A pneumatic conveying feeder and conveying pipe connection structure

Abstract

The invention discloses a pneumatic conveying feeder, which comprises a middle cylinder, an upper flange, a lower flange, an impeller and a transmission device; at least two feeding ports are arranged on the upper flange, and the feeding port is connected to the The number of feed ports is the same and the discharge ports and feed ports are arranged in a staggered manner; the utilization rate of equipment space is improved, thereby improving the feeding capacity of a single device; through the position corresponding to each discharge port on the lower surface of the upper flange There is a groove-shaped air distribution chamber at the center, which changes the injection mode, thereby improving the injection capacity and injection concentration of a single device with the same caliber to the material, and reducing the operating cost of the equipment. The invention also discloses a connection structure of conveying pipes. By changing the connection relationship between the conveying pipes, not only can one feeder spray to one reactor according to the traditional method, but also can ensure the accuracy of the flow rate of the sprayed material. It can realize one feeder spraying two reactors, thus saving cost for users.

Description

technical field [0001] The invention belongs to the field of bulk material pneumatic conveying equipment, and in particular relates to a pneumatic conveying feeder and a conveying pipe connection structure. Background technique [0002] In industries such as metallurgy, pneumatic conveying of bulk materials has high requirements on conveying capacity and conveying precision. Usually, vertical rotary feeders are used for conveying, which can achieve higher conveying precision than ordinary fluidized pressurized methods. The published Chinese patents of vertical feeders that are often used in engineering are: 201220205422.9, 201020619756.1, 201220673793.X, 201320480948.2, 201620306364.7, 201620622572.8. Each port is one each, and adopts the staggered arrangement of 180° to form a single-channel material conveying mode in the feeder. The investment cost is high; in order to improve the feeding capacity of a single outlet, the outlet opening is large, resulting in a large waste...

The published Chinese patents of vertical feeders that are often used in engineering are: 201220205422.9, 201020619756.1, 201220673793.X, 201320480948.2, 201620306364.7, 201620622572.8. Each port is one each, and adopts the staggered arrangement of 180° to form a single-channel material conveying mode in the feeder. The investment cost is high; in order to improve the feeding capacity of a single outlet, the outlet opening is large, resulting in a large waste of blowing gas, and the user's operating cost is high; the difference between the inlet and outlet of the single-channel structure is 180°, resulting in the discharge of the blowing tank Eccentric, unable to form a stable overall blanking; the uneven structure of the blowing port also causes a certain amount of waste of air consumption

[0003] Published patents 201320485328.8 and 201310346847.0 show that there are multiple feed ports and discharge ports, but the shape of the feed ports and the shape of the blades or the conveying method of the material in the feeder are different from the traditional vertical rotary feeder. Different, its solution is mainly to solve the accuracy problem of the traditional fluidized pressurization method. Due to the limitation of the shape of the inlet and outlet, the shape of the blade, and the setting of the conveying method, compared with the ordinary vertical feeder, it is more expensive in terms of equipment capacity and equipment space. The utilization rate has not been improved, and the supporting injection delivery method described is relatively simple

[0004] The published patent 201210217828.3 is a double-channel star feeder, which is quite different from the traditional vertical rotary feeder in the feeding and discharging form and working mode. It is mainly in the form of a horizontal star valve. According to public information, due to its Inherent characteristics, this form is rarely used in occasions with high precision requirements
