Description

Technical Field

[0001] The invention relates to the technical field of zircon sand feeding temperature measurement, in particular to a segmented temperature monitoring module for a zircon sand screw conveyor. Background Art

[0002] Zircon sand, also known as zircon sand or zircon, is a mineral mainly composed of zirconium silicate. It is mainly composed of zirconium, silicon and oxygen crystallized from magma during the formation of igneous rocks. It is a very high-quality refractory material. It is often found in coastal sand with ilmenite, rutile, monazite, xenotime and other minerals, and is obtained after separation by water separation, electric separation, magnetic separation and other mineral separation processes. Zircon sand has a wide range of applications in the fields of casting, materials and chemical industries.

[0003] Due to structural limitations, zircon sand is mostly transported in a spiral manner during the transportation process. During the transportation process, in order to improve the transportation efficiency, the temperature of the zircon sand needs to be guaranteed. In order to ensure the accuracy of temperature regulation, the internal temperature of the zircon sand needs to be measured during the transportation process. However, the existing temperature measurement method only measures the temperature at a fixed position, resulting in a single temperature measurement range and inaccurate temperature measurement, which in turn leads to limited temperature control methods and relatively high energy consumption. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing temperature measurement method of zircon sand is to measure the temperature at a fixed position only, resulting in a single temperature measurement range and inaccurate temperature measurement, which in turn leads to limited temperature control methods and relatively high energy consumption.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A segmented temperature monitoring module for a zircon sand screw conveyor is shown, comprising a main material conveying pipeline 1, a main control shaft tube 2 is movably installed inside the main material conveying pipeline 1, a spiral material guide blade 3 is fixedly installed on the outer arc surface of the main control shaft tube 2, an electric control telescopic temperature measuring probe 4 is installed on the outer arc surface of the main control shaft tube 2, and a built-in temperature regulating component 5 controlled by the electric control telescopic temperature measuring probe 4 is installed inside the main control shaft tube 2.

[0025] Working principle: The main control shaft tube 2 is controlled by a driving motor, which drives the spiral guide blades 3 on its surface to transport. The spiral guide blades 3 drive the zircon sand inside the main conveying pipeline 1 to control the material transport. While the zircon sand is being transported, the electrically controlled telescopic temperature measuring probe 4 extends into the zircon sand to measure the internal temperature and humidity of the zircon sand. When the internal temperature and humidity do not reach the specified standards, the built-in temperature control component 5 is controlled to heat up to ensure that the temperature and humidity of the zircon sand at different positions and depths reach the specified values, thereby ensuring its dryness.

[0026] In order to cooperate with telescopic adjustment and guidance, a lateral telescopic hole for installing an electrically controlled telescopic temperature measuring probe 4 is opened on the outer wall of the main control shaft tube 2.

[0027] In order to cooperate with telescopic adjustment and temperature measurement, the electrically controlled telescopic temperature measuring probe 4 includes an electrically controlled support rod 41 fixed inside the lateral telescopic hole, a telescopic sleeve 42 axially fixed to the outer protruding end of the electrically controlled support rod 41, and a temperature sensor 43 fixedly installed on the outer end of the telescopic sleeve 42.

[0028] The telescopic sleeve 42 is controlled to be inserted into the zircon sand by the extension and retraction of the electrically controlled support rod 41 , and the temperature sensor 43 measures the internal temperature of the zircon sand at this time.

[0029] In order to coordinate the synchronous measurement of the humidity of the zircon sand on the surface of the extended end, an embedded humidity sensor module 44 is fixedly installed on the outer arc surface of the telescopic sleeve 42 .

[0030] In order to measure humidity at different depths, the outer arc surface of the telescopic sleeve 42 is provided with an inwardly recessed lateral mounting groove, and the embedded humidity sensor module 44 is fixedly installed in the lateral mounting groove.

[0031] The electrically controlled support rod 41 controls the telescopic sleeve 42 to extend outward, and controls the embedded humidity sensor module 44 to measure the humidity inside the zircon sand. By measuring the humidity at different depths inside the zircon sand, the required drying heat can be determined. At the same time, the inside of the zircon sand can be stirred by the extended telescopic sleeve 42, thereby improving the air circulation inside the zircon sand and further improving the drying effect.

[0032] In order to cooperate with the internal temperature control, the built-in temperature control component 5 includes a central temperature conducting tube 51 fixedly installed in the middle of the main control shaft tube 2, an electrically controlled main temperature control tube 52, a spiral built-in liquid conducting tube 53, a segmented spiral external liquid conducting tube 54, a segmented switching conduit 55 and an electrically controlled regulating valve 56.

[0033] The electrically controlled main temperature control tube 52 is heated by electric heating, which is heated by power supply. Then the heat exchange liquid inside the spiral internal liquid guide tube 53 surrounding the outer periphery of the electrically controlled main temperature control tube 52 absorbs the internal temperature, and then the high-temperature liquid is transferred to the inside of the segmented spiral external liquid guide tube 54. Then, the segmented spiral external liquid guide tube 54 is used to transfer the temperature to the spiral guide blades 3 on the outer curved surface of the main control shaft tube 2 machine. Then, the spiral guide blades 3 drive the zircon sand while heating and drying it.

[0034] When the temperature sensor 43 is inserted into the zircon sand, the temperature of different positions of the zircon sand is measured, and the temperature of the built-in temperature regulating component 5 is controlled according to the temperature difference between the closer and farther distances, thereby ensuring the drying effect of the zircon sand.

[0035] In order to facilitate installation, the electrically controlled main temperature control tube 52 is fixedly installed in the middle of the central temperature conducting tube 51, the spiral internal liquid guiding tube 53 is fixedly installed on the inner arc surface of the central temperature conducting tube 51, the segmented spiral external liquid guiding tube 54 is segmentedly fixed on the inner arc surface of the main control shaft tube 2 along the connecting end of the spiral material guiding blade 3, the segmented switching conduit 55 is fixedly installed on the outer arc surface of the central temperature conducting tube 51, and the electrically controlled regulating valve 56 is fixedly installed on the connecting end of the segmented switching conduit 55; The connection end of the segmented switching catheter 55 includes the connection ends of two adjacent segmented switching catheters and the connection end of the segmented switching catheter 55 and the segmented spiral external catheter 54 .

[0036] When the electrically-controlled telescopic temperature measuring probe 4 detects that the temperature at the segmented position is low and the humidity is high, the electrically-controlled telescopic temperature measuring probe 4 controls the electrically-controlled regulating valve 56 to close the connection between the two adjacent segmented switching conduits, and at the same time opens the connection between the segmented switching conduit 55 and the segmented spiral external liquid guiding tube 54, so that the heat exchange liquid will be introduced into the segmented spiral external liquid guiding tube 54 to heat and dry the zircon sand at this position; on the contrary, when the electrically-controlled telescopic temperature measuring probe 4 detects that the temperature at the segmented position is normal and the humidity is low, the electrically-controlled telescopic temperature measuring probe 4 controls the electrically-controlled regulating valve 56 to open the connection between the two adjacent segmented switching conduits, and at the same time closes the connection between the segmented switching conduit 55 and the segmented spiral external liquid guiding tube 54, so that the heat exchange liquid will be transported from the segmented switching conduit 55 to the position of the electrically-controlled regulating valve 56 of the next segment to avoid heat loss.

[0037] In order to facilitate the reflux, a reflux conduit 57 for connecting the spiral built-in liquid conduit 53 and the segmented switching conduit 55 is fixedly installed on the outer arc surface of the central temperature conducting tube 51 .

[0038] The spiral internal fluid conduit 53 , the segmented spiral external fluid conduit 54 , the segmented switching conduit 55 and the return conduit 57 form a circulating flow channel, and the circulation of the internal fluid is controlled by a circulating liquid pump located inside the main control shaft tube 2 .

[0039] In order to cooperate with pressure monitoring, an annular pressure sensing module 6 is fixedly installed at the end of the telescopic sleeve 42 and located outside the temperature sensor 43 .

[0040] As zircon sand is fed outside the main control shaft tube 2, the zircon sand will squeeze the annular pressure sensing module 6 on the surface of the main control shaft tube 2. When the surface of the annular pressure sensing module 6 senses the pressure value, the electrically controlled telescopic temperature measuring probe 4 will start to extend into the zircon sand, and then synchronously measure the temperature and humidity inside the zircon sand, and then perform temperature control adjustment according to the temperature and humidity, and also adjust the rotation speed of the main control shaft tube 2.

[0041] In order to improve the drying effect, a lateral air jet port 7 is fixedly installed on the outer side of the telescopic sleeve 42, and a built-in flow guide pipe 8 is fixedly installed on the inner arc surface of the telescopic sleeve 42 corresponding to the position of the lateral air jet port 7. An electrically controlled air pump 9 that cooperates with the built-in flow guide pipe 8 is fixedly installed between the main control shaft tube 2 and the central temperature guide tube 51 through a bracket.

[0042] The hot air inside the main control shaft tube 2 can be drawn into the electrically controlled air pump 9 through the electrically controlled air pump 9, and then the hot air is guided to the side air jet 7 through the built-in guide pipe 8, and then blown into the interior of the zircon sand from the side air jet 7, thereby improving the air-drying effect of the zircon sand.

[0043] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
