Description

Technical Field

[0001] The present application relates to the technical field of chemical reaction devices, and in particular to a filtering component and a reaction device. Background Art

[0002] In existing chemical reactions, multiple processes are often carried out in their own reaction devices according to the process. The entire system not only occupies a large space but is also cumbersome to operate. In order to solve the problem of multiple process separation, four-in-one or three-in-one reactor devices have appeared on the market. Such devices can realize filtration, washing, vacuuming, drying, extraction, crystallization and other processes in one device and carry them out in sequence.

[0003] The existing four-in-one or three-in-one reaction device structure, for example, the "three-in-one sealed reactor with independent discharge" disclosed in the invention patent with publication number CN116712962A and the "four-in-one drying reactor for insurance powder" structure disclosed in the utility model patent with publication number CN201626831U, both have the function of filtering process. In order to achieve solid-liquid separation, a filter plate is often arranged in the device. In the process of realizing solid-liquid separation, if the solid particles are fine and the permeability is poor, the filter holes of the filter plate will gradually be blocked and finally a layer of filter cake will be formed on the surface of the filter plate, which will seriously affect the normal progress of the filtering process and even lead to the inability to achieve filtering. Utility Model Content

[0004] In order to improve the filtering effect of solid-liquid separation, the first purpose of the present application is to provide a filtering component.

[0005] A filter assembly provided in this application adopts the following technical solution:

[0006] A filter assembly, comprising:

[0007] An outer base, wherein the outer base is a closed structure connected end to end;

[0008] At least one inner base is disposed in the closed area of ​​the outer base and is enclosed with the outer base to form at least one first filter area, wherein a first filter element is disposed in the first filter area; and

[0009] A support portion connected to the end surface of the inner base portion and extending upward from the end surface, wherein the support portion has a second filter area, and a second filter element is disposed in the second filter area;

[0010] Wherein, the support portion further has a filtrate cavity connected to the second filtration area, and the inner base portion is provided with a liquid guide port connected to the filtrate cavity.

[0011] By adopting the above technical scheme, when the solution is undergoing the filtering process, normal filtrate is filtered through the first filter element in the first filter zone, and when the solid particles in the solution are fine and the permeability is low, the solid particles on the surface of the first filter element gradually accumulate over time to form a filter cake, and in severe cases the first filter element will be blocked as a whole. At this time, the filtrate is mainly filtered through the second filter zone in the support portion. Since the support portion is extended upward from the end surface of the inner base portion, the thickness of the filter cake must be smaller than the height of the support portion. The filtrate can flow normally from the second filter zone and enter the filtrate cavity in the support portion, and finally be discharged from the liquid guide port of the inner base, thereby realizing the filtering operation as a whole. At the same time, under normal circumstances, the setting of multiple filter zones can also improve the filtrate efficiency and filtrate effect.

[0012] Preferably, the first filter area is arranged around the inner base.

[0013] By adopting the above technical solution, under the working condition of high solid permeability, the first filter zone can be utilized to the maximum extent possible to ensure the filtrate efficiency.

[0014] Preferably, at least one end of the inner base is connected to the inner side of the outer base and the first filtering area is formed between the two sides of the inner base and the outer base.

[0015] By adopting the above technical solution, under the working condition of poor solid permeability, the area of ​​the first filter zone is limited, so that the filtrate can mainly pass through the second filter zone, ensuring the normal progress of the filtration process.

[0016] Preferably, the support portion further comprises:

[0017] A third filtering area is provided at an end of the supporting portion;

[0018] Wherein, a third filter element is arranged in the third filter area, and there is a vertical height difference between the third filter area and the first filter area.

[0019] By adopting the above technical solution, the setting of the third filter zone can better ensure the normal progress of the filtration process. When flow limitation or blockage occurs in the first and second filter zones, the third filter zone can ensure filtration. The third filter zone has a certain height difference relative to the first filter zone, which can also effectively reduce the impact of thick filter cake on the normal filtrate of the third filter zone.

[0020] Preferably, the support portion further comprises:

[0021] A third filtering area is provided at an end of the supporting portion;

[0022] There is a vertical height difference between the third filter area and the first filter area, and a liquid guide filter element is arranged in the liquid guide port.

[0023] By adopting the above technical solution, when the volume of the solution to be filtered is not large, the overall liquid level is low, and the liquid above the third filter zone can quickly enter the filtrate cavity and pass through the liquid guide filter element in the liquid guide port to realize filtration, thereby improving the overall filtration efficiency.

[0024] Preferably, the second filter area is arranged to be inclined toward one side of the inner base.

[0025] By adopting the above technical solution, the inclined second filter zone firstly ensures the strength of the support part with the inclined support structure, and secondly, when the filter cake is thick, the inclined setting reduces solid accumulation and has effective filtering performance.

[0026] Preferably, at least one liquid guide port is provided.

[0027] By adopting the above technical solution, when multiple liquid guide ports are provided, in addition to increasing the filtrate efficiency, the filtrate can also be collected in different zones under characteristic working conditions.

[0028] Preferably, the outer base has an arc-guiding surface at the outer edge.

[0029] By adopting the above technical solution, the setting of the arc guide surface facilitates quick fitting with the inner wall when connected to the reaction container.

[0030] Preferably, the support portion and the inner base are connected by welding or in a detachable manner.

[0031] By adopting the above technical solution, the fixed connection of the support part is suitable for use in devices with relatively complex working conditions, while the detachable connection is easy to replace and is suitable for environments with simple working conditions.

[0032] In order to improve the filtering effect of solid-liquid separation, the second purpose of the present application is to provide a reaction device.

[0033] A reaction device provided in this application adopts the following technical solution:

[0034] A reaction device comprises a reaction chamber and a filtering component arranged in the reaction chamber.

[0035] By adopting the above technical solution, when the solid particles in the reaction device are fine and the permeability is poor, the filter assembly can have multiple filter areas, and the filter cake formed is limited to the surface of the first filter element, without affecting the filtering execution of the second filter area and the third filter area, so that the overall filtration can be ensured to be effective. When filtering a normal solution, the filtering effect can be improved by setting multiple filter areas.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] By providing the second filter area and the third filter area in addition to the first filter area, the filtering effect can be effectively guaranteed when the solution contains finer solid particles and has a poor transmittance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The present application is further described in detail below in conjunction with the accompanying drawings.

[0047] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of this application. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items. Embodiment 1

[0049] Figure 1 and Figure 2 The overall structure of a filter assembly is shown, which can be used in working conditions where the solid particles are fine and the permeability is poor. The filter assembly includes an outer base 10, at least one inner base 20, and a support portion 30 connected to the inner base 20. The outer base 10 is a closed structure. In this embodiment, the outer base 10 is roughly circular in outline, and of course the outer contour depends on the working conditions under which it is installed. As for the closed area enclosed by the outer base 10, the inner base 20 has at least one. In this embodiment, the inner base 20 is set as a single example. The two ends of the inner base 20 are connected to the inner side wall of the outer base 10 and the closed area is divided into two first filter areas 11. The first filter element is installed in the corresponding first filter area 11. When the inner base 20 is set more than one, the closed area can be divided into multiple first filter areas 11, and different types of solid-liquid separation processes can be independently realized in specific working conditions.

[0050] The support portion 30 is connected to the end of the inner base 20 and extends upward from the end. In this embodiment, the support portion 30 is generally trapezoidal, and the interior is an overhead structure to form a filtrate chamber 33, and the two sides are connected to the filtrate chamber 33 to form a second filter area, and a second filter element is arranged in the second filter area.

[0051] The support portion 30 also has a top which is open to form a third filter area 34. A third filter element is disposed in the third filter area 34 and the third filter area 34 is also connected to the filtrate chamber 33. There is a height difference H between the third filter area 34 and the first filter area 11, and the height difference H is determined according to the volume of the liquid to be separated.

[0052] In addition, the two side surfaces of the support portion 30 have an inclined angle A with the vertical plane, and the inclined angle A is between 5-10 degrees, that is, an inclined support structure is formed to ensure the strength of the support portion 30, and to ensure that as few solid particles as possible are attached to the surface of the second filter element to form a filter cake.

[0053] In this embodiment, the support portion 30 and the inner base portion 20 are fixed by welding. Of course, the support portion 30 and the inner base portion 20 can also be detachably connected by a flange.

[0054] Shared Reference Figure 2 and Figure 3The inner base 20 is provided with at least one liquid guide port 21 in the middle region, and the liquid guide port 21 is connected with the filtrate cavity 33. In this embodiment, a plurality of filtrate ports are provided, and in certain working conditions, the plurality of liquid guide ports 21 can also realize independent filtration. Embodiment 2

[0055] See also Figure 4 , a filter assembly, which differs from the first embodiment in that the third filter area 34 is an open structure, and a liquid guide filter mesh 22 is added in the liquid guide port 21. This is applied when the solution capacity is not very large, the third filter area 34 at the top can quickly and in small amounts pass through the liquid, so that the liquid level of the solution can drop quickly, and the liquid guide filter mesh 22 is mainly used to filter a small portion of the solution introduced by the third filter area 34. Embodiment 3

[0056] Shared Reference Figure 5 and Figure 6 , a filter assembly, which differs from the first embodiment in that the inner base 20 is located in the closed area of ​​the outer base 10 and is isolated, so that only one first filter area 11 is formed between the outer base 10 and the inner base 20. When the number of inner bases 20 exceeds one, the area of ​​the first filter area 11 is gradually reduced, and the corresponding support portion 30 is set to be in a frustum shape, and the second filter element is connected end to end. When the permeability of the solid is extremely low, the first filter area 11 will accumulate solid particles very quickly to form a filter cake. By setting multiple inner bases 20, the second filter area and the third filter area 34 are used to achieve solid-liquid separation. Embodiment 4

[0057] See also Figure 7 A reaction device includes a main body 40, wherein a reaction chamber is provided in the main body 40, and a filter assembly as described in any one of Embodiments 1 to 3 is installed in the reaction chamber. The outer base 10 of the filter assembly has an arc guide surface 13 at its outer edge, and the arc guide surface 13 is in conflict with the inner wall of the reaction chamber, and the filter assembly can be installed by a snap-fit ​​form or by welding.

[0058] The reaction chamber is divided by the filter assembly and forms a drainage chamber 42 in the lower half area. The drainage chamber 42 is connected to a drainage pipe. The filtrate passes through the filter assembly and enters the drainage chamber 42 and is then led out.

[0059] During actual filtering operations, when the solid particles in the solution are fine and the permeability is low, the particles will quickly accumulate on the surface of the first filter element to form a filter plate of a certain thickness. The filtrate in the general solution accounts for more than 90% of the total solution volume. After precipitation, most of the filtrate passes through the second filtrate area and the third filtrate area of ​​the support part 30 into the filtrate chamber 33, and finally enters the drainage chamber 42 from the liquid guide port 21, so that the filtrate process can be carried out effectively and efficiently.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
