Abstract

A grinding filter comprises a top cover, grinding rod and an outer sleeve, wherein, the grinding rod, a hollow tube, is positioned inside the outer sleeve and is provided with a holding frame at the lower part; the bulge arranged on a fixing rack is fixed with the hollow groove arranged on a supporting rod; the inserting column arranged at the bottom of the grinding rod matches with the concave hole at the bottom of the fixing rack; a filtering net is clamped between the holding frame and the fixing rack; the external surface of the fixing rack bottom is a rugged abrasive surface, and the internal bottom of the outer sleeve is also a rugged abrasive surface matching with the external surface of the fixing rack bottom. The utility model has the advantages of that: the grinding filter has three functions i.e. solid crushing, stirring leaching and solid-liquid separation with simple structure and convenient operation and can effectively prevent solvent volatilization with practicality.

Description

Grind filter

Technical field

The utility model belongs to a kind of grinding filter

Background technology

At present, by extracting certain composition in the solid material is a kind of technology commonly used in experiment and the production, extraction comprises solid pulverizing, stirring and leaching, three unit of Separation of Solid and Liquid, need use instrument more during operation, and in the leaching process that uses volatile solvent, exist problems such as solvent evaporates is serious, therefore be necessary to provide a kind of grinding filter, this grinding filter operation is simple, safety.

Summary of the invention

The purpose of this utility model is to provide a kind of grinding filter, and this grinding filter has solid pulverizing, stirring and leaching, three kinds of functions of Separation of Solid and Liquid, and simple in structure, simple and efficient to handle, can effectively prevent solvent evaporates, practicality again.

For achieving the above object, the utility model is taked following technical scheme: this grinding filter, it comprises top cover, milling bar, outer sleeve, described milling bar is positioned at outer sleeve, described milling bar is a hollow tube, there is bracing frame its underpart, and the projection on the fixed mount cooperates fixing with dead slot on the support bar, and the inserting column of the bottom of milling bar shrinkage pool bottom fixed mount matches, between bracing frame and fixed mount, accompany screen pack, the fixed mount bottom outer surface is rugged abradant surface, and the outer sleeve inner bottom part is rugged abradant surface, this abradant surface and fixed mount bottom outer surface relative engagement.

The utility model has the advantages that: this grinding filter has solid pulverizing, stirring and leaching, three kinds of functions of Separation of Solid and Liquid, and simple in structure, simple and efficient to handle, can effectively prevent solvent evaporates, practicality again.

The specific embodiment

As shown in Figure 1,1 is top cover, and it and milling bar end are hinged, if adopt working of plastics, can be directly and the milling bar one-shot forming, and utilize its elasticity to achieve the function of keying, can avoid its loss and pollution again.2 is milling bar, 4 is fixed mount, it cooperates, fixes below milling bar 2, both have the feed liquor breach after cooperating, and screen pack 5 is arranged on the breach, and screen pack is between bracing frame and fixed mount, fixed mount clamps screen pack, in most external is outer sleeve 3, and milling bar can move up and down in outer sleeve, and rotatable.

Shown in Fig. 2 a, Fig. 2 b, milling bar is a hollow milling bar, it has made boss 2-1, there is blank bracing frame 2-3 the boss below, for fixed mount is cooperated with bracing frame, then on the hollow milling bar, dug to cooperate and use dead slot 2-2, for ease of operating milling bar, had asperities 2-5 at the head of milling bar.

Shown in Fig. 3 a, Fig. 3 b, Fig. 3 c, fixed mount has the cylinder of blank 4-1 around making, it and bracing frame 2-3 corresponding matching, and cylinder is provided with the step 4-2 that cooperates with above-mentioned dead slot 2-2, in the dead slot of its insertion bracing frame.This fixed mount has the end, and its outer bottom is promptly made the 4-5 that is uneven so that the abrasive solid particle is made protruding 4-4 on the fixed mount lower, outer perimeter face near the side at the end in the outer sleeve 3, is convenient to grind.Realize in the process of grinding at fixed mount and outer sleeve, be to rotate milling bar to drive fixed mount rotation and grinding, therefore in order to prevent that milling bar and fixed mount from doing relative motion, be provided with a plurality of inserting column 2-4 in the bottom of milling bar, in the bottom of fixed mount a plurality of shrinkage pool 4-3 are set accordingly, this inserting column matches with shrinkage pool, and fixing.

As Fig. 4 a, Fig. 4 b, its inner bottom surface is also made the 3-1 that is uneven.

When above-mentioned bracing frame cooperates with fixed mount, accompany screen pack in the middle of it.

Operating process: will extract raw material during use and put among the outer sleeve, then milling bar is inserted in the outer sleeve, utilize fixed mount bottom and the rugged occlusion portion of outer sleeve inner bottom part that material is ground, afterwards, the top cover of opening on the milling bar adds the required solvent of extraction, the top cover that closes by lifting repeatedly, grinding, is finished leaching process, after extracting end, milling bar is pushed into bottommost, opens top cover, the extract that is oozed out by screen pack can be taken out.

Claims

1, a kind of grinding filter, it is characterized in that: it comprises top cover, milling bar, outer sleeve, described milling bar is positioned at outer sleeve, described milling bar is a hollow tube, there is bracing frame its underpart, projection on the fixed mount cooperates fixing with dead slot on the support bar, the inserting column of milling bar bottom shrinkage pool bottom fixed mount matches, and accompanies screen pack between bracing frame and fixed mount, the fixed mount bottom outer surface is rugged abradant surface, the outer sleeve inner bottom part is rugged abradant surface, this abradant surface and fixed mount bottom outer surface relative engagement
