Technical Field
[0001] The utility model belongs to the technical field of additive manufacturing, and in particular relates to a detection device for a mobile ash bucket of a circulating filtration system. Background Art
[0002] In additive manufacturing equipment, the basic process of the circulating filtration system is as follows: an air inlet and outlet are set in the front and rear directions of the powder surface for selective laser sintering; the powder spreading mechanism spreads a layer of powder material on the upper surface of the formed part in the forming cylinder; the galvanometer system controls the laser to scan the solid part according to the interface contour of the layer, so that the powder melts and bonds with the formed part below; when a layer of cross section is sintered, the workbench drops one layer of thickness, and the powder spreading roller spreads a layer of uniform and dense powder on it to perform scanning and sintering of a new layer of cross section. In this layer-by-layer stacking process, smoke and dust will be generated due to laser hot melting; the smoke and dust need to be collected into the filter through the air inlet (suction), and the filtered clean air is blown out from the air outlet, forming a continuously circulating wind field during the scanning and sintering process;
[0003] In the circulating filtration system, the filter is composed of N fast plastic-sintered plate filter elements, which divide the entire filter chamber into two parts. The air with smoke becomes clean air after filtration. At this time, more and more active metal smoke will accumulate on the plastic-sintered plate after several filtrations. The smoke is collected by backblowing into the ash bucket below. Due to the characteristics of active metal smoke, it is flammable and explosive. The oxygen content in the bucket will be reduced by filling it with inert gas to ensure that it does not burn. However, when the ash residue accumulates to a certain level in the ash bucket, it needs to be replaced. At this time, the ash bucket is removed from the equipment and transferred. In this process, since the ash bucket assembly is disconnected from the equipment, the status of the ash bucket is unknown, and the ash bucket is a closed component. There is a risk of ignition and explosion when the temperature and material level in the ash bucket cannot be monitored in real time. The operator cannot detect the abnormality in time, which poses a safety hazard. Utility Model Content
[0004] In order to solve the above-mentioned technical problems existing in the prior art, the utility model provides a detection device for a mobile ash bucket. The detection device for the mobile ash bucket can monitor the ash residue in the closed ash bucket in real time during the process of the ash bucket being separated from the circulation filtration system and transported and transferred. If the internal temperature is abnormal, personnel can evacuate in time to ensure the personal safety of the operator; at the same time, it can also play a sensor detection role during the ash residue treatment process (immersion treatment) to ensure that the ash bucket sensor is normal after cleaning before it is replaced on the equipment for use.

[0020] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the following will be further described in detail with reference to the accompanying drawings and specific embodiments.
[0021] like Figure 1 and Figure 2As shown, the detection device for the mobile ash bucket of the present embodiment is used to perform real-time detection on the ash bucket of the circulating filtration system in the additive manufacturing equipment. The detection device includes a suitcase, and a first monitoring display instrument 4, a second monitoring display instrument 3, a battery 5 with a charge display, a switch 6 and a connecting component for connecting the ash bucket 10, which are embedded in the suitcase. The first monitoring display instrument 4 is used to display the real-time material level in the ash bucket 10, and the second monitoring display instrument 3 is used to display the real-time temperature of the ash bucket 10; the battery 5 supplies power to the first monitoring display instrument 4 and the second monitoring display instrument 3; the switch 6 is used to control the opening or closing of the inspection device.
[0022] The connection assembly includes an aviation socket 7 and a thermocouple connection socket 8. The aviation socket 7 is connected to the aviation plug on the ash bucket 10, and is used to transmit and display the data of the material level sensor on the ash bucket 10 to the first monitoring display instrument 4; the thermocouple connection socket 8 is connected to the thermocouple connection plug on the ash bucket 10, and is used to transmit and display the data of the temperature sensor on the ash bucket 10 to the second monitoring display instrument 3.
[0023] Preferably, when the ash bin 10 is somewhat far from the detection device, a cable is connected between the aviation socket 7 and the aviation plug; and a cable is connected between the thermocouple connection socket 8 and the thermocouple connection plug. The number of these cables can be one or more, and the specific number can be selected based on the distance between the ash bin 10 and the detection device.
[0024] The detection device further includes a charging interface 9 , so that an external power source can charge the battery 5 through the charging interface 9 .
[0025] In order to make the layout of the detection device reasonable and convenient for users to view data, it is further preferred that the aviation socket 7, thermocouple connection socket 8 and charging interface 9 are embedded in the rear panel of the suitcase from top to bottom; the first monitoring display instrument 4 and the second monitoring display instrument 3 are embedded in the upper part of the front panel of the suitcase, the battery 5 with power display is embedded in the suitcase and the power is displayed on one side of the lower part of the front panel, and the switch 6 is set on the other side of the lower part of the front panel.
[0026] In a specific implementation, the switch 6 is a rocker-shaped switch 6 ; the battery 5 is a 24V lithium battery 5 .
[0027] In another specific embodiment, the suitcase includes an upper shell 1, a lower shell 2, and a handle. The upper shell 1 and the lower shell 2 are connected by a transition plate and a plurality of screws to form a box structure, and the handle is provided on the top of the upper shell 1. Of course, the suitcase can also be connected by the upper shell 1 and the lower shell 2 by buckles or other means, which are not limited here.
[0028] The ash bucket 10 of the circulating filtration system in the additive manufacturing equipment is mainly used to collect the smoke and dust generated by the additive manufacturing equipment during the sintering process; the dust falls into the inside of the ash bucket 10 after being filtered by the circulating filtration system; when connected to the equipment, the inside of the ash bucket 10 is protected by inert gas. However, when the ash bucket 10 needs to be cleaned, it is separated from the equipment, and the ash bucket 10 loses the protection of the inert gas filling. Since the collected ash is a substance that has the risk of spontaneous combustion in the air, it is uncontrollable after being separated from the equipment. After disconnecting from the equipment, the ash bucket 10 is connected to the aviation socket 7 of the detection device of the mobile ash bucket 10 of this application through an aviation plug, and is connected to the thermocouple connection socket 8 of the detection device through a thermocouple connection plug, such as Figure 3 As shown, by pressing the boat-shaped switch 6, the material level and temperature status inside the ash bucket 10 can be actually detected, so that the temperature and material level status inside the ash bucket 10 can be actually monitored during the ash cleaning and transportation process; so that the operator can predict whether there is smoldering inside the ash bucket 10 by observing the first monitoring display instrument 4 and the second monitoring display instrument 3, avoid risks in advance, and greatly ensure the personal safety of the operator.
[0029] At the same time, the ash bucket 10 containing ash residue needs to be filled with water in an open area after being left still for a certain period of time. Tap water is injected from the top of the ash bucket 10 and then overflows through the pneumatic overflow valve. During this process, the temperature and level sensor of the ash bucket 10 are in a relatively harsh environment; after the ash bucket 10 is cleaned after the water injection treatment, it can be connected to the detection device of the ash bucket 10. If the sensor is damaged or fails, the first monitoring display instrument 4 and / or the second monitoring display instrument 3 will report an error, so that it can be judged whether the sensor can meet normal use requirements after the water injection treatment, thereby ensuring the usability of the ash bucket 10 sensor that is repeatedly replaced on the equipment, and also ensuring the stability of laser sintering printing.
[0030] The above embodiments are merely preferred implementations of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention should be included in the scope of protection of the present invention. It should be noted that certain modifications and alterations that do not depart from the principles of the present invention should be considered as included in the scope of protection of the present invention.
