Description

Technical Field

[0001] The invention relates to the technical field of sintered brick detection, and more specifically to a device for detecting water absorption and saturation coefficient of sintered bricks. Background Art

[0002] Sintered bricks are small man-made blocks used in construction, commonly known as bricks. Sintered bricks are made of clay (including shale, coal gangue and other powders) as the main raw material, and are made through clay processing, molding, drying and baking. China created square and long bricks in the Spring and Autumn Period and the Warring States Period. During the Qin and Han Dynasties, the technology, production scale, quality and variety of bricks were significantly developed. Therefore, it has a long history of use. The water absorption rate and saturation coefficient of sintered bricks will affect the quality of bricks.

[0003] After searching, the patent with publication number CN211784922U discloses a device for detecting the water absorption rate and saturation coefficient of sintered bricks. There are four dynamometers and four storage structures, so that four groups of sintered bricks can be tested at the same time. During the whole process, the sintered bricks do not come into contact with external objects, so the accuracy of the results can be guaranteed to the greatest extent.

[0004] When the existing device tests the quality of sintered bricks through a tensile gauge to calculate the water absorption rate and the saturation coefficient, the parameters on the tensile gauge also include the storage box, so the weight of the storage box needs to be subtracted. However, when the sintered bricks are soaked, some water will be contaminated or accumulated on the outer wall and the inner bottom surface of the storage box. This part of water cannot be weighed and therefore cannot be subtracted from the reading of the tensile gauge. This will cause deviations in the data calculated subsequently, which is not conducive to the accuracy of the detection. Moreover, the storage box of the device for holding sintered bricks is always connected to the outside world during use, which will make the outside temperature and environmental conditions affect the experimental results. In addition, different areas and numbers of droppers need to be set for sintered bricks of different sizes. Therefore, it is necessary to pre-make a variety of different dropper devices and dropper installation supporting equipment, which makes it inconvenient to use and has a high cost.

[0005] In view of this, we propose a device for detecting water absorption and saturation coefficient of sintered bricks. Summary of the invention

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. A lifting plate is provided inside the cavity of the present invention. After the staff puts the sintered bricks into the storage tank, they can first insert the connecting head along the rear end of the water inlet. Under the squeezing effect of the end of the connecting head on the partition, the partition will be fixed into the bottom tank. At this time, a water pump can be used to pour external water into the cavity along the water inlet. Since the connecting head is a U-shaped structure, the water flow can flow into the bottom tank from the notch and then slowly fill the cavity. While the inside of the cavity is slowly filled with water, the lifting plate will gradually rise. After pouring in an appropriate amount of water, the staff only needs to record the scale line parameters corresponding to the top surface of the lifting plate. After the experiment is over, the water absorption rate and saturation coefficient data can be obtained by comparing the scale line parameters after the sintered bricks absorb part of the water, thereby avoiding the errors caused by weighing and improving the authenticity of the detection data.

[0019] 2. The present invention is provided with vacuum groove A, vacuum groove B and vacuum groove C. Through the design of the three, the interior of the cavity and the storage groove with sintered bricks can be wrapped in the middle. The design of these three structures can effectively isolate the influence of the external environment and the temperature conducted through the box body, and the air holes on the top surface of the box body for gas shuttle when the lifting plate is raised and lowered are also blocked by the arc filter plate. The water inlet is closed by a partition fixed by a tension spring when no connector is inserted. Through these parts, the temperature, debris and the like in the external environment can be avoided to the greatest extent to affect the water absorption of sintered bricks, which greatly improves the independence of the sintered brick test environment, further improves the accuracy of the test results, and has strong practicality.

[0020] 3. The present invention is provided with a fixing frame, a bottom plate and an extrusion block. Before the staff conducts water absorption rate and saturation coefficient test on the sintered brick, the staff can use the U-shaped handle to pull the plug plate and the fixing frame out of the storage slot, and then the sintered brick to be tested can be placed on the top surface of the bottom plate along the middle of the fixing frame. The size of the interior of the fixing frame is designed to be the same size as the size of the sintered brick. Then, in the process of inserting the fixing frame and the plug plate along the storage slot, the extrusion block will pass through the through slot and produce a lifting effect on the bottom plate through the setting of the inclined surface structure at the front end of the top surface. The bottom plate will move upward along the direction of the sliding cooperation between the slider and the slide slot as the height of the inclined surface increases, and the sintered brick will be tightly fitted with the bottom surface of the water-absorbing sponge. In this way, the sintered brick can fully absorb the moisture sucked into the water-absorbing sponge by the sponge column, and under the design of the sponge column and the water permeable hole, the water flow rate will be relatively slow, which is convenient for the absorption of the sintered brick and avoids the problem of a large amount of water leaking out at the same time and accumulating in the storage slot without time to absorb it, thereby reducing the probability of errors that may occur in the detection process and improving the reliability of the detection result.

[0021] 4. In the present invention, there is no need to change the number of sponge columns and the bearing structure of the infiltration tube. By controlling the number of shielding tubes that are easy to operate to open the water flow infiltration transmission and regulating tubes, sintered bricks of different sizes can be accurately tested, and the interlaced connection between the lifting plate and the multiple transmission and regulating tubes can also ensure stability during the up and down floating process of buoyancy.

[0034] The front end of the top face of the extrusion block is a slope structure with a low front and a high back. The outer wall of the extrusion block is in sliding contact with the inner wall of the through groove. The front end of the top face of the extrusion block is extruded and matched with the bottom surface of the bottom plate. The bottom of the lifting plate 31 is interspersed with multiple transmission and adjustment tubes in a matrix shape, and each transmission and adjustment tube is respectively sleeved on the column body of the nearest sponge column 29. A shielding tube is slidably sleeved on each transmission and adjustment tube, and multiple water inlets are arranged on the transmission and adjustment tube. The length of the shielding tube body can cover multiple water inlets at the same time, and the diameter of the transmission and adjustment tube matches the sponge column 29.

[0035] Specifically, the baffle 7 is a semi-cylindrical structure, the filter plate 8 is an arc-shaped structure with a half arc, and the two side ends of the filter plate 8 are connected and fixed to the top surface of the box body 1. Such a structure can prevent external debris from falling into the cavity through the air vent 6.

[0036] Furthermore, the outer wall of the partition 11 is in sliding contact with the inner wall of the water inlet 10, and the outer end of the tension spring 12 is connected and fixed to the inner wall of the water inlet 10, so that the water inlet 10 can be closed, and the interior of the conduit 14 located on the front side is connected to the interior of the connector 15.

[0037] Furthermore, the connector 15 is a U-shaped structure with the concave surface facing forward, the front end of the connector 15 is plugged into the water inlet 10, and the front walls on both sides of the connector 15 are squeezed into the two sides of the rear wall of the partition 11 respectively. After the staff puts the sintered bricks into the storage trough 16, they can first insert the connector 15 along the rear end of the water inlet 10. Under the squeezing effect of the end of the connector 15 on the partition 11, the partition 11 will be fixed into the bottom trough 9. At this time, the water pump 13 can be used to pour external water into the cavity 2 along the water inlet 10. Since the connector 15 is a U-shaped structure, the water flow can flow into the bottom trough 9 from the notch and then slowly fill the cavity 2. While the inside of the cavity 2 is slowly filled with water, the lifting plate 31 will also gradually rise.

[0038] Furthermore, the fixed frame 17 is slidably matched with the storage slot 16, the plug plate 18 is plugged into the plate slot 19, the outer wall of the bottom plate 22 is in sliding contact with the inner wall of the fixed frame 17, the slider 23 and the slide slot 24 are both T-shaped structures, the slider 23 is slidably matched with the slide slot 24, the front end of the top of the extrusion block 25 is a slope structure with a low front and a high back, the outer wall of the extrusion block 25 is in sliding contact with the inner wall of the through slot 26, and the front end of the top of the extrusion block 25 is squeezed and matched with the bottom surface of the bottom plate 22. Before the staff conducts water absorption and saturation coefficient testing on the sintered bricks, they can use the U-shaped handle 20 to pull the plug plate 18 and the fixed frame 17 out of the storage The storage slot 16 is provided, and then the fired brick to be tested can be placed along the middle of the fixed frame 17 on the top surface of the bottom plate 22. The size of the interior of the fixed frame 17 is designed to be the same size as the fired brick. Then, in the process of inserting the fixed frame 17 and the plug plate 18 along the storage slot 16, the extrusion block 25 will pass through the through slot 26 and produce a lifting effect on the bottom plate 22 through the setting of the inclined surface structure at the front end of its top surface. As the height of the inclined surface increases, the bottom plate 22 will move upward along the direction of the sliding cooperation between the slider 23 and the slide slot 24, and make the fired brick fit tightly against the bottom surface of the absorbent sponge 28.

[0039] It is worth mentioning that the top groove 27 is connected with the cavity 2 through the water permeable hole 30. With the design of the sponge column 29 and the water permeable hole 30, the water flow rate will be relatively slow, which is convenient for the absorption of the sintered bricks and avoids the problem of a large amount of water leaking out at the same time and accumulating in the storage tank 16 due to lack of time to absorb. The sponge column 29 is plug-in matched with the water permeable hole 30, the lifting plate 31 is slidably matched with the cavity 2, and the outer wall of the sealing ring 32 is in sliding contact with the inner wall of the cavity 2, so that the gas is prevented from leaking under the lifting plate 31 through the sealing ring 32.

[0040] Before testing the water absorption rate and saturation coefficient of the sintered bricks, the staff first adjusts the shielding tubes on the outermost circle and several inner circles of the multiple transmission adjustment tubes according to the different sizes of the sintered bricks. The shielding tubes on the outermost circle and several inner circles are slid to block all the water inlets, and the selected number of circles matches the size of the sintered bricks. The U-shaped handle 20 can be used to pull the plug plate 18 and the fixed frame 17 out of the storage slot 16, and then the sintered brick to be tested can be placed on the top surface of the bottom plate 22 along the middle of the fixed frame 17. The size of the interior of the fixed frame 17 is designed to be larger than the size of the sintered brick. Then, the sintered brick is placed in the center of the fixed frame 17, and then in the process of inserting the fixed frame 17 and the plug plate 18 along the storage slot 16, the squeeze block 25 will pass through the through groove 26 and produce a lifting effect on the bottom plate 22 through the setting of the inclined surface structure at the front end of the top surface. As the height of the inclined surface increases, the bottom plate 22 will move upward along the direction of the sliding cooperation between the slider 23 and the slide groove 24 and make the sintered brick and the bottom surface of the water-absorbing sponge 28 fit tightly. In this way, the sintered brick can fully absorb the water sucked into the water-absorbing sponge 28 by the sponge column 29. Moreover, under the design of the sponge column 29 and the water permeable hole 30, the water flow rate will be relatively slow, which is convenient for the absorption of the sintered brick and avoids the problem of a large amount of water leaking down at the same time and accumulating in the storage tank 16 without time to absorb. After the sintered brick is placed in the storage tank 16, the staff can first put the connector 15 along the water inlet 1 0 is inserted at the rear end, and under the squeezing effect of the end of the connector 15 on the partition 11, the partition 11 will be fixed into the bottom groove 9. At this time, the water pump 13 can be used to pour the external water source into the cavity 2 along the water inlet 10. Since the connector 15 is a U-shaped structure, the water flow can flow into the bottom groove 9 from the notch and then slowly fill the cavity 2. While the inside of the cavity 2 is slowly filled with water, the lifting plate 31 will gradually rise. After pouring in a proper amount of water, the staff only needs to record the scale line 3 parameters corresponding to the top surface of the lifting plate 31. After the experiment is over, the scale line 3 parameters after the sintered brick absorbs part of the water can be compared to obtain the water absorption rate and saturation coefficient data by calculation, thereby avoiding the error caused by weighing and improving the authenticity of the detection data. In addition, by The design of the vacuum groove A4, the vacuum groove B21 and the vacuum groove C33 allows the interior of the cavity 2 and the storage groove 16 where the sintered bricks are placed to be wrapped in the middle. The design of these three structures can effectively isolate the influence of the external environment and the temperature conducted through the box body 1, and the air vents 6 located on the top surface of the box body 1 for gas to shuttle when the lifting plate 31 is raised and lowered are also blocked by the arc filter plate 8. The water inlet 10 is closed by the partition 11 fixed by the tension spring 12 when there is no connector 15 inserted. Through these parts, the temperature, debris, etc. in the external environment can be avoided to the greatest extent to affect the water absorption of the sintered bricks, which greatly improves the independence of the sintered brick test environment and further improves the accuracy of the test results.

[0041] Therefore, there is no need to change the number of sponge columns and the bearing structure of the permeation tube. The sintered bricks of different sizes can be accurately tested by controlling the number of shielding tubes that are easy to operate to open the water flow permeation transmission regulating tube.
