Description

Technical Field

[0001] This utility model relates to the field of fertilizer production and conveying technology, and in particular to an energy-saving material conveying device for a functional fertilizer energy-saving production line. Background Technology

[0002] Functional fertilizers are fertilizers with specific functions that can meet the specific growth needs of crops or improve the soil environment. They are based on traditional fertilizers, with the addition of special ingredients or special processing to give them functions beyond providing the nutrients needed by plants. For example, some functional fertilizers add microbial communities to improve the soil microbial environment and enhance soil fertility; others add trace elements to specifically supplement nutrients that crops are prone to lacking during growth. In the production process of functional fertilizers, material transportation is a crucial step.

[0003] Currently, various material conveying devices exist on the market, such as the energy-saving compound fertilizer finished product conveying and cooling device disclosed in Chinese Patent Publication No. CN220038892U. This device includes a conveyor frame, with support legs fixedly connected to the bottom surface of the conveyor frame. A conveyor is installed inside the conveyor frame, and a shielding frame is fixedly connected to the top of the conveyor frame. Shielding plates are fixedly connected to both the left and right sides of the inner cavity of the shielding frame. An exhaust device is installed on the left side of the top of the shielding plate. Cooling windows are opened at the center and right side of the top surface of the shielding frame, and cooling fans are installed inside the cooling windows. T-shaped slots are opened on the front and rear sides of the bottom right side of the inner cavity of the conveyor frame. This utility model, through the combined use of a conveying pipe, exhaust fan, L-shaped heat absorption pipe, distribution plate, heat absorption plate, distribution pipe, and heat absorption holes, has the advantage of collecting the heat energy volatilized from the compound fertilizer. The heat energy is not directly discharged into the external environment, making full use of the heat energy and contributing to the energy-saving operation of the equipment.

[0004] However, the device still has shortcomings: it is inadequate in handling dust and fine materials. The device is not equipped with a dedicated dust collection component. When the scraper cleans the material on the belt surface, a large amount of dust and fine materials are generated. These substances are easy to accumulate inside the device, which not only affects the cleaning effect, but may also enter the equipment and cause wear on components such as conveyors and exhaust fans, reducing the service life of the equipment. Therefore, we propose a material conveying energy-saving device for a functional fertilizer energy-saving production line. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving material conveying device for a functional fertilizer energy-saving production line, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An energy-saving material conveying device for a functional fertilizer energy-saving production line includes a conveyor frame. The inner cavity of the conveyor frame is equipped with a conveyor for conveying functional fertilizer. A shielding frame is fixedly connected to the top of the conveyor frame. Shielding plates are fixedly connected to both the left and right sides of the inner cavity of the shielding frame. An exhaust assembly for collecting the heat energy from fertilizer volatilization is installed on one side of the top of the shielding frame. A cleaning assembly is provided on the other side of the bottom of the conveyor frame. The cleaning assembly is used to automatically clean the conveyor belt on the surface of the conveyor to ensure conveying efficiency and reduce energy consumption.

[0008] As a preferred embodiment of this utility model, the exhaust assembly includes an exhaust fan, a connecting pipe is provided between the exhaust fan and the inner cavity of the shielding frame, and a conveying pipe connected to external fertilizer production equipment is provided at the output end of the exhaust fan.

[0009] As a preferred embodiment of this utility model, multiple cooling fans are provided on the other side of the top of the shielding frame for heat dissipation and cooling of the functional fertilizer.

[0010] As a preferred embodiment of this utility model, the cleaning component includes a through slot at the bottom of the conveyor frame, and a cleaning box is fixedly connected to the bottom of the conveyor frame and around the through slot.

[0011] As a preferred embodiment of this utility model, the cleaning box is provided with a rotating shaft, a cleaning roller is sleeved on the rotating shaft, a plurality of connecting plates are arranged around the outer surface of the cleaning roller, and a cleaning brush is connected to the end of each of the plurality of connecting plates. A drive motor is bolted to the back of the cleaning box, and its output end is connected to the rotating shaft for transmission.

[0012] As a preferred embodiment of this utility model, a collection box is fixedly connected to the bottom of the cleaning box, the inner cavity of the cleaning box and the collection box are connected, a protective shell is provided on the front of the collection box, a filter screen is provided in the pipe opening connecting the inner cavity of the collection box and the protective shell, and an opening and closing door is hinged to the back of the collection box.

[0013] As a preferred embodiment of this utility model, a dust collection motor is provided on the front of the protective housing, and a fan blade is connected to the output end of the dust collection motor. Multiple ventilation slots are provided on both sides of the front of the protective housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, a cleaning assembly incorporates a vacuum motor, fan blades, ventilation slots, a filter screen, and a collection box. When the vacuum motor drives the fan blades to rotate, the ventilation slots connect with the outside environment to create airflow circulation. This generates negative pressure suction within the protective housing, drawing in dust and fine materials from the cleaning chamber. These materials are then intercepted by the filter screen and collected in the collection box, while the gas is discharged to the outside through the ventilation slots. This design not only ensures that the vacuum motor and fan blades continuously generate stable suction, maintaining the vacuuming effect within the cleaning chamber, but also prevents dust and materials from accumulating inside the cleaning chamber and interfering with the cleaning operation. It also prevents dust from escaping into the production environment, achieving the dual benefits of environmental purification and stable equipment operation. Furthermore, the coordinated use of the cleaning chamber, rotating shaft, cleaning rollers, and cleaning brushes enables continuous and efficient cleaning of the conveyor belt, removing attached materials and reducing the increased running resistance caused by material accumulation on the conveyor belt surface, thus ensuring conveying efficiency.

[0026] Example

[0027] like Figure 1-5As shown, this utility model provides a technical solution: an energy-saving material conveying device for a functional fertilizer energy-saving production line, including a conveyor frame 1, a conveyor 2 for conveying functional fertilizer installed in the inner cavity of the conveyor frame 1, a shielding frame 3 fixedly connected to the top of the conveyor frame 1, shielding plates 301 fixedly connected to the left and right sides of the inner cavity of the shielding frame 3, an exhaust component 4 for collecting the volatile heat energy of fertilizer installed on one side of the top of the shielding frame 3, and a cleaning component 6 provided on the other side of the bottom of the conveyor frame 1. The cleaning component 6 is used to automatically clean the conveyor belt on the surface of the conveyor 2 to ensure conveying efficiency and reduce energy consumption. The conveyor 2 is responsible for conveying materials. The shielding frame 3 and the shielding plates 301 can form a relatively closed space to reduce the loss of fertilizer heat energy and external interference. The exhaust component 4 collects the volatile heat energy of fertilizer to avoid heat energy waste, realize energy recovery and utilization, and reduce the energy consumption of the production line. The cleaning component 6 automatically cleans the conveyor belt to prevent material adhesion from affecting the conveying efficiency, reduce the increase in energy consumption caused by the increase in conveyor belt resistance, and ensure efficient and energy-saving operation of the conveying process.

[0028] The exhaust assembly 4 includes an exhaust fan 401. A connecting pipe 402 is provided between the exhaust fan 401 and the inner cavity of the shielding frame 3. The output end of the exhaust fan 401 is connected to a conveying pipe 403 that connects to external fertilizer production equipment. The exhaust fan 401 draws in the mixture of heat energy generated by fertilizer volatilization in the shielding frame 3 and air through the connecting pipe 402, and conveys it to the external fertilizer production equipment through the conveying pipe 403, realizing the secondary utilization of heat energy, such as for preheating raw materials, effectively reducing energy consumption and improving energy utilization efficiency.

[0029] Multiple cooling fans 5 are provided on the other side of the top of the shielding frame 3 to dissipate heat and cool down the functional fertilizer. The multiple cooling fans 5 can flexibly adjust their speed and working status according to the temperature of the functional fertilizer and the ambient temperature to dissipate heat and cool down the fertilizer, ensuring that the fertilizer is transported at a suitable temperature, avoiding changes in fertilizer composition due to excessive temperature, affecting product quality, and ensuring the stability of the transport process.

[0030] The cleaning component 6 includes a through slot 601 at the bottom of the conveyor frame 1, and a cleaning box 602 is fixedly connected to the bottom of the conveyor frame 1 and around the through slot 601. The through slot 601 provides a channel for cleaning the conveyor belt, allowing the cleaning component 6 to contact the conveyor belt for cleaning operations. The cleaning box 602 forms a closed cleaning space, confining the materials and dust generated during the cleaning process inside the box, preventing them from splashing into the production environment, maintaining the cleanliness of the production environment, and reducing pollution to subsequent production processes.

[0031] The cleaning box 602 contains a rotating shaft 6021, on which a cleaning roller 603 is mounted. Multiple connecting plates 6031 are arranged around the outer surface of the cleaning roller 603, and each connecting plate 6031 has a cleaning brush 6032 connected to its end. A drive motor 604 is bolted to the back of the cleaning box 602, and its output end is connected to the rotating shaft 6021 for transmission. The drive motor 604 drives the rotating shaft 6021 to rotate the cleaning roller 603. The cleaning brush 6032 on the cleaning roller 603 contacts the surface of the conveyor belt to continuously clean the material attached to the conveyor belt. Automatic cleaning is achieved through mechanical rotation, which reduces manual cleaning costs and labor intensity, and improves cleaning efficiency and cleaning effect.

[0032] A collection box 605 is fixedly connected to the bottom of the cleaning box 602. The inner cavities of the cleaning box 602 and the collection box 605 are connected. A protective shell 606 is provided on the front of the collection box 605. A filter screen 607 is provided in the pipe opening connecting the inner cavities of the collection box 605 and the protective shell 606. An opening and closing door is hinged to the back of the collection box 605. The collection box 605 is used to collect materials cleaned from the conveyor belt during the cleaning process for centralized processing. The filter screen 607 can filter the materials entering the protective shell 606 to prevent impurities from entering and protect equipment such as the vacuum motor 6061. The opening and closing door allows staff to open the collection box 605, clean the internal materials, and maintain the normal working condition of the collection box 605.

[0033] The protective housing 606 has a vacuum motor 6061 on its front side, and a fan blade 6062 is connected to the output end of the vacuum motor 6061. Multiple ventilation slots 6063 are provided on both sides of the front of the protective housing 606. When the vacuum motor 6061 drives the fan blade 6062 to rotate at high speed, a negative pressure suction is generated inside the protective housing 606. The multiple ventilation slots 6063 on both sides of the front of the protective housing 606 serve as channels connecting to the outside space, allowing outside air to continuously flow in and form a circulation path with the airflow inside the cleaning box 602. During the airflow circulation process, dust and fine materials inside the cleaning box 602 are entrained by the negative pressure suction and collected. The pipe opening connecting the box 605 and the inner cavity of the protective housing 606 allows the filter screen 607 to trap dust and fine materials within the collection box 605. The flowing air passing through the filter screen 607 is then discharged back to the outside through the ventilation slot 6063. In this way, the vacuum motor 6061 and the fan blade 6062 can continuously generate stable suction force to maintain the vacuuming effect in the cleaning box 602, while also preventing dust and materials from accumulating in the cleaning box 602 and interfering with the cleaning operation. At the same time, it also prevents dust generated during the cleaning process from escaping into the production environment, achieving the dual effect of cleaning environment purification and stable equipment operation.

[0034] The working process of this utility model is as follows: When using a material conveying energy-saving device on a functional fertilizer energy-saving production line, the functional fertilizer first enters the conveyor 2 inside the conveyor frame 1 and begins to move along the production line under the action of the conveyor 2. At the same time, the shielding frame 3 and the shielding plate 301 at the top of the conveyor frame 1 form a closed space, reducing the loss of fertilizer heat to the outside world and creating conditions for heat recovery.

[0035] The exhaust assembly 4 located on the top side of the shielding frame 3 starts to work. The exhaust fan 401 draws in the mixture of heat energy generated by fertilizer volatilization inside the shielding frame 3 and air through the connecting pipe 402 using negative pressure. The mixture is then transported to the external fertilizer production equipment through the conveying pipe 403. During this process, the heat energy generated by fertilizer volatilization is recovered and used in processes such as preheating raw materials, realizing the secondary utilization of energy and effectively reducing the energy consumption of the production line.

[0036] During material conveying, multiple cooling fans 5 on the other side of the top of the shielding frame 3 flexibly adjust their speed and operating status according to the temperature of the functional fertilizer and the ambient temperature. When the fertilizer temperature is too high, the cooling fans 5 accelerate to introduce cold air from outside into the shielding frame 3 to dissipate heat and cool the fertilizer; if the temperature is suitable or low, the speed is reduced or the operation is stopped. In this way, the fertilizer is conveyed at a suitable temperature, avoiding changes in fertilizer composition due to excessive temperature, which would affect product quality, while also ensuring the stability of the conveying process.

[0037] As materials are conveyed, material may adhere to the conveyor belt on the surface of conveyor 2. At this time, the cleaning component 6 comes into play. The through slot 601 at the bottom of the conveyor frame 1 provides a channel for cleaning operations, allowing the cleaning components in the cleaning box 602 to contact the conveyor belt. The drive motor 604 in the cleaning box 602 starts, driving the rotating shaft 6021 to rotate. The rotating shaft 6021 then drives the cleaning roller 603 to rotate. The cleaning brush 6032 on the cleaning roller 603 continuously contacts the surface of the conveyor belt, sweeping off the material adhering to the conveyor belt. The swept-off material falls to the bottom of the cleaning box 602 and enters the collection box 605 through the channel connected to the collection box 605 for centralized storage, preventing material from spilling during the conveying process and affecting the cleanliness of the production environment. At the same time, it reduces the running resistance increased by the accumulation of material on the surface of the conveyor belt, ensuring conveying efficiency.

[0038] The protective shell 606, filter screen 607, vacuum motor 6061, and ventilation slot 6063 on the front of the collection box 605 work together. The vacuum motor 6061 drives the fan blades 6062 to rotate at high speed, creating negative pressure suction inside the protective shell 606. Outside air continuously flows in through the ventilation slots 6063 on both sides of the front of the protective shell 606, forming a circulation path with the airflow inside the cleaning box 602. Dust and fine materials in the cleaning box 602 are carried away by the negative pressure suction and are intercepted by the filter screen 607 inside the collection box 605 when passing through the pipe connecting the inner cavity of the collection box 605 and the protective shell 606. The flowing gas passing through the filter screen 607 is then discharged back to the outside through the ventilation slot 6063. During this process, not only can the vacuum motor 6061 and the fan blade 6062 continuously generate stable suction force to maintain the vacuuming effect in the cleaning box 602, but it also prevents dust and materials from accumulating in the cleaning box 602 and interfering with the cleaning operation, and prevents the dust generated during the cleaning process from escaping into the production environment. This achieves the dual effect of cleaning environment purification and stable equipment operation. When the material collected in the collection box 605 reaches a certain amount, the staff can clean the material inside by opening the door on the back of the collection box 605.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
