Description

Technical Field

[0001] This utility model relates to a soybean milk filtration device, and more particularly to a cooked soy milk sieve for soybean milk processing. Background Technology

[0002] In large-scale soy milk production, the process involves washing and impurity removal, soaking and softening, grinding, separation and filtration, homogenization and sterilization, and bottling. The separation and filtration process removes solid impurities (soy pulp) from the soy milk. Filter bags are a commonly used filtration method in this process. Compared to stainless steel mesh filters, filter bags offer similar filtration precision and extremely high durability, while having a very low purchase cost. Furthermore, due to the cylindrical shape of the filter bag, even if filter residue clogs the bottom mesh, soy milk can still be filtered by submerging the upper bag, meaning that the filtration capacity per pass is relatively substantial, resulting in a lower cleaning frequency. Even so, filter bags still need to be replaced periodically and thoroughly cleaned before reuse. However, replacing filter bags requires pausing the soy milk filtration process, thus impacting production efficiency. Summary of the Invention

[0003] This invention provides a cooked soy milk sieve for soybean milk processing, which solves the problem in the prior art that the filtration process needs to be paused when the filter material is replaced.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a cooked pulp screen for soybean milk processing, comprising: a pre-filter tee, two filter tube groups and a post-filter tee, the front ends of the two filter tube groups are connected to the pre-filter tee, and the rear ends of the two filter tube groups are connected to the post-filter tee; the filter tube group is composed of a ball valve, a horizontally fixed front end fixing pipe, a front end bend, a vertically arranged filter tube, a rear end bend and a horizontally fixed rear end fixing pipe connected in sequence, the front end fixing pipe and the rear end fixing pipe are provided with external threaded ports on the same side, one end of the front end bend and the rear end bend is movably fitted with a screw sleeve, and a limiting protrusion ring for limiting the screw sleeve from falling out is also provided, the limiting protrusion ring is provided with a sealing ring, the screw sleeve can be screwed into the external threaded port, and the port of the external threaded port is tightly fitted with the sealing ring, the filter tube is connected to the front end bend and the rear end bend in a flexible manner.

[0005] In use, unfiltered soy milk enters through the pre-filter tee, passes through one of the filter tube assemblies, and finally exits through the post-filter tee. The different filter tube assemblies are switched by controlling the opening and closing of two ball valves. When one filter tube assembly requires filter media replacement or cleaning, the other filter tube assembly can be switched to continue filtration, thus achieving the effect of filter media replacement without stopping the soy milk filtration process. Furthermore, for easy disassembly and installation of the filter tubes, this invention features a front bend and a rear bend at both ends of the filter tube assembly. This allows for the connection or separation of the two bends from the two fixed tubes by sliding them. After the assembly of the front bend, filter tube, and rear bend is removed as a whole, it can be disassembled individually until the filter tube is removed, allowing for the replacement and cleaning of the internal filter element. After the two bends are connected to the two fixed tubes, a sealed connection can be achieved by tightening the screw sleeve, making installation quick and convenient.

[0006] Furthermore, to achieve automated control, this utility model also includes a control system, which consists of a controller, a timer, a prompter, and electric actuators. The electric actuators are mounted on the two ball valves and control their opening and closing. By setting the timer's timing, the filter media replacement interval can be preset. When the timer is triggered, the controller sends commands to the prompter and the corresponding electric actuator. The prompter then uses one or more methods (sound, light, electricity, etc.) to remind the worker to perform the filter media replacement operation. The two electric actuators switch the state of the two ball valves.

[0007] Furthermore, coarse and fine filter bags are connected in series inside the filter tube. This allows for the diversion of filter cake, increasing the filtration volume and efficiency of a single filtration cycle.

[0008] Therefore, this utility model has the following characteristics compared with the prior art: 1. When a filter tube group needs filter media replacement and cleaning, it can be filtered by switching to another filter tube group, so as to achieve the effect of filter media replacement without stopping the soy milk filtration operation; 2. This utility model can achieve automated control through the control system, and accurately control the running time of each filter tube. Attached Figure Description

[0015] Example 1: See Figure 1 and Figure 2 A slurry screen for processing soybean milk includes: a pre-filter tee 10, two filter tube assemblies 20, and a post-filter tee 30. The front ends of the two filter tube assemblies are connected to the pre-filter tee, and the rear ends of the two filter tube assemblies are connected to the post-filter tee. The filter tube assembly consists of a ball valve 40, a horizontally fixed front-end fixed pipe 50, a front-end bent pipe 60, a vertically arranged filter tube 70, a rear-end bent pipe 80, and a horizontally fixed rear-end fixed pipe 90 connected in sequence. The front-end fixed pipe and the rear-end fixed pipe are provided with external threaded ports 100 on the same side. A swivel sleeve 110 is movably fitted at one end of the front-end bent pipe and the rear-end bent pipe. A limiting protrusion ring 120 is also provided to limit the sleeve from falling out. A sealing ring 130 is provided on the limiting protrusion ring. The sleeve can be screwed into the external threaded port, so that the port of the external threaded port is tightly fitted with the sealing ring. The pre-filter tee, the ball valve, and the front-end fixed pipe are fixedly connected by flanges, and the post-filter tee and the rear-end fixed pipe are also fixedly connected by flanges.

[0016] In this embodiment, unfiltered soy milk enters through the pre-filter tee, passes through one of the filter tube groups, and finally exits through the post-filter tee. The different filter tube groups are switched by controlling the opening and closing of two ball valves. When one filter tube group requires filter media replacement or cleaning, the other filter tube group can be switched to continue filtration, thus achieving the effect of filter media replacement without stopping the soy milk filtration process. Furthermore, for easy disassembly and installation of the filter tubes, this embodiment features a front bend and a rear bend at both ends of the filter tube group. This allows for the connection or separation of the two bends from the two fixed tubes by sliding them. After the assembly of the front bend, filter tube, and rear bend is removed as a whole, it can be disassembled individually until the filter tube is removed and its internal filter element is replaced and cleaned. After the two bends are connected to the two fixed tubes, a sealed connection can be achieved by tightening the screw sleeve, making installation quick and convenient.

[0017] See Figure 4 To achieve automated control, this embodiment also includes a control system, which consists of a controller, a timer, a prompter, and electric actuators. The electric actuators are mounted on the two ball valves and control their opening and closing. By setting the timer's timing, the interval for filter media replacement can be preset. When the timer is triggered, the controller sends commands to the prompter and the corresponding electric actuator. The prompter then uses one or more methods (sound, light, and electricity) to remind the worker to perform the filter media replacement operation. The two electric actuators switch the state of the two ball valves.

[0018] See Figure 1 The filter tube contains a coarse filter bag 21 and a fine filter bag 22 connected in series. This allows for the separation of filter cake, increasing the filtration volume and efficiency of a single filtration cycle.

[0019] See Figure 1 and Figure 3 The filter tube consists of two filter tubes 200 joined together. A coarse filter bag and a fine filter bag are respectively located inside the two filter tubes. The front and rear ends of the filter tubes are respectively equipped with an outer sleeve 210 and an inner tube 220. An inner tube is also provided at the end of the front bend for connecting to the filter tube, and an outer sleeve is provided at the end of the rear bend for connecting to the filter tube. A limiting shoulder 230 is formed at the root of the outer wall of any inner tube, allowing the inner tube to be inserted into the outer sleeve, with the end of the outer sleeve abutting against the limiting shoulder. This insertion-connection method between the inner tube and the outer sleeve not only facilitates assembly and disassembly but also reduces the risk of soy milk overflow.

[0020] See Figure 3 A limiting step 240 is provided on the inner wall of the filter tube near the outer sleeve. A bag fixing ring 250 is provided on the upper side of the limiting step. The coarse filter bag and the fine filter bag are fixed on the bag fixing ring.

[0021] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
