Description

Technical Field

[0001] This utility model relates to the field of industrial sample analysis technology, and in particular, to a moisture crucible cleaning device. Background Technology

[0002] A moisture crucible is used for testing the moisture content of powder samples. To efficiently extract moisture, moisture crucibles are often designed as shallow dishes, available in rectangular or circular shapes. Circular shallow dishes are widely used due to their high positioning accuracy and ease of manufacturing. After moisture testing, a powdery residue of about 3-5 mm in height typically forms at the bottom of the moisture crucible. This residue is loose, dry, free-flowing, and difficult to handle. Currently, negative pressure suction is generally used to remove it. However, simple negative pressure suction cannot completely remove all the powdery residue from the crucible, easily creating cleaning dead zones and failing to completely solve the problem of sample adhering to the bottom of the crucible. Summary of the Invention

[0003] This invention addresses the structural characteristics of a circular shallow dish by designing a moisture crucible cleaning device. Combining negative pressure suction and brush removal, the device achieves both cleaning efficiency and quality, ensuring thorough cleaning of all powdery residues within the moisture crucible.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A moisture crucible cleaning device, comprising:

[0006] frame;

[0007] The rotating assembly, located below the frame, includes a rotating platform for placing a moisture crucible and a drive mechanism for rotating the rotating platform.

[0008] A liftable cleaning assembly is located above the frame and includes a movable cover, a lifting mechanism, a cleaning nozzle, and a cleaning brush. The movable cover is used to fix the moisture crucible, is rotatably connected to the lifting mechanism, and rotates with the moisture crucible. The cleaning nozzle and cleaning brush are located inside the movable cover and are fixedly connected to the lifting mechanism.

[0009] Furthermore, the cleaning nozzle is connected to the discharge pipe, and the discharge pipe is connected to the negative pressure mechanism.

[0010] Furthermore, the cleaning nozzle is boot-shaped, with a circular screw opening at the top and a rectangular nozzle at the bottom, the length of which is less than or equal to the radius of the moisture crucible.

[0011] Furthermore, the bottom of the movable cover is provided with an anti-slip pad.

[0012] Furthermore, the cleaning brush is comb-shaped and has bristles made of tough steel wire; the length of the cleaning brush is less than or equal to the radius of the moisture crucible.

[0013] Furthermore, the drive mechanism includes a reversible DC motor and a reduction gear set.

[0014] Furthermore, the movable cover has multiple air inlets evenly distributed on its sidewall.

[0015] Furthermore, the distance between the bottom of the cleaning nozzle and the surface of the coal in the moisture crucible is approximately 3-5 mm.

[0016] Furthermore, the cleaning nozzle and cleaning brush are fixedly connected to the lifting mechanism via a fixed cover.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the moisture crucible cleaning device combines the structural design of rotating moisture crucible, boot-shaped suction nozzle and comb-shaped brush that are relatively stationary, which can maximize the coverage and cleaning of surface powder residue in the crucible, making the negative pressure suction of the discharge channel for powder removal simple and quick, and achieving efficient and high-quality cleaning of all powder residue in the moisture crucible without dead corners.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figure 1-3 The present invention provides the following technical solution:

[0027] A moisture crucible cleaning device includes a frame 3, a liftable cleaning assembly 1, and a rotating assembly 2, wherein:

[0028] The rotating assembly 2, located below the frame 3, includes a rotating platform 201 for placing the moisture crucible 4 and a drive mechanism 202 for rotating the rotating platform 201.

[0029] The liftable cleaning assembly 1 is located above the frame 3 and includes a movable cover 105, a lifting mechanism 101, a cleaning nozzle 103, and a cleaning brush 106. The movable cover 105 is used to fix the moisture crucible 4, is rotatably connected to the lifting assembly 101, and rotates with the rotation of the moisture crucible 4. The cleaning nozzle 103 and the cleaning brush 106 are located inside the movable cover 105 and are fixedly connected to the lifting mechanism 101.

[0030] In some specific embodiments, the cleaning nozzle 103 is connected to the discharge pipe 102, and the discharge pipe 102 is connected to the negative pressure mechanism. The negative pressure mechanism can be a common device capable of generating negative pressure, such as a vacuum feeder.

[0031] In some specific embodiments, the cleaning nozzle 103 is boot-shaped, with a circular screw opening at the top and a rectangular nozzle at the bottom. The length of the rectangular nozzle is less than or equal to the radius of the moisture crucible 4. The rectangular nozzles are radially distributed along the moisture crucible 4, forming a suction surface, which, together with the rotational movement of the moisture crucible 4, minimizes residual material.

[0032] In some specific embodiments, the bottom of the movable cover 105 is provided with an anti-slip pad 107, which helps to fix the moisture crucible 4.

[0033] In some specific embodiments, the cleaning brush 106 is covered with bristles made of tough steel wire, which are used to clean the residue that is difficult to be directly sucked up from the bottom of the moisture crucible 4. At the same time, together with the forward and reverse rotation of the rotating component 2, it assists the cleaning nozzle 103 in sucking up the residual powder in the moisture crucible 4.

[0034] In some specific embodiments, the drive mechanism 202 includes a reversible DC motor and a reduction gear set to ensure that the rotating platform 201 has a relatively suitable rotational speed, typically 1 r / s.

[0035] In some specific embodiments, multiple air inlets are evenly distributed on the side wall of the movable cover 105, and the distance between the bottom of the cleaning nozzle 103 and the surface of the coal in the moisture crucible 4 is about 3 to 5 mm. These design details constitute the dynamic conditions for the sample to be sucked away by negative pressure, further improving the efficiency of negative pressure suction.

[0036] During operation, the moisture crucible 4 is first placed on the rotating platform 201 manually or by a robotic arm. Then, the lifting mechanism 101 drives the lifting cleaning assembly 1 downwards, pressing the moisture crucible 4 firmly onto the rotating platform 201 via the movable cover 105. Simultaneously, the rotating assembly 2 rotates the moisture crucible 4, along with the movable cover 105, while the cleaning nozzle 103, cleaning brush 106, and fixed cover 104 remain relatively stationary. During the rotation of the moisture crucible 4, residual powder is repeatedly brushed by the stationary cleaning brush 106, then repeatedly sucked up by the cleaning nozzle 103, and finally discharged through the discharge pipe 102 by a vacuum suction machine. This device combines the rotation of the moisture crucible 4, the suction of the nozzle 103, and the brushing of the cleaning brush 106 to efficiently and effectively collect and remove residual substances inside the moisture crucible 4.

[0037] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
