Description

Technical Field

[0001] The utility model belongs to the field of blanking systems, and more specifically relates to a graphite crucible blanking system. Background Art

[0002] Graphite crucible, also known as copper molten bag, copper molten bag, etc., refers to a type of crucible made of graphite, clay, silica and wax stone as raw materials. Graphite crucible is mainly used for smelting non-ferrous metals such as copper, brass, gold, silver, zinc and lead and their alloys.

[0003] At present, during the use of graphite crucibles, after metal smelting, the graphite crucible is generally placed above a cooling tank. The molten metal is discharged from the leakage hole at the bottom by gravity and falls into the cooling pool for cooling. This not only causes part of the raw materials to stick to the inner wall of the crucible, causing waste, but also the dripping speed is slow, resulting in low production efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a graphite crucible feeding system which can solve the above problems.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is:

[0006] A graphite crucible unloading system includes a crucible body and a rapid unloading device. The bottom surface of the crucible body is provided with a plurality of leakage holes. The rapid unloading device includes an air pump and a handpiece provided at the output end of the air pump. The handpiece can be engaged with the crucible body to form a cavity. The plurality of leakage holes and the air pump are respectively connected to the cavity. The size of the cavity can be adjusted by moving the handpiece up and down.

[0007] In a specific embodiment of the present invention, a groove for accommodating molten material is provided in the crucible body, and a protrusion and an annular groove are provided on the side of the handpiece corresponding to the crucible body. The handpiece can be used to make the protrusion reciprocate up and down in the groove.

[0008] In a specific embodiment of the present invention, a plurality of leakage holes are evenly spaced and arranged on the bottom surface of the groove, and air holes are provided on the protrusion.

[0009] In a specific embodiment of the present invention, the width of the annular groove is set corresponding to the thickness of the side wall of the crucible body.

[0010] In a specific embodiment of the present invention, the depth of the annular groove is greater than the height of the crucible body.

[0011] In a specific embodiment of the present invention, the rapid unloading device further includes a connecting pipe for connecting the handpiece and the air pump.

[0012] In a specific embodiment of the present invention, a handle is provided on the side of the handpiece, and the handle is made of a heat-insulating material.

[0013] In a specific embodiment of the present invention, a fixing ring for the connecting tube to pass through is provided at one end of the handle away from the handpiece.

[0014] In a specific embodiment of the present invention, the diameter of the handle gradually increases from one end close to the handpiece to the other end.

[0015] One of the above technical solutions of the utility model has at least one of the following advantages or beneficial effects:

[0016] The utility model provides a handpiece at the output end of the air pump, and then adjusts the cavity size by moving the handpiece up and down. Under the condition that the output power of the air pump remains unchanged, the dripping rate of the molten material in the crucible body can be adjusted by changing the pressure in the cavity, thereby not only avoiding the adhesion of raw materials to the inner wall of the crucible body and causing waste, but also further improving production efficiency.

[0028] Refer to the attached Figure 1 To the attached Figure 4 As shown, a graphite crucible unloading system includes a crucible body 1 and a quick unloading device 2. The quick unloading device 2 includes an air pump 21, a handpiece 22 arranged at the output end of the air pump 21, and a connecting pipe 23 for connecting the handpiece 22 and the air pump 21. The handpiece 22 can be snapped together with the crucible body 1 to form a cavity, and the size of the cavity can be changed by moving the handpiece 22 up and down.

[0029] In one embodiment of the present invention, a plurality of leakage holes 11 are provided on the bottom surface of the crucible body 1, and the plurality of leakage holes 11 and the air pump 21 are respectively connected to the cavity. A groove 12 for accommodating molten material is provided in the crucible body 1, and the plurality of leakage holes 11 are evenly spaced and arranged on the bottom surface of the groove 12. The size of the leakage holes 11 can be adjusted according to the specific product requirements.

[0030] In one embodiment of the present invention, a protrusion 221 and an annular groove 222 are provided on the side of the handpiece 22 corresponding to the crucible body 1, and an air hole 3 is provided on the protrusion 221. The handpiece 22 can be used to make the protrusion 221 reciprocate up and down in the groove 12, so that the size and pressure of the cavity can be changed while the output power of the air pump 21 remains unchanged, so as to adjust the dripping rate of the molten material in the crucible body 1, thereby not only avoiding the raw material from sticking to the inner wall of the crucible body 1 and causing waste, but also further improving the production efficiency of the product.

[0031] In one embodiment of the present invention, the width of the annular groove 222 is set to correspond to the thickness of the side wall of the crucible body 1, which can ensure that the handpiece 22 and the crucible body 1 are smoothly buckled together and have a certain degree of airtightness after the handpiece 22 and the crucible body 1 are buckled together.

[0032] In one embodiment of the present invention, the depth of the annular groove 222 is greater than the height of the crucible body 1, so that it can cooperate with the side wall of the crucible body 1 during the up and down movement of the handpiece 22 to play a limiting role, preventing the handpiece 22 from generating relative displacement in the lateral direction during operation, thereby affecting production efficiency.

[0033] In one embodiment of the present invention, a handle 4 is provided on the side of the handpiece 22. The handle 4 is made of a heat-insulating material, preferably a wooden material, which has a low manufacturing cost and can effectively prevent high temperatures and prevent the operator's hands from being burned.

[0034] In one embodiment of the present invention, the diameter of the handle 4 is gradually increased from one end close to the hand piece 22 to the other end, which can further facilitate the worker's operation and prevent the hand piece 22 from slipping out of the hand.

[0035] In one embodiment of the present invention, a switch valve is provided in the middle position of the connecting tube 23, and a fixing ring 5 for the connecting tube 23 to pass through is provided at the end of the handle 4 away from the handpiece 22. After the connecting tube 23 passes through the fixing ring 5, the connecting tube 23 is limited to prevent the connecting tube 23 from swinging arbitrarily when operating the handpiece 22, thereby improving safety.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
