Description

Technical Field

[0001] The utility model relates to the field of sodium silicate sand processing, and specifically, to a rotary drum type sodium silicate sand mixer. Background Art

[0002] A roll is a core component in rolling equipment, usually made of metal materials, having a smooth cylindrical surface and rolling grooves, and is used to guide and compress metal materials during the rolling process, and roll the metal into the required shape and size by rotating and applying pressure.

[0003] During the production process of rolls, sodium silicate sand is used, and usually a sodium silicate sand mixer is required at this time. This is a device for mixing sodium silicate sand, and its main function is to mix sodium silicate sand. Sodium silicate sand is a type of sand used in the casting industry, mainly composed of quartz sand and sodium silicate (an aqueous solution of sodium silicate) mixed in a certain proportion. Sodium silicate sand can provide relatively high strength and wear resistance, which helps to improve the quality and service life of rolls.

[0004] The main function of a sodium silicate sand mixer is to mix sodium silicate and quartz sand in a certain proportion to prepare a type of sand suitable for the casting process.

[0005] For example, Chinese Patent No. CN218855538U discloses a new type of sodium silicate sand mixer, including a base plate, a support frame, a mounting plate, a mounting opening, a cylinder body, a conical seat and an annular groove. This utility model drives two pressure wheels to roll and press the materials through two fixed rods, so that the two pressure wheels can fully roll and press the materials, enabling the materials to achieve a sufficient crushing and mixing effect.

[0006] In roll production, the mixing ratio of quartz sand and sodium silicate is an important parameter, which will affect the strength, refractoriness and cost of the sand mold. The specific mixing ratio depends on multiple factors, including the required mold strength, casting process, material and size of the roll, production efficiency and cost considerations.

[0007] However, when this utility model performs the operation of mixing sodium silicate sand, it is unable to accurately adjust the mixing ratio of sodium silicate sand. When conducting experiments and testing the mixing, using this utility model is rather cumbersome and has certain limitations; and since the crushing and mixing are carried out by pressure wheels, a layer of residue will adhere to the bottom surface of the mixing box body, which will affect the mixing effect.

[0008] Regarding the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model

[0031] According to an embodiment of the present utility model, a rotary drum type sodium silicate sand mixer is provided.

[0032] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific implementation manners, as Figures 1 - 6As shown in the figure, the rotary drum type sodium silicate sand mixer according to the embodiment of the present utility model includes a bottom plate 1. On one side of the bottom plate 1, there is a support frame 2. On the side of the support frame 2 close to the bottom plate 1, there is a quantitative component 3. On the other side of the support frame 2, there is a control panel 4. On one side of the quantitative component 3, there are several support columns 5 that cooperate with the bottom plate 1.

At the top of the quantitative component 3, there is a quartz sand storage box 10 that cooperates with the support frame 2.

[0033] With the help of the above technical solution, under the action of the sand mixing barrel 6, the rotary drum part 8 and the sand mixing component 9 of the present utility model, through the cooperation of the rotary drum shell 801, the frustum 804 and the pressing wheel 905, the quartz sand and the sodium silicate can be evenly crushed and mixed, ensuring the stability of the quality of the sodium silicate sand and helping to improve the quality and service life of the roll production; under the action of the quantitative component 3, when conducting experiments and tests on mixing, the ratio between the quartz sand and the sodium silicate can be adjusted more conveniently, thereby improving the efficiency of improving the sodium silicate sand and the stability of the quality of the sodium silicate sand; under the action of the cleaning part 907, when crushing and mixing the sodium silicate sand, the residues attached to the inner bottom end of the outer shell of the sand mixing barrel and the outer shell of the rotary drum can be continuously cleaned, further improving the effect of crushing and mixing and the quality of the sodium silicate sand.

[0034] In one embodiment, for the above-mentioned quantitative component 3, the quantitative component 3 includes an L-shaped support plate one 301 arranged on one side of the support frame 2.

[0035] The working principle of the metering component 3 is as follows: Through the control panel 4, the electric push rod 303 is controlled and started. Under the elongation action of the output shaft of the electric push rod 303, the L-shaped moving plate 304 is driven to move horizontally away from the electric push rod 303 along the first limiting groove 302. Under the movement of the L-shaped moving plate 304, the hollow cylindrical barrel 305 is driven to move.

Under the movement of the L-shaped moving plate 304, the hollow cylindrical barrel 305 is driven to move. Under the movement of the hollow cylindrical barrel 305, the first sealing cover 306 is driven to move, so that the first sealing cover 306 contacts the second L-shaped support plate 307. Under the contact of the first sealing cover 306 and the second L-shaped support plate 307, the first sealing cover 306 contacts the bottom end of the hollow cylindrical barrel 305. Then, the quartz sand in the storage box 10 enters into the hollow cylindrical barrel 305.

A conical frustum 804 matching the sand mixing assembly 9 is provided at the inner bottom end of the rotary cylinder housing 801; thereby, the quality of the sand mixing operation can be improved.

[0040] It should be explained that the conical frustum 804 mainly functions to accelerate mixing, break, guide, press, prevent sedimentation, and improve mixing uniformity. By promoting the mixing of sodium silicate and quartz sand, breaking larger sand grains, guiding the movement of materials, applying pressure to improve the density of quartz sand, preventing the sedimentation of quartz sand, and improving the uniformity of the mixture, this is the prior art and will not be explained in detail here.

Then, the bucket cover 7 is fixed to the top end of the sand mixing barrel 6. Then, according to requirements, through the control panel 4, the electric push rod 303 in the metering component 3 is controlled and started. Under the elongation of the output shaft of the electric push rod 303, the quartz sand in the hollow cylindrical barrel 305 falls into the sand mixing barrel 6 from the feed port 702 in the bucket cover 7.

[0046] At this time, through the control panel 4, the motor 803 in the rotating cylinder member 8 is controlled and started. Under the rotation of the output shaft of the motor 803, the rotating cylinder housing 801 is driven to rotate clockwise. Under the rotation of the rotating cylinder housing 801, the conical frustum 804 is driven to rotate. At the same time, through the control panel 4, the motor 901 in the sand mixing component 9 is controlled and started. Under the rotation of the output shaft of the motor 901, the rotating rod 902 is driven to rotate counterclockwise. Under the rotation of the rotating rod 902, the pressing wheel 905 is driven to roll and mix the quartz sand and water glass, and at the same time, the scraping plate 906 is driven to clean the inner side of the rotating cylinder housing 801 in the rotating cylinder member 8, avoiding residues adhering to the inner side of the rotating cylinder housing.

[0047] After the sand mixing operation is completed, all components can be closed first, and then the handle 605 in the sand mixing barrel 6 is held by hand and rotated counterclockwise. Under the action of rotating the handle 605 counterclockwise, the limiting plate 604 rotates along the limiting groove 603. At this time, all components are opened again, and the processed sodium silicate sand can be discharged from the discharge port 602.
