Description

Technical Field

[0001] The present invention relates to the technical field of filtering devices, in particular to a multiple filtering device for dairy product production. Background Art

[0002] The multi-filter for dairy production is a filtration device designed specifically for the dairy industry. It is used to efficiently and accurately remove tiny impurities from milk, ensuring the quality, safety, taste and shelf life of dairy products. It is an important link in the dairy production safety chain.

[0003] Dairy filters mainly filter milk through physical filtration and chemical filtration. Physical filtration uses filter plates to intercept larger impurities, while chemical filtration uses certain filter membrane materials to adsorb specific molecules or compounds in milk, such as certain proteins and specific bacteria. In physical filtration, excessive accumulation of impurities in the filter plates will make it difficult for the fluid to pass through, which will reduce the filtration efficiency of the milk. The accumulated impurities will also affect the quality of dairy products. Summary of the Invention

[0004] The present invention aims to solve the problem that dairy filters mainly filter milk through physical filtration and chemical filtration. Physical filtration uses a filter plate to intercept larger impurities, while chemical filtration uses certain filter membrane materials to adsorb specific molecules or compounds in milk, such as certain proteins and specific bacteria. In physical filtration, excessive accumulation of impurities in the filter pores of the filter plate will make it difficult for the fluid to pass through, which will reduce the filtration efficiency of the milk. The accumulated impurities will also affect the quality of dairy products. Therefore, a multi-filtration device for dairy production is proposed.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: a multiple filtration device for dairy product production, comprising a tank body, a sealing cover fixedly installed on the top of the tank body by bolts and a sealing ring, a feed pipe welded to the outer surface of the sealing cover, an air intake pipe welded to the top of the tank body, a pressure gauge is provided on the top of the air intake pipe, a filter plate is provided on the inner wall of the tank body, a filter membrane is fixedly installed on the bottom of the filter plate, a cleaning device is provided inside the filter membrane, the cleaning device cleans the filter holes of the filter plate by moving up and down a push plate with several push rods, and a discharge pipe is fixedly installed on the bottom of the tank body.

[0006] The effect achieved by the above components is: when the push rod moves upward, it will push the inner wall of the filter plate and make the impurities leave the inner wall holes of the filter plate, so as to facilitate the direct cleaning of the impurities, which is beneficial to prevent the impurities from accumulating in the filter holes and causing blockage of the filter holes, making it difficult for the fluid to pass through, thereby improving the filtration efficiency of milk and preventing the accumulation of impurities from affecting the quality of dairy products.

[0007] Preferably, the cleaning device includes a push plate, which is arranged inside the filter membrane, and a push rod is evenly fixedly installed on the top of the push plate. The size and shape of the outer surface of the push rod are adapted to the size and shape of the inner wall of the filter hole on the filter plate, and the push rod corresponds one-to-one to the filter hole of the filter plate. A round rod is fixedly installed in the middle of the top of the push plate, and the outer surface of the round rod is slidably installed on the inner wall of the filter plate, and an auxiliary plate is fixedly installed on one end of the round rod.

[0008] The effect achieved by the above components is: pulling the auxiliary plate upward, the auxiliary plate will drive the round rod to move upward, and the round rod will drive the push plate and the push rod to move upward. When the push rod moves upward, it will gradually enter the filter holes of the filter plate, and make the impurities in the filter holes separate from the filter holes and fall on the top of the filter plate, which makes it easier to clean the impurities directly, and helps prevent impurities from accumulating in the filter holes and causing blockage of the filter holes.

[0009] Preferably, a same spring is fixedly mounted on one side of the auxiliary plate and the filter plate, and bumps are symmetrically fixedly mounted on the top of the auxiliary plate.

[0010] The effect achieved by the above components is: by setting a spring, the auxiliary plate connected to the round rod can be connected to the filter plate; when the spring is not subjected to other external forces, the spring will stretch the push plate so that the push plate can be maintained in a position relatively close to the bottom of the filter plate; at the same time, when the sealing cover completely seals the tank body, the inner wall of the sealing cover will abut against the protrusion on the top of the auxiliary plate, and at this time there is still a certain distance between the push rod and the filter plate, and the protrusion can prevent the auxiliary plate from abutting against the sealing cover, which is beneficial to prevent the auxiliary plate from blocking the outlet of the air intake pipe and facilitates pressurization of the inner wall of the tank body through the air intake pipe.

[0011] Preferably, the vertical cross-section of the push plate is in a shape with high edges and a middle, and auxiliary filter holes are evenly opened in the middle of the top of the push plate.

[0012] The effect achieved by the above components is: by setting auxiliary filter holes, it is convenient to perform secondary filtration on the milk passing through the filter plate through the auxiliary filter holes, and it can block the small amount of impurities brought down by the push rod during the cleaning of the filter plate. At the same time, the edge of the push plate is high and the middle is low, which makes it easy to gather milk in the auxiliary filter holes in the middle of the push plate, thereby improving the filtration rate of the milk.

[0013] Preferably, a rubber ring is fixedly mounted on the outer surface of the push plate, and the outer surface of the rubber ring abuts against the inner wall of the filter membrane.

[0014] The effect achieved by the above components is: by setting the rubber ring, the rubber ring can assist in sealing between the push plate and the filter membrane, which is beneficial to prevent larger impurities from entering the interior of the filter membrane through the gap between the push plate and the filter membrane and affecting the filtration performance of the filter membrane.

[0015] Preferably, an auxiliary device is provided at the bottom of the push plate, and the auxiliary device includes a cloth bag, and the cloth bag is provided at the bottom of a plurality of auxiliary filter holes.

[0016] The effect achieved by the above components is: by setting up the cloth bag, the cloth bag can receive the milk flowing out through the auxiliary filter hole, and at the same time can block the larger fat particles in the milk, which is beneficial to reduce the filtration pressure of the filter membrane, thereby improving the filter membrane's filtration ability for milk.

[0017] Preferably, a rubber ring is fixedly installed at one end of the cloth bag, and four circular hole blocks are evenly fixedly installed on the outer surface of the rubber ring. A threaded pin is inserted into the inner wall of the circular hole block, and one end of the threaded pin is fixedly installed on the bottom of the push plate. A nut is threadedly connected to the outer surface of the threaded pin, and the threaded pin and nut are both made of stainless steel.

[0018] The effect achieved by the above components is: insert the threaded pin into the inner wall of the circular hole block, and then rotate the nut so that one side of the nut squeezes the circular hole plate, and then squeezes the rubber ring, so that the rubber ring assists in sealing between the cloth bag and the push plate, which helps prevent milk from overflowing through the connection between the cloth bag and the push plate without being filtered by the cloth bag. The threaded pin and nut made of food-grade stainless steel can work normally in a humid environment more easily, and will not easily rust and affect the quality of dairy products.

[0019] Preferably, four limiting rings are evenly and fixedly connected to the bottom of the push plate, one side of the limiting ring abuts against the outer surface of the rubber ring, and both ends of the limiting ring abut against one side of two adjacent circular hole blocks respectively.

[0020] The effect achieved by the above components is: by setting a limiting ring, the rubber ring and the bottom of the push plate can be further sealed, thereby improving the sealing performance between the rubber ring and the push plate, and at the same time, the rubber ring can be limited, which is beneficial to improving the stability of the connection between the cloth bag and the push plate.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are: 1. In the present invention, a push plate with several push rods is provided. When the push plate and the push rods move upward, the push rods push the impurities in the inner wall of the filter plate and make the impurities separate from the inner wall holes of the filter plate, thereby facilitating direct cleaning of the impurities. This helps prevent the impurities from accumulating in the filter holes and clogging the filter holes, which makes it difficult for the fluid to pass through. This helps improve the filtration efficiency of milk and prevents the accumulation of impurities from affecting the quality of dairy products.

[0022] When the filter bag is in a closed position, the filter bag is moved back to the filter bag, and the filter bag is then moved back to the filter bag, so that the filter bag can be cleaned directly.

[0023] 3. In the present invention, milk enters the tank through the feed pipe, and the filter plate will block larger impurities in the milk. The milk will fall onto the push plate after passing through the filter plate. The edge of the push plate is high and the middle is low, which makes it easy to gather the milk in the auxiliary filter holes in the middle of the push plate, so that the milk can be filtered through the auxiliary filter holes and enter the cloth bag. The cloth bag can also further clean the impurities left in the milk. After the milk is filtered into the filter membrane by the cloth bag, the filter membrane can absorb the deteriorated protein and specific bacteria in the milk, and finally the milk that has undergone multiple filtrations can be discharged through the discharge pipe.
