow detecting element iselectrically connected with the input end of the control element; and the output end of the control element is electrically connected with the input end of the valve. The suction pressure feed tank truck comprises the above filtering and recycling system. Therefore, the recycling pipeline can be effectively prevented from being blocked during back suction, and then the normal use of the filteringand recycling system can be guaranteed.

Description

Technical field[0001]The invention relates to the technical field of suction and pressure feeding tank cars, and more specifically, it relates to a filter recovery system of a suction pressure feeding tank car and a suction pressure feeding tank car.Background technique[0002]The suction and pressure delivery tanker is a comprehensive principle of negative pressure pneumatic conveying and positive pressure pneumatic conveying of materials, and organically combines the two kinds of pneumatic conveying, using air as the carrier of material conveying, and realizing automatic suction of materials in a closed space. Special production equipment for materials, airtight transportation and automatic discharge. The suction and pressure delivery tanker is the transportation of dust materials such as ironmaking, steelmaking, sintering, coking, smelting desiliconization, desulfurization, dephosphorization, blast furnace, converter dust ash, etc. The entire suction, transportation and discharge p...

Problems solved by technology

However, in the recovery pipeline of the existing filtration recovery system, the valve is usually located at one end close to the bag filter device. When the back suction method is used, the material is easy to enter the recovery pipeline, causing the recovery pipeline to be blocked.

[0006] In addition, the hose quick connectors are often used to connect the various pipe sections in the recovery pipeline. The rubber hose quick connectors will wear out after a long time of use. If they are not replaced in time, the connection is not strong enough and the pressure bearing capacity is not enough Burst problem, there is a certain security risk

[0007] To sum up, in the existing filter recovery system for sucking and pressure-feeding tank trucks, the recovery pipeline has the defects of easy clogging when sucking back, easy wear and tear of the connecting structure, low service life, difficult maintenance and certain potential safety hazards
