Description

Technical field:

[0002] The utility model relates to a metal cutting chip extruder. Background technology:

[0004] At present, machining workshops need to use emulsion (a high-performance semi-synthetic metalworking fluid used to cool tools and parts) when machining parts. Although the machining equipment is equipped with an emulsion storage tank and a filtering mechanism, after the emulsion has been used for a period of time, a large amount of impurities and oil will be mixed in the emulsion. These impurities and oil will affect the machining quality. Therefore, the emulsion needs to be replaced regularly. The replaced emulsion can be processed through outsourcing, so as to achieve the reuse of the emulsion, but outsourcing the emulsion processing increases the transportation cost and consumes manpower and material resources.

[0005] In addition, during machining, the emulsion will remain on the metal chips. When the metal chips need to be recycled (the metal chips are sold to recycling companies), the residual emulsion will generate extra weight, increasing transportation costs. In addition, the emulsion will seep out during transportation, easily causing the transportation road surface to be slippery, affecting traffic safety, and also causing waste of emulsion.

[0006] Therefore, a Chinese patent for a mechanical machining chip handling mechanism has been retrieved, with publication number CN216183028U, comprising a base and four groups of columns fixed on the upper surface of the base, the top of the column is fixedly connected to a support platform, the upper surface of the support platform is fixedly connected to a support plate, an extrusion box and two groups of support columns, the top of the extrusion box is fixedly connected to a top plate, and four groups of sliding columns are slidably inserted on the left side of the lower surface of the top plate; the mechanical machining chip handling mechanism is used in conjunction with a push plate, a rotating pin, an opening and closing plate, an inclined block and a T-shaped block, so that when the extrusion plate extrude the chips, the inclined block is locked with the T-shaped block, and when the chips are extruded and formed, the push plate pushes the chips out, the inclined block is separated from the T-shaped block, the opening and closing plate is opened, and the chips are pushed out, although the device can automatically push out the extruded chips, thereby improving the production efficiency of the device; but it cannot pre-mix and crush the metal chips, and cannot crush the linear metal chips into fine chips to facilitate subsequent extrusion into blocks. Summary of the invention:

[0008] In view of the above problems, the purpose of the utility model is to provide a metal cutting chip extruder, which is reasonably designed and is conducive to pre-stirring and crushing linear metal cutting chips to facilitate subsequent extrusion into blocks.

[0009] The technical solution of the utility model is as follows:

[0010] The utility model discloses a metal cutting chip extruder, comprising a frame, a storage hopper arranged on the frame, a stirrer, a screw feeder and an extrusion oil cylinder. The frame is provided with an extrusion material chamber, the output end of the screw feeder is communicated with the upper port of the extrusion material chamber, the first side portion of the extrusion material chamber extends into the extrusion pressure head of the extrusion oil cylinder, the second side portion of the extrusion material chamber is provided with an openable and closable gate, the side portion of the extrusion material chamber is provided with a filtering water hole, and the emulsion waste liquid passing through the filtering water hole enters a recovery tank through a pipeline.

[0011] Preferably, the screw feeder and the extrusion cylinder are both arranged horizontally, the extrusion chamber is arranged vertically, the output end of the screw feeder is located at the upper port of the extrusion chamber, and the extrusion pressure head of the extrusion cylinder is located at the lower port of the extrusion chamber.

[0012] Preferably, a vertical hydraulic cylinder is vertically arranged above the extrusion cavity, and an extrusion head of the vertical hydraulic cylinder vertically extends into the upper port of the extrusion cavity.

[0013] Preferably, the agitator is arranged at the discharge port of the storage hopper, and the agitator is used to stir and crush the aluminum slag.

[0014] Preferably, the above-mentioned openable and closable gate is driven by a hydraulic cylinder, and a guide channel for outputting the compressed metal cutting chip compressed block is connected to the outlet end of the openable and closable gate.

[0015] The working principle of the utility model metal cutting chip extruder:

[0016] The metal chips can be broken into linear metal chips by the agitator, and then input into the extrusion cavity from the output end by the screw feeder. The metal chips fall to the lower part of the extrusion cavity under the action of gravity, and then the metal chips are squeezed into compact blocks by the extrusion head driven by the extrusion cylinder and the extrusion effect of the openable and closable gate. At the same time, the residual emulsion waste liquid in the metal chips is also squeezed out and discharged from the filter water hole, finally the metal chips are squeezed into blocks, and the emulsion waste liquid is discharged, which reduces the volume and weight of the metal chips during transportation, reduces the transportation cost, and avoids the residual emulsion waste liquid from wetting the transportation road, thus ensuring the transportation safety.

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The emulsion recycling system comprises a recycling tank 1 for recycling the emulsion generated by each machine in the workshop. The recycling tank 1 can be a square tank made of stainless steel. The recycling tank is connected to the first group of filter barrels 2, the first storage tank 3, the oil-water separator 4, the sterilizer 5, the paper filter 6, the second group of filter barrels 7 and the second storage tank 8 in sequence through a water pump and a pipeline. Figure 1 shown.

[0027] The first storage tank 3 and the second storage tank 8 are both relatively sealed stainless steel square tanks.

[0028] The oil-water separator can be an oil-water separator produced by Guangzhou Dahan Machinery Equipment Co., Ltd.; the sterilizer 5 can be a flow-through ultraviolet sterilizer model UVC125-9 produced by Dingzhou Hengkong Environmental Protection Technology Co., Ltd.; the paper tape filter can be a medium-efficiency filter, bag filter or paper tape filter produced by Dongguan Xingcheng Purification Technology Co., Ltd.

[0029] A first water pump 9 is provided in the recovery tank 1, a first pipeline 10 is connected between the recovery tank 1 and the first group of filter barrels 2, the first water pump 9 is connected to the inlet of the first pipeline 10, and a first control valve 11 is connected in series to the first pipeline 10. After the first control valve 11 is opened, the emulsion waste liquid in the recovery tank 1 can be transported to the first group of filter barrels 2 as the first water pump 9 works.

[0030] A second pipeline 12 is provided between the first group of filter barrels 2 and the first storage tank 3, a first circulation pipeline 13 is provided on the first storage tank 3, and the oil-water separator 4 is connected in series to the first circulation pipeline 13. When the emulsion waste liquid circulates in the first circulation pipeline 13, the grease in the emulsion waste liquid is separated and removed by the oil-water separator 4.

[0031] A third pipeline 14 is provided between the first storage tank 3 and the paper filter 6. The third pipeline 14 is connected in series with a second water pump 15 and the sterilizer 5. The sterilizer 5 can treat bacteria and microorganisms in the emulsion waste liquid.

[0032] A fourth pipeline 17 is connected between the paper tape filter 6 and the second storage tank 8, and a third water pump 18 and the second group of filter barrels 7 are connected in series to the fourth pipeline 17. The paper tape filter 6 can filter finer impurities in the emulsion waste liquid, and the second group of filter barrels 7 can further filter impurities in the emulsion waste liquid.

[0033] The second storage tank 8 is provided with a second circulation pipeline 19, and the second circulation pipeline 19 is serially connected with a third water pump 20 and a second sterilizer 21. Secondary sterilization is performed by the second sterilizer. The second sterilizer can also be a flow-through ultraviolet sterilizer model UVC125-9 produced by Dingzhou Hengkong Environmental Protection Technology Co., Ltd. Since the volume of the second storage tank 8 is large, the emulsion in the second storage tank 8 sometimes needs to be stored for a long time. Therefore, the second sterilizer can kill bacteria or microorganisms generated by long-term storage; the second storage tank 8 outputs the filtered emulsion through the fourth water pump 22 and the output pipeline.

[0034] In order to achieve a good filtering effect, the first group of filter barrels 2 and the second group of filter barrels 7 each include two filter barrels connected in series, and the filter barrel includes a cylindrical barrel body with a liquid inlet and a liquid outlet. A filter screen is provided in the cylindrical barrel body between the liquid inlet and the liquid outlet. The filter screen can be a metal filter screen and a nylon filter screen, and the mesh size of the filter screen is 100 microns.

[0035] In order to prevent the emulsion in the second storage tank from sedimentation and deterioration, a peristaltic pump 23 is connected to the second storage tank 8 through a fifth pipeline. Air is intermittently filled into the second storage tank 8 through the peristaltic pump 23 to disturb the emulsion in the second storage tank and prevent the emulsion from sedimentation and deterioration. The peristaltic pump can be a type 65 peristaltic pump produced by Zhengzhou Erqi District Yubang Machinery Co., Ltd.

[0036] Preferably, in order to realize the recirculation filtration of the emulsion in the second storage tank, a sixth pipeline 24 is connected between the first pipeline 10 and the fourth water pump 22, and a second control valve 25 is connected in series to the sixth pipeline. By opening the second control valve 25 and the fourth water pump 22, the emulsion in the second storage tank can be returned to the first pipeline 10, and the filtration process can be started again from the beginning, so as to be used when qualified filtration cannot be achieved after one treatment.

[0037] The working principle of the utility model emulsion recovery and reuse system:

[0038] The emulsion waste liquid generated by the processing workshop is collected into the recovery tank through the pipeline. The emulsion waste liquid in the recovery tank is transported through the first water pump and the first pipeline through the first group of filter barrels and enters the first storage tank. The emulsion waste liquid in the first storage tank is removed from the oil by the oil-water separator, and then is transported through the second pipeline and the second water pump and sterilized in the sterilizer before entering the paper tape filter. In the paper tape filter, it is filtered by the paper tape (or paper bag) to further filter out impurities, and then passes through the third pipeline, the third water pump and the second group of filter barrels, and then enters the second storage tank. The emulsion in the second storage tank is sterilized by the second circulation pipeline and the second sterilizer. Finally, the treated emulsion is output to the workshop machining equipment through the fourth water pump and the output pipeline.

[0039] Advantages of the utility model emulsion recovery and reuse system:

[0040] 1. The emulsion recycling and reuse system of this application does not use ozone and acidic deep demulsifiers and other materials, so it will not produce negative pressure effects on the surrounding environment and staff;

[0041] 2. The emulsion recovery and reuse system of the present application eliminates the need for outsourcing processing of the emulsion waste from workshop machining, thereby saving transportation costs and labor costs.

[0042] In order to treat the residual emulsion waste liquid in the metal cutting chips and compress the metal cutting chips into blocks (after being compressed into blocks, the volume is small and there is no residual emulsion waste liquid, which is convenient for transportation), a metal cutting chip extruder A is provided beside the recovery tank 1. The metal cutting chip extruder A is as follows: Figure 2 As shown, the metal cutting chip extruder A comprises a frame A1, a storage hopper A2 arranged on the frame, a stirrer A3, a screw feeder A4 and an extrusion cylinder A5, and the frame A1 is provided with an extrusion chamber A6.

[0043] The storage hopper A2 is used to hold metal cuttings processed by machining equipment. The linear metal cuttings can be broken up by the agitator A3, and the screw feeder A4 can push the metal cuttings dropped from the storage hopper A2 to the output end.

[0044] The output end of the screw feeder A4 is communicated with the upper port of the extrusion chamber A6, the first side portion of the lower portion of the extrusion chamber is extended with the extrusion pressure head A7 of the extrusion oil cylinder A5, the second side portion of the extrusion chamber A6 is provided with an openable and closable gate A8, the side portion (specifically the lower side portion) of the extrusion chamber is provided with a filtering water hole A9, the emulsion waste liquid passing through the filtering water hole A9 can enter the recovery tank 1 through the pipeline (to realize the recovery of the residual emulsion waste liquid), when working, the metal cuttings are input into the extrusion chamber A6 by the screw feeder A4, the metal cuttings fall to the lower portion of the extrusion chamber due to the action of gravity, and then the extrusion pressure head A7 driven by the extrusion oil cylinder A5 and the openable and closable gate A8 squeeze the metal cuttings into compact blocks, and at the same time, the residual emulsion waste liquid in the metal cuttings is also squeezed out and discharged from the filtering water hole A9.

[0045] Specifically, the screw feeder A4 and the extrusion cylinder A5 are both arranged horizontally, and the extrusion chamber A6 is arranged vertically (such as Figure 3-5 As shown in the figure), the output end of the screw feeder A4 is located at the upper port of the extrusion cavity, and the extrusion pressure head A7 of the extrusion cylinder A5 is located at the lower port of the extrusion cavity.

[0046] In order to facilitate the metal cutting chips located at the upper part of the extrusion material chamber A6 to be pushed into the lower part more thoroughly, a vertical hydraulic cylinder A10 (such as Figure 3-5 As shown in the figure), the extrusion head of the vertical hydraulic cylinder vertically extends into the upper port of the extrusion cavity A6. Under the action of the extrusion head of the vertical hydraulic cylinder A10, the metal cutting chips output by the output end of the screw feeder A4 are pushed down into the lower part of the extrusion cavity A6.

[0047] Specifically, the agitator A3 is arranged at the discharge port of the storage hopper A2. The agitator A3 is used to stir and crush the linear metal cuttings. The agitator A3 includes a central rotating shaft driven by a motor and a plurality of support rods arranged on the central rotating shaft. When the central rotating shaft rotates, the support rods can break the linear metal cuttings into shorter metal cuttings.

[0048] Specifically, the above-mentioned openable and closable gate A8 is driven by a hydraulic cylinder A12, and a guide channel A11 for outputting compressed metal cutting chip blocks is connected to the output end of the openable and closable gate. The openable and closable gate has two working positions. When the openable and closable gate is located at the lowermost position, it can cooperate with the extrusion ram A7 to compress the metal cutting chips. When the openable and closable gate is located at the uppermost position, the extrusion ram A7 can continue to push the compression into blocks to achieve output from the guide channel A11.

[0049] The utility model metal cutting chip extruder A can break part of the metal cutting chips in linear shape through a stirrer, and then input the metal cutting chips into the extrusion material chamber from the output end thereof by a screw feeder, and the metal cutting chips fall to the lower part of the extrusion material chamber under the action of gravity, and then the metal cutting chips are squeezed into compact blocks by the extrusion pressure head driven by the extrusion oil cylinder and the extrusion action of the gate that can be opened and closed, and the residual emulsion waste liquid in the metal cutting chips is also squeezed out and discharged from the filtering water hole, finally realizing the extrusion of the metal cutting chips into blocks, and the emulsion waste liquid can be discharged at the same time, thereby reducing the volume and weight of the metal cutting chips during transportation, reducing the transportation cost, and avoiding the residual emulsion waste liquid from wetting the transportation road, thereby ensuring the transportation safety.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
