Description

Technical Field

[0001] This utility model relates to the field of grating technology, and in particular to an extraction grating. Background Technology

[0002] Extraction gratings are screening devices commonly used to separate materials and liquids. They are typically made of metal or plastic and feature a special structural design that provides strength and corrosion resistance. Their main characteristic is the presence of numerous irregular holes or grooves in their plate-like structure for filtering and separating materials. As an important industrial equipment component, extraction gratings achieve efficient liquid and solid separation through their unique structural design and working principle. They are widely used in the chemical, pharmaceutical, and food industries, offering advantages such as simple operation, reusability, and wide applicability.

[0003] Existing grating plates are typically semi-circular or double-layer staggered gratings. However, both semi-circular and double-layer staggered gratings suffer from incomplete dispersion of the dispersed phase, resulting in poor product quality, increased production and operating costs, and high oil removal pressure. Furthermore, when installing the grating plate into the extraction clarification tank, it is usually fixed in place using support frames. However, at high flow rates, excessive flow can exert a significant impact on the grating plate, potentially causing it to slide within the extraction clarification tank. This results in uneven liquid distribution on the grating plate, affecting the clarification effect during the extraction process.

[0004] Therefore, how to design a grating that can ensure the stability of the grating within the extraction chamber is a technical problem that engineers need to solve. Utility Model Content

[0005] The purpose of this invention is to provide an extraction grid plate that solves the problems mentioned in the background art.

[0007] Extraction mechanism and stationary mechanism;

[0008] The extraction mechanism includes an extraction clarification chamber and a grid plate. The grid plate is installed inside the extraction clarification chamber and has an organic phase flow channel inside. The bottom of the grid plate and the bottom of the extraction clarification chamber form an aqueous phase flow channel.

[0009] The fixing mechanism includes a fixing plate, a limiting push plate for installing and fixing the position of the grating plate, and an adjusting push plate for adjusting the position of the limiting push plate.

[0010] Preferably, a connecting block is provided on the top of the fixing plate, a connecting frame is rotatably sleeved inside the connecting block, an adjusting slide is provided at the bottom of the connecting frame, and a limit push plate is provided at one end of the adjusting slide.

[0011] Preferably, the other end of the adjusting slide plate is provided with an elastic connecting plate, one end of the elastic connecting plate is provided with an adjusting push plate, the fixed plate is provided with a limiting slide groove, and the adjusting push plate is slidably sleeved inside the limiting slide groove.

[0012] Preferably, the bottom of the fixing plate is provided with an elastic pressure plate, and one end of the elastic pressure plate is provided with a positioning pressure plate. The bottom of the positioning pressure plate is provided with a limit block, and the inside of the adjusting push plate is provided with a limit groove that matches the shape of the limit block.

[0013] Preferably, the limiting card block is fixed inside the limiting card slot, one end of the positioning pressure plate is provided with a toggle plate, and one end of the adjusting push plate is provided with a push plate.

[0015] Preferably, the top of the limiting push plate is provided with a plurality of anti-slip protrusions, the anti-slip protrusions are made of rubber and are distributed in a linear array on the top of the limiting push plate.

[0016] Preferably, the extraction clarification tank is provided with a water inlet pipe and an installation slot, and the grid plate is slidably sleeved inside the installation slot.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this example, by setting up a grid plate, the two phases of extraction are fully mixed in the mixing chamber and then enter the extraction clarification box. The extraction clarification box, together with the grid plate, can effectively enhance the effect of droplet coalescence and achieve effective separation of the two phases. At the same time, the grid plate occupies little space and can effectively block the dispersed phase from entering the aqueous phase until the dispersed phase is thick enough to enter the dispersion absorption channel. This device can reduce the labor intensity of employees, operating costs and oil removal pressure, improve production efficiency, and increase the economic benefits of enterprises.

[0019] In this example, by setting up a fixing mechanism, not only can the position of the grating be fixed, but the fixing force can also be adjusted according to the fixing needs. On the one hand, when the grating is installed into the extraction and clarification tank, the position of the grating can be fixed by the limiting push plate, ensuring the grating's firmness in the extraction and clarification tank. On the other hand, by adjusting the position of the adjusting push plate in the limiting slide groove, the force of the limiting push plate pressing the installation slot can be adjusted to ensure the stability of the grating in the extraction and clarification tank, thus avoiding liquid clarification effect during the grating extraction process.

The connecting block 216 is slidably sleeved inside the connecting groove 107.

[0039] Specifically, the top of the limiting push plate 205 is provided with a plurality of anti-slip protrusions 206, which are made of rubber and are distributed in a linear array on the top of the limiting push plate 205.

[0041] Example 1

[0042] In this embodiment, to solve the problem of incomplete phase separation in the grid plate 102, the technical solution of this embodiment is as follows, for reference. Figures 1 to 8 The grating plate 102 is made of hollow PE board, which is lightweight and easy to install. The organic phase flow channel 103 and aqueous phase flow channel 104 inside the grating plate 102 are S-shaped to enhance the droplet coalescence effect. The organic phase flow channel 103 inside the grating plate 102 is a multi-channel flow channel to facilitate organic clarification. The grating plates 102 are installed inside the extraction clarification tank 101 and are arranged in a linear array. Each extraction clarification tank 101 has three stages of grating plates 102. The distances between the first to third stage grating plates 102 and the bottom of the extraction clarification tank 101 are 300mm, 450mm, and 600mm, respectively. The dispersed phase enters through the S-shaped channel of the grid plate 102, the aqueous phase enters from the bottom and flows backward through the aqueous phase channel 104, and the oil phase flows backward through the organic phase channel 103. The extraction clarification tank 101, together with the grid plate 102, can effectively enhance the effect of droplet coalescence and achieve effective separation of the two phases. At the same time, the grid plate 102 occupies little space and can effectively block the dispersed phase from entering the aqueous phase until the dispersed phase is thick enough to enter the dispersion absorption channel. This device can reduce the labor intensity of employees, operating costs and oil removal pressure, is simple to install and disassemble, requires no maintenance, and improves production efficiency.

[0043] Example 2

[0044] In this embodiment, to address the problem that when the grid plate 102 faces a relatively fast flow rate, the large impact force causes the grid plate 102 to slide within the extraction clarification tank 101, resulting in uneven liquid distribution on the grid plate 102 and affecting the clarification effect during the extraction process, the technical solution of this embodiment is as follows (refer to...). Figures 1 to 8The connecting block 202 is rotatably connected to the connecting frame 203. The limiting push plate 205 is made of sheet metal. Anti-slip protrusions 206 are set on the top of the limiting push plate 205 and are distributed in a linear array. The elastic connecting plate 207 has an arc-shaped curved surface structure. The adjusting push plate 208 is made of sheet metal. The shape of the adjusting push plate 208 is adapted to the shape of the limiting slide groove 210. The adjusting push plate 208 is slidably sleeved inside the limiting slide groove 210. By pushing the adjusting push plate 208, the adjusting push plate 208 slides directionally within the limiting slide groove 210. Driven by the elastic connecting plate 207, The limiting push plate 205 rotates around the connecting block 202, causing the top of the limiting push plate 205 to contact the inner wall of the mounting slot 106, thereby squeezing and positioning the grid plate 102. This ensures the grid plate 102 is firmly in the extraction clarification tank 101. Then, by adjusting the position of the adjusting push plate 208 in the limiting slide groove 210, the force of the limiting push plate 205 squeezing the mounting slot 106 is adjusted to ensure the stability of the grid plate 102 in the extraction clarification tank 101, thus avoiding liquid clarification during the extraction process of the grid plate 102.

[0045] As a further limitation of this technical solution, the elastic pressure plate 211 has an arc-shaped elastic curved surface structure. The elastic pressure plate 211 and the positioning pressure plate 212 are an integral structure. The shape of the limiting block 213 is adapted to the shape of the limiting slot 214. Under the action of the elastic pressure plate 211, the positioning pressure plate 212 contacts the top of the adjusting push plate 208, and at the same time, the limiting block 213 is fixedly sleeved in the limiting slot 214, thereby limiting the position of the adjusting push plate 208 and ensuring the stability of the grid plate 102 in the extraction clarification tank 101. The actuating arc plate 215 has an arc-shaped curved surface structure. The actuating arc plate 215 and the positioning pressure plate 212 are an integral structure. When it is necessary to adjust the position of the adjusting push plate 208 in the limiting slide groove 210, the position of the actuating arc plate 215 can be adjusted to separate the limiting block 213 from the limiting slot 214, thereby adjusting the position of the adjusting push plate 208.

[0046] It should be noted that the shape of the fastening block 216 is adapted to the shape of the fastening slot 107. By sliding the fastening block 216 into the fastening slot 107, it is easy to install the fixing mechanism 2 onto the outside of the grating plate 102.

[0047] Based on the above embodiments, it can be concluded that when using the grating plate 102 for extraction, by sliding the connecting block 216 into the connecting groove 107, it is convenient to install the fixing mechanism 2 onto the outside of the grating plate 102. Then, the grating plate 102 is installed into the mounting groove 106 provided in the extraction clarification tank 101. Then, by pushing the adjusting push plate 208, the adjusting push plate 208 slides directionally within the limiting slide groove 210. Under the drive of the elastic connecting plate 207, the limiting push plate 205 rotates around the connecting block 202, so that the top of the limiting push plate 205 contacts the inner wall of the mounting groove 106, thereby squeezing and positioning the grating plate 102, which can ensure the firmness of the grating plate 102 in the extraction clarification tank 101. Then, by adjusting... The position of the pusher plate 208 within the limiting slide groove 210 is adjusted to control the force of the limiting pusher plate 205 pressing the mounting slot 106, ensuring the stability of the grid plate 102 in the extraction clarification tank 101. This avoids liquid clarification during the extraction process of the grid plate 102. After the two phases are fully mixed in the mixing chamber, they enter the extraction clarification tank 101 through the water inlet pipe 105. The extraction clarification tank 101, in conjunction with the grid plate 102, can effectively enhance the effect of droplet coalescence and achieve effective separation of the two phases. At the same time, the grid plate 102 occupies little space and can effectively block the dispersed phase from entering the aqueous phase until the dispersed phase is thick enough to enter the dispersion absorption channel. This device can reduce the labor intensity of employees, operating costs, and oil removal pressure, and improve production efficiency.
