Abstract
The utility model discloses a filter unit for a feed opening and a discharge opening of a grinding machine. The filter unit comprises a metal tube and filter screens, and is characterized in that outer threads are formed on the outer surface of one end of the metal tube, inner threads are formed on the inner surface of the other end of the metal tube, and the filter screens are fixed in the metal tube. The filter unit has the advantages that the filter screens with different mesh numbers are respectively used for filtering and defoaming a feed tube and a discharge tube; the filter screens are fixed on the metal tube effectively by metal rings, and a phenomenon that the filter screens deflect due to over high liquid flow rate during feeding and discharging is prevented; and both ends of the metal tube are provided with the threads, so that joints cannot leak, and a plurality of filter screens can be arranged on the metal tube.
Description
Technical field
The utility model relates to a kind of filter, particularly a kind of feed inlet and outlet filter of grinder.
Background technology
The production technology of mould release, mainly be adopt horizontal sand mill to powder material grind, refinement, reaching the requirement in the prescription design, and to all raw materials well disperse, mixing.In this production process, mainly have following 2 problems: (1) this sand mill charging aperture is not provided with filter, raw material is not carried out preliminary sieving, may cause loss to disk in the machine owing to the sneaking into of some hard impurity; (2) contain high alveolitoid material in the raw material, this model sand mill discharging opening only goes out the material screen circle, and the product foam of producing is abundant, and is difficult to eliminate, and causes packing of product difficulty, reduces production efficiency greatly.
Before this, to these problems, take 2 measures: filtered through gauze is adopted at feed inlet and outlet in (1); (2) in product, add antifoaming agent.But poor effect, gauze is bad fixing, cause easily to leak outside, and defoaming is not good, and the interpolation of antifoaming agent is bigger to the performance of products influence, can cause product unstable, repeatedly quality abnormal occurs.
Summary of the invention
The utility model provides a kind of feed inlet and outlet filter of grinder; Through one deck filter screen is set at charging aperture, at discharging opening multistorey strainer mesh is set, thereby raw material is played filtration; Product after grinding is played the effect of froth breaking, solved the problem of above-mentioned existence.
The utility model adopts following technical scheme to realize: a kind of feed inlet and outlet filter of grinder; Comprise metal tube and filter screen, it is characterized in that the outer surface of an end of said metal tube has external screw thread; The inner surface of the other end has internal thread, and said filter screen is fixed in the metal tube.
Preferably, the total length of said metal tube>2a, said a is the reach of discharge nozzle.
Further, said filter screen is fixed on the female end of metal tube.
Preferably, the total length of said metal tube>2A, said A is the reach of feed pipe.
Further, said filter screen is fixed on the male end of metal tube.
Preferably, also comprise a quoit, said quoit is fixed in the metal tube, and is fixedly connected with filter screen.
Preferably, the welding of said metal tube and filter screen is fixing.
The beneficial effect of the utility model is that the filter screen of employing different meshes plays the effect of filtration and froth breaking respectively to feed pipe, discharge nozzle; Adopting quoit effectively filter screen to be fixed on the metal tube, prevent that flow rate of liquid is excessive when input and output material, is that screen location squints; Metal tube adopts the both-end screw thread, can guarantee that the junction do not reveal, and realizes a plurality of expansions of filter screen.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Shown in Fig. 1-5, a kind of feed inlet and outlet filter of grinder comprises metal tube 1 and filter screen 3; The outer surface of one end of metal tube 1 has external screw thread 12; The inner surface of the other end has internal thread 11, and filter screen 3 welds through quoit 2 and metal tube 1, thereby is fixed in the metal tube 1.
Shown in Fig. 1-2,, adopt total length at the filter of charging aperture>metal tube 1 of 2A; And go out external screw thread at the outer surface car of filter screen 3 ends; Inner surface car at the other end goes out internal thread, and the internal and external screw thread length of metal tube 1 is consistent with inlet internal thread 41 length of feed pipe 4, is A; Its pitch also will be consistent with internal thread 41 pitch of feed pipe 4; The external screw thread 12 of metal tube 1 is complementary with the internal thread 41 of feed pipe 4.During production, be threaded to the arrival end of feed pipe 4 in external screw thread 12 ends with metal tube 1,, guarantee that the raw material of junction is not revealed, can be when charging raw material be played the effect of filtration, the protection production equipment the porch that is threaded to feed pipe 4 in the filter screen 3.
Shown in Fig. 3-5,, adopt total length at the filter of discharging opening>metal tube 1 of 2a; And go out internal thread at the inner surface car of filter screen 3 ends; Outer surface car at the other end goes out external screw thread, the internal and external screw thread length of metal tube 1 and discharge nozzle 5 to go out interface external thread 51 length consistent, be a; Its pitch also will be consistent with external screw thread 51 pitch of discharge nozzle 5; The internal thread 11 of metal tube 1 is complementary with the external screw thread 51 of feed pipe 5.The same Fig. 3 of the principle of Fig. 4, as long as the internal diameter of n metal tube equals the external diameter of n-1 metal tube, promptly the external screw thread of the internal thread of n metal tube and n-1 metal tube is complementary.When producing, the filter screen end of metal tube is threaded to the port of export of discharge nozzle outward, guarantee that the junction raw material do not reveal, can be when product comes out product be played the effect of filtration, froth breaking, enhance productivity.If want to strengthen defoaming effect, can a plurality of filter screen pipes of making be threaded to the port of export outward successively according to the size order and get final product.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.
