Description

Technical Field

[0001] The present application relates to the technical field of production safety monitoring, and in particular to a smoldering monitoring device for a dry koji silo, and also to a smoldering monitoring system for a dry koji silo. Background Art

[0002] Liquor Daqu is fermented with wheat as the main raw material, and is divided into two process stages. The first stage is the Daqu production stage, that is, the wheat is moistened and crushed, and the mother koji is added to make the koji blank, which is sent to the fermentation room for pre-fermentation. After the koji blank is sent to the fermentation room, the room temperature gradually rises with the progress of fermentation. When the room temperature rises to 60-70℃, the first koji turning is carried out; after the first turning, when the temperature rises to 55-65℃ again, the second turning is carried out; it takes a total of 40 days from the koji blank entering the fermentation room to leave the fermentation room. At this time, the temperature of the Daqu is about 30℃ and the water content is about 20%. The second stage is the dry koji storage stage. After the Daqu is made, it is sent to the dry koji warehouse for storage, and naturally stacked for post-fermentation. The storage time of the dry koji is about 6 months. The dry koji warehouse is the second stage. After the Daqu becomes dry koji, it is stored in the dry koji warehouse. During the storage of dry koji, due to factors such as ventilation, temperature, humidity in the dry koji warehouse and the spontaneous combustion and heat release of Daqu post-fermentation, the koji blank will smolder, which will have a serious impact on production safety. Smoldering is a form of solid combustion, which is a slow combustion without visible light, usually producing smoke and temperature rise. The difference between it and flaming combustion is that there is no flame. The difference between it and flameless combustion is that it can thermally decompose combustible gas. Therefore, under certain conditions, smoldering can be converted into flaming combustion.

[0003] In addition, after the dry koji bin is filled with dry koji, the height of the dry koji pile is 4.7 meters, and the smoldering area is often concentrated at the bottom of the koji pile. Due to the deep burial depth and the hard dry koji pile, it is very difficult to obtain the fermentation conditions at the bottom of the dry koji pile using existing methods. At the same time, after the dry koji bin is filled, the space at the top of the dry koji pile is very limited (in order to ensure that the storage rate does not waste space, the storage capacity of dry koji cannot be reduced), resulting in the top of the dry koji pile being only about 1.5 meters away from the roof. This requires that the length of the drilling equipment cannot exceed this distance, otherwise it will be difficult to operate.

[0004] The existing method reduces the room temperature of the warehouse and changes the environment for the growth and reproduction of microorganisms by adding ventilation facilities to the dry koji warehouse, but causes the saccharification rate and water content of the finished koji to increase and decrease respectively, which has a significant impact on the quality of the wine and causes significant economic losses. It can be seen that how to prevent the occurrence of smoldering while ensuring the quality of the original koji and without changing the original process has become a problem that needs to be solved urgently by those skilled in the art.

[0059] The existing method reduces the room temperature of the warehouse and changes the environment for the growth and reproduction of microorganisms by adding ventilation facilities to the dry koji warehouse, but causes the saccharification rate and water content of the finished koji to increase and decrease respectively, which has a significant impact on the quality of the wine and causes significant economic losses. Therefore, in order to ensure the quality of the dry koji, the process conditions for storage in the dry koji warehouse cannot be changed. Obtaining the fermentation conditions in the dry koji pile and intervening in time have become important solutions to avoid the smoldering of the dry koji. However, due to the limited space in the dry koji warehouse and the height of the dry koji pile reaching 4.7 meters, it is difficult to obtain the parameters at the bottom of the dry koji pile. How to obtain the fermentation conditions at the bottom of the dry koji pile has become a key issue that needs to be solved urgently.

[0060] Based on this, an embodiment of the present application provides a device for monitoring smoldering in a dry koji warehouse, comprising: a plurality of detection rod groups, a monitoring sleeve, a driving device and a connection assembly, wherein the detection rod group can be plugged into a preset designated position and a preset designated depth of a dry koji pile in a down-drilling manner.

Then, the driving device drives the detection rod group to rotate along a second rotation direction, and the detection rod group is brought out of the dry koji pile, and at the same time the monitoring sleeve remains at the preset designated position and the preset designated depth of the dry koji pile.

[0061] The smoldering monitoring device for dry koji warehouse provided by the present application is provided with a plurality of detection rod groups which are inserted into the preset designated position and preset designated depth of the dry koji pile in a down-drilling manner, so that the monitoring device is not carried out in a pre-buried manner, so that the monitoring point can be monitored at any desired position of the koji pile. At the same time, the driving device drives the detection rod group to rotate along the second rotation direction, and the detection rod group is brought out of the dry koji pile, while the monitoring sleeve is retained at the preset designated position and preset designated depth of the dry koji pile, thereby avoiding the problem of damaging the equipment after the dry koji is dropped and squeezing the sensor to the edge of the dry koji pile. Secondly, the monitoring sleeve can not only obtain the first gas and / or the first temperature associated with the dry koji in the dry koji pile, but also obtain the second gas and / or the second temperature associated with the dry koji warehouse outside the dry koji pile, thereby making the environmental monitoring of the entire dry koji warehouse more comprehensive, and then can comprehensively and accurately monitor the various gas components and temperature information at any position of the dry koji warehouse, and by monitoring the gas and temperature information, it can effectively predict the possible smoldering in advance, and solve the problem of smoldering accident prevention and control.

[0063] like Figures 1 to 7 As shown, the embodiment of the present application provides a smoldering monitoring device for a dry koji storehouse, comprising: a plurality of detection rod groups 10, a monitoring sleeve, a driving device 5 and a connection assembly 4, wherein:

The first nut-type connector 21 is arranged at the first end, the internal thread groove is arranged on the radial end face of the first nut-type connector 21, and the hollow structure 12 is arranged through the bottom of the internal thread groove.

In one example, the structure of the inner circumference of the limiting sleeve 23 is a hexagonal sleeve.

[0067] In addition, in this embodiment, the connection structure 2 further includes an axial limiting member 24, which is mounted on both ends of the limiting sleeve 23 in the direction of the central axis of the detection rod 1 to limit the degree of freedom of the limiting sleeve 23 in the direction of the central axis of the detection rod 1. In one example, the axial limiting member 24 includes a clamp.

[0068] Two adjacent detection rods 1 that need to be connected can be connected via the connection structure 2 .

In one example, a through hole is also provided in the middle of the drill bit 13, and the through hole can be connected to the hollow structure 12 of the detection rod 1, and the aperture of the through hole is equal to the aperture of the hollow structure 12, so that the monitoring casing can be sleeved in the hollow structure 12 and then sleeved in the through hole.

[0070] In one example, the drill bit 13 may be integrally formed with one end of the detection rod 1 at the head end.

The number of detection rods 1 can be set according to the pre-embedded depth relative to the dry koji pile, and is not specifically limited in the description here. It should be noted that the length of each detection rod 1 can be equal or unequal. It should also be noted that the hollow structure 1212 penetrates the first detection rod 102, the second detection rod 1 and the head end detection rod 101, so that the hollow structures 12 in the head end detection rod 101, the first detection rod 102 and the second detection rod 1 are in a connected state.

[0073] At least one filling member 14 is disposed in the hollow structure 12 to fill the hollow structure 12.
