Description

Technical Field

[0001] This utility model relates to the technical field of pneumatic conveying, and in particular to the technical field of a silo pump with a discharge tee that can supplement airflow. Background Technology

[0002] The patent application (application number) CN202222009356.4 describes a suspended installation structure for an economizer ash conveying silo pump, which includes an ash hopper, a silo pump, an ash conveying pipe, and an expansion joint. The silo pump is connected to the ash hopper, and the ash conveying pipe is connected to the outlet of the silo pump and fixedly installed on the boiler steel frame and stationary relative to the ground. When conveying ash, the material entering the outlet of the silo pump is only conveyed by the airflow input at the front port of the silo pump outlet. Since the outlet of this silo pump is a gas-ash mixture, the exhaust speed is slow, the gas and solid phases are uneven, and the material is prone to accumulate and cause pipe blockage, especially when the material particles are large (the ash collected in the economizer ash hopper). Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a silo pump with a discharge tee that can supplement the airflow, which can reduce the problem of pipe blockage caused by material accumulation and reduce wear on the discharge tee and pipes.

[0004] To achieve the above objectives, this utility model proposes a silo pump with a discharge tee capable of supplemental gasification, comprising a silo body and a discharge tee. The discharge tee consists of a horizontal pipe and a vertical pipe vertically mounted on and connected to the horizontal pipe. The upper end of the vertical pipe is connected to the lower end of the silo body. Supplemental gasification ports are provided on both the front and rear sides of the horizontal pipe and are connected to it. A purge port is provided at the lower end of the horizontal pipe. A plug valve is provided on the purge port. Both the supplemental gasification port and the plug valve are connected to the main air inlet pipe.

[0005] Preferably, the thrombus valve is connected to the main air intake pipe via a purge hose.

[0006] Preferably, the intake manifold is provided with a supplementary air manifold connected thereto. The output end of the supplementary air manifold is connected to the input end of two supplementary air plastic hoses through a supplementary air tee connector. The output ends of the two supplementary air plastic hoses are connected to two supplementary air flow ports through a diaphragm check valve I. The supplementary air manifold is provided with a supplementary air ball valve.

[0007] Preferably, both the output end of the air replenishment tee and the input end of the diaphragm check valve I are equipped with quick-connect air hoses that mate with the air replenishment plastic hose.

[0008] Preferably, the intake manifold is provided with a jetting manifold connected to it. The output end of the jetting manifold is connected to the input end of three jetting plastic hoses through a four-way connector. The output ends of the three jetting plastic hoses are connected to three nozzles through a diaphragm check valve II. The three nozzles are arranged in a circumferentially spaced manner on the lower circumferential surface of the chamber.

[0009] Preferably, the main jet pipe is equipped with a jet ball valve.

[0010] Preferably, the system also includes a main gas supply pipe, which is connected to the input end of a gas supply tee connector via a metal hose. The two output ends of the gas supply tee connector are respectively connected to the main gas inlet pipe and the pressurization pipeline. The pressurization pipeline is connected to the air inlet on the upper end of the chamber. The pressurization pipeline is equipped with a pressurization ball valve and a diaphragm check valve III.

[0011] Preferably, the intake manifold is equipped with an intake ball valve.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a gasification port connected to both the front and rear sides of a horizontal pipe, and a purge port at the lower end of the horizontal pipe. A valve is installed on the purge port, and both the gasification port and the valve are connected to the main air inlet. The gas entering through the gasification port fluidizes the material inside the horizontal pipe, allowing the material to operate in its optimal fluidized state, reducing the problem of pipe blockage caused by material accumulation, and improving the reliability of conveying. Since the dust collected in the economizer ash hopper contains large particles, it often accumulates and causes pipe blockage after a period of conveying. When the pressure inside the pipe increases due to ash blockage, the valve automatically opens to blow air through the discharge tee and pipe, avoiding accelerated wear of the discharge tee and pipe caused by long-term high-flow-rate gas conveying. Compared with existing technologies, this invention reduces the problem of pipe blockage caused by material accumulation and reduces wear on the discharge tee and pipe.

Detailed Implementation

[0017] See Figure 1 , Figure 2 This utility model discloses a silo pump with a discharge tee for supplementary gas aeration, comprising a silo body 1 and a discharge tee 2. The discharge tee 2 is composed of a horizontal pipe 21 and a vertical pipe 22 vertically arranged on and connected to the horizontal pipe 21. The upper end of the vertical pipe 22 is connected to the lower end of the silo body 1. Supplementary gas aeration ports 3 are provided on both the front and rear sides of the horizontal pipe 21 and are connected to it. A purge port 4 is provided at the lower end of the horizontal pipe 21. A plug valve 5 is provided on the purge port 4. Both the supplementary gas aeration port 3 and the plug valve 5 are connected to the main air inlet pipe 6.

[0018] The thrombus valve 5 is connected to the intake main pipe 6 via the purge hose 7.

[0019] The intake manifold 6 is equipped with a supplementary air manifold 9 connected to it. The output end of the supplementary air manifold 9 is connected to the input end of two supplementary air plastic hoses 11 through a supplementary air tee connector 10. The output ends of the two supplementary air plastic hoses 11 are connected to two supplementary air flow ports 3 through a diaphragm check valve I8. The supplementary air manifold 9 is equipped with a supplementary air ball valve 12.

[0020] Both the output end of the air replenishment tee connector 10 and the input end of the diaphragm check valve I8 are equipped with quick-connect air hoses 13 that mate with the air replenishment plastic hose 11.

[0021] The intake manifold 6 is equipped with a jetting manifold 14 connected to it. The output end of the jetting manifold 14 is connected to the input end of three jetting plastic hoses 16 through a four-way connector 15. The output ends of the three jetting plastic hoses 16 are connected to three nozzles 18 through a diaphragm check valve II 17. The three nozzles 18 are arranged in a circumferential pattern on the lower circumferential surface of the chamber 1.

[0022] The main jet pipe 14 is equipped with a jet ball valve 19.

[0023] It also includes a gas supply main pipe 110, which is connected to the input end of a gas supply tee connector 112 via a metal hose 111. The two output ends of the gas supply tee connector 112 are connected to the air inlet main pipe 6 and the pressure application pipeline 113, respectively. The pressure application pipeline 113 is connected to the air inlet 117 on the upper end of the chamber 1. The pressure application pipeline 113 is equipped with a pressure ball valve 114 and a diaphragm check valve III 115.

[0024] The intake manifold 6 is equipped with an intake ball valve 116.

[0025] The working process of this utility model:

[0026] In operation, the gas in this utility model is a discharge tee-type gas-puffing silo pump. When the inlet gas valve 116 and the gas-puffing valve 12 are opened, the gas passes sequentially through the gas supply main pipe 110, the metal hose 111, the inlet gas main pipe 6, the gas-puffing main pipe 9, the gas-puffing tee connector 10, the gas-puffing plastic hose 11, the diaphragm check valve 18, and the gas-puffing port 3, and then enters the horizontal pipe 21 to gasify the material inside.

[0027] When the ball valve 19 is opened, the gas passes through the main jet pipe 14, the four-way connector 15, the jet plastic hose 16 and the nozzle 18 in sequence, and then is injected into the chamber 1. During the discharge process, the gas is sprayed out through the nozzle, so that the material inside the chamber is in a fluidized and rotating state, which makes it easier for the material to be discharged from the chamber and less likely to cause blockage.

[0028] When the pressure inside the pipe and discharge tee 2 rises due to ash blockage, the plug valve 5 automatically opens to blow air through the discharge tee and pipe.

[0029] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
