Abstract
Description
Technical Field
[0001] This utility model relates to the field of bulk loading technology, specifically a bulk loading machine material leveling system. Background Technology
[0002] Dry ash bulk loading machines are unloading equipment for sealed tank trucks loaded with powdery dry materials. During the loading process, due to limitations in visibility and the structure of the tank truck itself, it is impossible to accurately and intuitively monitor the actual full height of the powdery material inside the tank, which can easily lead to accidents such as overflow of powdery material or insufficient material level.
[0003] Currently, the material level devices of dry ash bulk loading machines on the market are affected by the negative pressure inside the vehicle and their own sensitivity, making it difficult to provide accurate feedback and control on the state when the material is full. They mainly rely on the operator's experience or membrane switches to control the loading of the unloading equipment. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bulk material leveling system, including an air source pipe, one end of which is connected to an air source, and the other end is connected to a three-way pipe. One outlet of the three-way pipe is connected to a pressure switch, and a pressure gauge is provided on the connecting pipe between the three-way pipe and the pressure switch. The other outlet of the three-way pipe is connected to a manual ball valve, and the manual ball valve is connected to a pressure measuring device through a pneumatic pipe.
[0006] Preferably, both the air source pipe and the air pressure pipe are flexible hoses, and the flexible hoses are installed on the telescopic unloading pipe.
[0007] Preferably, the pressure measuring device is a pneumatic pressure sensor tube, and the pressure measuring device is installed on the bulk unloading head.
[0008] Preferably, the three-way pipe, pressure gauge, and pressure switch are installed inside the control cabinet, and the control cabinet is equipped with indicator lights.
[0009] Compared with the prior art, the beneficial effects of this utility model are: by injecting a small amount of air into the tank truck using an air source, and measuring the air pressure in the hose according to the air pressure sensor tube on the bulk loading head, the fullness of the material is judged by the pressure signal. It has the characteristics of accurate signal, high sensitivity, small size, simple operation, reliable operation, convenient installation and maintenance, and can also be adjusted according to different working conditions of vehicles and different material levels.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0013] Please refer to 1. One embodiment of this utility model is provided: a bulk loading machine material level system, including an air source pipe 1. One end of the air source pipe 1 is connected to an air source, and the other end is connected to a three-way pipe 2. One outlet of the three-way pipe 2 is connected to a pressure switch 4. A pressure gauge 3 is provided on the connecting pipe between the three-way pipe 2 and the pressure switch 4. The other outlet of the three-way pipe 2 is connected to a manual ball valve 5. The manual ball valve 5 is connected to a pressure measuring device 6 through a pneumatic pipe. The air source provides air pressure, and a small amount of air is injected into the tank truck through the pneumatic pipe. The pressure measuring device 6 transmits the pressure value of the pneumatic pipe to the pressure switch 4 in a timely manner. The change in pressure is used to determine the material full state, thereby realizing accurate signal control of the material full state.
[0014] Both the air source pipe 1 and the air pressure pipe are flexible hoses. The flexible hoses are installed on the telescopic unloading pipe, which allows the hoses to extend and retract with the telescopic unloading pipe, making it easy to enter the tank truck and maintain the distance between the unloading pipe and the loaded dry ash, thereby achieving accurate pressure detection.
[0015] The pressure measuring device 6 is a pneumatic pressure sensing tube. The pressure measuring device 6 is installed on the bulk unloading head and can move with the bulk unloading head to detect the internal pressure in a timely manner.
[0016] The three-way pipe 2, pressure gauge 3, and pressure switch 4 are installed inside the control cabinet. The control cabinet is equipped with indicator lights to convert the pressure value into indicator light signals, and precise control is performed based on the changes in the indicator lights.
[0017] Working principle: During use, a small amount of air is injected into the tank truck through the air pressure sensing tube on the bulk unloading head. The bulk unloading head is equipped with an air pressure sensing tube. When the ash level in the tank truck rises and reaches the set height air pressure sensing tube on the bulk unloading head, the air pressure in the hose rises to the set value, triggering the pressure switch. At the same time, the pressure signal is transmitted to the full indicator light on the control cabinet to light up and issue a full signal. After receiving the full status signal feedback, the operator can operate to close all unloading valves and other corresponding equipment to complete one unloading and loading process.
