Description

Technical Field

[0001] This utility model belongs to the technical field of microfiltration machines, specifically an improved tracked filtration system microfiltration machine. Background Technology

[0002] In industrial sectors such as aquaculture, food processing, and wastewater treatment, microfiltration machines are widely used as important solid-liquid separation equipment to remove suspended particles and organic impurities from water. Among them, the tracked filtration system microfiltration machine is particularly favored because it can achieve continuous filtration and automatic sludge removal.

[0003] Publication number CN120698560A discloses a microfilter of a tracked filtration system. This patent is also an invention of the applicant. It achieves continuous filtration of water and automatic removal of impurities through a structure such as a circulating conveyor belt filter screen and scraper assembly, demonstrating good working performance.

[0004] However, in practice, it was found that there is still room for further optimization of this existing technology, mainly in the following aspects: The existing equipment lacks an effective water flow buffer structure. When a large flow of sewage impacts the filter screen, it is very easy for the filter screen to be "burst" through, causing some small impurities (such as fish feces) to not be intercepted and directly enter the clean area or fish feces tank, which seriously affects the quality of the effluent.

[0005] The entire device lacks water level detection, making it impossible to monitor filter clogging in real time. Operators must rely on experience to periodically start flushing, which can easily lead to untimely or frequent flushing.

[0006] Traditional scraper assemblies are mostly rigid designs, which cannot maintain a dynamic and tight fit with the flexible filter screen during operation, which can easily lead to incomplete scraping.

[0007] Therefore, this application is a targeted improvement and innovation based on the above-mentioned prior art, aiming to provide an improved tracked filtration system microfilter with higher filtration efficiency and more stable operation. Utility Model Content

[0008] To address the above problems, this utility model provides an improved tracked filtration system microfilter to solve the technical problems in the background art.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An improved tracked microfiltration system includes a housing, a right guard plate, a left guard plate, a mesh plate, a conveyor belt filter screen, a baffle plate, a housing cover plate, an outlet cover plate, an outlet, and a drive device. A first roller is rotatably mounted on the opposite side of the outlet, and a second roller is rotatably mounted on the side end of the first roller. The first and second rollers are arranged in a staggered pattern. A water level detector is mounted on the inner side of the baffle plate via a bracket. A scraper assembly is mounted on the side end of the conveyor belt filter screen. The scraper assembly includes a support plate, and a scraper is mounted on the upper side end of the support plate. The scraper is compatible with the conveyor belt filter screen.

[0010] As a further improvement to the above solution, the support plate includes a plate body, with a flow guide plate provided at the lower end of one side of the plate body; bolts are provided on both sides of the plate body, with one end of the bolt passing through the plate body and inserted into the first spring, and the other side of the first spring being inserted into the connecting block; the support plate is connected to the right guard plate and the left guard plate through connecting ears and bolts; the scraper is a rubber plate that is attached to the conveyor belt filter screen.

[0011] As a further improvement to the above scheme, the first roller is inserted into the oppositely arranged mounting plate through a rotating shaft. The mounting plate is located on the two inner sides of the baffle plate. The mounting plate includes a mounting block and a second inclined plate. The mounting block is connected to the baffle plate by bolts.

[0012] As a further improvement to the above solution, an ultraviolet lamp assembly is provided on the lower side of one end of the right guard plate and the left guard plate. The ultraviolet lamp assembly includes an ultraviolet lamp body, one side of which is set on the end plate and the other side is set in the sleeve. The side end of the sleeve is inserted through the right guard plate or the left guard plate and is provided with a handle. The handle is connected to the right guard plate or the left guard plate by bolts.

[0013] As a further improvement to the above scheme, the outlet includes a side plate and an arc plate, and a drop plate is provided on the arc plate; the drop plate and the first inclined plate of the outlet cover plate form a duckbill-shaped outlet, and the first inclined plate is provided on the side end of the top plate.

[0014] As a further improvement to the above solution, one of the conveyor shafts of the conveyor belt filter screen is set inside the slider of the alignment and tensioning device. The slider is slidably set inside the guide rail frame. One side of the slider is connected to the connecting rod. A limit block is set in the middle of the connecting rod. The end of the connecting rod is set inside the vertical block. A second spring is inserted through the connecting rod and is set between the limit block and the vertical block. Screws are set at the upper and lower ends of the connecting rod. The two sides of the screws are respectively set inside the guide rail frame and the vertical block.

[0015] As a further improvement to the above solution, a fish manure bin is provided on the lower side of the scraper assembly, and a filter cotton bin is provided directly below the conveyor belt filter screen. The fish manure bin and the filter cotton bin are designed as separate structures and are located at the lower end of the box.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an improved tracked filtration system microfilter, which adds two plum blossom-shaped first and second rollers to block the water flow. The double-layered blocking of the rollers can prevent the water from directly rushing into the fish feces chamber due to excessive water flow. The two water flow blocking will not hinder fish feces and impurities (the front roller can rotate, and the rear roller can also rotate, which can ensure that fish feces and impurities pass through smoothly). While blocking the water flow, the rollers can also raise the water level above the filter screen. The higher the water level, the higher the water flow rate and the less frequent the rinsing. A water level detector has been added to the baffle plate. When the water level reaches a certain position, the water level detector sends a signal to the controller to start the high-pressure flushing water pump to clean the filter screen and prevent the filter screen from clogging and overflowing due to excessive water level. The scraper assembly on the side of the conveyor belt filter screen has an arc-shaped scraper plate that matches the arc shape of the lower end of the conveyor belt filter screen. This allows the scraper to fit more closely to the conveyor belt filter screen and remove impurities, thus improving efficiency.

[0017] The scraper plate is fixed by bolts and springs, which makes it easier for the scraper plate and the conveyor belt filter screen to fit together, scraping off the impurities attached to the screen and into the fish manure bin. The first roller is inserted into the opposite mounting plate via a rotating shaft. The mounting plate includes a mounting block and a second inclined plate. The mounting block has the function of fixing the first roller, and the second inclined plate has the function of guiding the flow. One end of the ultraviolet lamp assembly is set on the end plate, and the other end is set inside the sleeve. The side end of the sleeve is inserted through the right or left protective plate and has a handle, which makes it easy to pull out the ultraviolet lamp body. The outlet includes a side plate and an arc-shaped plate, with a drop plate installed on the arc-shaped plate to increase the water level difference. The alignment and tensioning device makes it easy to adjust the tension of the conveyor belt filter screen. The fish waste bin and filter cotton bin are designed as separate units and located at the bottom of the box, making it easy to remove them as needed and improving ease of use.

The scraper 25 is connected to the plate body 211 by bolts.

[0031] like Figure 5 As shown, in a preferred embodiment, the first roller 20 is inserted into the opposing mounting plate 30 via a rotating shaft. The mounting plate 30 is located on both inner sides of the baffle plate 7. The mounting plate 30 includes a mounting block 301 and a second inclined plate 302. The mounting block 301 is bolted to the baffle plate 7. The first roller 20 is fixed within the mounting block 301 of the mounting plate 30 via a fixed shaft, thereby achieving reliable positioning and flexible rotation of the first roller 20.

[0032] like Figure 8As shown in the preferred embodiment, an ultraviolet lamp assembly 6 is provided on the lower side of one end of the right guard plate 3 and the left guard plate 13. The ultraviolet lamp assembly 6 includes an ultraviolet lamp body 61. One side of the ultraviolet lamp body 61 is disposed on the end plate 63, and the other side is disposed in the sleeve 62. The side end of the sleeve 62 is inserted through the right guard plate 3 or the left guard plate 13 and is provided with a handle 64. The handle 64 is connected to the right guard plate 3 or the left guard plate 13 by bolts. The ultraviolet lamp assembly 6 sterilizes the filtered water, improves water quality, and meets the health requirements of aquaculture water. The handle 64 is designed for convenient, quick, and safe installation, disassembly, and maintenance of the ultraviolet lamp tube. When it is necessary to replace or clean the ultraviolet lamp tube, first remove the bolts connecting the handle 64 to the right guard plate 3 or the left guard plate 13. Simply operate the handle 64 to loosen one end of the sleeve 62, and the entire ultraviolet lamp can be pulled out from one side. During installation, insert one end of the lamp tube into the end plate 63, align the sleeve 62 at the other end with the hole on the protective plate, and push it in. Then tighten the handle 64 to secure it. The handle 64 is connected to the protective plate by bolts.
