Embodiment 1

[0033] Please combine further figure 2 , this embodiment provides an automatic powder feeding device, including a receiving bin 100 and an automatic feeding mechanism.

[0034] In this embodiment, the material receiving bin 100 has a round platform structure as a whole, and the diameter of the feeding port is larger than that of the discharging port, which is convenient for discharging. The receiving bin 100 is preferably made of steel and other materials, and has high structural strength. Furthermore, the end where the feed port of the receiving bin 100 is located is also provided with a sealing sleeve that seals the docking area of ​​the bulk powder tanks such as the bulk cement storage tank 1 and the receiving bin 100, so as to prevent leakage of the powder and is safe and environmentally friendly. Preferably, the sealing sleeve is an elastic ferrule, such as an elastic rubber sealing sleeve, which is wear-resistant, has good elasticity and has a long service life.

Embodiment 2

[0041] Please combine further image 3 , this embodiment provides an automatic powder feeding device, including a feeding bin 100 and an automatic feeding mechanism. One end of the cylinder is arranged on the outer wall of the material receiving bin 100, and the piston rod of the cylinder 322 is connected to the other end of the driving rod, which is used to drive the valve plate to automatically close the material through hole.

[0042] The automatic powder feeding device of this embodiment makes the cylinder 322 open the material through hole through the conversion of the cylinder to realize the automatic feeding of the powder into the buffer tank 200, and then adjusts the pressure in the buffer tank 200 by automatically supplying high-pressure gas to the buffer tank 200. The air pressure cooperates with the cylinder 322 to drive the piston rod, so that the valve plate automatically closes the material through hole, and at the same time relies on the air pressure in the buffer...

Embodiment 3

[0044] Please combine further Figure 4 , this embodiment provides an automatic powder feeding device, including a feeding bin 100 and an automatic feeding mechanism. Control the electromagnetic pneumatic butterfly valve that closes and opens the feeding channel.

[0045] The powder automatic feeding device in this embodiment automatically controls the opening of the material through hole through the electromagnetic pneumatic butterfly valve to realize the automatic feeding of the powder into the buffer tank 200, and then automatically closes the material through hole through the electromagnetic pneumatic butterfly valve, and then relies on the material in the buffer tank 200. The air pressure is adjusted to transport the powder to the feeding tank 2, and the automatic control of the powder feeding is realized as a whole.

[0046] In fact, the structure of the receiving bin 100 in the automatic powder feeding device of the present invention is not limited to the shape of a ci...

Abstract

The invention relates to an automatic powder feeding device and an environment-friendly cement mixing pile ash feeding system. The automatic powder feeding device includes a material receiving bin andan automatic material transmission mechanism; the automatic material transmission mechanism includes a buffer tank, a control valve, and a material feeding tank, the buffer tank and the material receiving bin are connected through the control valve, the buffer tank is located below the material receiving bin to receive a powder material flowing out of the discharging opening of the material receiving bin, the buffer tank and the material feeding tank are connected through a material conveying pipe, an air inlet pipe is arranged on the device wall of the buffer tank, a discharge opening is formed in the material feeding tank, the air inlet pipe is used for being connected with a high-pressure air source to automatically blow the powder material in the buffer tank into the material feedingtank. Compared with the existing way of conveying the powder material by a screw conveyor, low power consumption, high material feeding efficiency, small space occupation, and effective cost saving can be simultaneously achieve by the automatic powder feeding device.

Description

technical field [0001] The invention relates to an automatic powder feeding device and an environment-friendly cement mixing pile ash delivery system. Background technique [0002] The existing cement-soil mixing pile machine in my country adopts a conventional feeding device, and its device is as follows: figure 1 As shown, it includes a bulk cement storage tank 1, a screw conveyor 11, a universal head 12 connected to the feed end of the screw conveyor (commonly known as "auger") and a feeding tank 2 connected to the discharge end of the screw conveyor. The operation method of using a motor-driven screw conveyor to transport cement powder and other powders has the disadvantages of high power consumption, high cost, large volume, low feeding efficiency, cement powder is easy to enter the auger bearing, and the auger is stuck and the motor is burned. Normal construction cannot be guaranteed. Contents of the invention [0003] Based on this, it is necessary to provide an a...
