Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to an impurity filtration device. Background Technology

[0002] Blended oil is made by mixing various vegetable oils together in a blending tank in a certain proportion. Vegetable oils include soybean oil, rapeseed oil, sesame oil, peanut oil, etc. Vegetable oils are usually temporarily stored in the crude oil tank and are usually filtered to remove impurities before entering the blending tank inlet, thus reducing the impurity content of the blended oil. Traditional filtration devices usually rely solely on the filter holes at the bottom of the filter barrel or the filter holes on the flat plate filter plate for filtration. The small filtration area leads to low filtration efficiency, which cannot meet the needs of high-efficiency production. When the bottom or part of the side wall becomes blocked, filtration can no longer continue, so the filter holes of the filter barrel cannot be fully utilized, resulting in a short service life of the filter barrel and poor filtration effect. Utility Model Content

[0003] In view of this, the present invention provides an impurity filtration device, which solves the problem that traditional filtration devices usually rely solely on the filter holes at the bottom of the filter barrel or on the filter plate for filtration. This results in a small filtration area, low filtration efficiency, and an inability to meet the needs of high-efficiency production. Furthermore, when the bottom or a portion of the side wall becomes blocked, filtration can no longer continue, and the filter holes in the filter barrel cannot be fully utilized, leading to a short service life and poor filtration effect.

[0004] To solve the above-mentioned technical problems, this utility model provides an impurity filtration device, including a transfer tank connected to the discharge port of the production device for the liquid to be filtered. A sealing cap is provided on the upper part of the transfer tank, and a feed inlet is provided on the side wall of the transfer tank. A filter tank is detachably installed inside the transfer tank. Multiple filter holes are provided on the side wall and bottom of the filter tank. The height of the side of the filter tank closest to the feed inlet is below the feed inlet. A connecting piece is provided between the filter tank and the sealing cap. This utility model can achieve efficient filtration of the liquid to be filtered through the filter holes on the side wall and bottom of the filter tank, greatly extending the service life of the filter tank. Simultaneously, when the filter tank is clogged, the sealing cap can be removed to simultaneously remove the filter tank for efficient cleaning, greatly improving the filtration efficiency of the filter tank and making operation more convenient.

[0005] Clamps are installed between the sealing cap and the transfer barrel, as well as between the discharge port and the inlet. This utility model can achieve a detachable connection for quick sealing of the connection parts through clamps, which greatly improves the efficiency of maintenance and disassembly.

[0006] The connector includes a connecting rod located at the bottom of the sealing cover, and a support plate located at the bottom of the connecting rod. The support plate is located inside the filter bucket, and its two ends are respectively set together with the inner side wall of the filter bucket. This utility model can achieve an integrated design and firm connection between the filter bucket and the sealing cover through the connector. It can also remove the filter bucket into the transfer bucket for cleaning and maintenance when the sealing cover is removed, making the operation more convenient.

[0007] A transparent observation window is also provided on the side wall of the transfer tank. This utility model allows for real-time monitoring of the filtration status of the filter canister inside the transfer tank through the transparent observation window, facilitating timely removal and cleaning of clogged filter canisters, making the process more convenient.

[0008] The height of the filter barrel on the side with the feed inlet is lower than that on the side with the transparent observation window. This is to facilitate the efficient and complete utilization of the filter holes on the side wall of the filter barrel, and to avoid the filter barrel becoming clogged at the bottom or part of its height, which would prevent the filtration operation from continuing and greatly extend the service life of the filter barrel.

[0009] The bottom of the transfer tank is equipped with a discharge port, which facilitates the efficient discharge and collection of the material filtered by the filter tank or for further processing.

[0010] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0011] 1. High-efficiency filtration and improved efficiency: This utility model increases the filtration area by setting multiple filter holes on the side wall and bottom of the filter tank, which can realize high-efficiency filtration of the liquid to be filtered, effectively solving the problem of low filtration efficiency caused by small filtration area in the prior art, and greatly improving filtration efficiency.

[0012] 2. Easy disassembly and maintenance: This invention utilizes clamps installed between the resealing cap and the transfer tank, as well as between the discharge port and the inlet connecting pipe, to achieve quick sealing and detachable connection at the joints. When the filter tank becomes clogged, the sealing cap can be easily removed, and the filter tank can be simultaneously removed for cleaning using the connecting parts. This solves the problems of cumbersome filter tank disassembly and low maintenance efficiency in existing technologies, significantly improving the efficiency of maintenance and disassembly.

[0013] 3. Real-time observation and timely handling: This utility model allows for real-time monitoring of the filtration status of the filter barrel inside the transfer tank through a transparent observation window set on the side wall of the transfer tank. This facilitates operators in promptly identifying and cleaning any blockages in the filter barrel, preventing interruptions in the filtration operation due to the inability to detect blockages in time, and ensuring the continuous operation of the filtration process.

[0014] 4. Full utilization and extended lifespan: This utility model can set the height of the filter barrel on the side of the feed inlet to be lower than the height of the filter barrel on the side of the transparent observation window, so that the liquid in the filter barrel can rise gradually, making full use of the filter holes at different heights on the side wall of the filter barrel. This avoids the problem of the filtration operation being unable to continue due to blockage at the bottom or part of the side wall of the filter barrel, and greatly extends the service life of the filter barrel.

[0020] like Figure 1-3As shown: This embodiment provides an impurity filtration device, including a transfer tank 100 connected to the discharge port of the production device for the liquid to be filtered. The transfer tank 100 is made of 304 stainless steel, which has good corrosion resistance and strength and can adapt to various liquid environments. A sealing cover 200 is provided on the upper part of the transfer tank 100. The sealing cover 200 is also made of 304 stainless steel and cooperates with the transfer tank 100 to achieve a seal, preventing liquid leakage and impurities from entering.

The filter tank 300 is made of high-strength polypropylene, which has good chemical stability and filtration performance. Multiple filter holes 301 are provided on the side wall and bottom of the filter tank 300. Made of polypropylene, it has good chemical stability and filtration performance. The diameter of the filter hole 301 is set according to the size of the impurities in the liquid to be filtered, for example, it can be set to 0.1-1mm. The height of the side of the filter barrel 300 near the feed inlet 101 is below the feed inlet 101. A connecting piece 400 is provided between the filter barrel 300 and the sealing cover 200. This utility model can achieve efficient filtration of the liquid to be filtered through the filter holes 301 on the side wall and bottom of the filter barrel 300, which greatly improves the service life of the filter barrel 300. At the same time, when the filter barrel 300 is clogged, the sealing cover 200 can be removed at the same time to simultaneously remove the filter barrel 300, which is convenient for efficient cleaning and greatly improves the filtration efficiency of the filter barrel 300, making operation more convenient.

[0021] According to one embodiment of the present invention, such as Figure 1-3 As shown, clamps 500 are installed between the sealing cap 200 and the transfer tank 100, as well as between the connecting pipes of the discharge port and the inlet port 101. The clamps 500 are made of stainless steel strip and are ratchet-type ring clamps (product number HD679) manufactured by Tianjin Heding Industry & Trade Co., Ltd., made of 304 stainless steel and conforming to standard Q / HD 02-002-2010. These clamps 500 feature 360° locking and non-destructive hose installation, possessing good elasticity and sealing performance.

[0022] According to another embodiment of the present invention, such as Figure 1 and Figure 2As shown, the connector 400 includes a connecting rod 401 located at the lower part of the sealing cover 200. The connector 400 is made of 45# steel to ensure the firmness of the connection. A support plate 402 is provided at the lower part of the connecting rod 401. The support plate 402 is located inside the filter barrel 300, and its two ends are welded to the inner sidewall of the filter barrel 300, respectively, to realize the integral connection between the filter barrel 300 and the sealing cover 200. This utility model can realize the integral design and firm connection between the filter barrel 300 and the sealing cover 200 through the connector 400. It can also make it possible to remove the filter barrel 300 into the transfer barrel 100 for cleaning and maintenance when the sealing cover 200 is removed, making the operation more convenient.

[0023] According to another embodiment of the present invention, such as Figure 2 and Figure 3 As shown, a transparent observation window 600 is also provided on the side wall of the transfer tank 100. The transparent observation window 600 is made of tempered glass, which has high strength and transparency, making it easy to observe the internal filtration status.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the bottom of the transfer tank 100 is provided with a discharge port 102, which facilitates the efficient discharge and collection of the material filtered by the filter tank 300 or for further processing.

[0026] How to use this utility model:

[0027] First, it needs to be clarified that the filtration device involved in this utility model is mainly used for filtering impurities in liquids. This utility model takes the impurities in the production process of blended oil as an example to describe its working principle and usage method in detail. For the purposes of this application, the liquid to be filtered is blended oil, and its production equipment usually includes equipment such as blended oil tanks. The blended oil is discharged from the outlet 102 of the blended oil tank and connected to the inlet 101 of the transfer tank 100 through a conveying pipeline. In actual production, a conveying pump, such as a centrifugal pump, can be installed on the conveying pipeline. The centrifugal force generated by the rotation of the impeller of the centrifugal pump is used to draw the blended oil from the blended oil tank and pressurize it, so that it overcomes the pipeline resistance and smoothly enters the filter tank 300 inside the transfer tank 100 through the inlet 101. In addition, a flow control valve, such as a butterfly valve, can be installed on the conveying pipeline. By adjusting the opening of the butterfly valve, the flow rate of the blended oil entering the transfer tank 100 can be precisely controlled to adapt to different production needs and filtration efficiencies. Since the core improvement of this utility model lies in how to increase the service life of the filter tank 300, the conveying principle of the blended oil will not be described in detail. It can be achieved using existing equipment. The working principle of this utility model is as follows:

[0028] The liquid to be filtered is discharged from the discharge port of the production unit and enters the filter tank 300 inside the transfer tank 100 through the inlet 101 via a connecting pipe. Since the filter tank 300 has multiple filter holes 301 on its side walls and bottom, the liquid to be filtered passes through these filter holes 301 under its own gravity, and impurities are trapped inside the filter tank 300. The filtered liquid then enters the gap between the transfer tank 100 and the filter tank 300. Finally, the filtered liquid is discharged through the outlet 102 at the bottom of the transfer tank 100 and can be directly collected or transported to the next process.

[0029] The usage method is as follows:

[0030] Installation: Place the filter bucket 300 inside the transfer bucket 100, and securely connect the filter bucket 300 to the sealing cover 200 using the connector 400. Cover the filter bucket 300 with the sealing cover 200 and secure it to the transfer bucket 100 with the clamp 500. Connect the discharge port of the production device to the inlet 101 of the transfer bucket 100 through a connecting pipe and secure it with the clamp 500.

[0031] Filtration: The production unit is turned on, and the liquid to be filtered enters the filter tank 300 through the discharge port, connecting pipe, and feed port 101 for filtration. The operator can observe the filtration process in real time through the transparent observation window 600.

[0032] Cleaning and Maintenance: When the filter cartridge 300 is found to be clogged or the filtration efficiency has significantly decreased through the transparent observation window 600, shut down the production unit, loosen the clamp 500 between the sealing cover 200 and the transfer tank 100, remove the sealing cover 200, and use the connecting piece 400 to remove the filter cartridge 300 together with the transfer tank 100 to clean the impurities inside the filter cartridge 300. After cleaning, put the filter cartridge 300 back into the transfer tank 100 and reset it according to the installation steps to continue the filtration operation.

[0033] This invention solves the problem that traditional filtration devices typically rely solely on the filter holes 301 at the bottom or on the flat filter plate for filtration. This results in a small filtration area, low filtration efficiency, and an inability to meet the demands of high-efficiency production. Furthermore, when the bottom or a portion of the sidewall becomes clogged, filtration cannot continue, leading to insufficient utilization of the filter holes 301, a short lifespan for the filter, and poor filtration performance.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
