Description

Technical Field

[0001] This utility model mainly relates to the technical field of filter presses, specifically a filter press liquid receiving device. Background Technology

[0002] In the rice bran oil processing, the filter press is a key piece of equipment for the purification and pretreatment of crude rice bran oil (virgin rice bran oil). The core principle is "pressure drive + filter media interception" to remove impurities such as rice bran residue, colloids, and pigment particles from the crude oil, providing a clean oil source for subsequent deep refining processes such as deacidification and deodorization. This improves the transparency, stability, and food safety of the finished oil, while reducing the consumption of reagents and refining losses in subsequent processes. Common types are mainly plate and frame filter presses and chamber filter presses. The plate and frame filter press consists of filter plates and filter frames arranged alternately, which has high filtration accuracy and low cost, making it suitable for small and medium-sized processing plants.

[0003] In the operating system of filter presses (especially for fluid filtration scenarios such as rice bran oil, chemicals, and food), the filter press liquid receiving device is specifically used to collect, guide, temporarily store, or transport the "target fluid" (such as purified oil in rice bran oil processing) generated during the filtration process. Its core function is to prevent fluid leakage, ensure the clean collection of the filtered products, and connect the filter press with subsequent process equipment (such as purified oil tanks and wastewater treatment systems) to achieve a closed loop in the production process. It mainly includes a guide plate and a liquid receiving tank. The guide plate directly receives the purified oil flowing out of the filter plate / filter frame, preventing oil from dripping onto the ground, and guides this purified oil into the liquid receiving tank for collection. To ensure filtration efficiency and product quality, the filter cloth needs to be cleaned regularly. The wastewater from the cleaning will enter the receiving tank through the guide plate and then be cleaned in a centralized manner. This means that the receiving tank also needs to collect wastewater during the cleaning process. Sometimes, if the receiving tank is not cleaned thoroughly, wastewater residue will remain, which will contaminate the subsequent oil purification. Alternatively, the receiving tank can be replaced with another one to collect the wastewater. However, since the receiving tank is long and heavy, it needs to be moved out from the bottom of the filter press when replacing it, which is also very inconvenient. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model provides a filter press liquid receiving device to solve the technical problem mentioned in the background art, where the liquid receiving tank not only collects purified oil but also collects wastewater during the cleaning process, which easily leads to purified oil contamination during the later stages of purified oil collection.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A filter press liquid receiving device includes a plate and frame body and a guide-type liquid receiving mechanism below the plate and frame body. The guide-type liquid receiving mechanism includes a guide plate, a liquid receiving tank, a wastewater tank, and multiple lead screws. The guide plate is located below the filter plate of the plate and frame body. The liquid receiving tank and the wastewater tank are located on both sides below the guide plate. A guide frame is bolted to the lower side of the guide plate. The multiple lead screws are arranged linearly at equal intervals. Each lead screw is provided with a nut seat. Each nut seat is provided with a detachable guide block. The guide block and the guide frame are slidably connected.

[0006] Furthermore, the guide plate includes a transition section, a guide section, and a limiting section, with the guide section located on both sides of the transition section and the limiting section located on both sides of the flow guide surface formed by the guide section and the limiting section.

[0007] Furthermore, a support shaft is provided in the circular hole on the guide plate. The support shaft is attached to the bracket of the plate frame body. Limit sleeves are provided at both ends of the support shaft. The limit sleeves and the bracket of the plate frame body are connected by bolts.

[0008] Furthermore, the guide frames are linearly distributed at equal intervals on both sides of the lower surface of the guide plate. Each guide frame includes a mounting part, a connecting part, and a slide rail part, and the slide rail part and the inclined surface on the corresponding guide block are slidably connected.

[0009] Furthermore, each of the lead screws is provided with a pulley, and adjacent pulleys on different lead screws are connected by a belt.

[0010] Furthermore, each of the lead screws has a support frame fitted at both ends of its outer edge, and the round hole on the support frame is rotatably connected to the lead screw.

[0011] Furthermore, the guiding liquid receiving mechanism also includes a motor, the output end of which is connected to one end of one of the lead screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the design of a guide plate, a liquid receiving tank, a wastewater tank, a lead screw, a nut seat, a guide block, a guide frame, a support shaft, a motor, and a pulley, achieves the goal of immediate physical isolation between clean oil and wastewater by utilizing the coordinated design of a switchable guide plate and independent liquid receiving tank and wastewater tank. This avoids the risk of wastewater residue remaining on the inner wall of the liquid receiving tank in the prior art, leading to cross-contamination of the clean oil in the subsequent process. It can ensure the cleanliness of the clean oil without relying on frequent cleaning of the liquid receiving tank, and is especially suitable for the hygiene precision requirements of food-grade oil processing such as rice bran oil. In addition, the slope of the guide plate can be adjusted to help control the flow rate of clean oil or wastewater and better cope with processing conditions. Meanwhile, it eliminates the redundant steps of "rinsing and discharging wastewater from the receiving tank after collection" in existing technologies. This not only reduces water consumption and cleaning time costs, but also avoids secondary impurities that may be generated during rinsing. In addition, the independent wastewater tank can be directly connected to the subsequent wastewater treatment system without separating wastewater from the receiving tank, which improves the efficiency of oil collection and the convenience of wastewater treatment, reduces human error, and further ensures the stability and continuity of the production process.

[0019] Please refer to the appendix carefully. Figure 1-5 A filter press liquid receiving device includes a plate and frame body 1 and a guide-type liquid receiving mechanism 2 below the plate and frame body 1. The guide-type liquid receiving mechanism 2 includes a guide plate 21, a liquid receiving tank 22, a wastewater tank 23, and a plurality of lead screws 24. The guide plate 21 is located below the filter plate of the plate and frame body 1. The liquid receiving tank 22 and the wastewater tank 23 are located on both sides below the guide plate 21. The lower side of the guide plate 21 is connected to a guide frame 25 by bolts. The plurality of lead screws 24 are arranged linearly at equal intervals. Each lead screw 24 is provided with a nut seat 241. Each nut seat 241 is provided with a detachable guide block 242. The guide block 242 is slidably connected to the guide frame 25.

[0020] Through the above structure, the coordinated design of the switchable guide plate 21, independent liquid receiving tank 22, and wastewater tank 23 is realized, achieving the goal of immediate physical isolation between clean oil and wastewater. This avoids the risk of wastewater residue remaining on the inner wall of the liquid receiving tank 22 and causing cross-contamination of the clean oil in the subsequent process, which is especially suitable for the hygiene precision requirements of food-grade oil processing such as rice bran oil. At the same time, it eliminates the redundant steps of "rinsing and discharging the liquid receiving tank 22 after wastewater collection" in the prior art, which not only reduces water consumption and cleaning time costs, but also avoids secondary impurities that may be generated during the rinsing process and reduces human operation errors.

[0021] The specific operation is as follows: When the plate and frame machine body 1 collects clean oil by squeezing the filter plate, the motor 27 drives the lead screw 24 to rotate. At the same time, with the cooperation of the pulley 28 and the belt, multiple lead screws 24 rotate synchronously. Subsequently, the nut seat 241 on the lead screw 24 drives the guide block 242 to move towards the wastewater tank 23. One inclined surface on the guide block 242 contacts the slide rail 253 of the guide frame 25 and pushes and squeezes it. Subsequently, the guide plate 21 deflects counterclockwise with the support shaft 26 as the fulcrum, so that the upper side of the guide plate 21 forms an inclined surface facing the liquid receiving tank 22, which can guide the clean oil into the liquid receiving tank 22 for collection. When it is necessary to clean the filter plate, the motor 27 drives the lead screw 24 to rotate in the opposite direction, so that the nut seat 241 drives the guide block 242 to move towards the liquid receiving tank 22 and pushes the guide frame 25 on the other side, so that the guide plate 21 deflects clockwise, which can guide the wastewater into the wastewater tank 23 for collection.

[0022] Please refer to the appendix carefully. Figure 3 and attached Figure 4 Each lead screw 24 is equipped with a pulley 28, and adjacent pulleys 28 on different lead screws 24 are connected by a belt. Through the cooperation between the pulleys 28 and the belt, multiple lead screws 24 can rotate synchronously. Each lead screw 24 has a support frame 243 sleeved at both ends of its outer edge. The circular hole on the support frame 243 is rotatably connected to the lead screw 24. The support frame 243 provides a stable rotation environment for the lead screw 24. The guide liquid receiving mechanism 2 also includes a motor 27. The output end of the motor 27 is connected to one end of one of the lead screws 24. The motor 27 provides driving force for the rotation of the lead screw 24.

[0023] Please refer to the appendix carefully. Figure 3 and attached Figure 5 The guide plate 21 includes a transition section 211, a guide section 212, and a limiting section 213. The guide section 212 is located on both sides of the transition section 211, and the limiting section 213 is located on both sides of the flow-guiding surface formed by the guide section 212 and the limiting section 213. The guide plate 21 changes the flow direction of the liquid, allowing it to be directed into the receiving tank 22 or the wastewater tank 23 depending on the type of liquid. A support shaft 26 is installed in the circular hole on the guide plate 21. The support shaft 26 is attached to the bracket of the plate-frame body 1. Limit sleeves 261 are provided at both ends of the support shaft 26. The sleeve 261 and the bracket of the plate frame body 1 are connected by bolts. Through the cooperation between the support shaft 26 and the limiting sleeve 261, the guide plate 21 can be stably deflected on the bracket of the plate frame body 1. The guide frames 25 are linearly distributed at equal intervals on both sides of the lower surface of the guide plate 21. Each guide frame 25 includes a mounting part 251, a connecting part 252 and a slide rail part 253. The slide rail part 253 and the inclined surface on the corresponding guide block 242 are slidably connected. The cooperation between the inclined surfaces pushes the guide plate 21 to deflect within a certain degree to achieve the purpose of guidance.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
