Description

Technical Field

[0001] The utility model relates to a mixer, in particular to a mixer for mixing water with a sample of easily fluidized goods, and belongs to the technical field of production and manufacturing of laboratory testing devices. Background Art

[0002] The so-called liquefiable cargo refers to bulk solid cargo that contains some fine particles and a certain amount of moisture, and will form fluidization if the moisture content exceeds its transportable moisture limit during transportation.

[0003] Transportable moisture limit (TML) refers to the maximum moisture content of fluidizable solid bulk cargoes for safe transportation. In layman's terms, it is the maximum moisture percentage of fluidizable solid cargoes that will not fluidize during transportation.

[0004] During the transportation of goods that are easy to liquefy, the moisture content of the goods must be controlled below the transportable moisture limit of the goods to ensure their safe transportation on ordinary bulk ships that do not have special protection measures for goods that are easy to liquefy. For example, for coal or iron ore, when the actual measured moisture content is below its transportable moisture limit, it means that the batch of goods is not easy to liquefy and is suitable for transportation on ordinary bulk ships. Otherwise, it means that the batch of goods is easy to liquefy, which will bring certain risks to ordinary bulk ships during its transportation. Special protection or the use of special ships that can adapt to the transportation of easy to liquefy goods is required.

[0005] Different substances have different transportable moisture limits. There are usually three methods for testing the transportable moisture limit, namely the flow plate method, the insertion method and the Porter / Fan method. Among them, the determination of the transportable moisture limit of goods that are easy to liquefy using the flow plate method or the insertion method usually includes the steps of sampling, determining the original moisture content of the sample and determining the amount of added water. The determination of the amount of added water is to determine the total amount of water added to the sample when water is continuously added to it and mixed with it until it begins to fluidize. The sum of the added water and the original water content of the sample is the transportable moisture limit of the sample.

[0006] According to the requirements of Resolution MSC.462(101) / Appendix 21.2 / Determination of Transportable Moisture Limit / Insertion Degree Test Method of the International Maritime Solid Bulk Cargoes Code, after the sample is mixed with water, it is necessary to use a mixing container to mix the water and the sample. Since the amount of water added each time cannot be too much, the water mixing operation needs to be repeated many times. However, the document does not provide detailed and strict regulations on mixing containers and mixing operations. Therefore, different inspectors may use various containers and different mixing methods during testing. At present, the common practice is that the inspectors place the sample in a plastic basin or a stainless steel basin, and after adding water, use their hands wearing rubber gloves to manually mix the water-added sample by turning it upside down until it just begins to fluidize.

[0007] It can be seen that the existing water mixing method and process have many shortcomings, including:

[0008] The sample is in contact with the air over a large area, causing evaporation loss of sample water;

[0009] If the mixing action is too small, the mixing time of the sample will be prolonged, resulting in longer evaporation time and more evaporation. If the mixing action is too large, the sample may be thrown out of the container, causing damage to the integrity of the sample.

[0010] After the sample is mixed, some sample and water will stick to the gloves and the container wall, causing the loss of sample and water. As the surface area of ​​the container increases and the number of mixing operations increases, the amount of sample and water lost will also increase, which will have an adverse effect on the test results.

[0011] In addition, when mixing samples manually, gloves are in direct contact with samples. Samples such as coal or ore have irregular particles and often have sharp edges. Therefore, they often puncture or scratch the gloves, causing a certain amount of sample to enter the gloves, which not only destroys the integrity of the sample, but also causes damage to the hands of the tester. At the same time, the need to repeatedly add water and mix the samples will consume a lot of physical strength of the tester.

[0012] The most critical issue is that manual sample mixing is often not evenly mixed, which leads to deviations in test results. Utility Model Content

[0062] The technical solution of the present utility model is described in detail below with specific embodiments.

[0063] Example

[0064] This embodiment provides a fluidizable cargo sample water mixing machine for mixing a fluidizable cargo sample with water when the transportable moisture limit is tested by the flow disk method or the insertion method.

[0065] like Figure 1 A partial cross-sectional structural schematic diagram of a water-mixing mixer for fluidized cargo samples provided by the present utility model is shown as follows:

[0066] A water mixing machine for fluidizing cargo samples, comprising:

[0067] Operating cabinet 100, rotation system, support mechanism and mixing tank 400;

[0068] The rotating system is arranged on the operating cabinet 100, the supporting mechanism is arranged on the top plate 110 of the operating cabinet 100, the mixing tank 400 is obliquely arranged on the supporting mechanism and the bottom of the mixing tank 400 is rotatably connected to the rotating system;

[0070] From the above description, we can see that:

[0071] The water-mixing mixer for fluidized cargo samples provided in this embodiment comprises an operating cabinet, a rotating system, a supporting mechanism and a mixing tank, wherein the rotating system is arranged on the operating cabinet, the supporting mechanism is arranged on the top plate of the operating cabinet, the mixing tank is obliquely arranged on the supporting mechanism and its bottom is rotatably connected to the rotating system, the interior of the mixing tank is used to place fluidized cargo samples and mix water into the fluidized cargo samples, and the mixing tank can rotate under the drive of the rotating system, so that the fluidized cargo samples and the added water can be mixed;

[0072] Obviously, the water mixing machine for fluidized cargo samples provided by the utility model overcomes the shortcomings of the prior art. It can not only unify the operating procedures and operating specifications for sample water mixing in the transportable moisture limit detection, ensure the accuracy of the transportable moisture limit measurement results using the flow disk method or the insertion method, but also reduce the labor intensity of the detection personnel and ensure the safety of the detection personnel.

[0073] Further, from Figure 1 You can also see:

[0074] The operating cabinet 100 is provided with a frame-type support frame 120 inside, and the frame-type support frame 120 is used to install and support the rotating system, so that the overall appearance structure of the fluidized cargo sample water mixing mixer provided in this embodiment can be simple and beautiful.

[0075] Further, from Figure 1 You can also see:

[0076] The rotation system includes a motor 210, a reduction box 220 and a transmission component 230, wherein the motor 210 and the reduction box 220 are respectively mounted on a support frame 120 and the motor 210 is connected to the shaft of the reduction box 220, and the transmission component 230 is arranged on the top plate 110 of the operating cabinet 100 and its two ends are respectively rotatably connected to the reduction box 220 and the bottom of the mixing tank 400.

[0077] Similar to the design of the operating cabinet structure, the rotation system is arranged in this way, so that the overall appearance structure of the fluidized cargo sample water mixing mixer provided in this embodiment can be simple and beautiful.

[0078] Optionally, the water-mixing mixer for fluidized cargo samples provided in this embodiment has:

[0079] The transmission member 230 may be a universal joint transmission shaft, one end of which is connected to the shaft of the reduction box 220, and the other end of which is frictionally connected to the bottom of the mixing tank 400; or

[0080] The transmission member 230 may be a gear transmission mechanism, one end of which is connected to the shaft of the reduction box 220 , and the other end of which is rotationally connected to the bottom of the mixing tank 400 through gear meshing.

[0081] Obviously, this can provide users with more choices.

[0082] Further, from Figure 1 It can also be seen that in the water-mixing mixer for fluidized cargo samples provided in this embodiment:

[0083] The supporting mechanism includes a front support 310, a supporting diagonal rod 320, and a rear support 330;

[0084] The front end of the supporting diagonal rod 320 is placed on the front bracket 310, and the rear end is placed on the top plate 110 of the operating cabinet 100, in an inclined state with the front end higher than the rear end, and a plurality of bearings 340 are also provided on the supporting diagonal rod 320;

[0085] The rear bracket 330 is disposed behind the front bracket 310 and is used to support one end of the transmission member 230 connected to the mixing tank 400;

[0086] The mixing tank 400 is obliquely disposed between the front bracket 310 and the rear bracket 330 , and the outer wall of the tank body of the mixing tank 400 is rotatably connected to the outer edges of the bearings 340 , and the bottom of the mixing tank 400 is rotatably connected to the rotating system.

[0087] It can be seen that such a design enables the mixing tank to be simply and conveniently removed from or put back on the supporting mechanism and to be rotationally connected to the transmission member again, making the mixing operation simple, quick and convenient.

[0088] Further, such as Figure 2 The half-section structure schematic diagram of the mixing tank of a water mixing machine for fluidizing cargo samples provided by the utility model is shown in this embodiment:

[0089] The tank body 411 of the mixing tank 400 is a cylindrical component, and the tank bottom 412 is an arc-shaped component, and the tank bottom 412 is smoothly connected to the tank body 411 in an arc shape. The tank bottom 412 is also provided with a connecting piece 420 rotatably connected to the rotating system. The opening of the mixing tank 400 is provided with a tank cover 430, and the inner wall of the tank body is also provided with stirring blades 440 extending from the bottom of the mixing tank 400 to the opening of the tank body.

[0090] Obviously, the mixer provided in this embodiment can efficiently mix the sample and the added water in the mixing tank through its stirring blades to obtain a uniformly mixed sample. Moreover, since the internal structure of the tank is simple and smooth, the sample is not easy to stick to it, thereby ensuring the integrity of the sample and being easy to rinse and maintain.

[0091] Further, from Figure 1 and Figure 2 In the , you can see:

[0092] A hoop 413 or a ring track 414 corresponding to the outer edge of each bearing 340 is also provided on the outer wall of the tank body 411. Each hoop 413 or ring track 414 is frictionally and rotationally connected with the outer edge of the corresponding bearing 340.

[0093] The hoop or ring rail can not only improve the structural strength of the tank body, but also serve as a guide rail to better connect with the bearing for rotation.

[0094] Further, from Figure 1 and Figure 2 You can also see:

[0095] The tank cover 430 and the tank body 411 are also provided with a locking mechanism 450 that cooperates with each other to lock, and the tank cover 430 is also provided with a carrying handle 431 .

[0096] The locking mechanism can ensure that the tank cover is well connected and fixed to the tank body, so that the tank cover will not fall off during the rotation of the mixing tank. Moreover, the tank cover can better seal the mixing tank, thereby locking the sample and its moisture in the mixing tank.

[0097] Further, from Figure 1 It can also be seen that the water-mixing mixer for fluidized cargo samples provided in this embodiment also includes a controller;

[0098] The main body of the controller (not shown in the figure) is arranged inside the operating cabinet 100, and is used to control the start and stop of the rotating system and the adjustment of its rotating speed and running time. The control panel 510 of the controller is arranged on the panel outside the operating cabinet 100.

[0099] Through such an expanded technical solution, the water mixing machine for fluidized cargo samples provided in this embodiment can be automatically controlled by a controller. If functions such as timing are further set, different automatic mixing schemes can be formulated according to the mixing requirements of different samples, thereby providing users with more diverse choices.

[0100] Further, from Figure 1It can also be seen that the fluidizable cargo sample water mixing mixer provided in this embodiment also includes a lockable universal wheel 130, which is arranged at the bottom of the operating cabinet 100 and is used to move the operating cabinet 100, thereby making it more convenient to move and use.

[0101] From the above description, we can see that:

[0102] The utility model constructs a fluidized cargo sample water mixing mixer capable of mixing fluidized cargo samples with added water by operating a cabinet, a rotating system, a supporting mechanism and a mixing tank, and meets the purpose of mixing fluidized cargo samples with added water when using a flow disk method or an insertion method for transportable moisture limit detection, namely:

[0103] As long as the sample is loaded into the mixing tank of the mixer provided by the utility model, and the mixing tank is placed on the supporting mechanism and then closed, the mixing tank can be driven to rotate by the rotating system to automatically mix the sample after adding water;

[0104] Because the mixing tank of the mixer provided by the utility model has a tank cover, the mixing tank can be sealed, so that the original water content of the sample in the tank and the added water will not evaporate and lose, and the sample will not be thrown out during the mixing process, so the integrity of the sample can be guaranteed;

[0105] Since the mixer provided by the utility model can roll and mix by itself without manual participation, it can avoid the unevenness of manual mixing and the loss of water and sample volume, and also avoid the damage that may be caused to the mixing personnel by manual mixing, and can save the physical strength of the mixing personnel;

[0106] In addition, the technical solution provided by the utility model can be easily expanded. For example, it can be automatically controlled by adding a controller, thereby providing users with more choices. The tank body and the tank bottom of the mixing tank are respectively a cylinder and an arc-shaped component and are smoothly connected in an arc shape. A stirring blade is also provided in the tank body, so that not only the mixing can be more uniform, but also the integrity of the sample can be ensured because the inside of the tank body is simple and smooth, and it is not easy to stick to the sample, and the use and cleaning are convenient, and the maintenance is easy;

[0107] In summary, the technical solution provided by the utility model overcomes the shortcomings of the existing technology, has substantial characteristics and can achieve obvious progress compared with the existing technology, and therefore has great promotion and application value.
