Abstract

PURPOSE:To permit long-period use, and the measurement of the temp. and gaseous component in an optional position as needed by operating a boring device and moving a boring means in the axial direction while rotating the same in the peripheral direction. CONSTITUTION:A pressure oil is supplied from a fluid pressure device to a cylinder 8 to raise the boring tool 2 in the stage of measuring the temp. and gaseous component in a storage part 7. At the same time, a driving device 12 is driven to rotate a revolving bar 9. The boring means 2 splined to the bar 9 is thereby rotated and is raised in this state so as to advance into the storage material 7 while boring the material 7. The temp. and gaseous component in the optional direction in the height direction of the material 7 detected by a sensor 4 are recognized by a display device 5. The operation of the fluid pressure device is stopped and the oil pressure is decreased to zero in the case of bringing down the boring means 2. The device 12 is then run backward and the boring means is lowered by the force in the descending direction generated by the rotation of the screw part 24.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for measuring the temperature and gas components of stored materials in a silo for storing lumps, granules, powder, etc.

[Conventional technology]

Generally, the temperature of items stored in silos is rarely measured, but when stored for a long period of time, the temperature may increase due to oxidation. An example of this is seen in coal, etc., which may ignite due to rising temperature. For this reason, it is necessary to check the temperature and gas state of the stored material from the outside, learn the tendency of temperature rise every 1 ton, and take appropriate measures.

Conventionally, as this type of technology, a method as shown in FIG. 4 has been generally used.

In the figure, a is a silo, and b is its storage. C is an iron wire, which is suspended from the ceiling beam d of the silo a. e indicates a temperature sensor provided on wire C. Note that a display device such as a meter connected to this temperature sensor e is not shown.

Conventionally, the temperature of stored items was measured under these conditions.

[Problems to be solved by Ill.] However, the above-mentioned conventional method has the following drawbacks. This is because the wire C is broken by 9J due to the pressure of the stored material. It is thought that this is cut due to friction with the storage container when the storage container is transferred.

For this reason, the wire C in which the sensor e was set had to be updated every time the stored items were transferred, which was troublesome and uneconomical.

This invention was made to solve these problems, and its purpose is that once it is installed in a silo, it can be used for a long period of time even if stored items are transferred, and when necessary, it can be used for a long time. It is possible to measure the temperature and gas composition at any position in the height direction of the stored material. An object of the present invention is to provide an apparatus for measuring the temperature and gas composition of stored materials in a silo.

[Means for solving problems]

Referring to drawings showing embodiments of this invention, FIGS.
In FIG. 3, a punching device 3 having a punching tool 2 provided in the main body 1 of the silo and rotating in the circumferential direction and reciprocating in the axial direction; temperature and gas component detection provided in the punching tool 2; Sensor 4; temperature and gas component detection sensor 4
This is a bag for measuring stored temperature and gas composition in a silo, characterized by comprising a display device 5 connected to a silo.

[Effect]

A stored material 7 is housed in the main body 1 of the silo, and when it is desired to know the temperature and gas composition at an appropriate position in the height direction of this stored material 7, the perforated bag 3 is operated,
The drilling tool 2 is moved in the axial direction while rotating in the circumferential direction, and enters into the storage material 7. This approach is storage 7
This is done while drilling holes in the hole. Since the punching tool 2 is equipped with a temperature and gas component detection sensor 4, this sensor 4 detects the temperature and gas components at almost any position in the height direction of the stored object 7 in the display bag ff15. This is recognized by displaying it.

〔Example〕

In FIG. 1, the perforated bag W13 is provided at the lower part of the silo main body l, as an example, and is connected to a cylinder 8. which also serves as a guide. and a rotating rod 9 having a spline (not shown) around the circumference, a piston portion 10 formed at the base end of the drilling tool 2,
A fluid pressure device 3111 that supplies pressurized fluid to the cylinder 8 or stops pressurizing the cylinder 8 and stores the fluid. (FIG. 2) and a drive device 12 for rotating the rotary rod 9. Note that the rotating rod 9 and the drilling tool 2 are spline-coupled, so that the drilling tool 2 can be freely moved in the axial direction and rotated by the rotating rod 9 in the circumferential direction.

Further, the drive device 12 rotates the rotary rod 9 by, for example, a motor and gears 13,14. The fluid used in the fluid fitting 911 is, for example, oil, and by operating the fluid pressure device 11, pressurized oil is pressurized into the cylinder 8 from the communication passage 15, thereby causing the perforation A. ? The piston portion 10 at the lower end is pushed upward. Further, the temperature and gas component detection sensor 4 transmits the detected temperature and gas components of the stored material 7 to the conductor 1.
6, it is connected to an electrode ring 18 provided at the lower end of the rotary rod 9 through a hole 17 formed in the axis thereof, and from this electrode ring 18, through a brush 19, an indicator bag 215 is connected.
It is connected to the. The display device 5 is shown as a thermometer as an example, but the device 5 operates a lamp or a g9 device when the temperature of the storage material 7 exceeds a certain temperature or the gas content exceeds its permissible limit. It may be made to do, and it includes these.

Note that 20 and 21 (FIG. 3) each indicate an insulating member, and 22 is a guide ring.

Further, a drill 23 is formed at the tip of the drilling tool 2.
The rotation allows the store 7 to be perforated. 2
4 is a threaded portion. 25 is when the conductor 16 is stretched or
This is a winder for pulling out or winding up the conductor when it becomes slack.

When measuring the temperature and gas components of the storage section 7, pressure oil is supplied from the fluid pressure device 11 to the cylinder 8, thereby raising the drilling tool 2. At the same time, the drive wave 2112 is driven to rotate the rotary rod 9. As a result, the drilling tool 2 spline-coupled to the rotary rod 9 rotates and rises, entering into the storage material 7 while drilling the storage material 7. And one display device for the temperature and gas composition at any location in the height direction of the stored object 7, which is provided by the sensor 4! It is recognized by i5. still.

The measurement position is the winding amount of fi25, or the digit 2 of punching tool 2! (or the amount of pressurized oil).

Next, when lowering the drilling tool 2 downward, the operation of the fluid pressure device 11 is stopped, the hydraulic pressure is set to O, and the drive device 12 is reversed (compared to the case of raising), and the threaded part 2 is moved downward.
It is lowered by the force in the downward direction generated by the rotation of 4.

In Fig. 1, the drilling rig 3 is installed on the main body 1 of the silo and is suspended, but it may also be installed on a base (not shown) installed on the ground, or it can be placed on the silo main body 1. It can be installed at any location and the axial direction of the punching device can be set in the water direction or in any direction.

〔Effect of the invention〕

Since this issue 1!11 is configured as described above,
If this device is installed in a temperature silo, it can be used for a long period of time, and there is no need to add a new temperature measuring device every time stored items are piled up, as is the case with the conventional method. By setting a sensor that can detect the temperature at the location and components such as oxygen, carbon gas, methane gas, etc. together with or in place of the temperature sensor, the gas components inside the silo can also be known at the same time.
