Abstract
The utility model relates to a concrete discharging temperature detector, which belongs to the field of building material detection equipment, and aims at accurately and rapidly detecting the concrete discharging temperature. The concrete discharging temperature detector comprises a discharging bucket, and a detection bench and a temperature measuring mechanism arranged on the inner wall of the discharging bucket, wherein the temperature measuring mechanism is connected with the detection bench. When concrete is discharged from a discharge port, concrete on the detection bench flows more slowly than concrete on the wall of the discharging bucket due to obstruction of the detection bench, and the temperature measuring mechanism is connected with the detection bench to detect the temperature of the concrete. The concrete discharging temperature detector is accurate in detection, high in temperature response speed, and rapid in temperature measurement; and can be applied to rapid detection for concrete temperature after concrete mixing is completed.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Concrete out-of-machine temperature pick-up unit as shown in Figure 1 and Figure 2, comprises discharge hopper 1, and is arranged at monitor station 3 and temperature measuring mechanism 2 on discharge hopper 1 inwall, and temperature measuring mechanism 2 is connected with monitor station 3.
The concrete being stirred is by the blanking hatch door of stirring machine, buffer action by discharge hopper 1 is put in concrete transportation tank car, during concrete process discharge hopper 1, speed is very fast, and due to the inhibition of monitor station 3, the concrete on monitor station 3 can flow slower than the concrete on discharge hopper 1 wall.Now, temperature measuring mechanism 2 is connected with monitor station 3, and 22 response times of infrared thermometry device in the 3 upper residence time of monitor station, can be carried out the detection of concrete temperature on monitor station 3 much smaller than concrete, fast and accurately, can finely measure and discharge concrete temperature.
In order to guarantee to detect under the prerequisite of quality, simplify the structure of temperature measuring mechanism 2, temperature measuring mechanism 2 consists of temperature tube 21 and infrared thermometry device 22, the entrance point 211 of temperature tube 21 is arranged on discharge hopper 1 inwall, the endpiece 212 of temperature tube 21 extends to the horizontal level at outer and endpiece 212 places of discharge hopper 1 higher than the horizontal level of entrance point 211, and infrared thermometry device 22 is arranged at endpiece 212 and infrared thermometry device 22 is connected by infrared detection ray with monitor station 3.The horizontal level at temperature tube 21 endpiece 212 places, higher than the horizontal level of entrance point 211, is flow into and infrared thermometry device 22 is destroyed along temperature tube 21 for fear of concrete.Infrared thermometry device 22 with by concrete temperature on acquisition testing platform 3, carry out the detection of temperature.
On the basis of such scheme, in order to prevent from pouring concrete into, the concrete splashing destroys infrared thermometry device 22, can select temperature tube 21 for straight tube, and the axis of temperature tube 21 is through the wall of discharge hopper 1.Straight tube need be only general siphunculus, and the axis of temperature tube 21 is through the wall of discharge hopper 1, can be away from the axis of discharge hopper 1 so be arranged on the infrared thermometry device 22 of temperature tube 21 upper outlet ends 212, and away from the concrete of toppling over from top to bottom.
For the infrared-ray that allows infrared thermometry device 22 detect more abundant, improve Detection accuracy, can select such scheme: described monitor station 3 comprises detection faces 31 and supporting surface 32, detection faces 31 is some P, the line between infrared thermometry device 22 and described P point and the axes intersect of discharge hopper 1 with the mid point of discharge hopper 1 intersection.By allowing monitor station 3 and infrared thermometry device 22 be distributed in the plane coplanar with discharge hopper 1 axis, infrared thermometry device 22 can, over against the concrete on monitor station 3, gather abundanter concrete infrared energy.
Especially, when practical application, should note the state of designed concrete on monitor station 3.Concretely: the optical resolution of infrared thermometry device 22 equals L divided by the visual field S of infrared thermometry device 22.As shown in Figure 1, L refers to the air line distance that infrared thermometry device 22 to P is ordered, and visual field S refers to that infrared thermometry device 22 gathers the diameter of infrared energy passage sections, i.e. infrared thermometry device 22 optical resolution η=L/S.The S that is greater than that should guarantee designed concrete diameter d on test board, S/d is preferably less than 0.8, is further preferably less than 0.6, is particularly preferably less than 0.5.Therefore when choosing infrared thermometry device 22, should be in conjunction with concrete concrete parameter to be detected, and the structure of monitor station 3 is carried out concrete analysis.
Line between infrared thermometry device 22 and P point and the angle α of surface level are 5 °～30 °.When concrete application, the too little concrete of α easily enters testing tube, causes testing tube to stop up, and α causes too greatly infrared thermometry device 22 excessive to designed concrete distance, need to improve the optical resolution of infrared thermometry device 22.α can be 5 °～30 °, preferably 10 °～20 ° conventionally.
The scope of 22 response times of infrared thermometry device is 1ms～500ms, this is to detect in conjunction with infrared thermometry device 22 the reasonable response time that designed concrete draws, when specifically choosing, the response time is generally 1ms～500ms, preferred 1ms～100ms, particularly preferably 1ms～10ms.

Detection faces 31 is-10 °～30 ° with the angle γ of surface level.The angle of described monitor station 3 planes and surface level is γ, γ too the general objective concrete residence time too short, γ is too little or easily pile up for negative designed concrete, γ is generally-10 °～30 °, preferably-5～15 °.The negative angle is here the angle that monitor station 3 planes are with respect to the horizontal plane rotated counterclockwise formation.
Angle β between the supporting surface 32 of monitor station 3 and discharge hopper 1 central axis is-60 °～60 °.The supporting surface 32 of described monitor station 3 is β with the angle of discharge hopper 1 central axis, and β is excessive easily causes concrete buildup on monitor station 3, and β is too small easily causes the designed concrete residence time too short, and infrared thermometry device 22 cannot be measured temperature in time.β is generally-60 °～60 °, and preferably-30 °～30 °, particularly preferably 0 °.
When temperature tube 21 inner accumulated have concrete, dust and affect the test of infrared thermometry device 22, by infrared thermometry device 22 from temperature tube 21 is pulled down, temperature tube 21 and infrared thermometry device 22 are cleared up, the concrete removing residues in temperature tube 21 is fallen, the Sensor section of infrared thermometry device 22 is stained with to deionized water cleaning with cotton swab.
