Description

Technical Field

[0001] The utility model relates to the technical field of bulk material mixing, and more specifically, to a bulk material mixing device. Background Art

[0002] Loose materials refer to a large amount of granular and powdered materials piled together, such as coal, sand, grains, cement and sugar cubes. Take gold-loaded carbon as an example. Gold-loaded carbon is a material used in the gold smelting process to absorb gold from the ore pulp. Gold-loaded carbon often appears in a loose state close to dust. When testing gold-loaded carbon, the incoming gold-loaded carbon needs to be mixed first. At present, the gold-loaded carbon mixture is often mixed manually by the cone stacking method, and then sampled and bagged. However, this operation method is inefficient, has high labor costs and is not conducive to the health of operators.

[0003] Chinese patent CN206095757U discloses a mixing device for gold-loaded carbon gold analysis standard material, the device includes a support frame and a mixing tank, a material storage box is installed on the support frame, a central tube coaxial with the center of the mixing tank is installed at the bottom of the material storage box, a discharge pipe is installed at the lower end of the central tube, a rotating plate is sleeved on the central tube, a rotating mechanism for driving it to rotate relative to the central tube is provided on the rotating plate, a rotating tube is rotatably installed on the rotating plate, a mixing assembly is provided on the rotating tube, and a lifting mechanism for driving the mixing assembly to vertically reciprocate and lift is provided on the rotating plate. When preparing gold-loaded carbon gold analysis standard material, the device can be used to complete adsorption and mixing operations in sequence, which is beneficial to improve the mixing uniformity of the gold-loaded carbon. However, this scheme has a defect that it stirs the gold-loaded carbon by means of a rotating plate. When the gold-loaded carbon is not humid enough, a stirring blind spot is likely to appear in the area where the rotating plate does not pass, so it is only suitable for mixing loose materials such as gold-loaded carbon with high humidity. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a bulk material mixing device which can evenly mix dry or wet bulk materials.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A loose material mixing device is provided, which is provided with a mixing part, wherein the mixing part comprises a frame, a rotating rod and two mixing discs, wherein the middle part of the rotating rod is rotatably connected to the frame, and the mixing discs are rotatably connected to both ends of the rotating rod respectively, and a discharge mechanism that can be controlled to open and close is provided at the bottom of the mixing disc, and the mixing disc maintains a horizontal posture during the rotation of the rotating rod.

[0007] With this arrangement, workers first load the loose materials onto one of the mixing pans, rotate the rotating rod to place the loaded mixing pan directly above the empty mixing pan, open the discharge mechanism of the upper mixing pan, and the loose materials fall into the mixing pan below through the discharge mechanism under the action of gravity, completing a cone stacking; then the rotating rod rotates again, and the above cone stacking operation is repeated several times until the loose materials reach the preset mixing degree. This cone stacking mixing method is applicable to both dry loose materials and wet loose materials, and increases the scope of application of loose material mixing devices.

[0008] Preferably, the bottom of the mixing tray is a funnel structure, and the discharge mechanism is located in the middle of the bottom of the mixing tray.

[0009] With this arrangement, the bottom of the mixing plate with a funnel structure is more conducive to the loose materials sliding down to the discharge mechanism, which is conducive to reducing the residue of loose materials in each cone stacking process and improving the mixing efficiency.

[0010] Preferably, the discharge mechanism includes a solenoid valve, a discharge nozzle and a blocking piece, the discharge nozzle is fixedly installed at the bottom of the mixing plate, the blocking piece is movably inserted into the discharge nozzle, the solenoid valve is arranged on the outside of the discharge nozzle and connected to the blocking piece, and the solenoid valve is used to control the blocking piece to be inserted into or removed from the discharge nozzle.

[0011] With this arrangement, when material discharge is required, the solenoid valve contracts, pulling the blocking piece outward, and the loose and broken materials lose the restriction of the blocking piece and fall from the discharge nozzle; when the material discharge is completed, the solenoid valve resets, and the blocking piece is inserted into the discharge nozzle to complete the closure of the discharge nozzle.

[0012] Preferably, it further comprises a dustproof cabinet, the mixing part is arranged in the dustproof cabinet, a loading port is provided on the top of the dustproof cabinet, and a unloading port is provided on the side of the dustproof cabinet.

[0013] When dry bulk materials are mixed, a large amount of dust is often generated. Through this setting, the dustproof cabinet can avoid air pollution caused by dust, limit the scope of dust from the bulk materials, facilitate its recovery, and reduce the loss during the mixing process of the bulk materials.

[0014] Preferably, a loading plate is provided on the outer side of the loading port, and a unloading plate is provided on the outer side of the unloading port, and both the loading plate and the unloading plate are slidably connected to the dustproof cabinet.

[0016] Preferably, it also includes a material discharge part, which includes a material discharge guide rail, a movable plate and a material discharge barrel. The movable plate is slidably connected to the material discharge guide rail, and the material discharge barrel is detachably connected to the movable plate. The material discharge guide rail is laid at the bottom of the mixing part and is arranged through the material discharge port.

[0017] With this arrangement, after the mixing work is completed, the movable plate works to send the discharge barrel along the discharge guide rail to the bottom of the mixing section, the rotating rod works to make the mixing plate carrying the loose materials hover above the discharge barrel, and the discharge mechanism opens to allow the loose materials to fall into the discharge barrel; after the discharge barrel completes loading, the discharge mechanism closes, the movable plate works to move along the discharge guide rail, and sends the discharge barrel to the outside of the dustproof cabinet, and the worker can directly move the discharge barrel away to complete the discharge.

[0018] Preferably, a weighing mechanism is also provided on the movable plate, and the weighing mechanism is used to measure the mass of the goods loaded in the lower barrel.

[0019] With this setting, when performing unloading operations, the unloading portion can be accurately determined each time. When the bulk material loaded in the unloading barrel reaches the specified weight, the unloading operation is completed, which is convenient for subsequent quantitative packaging of the bulk material without the need for repackaging.

[0020] Preferably, it further comprises a sampling part, which comprises a sampling tube and a sample divider, the sample divider is passed through the dustproof cabinet and fixedly connected to the dustproof cabinet, and the sampling tube is movably connected to the sample divider.

[0021] With this arrangement, after the bulk material is mixed, the sampling tube can be rotated to the mixing plate or the discharge barrel to absorb the bulk material sample, and the bulk material sample is transported to the sample divider. The sample divider divides the bulk material sample into several portions according to preset conditions, and transports it outside the dustproof cabinet for the operator to take samples.

[0022] Preferably, the sampling portion is arranged beside the mixing portion, and the sampling tube is provided with an opening arranged upward.

[0023] With this arrangement, when the material is discharged, the sampling tube can be rotated between the mixing disk and the discharge barrel to receive the falling loose materials. The loose materials enter the sampler directly along the sampling tube under the action of gravity, without the need to install a fan for forming negative pressure suction, which is conducive to simplifying the equipment and saving costs.

[0024] Preferably, it also includes a magnetic sieve plate, which is installed below the loading port and movably connected to the dustproof cabinet.

[0025] With this arrangement, when loading, the magnetic sieve plate rotates to between the loading port and the mixing disk, the loaded loose materials are first filtered through the magnetic sieve plate, and the magnetic metal particles contained in the loose materials are adsorbed by the magnetic sieve plate and filtered out, which helps to reduce impurities in the loose materials.
