Description

Technical Field

[0001] This utility model relates to the field of impurity removal and pretreatment technology, and in particular to a compound fertilizer raw material impurity removal and pretreatment device. Background Technology

[0002] Compound fertilizer raw materials refer to the basic materials used in the production of compound fertilizers. They are usually composed of a mixture of various mineral fertilizers, micronutrient fertilizers, and other auxiliary materials. These raw materials are often accompanied by some impurities in nature, such as soil, stones, sand, and plant residues. These impurities not only affect the quality and effectiveness of the fertilizer, but may also damage the production equipment or increase the difficulty of subsequent processing. Therefore, it is necessary to remove these impurities through a compound fertilizer raw material impurity removal pretreatment device to ensure that the quality of the final product is more stable and uniform, while improving the safety of production and the durability of the equipment.

[0003] Currently, there are various types of compound fertilizer raw material impurity removal pretreatment devices on the market. However, these devices are not convenient for efficiently separating particles of different sizes when screening raw materials. The screening effect is not precise enough, which affects the subsequent screening and treatment of impurities of different sizes, increases the difficulty of subsequent processing, and makes it difficult to further improve the overall work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pretreatment device for removing impurities from compound fertilizer raw materials.

[0005] This utility model is achieved by the following technical solution: a compound fertilizer raw material impurity removal pretreatment device, including a transmission mechanism, a cleaning mechanism and a protective mechanism, wherein the transmission mechanism is located inside the protective mechanism and the cleaning mechanism is located outside the transmission mechanism;

[0006] The transmission mechanism includes a drive motor, the output end of which is fixedly connected to an auger. A fixed pipe is installed on the surface of the auger, and a connecting pipe is fixedly connected to the top of the fixed pipe. A filter barrel is fixedly connected to one side of the fixed pipe. A filter screen one is fixedly connected to the bottom of the filter barrel, and a filter screen two is fixedly connected to the bottom of the filter barrel. A groove is provided at the bottom of the filter barrel, and a partition plate is fixedly connected to the bottom of the filter barrel. A collection box one is installed below the filter screen one, a collection box two is installed below the filter screen two, and a collection box three is installed below the groove.

[0007] Through the above technical solution, the separator plate can effectively separate the filter barrel, so that raw materials of different sizes fall into the matching collection box one and collection box two, and collection box three is used to collect large impurities.

[0008] As a further improvement to the above solution, the number of fixed tubes is set to two, and the two fixed tubes are symmetrically distributed front and back with the partition plate as the center, and the filter bucket is located on the left side of the fixed tubes.

[0009] Through the above technical solution, the symmetrically arranged fixed pipes can transport materials separately. When the auger inside one of the fixed pipes is damaged, the auger inside the other fixed pipe can still continue to operate.

[0010] As a further improvement to the above solution, the auger is located inside the filter barrel, and the second filter screen is located between the first filter screen and the groove.

[0011] As a further improvement to the above solution, the cleaning mechanism includes a water tank, a water outlet pipe fixedly connected to the rear end of the water tank, a branch pipe fixedly connected to the top of the water outlet pipe, a spray nozzle fixedly connected to the front end of the branch pipe, and an auxiliary plate fixedly connected to the bottom of the partition plate.

[0012] Through the above technical solution, the nozzle can spray water from inside the water tank to remove impurities attached to the surface of the raw materials, and the auxiliary plate is used to provide stable support.

[0013] As a further improvement to the above solution, the first collection box, the second collection box, and the third collection box are all slidably connected to the upper end of the auxiliary plate, and the water tank is located on the right side of the partition plate.

[0014] As a further improvement to the above solution, the protective mechanism includes a housing, a water inlet pipe fixedly connected to the front end of the housing, a discharge pipe fixedly connected to one side of the housing, a feed box fixedly connected to the upper end of the housing, a baffle slidably connected to the inner wall of the feed box, and a support frame fixedly connected to the inner wall of the housing.

[0015] Through the above technical solution, the support frame can provide stable support for the fixed pipe, thereby ensuring the stable operation of the device as a whole. At the same time, the support frame can also effectively protect the water tank. When there is no water in the water tank, new water can be added into the water tank through the water inlet pipe.

[0016] As a further improvement to the above solution, the surface of the connecting pipe is fixedly connected to the inner wall of the baffle, and the water tank is located inside the support frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a transmission mechanism to transport raw materials from the feed hopper into the filter barrel. A drive motor rotates the auger, and after the raw materials enter the filter barrel, fine particles fall through filter screen one into collection box one, while larger particles continue to be transported by the auger to filter screen two. After screening, large impurities remaining inside the filter barrel are sent to the groove by the auger and fall into collection box three. The entire device can screen raw materials of different sizes and promptly remove large impurities, thereby reducing interference with subsequent processing. Operators can easily remove the screened raw materials and impurities by pulling collection boxes one, two, and three, further improving work efficiency.

[0019] This invention transports water from the tank to various branch pipes via the outlet pipe, and finally sprays it out from the nozzle to clean the raw materials in each collection box. When one of the augers is damaged, the operator can isolate the damaged part through the baffle and continue to use the undamaged auger, avoiding downtime and production interruption, and further improving the working efficiency and continuity of the device.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 The compound fertilizer raw material impurity removal pretreatment device of this embodiment includes a transmission mechanism 1, a cleaning mechanism 2 and a protective mechanism 3. The transmission mechanism 1 is located inside the protective mechanism 3, and the cleaning mechanism 2 is located outside the transmission mechanism 1.

[0030] The transmission mechanism 1 includes a drive motor 11, the output end of which is fixedly connected to an auger 15. A fixed pipe 12 is mounted on the surface of the auger 15, and a connecting pipe 13 is fixedly connected to the top of the fixed pipe 12. A filter barrel 14 is fixedly connected to one side of the fixed pipe 12. A filter screen 16 and a filter screen 17 are fixedly connected to the bottom of the filter barrel 14. A groove 18 is provided at the bottom of the filter barrel 14, and a partition plate 19 is fixedly connected to the bottom of the filter barrel 14. A collection box 191 is installed below the filter screen 16, a collection box 192 is installed below the filter screen 17, and a collection box 193 is installed below the groove 18. The partition plate 19 can effectively separate the filter barrel 14, allowing raw materials of different sizes to fall into the matching collection boxes 191 and 192. The collection box 193 is used to collect large impurities.

[0031] The number of fixed pipes 12 is set to two, and the two fixed pipes 12 are symmetrically distributed front and back with the partition plate 19 as the center. The filter barrel 14 is located on the left side of the fixed pipe 12. The symmetrically arranged fixed pipes 12 can separate and transport materials. When the auger 15 inside one of the fixed pipes 12 is damaged, the auger 15 inside the other fixed pipe 12 can still continue to operate.

[0032] The screw conveyor 15 is located inside the filter barrel 14, and the second filter screen 17 is located between the first filter screen 16 and the groove 18.

[0033] The cleaning mechanism 2 includes a water tank 21, a water outlet pipe 22 fixedly connected to the rear end of the water tank 21, a branch pipe 23 fixedly connected to the top of the water outlet pipe 22, a nozzle 24 fixedly connected to the front end of the branch pipe 23, and an auxiliary plate 25 fixedly connected to the bottom of the partition plate 19. The nozzle 24 can spray water from inside the water tank 21 to remove impurities attached to the surface of the raw materials. The auxiliary plate 25 is used to provide stable support.

[0034] Collection boxes 191, 192 and 193 are all slidably connected to the upper end of the auxiliary plate 25, and the water tank 21 is located on the right side of the partition plate 19.

[0035] The protective mechanism 3 includes a housing 31. A water inlet pipe 32 is fixedly connected to the front end of the housing 31. A discharge pipe 33 is fixedly connected to one side of the housing 31. A feed box 34 is fixedly connected to the upper end of the housing 31. A baffle 35 is slidably connected to the inner wall of the feed box 34. A support frame 36 is fixedly connected to the inner wall of the housing 31. The support frame 36 can provide stable support for the fixed pipe 12, thereby ensuring the stable operation of the entire device. At the same time, the support frame 36 can also effectively protect the water tank 21. When there is no water inside the water tank 21, new water can be added to the inside of the water tank 21 through the water inlet pipe 32.

[0036] The surface of the connecting pipe 13 is fixedly connected to the inner wall of the baffle 35, and the water tank 21 is located inside the support frame 36.

[0037] The implementation principle of the compound fertilizer raw material impurity removal pretreatment device in this application embodiment is as follows: The operator starts the drive motor 11 by connecting an external power source. The drive motor 11 drives the auger 15 to rotate, pouring the raw material into the feed box 34. The raw material then enters each fixed pipe 12 through two connecting pipes 13, allowing the auger 15 to transport the raw material, preparing it for subsequent screening. After the auger 15 transports the raw material into the filter barrel 14, the finer particles inside can pass through the filter screen... 16 falls into the collection box 191. At this time, larger materials remain in the filter barrel 14. The auger 15 can then transport the remaining materials to the top of the filter screen 17. The larger materials will then fall through the filter screen 17 into the collection box 192. Finally, only large impurities remain in the filter barrel 14. The auger 15 can then transport them to the groove 18, allowing them to fall into the collection box 193, thus completing the screening of the materials. After screening, the operator can drain the material through water. The pump transports water from the water tank 21 to the outlet pipe 22, and then to each branch pipe 23. Finally, the water is sprayed out from the nozzle 24. The sprayed water washes the raw materials inside each collection box, removing impurities. The washed water is collected from the bottom of each collection box through the auxiliary plate 25 into the wastewater tank inside the shell 31, and finally discharged through the discharge pipe 33. The operator can pull the handle to pull out collection box 1 191, collection box 2 192, and collection box 3 193, thereby discharging the screened raw materials. Material is removed, and the partition plate 19 provides stable support for the filter barrel 14, while the support frame 36 provides stable support for the fixed pipe 12, thereby ensuring that the auger 15 can operate stably. When one of the augers 15 is damaged, the operator puts the feed box 34 into the inside of the baffle 35 to separate it, and pours the raw material into the undamaged auger 15 for operation. The entire device can effectively screen the raw material, and at the same time, it can facilitate the operator to collect the screened and cleaned raw material, further improving work efficiency.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
