[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] At present, when the fertilizer feeding system processes powdered fertilizer raw materials such as phosphate, potash fertilizer, urea, etc., a large number of fine dust particles suspended in the air will be generated due to the collision and friction during the transfer, falling and transportation of the raw materials, causing the workshop environment to be full of dust. Although there are also feeding systems that use dust removal equipment as a dust prevention measure in the feeding workshop, there is still a problem of poor dust removal effect.

[0037] The environmentally friendly fertilizer feeding device provided in the present application sucks the connection position between the material weighing mechanism 100 and the scraper conveyor 200 through the first air duct 302, and uses the negative pressure effect to suppress the dust overflow during the transfer of the material to the scraper conveyor 200, and cooperates with the scraper conveyor 200 for closed transportation, thereby controlling the dust overflow during the transportation process and helping to improve the dust removal effect.

[0038] Please refer to Figure 1 This embodiment provides an environmentally friendly fertilizer feeding system, including a material weighing mechanism 100, a scraper conveyor 200 and a dust removal mechanism 300. The material weighing mechanism 100 is used to weigh the material, the scraper conveyor 200 is used to transport the material weighed by the material weighing mechanism 100, and the dust removal mechanism 300 is used to remove dust generated during the feeding process.

[0039] In one embodiment, referring to Figure 1-Figure 3 The material weighing mechanism 100 includes a feeding platform 101, a feeding hopper 102 and a material weighing device 103. The feeding platform 101 is provided with a feeding port 1011 for feeding materials. The feeding hopper 102 is installed on the feeding platform 101 corresponding to the feeding port 1011. The material weighing device 103 is used to weigh the material transferred out from the feeding hopper 102 and output it to the scraper conveyor 200.

[0040] For example, the environmentally friendly fertilizer feeding system is installed in the feeding workshop as an example. Figure 1-Figure 3The interlayer board in the workshop is used as a feeding table 101. Four feeding ports 1011 are arranged on the feeding table 101. According to production needs, three of the feeding ports 1011 can be used as feeding ports 1011 for feeding large elements (for feeding N, P, and K raw materials), and one feeding port 1011 can be used as a feeding port 1011 for feeding trace elements (for feeding trace element raw materials). The feeding hopper 102 is provided with three feeding ports 1011 corresponding to the macro-elements, and each feeding hopper 102 is located below the illustrated position of a feeding port 1011 of the macro-elements, and the material weigher 103 matched with the feeding hopper 102 is a belt weigher; and the feeding hopper 102 and the material weigher 103 matched with the feeding port 1011 of the trace elements adopt a screw feeder 104, that is, the hopper of the screw feeder 104 is used as the feeding hopper 102, and the quantitative feeding mechanism of the screw feeder 104 is used as the material weigher 103. This helps to reduce dust emission during the transfer process from the feeding hopper 102 to the material weigher 103.

[0041] In other examples, the feeding platform 101 may also be an independently set high platform with a feeding platform 101 surface, and there is enough space below the feeding platform 101 surface to install the feeding hopper 102 and the material weighing device 103. The number and purpose of the feeding ports 1011 can also be adjusted as needed. As for the setting of the feeding hopper 102 and the material weighing device 103, the above-mentioned feeding hopper 102 and belt weighing device or the screw feeder 104 can be flexibly selected as needed. Of course, other feeding and weighing methods that can meet the design and use requirements, such as hopper weighing devices, can also be selected.

[0042] Furthermore, the feed port of the hopper 102 can be arranged close to or sealed with the feed port 1011 to reduce dust emission during the transfer of raw materials from the feed port 1011 to the hopper 102 .

[0043] In one embodiment, referring to Figure 2 , a feeding net 1012 is installed on the feeding port 1011, and the raw materials can be preliminarily filtered through the feeding net 1012. Exemplarily, the feeding net 1012 adopts a steel structure feeding net 1012 that can bear a load. For example, a steel structure feeding net 1012 that can bear a load of 6 tons is installed to meet the needs of forklift travel, so that the movement of the forklift is not restricted by the feeding port 1011. In other embodiments, the feeding net 1012 can also be made of other materials such as engineering plastics or aluminum alloys, and its load bearing range can also be designed as needed, such as only enough to bear the load bearing capacity of the operator's operation and passing. Of course, a feeding net 1012 that only performs filtering and does not need to bear other loads can also be used.

[0044] In one embodiment, referring to Figure 2 and Figure 3 , a transport feed port 201 is provided on the casing of the scraper conveyor 200, and the discharge end of the material weigher 103 extends into the transport feed port 201. Exemplarily, the transport feed port 201 is provided on the casing of the scraper conveyor 200 corresponding to the discharge end position of each material weigher 103, and the transport feed port 201 is a hopper-type structure, and the discharge end of the scraper conveyor 200 extends into the transport feed port 201 from an opening provided on the side wall of one side of the transport feed port 201. The provision of the transport feed port 201 helps to suppress the overflow of dust generated during the transfer of materials from the material weigher 103 to the scraper conveyor 200. Furthermore, the feeding smoothness can be improved by increasing the size of the connection between the transport feed port 201 and the shell of the scraper conveyor 200, such as changing the size of the connection from 20cm*20cm to 20cm*40cm.

[0045] In one embodiment, the scraper conveyor 200 can also be composed of multiple stages of scraper conveyors 200, such as: a scraper conveyor 200 is set corresponding to each material weigher 103, the discharge end of the material weigher 103 extends into the transport feed port 201 set on the corresponding scraper conveyor 200, and the scraper conveyors 200 of each stage are connected end to end. In short, the scraper conveyor 200 can be set in one or more stages as long as it can meet the transportation needs.

[0046] In one embodiment, referring to Figure 1 The dust removal mechanism 300 includes a dust removal fan 301 and a first air duct 302, and the first air duct 302 is connected between the transport feed port 201 and the dust extraction pipe of the dust removal fan 301. Exemplarily, the dust removal fan 301 adopts a bag-type dust removal fan 301, which is specifically arranged on the feeding platform 101. The dust extraction pipe of the dust removal fan 301 passes through the feeding platform 101 and extends to the area where the material weighing mechanism 100 is located. A connector 3021 is provided on the dust extraction pipe of the dust removal fan 301 corresponding to each transport feed port 201, and a connector 3021 is also provided on each transport feed port 201. The first air duct 302 is connected between the corresponding two connectors 3021, so that the inner cavity of each transport feed port 201 and the air extraction pipe of the dust removal fan 301 are connected. When the dust removal fan 301 is working, negative pressure can be formed at the transport feed port 201 to collect dust generated during the transfer from the material weigher 103 to the scraper conveyor 200, thereby reducing dust overflow.

[0047] Furthermore, the first air duct 302 is a flexible tube, so that the dust extraction pipe of the dust removal fan 301 and the transport feed port 201 form a soft connection mode, that is, the first air duct 302 is softly connected between the transport feed port 201 and the dust extraction pipe of the dust removal fan 301 to prevent the vibration of the dust extraction pipe from being transmitted to the transport feed port 201 when the dust removal fan 301 is working, which helps to reduce noise and maintain the effectiveness of the connection. In other embodiments, the connector 3021 can also be set as a flexible connector 3021 to achieve soft connection or adopt other feasible soft connection methods.

[0048] In one embodiment, referring to Figure 1 The dust outlet of the dust removal fan 301 is connected to a guide pipe 303, and the guide pipe 303 is connected to the transport cavity of the scraper conveyor 200 to send the dust collected by the dust removal fan 301 to the transport cavity of the scraper conveyor 200. The dust collected by the dust removal fan 301 is immediately transported and digested by the scraper conveyor 200, so that the dust can be immediately digested and used, and the dust-free material can be produced. In addition, the dust material can be returned to the feeding system in time for subsequent production, which helps to reduce the fluctuation of the fertilizer content.

[0049] In one embodiment, referring to Figure 1 The dust extraction pipe of the dust removal fan 301 is provided with cleaning ports 304 spaced apart along the axis direction of the dust extraction pipe, and the cleaning ports 304 are movably provided with sealing doors 3041. For example, a waste belt can be hung on the cleaning port 304 as the sealing door 3041, which is convenient for daily cleaning and sealing of accumulated materials in the dust extraction pipe.

[0050] In one embodiment, referring to Figure 1 The environmentally friendly fertilizer feeding system also includes a bucket elevator 400 and a mixer 500. The feed port of the bucket elevator 400 is connected to the discharge port of the scraper conveyor 200, and the feed port of the mixer 500 is connected to the discharge port of the bucket elevator 400. The raw materials delivered by the scraper conveyor 200 can be lifted by the bucket elevator 400 and sent to the mixer 500 for mixing, and then enter the subsequent process equipment for processing.

[0051] In a further embodiment, referring to Figure 4 A material receiving baffle 401 is extended from one end of the bucket elevator 400 unloading chute in the bucket elevator 400 lifting chamber, and the material receiving baffle 401 is used to reduce the gap between the bucket elevator 400 unloading chute and the bucket bowl, so as to improve the problem that the gap between the bucket bowl of the bucket elevator 400 and the unloading chute is too large, and the material in the bucket bowl of the bucket elevator 400 cannot be normally thrown to the unloading chute, which leads to the wind pressure generated by the reflux of the material from the top of the bucket elevator 400 blowing the material at the feeding port of the bucket elevator 400 out.

[0052] In one embodiment, referring to Figure 1The dust removal mechanism 300 further includes a second air duct 305, one end of which is connected to the dust extraction pipe of the dust removal fan 301, and the other end is connected to the transport chamber of the scraper conveyor 200. In this way, when the dust removal fan 301 is working, it can form a certain intensity of negative pressure in the scraper conveyor 200 through the second air duct 305 to collect the dust blown out from the feed port of the bucket elevator 400 by the wind pressure generated by the reflux of the material in the bucket elevator 400. Exemplarily, the connection between the second air duct 305 and the scraper conveyor 200 is set at one end of the scraper conveyor 200 and the bucket elevator 400.

[0053] In an embodiment of a fertilizer production system, the fertilizer production system includes the environmentally friendly fertilizer feeding device of any of the above embodiments.

[0054] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention.
