Description

Technical Field

[0001] The invention belongs to the technical field of water absorption detection of ceramic tiles, and in particular relates to a device for detecting water absorption of ceramic tiles. Background Art

[0002] The methods for testing the water absorption of ceramic tiles include boiling method and vacuum method. The boiling method is to place the bricks vertically in a heating device filled with deionized water so that the bricks do not touch each other; the upper and lower parts of the bricks should be kept with water at a depth of not less than 5 cm; the water is heated to boiling and kept boiling for 2 hours; then the heat source is cut off, the brick is completely immersed in water and cooled to room temperature, and kept for 4±0.25 hours; the sample can also be cooled to room temperature using water at room temperature or a refrigerator; a soaked suede is wrung out by hand, and the suede is placed on a platform to gently wipe the surface of each brick in turn. For concave and convex or embossed surfaces, the surface moisture should be wiped off briskly with suede, and then weighed, and the weighing result of each sample is recorded to calculate the water absorption of the ceramic tile. The difference between the weighed mass after water absorption and the mass of the dry brick in its natural state is used to determine the water absorption rate of the brick. The vacuum method is to place the brick vertically in a vacuum container so that the bricks do not touch each other, evacuate to 10±1kPa, and stop evacuating after maintaining for 30 minutes, add enough water to cover the brick by no less than 5cm, and take out the brick after soaking for 15 minutes; wring out a soaked suede by hand; place the suede on the platform and gently wipe the surface of each brick in turn. For the uneven or embossed surface, use the suede to briskly wipe off the surface moisture, then weigh and record immediately, calculate the difference between the weighed mass of the brick after water absorption and the mass of the dry brick in its natural state, and determine the water absorption rate of the brick based on the difference.

[0003] At present, when the boiling method is used to detect the water absorption of ceramic tiles, the ceramic tiles need to be placed in a support frame. During the boiling method detection process, the ceramic tiles will always be in contact with the support frame, resulting in the contact part between the ceramic tiles and the support frame being unable to directly contact with water, which in turn affects the overflow of gas at the contact part between the ceramic tiles and the support frame, resulting in the water absorption of the contact part between the ceramic tiles and the support frame becoming worse, thereby affecting the accuracy of detecting the water absorption of the ceramic tiles.

[0015] The beneficial effects of the present invention are: 1. The present invention uses a supporting mechanism and a displacement mechanism in coordination. When the boiling method is used to detect the water absorption of ceramic tiles, during the process of the electric heater heating water, the displacement mechanism will work intermittently to push the ceramic tiles up and down, so that the ceramic tiles are intermittently in contact with the supporting mechanism, and the displacement mechanism is intermittently in contact with the ceramic tiles. When the ceramic tiles are only in contact with the supporting mechanism, the pressure on the supporting spring will increase, which will cause the supporting spring to generate elastic force and thus cause the ceramic tiles to shake slightly. When the ceramic tiles are only in contact with the displacement mechanism, the pressure on the shaking spring will increase, which will cause the shaking spring to generate elastic force and thus cause the ceramic tiles to shake slightly, so that all parts of the ceramic tiles can contact with water. At the same time, when the ceramic tiles are slightly shaken, the gas overflowing from the ceramic tiles attached to the outer surface of the ceramic tiles can be separated from the ceramic tiles, thereby improving the water absorption efficiency of the ceramic tiles, thereby ensuring the accuracy and efficiency of the detection of the water absorption of the ceramic tiles.

[0016] 2. The present invention enables the water guide plate and the displacement plate to move up and down back and forth through the operation of the displacement mechanism. When the displacement plate and the water guide plate move downward, they will squeeze the water at the bottom of the displacement plate, so that the water at the bottom of the displacement plate impacts the ceramic bricks under the guiding effect of the water guide plate, so that the water around the ceramic bricks is in a flowing state, and the flowing water can better carry away the gas overflowed from the inside of the ceramic bricks attached to the ceramic bricks, avoiding the existence of bubbles around the ceramic bricks due to the gas overflowed from the inside of the ceramic bricks, resulting in the inability of water to fully contact the ceramic bricks, thereby ensuring the complete contact between the ceramic bricks and the water, improving the efficiency of the gas overflowing from the ceramic bricks, and thus improving the efficiency of the water absorption detection of the ceramic bricks.

[0017] 3. The present invention uses an exhaust mechanism, an exhaust pipe and a one-way valve installed in the exhaust pipe in coordination. When the displacement mechanism is working, the exhaust mechanism will intermittently absorb the gas inside the detection box. At this time, since the one-way valve is installed in the exhaust pipe, the gas inside the detection box can only be discharged through the exhaust pipe, and the external gas cannot enter the detection box through the exhaust pipe. At this time, the air pressure inside the detection box will be reduced, and the gas inside the ceramic tile can overflow the ceramic tile faster, thereby improving the water absorption efficiency of the ceramic tile. In addition, since the exhaust mechanism intermittently extracts the gas inside the detection box, it will not affect the physical properties of the ceramic tile, thereby ensuring the accuracy of the water absorption detection of the ceramic tile and improving the detection efficiency.

[0018] 4. The present invention cooperates with the displacement mechanism, the air extraction mechanism and the air injection mechanism. During the downward movement of the displacement mechanism, the gas in the air extraction mechanism will enter the air injection mechanism and be blown toward the two sides of the ceramic brick through the air injection mechanism. Since the gas inside the detection box extracted by the air extraction mechanism is hot gas, the hot gas pushes the water flow to generate an impact force, so that the impact force generated by the water flow acts on the two sides of the ceramic brick, accelerating the overflow speed of the gas inside the ceramic brick and the speed of water penetrating into the ceramic brick, which helps to achieve the purpose of detecting the water absorption of the ceramic brick in a shorter time. In this process, the ceramic brick moves downward, and the water on both sides of the ceramic brick will move upward relative to the ceramic brick. At this time, the impact force generated by the water flow driven by the hot gas blown to both sides of the ceramic brick can quickly carry the gas overflowing from the ceramic brick away from the two sides of the ceramic brick, and avoid the gas overflowing from the ceramic brick to form bubbles around the ceramic brick, thereby expanding the contact area between water and the ceramic brick, and improving the detection efficiency and detection accuracy.

DETAILED DESCRIPTION

[0021] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example: Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, a device for detecting water absorption of ceramic tiles comprises a detection box 1, a weighing scale 5, a water supply pipe 6, an exhaust pipe 7 and an electric heater 8. A water level sensor is installed in the detection box 1 (the water level sensor is a prior art, not shown in the figure, and will not be described in detail here). A box door 2 is installed in front of the detection box 1. The arrangement of the box door 2 facilitates opening the detection box 1, and is convenient for storing and taking ceramic tiles. The box door 2 is sealed and connected to the detection box 1 to ensure the sealing of the detection box 1 when detecting the water absorption of ceramic tiles. A controller 3 is installed on the box door 2. The controller 3 is used to control the heating temperature and heating time of the electric heater 8. A water temperature sensor is installed in the detection box 1 (the water temperature sensor is a prior art, not shown in the figure, and will not be described in detail here). It is used to detect the water temperature in the detection box 1 and feed back the detected data to the controller 3. The controller 3 adjusts the heating temperature of the water by the electric heater 8 according to the detected data. A support platform 4 is fixedly connected in front of the detection box 1. The weighing scale 5 is installed on the top of the support platform 4, the water supply pipe 6 is fixedly connected to the side wall of the detection box 1, the water supply pipe 6 is connected to the external water source, a water valve is installed in the water supply pipe 6, the water valve is controlled by the controller 3, the controller 3 controls the opening and closing of the water valve so that the water in the external water source enters the detection box 1, and controls the water level sensor to detect the amount of water inside the detection box 1. When the water level sensor detects that the height of the water inside the detection box 1 is more than five centimeters greater than the maximum moving distance of the ceramic brick, the water supply is stopped. The exhaust pipe 7 is fixedly connected to the top of the detection box 1, and a one-way valve is installed in the exhaust pipe 7. The one-way valve installed in the exhaust pipe 7 allows the gas inside the detection box 1 to be discharged only through the exhaust pipe 7. The electric heater 8 is fixedly connected to the inside of the detection box 1, and the side wall of the detection box 1 is fixedly connected to the drain pipe 13, and a valve is installed in the drain pipe 13. The opening and closing of the valve is controlled by the controller 3. It also includes: a supporting mechanism 9, the supporting mechanism 9 is fixedly connected in the detection box 1, and the supporting mechanism 9 is used to support ceramic bricks. Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10The a in the figure are all ceramic tiles. The supporting mechanism 9 includes a fixed plate 901 fixedly connected in the detection box 1. The fixed plate 901 is located above the electric heater 8. The top of the fixed plate 901 is fixedly connected with a supporting rod 902. The supporting rod 902 is arranged in ten groups, and the water absorption test of ten ceramic tiles can be performed at the same time. The top of the supporting rod 902 is fixedly connected with a supporting frame 903. The inner bottom of the supporting frame 903 is fixedly connected with a supporting spring 904. The top of the supporting spring 904 is fixedly connected with a supporting plate 905. The supporting plate 905 is attached to the inner surface of the supporting frame 903. The ceramic tiles are placed on the top of the supporting plate 905 and are in the supporting frame 903.

[0023] When in use, first prepare ten ceramic bricks to be tested with basically the same size, shape and quality, and ensure the cleanliness of the ceramic bricks, then open the box door 2, and weigh the ten ceramic bricks in turn through the weighing scale 5, and record the dry brick mass of the ceramic bricks in the natural state, then place the weighed ceramic bricks on the top of the supporting plate 905 respectively, and make the ceramic bricks located in the supporting frame 903, then close the box door 2, close the valve in the drain pipe 13 through the controller 3, and open the water valve in the water supply pipe 6 at the same time, so that the external water source injects water into the detection box 1, and control the water level sensor to detect the amount of water inside the detection box 1 until the water is full. When the position sensor detects that the height of the water inside the detection box 1 is more than five centimeters greater than the maximum moving distance of the ceramic tile, the water addition is stopped. At this time, the electric heater 8 can be started through the controller 3, and the heating temperature and heating time of the electric heater 8 can be set. The heating of the electric heater 8 will increase the internal air pressure of the detection box 1. This is because when the electric heater 8 is heated, the gas inside the detection box 1 will expand under the action of temperature. At the same time, the heating of the electric heater 8 will cause the water to evaporate under the action of temperature, further increasing the internal air pressure of the detection box 1. At this time, the detection box 1 will discharge gas to the outside through the exhaust pipe 7.

[0024] like Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, the ceramic tile water absorption detection device also includes: a displacement mechanism 10, which is installed in the middle of the detection box 1. The displacement mechanism 10 is used to change the height of the ceramic tile and change the contact state between the ceramic tile and the supporting mechanism 9. The displacement mechanism 10 includes a driving motor 1001 installed on the top of the detection box 1. The working time and rotation speed of the driving motor 1001 are controlled by the controller 3. The output end of the driving motor 1001 is fixedly connected to a rotating shaft 1002, which passes through the top of the detection box 1 and is rotatably connected to the detection box 1. The rotating shaft 1002 passes through the fixed plate 901 and is rotatably connected to the fixed plate 901. The outer surface of the lower end of the rotating shaft 1002 is provided with a first reciprocating wire 1009. The first reciprocating wire 1009 is of the same type as the reciprocating wire on the outer surface of the reciprocating screw rod. The outer surface of the rotating shaft 1002 is connected with a displacement plate 1003 through the first reciprocating wire 1009. The displacement plate 1003 is arranged below the fixed plate 901 and above the electric heater 8. The displacement plate 1003 is slidably connected to the fixed plate 901. Both sides of the displacement plate 1003 are fixedly connected with The water guide plate 1004 is set to an arc shape, and the arc shape faces the two ends of the ceramic brick, so that when the water guide plate 1004 moves downward, the water flow generated by the displacement plate 1003 is squeezed through the water guide plate 1004 and impacts the ceramic brick. The top of the displacement plate 1003 is fixedly connected with a displacement rod 1005. The number of the displacement rod 1005 and the supporting rod 902 is the same. The displacement rod 1005 passes through the fixed plate 901 and is slidably connected to the fixed plate 901. The top of the displacement rod 1005 is fixedly connected with a displacement frame 1006. The size is the same as that of the supporting frame 903. The inner bottom of the displacement frame 1006 is fixedly connected with a shaking spring 1007. The specifications of the shaking spring 1007 are the same as those of the supporting spring 904, and they are both made of the same material. The top of the shaking spring 1007 is fixedly connected with a shaking plate 1008. When no ceramic tiles are placed, the top of the shaking plate 1008 and the top of the supporting plate 905 are at the same height. The shaking plate 1008 fits in the displacement frame 1006, and the ceramic tiles are placed on the top of the shaking plate 1008 and are located in the displacement frame 1006.

[0025] In the initial stage, the shaking plate 1008 and the supporting plate 905 are on the same horizontal plane, and the displacement plate 1003 is in the middle of the first reciprocating wire 1009. When the ceramic brick is placed on the top of the supporting plate 905 and placed in the supporting frame 903, the ceramic brick will be located on the top of the shaking plate 1008 and in the displacement frame 1006. The electric heater 8 heats the water and starts the driving motor 1001 to rotate the rotating shaft 1002, thereby causing the displacement plate 1003 to move from the middle through the first reciprocating wire 1009. The position moves upward, and in the process of moving to the top, it will move downward, and so on until the electric heater 8 stops heating. In the process of the displacement plate 1003 moving upward from the middle, the displacement rod 1005, the displacement frame 1006, the shaking spring 1007 and the shaking plate 1008 will push the ceramic brick to move upward, so that the ceramic brick will be separated from the supporting frame 903 and the supporting plate 905. At this time, since the ceramic brick loses the support of the supporting plate 905 and the supporting spring 904, the shaking plate 1008 and the shaking spring 1007 will be The pressure increases, causing the ceramic brick to shake slightly. In the process of the displacement plate 1003 moving downward from the top to the middle, the ceramic brick will contact the support frame 903 and the support plate 905 again. At this time, the displacement plate 1003 will continue to move downward, causing the displacement frame 1006 and the shaking plate 1008 to break away from the contact state with the ceramic brick. At this time, since the ceramic brick loses the support of the shaking plate 1008 and the shaking spring 1007, the pressure on the supporting plate 905 and the supporting spring 904 will increase, causing the ceramic brick to shake slightly. Therefore, during the heating process of the electric heater 8, the ceramic tile will be in a shaking state intermittently, and at the same time, it will be in contact with the supporting frame 903 and the supporting plate 905 as well as the displacement frame 1006 and the shaking plate 1008 intermittently, so that all parts of the ceramic tile can be in full contact with water, ensuring the uniformity of water absorption of all parts of the ceramic tile. At the same time, when the ceramic tile is slightly shaken, the gas overflowing from the ceramic tile attached to the outer surface of the ceramic tile can be separated from the ceramic tile, thereby improving the water absorption efficiency of the ceramic tile, thereby ensuring the accuracy and efficiency of the water absorption detection of the ceramic tile; In this process, when the displacement plate 1003 moves downward, it will squeeze the water at the bottom of the displacement plate 1003, so that the water at the bottom of the displacement plate 1003 impacts the ceramic bricks under the guiding effect of the water guide plate 1004, so that the water around the ceramic bricks is in a flowing state, and the ceramic bricks are in a slightly shaking state, and the flowing water can better carry away the gas overflowed from the inside of the ceramic bricks attached to the ceramic bricks, and avoid the existence of bubbles around the ceramic bricks due to the gas overflowing from the inside of the ceramic bricks, which causes the water to be unable to fully contact with the ceramic bricks, thereby ensuring the complete contact between the ceramic bricks and the water, improving the efficiency of the gas overflowing from the ceramic bricks, and thus improving the efficiency of the water absorption detection of the ceramic bricks. At the same time, the up and down reciprocating movement of the displacement plate 1003 and the water guide plate 1004 can make the water in the detection box 1 more evenly heated, thereby ensuring the uniformity of the water temperature, avoiding the uneven heating of the ceramic bricks due to the uneven water temperature, resulting in uneven expansion of the ceramic bricks, thereby avoiding the change of the physical structure of the ceramic bricks, and further ensuring the accuracy of the water absorption detection of the ceramic bricks.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig.10As shown, the ceramic tile water absorption detection device also includes: an air suction mechanism 11, the air suction mechanism 11 is fixedly connected to the inner top of the detection box 1, the air suction mechanism 11 is driven by the displacement mechanism 10, the air suction mechanism 11 is used to extract the gas inside the detection box 1, and inject water on both sides of the ceramic tile to impact the two sides of the ceramic tile, the air suction mechanism 11 can reduce the internal air pressure of the detection box 1, the air suction mechanism 11 includes a piston chamber 1101 fixedly connected to the inner top of the detection box 1, and the rotating shaft 1002 passes through the piston chamber 1101 and is connected to the movable The piston chamber 1101 is sealed and rotatably connected, and both sides of the piston chamber 1101 are fixedly connected with an air inlet pipe 1102, and a one-way valve is installed in the air inlet pipe 1102, so that the piston chamber 1101 can only extract the internal gas of the detection box 1 through the air inlet pipe 1102 (it should be noted that when the piston chamber 1101 extracts the internal gas of the detection box 1 through the air inlet pipe 1102, the air extraction amount of the air inlet pipe 1102 will be greater than the amount of steam generated by the electric heater 8, and the exhaust pipe 7 can only exhaust to the outside, and the outside air The body cannot enter the detection box 1 through the exhaust pipe 7, so the detection box 1 will be in a short low-pressure state). The piston plate 1103 is sealed and slidably connected in the piston chamber 1101. The outer surface of the rotating shaft 1002 is provided with a second reciprocating wire 1106. The second reciprocating wire 1106 is of the same type as the reciprocating wire on the outer surface of the reciprocating screw rod. The rotating shaft 1002 passes through the piston plate 1103 and is connected to the piston plate 1103 through the second reciprocating wire 1106. A connecting groove 1106 is provided in the rotating shaft 1002. 105. The portion of the rotating shaft 1002 located in the piston chamber 1101 is provided with an exhaust hole 1104, and the exhaust hole 1104 is communicated with the interior of the connecting groove 1105. The piston chamber 1101 is communicated with the interior of the connecting groove 1105 through the exhaust hole 1104. A one-way valve is installed in the connecting groove 1105, so that the gas in the piston chamber 1101 can only be discharged through the exhaust hole 1104. The lower end side wall of the rotating shaft 1002 is provided with an injection hole 1107, and the injection hole 1107 is communicated with the interior of the connecting groove 1105.

[0027] When the rotating shaft 1002 rotates, the second reciprocating wire 1106 will make the piston plate 1103 slide up and down in the piston chamber 1101. When the piston plate 1103 slides upward in the piston chamber 1101, the gas inside the detection box 1 will be extracted through the air inlet pipe 1102. At this time, since the water inside the detection box 1 is heated by the electric heater 8, the water will evaporate and generate water vapor under the action of temperature. Therefore, the gas inside the detection box 1 extracted by the air inlet pipe 1102 is hot gas with a higher temperature, so that the inside of the detection box 1 is in a short-term low-pressure state (it should be noted that although the piston plate 1103 slides upward in the piston chamber 1101, the air inlet pipe 1102 extracts the gas inside the detection box 1, but in the piston chamber 1101, the piston plate 1103 slides upward, so that the air inlet pipe 1102 extracts the gas inside the detection box 1. When the plate 1103 reaches the top of the piston chamber 1101, the air extraction will stop. At this time, the water inside the detection box 1 is still in an evaporating state, so the inside of the detection box 1 can only be in a short low-pressure state), thereby allowing the gas inside the ceramic tile to overflow the ceramic tile faster under the action of the detection box 1 that is briefly in a low-pressure state, thereby improving the efficiency of the ceramic tile in absorbing water. In addition, since the piston chamber 1101 intermittently extracts the gas inside the detection box 1, the detection box 1 is only in a short low-pressure state, which can be restored when the piston plate 1103 reaches the top of the piston chamber 1101 and starts to move downward. Therefore, it will not affect the physical properties of the ceramic tile, thereby ensuring the accuracy of the detection of the water absorption of the ceramic tile and improving the detection efficiency.

[0028] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.12 and Fig.13As shown, the ceramic tile water absorption detection device also includes: an air injection mechanism 12, the air injection mechanism 12 is fixedly connected to the inner wall of the detection box 1, and is communicated with the inside of the air extraction mechanism 11, the air injection mechanism 12 is connected to the displacement mechanism 10, and the exhaust ends of the air injection mechanism 12 are located on both sides of the ceramic tile. The air injection mechanism 12 includes a fixed sleeve 1201 fixedly connected to the detection box 1, the fixed sleeve 1201 is located below the displacement plate 1003, and the side wall of the fixed sleeve 1201 is fixedly connected with a connecting hose 1202, the connecting hose 1202 is communicated with the inside of the fixed sleeve 1201, the fixed sleeve 1201 is sealed and rotatably connected to the rotating shaft 1002, and the fixed sleeve 1201 is arranged at a position where the rotating shaft 1002 is provided with an air injection hole 1107, and the air injection hole 1107 is located in the fixed sleeve 1201, and the fixed sleeve 1201 is connected to the inside of the air injection hole 1107. The connecting hose 1202 is fixedly connected to the bottom of the displacement plate 1003. A ventilation groove 1203 is provided in the displacement plate 1003, and the ventilation groove 1203 is connected to the inside of the connecting hose 1202. A gas delivery groove 1204 is provided in the displacement rod 1005, and the gas delivery groove 1204 is connected to the inside of the ventilation groove 1203. An air jet groove 1205 is provided in the displacement frame 1006, and the air jet groove 1205 is connected to the inside of the air delivery groove 1204. An air jet hole 1206 is provided on the top of the displacement frame 1006, and the air jet hole 1206 is connected to the inside of the air jet groove 1205. The air jet hole 1206 is inclined and faces the ceramic tile.

[0029] When the piston plate 1103 slides downward from the top along the inner wall of the piston chamber 1101, the hot gas in the piston chamber 1101 will enter the connecting groove 1105 through the exhaust hole 1104, and then be injected into the fixing sleeve 1201 through the gas injection hole 1107. The gas entering the fixing sleeve 1201 will enter the ventilation groove 1203 through the connecting hose 1202, and the ventilation groove 1203 will evenly transport the gas to multiple gas delivery grooves 1204, and finally enter the gas injection groove 1205, and be blown to the two sides of the ceramic brick through the gas injection hole 1206. Since the gas inside the detection box 1 extracted by the piston chamber 1101 is hot gas, the hot gas pushes the water flow to generate an impact force, so that the impact force generated by the water flow acts on both sides of the ceramic brick, accelerating the overflow speed of the gas inside the ceramic brick and the speed of water penetrating into the ceramic brick, which helps to achieve the purpose of detecting the water absorption of the ceramic brick in a shorter time. In this process, the displacement frame 1006 is from the top The ceramic bricks 1006 move downward, and in the process of moving downward from the top to the middle position, the ceramic bricks also move downward, and the water on both sides of the ceramic bricks will move upward relative to the ceramic bricks. At this time, the impact force generated by the water flow driven by the hot gas blown to both sides of the ceramic bricks can quickly carry the gas overflowing from the inside of the ceramic bricks away from the two sides of the ceramic bricks, and avoid the gas overflowing from the inside of the ceramic bricks to form bubbles around the ceramic bricks, thereby expanding the contact area between the water and the ceramic bricks, and improving the detection efficiency and detection accuracy. When the ceramic bricks are not moving, the displacement frame 1006 will continue to move downward until the piston plate 1103 moves to the lowest position, and at this time the displacement plate 1003 is also in the lowest position. In this process, the gas blown out of the air jet hole 1206 will push the water flow to impact the ceramic bricks, and will act on the bottom of the ceramic bricks, and the bubbles overflowing from the bottom of the ceramic bricks and inside the ceramic bricks will be taken away from the ceramic bricks through the impact of the water flow, ensuring that all parts of the ceramic bricks are in full contact with water.

[0030] The specific working principle of the present invention is as follows: in the initial stage, the shaking plate 1008 and the supporting plate 905 are on the same horizontal plane, and the displacement plate 1003 is in the middle position of the first reciprocating wire 1009. When in use, first prepare ten ceramic bricks to be tested with basically the same size, shape and quality, and ensure the cleanliness of the ceramic bricks, then open the box door 2, and use the weighing scale 5 to weigh the ten ceramic bricks in turn, and ensure the cleanliness of the weighing scale 5 during each weighing, and record the weighed mass, then place the weighed ceramic bricks on the top of the supporting plate 905 respectively, and make the ceramic bricks located in the supporting frame 903, and at the same time make the ceramic bricks located on the top of the shaking plate 1008 and located in the displacement frame 1006, then the box door 2 can be closed, and the valve in the drain pipe 13 can be closed through the controller 3, and at the same time When the water valve in the water supply pipe 6 is opened, the external water source injects water into the detection box 1, and the water level sensor is controlled to detect the amount of water in the detection box 1, until the water level sensor detects that the height of the water in the detection box 1 is greater than the maximum moving distance of the ceramic tile by more than five centimeters, then the water supply is stopped. At this time, the electric heater 8 can be started by the controller 3, and the heating temperature and heating time of the electric heater 8 can be set. The heating of the electric heater 8 will increase the internal air pressure of the detection box 1. At this time, the detection box 1 will discharge gas to the outside through the exhaust pipe 7. When the electric heater 8 heats the water in the detection box 1, the water temperature in the detection box 1 is detected by the water temperature sensor. When the water temperature reaches the boiling water state, the controller 3 will automatically adjust the heating temperature of the electric heater 8 so that the water is always in a boiling state. The electric heater 8 heats the water while starting the drive motor 1001, causing the rotating shaft 1002 to rotate, and then the displacement plate 1003 moves upward from the middle position through the first reciprocating wire 1009, and in the process of moving to the top, it will move downward, and so on until the electric heater 8 stops heating. In the process of the displacement plate 1003 moving upward from the middle, the displacement rod 1005 and the displacement frame 1006 as well as the shaking spring 1007 and the shaking plate 1008 will push the ceramic brick to move upward, so that the ceramic brick is out of the way. The supporting frame 903 and the supporting plate 905, at this time, because the ceramic brick loses the support of the supporting plate 905 and the supporting spring 904, the pressure on the shaking plate 1008 and the shaking spring 1007 will increase, causing the ceramic brick to shake slightly. This is because there is no damping structure in the shaking plate 1008 and the displacement frame 1006. The sudden increase in pressure will cause the shaking spring 1007 to deform, thereby causing the ceramic brick to shake slightly. In the process of the displacement plate 1003 moving from the top to the middle, The ceramic brick is in contact with the supporting frame 903 and the supporting plate 905 again. At this time, the displacement plate 1003 will continue to move downward, so that the displacement frame 1006 and the shaking plate 1008 are out of contact with the ceramic brick. At this time, since the ceramic brick loses the support of the shaking plate 1008 and the shaking spring 1007, the pressure on the supporting plate 905 and the supporting spring 904 will increase, causing the ceramic brick to shake slightly (the principle is the same as the shaking principle caused by the ceramic brick losing the support of the supporting plate 905 and the supporting spring 904). During the heating process of the electric heater 8, the ceramic tile will be in a shaking state intermittently, and at the same time, it will be in contact with the supporting frame 903 and the supporting plate 905 as well as the displacement frame 1006 and the shaking plate 1008 intermittently, so that all parts of the ceramic tile can be in full contact with water, ensuring the uniformity of water absorption of all parts of the ceramic tile. At the same time, when the ceramic tile is slightly shaken, the gas overflowing from the ceramic tile attached to the outer surface of the ceramic tile can be separated from the ceramic tile, thereby improving the water absorption efficiency of the ceramic tile, thereby ensuring the accuracy and efficiency of the water absorption detection of the ceramic tile; In this process, when the displacement plate 1003 moves downward, it will squeeze the water at the bottom of the displacement plate 1003, so that the water at the bottom of the displacement plate 1003 impacts the ceramic bricks under the guiding effect of the water guide plate 1004, so that the water around the ceramic bricks is in a flowing state, and the flowing water can better carry away the gas overflowed from the inside of the ceramic bricks attached to the ceramic bricks, avoiding the existence of bubbles formed by the gas overflowed from the inside of the ceramic bricks around the ceramic bricks, resulting in the water being unable to fully contact with the ceramic bricks, thereby ensuring the complete contact between the ceramic bricks and the water, improving the efficiency of the gas overflowing from the ceramic bricks, thereby improving the efficiency of the water absorption detection of the ceramic bricks, and at the same time, the up and down reciprocating movement of the displacement plate 1003 and the water guide plate 1004 can make the water in the detection box 1 more uniformly heated, thereby ensuring the uniformity of the water temperature, avoiding the uneven heating of the ceramic bricks due to the uneven water temperature, resulting in uneven expansion of the ceramic bricks, thereby avoiding the change of the physical structure of the ceramic bricks, and further ensuring the accuracy of the water absorption detection of the ceramic bricks; And in this process, when the rotating shaft 1002 rotates, the second reciprocating wire 1106 will make the piston plate 1103 slide up and down in the piston chamber 1101. When the piston plate 1103 slides upward in the piston chamber 1101, the gas inside the detection box 1 will be extracted through the air inlet pipe 1102. At this time, because the water inside the detection box 1 is heated by the electric heater 8, the water will evaporate and generate water vapor under the action of temperature. Therefore, the gas inside the detection box 1 extracted by the air inlet pipe 1102 is hot gas with a higher temperature, so that the inside of the detection box 1 is in a short-term low-pressure state (it should be noted that although the piston plate 1103 slides upward in the piston chamber 1101, the air inlet pipe 1102 extracts the gas inside the detection box 1, When the piston plate 1103 reaches the top of the piston chamber 1101, the air extraction will stop, and at this time, the water inside the detection box 1 is still in an evaporating state, so the inside of the detection box 1 can only be in a short low-pressure state), so that the gas inside the ceramic tile can overflow the ceramic tile faster under the effect of the detection box 1 that is briefly in a low-pressure state, thereby improving the efficiency of the ceramic tile in absorbing water. In addition, since the piston chamber 1101 intermittently extracts the gas inside the detection box 1, the detection box 1 is only in a short low-pressure state, which can be restored when the piston plate 1103 reaches the top of the piston chamber 1101 and starts to move downward, so it does not affect the physical properties of the ceramic tile, thereby ensuring the accuracy of the detection of the water absorption of the ceramic tile and improving the detection efficiency; When the piston plate 1103 slides downward from the top along the inner wall of the piston chamber 1101, the hot gas in the piston chamber 1101 will enter the connecting groove 1105 through the exhaust hole 1104, and then be injected into the fixing sleeve 1201 through the gas injection hole 1107. The gas entering the fixing sleeve 1201 will enter the ventilation groove 1203 through the connecting hose 1202, and the ventilation groove 1203 will evenly transport the gas to the multiple gas delivery grooves 1204, and finally enter the gas injection groove 1205, and the gas will be discharged by the gas injection hole 1107. The hole 1206 blows toward both sides of the ceramic tile. Since the gas inside the detection box 1 extracted by the piston chamber 1101 is hot gas, the hot gas pushes the water flow to generate impact force, so that the impact force generated by the water flow acts on both sides of the ceramic tile, accelerating the overflow speed of the gas inside the ceramic tile and the speed of water penetrating into the ceramic tile, which helps to achieve the purpose of detecting the water absorption of the ceramic tile in a shorter time. In this process, the displacement frame 1006 moves downward from the top, and in the process of moving downward from the top to the middle position, The ceramic bricks also move downward, while the water on both sides of the ceramic bricks will move upward relative to the ceramic bricks. At the same time, the displacement plate 1003 is in a downward moving state, so that the water at the bottom of the displacement plate 1003 impacts the ceramic bricks under the guiding effect of the water guide plate 1004. At this time, the impact force generated by the hot gas blowing to both sides of the ceramic bricks to push the water flow can quickly carry the gas overflowing from the inside of the ceramic bricks away from the two sides of the ceramic bricks, and avoid the gas overflowing from the inside of the ceramic bricks to form bubbles around the ceramic bricks, thereby expanding the contact area between the water and the ceramic bricks, and improving the detection efficiency and detection accuracy. When the ceramic bricks are not moving, the displacement frame 1006 will continue to be in a downward moving state until the piston plate 1103 moves to the lowest position, and at this time the displacement plate 1003 is also in the lowest position. In this process, the gas blown out of the air jet hole 1206 will push the water flow to impact the ceramic bricks, and will act on the bottom of the ceramic bricks, and the bubbles overflowing from the bottom of the ceramic bricks and inside the ceramic bricks will be taken away from the ceramic bricks by the impact of the water flow, ensuring that all parts of the ceramic bricks are fully in contact with water. After reaching the prescribed heating time, the electric heater 8 can be turned off through the controller 3. When the displacement plate 1003 is in the middle position of the first reciprocating wire 1009 and the shaking plate 1008 and the supporting plate 905 are on the same horizontal plane, the driving motor 1001 can be turned off through the controller 3. After the ceramic tile is immersed in water and cooled to room temperature and maintained for 4±0.25h, a piece of soaked suede is wrung dry by hand and placed on the platform. The box door 2 is opened to take out each ceramic tile in turn, and the surface of each ceramic tile is gently wiped dry in turn, so that the ceramic tile does not drip water when it is tilted (and only one tile is taken out at a time, and another tile is taken out from the detection box 1 after weighing). Then, the ceramic tiles after absorbing water can be weighed in turn using the weighing scale 5, and the cleanliness of the weighing scale 5 must be ensured during each weighing, and the weighing mass of the ceramic tile after absorbing water is recorded, and then the water absorption rate of ten ceramic tiles is calculated according to the following formula, which is as follows: Water absorption rate = (weight of the ceramic brick after absorbing water - dry brick weight of the ceramic brick in its natural state) / dry brick weight of the ceramic brick in its natural state × 100%; By removing the maximum and minimum values ​​of the water absorption among the ten ceramic tiles, and then adding the water absorption of the remaining eight ceramic tiles and taking the average value, the water absorption of the ceramic tiles can be obtained, and then the valve in the drain pipe 13 can be opened by the controller 3 to discharge the water in the detection box 1.

[0031] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
