Description

Technical Field

[0001] The utility model belongs to the technical field of mineral sample processing, in particular to a sample mixing device for a mineral processing laboratory. Background Art

[0002] At present, the preparation of dry ore samples in mineral processing laboratories requires manual mixing with a shovel after crushing. Generally, it takes thirteen times or more to meet the sampling standards. The whole process has high requirements on manpower. Especially when a large number of samples are required, multiple people are often required to take turns mixing the ore to ensure the uniformity of the ore sample. The whole process is time-consuming and labor-intensive. In addition, the sampling process basically involves stacking the cone first, and then sampling through the ring-picking method, quartering method, etc. The whole process requires manual operation, which leads to great errors and makes it difficult to ensure the uniformity of the sampling. Utility Model Content

[0003] The purpose of the utility model is to provide a sample mixing device for a mineral processing laboratory. By turning over, the sample in the mixer chamber is naturally dropped by gravity, and the inclined baffle causes the falling ore sample to move disorderly, thereby greatly ensuring the uniformity of the mixed sample. Moreover, the difficulty of sampling is also reduced through the cooperation of the ore discharge valve and the sampler.

[0004] In order to achieve the above objectives, the technical solution adopted by the present invention is:

[0011] Preferably, a material dividing cone column with an upper end inserted into the conical sleeve is provided in the inner center of the sampling box.

[0012] Preferably, the sampling cover is arranged on the upper part of the sampling cavity, and one end of the sampling cover is hinged to the upper cover of the sampling box, and the other end is equipped with a sampling handle.

[0013] The technical effects of the utility model are:

[0014] 1. The samples in the chamber fall naturally due to gravity by flipping, and the inclined baffle makes the falling samples move disorderly, which greatly ensures the uniformity of the mixed samples.

[0015] 2. Use motor to control mixing, and the cylindrical mixer flips and mixes instead of manual mixing with a shovel, saving time and effort, and avoiding the problem of uneven mixing caused by manual mixing.

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figure 1-2 As shown, the sample mixing equipment of the mineral processing laboratory of this embodiment includes a support frame 2 and a sample mixer 4. Two rotating shafts 3 with a phase difference of 180 degrees are fixedly installed on the sample mixer 4. A bearing is provided on the support frame 2, and the rotating shaft 3 is installed on the bearing. A motor 8 is provided on the support frame 2, and the output shaft of the motor 8 and one of the rotating shafts 3 are both sleeved with a transmission wheel 6, and the two transmission wheels 6 are matched with a transmission belt 7. The upper part of the sample mixer 4 is matched with an opening and closing cover 5, the lower part of the sample mixer 4 is connected to the ore discharge valve 9, and an inclined metal baffle 11 is welded in the sample mixer 4, and a sampler 10 is placed at the lower part of the ore discharge valve 9.

[0030] The common operation of the laboratory sample mixer is to open the opening and closing cover 5 of the cylindrical sample mixer 4, pour in the crushed and evenly distributed dry ore, close (it can be bolted or threaded) the opening and closing cover 5 to put the cylindrical sample mixer 4 in a closed state, turn on the motor 8, and then drive the rotating shaft 3 to rotate through the transmission belt 7 and the transmission wheel 6, so that the sample mixer 4 can be driven to flip. During the design, a motor 8 with adjustable speed can be selected. In this way, the flipping frequency of the sample mixer 4 can be adjusted by controlling the speed of the motor 8 to ensure that the sample in the cylindrical sample mixer 4 has sufficient time to flow from top to bottom. The internal inclined baffle can ensure that the sample moves in a disordered manner to ensure the uniformity of the sample. After the sample is mixed, open the ore valve 9 to release the mixed ore sample, and the ore sample enters the sampler 10 below under the action of gravity.

[0031] Example 2

[0032] like Figure 2 As shown, compared with Example 1, in this embodiment, the lower part of the sample mixer 4 is designed to be a downwardly convex arc or inverted cone, and a ore discharge port 12 is opened at the lowest point of the arc or inverted cone, and the ore discharge valve 9 is connected to the ore discharge port; with such a design, when discharging ore, the evenly mixed ore sample can enter the ore discharge valve 9 from the ore discharge port 12 along the lower arc or inverted cone, making the ore discharge more complete.

[0033] Example 3

[0034] The transmission wheel 6 is a sprocket or a pulley, and the corresponding transmission belt 7 is a belt or a chain. However, in actual use, sprockets and chains are used more frequently than pulleys and belts and have better stability.

[0035] Wheels 1 are installed at the lower part of the support frame 2. The wheels can be universal wheels, which can better realize the overall movement of the sample mixing equipment.

[0036] Example 4

[0037] like Figure 3-4 As shown, this embodiment discloses the specific structure of the sampler in detail. The sampler 10 includes a sampling box 15. The upper center of the sampling box 15 is connected to a conical sleeve 14. The upper part of the conical sleeve 14 is connected to an inverted cone hopper 13. The sampling box 15 is cylindrical. Partitions 16 are evenly arranged in a ring shape inside the sampling box 15. The sampling chambers are divided by the partitions. The outer side or upper side of each sampling cavity is equipped with an openable and closable sampling cover 18. The inner center of the sampling box 15 is provided with a dividing cone column 17, the upper end of which is inserted into the conical sleeve 14.

[0038] After the ore sample falls out of the ore discharge valve, it will enter the inverted cone bucket 13 and then enter the conical sleeve 14. In this way, it will fall onto the conical surface of the material distribution cone 17 and slide down along the conical surface, and then enter the various sampling cavities divided by the partition 16. After the ore is discharged, the mixed sample part can be separated from the sampler, and then the sampling cover 18 can be opened to sample the sample in the sampling cavity through tools.

[0039] Example 5

[0040] like Figure 5 As shown, in this embodiment, a sampling cover 18 is arranged at the upper part of the sampling cavity, and one end of the sampling cover 18 is hinged on the upper cover of the sampling box 15, and a sampling handle 19 is installed on the other end. The opening and closing portion of the sampling cover 18 and the upper cover of the sampling box 15 is designed to be stepped, and a small arc is provided in the stepped portion of the upper cover to avoid interference between the sampling cover 18 and the upper cover during the opening and closing process.
