Description

Technical Field

[0001] This utility model relates to the technical field of metal chromium smelting equipment, specifically a mixing device for metal chromium smelting. Background Technology

[0002] Metallic chromium is commonly used in the smelting of high-temperature alloys, resistance alloys, precision alloys, and other non-ferrous alloys. With advancements in science and technology, the role of high-quality metallic chromium is becoming increasingly important. There are many methods for producing metallic chromium, and regardless of the method used, the mixing process in the upstream stages plays a crucial role in the smelting of metallic chromium.

[0003] Chinese utility model patent CN218530801U discloses a high-efficiency mixing device for chromium smelting. The device includes a mixing unit and a feed hopper fixedly installed at the feed inlet of the mixing unit. Feed inlets are located on opposite sides of the top of the feed hopper, and each feed inlet contains a metering mechanism. The metering mechanism includes a fixed frame, a metering cylinder, a limiting component, a sealing component, and a vibrating component. The limiting component includes a limiting rod and a compression spring. The sealing component includes a fixed plate, a sealing plate, mating teeth, a gear, and a rotating rod. The vibrating component includes a housing, a transmission belt, a rotating shaft, and a cam. This utility model, through its metering mechanism, prevents spillage of powdered raw materials during manual feeding, accurately weighs the raw materials, avoids deviations in the mixing ratio, and improves the mixing efficiency of the mixing unit.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: the patent can quantitatively add raw materials into the mixing equipment through the quantitative mechanism, but the quantitative mechanism can only quantitatively measure two kinds of raw materials at a time. However, the smelting of metallic chromium requires mixing of heavy types of raw materials, and there are far more than two types. When using the patent, it is necessary to wait until all the raw materials in the two quantitative cylinders are released before the other raw materials can be measured. This operation method is very cumbersome and inconvenient. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A mixing device for chromium smelting includes a feeding tube 1 and a mixing device 2. The feeding tube 1 is made of transparent material and has several partition plates 11 arranged at equal angles around its circumference. A feeding cavity 12 is formed between two adjacent partition plates 11. Several scales are provided on the outer wall of the feeding tube 1. The top of the mixing device 2 is provided with a circular seat 21. The top of the circular seat 21 has a rotating groove that rotatably engages with the feeding tube 1. The bottom of the rotating groove has a discharge groove 211 that matches the cross-section of the feeding cavity 12. The top of the mixing device 2 is provided with a driving component 3 for driving the feeding tube 1 to rotate and a striking component 4 for assisting in striking the feeding tube 1. The circular seat 21 is located on the top of the mixing device 2, and the discharge groove 211 is connected to the mixing device 2. The driving component 3 and the striking component 4 are arranged around the circular seat 21.

[0027] This utility model employs multiple feeding chambers 12 to quantitatively load different raw materials. The feeding tube 1 is driven to rotate by the driving component 3, so that each feeding chamber 12 is sequentially connected to the discharge trough 211, and the raw materials can fall into the mixing equipment 2 in sequence, which simplifies the operation and improves the mixing efficiency of the mixing equipment.

[0028] The drive assembly 3 includes an L-shaped frame 31, a drive motor 32, a drive gear 33, and a driven gear ring 34. The L-shaped frame 31 is set on the top of the mixing device 2. The drive motor 32 is set vertically on the top of the L-shaped frame 31. The drive gear 33 is fixedly connected to the output end of the drive motor 32. The driven gear ring 34 is set on the outer wall of the feeding pipe 1 and meshes with the drive gear 33.

[0029] The drive motor 32 can drive the drive gear 33 to rotate, the drive gear 33 can drive the driven gear ring 34 to rotate, the driven gear ring 34 drives the feeding tube 1 to rotate in the rotating groove, and then the feeding chamber 12 can be connected to the discharge groove 211 in sequence.

[0030] The striking assembly 4 includes a telescopic rod 41, a support base 42, and guide blocks 43. The head end of the telescopic rod 41 is rotatably equipped with a roller 44, and the tail end of the telescopic rod 41 is equipped with a limiting plate 45. A spring 46 is sleeved on the telescopic rod 41. The support base 42 is equipped with a transverse sliding groove. Several guide blocks 43 are provided, and each guide block 43 is equipped with an arc-shaped guiding surface 47. The support base 42 is set on the top of the mixing device 2. The telescopic rod 41 is slidably set in the transverse sliding groove. The roller 44 abuts against the outer wall of the feeding pipe body 1. The two ends of the spring 46 are fixedly connected to the support base 42 and the limiting plate 45, respectively. All guide blocks 43 are set at equal angles around the circumference of the feeding pipe body 1 on the outer wall of the feeding pipe body 1, and the guide blocks 43 abut against the roller 44.

[0031] After the feeding tube 1 rotates, it can drive all the guide blocks 43 to rotate around its axis. The arc-shaped guide surface 47 on the guide block 43 can guide the roller 44 to move towards the support seat 42. The roller 44 drives the telescopic rod 41 and the limiting plate 45 to move synchronously. The spring 46 becomes stretched. After the roller 44 leaves the arc-shaped guide surface 47, the elastic force of the spring 46 can drive the telescopic rod 41 to move quickly in the opposite direction. The telescopic rod 41 drives the roller 44 to hit the outer wall of the feeding tube 1, so that the raw material will not stick to the inner wall of the feeding chamber 12.

[0032] The telescopic rod 41 has a polygonal cross-section, which allows the telescopic rod 41 to deflect unexpectedly, causing the roller 44 to fail to engage with the arc-shaped guide surface 47.

[0033] The top of the feeding tube 1 is provided with a removable sealing cap 13, which can seal the feeding tube 1 to prevent the raw material from accidentally spilling out.

[0034] The top of the sealing cover 13 is provided with a lever 14, which can improve the ease of opening the sealing cover 13.

[0035] The bottom of the mixing device 2 is equipped with four rectangular casters 22, which makes the entire mixing device 2 easy to move, thereby improving the ease of use.

[0036] Working principle: First, open the sealing cover 13, then add all raw materials into the feeding chamber 12 in sequence. The amount of raw materials added into the feeding chamber 12 can be observed through the scale. Of course, the feeding chamber 12 connected to the discharge trough 211 cannot be filled. After all the raw materials have been measured, put the sealing cover 13 back on. Then, the drive motor 32 drives the drive gear 33 to rotate. The drive gear 33 drives the driven gear ring 34 to rotate. The driven gear ring 34 drives the feeding tube 1 to rotate synchronously. The feeding chamber 12 can be connected to the discharge trough 211 in sequence. Then, all raw materials can enter the mixing equipment 2 in sequence. While the feeding tube 1 is rotating, the rollers 44 can be guided by all the guide blocks 43 to continuously knock on the feeding tube 1. Then the mixing equipment 2 can perform mixing operations on all raw materials.
