Description

Technical Field

[0001] This utility model belongs to the technical field of freeze-dried floc processing, and more specifically, it relates to a freeze-dried floc filtration device with a sterilization mechanism. Background Technology

[0002] Freeze-dried flocs are produced by first freezing a liquid solution containing active ingredients at low temperature, turning the water in the solution into solid ice, and then sublimating and drying it under high vacuum, directly converting the ice into water vapor and expelling it, ultimately obtaining a loose, porous, flocculent solid product.

[0003] Before freeze-dried flocs are frozen at low temperatures, they need to be filtered to remove impurities or lumps, as well as bacteria. Currently, filter membranes are commonly used in industrial production to filter freeze-dried floc solutions. However, the smaller the pore size of the filter membrane, the better the retention effect on bacteria and tiny impurities, but the greater the resistance to the solution flow, the significantly reduced filtration speed, and the lower the filtration efficiency to a certain extent. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a freeze-dried flocculent filtration device with a sterilization mechanism. This addresses the technical problem in existing technologies where smaller pore sizes of the filter membrane result in better retention of bacteria and minute impurities, but also greater resistance to solution flow, significantly reduced filtration speed, and consequently, lower filtration efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a freeze-dried flocculant filtration device with a sterilization mechanism, comprising a housing, a fan installed at one end of the housing, the fan being connected to the housing at one end, a feed inlet connected to one end of the housing, a mesh plate one, a mesh plate two, and a filter membrane arranged from top to bottom inside the housing, the mesh plate one, the mesh plate two, and the filter membrane being placed at an angle, a door hinged to one end of the housing, and a discharge valve installed at one end of the housing.

[0006] As a preferred technical solution of this utility model, multiple sets of openings are provided at one end and the other end of the box, and multiple sets of pipes are connected to one end and the other end of the box. The multiple sets of pipes are respectively connected to the corresponding openings. A motor is installed at one end of each set of pipes, and an auger is rotatably connected to each set of pipes. The output end of each set of motors is respectively connected to the corresponding auger, and a pipe group is connected to one end of each set of pipes.

[0007] As a preferred embodiment of this utility model, an observation window is embedded at one end of the housing.

[0008] As a preferred technical solution of this utility model, the box body is connected to multiple sets of plates, and one end of each set of plates is an inclined surface.

[0009] As a preferred technical solution of this utility model, the inside of the box is connected to one end and the other end of multiple sets of slide rails, and the mesh plate one, mesh plate two and filter membrane are all provided with slide grooves at one end and the other end, and the multiple sets of slide grooves are slidably connected to the corresponding slide rails respectively.

[0010] As a preferred embodiment of this utility model, a sealing gasket is adhered to the joint between the door and the box.

[0011] This invention provides a freeze-dried flocculant filtration device with a sterilization mechanism, which has the following beneficial effects:

[0012] 1. This novel design utilizes the coordination of a fan, inlet, and screen plate one. The freeze-dried flocculent solution is injected into the chamber through the inlet. The fan is activated, using the pressure difference to create traction, driving the solution to flow downwards at an accelerated rate. The solution first flows through the inclined screen plate one, where larger lumps and suspended particles slide down to the inlet due to interception. Subsequently, the solution undergoes secondary filtration through screen plate two, further trapping residual fine impurities and fibrous materials. This dual filtration reduces the load on subsequent precision filtration to some extent. The solution, after preliminary filtration, comes into full contact with the high-precision filter membrane at the bottom. The filter membrane accurately traps bacteria, microorganisms, and other tiny contaminants in the solution. At this point, the continuous suction provided by the fan allows the solution to quickly penetrate the membrane layer, shortening the filtration time and thus improving filtration efficiency.

[0013] 2. Through the cooperation of the auger, motor and tube assembly, screen plate one, screen plate two and filter membrane are placed at an angle. The impurities accumulated on screen plate one, screen plate two and filter membrane will slowly slide down the inclined surface to the inlet, and flow out into the tube body through the inclined inlet. The motor is started to drive the auger to rotate and transport the impurities. After the impurities move to a certain distance, they flow out from the tube assembly to complete the collection. Multiple inlets are connected to different tube bodies. The impurities of screen plate one, screen plate two and filter membrane flow out from different channels to complete the collection, which is convenient for subsequent processing.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a freeze-dried flocculant filtration device with a sterilization mechanism, comprising a housing 1, a fan 2 installed at one end of the housing 1 (the model of the fan 2 can be selected according to actual needs), and one end of the fan 2 connected to the housing 1. Activating the fan 2 extracts air from the housing 1, creating a negative pressure environment on one side of the housing 1 to accelerate the downward flow of the solution. One end of the housing 1 is connected to an inlet 3, through which the freeze-dried flocculant solution is injected into the housing 1. Inside the housing 1, from top to bottom, are arranged a first mesh plate 4, a second mesh plate 5, and a filter membrane 6. The first mesh plate 4 traps lumps and large particulate impurities in the freeze-dried flocculant solution, and the second mesh plate 5 performs secondary filtration of the freeze-dried flocculant solution after the initial filtration. Fine particles in the freeze-dried floc solution are trapped. The freeze-dried floc solution is then filtered twice by mesh plates 4 and 5, reducing the burden on the subsequent filter membrane 6. This method has a wide range of applications. The filter membrane 6 comes into contact with the freeze-dried floc solution after the second filtration, trapping bacteria. Mesh plates 4, 5, and 6 are all placed at an angle. After trapping impurities on the surface, the impurities slowly slide down the inclined plane to the inlet 7. The suction generated by the fan 2 creates a negative pressure inside the chamber 1, and the solution maintains a downward flow trend under the traction of the negative pressure. Therefore, the solution will not flow out backward from the inlet 7. Conversely, the impurities trapped on mesh plate 4, mesh plate 5, and filter membrane 6 will slide down along the inclined mesh plate and membrane surface to the inlet 7 under the action of their own gravity and the impact force of the solution flow. A door 12 is hinged to one end of the box body 1. Opening the door 12 can clean the inside of the box body 1 or remove mesh plate 4, mesh plate 5, and filter membrane 6 and replace them with different mesh sizes as needed. A discharge valve 15 is installed at one end of the box body 1. The filtered freeze-dried flocculent solution in the box body 1 can be discharged through the discharge valve 15. The suction force generated by the fan 2 accelerates the falling speed of the solution, which can speed up the solution filtration efficiency to a certain extent.

[0023] The housing 1 has multiple sets of inlets 7 at one end and the other end. Impurities that slide down fall into the pipe 8 through the inlets 7. Multiple sets of pipes 8 are connected to one end of the housing 1 and the other end. Each set of pipes 8 is connected to a corresponding inlet 7. Each set of pipes 8 is equipped with a motor 9 at one end. The model of the motor 9 can be selected according to the actual situation. Each set of pipes 8 is rotatably connected to an auger 10. The output end of each set of motors 9 is connected to a corresponding auger 10. When the motor 9 is started, it drives the auger 10 to transport impurities. Each set of pipes 8 is connected to a pipe group 11 at one end. Impurities move to the pipe group 11 and flow out through the pipe group 11 to be collected. The design of multiple sets of pipes 8 separates and collects impurities of different sizes, which facilitates subsequent processing to a certain extent.

[0024] One end of the box 1 is fitted with an observation window 14, through which the amount of solution inside the box 1 can be viewed.

[0025] The box 1 is connected to multiple sets of plates 16, each with an inclined surface at one end to guide the sliding impurities into the inlet 7.

[0026] The box 1 has multiple sets of slide rails 17 connected to one end and the other end. The mesh plate 4, the mesh plate 5 and the filter membrane 6 are all provided with slide grooves 18 at one end and the other end. The multiple sets of slide grooves 18 are slidably connected to the corresponding slide rails 17, providing guidance for the installation of the mesh plate 4, the mesh plate 5 and the filter membrane 6, and also serving as a limit after installation.

[0027] Among them, a sealing gasket 13 is attached to the joint between the door 12 and the box 1 to enhance the sealing of the box 1 and prevent the solution from overflowing from the gaps.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In use, the freeze-dried flocculent solution is injected into the chamber 1 through the inlet 3. The blower 2 is activated to create a negative pressure environment within the chamber 1, using the pressure difference to generate traction and accelerate the downward flow of the solution. The solution first flows through the inclined mesh plate 4. Larger lumps and suspended particles slide down the inclined surface to the inlet 7 due to the mesh's interception effect and are discharged through the pipe 8. The pre-filtered solution continues to pass through the second mesh plate 5, further trapping residual fine impurities and fibrous materials, reducing the load on subsequent precision filtration. The solution, after pre-filtration through the double-layer mesh plates, comes into full contact with the inclined filter membrane 6 at the bottom. The filter membrane 6, with its microporous structure, precisely traps bacteria, microorganisms, and other tiny contaminants in the solution. The blower 2 continuously provides suction, maintaining a negative pressure state within the chamber 1, allowing the solution to quickly penetrate the filter membrane 6 under the pressure difference, thus shortening the filtration time and improving filtration efficiency to a certain extent. The inclined design of mesh plate 4, mesh plate 5, and filter membrane 6 allows the trapped impurities to automatically slide down the inclined surface to the inlet 7 on the side wall of the housing 1, and then fall into the tube 8. The motor 9 is started to drive the auger 10 to rotate, and the impurities in the tube 8 move a certain distance before flowing out from the tube assembly 11, realizing the classified collection of impurities at different levels, which facilitates subsequent centralized processing to a certain extent.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
