Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a filtration device for tofu production. Background Technology

[0002] A filter screen, or simply filter mesh, is made of metal wire mesh with different mesh sizes. Its function is to filter molten material flow and increase flow resistance, thereby removing mechanical impurities and improving mixing or plasticizing effects. It possesses properties such as acid resistance, alkali resistance, temperature resistance, and wear resistance. It is mainly used in mining, petroleum, chemical, food, pharmaceutical, and machinery manufacturing industries. Filter screens are divided into textile fiber filter screens and metal filter screens. The machine that installs the filter screen is called a filter. Existing filtration equipment used in tofu production suffers from problems such as easy corrosion, rust or wear, poor air permeability, uneven precision, poor regeneration performance, slow regeneration speed, complex installation, low efficiency, and short service life.

[0003] Publication number CN207384956U discloses a filtration device for tofu production, including a filter funnel, a purification screen, a filter, a working indicator light, a production filtration device, a compressor, an air pump, casters, an impurity tank, a motor, a water pump, and a dust discharge port. The filter funnel is located on top of the purification screen, and the filter tube is located at the bottom of the purification screen. This invention, through the arrangement of the purification screen, filter, working indicator light, compressor, and impurity tank, improves acid and alkali resistance, impact resistance, dust removal effect, corrosion resistance, air permeability, uniform precision, strong regeneration performance, fast regeneration speed, simple installation, improved purification efficiency, and long service life. It also improves anti-slip performance, facilitates impurity storage, enhances purification effect, and is easy to move, thus improving work efficiency and achieving optimal performance. However, it does not solve the problem of easily separating and collecting soy milk and soy milk residue. Therefore, we propose a filtration device for tofu production. Utility Model Content

[0004] The purpose of this invention is to provide a filtration device for tofu production.

[0005] To achieve the goal of facilitating the separation and collection of soybean milk and soybean milk residue as described in the above technical solution, this utility model provides a filtration device for tofu production, including a fixed base and a filtration assembly. The filtration assembly is fixedly connected to the top of the fixed base. The filtration assembly includes a square protective shell, an outer protective cylinder is fixedly connected inside the square protective shell, and an inner protective cylinder is fixedly connected inside the outer protective cylinder. The outer and inner protective cylinders have a ceramic layer in the middle. The surfaces of the outer and inner protective cylinders have two sets of strip-shaped holes. Two sets of support rods are fixedly connected to one side of the inner protective cylinder parallel to the two strip-shaped holes. Two mounting frames are slidably connected to the surfaces of the two sets of support rods. Four spring dampers are fixedly connected to the four corners of the upper surface of the inner wall of the two mounting frames. Four connecting plates are fixedly connected to the lower surface of the four spring dampers. The lower surface of the four connecting plates has threaded holes. Two filter screens are fixedly connected to the lower surface of the four connecting plates by a set of fixing bolts.

[0006] Among them, the two strip-shaped holes are staggered and parallel to each other, and the two ends of the two sets of support rods are respectively fixed to the cylinder wall surface of the two sets of strip-shaped holes that are parallel to the two sets of strip-shaped holes. A guide groove is fixedly connected to one side of the strip-shaped hole located at the bottom of the outer side of the outer protective cylinder, and the guide groove encounters the side that penetrates the square protective shell.

[0007] By staggering and aligning the two strip-shaped holes, the soybean residue can flow more orderly along the holes under the influence of gravity and vibration, preventing blockages. Two sets of support rods are fixed at both ends to the corresponding inner protective cylinder wall surface, providing stable support and precise guidance for the installation frame. A guide groove is connected to one side of the strip-shaped hole on the outer side of the bottom outer protective cylinder and extends through one side of the square protective shell, effectively guiding the filtered soybean residue to the external collection device and ensuring a smooth collection path.

[0008] The guide groove is fixedly connected to a discharge pipe at the end away from the outer protective cylinder, and the discharge pipe is connected to a slag storage box at the end away from the square protective shell. The mesh size of the filter screen at the top is larger than that of the filter screen at the bottom.

[0009] By connecting a discharge pipe to the end of the guide trough furthest from the outer protective cylinder, and connecting the discharge pipe to the slag storage box, the soybean residue transported from the guide trough is smoothly discharged into the slag storage box, completing the final collection and storage of the soybean residue. The top filter screen has a larger mesh size than the bottom filter screen, achieving the purpose of first using the large-mesh top filter screen for preliminary filtration to intercept larger particle impurities, and then using the small-mesh bottom filter screen for further fine filtration, thereby improving the accuracy and quality of soybean milk filtration.

[0010] The inner protective cylinder at the bottom of the support rod has two H-shaped mounting brackets fixedly connected to its wall surface, and a protective cover is fixedly connected to the middle of the upper surface of the two H-shaped mounting brackets.

[0011] By fixing two H-shaped mounting brackets to the inner wall of the protective cylinder at the bottom of the support rod, and connecting a protective cover to the middle of the upper surface of the H-shaped mounting brackets, protection is provided for internal components such as the vibration motor, preventing materials such as soy milk from splashing in and damaging the equipment. At the same time, it can also reduce the outward transmission of noise generated by vibration to a certain extent.

[0012] The protective cover has two small vibration motors fixedly connected to its inner upper surface, and the output ends of the two small vibration motors are rotatably connected to two vibration eccentric blocks.

[0013] By fixing two small vibration motors on the upper surface inside the protective cover and connecting the motor output end to a vibration eccentric block, when the motor runs, the vibration eccentric block generates eccentric motion, thereby giving the filter screen and spring damper a reciprocating vibration force, so that the filter screen can more effectively promote the passage of soy milk during the filtration process and improve the filtration efficiency.

[0014] The square protective shell has two protective doors movably connected to the side away from the discharge pipe, a protective cover movably connected to the top of the square protective shell, a feeding funnel movably connected to the top of the outer protective cylinder inside the square protective shell, and two spiral tubes fixedly connected to the lower surface of the feeding funnel.

[0015] Two movable protective doors are installed on the side of the square protective shell away from the discharge pipe, facilitating the installation and maintenance of the internal filter components. A movable protective cover at the top prevents debris from falling into the equipment and can be opened for easy feeding. A movable feeding funnel is installed at the top of the outer protective cylinder, with two spiral tubes connected to its lower surface. This allows the poured soybean milk mixture to be evenly transported to the filter screen below, ensuring uniform feeding.

[0016] The square protective shell has a fixed support base at its bottom, the slag storage box is installed on top of the support base, the bottom of the inner protective cylinder is connected to an output pipe, and the end of the output pipe away from the inner protective cylinder passes through the surface of the support base. A controller is fixedly connected to the surface of the fixed base at one end of the output pipe.

[0017] A stable support base is provided for the entire device by fixing it to the bottom of the square protective shell. The residue storage box is installed on top of the support base for easy and stable collection of soybean residue. The bottom of the inner protective cylinder connects to the output pipe, which extends through the surface of the support base, allowing the filtered soybean milk to be smoothly discharged from the device. A controller is installed at one end of the output pipe on the fixed base surface to centrally control various components of the device, such as the vibrating motor and the spiral tube, making the equipment operation more intelligent and automated, and meeting different filtration needs.

[0018] Compared with the prior art, this utility model provides a filtration device for tofu production, which has the following beneficial effects.

[0019] 1. This utility model discloses a filtration device for tofu production. Soy milk and other ingredients are fed into the device through a feeding funnel. A rotating spiral tube beneath the funnel evenly distributes the material to upper and lower filter screens. The upper filter screen has a larger mesh size, initially intercepting larger particles of impurities. The lower filter screen has a smaller mesh size, further refining the soy milk and separating it from the soy residue.

[0020] The soybean residue intercepted by the filter slides down through the staggered parallel strip-shaped holes on the surfaces of the outer and inner protective cylinders. This staggered parallel design guides the flow of the soybean residue, allowing it to move more orderly and preventing blockages. Under the influence of gravity and vibration, the soybean residue converges towards the guide channel on the outer side of the bottom outer protective cylinder, near the strip-shaped holes. The guide channel directs the soybean residue to the discharge pipe, smoothly conveying it to the residue storage box, thus completing the collection process.

[0021] After being filtered through two layers of filters, the soy milk flows out through the filter and exits through the output pipe connected to the bottom of the inner protective cylinder. The output pipe passes through the surface of the support base, guiding the filtered soy milk to a storage container placed below the output pipe, thus collecting the soy milk.

[0022] In summary, the separation of soy milk and soy pulp is achieved through two layers of filters with different mesh sizes, the collection of soy pulp is achieved through strip-shaped holes, guide grooves and discharge pipes, and the collection of soy milk is achieved through the output pipe. Ultimately, the device facilitates the separation and collection of soy milk and soy pulp.

[0023] 2. This utility model discloses a filtration device for tofu production, featuring a ceramic layer and inner and outer protective cylinders. A ceramic layer is positioned between the outer and inner protective cylinders. The high strength, high temperature resistance, and corrosion resistance of the ceramic layer effectively protect the inner and outer protective cylinders. During operation, the ceramic layer buffers and resists external factors such as impacts from the soy milk mixture and potential temperature changes, enhancing the structural stability of the inner and outer protective cylinders and extending the equipment's service life. Simultaneously, the parallel, staggered perforations on the surfaces of the inner and outer protective cylinders allow the soybean residue to flow more orderly along the perforations into the guide channel under gravity and vibration, preventing blockages and ensuring a smooth discharge path for the soybean residue.

[0024] Controller function: The controller, which is fixed on the surface of the base and located at one end of the output tube, establishes an electrical connection with various components of the equipment, such as the vibration motor and the spiral tube, to achieve precise control of each operating aspect of the equipment.

[0025] In summary, by rationally designing the ceramic layer and inner and outer protective cylinders to enhance the structural stability of the equipment, and by utilizing the controller to precisely regulate each component, the device achieves the goal of being easy to control and improving stability, ensuring stable and efficient operation of the equipment during the tofu production filtration process.

[0032] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0033] refer to Figures 1 to 4A filtration device for tofu production includes a fixed base 1 and a filter assembly 2. The filter assembly 2 is fixedly connected to the top of the fixed base 1. The filter assembly 2 includes a square protective shell 201, an outer protective cylinder 202 fixedly connected inside the square protective shell 201, and an inner protective cylinder 203 fixedly connected inside the outer protective cylinder 202. A ceramic layer 204 is located in the middle of the outer protective cylinder 202 and the inner protective cylinder 203. Two sets of strip-shaped holes 205 are formed on the surface of the outer protective cylinder 202 and the inner protective cylinder 203. The inner protective cylinder 203 is flat. Two sets of support rods 206 are fixedly connected to one side of the two strip-shaped holes 205. Two mounting frames 207 are slidably connected to the surfaces of the two sets of support rods 206. Four spring dampers 208 are fixedly connected to the four corners of the upper surface of the inner wall of the two mounting frames 207. Four connecting plates 209 are fixedly connected to the lower surface of the four spring dampers 208. Threaded holes are opened on the lower surface of the four connecting plates 209. Two filter screens 211 are fixedly connected to the lower surface of the four connecting plates 209 by a set of fixing bolts 210.

[0034] Two strip-shaped holes 205 are staggered and parallel to each other. The two ends of the two sets of support rods 206 are respectively fixed to the cylinder wall surface of the inner protective cylinder 203, which is parallel to the two sets of strip-shaped holes 205. A guide groove 212 is fixedly connected to one side of the strip-shaped hole 205 at the bottom of the outer side of the outer protective cylinder 202, and the guide groove 212 encounters the side that penetrates the square protective shell 201.

[0035] The end of the guide channel 212 away from the outer protective cylinder 202 is fixedly connected to the discharge pipe 213, and the end of the discharge pipe 213 away from the square protective shell 201 is connected to the slag storage box 214. The mesh size of the filter screen 211 at the top is larger than that of the filter screen 211 at the bottom.

[0036] Two H-shaped mounting brackets 215 are fixedly connected to the inner protective cylinder 203 at the bottom of the support rod 206, and a protective cover 216 is fixedly connected to the middle of the upper surface of the two H-shaped mounting brackets 215.

[0037] Two small vibration motors 217 are fixedly connected to the upper surface inside the protective cover 216, and two vibration eccentric blocks 218 are rotatably connected to the output ends of the two small vibration motors 217.

[0038] Two protective doors 3 are movably connected to the side of the square protective shell 201 away from the discharge pipe 213. A protective cover 4 is movably connected to the top of the square protective shell 201. A feeding funnel 5 is movably connected to the top of the outer protective cylinder 202 inside the square protective shell 201. Two spiral tubes 6 are fixedly connected to the lower surface of the feeding funnel 5.

[0039] A support base 7 is fixedly connected to the bottom of the square protective shell 201. The slag storage box 214 is installed on the top of the support base 7. An output pipe 8 is connected to the bottom of the inner protective cylinder 203. The end of the output pipe 8 away from the inner protective cylinder 203 passes through the surface of the support base 7. A controller 9 is fixedly connected to the surface of the fixed base 1 at the end of the output pipe 8.

[0040] In this embodiment, the soy milk and soy residue are separated: the soy milk mixture enters the equipment through the feeding funnel 5, and the spiral tube 6 under the feeding funnel 5 rotates to evenly convey the material to the upper and lower filter screens 211. The upper filter screen 211 has a larger mesh size, which initially intercepts larger particles of impurities. The lower filter screen 211 has a smaller mesh size, which further refines the soy milk, thereby achieving the separation of soy milk and soy residue on the filter screen 211.

[0041] Soybean dregs collection: Soybean dregs intercepted by filter screen 211 slide down along the staggered parallel strip-shaped holes 205 on the surfaces of the outer protective cylinder 202 and inner protective cylinder 203. This staggered parallel design guides the flow direction of the soybean dregs, allowing them to move more orderly and preventing blockages. Under the action of gravity and vibration, the soybean dregs converge towards the guide groove 212 on one side of the strip-shaped holes 205 on the outer side of the bottom outer protective cylinder 202. The guide groove 212 guides the soybean dregs to the discharge pipe 213, thus smoothly conveying the soybean dregs to the dregs storage box 214, completing the soybean dregs collection.

[0042] Soy milk collection: After being filtered through two layers of filter screens 211, the soy milk flows out through the filter screens 211 and exits from the output pipe 8 connected to the bottom of the inner protective cylinder 203. The output pipe 8 passes through a controller 9 fixed to the surface of the fixed base 1 and located at one end of the output pipe 8. Through electrical connection with various components of the equipment, such as the vibration motor and the spiral tube 6, precise control of each operating stage of the equipment is achieved. By guiding the filtered soy milk to the storage container placed below the output pipe 8, the soy milk is collected.

[0043] Working principle: The user first places the feeding funnel 5 on top of the outer protective cylinder 202. This placement method provides an inlet for the soybean milk mixture to enter the equipment, thus determining the starting point for material feeding.

[0044] Open the protective door 3 of the square protective shell 201. Using the two sets of strip-shaped holes 205 on the surfaces of the outer protective cylinder 202 and the inner protective cylinder 203, slide the two mounting frames 207 along the surfaces of the two sets of support rods 206 fixed parallel to one side of the strip-shaped holes 205 on the inner protective cylinder 203 until the mounting frames 207 reach the top of the support rods 206. This operation, through the support and guidance of the support rods 206 on the mounting frames 207, achieves convenient installation and precise positioning of the filter assembly 2.

[0045] The container for storing soy milk is placed below the output end of the output tube 8. This placement prepares the container for receiving the filtered soy milk and ensures that the filtered soy milk can be properly collected.

[0046] After the installation structure is completed, the user opens the protective cover 4 on the top of the square protective shell 201 and pours the soy milk mixture into the feeding funnel 5. At this time, the two spiral tubes 6 fixedly connected to the lower surface of the feeding funnel 5 begin to function. Through the rotation of the spiral tubes 6, the poured soy milk mixture is evenly transported to the filter screen 211 below, so that the material is evenly distributed in the filtration area, laying the foundation for subsequent efficient filtration.

[0047] When the mixture enters the top of the two filter screens 211, which are connected to the four connecting plates 209 by four spring dampers 208 at the four corners of the upper surface of the inner wall of the mounting frame 207 and fixed by the fixing bolt group 210, the two small vibration motors 217 installed on the upper surface inside the protective cover 216 are activated. The output ends of the small vibration motors 217 are rotatably connected to two vibration eccentric blocks 218, which generate eccentric motion as the motors run. This eccentric motion provides a reciprocating vibration force to the filter screens 211 and the spring dampers 208 connected to them. During this process, the spring dampers 208 provide elastic support for the filter screens 211 on the one hand, and buffer and stabilize the vibration of the filter screens 211 on the other hand, so that the soy milk can pass through the filter screens 211 more smoothly, while the soy pulp is trapped on the filter screens 211, thus achieving the separation of soy milk and soy pulp.

[0048] The soybean residue trapped on the filter screen 211 moves along the parallel, staggered strip-shaped holes 205 on the surfaces of the outer protective cylinder 202 and the inner protective cylinder 203. Under the combined action of gravity and vibration, it moves towards the guide groove 212 connected to the outer side of the outer protective cylinder 202's strip-shaped holes 205. The guide groove 212 guides the soybean residue to the discharge pipe 213, and finally, the soybean residue enters the residue storage box 214 located at the top of the support base 7 through the discharge pipe 213. Through this series of guiding and conveying structures, the collection of soybean residue is completed.

[0049] The ceramic layer 204, positioned between the outer protective cylinder 202 and the inner protective cylinder 203, protects both cylinders 202 through its inherent properties, thereby enhancing the overall stability and durability of the equipment. The entire operation of the equipment, including the start and stop of the vibrating motor and the conveying speed of the spiral tube 6, is controlled by a controller 9 fixed to the surface of the base 1 and located at one end of the output pipe 8. This precise control of each component by the controller 9 ensures close coordination and orderly operation of all processes, achieving efficient filtration of soy milk during tofu production.

[0050] The above-disclosed filtration equipment for tofu production or a variety of preferred embodiments are merely examples of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
