Description

Technical Field:

[0002] The present invention belongs to the technical field of water quality filtration for analyzers, and mainly relates to a waterway filtration device for an on-line analysis device. Background Art:

[0004] In recent years, with the increasing improvement of ore dressing automation technology and the attention of ore dressing companies to intelligent mines, on-line particle size analyzers and on-line grade analyzers have been widely used in the grinding and flotation processes of many domestic ore dressing plants. The on-line particle size analyzer and on-line grade analyzer can achieve all-weather uninterrupted automatic sampling and analysis, and on-line real-time monitoring of the concentration and fineness, and the pulp grade at each key node, which is convenient for timely discovering problems, timely adjusting the grinding fineness, the flotation reagent dosage, and relevant equipment parameters, can effectively guide on-site operations, stabilize product quality, and play a real-time guiding role in production. After each measurement, these two on-line analysis devices require sufficient flushing water to thoroughly clean the sampler, multiplexer, buffer tank, measurement probe, etc. of the device to ensure the accuracy of the next measurement. And a large amount of water needs to enter the ore dressing system every day in the ore dressing plant, and the demand for water is huge. Moreover, the ore dressing plant is built next to the mine. In order to save water resources and make full use of the natural resources of mountain seepage water, the water seeping out of the mountain is introduced into the reservoir, and the flushing water source of these two on-line analysis devices comes from the reservoir.

[0005] Since mine gravel, fallen leaves, sundries, and even newly hatched little frogs can flow down the pipe into the flushing water pipe of the analysis device, it often causes blockages in the flushing water pipe, flushing nozzle, and measurement probe of the instrument, affecting the normal operation of the device, and even causing serious damage to the device. All the required replacement parts need to be imported, with a long supply cycle and high cost, and the shutdown maintenance process takes a long time, seriously affecting production and increasing labor and material costs. Summary of the Invention:

[0007] In order to overcome the above deficiencies, the present invention provides a waterway filtration device for an on-line analysis device.

[0008] The technical solution adopted by the present invention to solve its technical problems:

[0009] A waterway filtration device for an on-line analysis device includes a cylinder body. An inlet and an outlet are provided on the top plate of the cylinder body. The inlet is communicated with the cylinder body. A flange cover plate is provided at the bottom of the cylinder body. An inner cylinder is provided inside the cylinder body. One end of the inner cylinder is fixed on the top plate of the cylinder body and is communicated with the outlet, and the other end is provided with an opening. A filter cylinder with an open bottom and a plurality of water permeable holes on the side and top is provided inside the inner cylinder. A first filter disc with a diameter larger than that of the inner cylinder and provided with a plurality of second through holes is provided at the open end of the inner cylinder. The open end of the filter cylinder is buckled on the first filter disc and the two are fixedly connected through a connecting component. One end of the connecting component is connected to the flange cover plate, and the other end presses the first filter disc against the open end of the inner cylinder.

[0010] The connecting component includes a screw rod, an upper bolt and a lower bolt on the screw rod for limiting the filter cartridge and the first filter disc. The lower end of the screw rod is connected to the flange cover plate. A through hole for the screw rod to pass through is provided in the middle of the top surface of the filter cartridge, and a first through hole for the screw rod to pass through is provided in the middle of the first filter disc.

[0011] A second filter disc with the same structure as the first filter disc is provided between the first filter disc and the lower bolt.

[0012] A middle bolt is welded on the screw rod and is located at the first filter disc.

[0013] A spring in a compressed state is provided between the screw rod and the flange cover plate.

[0014] The air release valve is located on the top plate of the cylinder body and is communicated with the inner cylinder.

[0015] Water pressure gauges are provided on both the water inlet and the water outlet.

Specific implementation manner:

[0027] The present invention can be more detailedly explained through the following embodiments. The purpose of disclosing the present invention is to protect all changes and improvements within the scope of the present invention. The present invention is not limited to the following embodiments;

[0028] An on-line analysis device waterway filtering device as described in combination with the attached drawings includes a cylinder body 1. A water inlet 5 and a water outlet 6 are provided on the top plate of the cylinder body 1. The water inlet 5 is communicated with the cylinder body 1 to introduce the water to be filtered into the cylinder body 1 for filtering preparation. A flange cover plate 14 is provided at the bottom of the cylinder body 1. An inner cylinder 4 is provided inside the cylinder body 1. One end of the inner cylinder 4 is fixed on the top plate of the cylinder body 1 in any known technical manner and is communicated with the water outlet 6. The other end of the inner cylinder 4 is provided with an opening; the inner cylinder 4 divides the interior of the entire cylinder body 1 into two parts. The outside of the inner cylinder 4 is the part to be filtered, and the inside of the inner cylinder 4 is the part being filtered or already filtered. Therefore, the water outlet should be communicated with the inner cylinder 4. A filter cartridge 8 with an open bottom and a plurality of water-permeable holes on the side and top is provided inside the inner cylinder 4. A first filter disc 15 with a diameter larger than that of the inner cylinder 4 and provided with a plurality of second through holes 17 is provided at the open end of the inner cylinder 4. The open end of the filter cartridge 8 is buckled on the first filter disc 15 and the two are fixedly connected through a connecting component. One end of the connecting component is connected to the flange cover plate 14, and the other end presses the first filter disc 15 against the open end of the inner cylinder 4. The connecting component has two functions. One is to fix the filter disc 15 and the filter cartridge 8 as a whole, and the other is to tightly press the first filter disc 15 against the open end of the inner cylinder 4 to prevent a gap between the first filter disc 15 and the inner cylinder 4 that allows sundries to directly enter the inner cylinder. In fact, this device has two filtering devices to achieve the filtering. The first filtering is actually achieved through the first filter disc 15. The water to be filtered will enter the filter cartridge 8 through the second through holes 17 on the first filter disc 15. The second through holes 17 block larger sundries outside. The second filtering is achieved through the filter cartridge 8. The water entering the filter cartridge 8 further passes through the through holes 20 on the filter cartridge 8 and finally flows out from the water outlet 6.

[0029] In order to further improve the filtering effect of this device, when selecting the filter cartridge 8, its diameter should be slightly smaller than that of the inner cylinder 4, so that the filter cartridge 8 can be easily installed into the inner cylinder 4 during installation. In this way, the gap between the filter cartridge 8 and the inner cylinder 4 will not be too large. If the diameters of the two differ greatly and the gap is large, part of the water entering from the first filter disc 15 will directly enter the inner cylinder 4, and thus will directly flow out from the water outlet 6 without passing through the second filtering of the filter cartridge 8, resulting in poor filtering effect.

[0030] The aperture of the water-permeable holes on the filter cartridge 8 is smaller than the aperture of the second through-holes 17 on the first filter disc 15, so that the sundries not filtered in the first-stage filtration can be filtered out during the second-stage filtration.

[0031] The connecting assembly includes a screw rod 9, an upper bolt 10 and a lower bolt 12 on the screw rod 9 for limiting the filter cartridge 8 and the first filter disc 15. The lower end of the screw rod 9 is connected to the flange cover plate 14, and the flange cover plate 14 supports the screw rod 9, thereby enabling the first filter disc 15 to tightly abut against the open end of the inner cylinder 4. A through-hole 20 for the screw rod 9 to pass through is provided in the middle of the top surface of the filter cartridge 8, and a first through-hole 18 for the screw rod 9 to pass through is provided in the middle of the first filter disc 15.

[0032] According to the amount and size of impurities in the water to be filtered, a second filter disc 16 having the same structure as the first filter disc 15 is further provided between the first filter disc 15 and the lower bolt 12. The lower bolt 12 is used to fix the first filter disc 15 and the second filter disc 16. At the same time, according to the water source situation, the lower bolt 12 can be adjusted, and then the first filter disc 15 and the second filter disc 16 can be rotated relative to each other. Then, the apertures of the second through-holes 17 on the filter discs 15 and 16 will be blocked from each other, that is, the aperture of the second through-hole 17 will become smaller, which is suitable for filtering water sources with fine impurities.

[0033] In order to quickly assemble the filter cartridge 8 and the first filter disc 15 and / or the second filter disc 16 during installation, save the adjustment time, and enable the first filter disc 15 to tightly abut against the open end of the inner cylinder 4, a middle bolt 11 is welded on the screw rod 9. The middle bolt 11 is located at the first filter disc 15, so that the position of the first filter disc 15 is limited. During installation, the first filter disc 15 abuts against the middle bolt 11, and the filter cartridge 8 is buckled on the first filter disc 15. At this time, the lower bolt 12 is tightened, or the lower bolt 12 is tightened after installing the second green disc 16. After the lower bolt 12 is tightened, the upper bolt 10 is tightened, and the entire filtration core is assembled.

[0034] A spring 13 in a compressed state is provided between the screw rod 9 and the flange cover plate 14. The spring 13 in a compressed state provides a certain tolerance rate for installing the filtration core. Since the length of the screw rod 9 and the welding of the middle bolt 11 need to be measured in advance to determine, errors are inevitable. At the same time, the compressed spring 13 gives an upward force to the screw rod 9, pressing the first filter disc 15 against the open end of the inner cylinder 4.

[0035] In order to avoid air in the inner cylinder 4, a vent valve 7 is provided. The vent valve 7 is located on the top plate of the cylinder body 1 and is communicated with the inner cylinder 4.

[0036] This filtering device is detachable. After filtering for a period of time, it needs to be disassembled for cleaning. However, how can we know that the device needs to be cleaned? Then, pressure gauges 19 are provided at both the water inlet 5 and the water outlet 6 to make a judgment. According to the difference between the two pressure gauges 19, it is possible to roughly determine whether cleaning is required.

[0037] Furthermore, the cylinder body 1 includes an upper cylinder 2 and a lower cylinder 3. The diameter of the upper cylinder 2 is larger than that of the lower cylinder 3, and the diameter of the lower cylinder 3 is larger than that of the inner cylinder 4. As Figure 1 shown, the water source entering from the water inlet 5 falls on the connecting table surface of the upper cylinder 2 and the lower cylinder 3, and does not directly impact on the flange cover plate 14. In fact, this is a protection for the flange cover plate 14. In addition, after the water flow impacts the table surface, the water flow direction is towards the central axis of the upper cylinder 2. At this time, the lower surface of the first filter disc 15 or the second filter disc 16 will be washed, reducing the probability of blockage of the filter discs 15 or 16.

[0038] The parts not described in detail above are prior arts, so no detailed description is given.
