Description

Technical Field

[0001] This invention relates to the field of concrete test block curing, and in particular to a portable concrete test block curing device. Background Technology

[0002] Concrete, as one of the most widely used materials in the construction industry, has seen its types become increasingly diverse with technological advancements, such as aerated concrete, high-performance concrete, and lightweight concrete. In addition to high strength and wear resistance, these materials also possess excellent thermal insulation properties, effectively reducing heat loss from buildings and achieving energy conservation and emission reduction. To improve safety during use, new types of concrete need to be made into test blocks and subjected to placement, curing, and testing before being put into practical application.

[0003] During the curing process of test blocks, they need to be placed in a constant temperature environment for long-term storage, such as a dedicated curing room. To improve the space utilization of the constant temperature room, a support frame for placing test blocks is also installed inside. Related technology can be found in Chinese Patent No. CN221953543U, which discloses a standard curing rack for concrete test blocks. This rack includes a base plate, a support frame above the base plate, a slide rail on the inner side of the support frame, a test block rack slidably connected to the inner side of the slide rail, a test block groove on the inner side of the test block rack, and a handle fixedly connected to one end of the test block rack. Through the cooperation of multiple structures such as the base plate, support frame, slide rail, test block rack, test block groove, slide rail, block, limiting rod, spring, and rod, the equipment can classify and store different concrete test blocks, facilitating management and making them easy to retrieve and install, thus improving work efficiency and practicality. The cooperation of multiple structures such as hydraulic telescopic rods, connecting rods, crossbars, sliders, casters, and support blocks solves the problem of inconvenient movement and the need for significant manpower in transporting test blocks, thereby improving work efficiency.

[0004] Regarding the aforementioned technologies, during the curing process of test blocks, it is necessary to maintain a water film on the outer side of the test block, and the internal environment of the curing chamber needs to be kept highly humid. For this purpose, a spraying device is usually installed in the curing chamber to regularly spray water mist to maintain the humidity of the indoor air. However, since the spraying device is usually installed directly on the upper part of the curing chamber or on the test block support, during the spraying process, the adhesive on the test block is easy to adhere to the test block support. When changing test blocks, the adhesive needs to be cleaned. Cleaning the adhesive on the inner side of the test block support is more inconvenient, affecting the convenience of the test block curing process. Summary of the Invention

[0005] To improve the convenience of the concrete test block curing process, this application provides a portable concrete test block curing device.

[0006] This application provides a portable concrete test block curing device, which adopts the following technical solution:

[0007] A portable concrete test block curing device includes a curing cylinder with an inlet and outlet on one side and a sealing door for blocking the inlet and outlet. Several temperature control components are installed on the inner wall of the curing cylinder to regulate the internal temperature. A support frame for placing the test blocks is also installed inside the curing cylinder. The support frame includes several support rings and several trays. The support rings are rotatably connected to the curing cylinder along its circumference. The curing cylinder has a rotating component for driving the support rings to rotate. All trays are located at the upper end of the support rings and are slidably connected to the support rings along their diameter. Several support rods for supporting the test blocks are fixed to the upper end of each tray. The curing cylinder is also equipped with a spray system. A water tank for supplying water to the spray system is fixed at the lower end of the curing cylinder. When the bearing ring rotates, it drives the test block through the spray range of the spray system. A collection groove is opened at the upper end of the tray. All support rods are located above the corresponding collection groove. A drain port is opened on the side of the tray near the axis of the curing cylinder. The collection groove is set at an inclination. The drain port is connected to the lower end of the collection groove. A return ring corresponding to the bearing ring is fixedly connected inside the curing cylinder. The end of the drain port away from the collection groove is located above the return ring. The return ring is used to guide the spray liquid back to the water tank. A filter for filtering the spray liquid is also provided on the side of the tray where the drain port is located.

[0008] By adopting the above technical solution, in the initial state, the sealing door blocks the inlet and outlet, the temperature control component maintains the standard curing temperature inside the curing cylinder, and the curing cylinder supports the trays via a bearing ring. When the bearing ring rotates, it moves all the trays. The test blocks are placed on the support rods of the trays, and the movement of the trays moves the test blocks. During the curing process, if spraying is required, the bearing ring is rotated via a rotating component, and the spray liquid is transported to the spraying device through the water tank. The bearing ring moves all the test blocks sequentially through the spraying area of ​​the spraying device to complete the spraying. Excess spray liquid falls into the collection tank and is discharged to the return ring through the drain port. At this time, the filter element filters the liquid, so that the return ring recovers the excess spray liquid back into the water tank. When any test block needs to be removed, the tray containing the corresponding test block is moved to the inlet / outlet via the bearing ring, the sealing door is opened, the tray is moved radially along the bearing ring, and the test block is removed. The residue on the test block remains on the tray. When cleaning the tray, any tray can be removed from the curing cylinder from the inlet / outlet, making the cleaning process more convenient and improving the convenience of the test block curing process.

[0009] Optionally, the filter element includes a filter box, a flow guide block, a movable frame, and a filter plate. The filter box is located on the side of the tray with the drain port and is slidably connected to the tray vertically. The bearing ring has a clearance opening to avoid the filter box. The filter box has an opening on the side near the tray. The flow guide block is located at the lower end of the drain port and is fixedly connected to the tray. The movable frame is located at the lower end of the flow guide block and is hinged to the tray vertically. The lower end of the movable frame extends into the filter box and is inclined towards the axis of the curing cylinder. A stop bar is fixed at the lower end of the filter box. In its natural state, the lower end of the movable frame abuts against the stop bar. A groove is vertically opened on the upper surface of the movable frame. The filter plate is placed in the groove and is located on the side of the movable frame near the stop bar. The end of the flow guide block away from the tray is located above the filter plate.

[0010] By adopting the above technical solution, in the initial state, the filter box is located inside the clearance opening, and the lower end of the movable frame is in contact with the baffle. At this time, the lower end of the movable frame is in a direction away from the axis of the curing cylinder. When the sprayed liquid passes through the drain port, it flows along the guide plate and flows towards the movable frame under the guidance of the guide plate. The upper surface of the filter plate and the inner wall of the settling tank cooperate to form a receiving chamber. The sprayed liquid enters the receiving chamber under the action of the guide plate and is filtered by the filter plate. At this time, the filtered impurities gather at the lower end of the movable frame. When cleaning the tray, the tray is moved away from the axis of the curing cylinder. At this time, the filter box is moved vertically upward and the movable frame is rotated by the baffle, so that the movable frame is gradually leveled, which facilitates the cleaning of the filter plate and improves the cleaning convenience.

[0011] Optionally, the upper end of the movable frame is provided with a baffle plate. There are two baffle plates arranged vertically. The two baffle plates are located on both sides of the movable frame along the width direction, and both baffle plates are hinged to the movable frame vertically. A straight plate is fixed on the side of the baffle plate away from the movable frame. When the lower end of the movable frame contacts the baffle rod, the straight plate is located on the side of the movable frame away from the tray, and both the baffle plate and the baffle plate abut against the upper end of the movable frame. At this time, the straight plate is in a vertical state.

[0012] By adopting the above technical solution, the baffle and the straight plate work together to improve the capacity of the upper chamber of the movable frame, further reducing the probability of the sprayed liquid overflowing from the movable frame. The baffle can be flipped, making it easy to move the baffle and the straight plate when cleaning the filter plate, thereby reducing the interference caused by the straight plate when cleaning the filter plate.

[0013] Optionally, all support rods on the same pallet are arranged parallel to each other along the width of the pallet, and the upper ends of all support rods are flush. Flat plates are fixedly connected to both sides of the pallet along the width direction. A scraper is provided between two flat plates, and the scraper is parallel to the flat plates. A sliding rod is fixed vertically between the two flat plates, and the sliding rod passes through the scraper and is slidably connected to the scraper. A cleaning port adapted to the support rod is opened at the lower end of the scraper, and the support rod passes through the cleaning port and fits against the inner wall of the cleaning port.

[0014] By adopting the above technical solution, the flat plate guides the scraper through the slide bar. In the initial state, the scraper is located on one side of the pallet along the width direction. When cleaning the pallet, the scraper moves along the width direction of the pallet, so that the scraper scrapes and cleans all the support rods through the side of the cleaning port, improving the convenience of cleaning.

[0015] Optionally, a retaining ring is fixedly connected to the inner side of the bearing ring, and a support column is coaxially fixed inside the curing cylinder. The support column passes through the retaining ring and is rotatably connected to the retaining ring. The return ring is located between the retaining ring and the bearing ring, and both the retaining ring and the bearing ring are in contact with the return ring. The retaining ring, the return ring and the bearing ring cooperate to divide the curing cylinder into several independent placement chambers. Several temperature control components are evenly distributed in several placement chambers and work independently.

[0016] By adopting the above technical solution, the curing cylinder supports the retaining ring through the support column, so that the retaining ring, the return ring and the bearing ring separate the curing cylinder. When the number of test blocks to be cured is insufficient, the test blocks can be concentrated in any independent placement chamber. At this time, the temperature control components in the other placement chambers can be turned off, thereby saving energy and reducing consumption.

[0017] Optionally, the spraying component includes two sets of spray pipe 1, spray pipe 2, mounting frame, and moving component. The mounting frame is fixedly connected to the curing cylinder. Both sets of spray pipe 1 are vertically connected to the mounting frame. When the test block moves, it passes between the two sets of spray pipe 1. Several nozzles 1 are connected to the side of the two sets of spray pipe 1 that are close to each other. Spray pipe 2 is located at the upper end of the mounting frame. The mounting frame is slidably connected to a moving block along the diameter direction of the bearing ring. The moving component is used to drive the moving block to move. Spray pipe 2 is fixedly connected to the moving block 2, and several nozzles 2 are connected to the lower end of spray pipe 2. The water tank is also connected to a liquid supply pipe for conveying spray liquid to spray pipe 1 and spray pipe 2.

[0018] By adopting the above technical solution, the liquid supply pipe delivers the liquid to the corresponding spray pipe one and spray pipe two. Under the support of the mounting frame, when the test block passes between the two spray pipes one, the spray pipe one sprays the test block along the transverse end through the nozzle one. At this time, the moving part drives the spray pipe two to move along the length of the test block, and then sprays the upper surface of the test block through the nozzle two. The spraying is more convenient.

[0019] Optionally, both ends of the second spray pipe are vertically fixed with vertical pipes along the length direction. The vertical pipes and the second spray pipe are connected and both are made of rigid material. The vertical pipes are connected to the second spray pipe, and multiple nozzles are connected to the side of the two vertical pipes that are close to each other.

[0020] By adopting the above technical solution, the liquid in the spray pipe 2 enters the vertical pipe and is sprayed out from the nozzle 3. When the spray pipe 2 moves, it drives the vertical pipe to move, so that the vertical pipe sprays the end face of the test block along the length direction through the nozzle 3, thereby further improving the spray uniformity of the test block.

[0021] Optionally, the spray pipe includes a horizontal pipe arranged in the transverse direction and a branch pipe vertically connected to the lower end of the horizontal pipe. Several nozzles are distributed along the length of the branch pipe and fixedly connected to the branch pipe. Both the horizontal pipe and the branch pipe are made of rigid material. A round rod is fixed along the length of each side of the two horizontal pipes that are far apart from each other. A drive disc corresponding to the round rod is rotatably connected to the mounting frame. A sliding rod is eccentrically rotatably connected to the side of the drive disc near the horizontal pipe. The drive disc is connected to a moving part. When the moving part is working, it drives the drive disc to rotate. A hollow limiting plate is fixed to the mounting frame. All branch pipes are located inside the limiting plate. The limiting plate has a limiting hole adapted to the nozzle. All nozzles pass through the limiting hole and contact the inner wall of the limiting hole.

[0022] By adopting the above technical solution, the spray liquid enters the horizontal pipe and flows into the branch pipe, and is sprayed out from the nozzle one through the branch pipe. The limiting plate limits the nozzle one through the limiting hole. At this time, when the moving part drives the drive disk to rotate, the drive disk drives the horizontal pipe to move synchronously through the slide rod. When the horizontal pipe moves, it causes the branch pipe and the nozzle one to shake, thereby adjusting the spray trajectory of the nozzle one and further improving the spray uniformity.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Initially, the sealing door blocks the inlet and outlet. The temperature control component maintains the standard curing temperature inside the curing cylinder. The curing cylinder supports the trays via a support ring. When the support ring rotates, it moves all the trays. The test blocks are placed on the support rods of the trays, and the movement of the trays moves the test blocks. During the curing process, if spraying is required, the rotating component drives the support ring to rotate, and the spray liquid is delivered to the spraying device through the water tank. The support ring moves all the test blocks sequentially through the spraying area of ​​the spraying device to complete the spraying. Excess spray liquid falls into the collection tank and is discharged through the drain port to the return ring. At this time, the filter element filters the liquid, allowing the return ring to collect the excess spray liquid back into the water tank. When any test block needs to be removed, the tray containing the corresponding test block is moved to the inlet / outlet via the bearing ring, the sealing door is opened, the tray is moved radially along the bearing ring, and the test block is removed. The residue on the test block remains on the tray. When cleaning the tray, any tray can be removed from the curing cylinder from the inlet / outlet, making the cleaning process more convenient and improving the convenience of the test block curing process.

[0025] 2. Initially, the filter box is located within the clearance opening, and the lower end of the movable frame is in contact with the stop bar. At this time, the lower end of the movable frame is in a direction away from the axis of the curing cylinder. When the sprayed liquid passes through the drain port, it flows along the guide plate and, guided by the guide plate, flows towards the movable frame. The upper surface of the filter plate and the inner wall of the settling tank cooperate to form a receiving chamber. The sprayed liquid enters the receiving chamber under the action of the guide plate and is filtered by the filter plate. At this time, the filtered impurities gather at the lower end of the movable frame. When cleaning the tray, the tray is moved away from the axis of the curing cylinder. At this time, the filter box is moved vertically upward, and the movable frame is rotated by the stop bar, so that the movable frame gradually flattens, which facilitates the cleaning of the filter plate and improves the convenience of cleaning.

Detailed Implementation

[0036] The present application will be further described in detail below with reference to all the accompanying drawings.

[0037] This application discloses a portable concrete test block curing device. Example

[0038] Reference Figure 1 and Figure 2 A portable concrete test block curing device includes a curing cylinder 1 with a circular cross-section. The curing cylinder 1 has an inlet and outlet 11 on one side along the lateral direction, and a sealing plate for sealing the inlet and outlet 11 is slidably connected to the outside of the curing cylinder 1.

[0039] Reference Figure 2 and Figure 3 Multiple support frames are vertically arranged inside the curing cylinder 1. Each support frame includes a support ring 21 and multiple trays 22. The support ring 21 is rotatably connected to the curing cylinder 1 along the circumference of the curing cylinder 1, and the outer circle of the support ring 21 is in contact with the inner wall of the curing cylinder 1. All trays 22 are located at the upper end of the support ring 21 and are slidably connected to the support ring 21 along the diameter direction of the support ring 21. When the support ring 21 rotates, it drives all the trays 22 to move.

[0040] Reference Figure 2 and Figure 4A hollow support column 16 is coaxially fixed inside the curing cylinder 1. A retaining ring 15 is coaxially fixed to the bearing ring 21. The retaining ring 15 is sleeved on the outside of the support column 16 and fits against the support column 16. When the bearing ring 21 rotates, it drives the retaining ring 15 to rotate. There is an annular gap between the retaining ring 15 and the bearing ring 21. The annular gap is located at the lower end of the retaining ring 15 and the bearing ring 21. A return ring 14 is provided in the annular gap. The return ring 14 is fixedly connected to the curing cylinder 1.

[0041] Reference Figure 3 and Figure 4 The curing cylinder 1 is equipped with a rotating component for driving the bearing ring 21 to rotate. This rotating component includes a rotary motor 31, a gear 33, a toothed ring 32, and a sprocket assembly 34. The toothed ring 32 is located at the lower end of the bearing ring 21 and is coaxially fixed with it. The gear 33 is rotatably connected to the curing cylinder 1 and meshes with the toothed ring 32. The rotary motor 31 is fixedly connected to the curing cylinder 1 and is located on the side of the bearing ring 21 closer to the support cylinder, thus avoiding contact with the tray 22. The sprocket assembly 34 is located between the rotary motor 31 and the gear 33. The rotary motor 31 drives the gear 33 to rotate via the sprocket, and the rotation of the gear 33 drives the toothed ring 32 to rotate, causing the bearing ring 21 to rotate.

[0042] Reference Figure 4 and Figure 5 The end of the tray 22 away from the support column 16 is slidably connected to the insertion rod in a vertical direction. The upper end face of the bearing ring 21 is provided with positioning holes corresponding to the insertion rods. When the insertion rod is inserted into the positioning hole, the displacement of the tray 22 along the diameter direction of the bearing ring 21 is restricted, thereby keeping the tray 22 stable during the rotation of the bearing ring 21.

[0043] Reference Figure 5 and Figure 6 The upper surface of the tray 22 has a collection groove 222, and the end of the tray 22 near the support column 16 has a drain port 223 communicating with the collection groove 222. The collection groove 222 is inclined from top to bottom towards the drain port 223. Multiple support rods 221 are fixedly connected to the upper part of the tray 22 along its width, with gaps between adjacent support rods 221. During curing, the sealing plate is opened, and the tray 22 at the inlet / outlet 11 is moved away from the support column 16. After placing the test block on the support rods 221 of the tray 22, the tray 22 is reset and positioned using the insert rod. The tray 22 supports the test block through the support rods 221, which helps reduce the contact area between the tray 22 and the test block, increasing the exposure area of ​​the test block to air and improving the curing efficiency of the test block.

[0044] Reference Figure 1 and Figure 2When the sealing door 12 is closed, the curing cylinder 1 is in a sealed state. Multiple temperature control components 13 are installed inside the curing cylinder 1. Operators control the temperature inside the curing cylinder 1 through these components. The temperature control components 13 are temperature controllers, which are existing technology and will not be described in detail here. Insulation plates are installed at the lower ends of the retaining ring 15, the return ring 14, and the bearing ring 21. These three components work together to vertically divide the curing cylinder 1 into multiple independent placement chambers, where the test blocks are located. The multiple temperature control components 13 are evenly distributed within the multiple placement chambers to control the temperature within each chamber. When placing a small number of test blocks, all test blocks can be placed in the same placement chamber, and the temperature control components 13 in the remaining placement chambers can be closed, thus saving energy and reducing consumption.

[0045] Reference Figure 2 and Figure 7 Each placement chamber is equipped with a spraying component 4, which includes two sets of spray pipes 41, spray pipe 42, a mounting frame 43, and a moving component 44. The mounting frame 43 is fixedly connected to the curing cylinder 1 via a support cylinder. When the bearing ring 21 rotates, it causes the test block to pass under the mounting frame 43. The mounting frame 43 is slidably connected to a moving block 431 along the diameter direction of the bearing ring 21. The spray pipe 42 is fixedly connected to the moving block 431. When the moving block 431 moves, it causes the spray pipe 42 to move. The lower end of the spray pipe 42 is connected to multiple nozzles 421 along its length. The length of the second spray pipe 42 is greater than the width of the test block, and both ends of the spray pipe along the length direction are connected to the vertical pipe 422. The vertical pipe 422 is located at the lower end of the second spray pipe 42 and is set vertically. Multiple nozzles 423 are connected to the side of the two vertical pipes 422 that are close to each other. When the second spray pipe 42 moves, it drives the two vertical pipes 422 and all the nozzles 423 to move.

[0046] Reference Figure 3 and Figure 7 A water tank 5 is installed at the lower end of the curing cylinder 1. The water tank 5 is used to store the spray liquid. A liquid supply pipe 51 is installed inside the support column 16. The liquid supply pipe 51 is connected to the second spray pipe 42. The water tank 5 supplies the spray liquid to the second spray pipe 42 through the liquid supply pipe 51. The spray liquid is sprayed out from the second nozzle 421 and the third nozzle 423 in the form of water mist. Two sets of first spray pipes 41 are located on both sides of the mounting frame 43. The first spray pipe 41 includes a horizontal pipe 412 and multiple branch pipes 413. The horizontal pipe 412 is arranged horizontally and is made of a rigid material, such as plastic or metal. There are at least two branch pipes 413. Both branch pipes 413 are vertically fixed to the lower end of the horizontal pipe 412 and are arranged vertically. When the horizontal pipe 412 moves, it drives the branch pipes 413 to move.

[0047] Reference Figure 3 and Figure 7The horizontal pipe 412 is also connected to the liquid supply pipe 51. The spray liquid in the liquid supply pipe 51 enters the horizontal pipe 412 and is then distributed to all the branch pipes 413. For the two groups of branch pipes 413 in different spray pipes 41, multiple nozzles 411 are connected to the side of the two groups of branch pipes 413 that are close to each other. When the branch pipe 413 moves, it drives the nozzles 411 to move. The spray liquid in the branch pipe 413 is sprayed out through the nozzles 411 and is also in the form of water mist.

[0048] Reference Figure 3 and Figure 7 Initially, spray pipe 42 is positioned close to any horizontal pipe 412. At this time, any test block is positioned between the two horizontal pipes 412, and water mist sprayed from nozzle 411 is applied to both ends of the test block. Mounting bracket 43 is equipped with a moving component 44 for moving the moving block 431. The moving component 44 includes a threaded rod 442 and a moving motor 441. The threaded rod 442 is positioned along the length of mounting bracket 43 and is rotatably connected to mounting bracket 43 around its own axis. The threaded rod 442 passes through the moving block 431 and is threadedly engaged with it. Under the limiting action of mounting bracket 43, the rotation of the threaded rod 442 drives the moving block 431 to move. The moving motor 441 is mounted at one end of mounting bracket 43, and its output shaft is coaxially fixed with the threaded rod 442. When the moving motor 441 operates, it drives the threaded rod 442 to rotate.

[0049] Reference Figure 3 and Figure 7 When the moving block 431 moves the second spray pipe 42, the second spray pipe 42 moves the vertical pipe 422 along the length of the test block. At this time, the water mist sprayed by the second nozzle 421 falls on the upper surface of the test block, and the water mist sprayed by the third nozzle 423 falls on both sides of the test block along the length, thereby spraying and coating each surface of the test block, which helps to improve the uniformity of spraying the test block.

[0050] Reference Figure 7 and Figure 8 The mounting bracket 43 is fixedly equipped with two limiting plates 45 corresponding to the spray pipe 41. The limiting plates 45 are hollow, and the horizontal pipe 412 and the branch pipes 413 are located inside the limiting plates 45 and are in a movable state. A limiting hole 451 is opened on the side of the two limiting plates 45 that are close to each other, and the nozzle 411 passes through the limiting hole 451. A round rod 414 is fixedly connected to the side of the two horizontal pipes 412 that are far from each other. The mounting bracket 43 is rotatably connected to a drive disk 432 corresponding to the round rod 414. The round rod 414 is eccentrically set relative to the axis of the drive disk 432, and the round rod 414 is rotatably connected to the drive disk 432. The round rod 414 is located in the middle of the horizontal pipe 412 and between the multiple branch pipes 413. The limiting plates 45 are limited by the nozzle 411, thereby restricting the horizontal pipe 412 from rotating around the round rod 414.

[0051] Reference Figure 7 and Figure 8 A pulley assembly 46 is provided between the threaded rod 442 and the drive disc 432. When the threaded rod 442 rotates, it drives the drive disc 432 to rotate via the pulley assembly 46. When the drive disc 432 rotates, it drives the horizontal tube 412 to move via the round rod 414. This causes the horizontal tube 412 to drive the nozzle 411 to move via the branch pipe 413. The limiting plate 45 limits the nozzle 411 through the limiting hole 451, causing the nozzle 411 to move circumferentially along the limiting hole 451. When the nozzle 411 moves, it changes the spraying range, thereby spraying different positions of the test block, which helps to further improve the spraying uniformity of the test block.

[0052] Reference Figure 3 and Figure 6 During the spraying process, excess spray liquid falls onto the tray 22 and enters the collection trough 222. Finally, under gravity, it is discharged from the drain port 223 into the return ring 14. The upper surface of the baffle ring 15 is inclined downwards along the axis of the support column 16, pointing outwards. The upper surface of the return ring 14 is flush with the lower end of the baffle ring 15, allowing the spray liquid falling on the baffle ring 15 to flow back into the return ring 14. The upper surface of the return ring 14 has an annular groove circumferentially formed to collect excess spray liquid. The curing cylinder 1 is equipped with a return pipe 52, and all the annular grooves are connected to the return pipe 52. The lower end of the return pipe 52 is connected to the water tank 5, allowing the spray liquid entering the annular grooves to flow back into the water tank 5 along the return pipe 52.

[0053] Reference Figure 6 and Figure 9 A filter element is provided on one side of the tray 22 with a drain port 223. The filter element includes a filter box 61, a guide block 62, a movable frame 63, and a filter plate 64. The filter box 61 is located on the side of the tray 22 near the support column 16 and is in contact with the tray 22. The filter box 61 is slidably connected to the tray 22 vertically. When the tray 22 moves, it drives the filter box 61 to move. A spring 612 is provided between the tray 22 and the filter box 61. In its natural state, the spring 612 drives the filter box 61 to the lowest end of its range of motion. The bearing ring 21 has a clearance opening 211 adapted to the filter box 61. In its natural state, the spring 612 is located in the clearance opening 211. The clearance opening 211 is inclined on the side wall away from the support column 16. When the tray 22 moves away from the support column 16, the filter box 61 contacts the side wall of the clearance opening 211 and gradually moves upward vertically.

[0054] Reference Figure 6 and Figure 9The filter box 61 has an opening on the side near the tray 22. When the filter box 61 moves vertically, the opening is always in communication with the drain port 223. The guide block 62 is located below the drain port 223 and is fixedly connected to the tray 22. The guide block 62 passes through the opening and extends into the filter box 61. The spray liquid discharged through the drain port 223 flows along the upper end of the guide block 62 towards the filter box 61.

[0055] Reference Figure 6 and Figure 9 The movable frame 63 is located at the lower end of the guide block 62, and is vertically hinged to the tray 22. When the tray 22 moves, it drives the movable frame 63 to move. In its natural state, the lower end of the movable frame 63 tilts towards the support column 16. A stop bar 611 is fixedly connected to the lower end of the filter box 61. In its natural state, the movable frame 63 abuts against the stop bar 611. When the filter box 61 moves vertically, the stop bar 611 pushes the movable frame 63 to rotate.

[0056] Reference Figure 6 and Figure 9 A settling groove 631 is opened along the thickness direction at the maximum end face of the movable frame 63. The filter plate 64 is located in the settling groove 631 and is installed on the end face of the movable frame 63 near the stop rod 611. When the movable frame 63 moves, it drives the filter plate 64 to move. The inner wall of the settling groove 631 and the upper end face of the filter plate 64 cooperate to form a receiving chamber. The spray liquid flowing along the guide plate falls into the receiving chamber after leaving the guide plate. At this time, the filter plate 64 filters the spray liquid. The impurities adhering to the test block flow with the spray liquid to the top of the filter plate 64 and gather at the lower end of the filter plate 64.

[0057] Reference Figure 6 and Figure 9 Two baffles 65 are vertically hinged to the upper end of the movable frame 63. The two baffles 65 are located on both sides of the movable frame 63. Both baffles 65 are vertically arranged, and a straight plate 651 is vertically fixed on the side of the baffle 65 away from the movable frame 63. When the movable frame 63 is in an inclined state, the sides of the straight plate 651 and the baffles 65 are in contact with the upper end surface of the movable frame 63, thereby preventing the liquid in the receiving chamber from overflowing and improving the receiving effect of the receiving chamber.

[0058] Reference Figure 6 and Figure 9A flat plate 66 is fixedly connected to both sides of the upper end of the tray 22 along the width direction. The test block is located between the two flat plates 66. A sliding rod 661 is vertically fixed between the two flat plates 66. The sliding rod 661 is located at the end of the tray 22 away from the drain port 223. A scraper 67 is provided between the two flat plates 66. The sliding rod 661 passes through the scraper 67 and is slidably connected to the scraper 67. When the tray 22 moves, the scraper 67 is moved by the flat plates 66 and the sliding rod 661. A cleaning port 671 adapted to the support rod 221 is opened at the lower end of the scraper 67. The support rod 221 passes through the cleaning port 671 and is in contact with the side wall of the cleaning port 671.

[0059] The working principle of the portable concrete test block curing device in this application embodiment is as follows: the test block is sprayed and cured in the closed space inside the curing cylinder 1 under normal conditions. After curing is completed, the test block is taken out from the inlet and outlet 11. When the tray 22 needs to be cleaned, the scraper 67 moves along the length of the support rod 221 under the guidance of the slide rod 661. The scraper 67 scrapes and cleans the support rod 221 through the side of the cleaning port 671, so that the attached material on the cleaning rod falls into the collection trough 222 under the action of gravity. At this time, spray liquid is added to the collection tank 222. The spray liquid carries solid impurities to the filter box 61. At this time, the filter plate 64 filters the spray liquid again, so that the impurities remain above the filter plate 64. The corresponding tray 22 is moved out from the inlet and outlet 11. When the tray 22 moves, the filter box 61 gradually moves upward under the guidance of the side wall of the clearance port 211. When the filter box 61 moves, the movable frame 63 is driven to gradually rotate horizontally through the stop rod 611. When the tray 22 is in a position away from the support column 16, the movable frame 63 is close to the horizontal state. At this time, the movable frame 63 drives the impurities gathered on the filter plate 64 to rotate upward, which facilitates the cleaning of the filter plate 64. The guide plate can be flipped, which helps to reduce the interference caused by the straight plate 651 during the cleaning process. When cleaning any tray 22, the corresponding tray 22 can be moved out from the curing cylinder 1 from the inlet and outlet 11. The cleaning process is relatively convenient and helps to improve the convenience of the test block curing process.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
