Description

TECHNICAL FIELD

[0001] The utility model relates to the field of grain depot comprehensive valley cold ventilation, especially relates to the linkage valley cold silo ventilation system of granary. BACKGROUND

[0002] As a modern grain storage facility, the ventilation system of vertical silos encounters many systematic challenges in actual operation. The solution to these problems relies on in-depth analysis of process layout and equipment configuration. First, spatial limitations and process design defects are one of the main problems faced by vertical silo groups. Due to the design of dense arrangement of vertical silo groups, the operation space of the conical structure at the bottom of the silo is extremely limited, usually less than 2 meters.

[0003] Second, equipment duplication and efficiency loss are also a major problem in the current operation mode. The current operation mode requires a "one silo one machine" configuration, which means that each silo needs to be equipped with a 5.5 kilowatt axial flow fan or a 15 kilowatt centrifugal fan. However, this configuration results in a high idle rate of equipment of more than 60%. In the case of simultaneous operation of multiple silos, the weight of the grain cooler exceeds 200 kilograms, and the equipment transfer time accounts for 30% of the total operation time. In addition, the connection of soft wind pipe has a wind pressure loss of 20-30%, and the interface air leakage rate is generally more than 5%.

[0004] The efficiency bottleneck of man-machine cooperation is also a problem that cannot be ignored. The operation process involves equipment transportation, pipe connection, parameter adjustment and other links. Single silo ventilation requires 3 people to operate cooperatively, including equipment positioning, pipe connection, grain condition monitoring, etc., and the per capita operation area is only 1.5 square meters. During the ventilation period, 6-8 temperature measuring points need to be continuously monitored, and the data collection frequency reaches 2 times per hour. In emergency disposal, the equipment switching response time exceeds 15 minutes.

[0005] Finally, the superposition of energy consumption and safety hazards cannot be ignored. The traditional decentralized ventilation mode leads to a ventilation power consumption of 0.8-1.2 kilowatt hours per ton of grain, which is 40% higher than that of centralized air supply system. The dense stacking of equipment increases the carbon dioxide concentration over limit rate by 15%. Soft tube kinking, falling and other faults may also cause the risk of dust cloud concentration exceeding the standard.

[0006] Current data shows that the ton of grain storage cost of vertical silo group using traditional decentralized ventilation system is 22-35% higher than that of modern centralized ventilation system, and the operation accident rate is increased by 3 times. Therefore, it is urgent to reconstruct the air duct and develop an intelligent control system to solve the above problems.

The fixing mode not expressed in the text can be any one of the fixing modes such as screw fixing, bolt fixing or glue bonding.

[0055] Embodiment one: in combination with all the drawings; the grain bin linkage grain cooling silo ventilation system, characterized in that,

[0056] The grain cooling silo ventilation system is arranged below the bin body, and the bin body comprises a silo and a clamping bin;

[0057] The clamping bin is formed by clamping the side wall of the silo;

[0058] The silo and the clamping bin below both comprise a vertical pipe 4, and the vertical pipe 4 is part of an air pipe;

[0059] The air pipe comprises a main ventilation pipe 5, and the main ventilation pipe 5 is connected with multiple annular pipes 6; each annular pipe 6 branches into multiple vertical pipes 4 upwards; the annular pipe 6 is an arc-shaped pipe, and the two ends of the annular pipe 6 are closed by a closing plate 3.

[0060] The vertical pipe 4 can be inserted into the bin body;

[0061] The mouth of the main ventilation pipe 5 is a main air port 8, and the main air port 8 is connected to the grain cooler. The essential technical effect and implementation process of the technical solution in the place and the basic function are as follows:

[0062] The vertical silo group is composed of 16 single silos with a diameter of 12 meters and 9 clamping bins Figure 3 Each single bin has a designed bin bottom ventilation pipe for ventilation cooling and circulating fumigation.

[0063] The ventilation ports of multiple silos and adjacent clamping bins are connected by a ventilation pipe to centrally supply air, and the size of the air supply main pipe is obtained according to the air supply professional calculation. In most cases, the grain cooler is used to cool the silo, and the air supply temperature of the grain cooler is about 12-20℃. In order to ensure that the air supply pipe does not condense water, the outer wall of the air supply pipe is wrapped with a 50mm thick heat preservation material. The inlet of the main ventilation pipe is led out of the building window, so that the ventilation and cooling of each connected silo can be realized through the pipe outside the window. The use quantity of ventilation equipment is reduced, and the movement of ventilation equipment in the narrow space in the bin is avoided. The labor and material costs are reduced.

[0064] After the above modification, the ventilation and cooling work of the whole silo group can be completed by a few people outside the silo. The staff will move the grain cooler or ventilation equipment to the main air inlet at the outside window, connect the equipment with the air port, select any silo number that needs ventilation, open the electric sealing valve when the green light shows that it is in place, and then open the grain cooler or ventilation equipment. This greatly saves manpower and improves the utilization rate of ventilation equipment.

[0065] The bottom space is wider, and ventilation can be done outside the window, solving the problem of space congestion.

[0066] And multiple sets of ventilation pipes are arranged vertically, making ventilation more uniform.

[0067] Multiple silos can share one fan; various wind forces can be scientifically allocated; meanwhile, manpower is saved, greatly reducing the workload.

[0068] The silo and the sandwiched silo can store more grain.

[0069] Example Two: As a further improved scheme or parallel scheme or alternative independent scheme, the outer wall of the air pipe is wrapped with 50mm thick insulation material. The essential technical effect and its implementation process of the technical solution in this place are as follows: the insulation material can maintain the temperature of the cold air. The insulation material can be made of any material.

[0070] Example Three: As a further improved scheme or parallel scheme or alternative independent scheme, the inlet of the main ventilation pipe 5, i.e. the main air port 8, leads out of the building window, which can realize ventilation and cooling of each connected silo through the pipe outside the window. The essential technical effect and its implementation process of the technical solution in this place are as follows: therefore, ventilation can be done outside the window.

[0071] Example Four: As a further improved scheme or parallel scheme or alternative independent scheme, the air inlet of each silo and sandwiched silo is arranged with an explosion-proof electric sealing valve. The essential technical effect and its implementation process of the technical solution in this place are as follows: an explosion-proof electric sealing air valve is installed at the air inlet of each silo. Considering the actual situation of grain storage, fumigation and air conditioning operations need to be performed in the silo from time to time, in order to ensure that the adjacent silos are not affected by fumigation and air conditioning operations and to facilitate operation, an explosion-proof electric sealing valve is installed at the air inlet of each silo. When ventilation and cooling are needed, open the air valve; when it is not needed, close the air valve according to the needs.

[0072] Embodiment five: as a further improvable scheme or parallel scheme or alternative independent scheme, the silo contains four rows and four columns, and the clamped gaps constitute nine clamping silos. The essential technical effect and its implementation process of the technical scheme are as follows: the silo type arrangement can be replaced, which is within the protection scope of the patent.

[0073] Embodiment six: as a further improvable scheme or parallel scheme or alternative independent scheme, the lower parts of the silo and the clamping silo are conical mechanisms, and the lower parts of the silo and the clamping silo each contain an annular pipe 6. The essential technical effect and its implementation process of the technical scheme are as follows: air can be divided into each silo.

[0074] Embodiment seven: as a further improvable scheme or parallel scheme or alternative independent scheme, a control box is further included, which can be used to control the explosion-proof electric sealing valve; the control box is provided with an on-off switch of each explosion-proof electric air valve, and further includes an indicator lamp arranged on the control box. The essential technical effect and its implementation process of the technical scheme are as follows: because the number of explosion-proof sealing valves is large, and the installation position is limited on site, it is not convenient to manually open and close the sealing valve, so a control box is needed to control the explosion-proof electric sealing valve. The control box is provided with an on-off switch of each explosion-proof electric air valve. At the same time, in order to prevent misoperation and facilitate identification, there is a green light indication of opening to position after each valve is started, and a red light indication of closing to position after each valve is closed; no indicator light is displayed during the opening and closing process.

[0075] The above effects independently exist, and a set of structures can also be used to achieve the combination of the above results.

[0076] It should be noted that the modules of the patent are integrations of modules of the prior art, and do not involve new modules. Even if part of the modules use programs, the programs are undoubtedly known programs.

[0077] It should be noted that the multiple schemes provided by the patent include basic schemes, which are independent of each other and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects.

[0078] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made without departing from the spirit and scope of the utility model. These changes and improvements all fall within the scope of protection.
