Description

  The present invention relates to a sample processing apparatus that performs various processes such as pulverization and processing in a sanitary manner.

In general, asbestos contained in building materials (asbestos products) constructed in buildings is crushed into a fine powder from a predetermined amount of sample collected from each construction site, and then dispersion dyeing analysis and X-ray diffraction are performed. The content and properties of asbestos are ascertained by analytical methods.
The sample collected at this time is pulverized by, for example, transferring the coarsely pulverized sample by a pulverizer such as a jaw crusher to a finely pulverizing device such as a sealable ball mill that finely pulverizes the sample while preventing dust scattering during pulverization. Instead, pulverization adjustment processing is performed.
In addition, as a technique for eliminating the complexity of using a plurality of crushing devices as described above, for example, a sample stored in a die using a crushing device of a stamping crushing method (stamp mill type) as shown in Patent Document 1 is used. Adjustment processing means for finely pulverizing the rice cake by the vertical movement of the basket is already known.

  As shown in FIGS. 5 and 8, the scissor cleaning part (brush dust collecting part) 31 is disposed on the outer surface of the scissors 25 and the stopper 25 b on the upper part of the rotating shaft 63 connected to the motor 62 attached and fixed to the table 3. A brush 64 that cleans in contact with the lower surface and a brush 65 that cleans the pulverized surface 25a of the basket 25 are provided, and a cylindrical dust collecting hood 66 that houses and covers both is provided.

  As shown in FIGS. 5 and 9, the scissors cleaning part (brush dust collecting part) 32 has a long brush brush 67 and a dust collecting hood at the upper part of the rotating shaft 63 connected to the motor 62 as in the scissor cleaning part 31. 69 is provided. The brush 67 can forcibly sweep dust that is not removed by air blow of the blow dust collecting portion 29 by a long brush that softly contacts the outer peripheral surface of the ridge 25.

The dust collection hoods 66 and 69 are connected to a dust collector in the same manner as the dust collection hood 57 and the dust collection hood 61, and suck the dust that detaches from the scissors 25 into the dust collection hood without being scattered outside during cleaning. It can be recovered. Further, the sample processing chamber 9 is formed in a part of the rear side wall 5 with an intake port 5a close to the table 3, and the intake port 5a is connected to a dust collector (suction device) 70 installed outside the apparatus.
With this configuration, the processing apparatus 1 collects dust in the entire sample processing chamber 9 by operating the dust collector 70 and collects the dust locally in each dust generation unit, so that the work that prevents contamination is sanitized. Can be done automatically.

  The mortar actuating part 27 and the scissor cleaning parts 29, 31, and 32 are in a lower position obtained by dividing the turning trajectory in which the scissors 25 attached and supported at both ends of the arm 36 are rotated about the rotation shaft 35 into four equal parts. It is arranged. As a result, the mortar working part 27 and the heel cleaning parts 29, 31, 32, etc. can be compactly and collectively installed around the cocoon working part 26 standing on the table 3 in the center of the adjustment processing chamber 12. The scissors 25 that have been crushed by the actuating portion 27 can be freely cleaned by selecting the scissors cleaning portions 29, 31, and 32 by forward and reverse rotation of the rotating shaft 35.

  As shown in FIG. 5, the mortar cleaning unit 33 is installed on the table 3 near the partition wall 10 on the right side of the mortar operation unit 27, and an upward brush 33a that can be freely rotated by a motor (not shown) is provided in the dust collection hood 33b. It is installed inside. The inside of the dust collection hood 33b is connected to a dust collector in the same manner as described above.

  With this configuration, the mortar 51 removed from the mortar mounting portion 54 after pulverization can be reversed and held in an inverted state, and the inside of the mortar 51 can be pressed to the brush 33a a number of times while changing the posture, and dust adhering to the inside can be removed. It can be easily cleaned by scraping and collecting dust. The mortar cleaning unit 33 can perform suction with an air blower as necessary. Accordingly, one mortar 51 can be continuously used while preventing contamination. The cleaning work of the mortar 51 is performed in a state where the pulverized sample in the mortar 51 that has been pulverized is transferred to the cup 15 taken out from the cup holder 16 and emptied. In addition, higher cleaning can be performed by providing the ultrasonic cleaning part which vibrates and wash | cleans water with an ultrasonic wave, for example instead of between the said scissors cleaning part and mortar cleaning part.

  Next, the selection unit 14 will be described with reference to FIGS. The sorting unit 14 is installed on the right side of the sample chamber 13, and includes a placing table 71 on which the cup 15 is placed, a sorting net 72 having a cup insertion space and detachably supported upward, and the sorting net 72. The vibration unit 73 is configured to support and vibrate. The vibration unit 73 can be deactivated by operating a sorting switch 74 installed in the vicinity of the sorting unit 14 in the auxiliary processing chamber 11, and the pulverized sample supplied and placed on the sorting net 72 is transferred to the vibrating unit 73. Can be screened and filtered downward.

The sorting network 72 of the embodiment for sorting the pulverized asbestos has an opening of about 500 μm. Further, the mounting table 71 can collect the surrounding dust by connecting the mesh bottom plate to the dust collector.
The sorting unit 14 can easily replace the sorting screen 72 according to the type of the object to be sorted, and can be a centrifugal sorting unit without being limited to the sieve sorting unit. Furthermore, the sorting unit 14 can filter the solution using filter paper when work such as chemical reaction processing is performed in the adjustment processing chamber 12.

  In the sieve sorting operation, the cup 15 removed from the cup holder 16 by the operator is first placed on the platform 71, and the grinding operation is performed by the hand inserted into the gloves 17 and 17 through the opening of the opened partition wall 10. The mortar 51 containing the crushed sample is taken out, and the crushed sample is inverted and supplied onto the sorting net 72. Next, when the sorting switch 74 is operated, the sorting screen 72 vibrates, and the filtered sample that has been screened by the sorting screen 72 can be accommodated in the lower cup 15.

  At this time, the non-filtered sample that remains on the sorting net 72 without being filtered is removed by inverting the sorting net 72 and transferred into the mortar 51, and the mortar 51 is set on the mortar mounting portion 54 again to perform the grinding operation again. . Then, by repeating such pulverization operation and selection operation until there is no non-filtered sample, predetermined pulverization adjustment can be completed, and subsequent analysis can be performed accurately.

  The processing apparatus 1 configured as described above is provided with an operation panel 75 on the upper side of the front side wall 4 for controlling and instructing the operation of each working unit and inputting processing conditions and the like. A control device 76 for connecting switches is installed in the lower part of the fuselage. Then, the processing apparatus 1 inputs elements for each processing condition for different specimens at each sample collection location to the operation panel 75, and operates each working unit by automatic control according to the set work sequence. The sample can be adjusted manually through the panel 75.

An emergency stop switch 77 and a changeover switch 79 for selecting each operation of the working unit are provided on the left and right sides of the start switch 24a installed on the right side below the front side wall 4. As a result, the changeover switch 79 can select in advance various operation patterns set on the operation panel 75 before the operation of the start switch 24a, that is, a pattern of sample loading / unloading operation, pulverization processing method, cleaning and additional cleaning operation. The pattern operation is operated in conjunction with the opening / closing timing of the partition wall 10 by operating the start switch 24a.
The partition wall 10 can be opened and closed independently by touch panel operation on the operation panel 75. The start switch 24a, the emergency stop switch 77, and the changeover switch 79 are preferably installed in the auxiliary processing chamber 11 in a preliminary manner.

With reference to FIGS. 6, 7, and 10, a description will be given of a process and a method for adjusting the collected sample of asbestos products by the processing apparatus 1 configured as described above.
First, in the sample insertion step 81 shown in FIG. 10, a sample container containing a sample collected from the site is inserted into the sample chamber 13 by opening the outer door 21 and the outer door 21 is closed.
Next, in the sample setting step 82, when the changeover switch 79 is operated to set the operation pattern and the start switch 24a is turned on, the operation of the indexing device 34 causes the rod 25 to turn sideways as shown in FIG. The partition wall 10 can be opened by opening the upper side of the die 51 to the setting posture of the die 51. In this state, the operator inserts his hands into the gloves 17, 17, opens the inner door 22 in the auxiliary processing chamber 11, takes out the sample container from the sample chamber 13, moves the sample in the sample container to the mortar 51 and stores it.

In the process start step 83 in which the mortar 51 containing the sample is set in the mortar mounting portion 54 of the mortar operating portion 27, when the changeover switch 79 is operated to set the processing operation and the start switch 24a is pushed and turned ON, the partition wall 10 is turned on. , The sample adjustment operation starts and the process can proceed to the pulverization process 84.
Thus, as shown in FIG. 7, the sample can be finely pulverized by the operation of the scissor operating portion 26 and the mortar operating portion 27, and the generation of dust generated at this time is suppressed, and the generated dust is prevented from being externally scattered. Processing can be performed automatically.

That is, as shown in FIG. 7A, in the mortar set state in which the mortar 51 is set on the mortar mounting portion 54, the support arm 39 of the heel actuating portion 26 faces the heel 25 on the mortar 51, and then the cylinder 59 operates and raises the dust collecting hood 57 to cover the outer periphery and the upper side of the die 51 to obtain the pulverized set state shown in FIG.
In this state, as shown in FIG. 7C, when the support arm 39 is first lowered and stopped at the crushing support position, the crushing drive unit 48 is lowered by the hydraulic operation of the elevating cylinder 47, and the tip of the driving rod 42 is moved to the flange 25. Is inserted into the engagement hole 43 and the pulverization is started.

At this time, when the support arm 39 is lowered by the operation of the cylinder 37 and stopped at the pulverization support position by stopping the air supply, the drive rod 42 pushes down the support arm 39 via the rod 25 and the holder 44 by the lowering of the pulverization drive unit 48. As shown in FIG. 7D, the sample is pressed by the flange 25. At this time, the stopper 25b of the scissors 25 can be inserted into the dust collection hood 57 to close the top of the dust collection hood 57.
In this state, the crushing drive unit 48 operates, and the sample 25 is pulverized by vertically moving (vibrating) the scissors 25 that have entered the die 51.

Note that the pressure with which the rod 25 presses the sample can be set to a predetermined pressure by adjusting the regulator of the hydraulic path of the elevating cylinder 47 and can be pushed only by its own weight of the crushing drive unit 48. Further, the vertical stroke (amplitude) of the rod 25 by the pulverization drive unit 48 is about 5 mm, and a pulverization operation can be performed by attaching a crushed drive with a desired stroke.
The pressing force, the up / down stroke, and the vibration amount are determined on the basis of data obtained by experimenting in advance for each type of sample, and an operation based on the data input to the operation panel 75 is selected and the sample is pulverized and adjusted. Can do.

  In addition, in the embodiment, the ridge 25 has a smooth surface and has a hole in the mortar 51 and a small gap of about 0.2 mm, so that the fine powder generated at the time of pulverization is suppressed by the small gap and the raised fine powder. (Dust) is blocked by the stopper 25b to restrict external scattering. Further, the air sucked during the pulverization operation prevents and collects the fine powder in the dust collection hood 57 from being scattered outside.

Therefore, even if the sample has a lot of fibers and is likely to cause dust to rise when it is pulverized, the scissors 25 move up and down at high speed while applying a predetermined pressing force within the mortar 51. Work can be efficiently pulverized in a short time.
In addition, the crushing surface 25a of the ridge 25 and the bottom of the mortar 51 are shaped so as to contact and fit in a confidential state, thereby smoothing the vertical movement that prevents the heel 25 from rolling (shaking) and uniform. Fine grinding can be performed reliably.

In such a pulverization operation, the rod operating unit 26 can appropriately select a pulverization method according to the type and situation of the sample and can easily perform pulverization combining different pulverization patterns.
That is, the die 51 can be rotated by the operation of the motor 52 along with the vertical movement of the flange 25. In this case, the sample can be uniformly pulverized while changing the pulverization position of the sample by the rotation of the die 51.

  Further, grinding and pulverizing can be performed by rotating the mortar 51 while only pressing in a state where the vertical movement of the ridge 25 is stopped. In this case, cutting and crushing can be promoted even with a sample having a large amount of fiber, by the combined action of the punch 25 in a stopped state and the rotating die 51. Therefore, for example, a treatment agent when stripping off asbestos products applied to a building is attached, and grinding and grinding work is first performed on a highly viscous or tough sample that is difficult to grind only by striking the scissors 25. After being performed, the impact crushing operation can be performed, and the fine crushing conforming to the analysis standard can be performed efficiently and easily.

  The crushing operation as described above can be automatically performed by inputting a crushing pattern into the operation panel 75 in advance based on data obtained for each type of sample. According to the processing apparatus 1 of the embodiment, in the case of a sample accommodated in the mortar 51, a pulverized sample suitable for sample analysis is obtained with a pulverization adjustment time of about 3 minutes, and the cleaning of the scissors 25 is automatically completed. be able to. If the time is insufficient, the same pulverization adjustment operation can be repeated and completed.

  In addition, when the above pulverization method requires a long pulverization time or cannot be sufficiently pulverized, or when pulverizing a sample that easily adheres to the ridge 25, for example, both sides of a round bar as shown in FIGS. By mounting the scissors 25 having a cross section or a scissors of another shape on the support arm 39, it is possible to efficiently and reliably pulverize various samples.

Next, after completing the crushing operation as described above, as shown in FIG. 7 (E), the raising of the crushing drive unit 48 and the support arm 39 lifts the rod 25 so that it can be detached from the die 51 and returned. . Further, the dust collecting hood 57 descends and stops at the original standby position by the retraction of the cylinder 59, and the series of pulverization processing ends.
After that, the process proceeds to the crushing rod cleaning operation process 85, in which the scissors 25 are selectively moved to the scissor cleaning part 29 or the scissor cleaning part 32 by the lateral rotation of the support arm 39, and the top of the mortar mounting part 54 is opened. 7 (A).

Next, the mortar 51 is removed from the mortar mounting portion 54 by the operator, and the process proceeds to the sorting process step 86. In the sorting portion 14, the above-described sieve sorting is performed, and based on the sorting result of the first pulverization sorting work, if necessary. The sample that has undergone the second pulverization selection or higher pulverization adjustment process is transferred to the cup 15 and transferred to the sample removal step 87.
In the sample removal step 87, it is desirable to close the cup 15 containing the crushed sample with a lid (not shown) prepared in the auxiliary processing chamber 11. Then, the cup 15 is opened in the sample chamber 13 by opening the inner door 22 and the inner door 22 is closed.
