Description

Technical Field

[0001] This utility model relates to the field of solid compound fertilizer production technology, specifically to a drying equipment for solid compound fertilizer production. Background Technology

[0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrients. Compound fertilizer has the advantages of high nutrient content, few by-products and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable crop yields. In the process of drying compound fertilizer, the traditional drying method is to place the compound fertilizer in a box for drying. After drying one batch of compound fertilizer, it is necessary to take out the dried compound fertilizer before the next batch of fertilizer can be dried. The operation is relatively cumbersome and the drying efficiency is low. Utility Model Content

[0003] The purpose of this invention is to provide a drying device for the production of solid compound fertilizers, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drying device for solid compound fertilizer production, comprising a drying device shell, wherein a feed inlet is provided at the top of the drying device shell, and a material outlet is provided on the front and back of the drying device shell, the material outlet being close to the bottom of the drying device shell, and a drying mechanism is provided inside the drying device shell;

[0005] The drying mechanism includes three inclined guide plates arranged in a stepped manner inside the drying equipment shell. Slide rods are fixedly installed at the bottom of the left and right ends of each inclined guide plate. Guide plates are slidably fitted onto the outer walls of the slide rods. The guide plates are fixedly installed on the inner wall of the drying equipment shell. A spring elastically connects the guide plates to the bottom of the inclined guide plates. A vibrator is fixedly installed at the bottom of the inclined guide plates. A discharge port is opened at the bottom of the inclined guide plates, located near the bottommost end. Multiple direct heating devices are fixedly installed at the bottom of the inclined guide plates, distributed at different positions on the inclined guide plates. The ends of the direct heating devices extend above the inclined guide plates. A hot air drying component is installed at the top of the inclined guide plates.

[0006] Furthermore, the direct heating device includes a heat-conducting shell, and a heat-insulating layer plate is fixedly installed on the inner wall of the heat-conducting shell. The heat-insulating layer plate divides the heat-conducting shell into a hot oil chamber and a drying chamber. An electric heater is provided in the drying chamber. A heating wire is heat-conductingly installed at the heating end of the electric heater. The heating wire extends into the hot oil chamber, which is filled with heat-conducting oil.

[0007] Furthermore, the hot air drying component includes a U-shaped outer shell, which is fixedly installed on the top of the inclined guide plate. An air blowing head is fixedly installed on one outer wall of the U-shaped outer shell, and an air suction head is fixedly installed on the other outer wall. The openings of the air blowing head and the air suction head are both located inside the U-shaped outer shell.

[0008] Furthermore, the feed inlet and drying mechanism are each provided in two sets, and are symmetrically distributed about the center of the drying equipment shell.

[0009] Furthermore, a high-temperature resistant rubber pad is fixedly installed at the bottom of the inclined guide plate. The high-temperature resistant rubber pad is located between the discharge port and the bottom of the inclined guide plate, and the bottom of the high-temperature resistant rubber pad is fixedly connected to the top of the guide plate.

[0010] Furthermore, a hot air blower and an air pump are fixedly installed on the top of the drying equipment shell. The air outlet of the hot air blower is connected to the inside of the air blowing head through a hose, and the air inlet of the air pump is connected to the inside of the air suction head through a hose.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Three inclined guide plates distributed in a stepped manner are used to transport and guide the fertilizer, so that the fertilizer passes through the three inclined guide plates from top to bottom in sequence. Then, when passing through the inclined guide plates, it is dried by the hot air drying component and the direct heating device. The fertilizer is constantly flowing throughout the drying process, so fertilizer can be continuously added from the feed inlet to achieve the purpose of continuous drying.

[0013] 2. Because the inclined guide plate and the guide plate are elastically connected by a spring, the vibrator at the bottom of the inclined guide plate can make the inclined guide plate vibrate up and down when it works. On the one hand, it can shake the piled fertilizer apart, making the drying effect better. On the other hand, it can prevent the fertilizer from sliding along the inclined guide plate under its own gravity. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a drying equipment for solid compound fertilizer production, including a drying equipment shell 1, a feeding port 2 opened on the top of the drying equipment shell 1, a feeding port 3 opened on the front and back of the drying equipment shell 1, the feeding port 3 being close to the bottom of the drying equipment shell 1, and a drying mechanism 4 being provided inside the drying equipment shell 1.

[0022] The drying mechanism 4 includes three inclined guide plates 401 arranged in a stepped manner inside the drying equipment shell 1. Slide rods 406 are fixedly installed at the bottom of both ends of the inclined guide plates 401. Guide plates 404 are slidably sleeved on the outer walls of the slide rods 406. The guide plates 404 are fixedly installed on the inner walls of the drying equipment shell 1. A spring 405 elastically connects the guide plates 404 and the bottom of the inclined guide plates 401. A vibrator 408 is fixedly installed at the bottom of the inclined guide plates 401. A discharge port 407 is opened at the bottom of the inclined guide plates 401, located near the bottommost end of the inclined guide plates 401. Multiple direct heating devices 403 are fixedly installed at the bottom of the inclined guide plates 401, distributed at different positions on the inclined guide plates 401. The ends of the direct heating devices 403 extend into the inclined guide plates. Above the guide plate 401, a hot air drying component 402 is provided on the top of the inclined guide plate 401. The fertilizer is conveyed and guided by three inclined guide plates 401 arranged in a stepped manner, so that the fertilizer passes through the three inclined guide plates 401 in sequence from top to bottom. Then, when passing through the inclined guide plates 401, it is dried by the hot air drying component 402 and the direct heating device 403. The fertilizer is constantly flowing throughout the drying process, so fertilizer can be continuously added from the feed inlet 2 to achieve the purpose of continuous drying. Because the inclined guide plate 401 and the guide plate 404 are elastically connected by a spring 405, the vibrator 408 at the bottom of the inclined guide plate 401 can make the inclined guide plate 401 vibrate up and down when it works. On the one hand, it can shake the fertilizer that is piled up together, so as to improve the drying effect. On the other hand, it can prevent the fertilizer from being unable to slide along the inclined guide plate 401 under its own gravity.

[0023] The direct heating device 403 includes a heat-conducting shell 4031. A heat-insulating layer plate 4032 is fixedly installed on the inner wall of the heat-conducting shell 4031. The heat-insulating layer plate 4032 divides the heat-conducting shell 4031 into a hot oil chamber and a drying chamber. An electric heater 4033 is provided in the drying chamber. A heating wire 4034 is heat-conductingly installed at the heating end of the electric heater 4033. The heating wire 4034 extends into the hot oil chamber, which is filled with heat-conducting oil. The electric heater 4033 heats the heating wire 4034, which in turn heats the heat-conducting oil, causing the heat-conducting shell 4031 to heat up. When the fertilizer passes through the heat-conducting shell 4031, it is heated by the heat-conducting shell 4031.

[0024] The hot air drying component 402 includes a U-shaped outer shell 4021, which is fixedly installed on the top of the inclined guide plate 401. An air blowing head 4022 is fixedly installed on one outer wall of the U-shaped outer shell 4021, and an air suction head 4023 is fixedly installed on the other outer wall. The openings of the air blowing head 4022 and the air suction head 4023 are both located inside the U-shaped outer shell 4021. The U-shaped outer shell 4021 is set up for protection to prevent fertilizer from falling from the edge of the inclined guide plate 401. At the same time, it can also limit the range of hot air blown out by the air blowing head 4022 to ensure that the hot air blows towards the fertilizer. The air suction head 4023 is set up to recover the hot air involved in drying the fertilizer. This part of the hot air contains a lot of moisture. If it stays inside the U-shaped outer shell 4021 for a long time, it will also affect the subsequent drying of fertilizer.

[0025] The feed inlet 2 and the drying mechanism 4 are both provided with two sets, and are symmetrically distributed about the center of the outer shell 1 of the drying equipment, which increases the drying structure and thus improves the drying efficiency.

[0026] A high-temperature resistant rubber pad 5 is fixedly installed at the bottom of the inclined guide plate 401. The high-temperature resistant rubber pad 5 is located between the discharge port 407 and the bottom of the inclined guide plate 401. The bottom of the high-temperature resistant rubber pad 5 is fixedly connected to the top of the guide plate 404. The high-temperature resistant rubber pad 5 is set to prevent fertilizer from falling from the discharge port 407 and then falling onto the guide plate 404, thus preventing it from participating in the subsequent drying or material handling steps.

[0027] A hot air blower 6 and an air pump 7 are fixedly installed on the top of the outer shell 1 of the drying equipment. The air outlet of the hot air blower 6 is connected to the inside of the air blowing head 4022 through a hose, and the air inlet of the air pump 7 is connected to the inside of the air suction head 4023 through a hose. Hot air is generated by the hot air blower 6 and enters the air blowing head 4022 through the hose. The air pump 7 draws the air out of the air suction head 4023, so that the hot air participating in the drying is drawn into the air suction head 4023.

[0028] Working principle: During use, the vibrator 408, electric heater 4033, hot air blower 6, and air pump 7 are turned on. The vibrator 408 causes the inclined guide plate 401 to vibrate up and down. Then, fertilizer is added into the drying equipment shell 1 through the feed port 2. The fertilizer falls onto the inclined guide plate 401 and slides along the vibrating inclined guide plate 401 until it reaches the discharge port 407. Then, it falls into the inclined guide plate 401 below from the discharge port 407. While the fertilizer slides on the inclined guide plate 401, the direct heating device 403 heats the fertilizer, while the air blower 4022 blows hot air onto the fertilizer. The hot air, together with the direct heating device 403, dries the fertilizer, ensuring the drying effect. After the fertilizer slides through the three inclined guide plates 401 in sequence, it falls onto the bottom inner wall of the drying equipment shell 1 and is taken out through the discharge port 3. During the drying process, fertilizer can be continuously added from the feed port 2 to achieve the purpose of continuous drying.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
