DETAILED DESCRIPTION

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figures 1 to 7 As shown, a sterilization device for milk microfiltration includes a base plate 1 and microfiltration tanks 3. Several microfiltration tanks 3 are arranged, and each microfiltration tank 3 is vertically connected above the base plate 1. The top of each microfiltration tank 3 is connected to an interleaved hydraulic actuation assembly. The upper end of the tank wall of each microfiltration tank 3 is connected to a milk raw material conveying pipe 2. Multiple microfiltration tanks 3 can be combined and arranged through the base plate 1, and the milk raw material to be microfiltered can be conveyed into the microfiltration tank 3 through the milk raw material conveying pipe 2. The interleaved hydraulic actuation assembly can make two adjacent microfiltration tanks 3 perform different sterilization actions. Therefore, multiple microfiltration tanks 3 can be used separately for milk microfiltration sterilization, and uninterrupted milk microfiltration sterilization operation can be achieved.

[0030] The bottom of the microfiltration tank 3 is connected to a sterilized milk delivery pipe 31 and a sludge discharge pipe 32. The connection position of the sterilized milk delivery pipe 31 is higher than the connection position of the sludge discharge pipe 32. The microfiltration tank 3 contains a microfiltration membrane 36 and a supporting mesh plate 38. The microfiltration membrane 36 is fixedly connected to the upper surface of the supporting mesh plate 38. The supporting mesh plate 38 is connected to the drive end of an interlaced hydraulic push assembly. When the interlaced hydraulic push assembly moves the supporting mesh plate 38 upwards, it can compress the milk material inside the microfiltration tank 3. Under pressure, the milk material is filtered and sterilized by the microfiltration membrane 36. The sterilized milk drips to the bottom of the microfiltration tank 3 and can be discharged through the sterilized milk delivery pipe 31. Because the connection position of the sterilized milk delivery pipe 31 is higher than the sludge discharge pipe 32, the microfiltration tank 3 contains a microfiltration membrane 36 and a supporting mesh plate 38. Because of the connection position of the sludge conduit 32, some sterilized milk cannot be discharged through the sterilized milk delivery pipe 31. When the interlaced hydraulic push assembly drives the support mesh plate 38 to move downward, this part of the milk can form a backwash on the microfiltration membrane 36, that is, it can flush up the bacteria and impurities adhering to the microfiltration membrane 36 and discharge them through the sludge discharge conduit 32. This ensures that the microfiltration tank 3 can backwash the microfiltration membrane after each filtration, avoiding affecting subsequent microfiltration operations. During the downward movement of the support mesh plate 38, milk raw materials can be drawn into the microfiltration tank 3 for the next microfiltration process. Microfiltration sterilization through the microfiltration membrane can ensure that the nutritional components of the milk are not damaged and achieve the ideal sterilization effect, and can also achieve the goal of milk protein concentration.

[0031] The staggered hydraulic actuation assembly includes hydraulic outer rods 4, fluid guide pipes 41, pistons 44, and push rods 45. Both pistons 44 and push rods 45 are movably mounted within the hydraulic outer rods 4. The push rod 45 is connected to the lower end of the piston 44, and its bottom end is inserted into the microfiltration tank 3. The bottom end of the push rod 45 is coaxially and fixedly connected to the support mesh plate 38. Fluid guide pipes 41 connect the hydraulic outer rods 4, with adjacent guide pipes 41 staggered vertically. When hydraulic oil enters from one side of the hydraulic outer rod 4... The piston 44 inside the hydraulic outer rod 4 can be moved, and at the same time, the hydraulic oil inside the hydraulic outer rod 4 can be transported to another hydraulic outer rod 4 through the guide pipe 41, so that the piston 44 inside the other hydraulic outer rod 4 can move in the opposite direction. That is, it can drive the support mesh plate 38 inside the microfiltration tank 3 to move in different directions, so that one microfiltration tank 3 can perform microfiltration treatment, and the other microfiltration tank 3 can extract milk raw materials and backwash the microfiltration membrane 36.

[0032] Example 2

[0033] Improvements based on Example 1:

[0034] like Figures 1 to 7 As shown, a fixed support plate 11 is arranged parallel above the base plate 1. Supporting vertical rods 12 are fixedly connected to the four corners of the fixed support plate 11. The bottom end of the supporting vertical rods 12 is fixedly connected to the upper surface of the base plate 1. Several limiting installation holes 13 are arranged in parallel on the fixed support plate 11. The body of the microfiltration tank 3 is fixedly placed in the limiting installation holes 13 so that the microfiltration tanks 3 can be fixedly connected in parallel through the multiple limiting installation holes 13. It can also ensure that the microfiltration tanks 3 are fixedly placed vertically above the base plate 1. That is, when the microfiltration membrane 36 moves upward to apply pressure to the milk raw material in the microfiltration tank 3, the weight of the milk raw material can cooperate to apply pressure, thereby improving the filtration and sterilization efficiency of the milk raw material.

[0035] Furthermore, the milk raw material conveying pipe 2 is connected to several branch pipes 21, each corresponding to a microfiltration tank 3. The other end of each branch pipe 21 is connected to the upper end of the pipe wall of the microfiltration tank 3. A branch pipe check valve 22 is installed on the branch pipe 21 to convey milk raw materials into the microfiltration tank 3. Through the action of the branch pipe check valve 22, when the microfiltration membrane 36 moves upward to pressurize the milk raw materials in the microfiltration tank 3, the milk raw materials in the tank will not flow back into the milk raw material conveying pipe 2. During the downward movement of the support mesh plate 38, the branch pipe 21 can automatically inject milk raw materials into the microfiltration tank 3.

[0036] Further, the milk conveying pipe 31 is provided with a conveying electromagnetic valve 33, and the microfiltration tank 3 is provided with a liquid collecting output pipe 5, the pipe body of the liquid collecting output pipe 5 is communicated with the milk conveying pipes 31, so that the opening and closing of the milk conveying pipes 31 can be controlled by the conveying electromagnetic valve 33, and the milk after microfiltration and sterilization can be conveyed to the liquid collecting output pipe 5 through the milk conveying pipes 31, and then the milk after sterilization can be collected through the liquid collecting output pipe 5.

[0037] Further, the slag discharge pipe 32 is provided with a slag discharge electromagnetic valve 34, and the microfiltration tank 3 is provided with a slag collecting output pipe 6, the pipe body of the slag collecting output pipe 6 is communicated with the slag discharge pipes 32, so that the opening and closing of the slag discharge pipes 32 can be controlled by the slag discharge electromagnetic valve 34, and then the slag discharge pipes 32 can be closed during the microfiltration and sterilization process, so as to prevent the milk after microfiltration and sterilization from being discharged through the slag discharge pipes 32, and when the backwashing of the microfiltration membrane 36 is performed, the slag discharge pipes 32 can be in the open state through the slag discharge electromagnetic valve 34, so that the milk with bacteria and impurities after backwashing can be discharged.

[0038] Further, the rod body of the push rod 45 is further fixedly connected with a liquid blocking plate 35, the liquid blocking plate 35 is located above the support mesh plate 38, and a plurality of pressure valves 37 are installed on the plate body of the liquid blocking plate 35, when the push rod 45 pushes the support mesh plate 38 to move downward, the liquid blocking plate 35 also moves downward, so as to pump the milk raw material into the microfiltration tank 3, at this time, the milk raw material is blocked by the liquid blocking plate 35, so that when the part of the milk remaining at the bottom of the tank backwashes the microfiltration membrane 36, the milk with bacteria and impurities after backwashing will not mix with the milk raw material above the liquid blocking plate 35, that is, the slag discharge pipes 32 can only discharge the milk with bacteria and impurities after backwashing, when the push rod 45 pushes the support mesh plate 38 to move upward, the liquid blocking plate 35 also moves upward, at this time, the pressure valves 37 can be opened under the pressure of the milk raw material, so as to flow the milk raw material to the microfiltration membrane 36, and then the microfiltration membrane 36 can microfiltrate the milk raw material under pressure with the continuous flow of the milk raw material.

[0039] Further, the liquid blocking plate 35 and the support mesh plate 38 are provided with a sealing rubber ring 39, and the sealing rubber ring 39 is tightly attached to the inner wall of the microfiltration tank 3, so that the gap between the liquid blocking plate 35 and the inner wall of the microfiltration tank 3 and the gap between the support mesh plate 38 and the inner wall of the microfiltration tank 3 can be sealed by the sealing rubber ring 39, so as to prevent the milk raw material from overflowing from the gaps.

[0040] Further, the upper end of the rod body of the hydraulic outer rod 4 on one side of the staggered hydraulic pushing assembly is connected with an upper end liquid pipe 42, and the lower end of the rod body of the hydraulic outer rod 4 on the other side of the staggered hydraulic pushing assembly is connected with a lower end liquid pipe 43, the upper end liquid pipe 42 and the lower end liquid pipe 43 are connected with the external hydraulic system, and the pushing rod 45 in the hydraulic outer rod 4 can be driven to move reversely by inputting hydraulic oil into the upper end liquid pipe 42 or the lower end liquid pipe 43, so as to facilitate the control and adjustment of the driving direction of the staggered hydraulic pushing assembly.

[0041] Working principle: the milk raw material to be micro-filtered is delivered into the micro-filter tank 3 through the milk raw material delivery pipe 2, and the staggered hydraulic pushing assembly can make the adjacent two micro-filter tanks 3 perform different sterilization actions, when the staggered hydraulic pushing assembly drives the supporting mesh plate 38 to move upward, the milk raw material in the micro-filter tank 3 can be extruded, and then the milk raw material can be filtered and sterilized by the micro-filter membrane 36 under the pressure, the sterilized milk liquid drops at the bottom of the tank body of the micro-filter tank 3, and can be guided out through the sterilized milk delivery pipe 31, since the connection position of the sterilized milk delivery pipe 31 is higher than that of the residue discharge pipe 32, part of the sterilized milk cannot be guided out through the sterilized milk delivery pipe 31, when the staggered hydraulic pushing assembly drives the supporting mesh plate 38 to move downward, the part of the milk can form a backflush to the micro-filter membrane 36, that is, the bacteria and sundries adhered to the micro-filter membrane 36 can be flushed up and discharged through the residue discharge pipe 32, that is, the micro-filter membrane can be backwashed once after each filtration of the micro-filter tank 3, so as to avoid affecting the subsequent micro-filtering operation, and during the moving process of the supporting mesh plate 38, the milk raw material can be sucked into the micro-filter tank 3, so as to facilitate the next micro-filtering operation.
