[0016] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0017] like Figures 1 to 6 As shown, a peristaltic gas-solid isolation feeding equipment includes a shell 1, a hopper 2 is installed on the top of the shell 1, the hopper 2 has an inverted cone silo 3, the bottom end of the silo is a first discharge port, and a distribution pipe 4 is provided on the side wall of the inverted cone silo 3, the bottom end of the distribution pipe 4 is a second discharge port.

[0018] An elastic hose and an extrusion mechanism for extruding the elastic hose are installed in the shell 1. Two elastic hoses are arranged side by side, namely a first elastic hose 5 and a second elastic hose 6. The top end of the first elastic hose 5 is connected to the first discharge port, and the top end of the second elastic hose 6 is connected to the second discharge port.

[0019] A delivery pipe 7 is installed at the bottom of the shell 1, and through holes are opened on the shell 1 corresponding to the two ends of the delivery pipe 7. The bottom ends of the first elastic hose 5 and the second elastic hose 6 are connected to the delivery pipe 7 through the gas-solid mixing chamber 8. The extrusion mechanism includes a reduction motor 9, a first rotating shaft 10, a second rotating shaft 11, a third rotating shaft 12 and a fourth rotating shaft 13. The first rotating shaft 10 and the second rotating shaft 11 as well as the third rotating shaft 12 and the fourth rotating shaft 13 are all installed on the inner wall of the shell 1 through a rotating shaft mounting plate 14, and the first rotating shaft 10, the second rotating shaft 11 and the third rotating shaft 12 are connected to the gas-solid mixing chamber 8. 12. The fourth rotating shaft 13 is correspondingly arranged on both sides of the first and second elastic hoses 5 and 6. Both ends of the first rotating shaft 10 and the second rotating shaft 11 are connected by a transmission chain 15, and three rolling wheels 16 are installed on the transmission chain 15 at equal intervals. Both ends of the third rotating shaft 12 and the fourth rotating shaft 13 are connected by a transmission chain 15, and three rolling wheels 16 are installed on the transmission chain 15 at equal intervals. One end of the first rotating shaft 10 is connected to the output end of the reduction motor 9, and the other end is installed with a driving gear 17. A driven gear 18 is installed at the end of the third rotating shaft 12 to mesh with the driving gear 17.

[0020] The rolling wheel 16 includes a wheel axle and a pressure wheel. Both ends of the wheel axle are fixed on the transmission chain 15, and the pressure wheel is rotatably mounted on the wheel axle. Since the pressure wheel can rotate freely, it is beneficial to reduce the wear of the first and second elastic hoses 5 and 6 and extend their service life.

[0021] In this embodiment, the gas-solid mixing chamber 8 comprises a front side plate 801, a rear side plate 802, a left side plate 803, a right side plate 804 and a top plate 805, a feed port connected to an elastic hose is provided on the top plate 805, the top plate 805 is connected to the conveying pipe 7 via the front side plate 801, the rear side plate 802, the left side plate 803 and the right side plate 804, and the front side plate 801, the rear side plate 802, the left side plate 803 and the right side plate 804 form a gas-solid mixing chamber, the front side plate 801 and the rear side plate 802 are both inclined inward from top to bottom, the left side plate 803 and the right side plate 804 are parallel to each other and inclined in the direction of material conveying. This structural design of the gas-solid mixing chamber 8 is, on the one hand, conducive to the material falling into the conveying pipe 7, and on the other hand, the width of the gas-solid mixing chamber is gradually reduced from top to bottom, and high-pressure gas is input into the conveying pipe 7 to prevent the material from returning to the gas-solid mixing chamber. The left plate 803 and the right plate 804 are inclined toward the material conveying direction, which is conducive to the high-pressure gas to smoothly carry out the material.

[0022] During operation, one end of the delivery pipe 7 is connected to a high-pressure gas source, and the other end is connected to a designated position. The material enters from the hopper 2, a portion of the material enters the first elastic hose 5 from the first discharge port, and the other portion of the material enters the second elastic hose 6 from the second discharge port through the distribution pipe 4. The reduction motor 9 works, driving the first rotating shaft 10 to rotate, thereby driving the transmission chain 15 to move, and the driving gear 17 drives the third rotating shaft 12 to rotate through the driven gear 18, thereby driving the transmission chain 15 to move, and both sides of the first elastic hose 5 and the second elastic hose 6 are squeezed by the rolling wheel 16 at the same time, and 1-2 groups of pressing wheels are always kept pressing on the first and second elastic hoses 5 and 6, forming 1-2 sealing lines, which have sufficient sealing performance, ensuring that the high-pressure gas at the lower end flows along the delivery pipe 7, thereby ensuring that the pressure inside the equipment is not exposed to the normal pressure environment, there is no loss of high-pressure gas, and the overall energy consumption is lower. As the transmission chain continues to move, the pressing wheels sequentially compress and push the materials in the first elastic hose and the second elastic hose downward to form a continuous feeding flow. At the same time, due to the closed nature of the first elastic hose and the second elastic hose, gas cannot enter or escape, thereby achieving gas-solid isolation.

[0023] Compared with the prior art, the utility model can unload a variety of materials and is suitable for continuous discharge of powdery, granular, flaky and fibrous materials.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
