Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer processing technology, and more specifically, to a compound fertilizer cooling and washing device. Background Technology

[0002] Compound fertilizers are fertilizers composed of two or more nutrients working synergistically. They are typically used to improve soil fertility and crop yield. The production process of compound fertilizers involves various chemical reactions and physical processes, including drying and granulation. The drying process usually involves heating with high-temperature air or hot air. Due to the high temperature of the heat source, a large amount of hot air is generated during the drying process, forming high-temperature waste gas. In the granulation process, heating is usually required to melt or bind the surface of the fertilizer particles. This process also involves the generation of high-temperature gases, especially when using melt granulation technology. The high-temperature waste gas generated at this stage not only contains water vapor but may also contain some volatile organic compounds and other gases. The treatment of these gases is also an important part of environmental protection. The compound fertilizer cooling and washing device is one of the important pieces of equipment in fertilizer production. It is mainly used to cool, wash, and purify the high-temperature waste gas generated during the compound fertilizer production process. Since there are multiple inspection doors on the front of the cooling and washing device, it is necessary to protect these inspection doors during operation.

[0003] In related technologies, during the use of cooling washing devices, the inspection door is typically opened and closed using bolts, allowing staff to perform regular inspections, maintenance, and repairs on the inside of the cooling washing device before it is put into use.

[0004] However, during the current use of the cooling washing device, since the inspection door is located on the outside of the device and is connected and opened by bolts, it is prone to corrosion and rust after being affected by rainwater and dirt. This can damage the inspection area of ​​the cooling washing device and affect its maintenance and protection. Utility Model Content

By holding the protective frame 4, the protective seat 5 is moved to the top of the maintenance door 2, and the maintenance door 2 is positioned inside the protective strip 6. The protective strip 6 is moved inward to contact the surface of the maintenance door 2. Then, by holding the protective frame 4, the protective seat 5 and the protective strip 6 are moved forward, so that the protective pads 7 contact the maintenance door 2. The protective strip 6 and the inspection door 2 are in contact with each other to prevent slippage, so that the protective frame 4 can stably cover and protect the inspection door 2. The protective force application mechanism includes a force application seat 8, a force application frame 9 and a force application plate 10. The force application seat 8 is fixedly connected to the front side of the top of the inner wall of the protective frame 4, the force application frame 9 is movably connected to the bottom of the force application seat 8, and the force application plate 10 is fixedly connected to the rear side of the force application frame 9. The protective strip 6 can provide the user with a medium to apply a protective stabilizing force between the protective frame 4 and the inspection door 2, so that the user can perform a stabilizing operation between the protective frame 4 and the inspection door 2, avoiding the situation where it is difficult to apply a stabilizing force when using the protective frame 4. Therefore, the force stabilizing protection effect and convenience of the protective frame 4 are improved.

[0032] Reference Figures 2-4In a preferred embodiment, a sliding groove 11 is provided at the bottom of the force-applying seat 8, and a slide block 12 is movably connected inside the sliding groove 11. The bottom of the slide block 12 is fixedly connected to the top of the force-applying frame 9, which allows for a sliding connection between the force-applying frame 9 and the force-applying seat 8 to apply force, thus preventing the force-applying frame 9 from separating from the force-applying seat 8 during use.

[0033] Reference Figures 2-4 In a preferred embodiment, a rotating hole 15 is provided on the rear side of the force-applying seat 8, and a rotating frame 16 is movably connected inside the rotating hole 15. The front side of the rotating frame 16 is fixedly connected to the rear side of the screw 14, which can provide rotational support between the screw 14 and the force-applying seat 8, thus improving the connection effect between the screw 14 and the force-applying seat 8.

[0034] Reference Figures 2-3 In a preferred embodiment, a translation groove 19 is provided at the bottom of the protective base 5, and translation seats 20 are movably connected to both sides of the translation groove 19. The bottom of the translation seats 20 is fixedly connected to the top of the protective strip 6, which allows for translational connection between the protective strip 6 and the protective base 5. This improves the connection effect between the protective strip 6 and the protective base 5. A screw cavity 21 is provided inside the translation seat 20, and a double-ended stud 22 is threaded inside the screw cavity 21. The outer side of the double-ended stud 22 extends to the outer side of the protective frame 4. The translation seat 20 provides a medium for the synchronous movement of the two protective strips 6, avoiding the situation where the protective strips 6 are difficult to move during use. This improves the convenience and synchronicity of the movement of the protective strips 6.

[0035] Specifically, the working process or working principle of this compound fertilizer cooling and washing device is as follows: During use, the protective frame 4 is held and the protective seat 5 is placed on top of the inspection door 2, with the inspection door 2 positioned inside the protective strip 6, and the front of the inspection door 2 positioned behind the force-applying plate 10, preparing for the subsequent application of a clamping and stabilizing force by the force-applying plate 10. Then, the double-ended stud 22 is rotated to engage with the screw cavity 21, applying a synchronously moving threaded thrust to the translation seat 20, causing the translation seat 20 to move the protective strip 6 inwards, contacting the surface of the inspection door 2. At this time, the protective strip 6, in conjunction with the protective seat 5, performs a protective clamping pre-stabilization operation between the protective frame 4 and the inspection door 2. Simultaneously, the translation seat 20 moves inside the translation groove 19, performing translational connection and guiding work between the protective strip 6 and the protective seat 5. Finally, the protective frame 4 is held and the protective seat 5 and protective strip 6 are moved forwards... The protective pad 7 is moved to contact the inspection door 2. Then, the screw 14 is rotated to apply threaded thrust to the slide 12 through the screw hole 13, causing the slide 12 to move backward through the force-applying frame 9 to contact and abut against the front of the inspection door 2. At this time, the protective seat 5, together with the protective strip 6, assists the force-applying plate 10 to perform force clamping and stabilizing work between the protective frame 4 and the inspection door 2, stabilizing the protective frame 4 on the top of the inspection door 2. At this time, the rotating frame 16 follows the screw 14 and rotates inside the rotating hole 15, performing rotational support connection work between the screw 14 and the force-applying seat 8. At the same time, the rotating frame 16, together with the magnetic ring 17 and the magnetic suction ring 18, performs magnetic suction positioning work between the screw 14 and the force-applying seat 8 after the operation, ensuring the stability of the screw 14 after the operation, stabilizing the protective frame 4 on the top of the inspection door 2, and covering and protecting the inspection door 2.

[0036] It should be noted that the cooling washing tower 1, the inspection door 2 and the air inlet head 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
