Description

Technical Field

[0001] This utility model relates to the field of high-alumina bauxite detection technology, and in particular to a water-removing device for measuring bulk density. Background Technology

[0002] For refractory bricks made from high-alumina bauxite, the bulk density of the bauxite is crucial to the quality and performance of the refractory bricks. During the production process, the moisture content of the raw high-alumina bauxite is unstable, affecting the accuracy of bulk density measurement and consequently impacting product quality control. Bulk density measurement dehydration equipment can be used to dry high-alumina bauxite samples before testing. If high-alumina bauxite contains moisture, it increases the sample's mass, leading to a measured mass that is larger than the actual mass of the high-alumina bauxite. When weighing the sample using a balance, the presence of moisture will cause the balance to display a value greater than the true mass of the high-alumina bauxite in its dry state, thus affecting the accuracy of bulk density calculation. Only by removing the moisture can the accurate mass of the high-alumina bauxite be obtained, providing reliable data for subsequent bulk density calculations.

[0003] When testing the bulk density of high-alumina bauxite samples, both lumpy and powdered samples may be used. Lumpy high-alumina bauxite can better maintain the original structure and properties of high-alumina bauxite. For studying the performance of high-alumina bauxite in practical applications, such as the slag erosion resistance and high-temperature strength of refractory materials, lumpy samples are more representative. On the other hand, powdered high-alumina bauxite samples can be mixed and reacted more uniformly. For studying the basic physicochemical properties of high-alumina bauxite, such as sintering performance and the influence of mineral composition on bulk density, powdered samples are more conducive to accurate analysis.

[0004] In the dehydration process before the density determination of high-alumina bauxite samples, the tray structure of existing dehydration equipment has significant shortcomings. For high-alumina bauxite samples in different forms such as lumps and powders, traditional trays cannot achieve uniform heating of the samples, thus affecting the dehydration effect and detection accuracy. Furthermore, the high-temperature environment inside the equipment after dehydration makes sample removal inconvenient, poses a risk of burns, and easily damages the samples. Based on this, this application proposes a dehydration device for density determination, aiming to effectively solve the above problems. Utility Model Content

[0015] The tray is placed on top of the shelf. The top edge of the tray has an outer guardrail, and the top of the tray also has an inner guardrail located between the outer guardrails. The bottom of the tray, located between the inner guardrails, is made of a hollowed-out mesh.

[0016] Optionally, the support plate may also include:

[0017] The first bearing has a through-hole on the support plate, and the first bearing is fixedly installed in the through-hole.

[0018] The shaft is inserted through the inner ring wall of the first bearing;

[0019] The second gear is fixedly installed at the top of the rotating shaft, and the side wall of the second gear is meshed with the side wall of the first gear.

[0020] The second bevel gear is fixedly installed at the bottom end of the rotating shaft.

[0021] Optionally, a motor is fixedly installed on the left side of the housing, with the output end of the motor extending into the housing, and a first bevel gear that meshes with the second bevel gear is fixedly installed at the output end of the motor.

[0022] Optionally, the inner wall of the slot is provided with sliding grooves on both sides, and two semi-circular grooves are opened on both sides of the sliding block. A ball is provided in each semi-circular groove, and each ball is located in the corresponding sliding groove and can roll inside it.

[0023] Optionally, a hydraulic rod is fixedly installed on the top of the box, with the telescopic end of the hydraulic rod extending into the inside of the box. A bottom scraping component is fixedly installed on the telescopic end of the hydraulic rod, which can extend between the outer and inner barriers on the pallet and fit against the top of the pallet.

[0024] Optionally, the scraping assembly includes a top plate, two connecting rods, and a scraper. The top plate is fixedly installed on the telescopic end of the hydraulic rod. The two connecting rods are respectively fixedly connected to the two ends of the top of the top plate. The scraper is fixedly installed between the bottom ends of the two connecting rods, and the top of the scraper is set as a slope that gradually slopes downward from the middle to both sides.

[0025] Optionally, a groove is provided at the bottom of the first gear, and a second bearing is fixedly installed in the groove. The top end of the fixed shaft is fixedly inserted between the inner ring wall of the second bearing.

[0026] Optionally, the shelf includes an outer ring and a support frame. The support frame is composed of three intersecting plates. Each end of the support frame is connected to the inner wall of the outer ring, and the intersection of the support frame is fixedly mounted on the top of the first gear.

[0027] Optionally, multiple handles are arranged in a ring array on the outer side of the top perimeter of the tray, and the handles are wrapped with a heat-insulating silicone layer.

[0028] The beneficial effects of this utility model are:

[0029] When the pallet needs to be removed, the door is opened, and the fixing parts inside the door immediately move the sleeve and rotate it at a certain angle. At this time, the sleeve pulls the collar at one end of the push-pull rod, causing it to rotate around the bottom of the fixed shaft. At the same time, the sleeve, with the help of the spring, pulls the push-pull rod to produce linear displacement. Under this series of linkages, the sliding block slides along the groove on the support plate, thereby driving the shelf above the sliding block to move the pallet toward the opening of the box. In this way, the operation of taking out and putting away the pallet becomes more convenient and easier.

[0030] When the box door is closed, the sleeve and the push-pull rod work together to drive the sliding block to slide along the groove to the innermost end. At this time, the first gear and the second gear at the top of the fixed shaft mesh precisely. After the motor is started, the first bevel gear at the output end of the motor drives the second bevel gear at the bottom of the rotating shaft to rotate. Then, through the rod shaft, the second gear at the top drives the first gear to rotate synchronously. This transmission process ultimately drives the shelf and tray installed on the top of the first gear to rotate at a uniform speed. During the dehydration process, the continuous rotation of the tray allows the high-alumina bauxite sample to be heated in all directions and evenly, ensuring that the moisture is quickly and evenly dissipated, significantly improving the drying quality and efficiency.

[0031] The hydraulic rod drives the scraping component to move downwards, precisely positioning it between the outer and inner barriers of the tray, ensuring a tight fit with the top of the tray. After the tray is opened and rotated, the scraper of the scraping component continuously agitates the powdery high-alumina bauxite sample, effectively preventing uneven heating caused by sample accumulation and pushing. For lumpy high-alumina bauxite samples, they are placed in the inner barrier area of ​​the tray. The grid structure design at the bottom of the tray allows heat to penetrate in all directions, ensuring full contact with the lumpy sample and significantly improving drying and dehydration efficiency.

[0048] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0049] Please see Figures 1-8 This utility model provides a technical solution: a volume density measuring and dehydration device, including a housing 11, with an opening on the front of the housing 11, a control unit 13 on the right side of the front of the housing 11, a door 12 hinged to the opening of the housing 11, a support plate 21 fixedly installed on the inner side of the housing 11, one end of the support plate 21 extending to the opening of the housing 11, and a through slot 211 formed in the front half of the support plate 21, a sliding block 22 slidably installed in the slot 211, a vertical fixed shaft 23 inserted through the sliding block 22, a first gear 24 fixedly installed at the top of the fixed shaft 23, a collar 25 rotatably sleeved at the top of the fixed shaft 23, a push-pull rod 26 fixedly connected to the side wall of the collar 25, a sleeve 28 movably sleeved on the outside of the push-pull rod, a spring 210 fixedly connected between the inner end of the sleeve 28 and the push-pull rod 26, and a spring 210 fixedly connected between the inner end of the sleeve 28 and the push-pull rod 26. One end of tube 28 away from fixed shaft 23 is rotatably inserted with a fastener 27 fixedly connected to the inside of box door 12. A shelf 29 is fixedly installed on the top of the first gear 24. A tray 3 is set on the top of shelf 29. An outer perimeter is set at the edge of the top of tray 3. An inner perimeter is also set on the top of tray 3 between the outer perimeters. The bottom of tray 3 and the part between the inner perimeters is set as a hollow mesh. Powdered high-alumina bauxite samples are placed between the outer perimeters and the inner perimeters of tray 3, while blocky high-alumina bauxite is prevented between the inner perimeters of tray 3. The heat inside the box 11 can fully contact the surface of the blocky high-alumina bauxite samples through the mesh part at the bottom of tray 3. By classifying and placing high-alumina bauxite samples in different states, the drying and dehydration steps of powdered and blocky high-alumina bauxite samples can be carried out simultaneously, so that the high-alumina bauxite samples can be taken out later.

[0050] When the door 12 is opened, the fixing part 27 on the inside of the door 12 immediately moves and rotates the sleeve 28 by a certain angle. At this time, the sleeve 28 pulls the collar 25 at one end of the push-pull rod 26 to rotate around the bottom of the fixed shaft 23. At the same time, the sleeve 28 pulls the push-pull rod 26 to produce linear displacement with the help of the spring 210. Under this series of linkages, the sliding block 22 slides along the groove 211 on the support plate 21, thereby driving the shelf 29 above the sliding block 22 to move the tray 3 toward the opening of the box 11, which greatly simplifies the process of taking out and putting in the tray 3 and makes the operation easier and more convenient.

[0051] See Figure 3 and Figure 4 The support plate 21 has a through-hole that runs vertically through it. A first bearing 231 is fixedly installed in the through-hole. A rotating shaft 44 is inserted through the inner ring wall of the first bearing 231. A second gear 46 is fixedly installed at the top of the rotating shaft 44, and the side wall of the second gear 46 meshes with the side wall of the first gear 24. A second bevel gear 45 is fixedly installed at the bottom of the rotating shaft 44. Through the second bevel gear 45, the rotating shaft 44, and the second gear 46, the power generated by the motor 41 when it is running can be transmitted to the first gear 24, thereby realizing the rotation of the first gear 24.

[0052] See Figure 3 and Figure 4 A motor 41 is fixedly installed on the left side of the housing 11. The output end of the motor 41 extends into the housing 11, and a first bevel gear 42 that meshes with the second bevel gear 45 is fixedly installed at the output end of the motor 41. After the motor 41 is started, the first bevel gear 42 at its output end drives the second bevel gear 45 to rotate, thereby driving the second gear 46 at the top of the rotating shaft 44 to rotate, which in turn drives the first gear 24 that meshes with it to rotate, and finally drives the shelf 29 and tray 3 installed on the top of the first gear 24 to rotate at a uniform speed. The rotating tray 3 can make the sample heat more evenly, so that the moisture is evenly lost and the drying quality is improved.

[0053] See Figure 4 and Figure 5 The inner wall of the groove 211 has two sliding grooves 212 on both sides. The sliding block 22 has two semi-circular grooves on both sides. A ball bearing 221 is provided in each semi-circular groove. Each ball bearing 221 is located in the corresponding sliding groove 212 and can roll inside it. The ball bearing 221 can reduce the contact area between the sliding block 22 and the inner wall of the groove 211, thereby reducing the friction between the two. This makes the sliding block 22 move more smoothly and effortlessly in the groove 211. The ball bearing 221 can also prevent the sliding block 22 from falling out of the groove 211. With the cooperation of the ball bearing 221 and the sliding groove 212, the sliding block 22 can move horizontally in the groove 211 along the direction of the sliding groove 212.

[0054] See Figure 7 and Figure 8 A hydraulic rod 51 is fixedly installed on the top of the box 11. The telescopic end of the hydraulic rod 51 extends into the inside of the box 11, and a bottom scraping component 52 is fixedly installed on the telescopic end of the hydraulic rod 51. The bottom scraping component 52 can extend between the outer and inner barriers on the tray 3 and fit against the top of the tray 3. The position and height of the bottom scraping component 52 can be adjusted by controlling the hydraulic rod 51 to avoid the tray 3 being unable to be placed and removed smoothly due to the obstruction of the bottom scraping component 52.

[0055] See Figure 7 and Figure 8 The bottom scraping assembly 52 includes a top plate 521, two connecting rods 522, and a scraper 523. The top plate 521 is fixedly installed on the telescopic end of the hydraulic rod 51. The two connecting rods 522 are respectively fixedly connected to the two ends of the top of the top plate 521. The scraper 523 is fixedly installed between the bottom ends of the two connecting rods 522. The top of the scraper 523 is set as an inclined surface that gradually slopes downward from the middle to both sides. During the rotation of the tray 3, the two sides of the scraper 523 can scrape up the powdery high-alumina bauxite sample located between the outer and inner barriers on the tray 3, thereby turning the powdery sample over. The turned sample can be heated evenly, thereby improving the drying and dehydration efficiency of the powdery sample.

[0056] See Figure 5 The bottom of the first gear 24 has a groove 241, and the second bearing 43 is fixedly installed in the groove 241. The top end of the fixed shaft 23 is fixedly inserted between the inner ring wall of the second bearing 43. The first gear 24 is rotatably connected to the top end of the fixed shaft 23 through the second bearing 43, so that the second gear 46 can smoothly drive the first gear 24 to rotate.

[0057] See Figure 3 and Figure 6 The shelf 29 includes an outer ring and a support frame. The support frame is composed of three intersecting plates. Each end of the support frame is connected to the inner wall of the outer ring, and the intersection of the support frame is fixedly installed on the top of the first gear 24. In this way, the tray 3 placed on the shelf 29 will be constrained by the outer ring, making it difficult for it to move. The support frame allows heat to pass smoothly through the mesh part at the bottom of the tray 3 into its interior.

[0058] See Figure 2 , Figure 3 and Figure 6 Multiple handles 31 are arranged in a ring array on the outer side of the top perimeter of the tray 3, and the handles 31 are covered with a heat-insulating silicone layer. The multiple handles 31 facilitate the taking and putting away of the tray 3, and the heat-insulating silicone layer on the handles 31 can play an effective heat insulation role.

[0059] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
