Description

Technical Field

[0001] The present application relates to the technical field of sampling tools, and in particular to a quartering reduction sampling device for incineration fly ash. Background Art

[0002] At present, in the process of sampling and preparing industrial solid waste, if the number of samples collected is too large, it is necessary to reduce the samples to obtain samples that meet the requirements. At present, the quartering method is often used for reduction sampling. The quartering method for reduction sampling in the related art generally refers to mixing the samples and piling them into squares of equal thickness, then dividing the square-shaped samples diagonally into four opposite triangles, and taking two of the opposite triangle samples and mixing them to achieve the purpose of reduction sampling.

[0003] Waste incineration fly ash refers to the residues collected in the flue gas purification system and heat recovery system after waste incineration, which generally accounts for 3%-5% of the total waste incineration. It is classified as hazardous waste in my country. Analysis shows that waste incineration fly ash is not a chemically inert substance, and it contains heavy metals that are most harmful to the human body: lead, chromium, mercury, arsenic, and cadmium.

[0004] With respect to the above-mentioned related technologies, the inventors believe that: untreated waste incineration fly ash has a low moisture content and is loose, and is easily blown up when exposed to the outside world. In addition, the fly ash itself is a hazardous waste. During the quartering process of the incineration fly ash, the required mixing, pressing, and sample splitting processes will disturb the fly ash. The operating environment is very bad due to the blown fly ash, which endangers the occupational safety and health of the operators. Utility Model Content

[0005] The purpose of the present application is to provide a quartering reduction sampling device for incineration fly ash, so as to solve the problem that in the process of quartering the incineration fly ash, the required mixing, pressing, and splitting of samples will disturb the fly ash, and the operating environment will become very bad due to the raised fly ash, which endangers the occupational safety and health of operators.

[0008] Furthermore, the diagonal dividing component includes two diagonal dividing edges arranged at the bottom of the pressing plate, the two diagonal dividing edges are arranged to cross each other, and two diagonal tracks are arranged on the surface of the quarter-plate, the two diagonal tracks are arranged to cross each other, and the two diagonal tracks are respectively matched with the two diagonal dividing edges.

[0009] Furthermore, the two diagonal dividing edges are respectively located on the two diagonal lines at the bottom of the pressing plate, and the two diagonal tracks are respectively located on the two diagonal lines on the surface of the four-divided plate.

[0010] Furthermore, the dust suction component comprises a dust collector arranged outside the quarter-plate, and the dust suction end of the dust collector is provided with a flat-mouthed fine mouth matching with the flat-mouthed fine groove.

[0018] The following is combined with Figure 1-2 This application is described in further detail.

[0019] The present application embodiment discloses a four-division sampling device for incineration fly ash, referring to Figure 1 In this embodiment, the quartering sampling device includes a quartering plate 1, an isolation frame 2, a sample pressing plate 3, a diagonal dividing assembly, a flat sample slot 11, and a dust collecting assembly. The quartering plate 1 is composed of a bottom plate and four side plates; the bottom plate is placed on a designated table or ground, and the four side plates are fixedly mounted on the top of the bottom plate to enclose the top of the bottom plate.

[0020] At the same time, the isolation frame 2 is surrounded by four side panels, and the top and bottom of the isolation frame 2 are interconnected, and the bottom of the isolation frame 2 is fixedly installed on the top of the four-part plate 1, so that the isolation frame 2 and the four-part plate 1 are combined with each other to form a box with an opening on the top, so as to facilitate the storage of incineration fly ash, thereby reducing the lifting and diffusion of incineration fly ash when the incineration fly ash is subsequently sampled.

[0021] Preferably, the isolation frame 2 is made of transparent glass; when sampling the incineration fly ash, the transparent glass allows the operator to clearly observe the conditions inside the isolation frame 2 and the quarter panel 1, thereby reducing the lifting and diffusion of the incineration fly ash.

[0022] In addition, refer to Figure 1 and Figure 2 In the present embodiment, the pressing plate 3 is movably installed inside the isolation frame 2, and the pressing plate 3 cooperates with the quarter plate 1; when the pressing plate 3 cooperates with the quarter plate 1 to compact the fly ash sample, the setting of the isolation frame 2 will not cause the fly ash to be lifted up due to disturbance and reduces the contact with the operator.

[0023] At the same time, a diagonal dividing assembly is also provided between the pressing plate 3 and the quartering plate 1, and the diagonal dividing assembly is used to divide the incineration fly ash stored in the quartering plate 1 into four equal parts. Specifically, the diagonal dividing assembly includes a diagonal dividing edge 31 and a diagonal track 12. Among them, there are two diagonal dividing edges 31, and the two diagonal dividing edges 31 are respectively installed at the bottom of the pressing plate 3. More specifically, the two diagonal dividing edges 31 are respectively located on the two diagonals at the bottom of the pressing plate 3, and the two diagonal dividing edges 31 are arranged to cross each other.

[0024] Two diagonal tracks 12 are provided, and the two diagonal tracks 12 are respectively installed on the top surface of the quarter-board 1. More specifically, the two diagonal tracks 12 are respectively located on two diagonals on the surface of the quarter-board 1, and the two diagonal tracks 12 are arranged to cross each other. At the same time, the two diagonal tracks 12 are respectively matched with the two diagonal dividing edges 31.

[0025] When the mixed fly ash sample is placed into the quarter-plate 1, the pressing plate 3 slides down along the isolation frame 2 so that the pressing plate 3 cooperates with the quarter-plate 1 to compact the fly ash sample, so that the diagonal dividing edges 31 cooperate with the diagonal tracks 12 to divide the fly ash sample into four opposite triangles, and the four opposite triangles are individually isolated, so that the fly ash sample can be divided into four equal parts.

[0026] Better, refer to Figure 1 and Figure 2 In the present embodiment, a movable handle 32 is fixedly installed on one side of the bottom of the pressing plate 3, and a movable groove 21 is opened on one side of the isolation frame 2. The movable groove 21 cooperates with the movable handle 32, so that the operator can use the movable handle 32 to move the pressing plate 3 down or up in the isolation frame 2 along the movable groove 21, thereby facilitating the pressing plate 3 to compact the fly ash sample and facilitating the separation of the pressing plate 3 from the outside of the isolation frame 2.

[0027] In addition, refer to Figure 2 In this embodiment, two flat-mouthed fine sample grooves 11 are provided, and the two flat-mouthed fine sample grooves 11 are respectively opened on the two side walls of the quarter plate 1, and the two flat-mouthed fine sample grooves 11 are respectively connected with the two opposite triangles. At the same time, the two flat-mouthed fine sample grooves 11 are sealed with flat-mouthed plugs 5, and the flat-mouthed plugs 5 cooperate with the flat-mouthed fine sample grooves 11 to clamp and seal the flat-mouthed fine sample grooves 11, so as to prevent the fly ash sample from being ejected from the outside of the quarter plate 1 along the flat-mouthed fine sample grooves 11 before sampling.

[0028] The dust suction component is arranged outside the quarter plate 1, and cooperates with the flat-mouth fine sample slot 11 to successively suck the fly ash samples in the two opposite triangles, thereby completing the collection of the fly ash samples in the two opposite triangles.

[0029] Specifically, refer to Figure 1 In this embodiment, the dust collection assembly includes a dust collector 4 and a flat-mouthed fine nozzle 41. The dust collector 4 is placed outside the quarter-board 1; the flat-mouthed fine nozzle 41 is installed on the dust collection end of the dust collector 4, and the flat-mouthed fine nozzle 41 cooperates with the flat-mouthed fine groove 11 so that the flat-mouthed fine nozzle 41 can be inserted into the flat-mouthed fine groove 11.

[0030] When it is necessary to collect the fly ash samples, first remove the flat-mouth plug 5, then use the flat-mouth fine nozzle 41 to insert it into the flat-mouth fine sample slot 11, and then start the vacuum cleaner 4 to suck the two opposite triangle fly ash samples into the vacuum cleaner 4 in turn, thereby completing the collection of the two opposite triangle fly ash samples.

[0031] Therefore, by setting up the structure in which the four-dividing plate 1, the isolation frame 2, the sample pressing plate 3, the diagonal dividing component, the flat-mouth fine sample groove 11 and the dust suction component cooperate with each other, the contact between the operator and the fly ash during the mixing, pressing and splitting of the sample can be isolated to the greatest extent, and the fly ash can be controlled within the equipment, thereby not only reducing the pollution to the environment, but also reducing the harm to the occupational safety and health of the operators.

[0032] The implementation principle of the quartering reduction sampling equipment for incineration fly ash in the embodiment of the present application is as follows: when it is necessary to sample the fly ash sample, the operator first uses the flat-mouthed plug 5 to seal the flat-mouthed fine sample groove 11, and then places the mixed fly ash sample into the quartering plate 1. The operator then uses the moving handle 32 to move along the moving groove 21 to drive the pressing plate 3 to move downward in the isolation frame 2, so that the pressing plate 3 cooperates with the quartering plate 1 to compact the fly ash sample, and the diagonal dividing edges 31 on the pressing plate 3 cooperate with the diagonal tracks 12 on the quartering plate 1 to divide the fly ash sample into four opposite triangles, thereby being able to divide the fly ash sample into four equal parts.

[0033] Then remove the flat-mouth plug 5, and use the flat-mouth fine nozzle 41 on the vacuum cleaner 4 to insert it into the flat-mouth fine sample slot 11, and then start the vacuum cleaner 4 to suck the two opposite triangle fly ash samples into the vacuum cleaner 4 in turn, thereby completing the collection of the two opposite triangle fly ash samples.
