Description

Technical Field

[0001] The utility model relates to the field of laboratory appliance manufacturing, in particular to a scroll-type continuous filter. Background Art

[0002] Polymer emulsions, such as common polyacrylate emulsions or polyurethane aqueous dispersion emulsions, are emulsions in which polymer particles are suspended in water using water as a solvent. Since no volatile organic solvents (VOCs) are required in the production process, it is a relatively environmentally friendly way to prepare polymers and has been widely used in many fields such as coatings, inks, adhesives, leather, papermaking, water treatment, and daily chemicals.

[0003] Polymer emulsion is a non-homogeneous liquid form, in which the polymer solid particles are suspended in water by the charge repulsion of surface anions and / or the steric hindrance of non-ions. This suspension is in a metastable state. Especially in the production and preparation process, due to shear force and high temperature, it is easy for ions to collide and merge, resulting in partial demulsification and agglomeration. As a result, a certain amount of agglomerates (usually called slag / slag content) will exist in the polymer emulsion after the preparation is completed, which needs to be filtered to achieve the effect of normal use.

[0004] Using filter bags (150-300 mesh) to filter under reduced pressure is a common way to filter polymer emulsions. However, during the filtration process, the residue in the emulsion often accumulates at the bottom of the filter bag, resulting in a slow filtration rate. Especially when the content of fine residue is high, the filter belt is prone to clogging. In this case, the filtration needs to be suspended to replace the filter bag, which makes it difficult to perform continuous filtration and greatly reduces the filtration efficiency.

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following structure, the description of the well-known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1 The scroll-type continuous filter shown includes a filter body 100, which is divided into a to-be-filtered chamber 101 and a filtering chamber 102 by a filtering membrane structure 200, wherein the to-be-filtered chamber 101 stores unfiltered materials;

[0027] The filtered material is stored in the filter chamber 102 .

[0028] A feed port 1011 is provided at the entrance of the filter chamber 101 , and a discharge port 1021 is provided at the outlet of the filter chamber 102 . The discharge port 1021 is connected to an external device (not shown) via a discharge pipeline 120 with a pressure reducing pump 121 .

[0029] One end of the filter membrane cloth 210 of the filter membrane structure 200 is arranged on the first reel 220, and the other end of the filter membrane cloth 210 of the filter membrane structure 200 is arranged on the second reel 230. The upper and lower ends of the filter membrane cloth 210 are provided with edge sealing to prevent the filter membrane cloth 210 from tearing when rotating.

[0030] A limiting frame 110 is arranged around the filter membrane cloth 210, and the filter membrane cloth 210 is pressed and slid in the limiting frame 110 to prevent the filter membrane cloth 210 from being washed away.

[0031] A plurality of flow rate detectors 300 are arranged in the filter chamber 102, and the flow rate of the filtrate passing through the filter chamber 102 is detected by the flow rate detectors 300. The flow rate detectors 300 may be probes or other forms of detectors. The flow rate detector is an instrument for measuring fluid velocity, which can provide important data on the velocity and direction of water flow.

[0032] The flow velocity detector 300 is connected to a reel controller (not shown in the figure), and when the flow velocity monitoring of the flow velocity detector 300 is abnormal, feedback is given to the reel controller (not shown in the figure);

[0033] The motor of the first reel 220 or the second reel 230 is controlled to rotate by a reel controller (not shown in the figure), thereby driving the movement of the filter membrane cloth 210 .

[0034] Because of the above structure, the working principle of the utility model is:

[0035] When the flow rate is lower than a certain value, the flow rate monitoring abnormality of the flow rate detector 300 is fed back to the reel controller (not shown in the figure);

[0036] The motor of the first reel 220 or the second reel 230 is controlled to rotate by a reel controller (not shown in the figure), thereby driving the movement of the filter membrane cloth 210 .

[0037] The part of the filter membrane cloth 210 that has been blocked is rolled out of the filter body 100, and a new filter membrane cloth 210 is rolled into the filter body 100. Thus, continuous filtration is achieved, and the filtered filtrate flows into the external device through the discharge pipeline 120 with the pressure reducing pump 121.

[0038] After a whole roll of the filter membrane cloth 210 is used up, it can be directly removed from the second reel 230 , and a new filter membrane cloth 210 can be installed between the first reel 220 and the second reel 230 .

[0039] The scroll-type continuous filter provided by the utility model avoids the problem of inability to perform continuous filtering due to filter screen blockage, can achieve effective continuous filtering, and greatly improves filtering efficiency.
