PTA transport vehicle for unloading of screw conveyor

Abstract

The invention relates to a PTA transport vehicle for unloading of a screw conveyor, which is characterized in that the screw conveyor and an unloading monitoring system are additionally arranged on the basis of the existing PTA transport vehicle; a spiral blade 19 is arranged at the bottom of the tank body 6, one end of the spiral blade 19 is arranged at the discharge pipe 16, the other end of the spiral blade 19 is connected with an output shaft of a motor 22 through an input shaft 21, and the motor 22 is fixed on the tank body 6; the elastic baffle plate 20 surrounds the two sides of the spiral blade 19, the lower end of the elastic baffle plate 20 is fixed on the tank body 6, and the upper end of the elastic baffle plate 20 extends into the tank body 6; the strain gauge sensor 17 is mounted at the tail part of the frame 5 and is connected with the monitor 26 through the electric wire 27; the oil pressure sensor 18 is installed on the hydraulic cylinder 2 or an oil inlet pipe of the hydraulic cylinder 2, and the oil pressure sensor 18 is connected with the monitor 26 through an electric wire 27. The PTA transport vehicle is used for increasing the unloading speed of PTA and reducing the potential safety hazard of lateral dumping of the transport vehicle.

Description

Technical field[0001]The present invention relates to a PTA transport vehicle, and a PTA transport vehicle involved in a spiral conveyor unloading.Background technique[0002]Current PTA transport vehiclefigure 1 As shown, the transport tank is mounted on the frame of the car, the upper end of the hydraulic cylinder is connected to the transport tank, the lower end of the hydraulic cylinder is connected to the frame, and the PTA is mounted in the tank of the transport tank, and the can body is equipped with an upward gas port. And the feed mouth, the rear of the can body is installed, and the boller is fixed to the discharge tube of the tank by bolt, and the outlet is connected to the bracket, the screw is connected to the stent, hand wheel Second to one end of the screw, the screw is coupled to the discharge door, and the head of the screw extends into the annular groove of the screw, so that the screw can rotate relative to the shield, and the discharge tube of the can body is equip...

AI Technical Summary

Problems solved by technology

[0004] The PTA transport vehicle has the following 4 deficiencies: (1) Because the unloading of PTA mainly relies on nitrogen blowing out of the discharge pipe, the unloading speed of PTA is slow and requires a lot of nitrogen; It is easy to accumulate arches in the body, which affects the time and quality of PTA unloading; (3) the tank body is metal, and it is impossible to see from the outside of the tank whether the PTA in the tank has been unloaded. Furthermore, it is impossible to judge whether the PTA in the tank has been unloaded. , it is difficult to ensure that the PTA in the tank is unloaded; (4) after the hydraulic cylinder lifts one end of the tank, the inclination angle of the tank is greater than the angle of repose of the PTA, and one end of the tank is higher, so that the center of gravity of the PTA transport vehicle is higher. There is a safety hazard of sideways dumping, PTA is flammable and explosive, and the sideways dumping of the PTA transport vehicle will cause PTA to burn and explode
