The storage tank is as high as ten or so meters, and is connected with the feeding port of the top of the storage tank through a feeding pipe. When the powder and particle material tank truck transports the material to the position, the discharging pipe of the powder and particle material tank truck is butt jointed with the feeding pipe orifice of the storage tank, and then the high pressure gas generated by the pneumatic conveying system is used for conveying. Since the driver transporting the bulk material lacks the professional quality, and is careless and has no strong sense of responsibility, it is easy to misdischarge the bulk material, which causes the mixed loading of the material, such as putting the bulk ordinary portland cement into the fly ash tank, and causes that all the materials in the mixed loading tank cannot be used, resulting in economic loss and material loss.

DETAILED DESCRIPTION
[0025] AsFigures 1-2 , Figure 8 As shown, a structure for preventing accidental connection of a bulk material inlet pipe includes an inlet pipe 1, which is installed outside a tank body 14. The upper end of the inlet pipe 1 extends upward to the top of the tank body 14, and the lower end extends downward to the ground. An inlet connector 2 is fixedly connected to the inlet at the lower end of the inlet pipe 1, and the inlet connector 2 is used to connect with an unloading pipe 11. A locking plate 3 is hinged to the side wall of the inlet connector 2, and the locking plate 3 has a vertical opening 4. A first ear plate 5 is welded below the hinge point of the locking plate 3. When the locking plate 3 is vertically downward, the opening 4 of the locking plate 3 passes through the first ear plate 5 on the inlet connector 2. The first ear plate 5 has an opening, and a lock 6 is locked at the opening. The locking plate 3 is L-shaped, and when the locking plate 3 is vertically downward, the horizontal part of the locking plate 3 is located below the end of the inlet connector 2, thus preventing the truck driver from connecting the pipe for unloading on their own. The key to the lock 6 is kept by a professional. When bulk materials are fed into the tank, a professional confirms the type of material and the corresponding tank 14. After confirmation, the professional opens the lock 6 of the feed connector 2, rotates the lock plate 3 to a vertically upward position, and the opening 4 of the lock plate 3 passes through the second ear plate 13 and is hooked through the lock 6. This facilitates the truck driver to take over the control.
[0026] like Figures 3-5 As shown, to facilitate quick connection during connection, screws 7 are horizontally fixed on both sides of the feed joint 2. One end of the transition joint 8 is locked to the screws 7 via a locking assembly 9; the other end of the transition joint 8 is locked to the end of the discharge pipe 11 via a limiting clamp 10. The discharge pipe 11 is connected to a powder material tanker (mainly used for transporting dry powder materials with a particle diameter of no more than 0.1 mm, such as cement, fly ash, lime powder, etc.). The powder material tanker is fed using a pneumatic feeding system (the powder material tanker and the pneumatic feeding system are existing technologies and are not improvements in this application, so they will not be described in detail here).
[0027] like Figure 4 As shown, the locking assembly 9 includes an operating rod 9.1, with locking plates 9.2 fixed to the left and right sides of the operating rod 9.1. The lower end of the locking plate 9.2 is rotatably connected to a pin on the outer wall of the transition joint 8. The lower part of the locking plate 9.2 is provided with a locking slot 9.3, which is engaged with the screw 7.
[0028] like Figure 5 As shown, the outer opening of the locking port 9.3 is large, and the inner part that mates with the screw 7 forms a semi-circular groove, which locks the screw 7 in place. When disassembly is required, the operating lever 9.1 is rotated clockwise, and the screw 7 gradually disengages from the locking port 9.3. When the locking assembly 9 is rotated downwards, the transition joint 8 can disengage from the feed joint 2.
[0029] like Figure 5As shown, the lower end of the feed joint 2 is provided with a shoulder 2.1, and the upper end of the transition joint 8 is sleeved with the shoulder 2.1 of the feed joint 2. In order to ensure the sealing, a sealing ring can be sleeved on the shoulder 2.1, and when connected, the sealing ring is pressed at the joint of the shoulder 2.1 and the transition joint 8, so that the connection is more tight.
[0030] As shown in Figure 6 The limiting clamping head 10 is divided into multiple groups and is uniformly distributed in the circumferential direction at the bottom end of the transition joint 8. The limiting clamping head 10 is in the shape of U, and the horizontal part on one side is fixedly connected with the bottom outer wall of the transition joint 8. Multiple limiting clamping heads 10 form a limiting ring groove. The spacing between adjacent limiting clamping heads 10 is matched with the clamping block 12. When installing, the clamping block 12 of the discharge pipe 11 is aligned with the spacing between adjacent limiting clamping heads 10 and is moved upward, so that the upper end face of the discharge pipe 11 is flush with the lower end face of the transition joint 8. Then, a certain angle is rotated, the clamping block 12 enters the limiting clamping head 10, thereby realizing butt joint. When disassembling is needed, a certain angle is reversely rotated, so that the clamping block 12 is located in the spacing between adjacent limiting clamping heads 10, and the discharge pipe 11 can be separated by being pulled downward.
[0031] Working process and principle:
[0032] 1), as shown in Figure 1 ,
[0033] When the powder and particle material tank truck is in place, the professional personnel confirms the material variety and the corresponding tank body 14, confirms that there is no error, releases the corresponding lock 6, and adjusts the lock plate 3 to the state as shown in Figure 2 .
[0034] 2), take out the transition joint 8, sleeve the upper end of the transition joint 8 with the feed joint 2, then rotate the locking assembly 9, and clamp the locking assembly 9 with the screw rod 7. Then, the discharge pipe 11 is aligned with the lower end of the transition joint 8 and is rotated and locked, as shown in Figure 3 state.
[0035] 3), start the corresponding pneumatic feeding system to realize feeding.
