Description

Technical Field

[0001] This utility model belongs to the field of urea production technology, specifically a urea production filter-type feeding tank that facilitates quick replacement of the filter element. Background Technology

[0002] Urea, also known as urea or carbamide, has the chemical formula CH4N2O or CO(NH2)2. It is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. It is a white crystalline solid. Urea production is a typical continuous chemical process. From raw materials (ammonia, carbon dioxide) to finished products (granular urea, molten urea), it needs to go through multiple processes such as synthesis, separation, evaporation, and granulation. The feeding tank is a "key link in raw material pretreatment" (responsible for filtering mechanical impurities, rust residue, and particulate contaminants in the raw materials). Once the machine is stopped to replace the core, it will directly lead to the interruption of the supply of materials to subsequent processes.

[0003] Meanwhile, a chemical urea production feeding tank with application number CN202321588208.0 includes a buffer silo and a feeding trough. The feeding trough is located below the buffer silo, and a feeding pipe connects the bottom of the buffer silo and the feeding trough. A stirring rod is installed inside the buffer silo, and a first spiral blade is installed on the stirring rod, which cooperates with the inner cavity of the buffer silo. Several stirring blades are fixed on the lower surface of the stirring rod, which cooperate with the first spiral blade. A rotating rod is fixed at the lower end of the stirring rod, and the rotating rod is located inside the feeding pipe. A second spiral blade is installed on the rotating rod, and the second spiral blade cooperates with the inner cavity of the feeding pipe. A rotating shaft is rotatably installed inside the feeding trough, and a third spiral blade is installed on the rotating shaft, which cooperates with the inner cavity of the feeding trough. A funnel-shaped feeding port is fixed at the upper end of the buffer silo, and the lower part of the interior of the buffer silo has a funnel-shaped structure.

[0004] However, the following problems were found in the implementation of the relevant technologies: the traditional feeding tanks still widely used in urea production have obvious defects in their filter replacement design. When replacing the filter, 4-8 fixing bolts need to be removed with a wrench, and then the old filter needs to be taken out and the new filter needs to be installed. Precise alignment is required, and then the bolts need to be tightened again. The filter replacement efficiency is extremely low, and the downtime losses are huge. It has become a key bottleneck restricting production efficiency, product quality and operational safety.

[0005] Therefore, we propose a urea production filter-type feeding tank that facilitates quick filter element replacement. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a urea production filter-type feeding tank that facilitates quick filter element replacement. It has the advantages of allowing for quick installation and removal of the filter element, ensuring the stability of the filter element installation, and allowing for replacement without touching the filter element by hand, thus reducing the risk of infection, skin irritation, or chemical burns.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a urea production filter-type feeding tank for easy and quick filter element replacement, comprising a feeding tank body, a slot provided in the feeding tank body, a rotating groove provided at the lower end of the slot, slots provided on the upper and lower sides of the rotating groove, a locking mechanism fixedly connected in the slots, a filter element detachably connected in the feeding tank body, an insert block fixedly connected to the outer surface of the filter element, slots provided on the upper and lower sides of the insert block, a conical block fixedly connected to the upper surface of the filter element, a positioning block fixedly connected to the outer surface of the conical block; a control rod, a locking block fixedly connected to the lower surface of the control rod, the locking block being provided with a positioning hole, and a magnet fixedly connected to the upper surface of the conical block inside the locking block.

[0008] Preferably, the locking mechanism includes a mounting plate located on the bottom surface of the slot, a spring fixedly connected to the upper surface of the mounting plate, a limit plate fixedly connected to the upper surface of the spring, and a locking block fixedly connected to the upper surface of the limit plate.

[0009] Preferably, the locking block is movably connected to the card slot.

[0010] Preferably, a slider is fixedly connected to the outer surface of the limiting plate, a groove is provided in the slot, and the slider is slidably connected to the groove.

[0011] Preferably, a control handle is fixedly connected to the upper surface of the control lever, and the control handle is provided with anti-slip texture.

[0012] Preferably, the locking block is movably connected to the conical block, and the positioning hole is movably connected to the positioning block.

[0013] Preferably, the insert block is slidably connected to the slot, and the insert block is slidably connected to the rotating groove.

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

[0015] 1. This utility model, through the cooperation of slots, rotating grooves, slotting, locking mechanisms, filter elements, insert blocks and card slots, allows for quick installation and removal of filter elements. The quick locking mechanism and positioning design shorten the filter element replacement process from the traditional time-consuming disassembly and assembly operation to within a few minutes. The replacement process can be completed by a single person. The simplified locking and releasing improves on-site flexibility and ensures the stability of filter element installation.

[0016] 2. This utility model allows for filter replacement without hand contact by using a conical block, positioning block, control rod, locking block, positioning hole, and magnetic block. This avoids direct hand contact with the filter medium and contaminants, reducing the risk of infection, skin irritation, or chemical burns. It also reduces the impact of operator hygiene differences on filter performance, improving consistency after each replacement. Furthermore, since hand contaminants may be introduced into the filtration chamber, contactless replacement makes it easier to maintain stable liquid quality and reduces the probability of secondary contamination.

[0024] like Figures 1 to 5As shown, this utility model provides a urea production filter-type feeding tank that facilitates quick replacement of filter elements. It includes a feeding tank body 1, a slot 2 inside the feeding tank body 1, a rotating groove 3 at the lower end of the slot 2, slots 4 on the upper and lower sides of the rotating groove 3, a locking mechanism 5 fixedly connected within the slots 4, a filter element 6 detachably connected inside the feeding tank body 1, an insert block 7 fixedly connected to the outer surface of the filter element 6, slots 8 on the upper and lower sides of the insert block 7, a conical block 9 fixedly connected to the upper surface of the filter element 6, a positioning block 10 fixedly connected to the outer surface of the conical block 9, a control rod 11, a locking block 12 fixedly connected to the lower surface of the control rod 11, a positioning hole 13 on the locking block 12, and a magnet block 14 fixedly connected to the upper surface of the conical block 9 within the locking block 12.

[0025] Specifically, the locking mechanism 5 includes a mounting plate 51 located on the bottom surface of the slot 4, a spring 52 fixedly connected to the upper surface of the mounting plate 51, a limit plate 53 fixedly connected to the upper surface of the spring 52, and a locking block 54 fixedly connected to the upper surface of the limit plate 53.

[0026] Furthermore, locking block 54 is actively connected to card slot 8.

[0027] Furthermore, a slider 55 is fixedly connected to the outer surface of the limiting plate 53, and a groove is provided in the slot 4. The slider 55 is slidably connected to the groove to prevent the spring 52 from deforming, ensure the linear movement of the locking block 54, and limit the range of motion of the locking block 54.

[0028] It is worth noting that a control handle 15 is fixedly connected to the upper surface of the control lever 11. The control handle 15 is provided with anti-slip texture for gripping the control lever 11.

[0029] It is worth noting that the locking block 12 is movably connected to the conical block 9, and the positioning hole 13 is movably connected to the positioning block 10.

[0030] It is worth mentioning that the insert 7 is slidably connected to the slot 2, and the insert 7 is slidably connected to the rotating groove 3.

[0031] The feeding tank body 1 is existing technology and will not be described in detail here. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail here. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: In use, firstly, the control rod 11 is engaged with the conical block 9 via the locking block 12 and installed on the filter element 6, and positioned by the positioning block 10 and positioning hole 13, while being magnetically fixed by the magnet block 14, thus connecting the control rod 11 and the filter element 6. Then, the control rod 11 controls the filter element 6 to insert the insert 7 on the filter element 6 into the slot 2 on the feeding tank body 1. After inserting it into the bottom of the slot 2, the control rod 11 rotates the filter element 6, thereby rotating the insert 7 on the filter element 6 into the rotating groove 3. Then, the insert 7... The rotating groove 3 rotates and presses through the locking block 54, causing the locking block 54 to engage with the slot 8 on the insert block 7. The spring 52 applies elastic force to the locking block 54, thereby fixing the position of the insert block 7 and thus fixing the position of the filter element 6. When removing the filter element 6, the card block 12 is inserted into the conical block 9, and then the filter element 6 is rotated by the control rod 11, causing the insert block 7 on the filter element 6 to be pressed and released from the locking mechanism 5, and then rotated into the slot 2. Then the filter element 6 can be lifted by the magnetic attraction of the magnet block 14.
