Description

Technical Field

[0001] The utility model relates to the field of aluminum processing, in particular to an aluminum scrap collection and processing system for a flat ingot sawing machine. Background Art

[0002] A sawing machine is a commonly used device in aluminum processing. When cutting aluminum, it will produce a lot of aluminum chips. In the prior art, these aluminum chips are often collected and briquetting, and the aluminum chips usually need to be filtered before briquetting.

[0003] For example, the patent with authorization announcement number CN208232385U discloses an automatic aluminum chip collection and ingot pressing system, which includes an AGV collection vehicle, an aluminum powder filtering device, a lifting and unloading machine, an aluminum chip conveyor and an aluminum chip ingot pressing machine. When the system is working, the aluminum powder filtering device filters the aluminum chips generated by the CNC machine, and then the filtered aluminum chips are sent to the lifting and unloading machine through the AGV collection vehicle, and then the motor of the lifting and unloading machine drives the box turning rod to flip the material box, so that the aluminum chips in the material box are poured onto the conveyor belt of the aluminum chip conveyor and sent to the aluminum chip ingot pressing machine, but the system structure is relatively complex and occupies a relatively large area.

[0004] For another example, a patent with authorization announcement number CN203683626U discloses an aluminum chip recovery and processing device, which includes a collecting dish, and the collecting dish is connected to a collecting box through a first pipe, a coarse-effect filter is provided in the collecting box, and the collecting box is connected to a blower through a second pipe. When the device is working, after the blower is started, the airflow enters from the inlet of the collecting dish near the contact point between the bottle and the rolling cutter, and enters the collecting box through the pipe. Due to the rapid drop in the flow rate of the airflow, the larger aluminum chips naturally sink onto the pull-out aluminum chip tray, and the micro-aluminum chips slowly pass through the coarse-effect filter with the airflow to filter out the fine aluminum chips. Then the airflow is sent into the cavity by the blower through the pipe and is discharged after being filtered by a high-efficiency filter. However, the device is used for a capping machine, and the aluminum chips generated when the capping machine is working are relatively small. Therefore, the device can complete the collection using a pull-out aluminum chip tray.

[0005] For another example, the patent with authorization announcement number CN207788418U discloses an aluminum chip collection device for a sawing machine, which includes a main collecting box, an auxiliary collecting box, a conveying pipe and a chip suction fan, wherein the input end of the first conveying pipe is connected to the sawing machine, the outlet end of the first conveying pipe is connected to the first-level chip suction fan, the first-level chip suction fan is connected to the second conveying pipe and draws the aluminum chips to the second conveying pipe, the outlet end of the second conveying pipe is connected to the classification box arranged on the top of the collecting bucket, and the second-level chip suction fan is installed on the top of the classification box, the classification box is respectively connected to the main collecting box and the auxiliary collecting box, and the device classifies the aluminum chips into the main collecting box and the auxiliary collecting box according to the weight and size of the aluminum chips under the action of the second-level chip suction fan, but the device only realizes the aluminum chip collection function, and it is not directly connected with the briquetting machine. Therefore, when used, the collected aluminum chips need to be further transferred to the briquetting machine.

[0006] In addition, the aluminum chips after sawing the flat ingot are in filament form, and due to the lubrication effect, the produced aluminum chips are more oily, which will cause the aluminum chips to be more sticky. The aluminum chips are easily stuck together and agglomerated. After agglomerating, the aluminum chips often cannot enter the briquetting machine cavity and be compressed into blocks. This often leads to the formation of a cavity inside the briquetting machine and an alarm prompt. Utility Model Content

[0007] The purpose of the utility model is to provide an aluminum chip collection and processing system for a flat ingot sawing machine, which can be connected to a briquetting machine while realizing aluminum chip collection, and the aluminum chips that are clumped and stuck together will be broken up by an aluminum chip breaking up mechanism when entering the feed chute of the briquetting machine, thereby ensuring that the aluminum chips can enter the briquetting machine to complete the briquetting operation.

[0008] The purpose of this utility model is achieved through the following technical solutions:

[0009] A flat ingot sawing machine aluminum chip collection and processing system comprises a first filter bucket, a second filter bucket and a briquetting machine, wherein a feed pipe is provided on one side of the first filter bucket, and the other side is connected to the lower end of the second filter bucket through a connecting pipe, and the upper end of the second filter bucket is connected to a fan, a vortex guide plate is provided in the first filter bucket, a bag mesh plate is provided in the second filter bucket, a feed trough is provided on one side of the briquetting machine, and an output port at the lower end of the first filter bucket is provided above the feed trough, and an aluminum chip scattering mechanism is provided on the feed trough.

[0010] The aluminum chip scattering mechanism comprises a rotating shaft and a rotation driving device. The rotating shaft is driven to rotate by the rotation driving device, and a scattering rod is provided on the rotating shaft.

[0011] The trough walls on both sides of the feeding trough are inclined surfaces, and a stirring spiral shaft is arranged at the bottom of the feeding trough.

[0012] A feeding spiral shaft is arranged on the inclined surface of the feeding trough close to the briquetting machine cavity.

[0013] The feed pipe is provided with a feed control valve, the connecting pipe is provided with a connection control valve, and the output port at the lower end of the first filter bucket is provided with a first control valve.

[0014] A second control valve and a third control valve are provided at the output port at the lower end of the second filter bucket, an auxiliary conveyor belt is provided at the lower side of the output port of the second filter bucket, and the output end of the auxiliary conveyor belt is provided above the feed trough.

[0015] The first filter hopper is arranged on a first bracket, the second filter hopper is arranged in a cover body, a second bracket is arranged on the lower side of the cover body, and a fan mounting frame for fixing the fan is arranged on one side of the upper end of the cover body.

[0016] An auxiliary air blowing port is arranged on one side of the output port at the lower end of the first filter bucket.

[0017] The first filter bucket and the second filter bucket are provided with a vibrator.

[0018] The advantages and positive effects of the utility model are:

[0019] 1. The utility model can realize docking with the briquetting machine while realizing the collection of aluminum chips, and the aluminum chips that are clumped and adhered together will be dispersed by the aluminum chip dispersing mechanism when entering the feeding trough of the briquetting machine, thereby ensuring that the aluminum chips can enter the briquetting machine to complete the briquetting operation.

[0020] 2. The utility model only utilizes one fan to provide negative pressure for the equipment, which reduces the energy consumption of the equipment. At the same time, the utility model is provided with a vortex guide plate in the first filter bucket to guide the airflow to continuously rotate, thereby extending the residence time of the airflow in the first filter bucket, so that as much aluminum chips as possible can be realized falling under the action of gravity, thereby ensuring the supply of aluminum chips to the briquetting machine. Through experimental tests, it can be known that when the utility model is working, 80% of the aluminum chips in the airflow will fall in the first filter bucket and enter the briquetting machine to complete briquetting.

[0021] 3. The lower end of the second filter bucket of the utility model adopts a double control valve structure, wherein when the upper second control valve is opened and the lower third control valve is closed, a temporary storage bin can be formed between the two control valves to temporarily store aluminum chips, and the situation in which the aluminum chips are sucked back into the system due to the influence of the system negative pressure can be avoided. In particular, the second filter bucket is used as a secondary filter, and the aluminum chips after filtering are relatively light, so it is more necessary to adopt the above-mentioned double control valve structure. When the upper second control valve is closed and the lower third control valve is opened, the aluminum chips in the temporary storage bin are automatically output and fall and are sent to the briquetting machine under the action of an auxiliary conveyor belt, thereby further ensuring the aluminum chip briquetting efficiency.

[0022] 4. The overall structure of the utility model is compact and will not take up too much space. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 6 As shown, the utility model comprises a first filter hopper 2, a second filter hopper 4 and a briquetting machine 5, wherein one side of the first filter hopper 2 is provided with a feed pipe 1, and the other side is connected to the lower end of the second filter hopper 4 through a connecting pipe 3, and the upper end of the second filter hopper 4 is connected to a fan 8, as shown in FIG. Figure 3 As shown, a vortex guide plate 203 is provided in the first filter bucket 2 to guide the airflow to rotate continuously. Figure 4 As shown, a bag mesh plate 402 is provided in the second filter hopper 4 to achieve filtration. The bag mesh plate 402 is a well-known technology in the art, such as patents such as CN207788418U. Figure 5 As shown, the briquetting machine 5 is provided with a feeding trough 502 on one side, and as shown in Figure 1 As shown, the output port at the lower end of the first filter bucket 2 is arranged above the feed trough 502. Figure 5As shown, the feed trough 502 is provided with an aluminum chip scattering mechanism 6, and the aluminum chip scattering mechanism 6 includes a rotating shaft 602 provided with a scattering rod 603. When the utility model is working, the feed pipe 1 is connected to the sawing machine, and the fan 8 is started to provide negative pressure for the equipment. At this time, the airflow containing aluminum chips enters the first filter bucket 2 through the feed pipe 1, and the heavier aluminum chips fall under the action of gravity, and then are output from the output port at the lower end of the first filter bucket 2 and fall into the feed trough 502 of the briquetting machine 5. In addition, as shown in FIG. Figure 3 As shown, the airflow under the guidance of the vortex guide plate 203 will be in a state of continuous rotation in the first filter hopper 2 so that as much aluminum chips as possible can fall under the action of gravity. After testing, it is known that 80% of the aluminum chips in the airflow will fall in the first filter hopper 2 and enter the briquetting machine 5 to complete briquetting, thereby meeting the feeding requirements of the briquetting machine 5. At the same time, the rotating shaft 602 in the aluminum chip scattering mechanism 6 is in a state of alternating forward and reverse rotation, so that the scattering rod 603 on the rotating shaft 602 can scatter the aluminum chips that are clumped together. Figure 1 As shown, the airflow passing through the first filter bucket 2 will enter the second filter bucket 4 along the connecting pipe 3, and as shown in FIG. Figure 4 As shown, the remaining aluminum chips and other filtered materials in the second filter bucket 4 will be filtered out by the bag mesh 402 and temporarily stored in the second filter bucket 4, and the airflow that has finally completed the filtration will be discharged by the fan 8.

[0032] like Figures 5-6 As shown, in this embodiment, the two ends of the rotating shaft 602 are rotatably installed on the straight walls on the left and right sides of the feed trough 502 through bearing seat supports, and the aluminum chip scattering mechanism 6 includes a rotating drive device 601, and the rotating shaft 602 is driven to rotate by the rotating drive device 601. The rotating drive device 601 can adopt an electric motor, a motor and other devices.

[0033] like Figures 5-6 As shown, in this embodiment, the front and rear sides of the feed trough 502 are both inclined surfaces, and the bottom of the feed trough 502 is provided with a stirring screw shaft 501 driven by a first motor to further stir the aluminum chips falling into the feed trough 502. In addition, the feed trough 502 is provided with a feeding screw shaft 503 driven by a second motor to rotate on the inclined surface of the side of the cavity of the briquetting machine 5. The aluminum chips in the feed trough 502 rise along the spiral sheet on the feeding screw shaft 503 and enter the cavity of the briquetting machine 5 to complete the briquetting operation. The briquetting machine 5 is a well-known technology in the art, for example, the briquetting machine in the CN206406486U patent can be used.

[0034] like Figures 1-2As shown, in this embodiment, a feed control valve 101 is provided on the feed pipe 1, a connecting control valve is provided on the connecting pipe 3, and a first control valve 202 is provided at the output port at the lower end of the first filter bucket 2. In this embodiment, the feed control valve 101 and the connecting control valve are used to control the opening and closing of the feed pipe 1 and the connecting pipe 3, and the first control valve 202 is used to control the discharge of the first filter bucket 2.

[0035] And as Figure 2 As shown, in this embodiment, the output port at the lower end of the second filter hopper 4 is provided with a second control valve 401 and a third control valve 403 to control the discharge. The advantage of this design is that since the second filter hopper 4 is a two-stage filter, the weight of the aluminum chips filtered by it is relatively light. If only one control valve is used to control the discharge of the second filter hopper 4, there will be a problem that the aluminum chips will be sucked back into the system due to the negative pressure of the system after the control valve is opened, which will reduce the efficiency of aluminum chip briquetting. The utility model adopts a dual control valve structure of the second control valve 401 and the third control valve 403, and the second control valve 401 and the third control valve 403 are controlled by time-divided differential action. , wherein when the second control valve 401 is opened and the third control valve 403 is closed, a temporary storage bin can be formed between the second control valve 401 and the third control valve 403, and the aluminum chips will be temporarily stored in the temporary storage bin, and the problem of the aluminum chips being sucked back into the system due to the negative pressure of the system can also be avoided. Then the second control valve 401 is closed and the third control valve 403 is opened. At this time, the aluminum chips in the temporary storage bin will fall on an auxiliary conveyor belt and be conveyed to the top of the feed trough 502 of the briquetting machine 5, and then fall into the briquetting machine 5, which further increases the amount of aluminum chips falling into the briquetting machine 5, that is, further improves the aluminum chips briquetting efficiency. In addition, since the first filter hopper 2 is a primary filter, the weight of the aluminum chips filtered out is relatively heavy, so if Figure 1 As shown, in this embodiment, only one control valve is provided at the lower end of the first filter bucket 2, but the utility model can also adopt a double control valve structure at the lower end of the first filter bucket 2 according to actual production needs.

[0036] The above control valves also facilitate offline cleaning and maintenance of the equipment. For example, when a filter bucket is being cleaned, the filter bucket can be isolated by controlling the corresponding control valve to close to prevent the secondary dust generated during cleaning from affecting other parts of the equipment. The above control valves are all well-known technologies in the art and are commercially available products.

[0037] like Figure 1 As shown, in this embodiment, the first filter hopper 2 is arranged on a first bracket 201, the second filter hopper 4 is arranged in a cover body 7, and a second bracket 701 is provided on the lower side of the cover body 7, and a fan mounting frame 702 is provided on one side of the upper end of the cover body 7, and the fan 8 is fixedly mounted on the fan mounting frame 702.

[0038] like Figure 1As shown, the utility model can be provided with an auxiliary blowing port 9 at one side of the output port at the lower end of the first filter hopper 2 according to actual needs. When the aluminum chips fall and scatter, the auxiliary blowing port 9 can output a suitable amount of air to further blow away the filamentary aluminum chips. However, the output air volume of the auxiliary blowing port 9 must ensure that the aluminum chips cannot be blown out of the feed trough 502. Figure 1 As shown, in this embodiment, the rear end of the auxiliary blowing port 9 is connected to the air duct, and the auxiliary conveyor belt on the lower side of the second filter bucket 4 can be arranged above the air duct, and the output end of the auxiliary conveyor belt is arranged above the auxiliary blowing port 9, so that the aluminum chips conveyed by the auxiliary conveyor belt can also be further blown away through the auxiliary blowing port 9 during the process of falling into the briquetting machine 5. The auxiliary conveyor belt is a well-known technology in the art and is a commercially available product, such as can be purchased from Henan Kunwei Machinery.

[0039] In addition, the utility model can also set a vibrator at a suitable position on the first filter bucket 2 and the second filter bucket 4 according to actual needs to avoid adhesion of aluminum chips. The vibrator is a well-known technology in the art, for example, the vibrator in patents such as CN210616909U can be used, or a commercially available product can be used.

[0040] The working principle of the utility model is:

[0041] When the utility model is working, the feed pipe 1 is connected to the sawing machine, and the fan 8 is started to provide negative pressure for the equipment. At this time, the airflow containing aluminum chips enters the first filter bucket 2 through the feed pipe 1, and the heavy aluminum chips fall under the action of gravity, and then are output from the output port at the lower end of the first filter bucket 2 and fall into the feed trough 502 of the briquetting machine 5. Figure 3 As shown, a vortex guide plate 203 is provided in the first filter hopper 2 to guide the airflow to rotate continuously, so that the residence time of the airflow in the first filter hopper 2 can be prolonged, so that as much aluminum chips as possible can be dropped under the action of gravity to meet the feeding requirements of the briquetting machine 5. At the same time, the rotating shaft 602 in the aluminum chip scattering mechanism 6 is in a forward and reverse alternating rotation state, and the scattering rod 603 thereon is used to scatter the aluminum chips that are clumped together, and as shown in FIG. Figure 1 As shown, the utility model can be provided with an auxiliary blowing port 9 at one side of the output port of the first filter hopper 2 according to actual needs. When the aluminum chips are scattered by the aluminum chip scattering mechanism 6, the auxiliary blowing port 9 can output a suitable air volume to further blow away the filamentary aluminum chips. Figure 1 As shown, the airflow passing through the first filter bucket 2 enters the second filter bucket 4 along the connecting pipe 3, and as shown in FIG. Figure 4 As shown, at this time, the remaining aluminum chips and other filtered materials in the second filter bucket 4 will be filtered out under the action of the bag mesh plate 402, and the airflow that has finally completed the filtration will be discharged under the action of the fan 8.

[0042] The utility model can realize the connection with the briquetting machine 5 while realizing the collection of aluminum chips, and the aluminum chips that are clumped and adhered together will be scattered by the aluminum chip scattering mechanism 6 when entering the feeding trough 502 of the briquetting machine 5, so as to ensure that the aluminum chips can enter the briquetting machine 5 to complete the briquetting operation. Figure 1 As shown, the overall structure of the utility model is compact and does not take up too much space.
