Description

Technical Field

[0001] This utility model relates to the field of calcium formate technology, and in particular to a rapid filtration structure for a calcium formate crystallization and separation device. Background Technology

[0002] Calcium formate is a white crystalline or powdery chemical substance with the molecular formula Ca(HCOO)2. It is highly soluble in water and is commonly used as a feed additive to provide calcium for livestock and poultry, promoting growth and bone development. In addition, calcium formate can also be used as a food preservative, antifungal agent, and industrial retarder and early-strength agent. It is stable, safe and non-toxic, and has a wide range of applications in many fields. It is an important raw material in the chemical, food and feed industries.

[0003] For example, Chinese patent CN216755446U discloses a calcium formate purification device, which proposes "including a box, a feed pipe, a liquid inlet pipe and a filtration mechanism, with a feed pipe inserted on the left side above the box and a liquid inlet pipe inserted on the right side above the box, and a baffle installed inside the box".

[0004] During the separation of calcium formate, rotation causes calcium formate crystals to remain inside the rotating chamber. However, with prolonged rotation and filtration, the calcium formate crystals inside are not discharged in time. As the number of calcium formate crystals increases, the pores are easily blocked by the accumulated calcium formate crystals, resulting in a continuous decrease in filtration efficiency and affecting separation efficiency. Therefore, this utility model proposes a rapid filtration structure for a calcium formate crystallization separation device to solve the above problems. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a rapid filtration structure for a calcium formate crystallization separation device. This solves the problem in the prior art where the increase in calcium formate crystals leads to the gradual blockage of pores by accumulated calcium formate crystals, resulting in a continuous decline in filtration efficiency and affecting separation efficiency.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a rapid filtration structure for a calcium formate crystallization separation device, comprising a cylinder, a feed pipe, a liquid outlet pipe, a discharge pipe, a top cover, a collection hopper, and a filter cylinder. The feed pipe is connected to the right side of the top of the cylinder, and the liquid outlet pipe is connected to the left side of the bottom of the cylinder.

[0007] A further improvement is made in that: the scraping mechanism includes a rotating shaft, clamps, a telescopic rod, a scraper, a spring, and an adjusting nut. The bottom of the feed pipe is rotatably connected to the rotating shaft. Multiple clamps are provided on the outer side of the rotating shaft. A telescopic rod is fixedly connected to the outer wall of the clamps. A scraper is fixedly connected to one end of the telescopic rod. One side of the scraper is in close contact with the inner wall of the filter cylinder. A spring is provided on the outer wall of the telescopic rod. An adjusting nut is threadedly connected to the outer wall of the telescopic rod.

[0008] A further improvement is that one end of the spring is fitted and connected to one side of the scraper, and the other end of the spring is fitted and connected to one side of the adjusting nut, and the diameter of the adjusting nut is larger than the diameter of the spring.

[0009] A further improvement is that the clamp is designed as two separate structures, and the shape is an arc block. A set of connecting bolts is symmetrically inserted on both sides of one of the arc blocks, and one end of the connecting bolt passes through the interior of the other arc block and is threaded with a connecting nut.

[0010] A further improvement is that the rotating mechanism includes a motor and a coupling, a support frame is fixedly connected to the top of the top cover, a motor is fixedly installed on the top of the support frame, and the output end of the motor is fixedly connected to the top of the rotating shaft through the coupling.

[0011] A further improvement is that the shape of the collecting hopper is designed to be wider at the top and narrower at the bottom, with the top of the collecting hopper being fitted and connected to the bottom of the filter cylinder, and a solenoid valve being fixedly installed inside the discharge pipe.

[0012] A further improvement is that an extension head is fixedly connected to one end of the feed pipe, and one end of the extension head is located above the filter cylinder, while one end of the liquid outlet pipe is parallel to the bottom end of the filter cylinder.

One side of the scraper is attached to the inner wall of the filter cylinder, and the rotation range of multiple scrapers covers the entire filter cylinder to clean the crystals inside the entire filter cylinder, ensuring the filtration effect of the filter cylinder. The telescopic rod can be adjusted in length according to the actual size of the filter cylinder.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a rapid filtration structure for a calcium formate crystallization separation device, including a cylinder 1, a feed pipe 2, a liquid outlet pipe 3, a discharge pipe 4, a top cover 5, a collection hopper 6, and a filter cylinder 8. The feed pipe 2 is connected to the right side of the top of the cylinder 1, and the liquid outlet pipe 3 is connected to the left side of the bottom of the cylinder 1. The collection hopper 6 is fixedly connected to the bottom of the cylinder 1, and the discharge pipe 4 is connected to the bottom of the collection hopper 6. The filter cylinder 8 is fixedly installed inside the cylinder 1, and a scraping mechanism matching the filter cylinder 8 is provided inside the cylinder 1. The top cover 5 is fixedly installed on the top of the cylinder 1, and the top of the top cover 5 is provided with a scraping mechanism. The device is equipped with a matching rotating mechanism. During use, the solution containing calcium formate crystals is fed into the cylinder 1 through the feed pipe 2. The filter cylinder 8 inside the cylinder 1 acts as a filter, separating the crystals from the solution. The crystals fall into the collection hopper 6 and are discharged to the outside of the cylinder 1 through the solenoid valve 7. The solution is discharged to the outside of the cylinder 1 through the outlet pipe 3. After long-term operation, a large number of crystals accumulate in the filter holes of the filter cylinder 8, affecting the filtration effect. The rotating mechanism drives the scraping mechanism to rotate inside the filter cylinder 8, which can scrape the crystals inside the filter cylinder 8 into the collection hopper 6 to ensure the filtration effect of the filter cylinder 8.

[0020] The scraping mechanism includes a rotating shaft 9, a clamp 10, a telescopic rod 11, a scraper 12, a spring 13, and an adjusting nut 14. The clamp 10 is designed as two separate structures, shaped as arc blocks. A set of connecting bolts 15 are symmetrically inserted on both sides of one arc block. One end of the connecting bolt 15 passes through the interior of the other arc block and is threaded with a connecting nut. The two arc blocks are respectively attached to both sides of the rotating shaft 9. Then, the two sets of connecting bolts 15 are respectively inserted into both sides of one arc block, with one end of the connecting bolt 15 passing through the interior of the other arc block. The connecting nut is tightened at the through end, and the two arc blocks are clamped together by the connecting nut, so as to connect the clamp 10 and the rotating shaft 9 as a whole.

[0021] The rotating mechanism includes a motor 16 and a coupling 17. A support frame is fixedly connected to the top of the top cover 5, and a motor 16 is fixedly installed on the top of the support frame. The output end of the motor 16 is fixedly connected to the top end of the rotating shaft 9 through the coupling 17. The top end of the rotating shaft 9 is connected to the output end of the motor 16 through the coupling 17 to form a whole. The output end of the motor 16 can drive the rotating shaft 9 to rotate inside the cylinder 1.

[0022] A rotating shaft 9 is rotatably connected to the bottom of the feed pipe 2. Multiple clamps 10 are provided on the outer side of the rotating shaft 9. A telescopic rod 11 is fixedly connected to the outer wall of each clamp 10. A scraper 12 is fixedly connected to one end of the telescopic rod 11. One side of the scraper 12 is fitted against the inner wall of the filter cylinder 8. A spring 13 is provided on the outer wall of the telescopic rod 11. An adjusting nut 14 is threadedly connected to the outer wall of the telescopic rod 11. One end of the spring 13 is fitted against one side of the scraper 12, and the other end of the spring 13 is fitted against one side of the adjusting nut 14. The diameter of the adjusting nut 14 is larger than the diameter of the spring 13. The scraper 12 is connected to the rotating shaft 9 as a single unit via the clamps 10. The scraper 12 can rotate inside the filter cylinder 8. One side of the scraper 12 is attached to the inner wall of the filter cylinder 8, and the rotation range of multiple scrapers 12 covers the entire filter cylinder 8 to clean the crystals inside the entire filter cylinder 8, ensuring the filtration effect of the filter cylinder 8. The telescopic rod 11 can be adjusted in length according to the actual size of the filter cylinder 8. The adjusting nut 14 on the outside of the telescopic rod 11 can also be tightened. The adjusting nut 14 compresses the spring 13 to the limit position. The elastic force generated by the spring 13 presses the scraper 12 tightly inside the filter cylinder 8, ensuring the effect of the scraper 12 in scraping crystals. When the scraper 12 and the filter cylinder 8 are worn, the adjusting nut 14 can be tightened again to ensure the service life of the scraper 12.

[0023] The hopper 6 is designed to be wider at the top and narrower at the bottom. The top of the hopper 6 is connected to the bottom of the filter cylinder 8. A solenoid valve 7 is fixedly installed inside the discharge pipe 4. When the crystal falls to the bottom of the hopper 6, the structure of the hopper 6 is used to concentrate the crystal at the bottom of the hopper 6 and it enters the discharge pipe 4. The solenoid valve 7 on the discharge pipe 4 is opened, and the crystal is discharged to the outside through the discharge pipe 4.

[0024] One end of the feed pipe 2 is fixedly connected to an extension head, and one end of the extension head is located above the filter cylinder 8. One end of the outlet pipe 3 is parallel to the bottom end of the filter cylinder 8. The solution with calcium formate crystals precipitated can be conveyed into the filter cylinder 8 through the extension head of the feed pipe 2. The solution filtered out by the filter cylinder 8 flows downward by gravity and then flows to the outside through the outlet pipe 3. The crystals fall into the collection hopper 6.

[0025] In this filter structure, the top end of the rotating shaft 9 is connected to the output end of the motor 16 via a coupling 17. The output end of the motor 16 can drive the rotating shaft 9 to rotate inside the cylinder 1. The scraper 12 is connected to the rotating shaft 9 via a clamp 10. The rotating shaft 9 can drive the scraper 12 to rotate inside the filter cylinder 8. One side of the scraper 12 is attached to the inner wall of the filter cylinder 8, and the rotation range of multiple scrapers 12 covers the entire filter cylinder 8 to clean the crystals inside the entire filter cylinder 8, ensuring the filtration effect of the filter cylinder 8. The telescopic rod 11 can be adjusted in length according to the actual size of the filter cylinder 8. The adjusting nut 14 on the outside of the telescopic rod 11 can also be tightened. The adjusting nut 14 compresses the spring 13 to the limit position, and the elastic force generated by the spring 13 presses the scraper 12 tightly inside the filter cylinder 8, ensuring the effect of the scraper 12 scraping crystals. When the scraper 12 and the filter cylinder 8 are worn out, the adjusting nut 14 can be tightened again to ensure the service life of the scraper 12.
