Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a filter that automatically recovers raw materials. Background Technology

[0002] Loose-grained raw materials and catalysts are easy to separate after reaction due to their larger particle size. However, some raw materials and catalysts are highly reactive and readily react with oxygen and moisture. Therefore, during collection and recycling, they are easily exposed to air and water, leading to raw material deterioration and catalyst poisoning. This makes recycling and reuse difficult, wastes resources, and increases costs. Furthermore, some reactive raw materials and catalysts can even ignite or explode upon contact with air and moisture, causing significant personal injury and property damage.

[0003] Therefore, there is an urgent need for a filter that automatically recovers raw materials. Utility Model Content

[0004] In view of this, the present invention provides an automatic raw material recycling filter to solve the problems mentioned in the background art, and specifically discloses the following:

[0005] An automatic raw material recycling filter includes a vertical outer tube and a filter inner tube. The filter inner tube includes a filter screen and a filter bend. The filter screen is fixedly installed inside the vertical outer tube, with its top end flush with the top end of the vertical outer tube. The filter screen and the vertical outer tube are coaxially arranged. One end of the filter bend is fixedly connected to the bottom end of the filter screen, and the other end passes through the side wall of the vertical outer tube and extends outward.

[0006] Furthermore, the filter screen is welded to the inside of the vertical outer tube.

[0007] Furthermore, the aperture of the filter screen is φ0.1~15mm.

[0008] Furthermore, the filter screen is a polypropylene perforated plate, a metal woven mesh, or a metal perforated plate.

[0009] Furthermore, the top and bottom outer walls of the vertical outer tube are provided with a first flange, and the outer wall of the extended end of the filter bend is provided with a second flange.

[0010] Furthermore, both the first flange and the second flange are slip-on flanges, quick-opening flanges, or clamp-type flanges.

[0011] Furthermore, a first valve is provided at both the top and bottom of the vertical outer tube, and a second valve is provided at the extended end of the filter bend.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, the reaction liquid in the reactor flows in from the top of the filter screen, and the filtrate flows out from the bottom of the vertical outer tube through the filter screen. Particles of the raw materials and catalyst are trapped within the filter screen. After filtration, the solvent required for the reaction is injected from the protruding end of the filter bend, carrying the particles from the filter screen back into the reactor. This invention allows for the separation of raw material and catalyst particles, enabling their reuse in the reactor. It is low-cost, convenient, quick, simple, practical, safe, and reliable.

[0023] See appendix Figure 1 This utility model discloses an automatic raw material recycling filter, including a vertical outer tube 1 and a filter inner tube 2. The filter inner tube 2 includes a filter screen 21 and a filter bend 22. The filter screen 21 is fixedly installed inside the vertical outer tube 1, and the top of the filter screen 21 is flush with the top of the vertical outer tube 1. The filter screen 21 and the vertical outer tube 1 are coaxially arranged. One end of the filter bend 22 is fixedly connected to the bottom end of the filter screen 21, and the other end passes through the side wall of the vertical outer tube 1 and extends outward.

[0024] In this embodiment, the filter is an integrated device made of the same material, such as polypropylene, carbon steel, stainless steel, titanium steel, or alloy materials.

[0025] In this embodiment, both the vertical outer tube 1 and the filter inner tube 2 are cylindrical. The outer side of the vertical outer tube 1 is also provided with a bracket (not shown in the figure), which can be fixed on the platform or the ground as needed.

[0026] The filter screen 21 is welded to the inside of the vertical outer tube 1.

[0027] In this embodiment, the filter screen 21 adopts a sleeve structure and is welded and fixed to the vertical outer tube 1, which is small in size and occupies little space.

[0028] The aperture of the filter screen 21 is φ0.1~15mm.

[0033] Working principle:

[0034] The top of the vertical outer tube 1 is fixed to the liquid outlet of the reactor, and the filter screen 21 is connected to the liquid outlet of the reactor. After the production reaction is completed, the reaction liquid in the reactor flows in from the top of the filter screen 21, and the filtrate flows out from the bottom of the vertical outer tube 1 after passing through the filter screen 21. The raw material and catalyst particles are intercepted in the filter screen 21. After the reaction liquid is filtered, the solvent required for the reaction is injected from the protruding end of the filter bend 22, which carries the particles in the filter screen 21 back into the reactor, which can be directly used for the next batch of production. The filter screen 21 is restored to its original state and can be directly used for the filtration of the next batch of reaction liquid.

[0035] This invention can quickly separate and recycle reused raw materials or catalysts. It is simple, practical, safe and reliable. In actual use, there is no need to disassemble the filter or add any extra operating steps. It solves the problem of reusing raw materials or catalysts, simplifies the subsequent operation steps of the process, saves resources and reduces production costs.

[0036] The above are merely preferred embodiments of this application and are not intended to limit this application.
