Description

Technical Field

[0001] The utility model relates to the field of tin powder preparation machine technology, in particular to a high-yield tin powder preparation machine. Background Art

[0002] Tin powder is a powder object, the main component of which is tin, with copper, silver, nickel and other metals added as needed. Tin powder is used to make materials such as solder paste, electrocarbon products, friction materials and oil-containing bearings. The manufacturing process of tin powder mainly includes centrifugal and ultrasonic methods. The centrifugal atomization process of tin powder is usually as follows: put the tin ingot into the tin melting furnace to melt it into liquid, and drop the liquid tin onto a high-speed rotating turntable by controlling the flow rate. The high-speed rotating turntable generates centrifugal force through rotation to throw the liquid metal out to form small balls one by one. The small balls are quickly cooled in an inert gas environment to form spherical tin powder particles.

[0003] After the existing tin powder making machine produces tin powder particles, the inertia of the tin powder particles causes them to float around in the machine body, and finally adsorbed on the top of the tin powder making machine under the action of static electricity without falling off, resulting in a low yield of the tin powder making machine. Therefore, it is necessary to improve the existing tin powder making machine. Utility Model Content

[0004] In view of this, the utility model aims to solve the deficiencies in the prior art, and its main purpose is to provide a high-yield tin powder preparation machine, which can effectively solve the problem of low yield of the existing tin powder manufacturing machine, in which tin powder particles are adsorbed on the top of the tin powder manufacturing machine under the action of static electricity and do not fall off.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-yield tin powder preparation machine comprises a body, a tin melting furnace, a converter, a conveying pipe, a driving mechanism, a turntable and a knocking mechanism; the body has an atomizing chamber and a collecting chamber, the atomizing chamber is located above the collecting chamber and is connected with the collecting chamber; the tin melting furnace is arranged outside the body; the converter is arranged in the atomizing chamber and is connected with the tin melting furnace through a pipeline; the conveying pipe is arranged in the atomizing chamber, the conveying pipe extends up and down, and the input end of the conveying pipe is connected with the converter; the driving mechanism is arranged at the connection point between the atomizing chamber and the collecting chamber and is located below the output end of the conveying pipe; the turntable is rotatably arranged on the driving mechanism and driven to rotate by the driving mechanism, and the turntable is located below the output end of the conveying pipe; the knocking mechanism is arranged on the top of the body.

[0007] As a preferred solution, the top of the body is hemispherical, and the knocking mechanism is located on the axis of the center of the sphere of the top of the body, so that when the knocking mechanism knocks on the top of the body, the force on the top of the body is more balanced.

[0008] As a preferred solution, the striking mechanism is a pneumatic hammer.

[0009] As a preferred solution, the center of the turntable is located directly below the output end of the conveying pipe.

[0010] As a preferred solution, the lower end of the atomization chamber is in a cone shape with an inner diameter gradually decreasing from top to bottom, so as to facilitate the tin powder particles to enter the collection chamber from the atomization chamber.

[0011] As a preferred solution, a groove is provided on the top of the machine body, and a baffle made of a transparent material is embedded in the groove, so that the staff can observe the situation inside the machine body through the baffle.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] The turntable is rotatably arranged on a driving mechanism and driven to rotate by the driving mechanism. The turntable is located below the output end of the conveying pipe, and a knocking mechanism is arranged on the top of the machine body. When the tin liquid falls onto the rotating turntable, the centrifugal force will atomize the tin liquid. After the atomized tin liquid is cooled, tin powder particles will be formed. Some of the tin powder particles are adsorbed on the top of the machine body due to static electricity during the floating process. At this time, the knocking mechanism regularly knocks on the top of the machine body, causing the top of the machine body to vibrate, thereby causing the tin powder particles to detach from the top of the machine body and fall into the collection chamber, thereby effectively improving the yield of the tin powder.

[0024] The body 10 has an atomizing chamber 11 and a collecting chamber 12, wherein the atomizing chamber 11 is located above the collecting chamber 12 and is connected to the collecting chamber 12; in the present embodiment, the top of the body 10 is hemispherical; in addition, the lower end of the atomizing chamber 11 is conical with an inner diameter gradually decreasing from top to bottom, so as to facilitate the entry of tin powder particles from the atomizing chamber 11 into the collecting chamber 12; an embedding groove 13 is provided on the top of the body 10, in which a baffle 14 made of a transparent material is embedded, and a staff member observes the situation inside the body 10 through the baffle 14.

[0025] The tin melting furnace 20 is disposed outside the machine body 10 .

[0026] The transfer furnace 30 is disposed in the atomization chamber 11 and communicated with the tin melting furnace 20 through a pipeline 81 .

[0027] The delivery pipe 40 is disposed in the atomization chamber 11 . The delivery pipe 40 extends up and down, and an input end of the delivery pipe 40 is connected to the transfer furnace 30 .

[0028] The driving mechanism 50 is disposed at the connection point between the atomizing chamber 11 and the collecting chamber 12 and is located below the output end of the delivery tube 40 .

[0029] The turntable 60 is rotatably disposed on the driving mechanism 50 and driven to rotate by the driving mechanism 50 . The turntable 60 is located below the output end of the delivery pipe 40 . In the present embodiment, the center of the turntable 60 is located directly below the output end of the delivery pipe 40 .

[0030] The striking mechanism 70 is disposed at the top of the body 10; in the present embodiment, the striking mechanism 70 is located at the axial position of the center of the ball at the top of the body 10, so that when the striking mechanism 70 strikes the top of the body 10, the force on the top of the body 10 is more balanced; and the striking mechanism 70 is a pneumatic hammer.

[0031] The working process of this embodiment is described in detail as follows:

[0032] First, the tin melting furnace 20 melts the tin block into tin liquid and transports it to the transfer furnace 30 through the pipeline 81. Then, the transfer furnace 30 drops the tin liquid onto the rotating turntable 60 through the conveying pipe 40. The centrifugal force will atomize the tin liquid. After cooling, the atomized tin liquid will form tin powder particles. Most of the adsorbed particles will float in the atomization chamber 11 and then fall into the collecting chamber 12. A small part will be adsorbed on the top of the machine 10 due to the effect of static electricity. Then, the knocking mechanism 70 regularly knocks on the top of the machine body 10, and the tin powder particles detach from the top of the machine body 10 and fall into the collecting chamber 12, so that the knocking frequency can be set to knock once every ten seconds or once every fifteen seconds, which can be adjusted according to actual production conditions.

[0033] The design focus of the utility model is that a turntable is rotatably arranged on a driving mechanism and driven to rotate by the driving mechanism, the turntable is located below the output end of the conveying pipe, and a knocking mechanism is arranged on the top of the machine body. When the tin liquid falls on the rotating turntable, the centrifugal force will atomize the tin liquid, and the atomized tin liquid will form tin powder particles after cooling. Some of the tin powder particles are adsorbed on the top of the machine body due to the effect of static electricity during the floating process. At this time, the knocking mechanism regularly knocks the top of the machine body, causing the top of the machine body to vibrate, thereby causing the tin powder particles to detach from the top of the machine body and fall into the collecting chamber, thereby effectively improving the yield of the tin powder.

Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
