[0001] This utility model relates to the field of material conveying equipment technology, specifically to an alternative fuel material distribution and conveying system. Background Technology

[0002] In recent years, with the rapid development of my country's economy, cement consumption has also grown rapidly. A few years ago, most cement companies did not have a strong need or sense of urgency for carbon emission reduction and the use of alternative fuels. However, in recent years, cement prices have fallen, putting significant pressure on the production costs of cement producers.

[0003] Under the dual-carbon goals, the cement industry is about to be included in the carbon trading system. In the future, carbon dioxide emission rights will require more financial support, which will inevitably place higher demands on cement companies' green and low-carbon technologies, forcing them to eliminate outdated equipment and production capacity while reducing investment costs. Therefore, most cement companies have begun to actively use alternative fuels. However, the current lack of unified standards for alternative fuels among cement companies results in a complex and varied range of alternative fuels, necessitating a highly adaptable material distribution and conveying equipment.

[0034] With reference to the accompanying drawings of the embodiments of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below.

[0035] Example: Please refer to the appendix Figure 1-3 This utility model provides a technical solution: an alternative fuel distribution and conveying system, comprising:

[0036] Buffer bin 1, which is connected to the feeding equipment;

[0037] The dual-outlet conveying mechanism 6 is located directly below the buffer bin 1, and the inlet of the dual-outlet conveying mechanism 6 is connected to the bottom circular opening of the buffer bin 1. The dual-outlet conveying mechanism 6 has two outlets, which are connected to two bins respectively.

[0038] Multiple arch-breaking mechanisms 2 are provided and evenly installed on the buffer chamber 1. Each arch-breaking mechanism 2 can stir and loosen the material accumulated on the walls of the buffer chamber 1.

[0039] And an automatic sprinkler system, which is installed on the inner top of the buffer chamber 1. The automatic sprinkler system is controlled by the temperature monitoring system 4 to spray and extinguish the fire on the burning materials in the buffer chamber 1.

[0040] The dual-outlet conveying mechanism 6 consists of two parallel but opposing screw conveyors, both of which are located on the same horizontal plane.

[0041] In this embodiment, the screw conveyor includes:

[0042] Conveyor box 11;

[0043] The variable pitch screw blade 9 is rotatably installed inside the cylindrical cavity of the conveying box 11;

[0044] The bearing housing 12 is fixed to one side of the conveyor box 11, and a rotating shaft connected to the variable pitch screw blade 9 is rotatably installed inside the bearing housing 12.

[0045] The variable frequency motor 8 is fixed on the bearing housing 12 and drives the rotating shaft to rotate;

[0046] It should be noted that the variable frequency motor can adjust the screw speed according to the required amount of material at the rear, and can also automatically reverse according to the operating conditions.

[0047] And discharge hopper 13, which is installed at the discharge port of conveyor box 11.

[0048] In this embodiment, the pitch of the variable pitch screw blade 9 increases gradually along its discharge direction, which can reduce the resistance to material conveying.

[0049] In this embodiment, the part connecting the buffer chamber and the outlet end of the conveyor box 11 is an arc-shaped structure;

[0050] It should be noted that the arc design can reduce the pushing resistance of the double-outlet conveying screw when there is a certain material layer thickness in the buffer bin 1.

[0051] In this embodiment, the arch-breaking mechanism 2 is composed of a transmission gearbox 201, an arch-breaking motor 202, and an arch-breaking assembly. The transmission gearbox 201 is fixed on the side wall of the buffer chamber 1, and the arch-breaking motor 202 is fixed on the top of the transmission gearbox 201. The driving end of the arch-breaking motor 202 is connected to the drive gear inside the transmission gearbox 201.

[0052] The arch-breaking component is installed inside the buffer chamber 1 and is connected to the driven gear in the transmission gearbox 201 by a coupling. The arch-breaking component can stir and loosen the material accumulated on the chamber wall, so that the material inside the chamber will not be emptied.

[0053] In this embodiment, the automatic sprinkler system includes:

[0054] Multiple atomizing nozzles 5 are provided and are evenly installed on the inner top wall of the buffer chamber 1.

[0055] It should be added that the number of atomizing nozzles 5 can be set according to the size of the buffer chamber 1;

[0056] And a water injection pipe 16, one end of which is connected to each atomizing nozzle 5, and the other end of the water injection pipe 16 is connected to the water supply equipment.

[0057] The water injection pipe 16 is equipped with a pressure regulating valve 15 and a solenoid valve 14 in sequence along its water injection direction.

[0058] In this embodiment, the temperature monitoring system 4 includes a screw-type temperature sensor and a spark detector;

[0059] It should be noted that the temperature monitoring system 4 can monitor the temperature inside the hopper and whether sparks are generated. If the temperature is higher than the set temperature value or sparks are generated, an alarm signal will be issued and the automatic spray system will be controlled to spray water to cool down the hopper.

[0060] In this embodiment, a radar level gauge 3 is installed on the top of the buffer bin 1 to monitor the material level inside the buffer bin 1, reflecting the material level height inside the bin and adjusting the feeding speed.

[0061] In this embodiment, a maintenance observation door 10 and a burst valve 7 are also provided on the side wall of the buffer chamber 1.

[0062] Among them, the explosion relief valve 7 is used to deal with possible dust flash explosions, and the inspection and observation door 10 is used to inspect the interior of the buffer chamber 1.

[0063] In practice, alternative fuel is fed into the buffer bin 1 of the distribution system by the feeding equipment. The buffer bin 1 can store a portion of the material to maintain the balance and stability of the distribution system. The material level in the buffer bin 1 can be monitored by the radar level gauge 3. If the material level exceeds the set height, the level gauge will automatically send a signal to the control system to reduce the amount of material coming in front and prevent the buffer bin 1 from being full. If the material level is lower than the set height, the level gauge will automatically send a signal to the control system to increase the amount of material coming in front and prevent the buffer bin 1 from being empty. That is, the radar level gauge can maintain the dynamic balance of the material in the buffer bin 1.

[0064] If only one line needs to run, the material on the other side may accumulate. At this time, the arch-breaking motor 2 set on the silo wall can be turned on so that the material in the non-moving spiral section will not accumulate too much. The material in the buffer silo 1 can be transported to the designated downstream silo through the two discharge ports of the double discharge port conveying mechanism 6 below, and thus enter the designated feeding point.

[0065] If the temperature inside the buffer chamber exceeds the set value or sparks are generated during the above process, there may be a risk of fire. In this case, the solenoid valve of the automatic sprinkler system can be opened by the control system to spray water into the buffer chamber 1 through the atomizing nozzle to cool it down.

[0066] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
