Description

Technical Field

[0001] The utility model relates to the field of reactor silos, in particular to a gas pressure balancing device for a silo. Background Art

[0002] In the production process of sewage treatment agents, when conveying these raw materials to the reactor, air delivery is mostly used. The raw materials are transported to different reactor silos through various pipelines through air delivery devices for reaction as the same batch to produce products. The performance and quality of the products in the same batch of sewage treatment agents need to be the same or similar, and there should not be too much difference. The air pressure in the reactor silo will affect the reactor. Therefore, the environmental conditions in the silos of multiple reactors should be the same or similar, and there should not be too much difference. Ordinary reactor silos do not have the conditions to balance the air pressure with each other so that the air pressure reaches the same or similar conditions. The operation of adjusting the air pressure of a single reactor silo is cumbersome and prone to deviations.

DETAILED DESCRIPTION

[0019] The following is a further description of the present invention in conjunction with specific embodiments. These embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0020] See also Figures 1 to 2 This is the structural view of the utility model. Figure 1 A partial enlarged view at point A in the middle shows a silo air pressure balancing device, which is arranged on the silo upper cover 8. A silo body 9 is arranged at the lower end of the silo upper cover 8. The middle part of the silo upper cover 8 is connected to the feed pipe. The silo body 9 is arranged above the reactor to feed the reactor. The number of silo bodies 9 and silo upper covers 8 is not less than two.

[0021] An air pressure detection device 1 is connected to the inner side of the upper side wall of the silo cover 8 through a nut. The air pressure detection device 1 is used to detect the air pressure condition in the silo in real time. A branch pipe 6 is connected to the inner side of the upper side wall of the silo cover 8 through a connecting nut 10. A solenoid valve 7 is arranged on the branch pipe 6. A joint is connected to the end of the branch pipe 6. Adjacent joints are connected through a connecting pipe 4. The lower end of the branch pipe 6 passes through the silo cover 8 and the end is connected to an internal module 2. The passage of the branch pipe 6 can be opened or closed by the solenoid valve 7, so as to control the connectivity between the space inside the silo cover 8 and the connecting pipe 4. When the solenoid valve 7 on two or more branch pipes 6 is opened, the air pressure inside two or more silos can be balanced. The target silo for balancing the air pressure can be selected by selecting the opened solenoid valve 7.

[0022] In order to facilitate the control of electronic components and the control of air pressure balancing operations, a controller is also included. A control cabinet is arranged on the outside of the controller, and a power module is arranged on the inside of the control cabinet. The power module is electrically connected to the controller through a wire, and the controller is powered by the power module. The power module is connected to an external power supply. The controller is electrically connected to the solenoid valve 7 and the gas detection device through wires respectively. The solenoid valve 7 and the gas detection device are powered by the controller. The controller receives signal data from the gas detection device to judge the air pressure value inside each silo. If the difference in air pressure value is too large, the solenoid valve 7 connected to the corresponding silo will be opened, and the solenoid valves 7 of other silos to be balanced will be opened at the same time, so that a channel is established between multiple silos, and gas can flow to balance the air pressure. After the balance is completed, the solenoid valve 7 can be closed.

[0023] The solenoid valve 7 can also be selected to be normally open to always maintain the connection state between the silos.

[0024] The function of the inner module is to balance the air pressure while preventing excessive circulation of materials. Because the material is loaded by air delivery, the powder will flow with the wind direction. If the solenoid valve 7 is opened and multiple silos are connected, the powder may flow through the branch pipe 6 and the connecting pipe 4, or accumulate too much in the horizontal section of the pipe, affecting the normal production steps. The internal module 2 includes a connecting tube 11, and the upper end of the connecting tube 11 is connected to a connecting sleeve 13. The circumferential surface of the connecting sleeve 13 is connected to the branch pipe 6 through a connecting bolt 14. The lower end of the connecting tube 11 is connected to the wind shield 12 and is blocked by the wind shield 12. The circumferential surface of the connecting tube 11 is provided with an installation bolt. A mounting opening 16, the side wall of which is provided with an inwardly recessed slot 15, and in order to reduce the material entering the pipeline, a filter screen 17 is further provided on the inner side of the slot 15, and the material is filtered through the filter screen 17, and in order to prevent the material on the filter screen 17 from blocking the filter screen 17, a micro vibration motor 18 is further provided on the upper side wall of the connecting tube 11, and the micro vibration motor 18 is connected to the controller through a wire, and most of the material on the filter screen 17 can be shaken off by the vibration action of the micro vibration motor 18, and in order to seal the joint between the connecting sleeve 13 and the branch pipe 6, a sealing sleeve 19 is provided between the connecting sleeve 13 and the branch pipe 6.

[0025] The wind shield 12 is a conical structure with the tip facing upwards, and the wind shield 12 can effectively block the rising airflow and raised materials from below.

[0026] In order to reduce the amount of material entering the pipeline, the installation opening 16 is further arranged to open toward an end away from the feed pipeline.

[0027] The utility model provides an internal module 2 inside the silo, cooperates with the interconnected pipes, solenoid valve 7, and the air pressure detection device 1 provided on the silo, coordinates and adjusts the air pressure balance operation between multiple silos, and realizes the function of balancing the internal air pressure of multiple silos, thereby reducing product quality differences and improving work efficiency.
