Description

Technical Field

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

[0002] As one of the most widely used materials in the construction industry, concrete has become increasingly diverse with technological advancements. These include aerated concrete, high-performance concrete, and lightweight concrete. In addition to high strength and wear resistance, these concretes also offer excellent thermal insulation, effectively reducing heat loss from buildings and achieving energy conservation and emission reduction. To improve safety, new concretes must be prepared into test blocks, which must then be placed, cured, and tested before being put into practical use.

[0003] During the curing process of the test block, it is necessary to place the test block in a constant temperature environment for a long time, such as a dedicated curing room. In order to improve the space utilization rate of the constant temperature room, a bracket for placing the test block is also installed in the constant temperature room. For related technology, please refer to the Chinese patent announcement number CN221953543U, which discloses a standard curing rack for concrete test blocks, including a base plate, a bracket is arranged above the base plate, a slide rail is arranged on the inner side of the bracket, the inner side of the slide rail is slidably connected to the test block rack, the inner side of the slide rail is provided with a test block groove, and one end of the test block rack is fixedly connected to the handle. Through the coordination of multiple structures such as the base plate, the bracket, the slide rail, the test block rack, the test block groove, the slide groove, the block, the limit rod, the spring, the rod body, etc., the equipment can classify and store different concrete test blocks, which is conducive to management, convenient for taking and installing, and improves work efficiency and practicality. Through the coordination of multiple structures such as the hydraulic telescopic rod, the connecting rod, the cross bar, the slider, the universal wheel, the support block, etc., the problem of inconvenience in moving and the need to consume a lot of manpower in transporting the test pieces is solved, thereby improving work efficiency.

[0004] With regard to the above-mentioned related technologies, during the curing process of the test block, it is necessary to retain a layer of water film on the outside of the test block, and the internal environment of the curing room needs to be kept highly humid. For this reason, a spray device is usually installed in the curing room, and water mist is sprayed regularly during the curing process to maintain the humidity of the indoor gas. However, since the spray device is usually installed directly at the upper end of the curing room or on the test block holder, during the spraying process, the sticky matter on the test block is easy to adhere to the test block holder, and the sticky matter needs to be cleaned when the test block is replaced. However, for the position inside the test block holder, it is inconvenient to clean the sticky matter, which affects the convenience of the test block curing process. Summary of the Invention

[0005] In order to improve the convenience of the test block curing process, the present 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 solutions: A portable concrete test block curing device comprises a curing cylinder, an inlet and an outlet are provided on one side of the curing cylinder and a sealing door for blocking the inlet and the outlet, a plurality of temperature control components are provided on the inner wall of the curing cylinder, the temperature control components are used to adjust the temperature inside the curing cylinder, a carrying rack for placing test blocks is also provided in the curing cylinder, the carrying rack comprises a plurality of carrying rings and a plurality of trays, the plurality of carrying rings are rotatably connected to the curing cylinder along the circumference of the curing cylinder, the curing cylinder is provided with a rotating component for driving the carrying ring to rotate, all the trays are located at the upper end of the carrying ring and are slidably connected to the carrying ring along the diameter direction of the carrying ring, and a plurality of support rods for supporting the test blocks are fixed on the upper end of the tray A spray part is also provided in the curing cylinder. A water tank for supplying water to the spray part is fixedly provided at the lower end of the curing cylinder. When the carrying ring rotates, the test block is driven to pass through the spray range of the spray part. A collecting groove is provided at the upper end of the tray. All support rods are located above the corresponding collecting grooves. A drain port is provided on the side of the tray close to the axis of the curing cylinder. The collecting groove is inclined, and the drain port is connected to the lower end of the collecting groove. A reflux ring corresponding to the carrying ring is fixedly connected in the curing cylinder. The end of the drain port away from the collecting groove is located above the reflux ring. The reflux ring is used to guide the spray liquid to flow back into the water tank. A filter for filtering the spray liquid is also provided on the side of the tray where the drain port is provided.

[0007] By adopting the above technical solution, in the initial state, the sealing door blocks the inlet and outlet, the temperature control component is used to maintain the standard curing temperature in the curing tube, and the curing tube supports the tray through the support ring. When the support ring rotates, it drives all the trays to move. The test block is placed on the support rod of the tray, and the movement of the tray drives the test block to move. During the curing process, if spraying is required, the support ring is driven to rotate by the rotating part, and the spray liquid is transported to the spray part through the water tank. The support ring drives all the test blocks to pass through the spray range of the spray part in turn to complete the spraying. The excess spray liquid falls into the collecting trough and is discharged from the drain port to the return ring. At this time, the filter element filters the liquid, so that the return ring recovers the excess spray liquid into the water tank. When any test block needs to be taken out, the tray where the corresponding test block is located is moved to the inlet and outlet through the carrying ring, the sealing door is opened, the tray is moved radially along the carrying ring, and the test block is taken out. The residue on the test block remains on the tray. When cleaning the tray, any tray can be moved out of the curing cylinder from the inlet and outlet. The cleaning process is relatively convenient, which improves the convenience of the test block curing process.

[0008] Optionally, the filter element includes a filter box, a guide block, a movable frame and a filter plate. The filter box is located on one side of the tray where the drain port is opened, and the filter box is slidably connected to the tray vertically. The carrying ring is provided with a avoidance port for avoiding the filter box. The filter box is provided with an opening on one side close to the tray. The guide block is located at the lower end of the drain port and is fixedly connected to the tray. The movable plate is located at the lower end of the guide block and is hinged to the tray vertically. The lower end of the movable frame extends into the filter box and is inclined in the direction close to the axis of the maintenance barrel. A gear rod is fixed to the lower end of the filter box. In a natural state, the lower end of the movable frame abuts against the gear rod. A sink groove is opened vertically on the upper end face of the movable frame. The filter plate is arranged in the sink groove and is on the side of the movable frame close to the gear rod. The end of the guide block away from the tray is located above the filter plate.

[0009] By adopting the above technical solution, in the initial state, the filter box is located in the avoidance port, and the lower end of the movable frame contacts the stop lever. At this time, the lower end of the movable plate is in a direction away from the axis of the curing barrel. When the spray liquid passes through the discharge port, it flows along the guide plate and, guided by the guide plate, flows toward the movable frame. The upper end surface of the filter plate cooperates with the inner wall of the trough to form a holding chamber. Under the action of the guide plate, the spray liquid enters the holding chamber and is filtered by the filter plate. At this time, the filtered impurities are collected at the lower end of the movable frame. When cleaning the tray, the tray is moved away from the axis of the curing barrel. At this time, the filter box is moved vertically and the stop lever drives the movable frame to rotate, causing the movable frame to gradually level, thereby facilitating cleaning of the filter plate and improving cleaning convenience.

[0010] Optionally, a baffle is provided at the upper end of the movable frame, and two baffles are provided and arranged vertically. The two baffles are respectively located on both sides of the movable frame in the width direction, and the two baffles are vertically hinged to the movable frame. A straight plate is fixed on the side of the baffle away from the movable frame. When the lower end of the movable frame contacts the gear lever, the straight plate is located on the side of the movable frame away from the tray, and the baffle and the baffle both conflict with the upper end of the movable frame. At this time, the straight plate is in a vertical state.

[0011] By adopting the above technical solution, the baffle plate and the straight plate cooperate with each other, which is conducive to improving the accommodation effect of the accommodation chamber at the upper end of the movable frame, and further reducing the probability of the spray liquid overflowing from the movable frame. The baffle plate can be flipped, and when cleaning the filter plate, it is convenient to move the baffle plate and the straight plate, thereby reducing the interference caused by the straight plate when cleaning the filter plate.

[0012] Optionally, all support rods on the same pallet are arranged parallel to the width direction of the pallet, and the upper ends of all support rods are flush, flat plates are fixedly connected on both sides of the pallet along the width direction, a scraper is provided between the two flat plates, the scraper is parallel to the flat plates, a sliding rod is vertically fixed between the two flat plates, 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, the support rod passes through the cleaning port and fits against the inner wall of the cleaning port.

[0013] By adopting the above technical solution, the flat plate guides the scraper through the sliding rod. In the initial state, the scraper is located on one side of the pallet along the width direction. When cleaning the pallet, the scraper is moved along the width direction of the pallet so that the scraper can scrape and clean all the support rods through the side of the cleaning port, thereby improving the cleaning convenience.

[0014] Optionally, a baffle ring is fixedly connected to the inner side of the carrying ring, a support column is coaxially fixed in the curing tube, the support column passes through the baffle ring and is rotatably connected to the baffle ring, the return ring is located between the baffle ring and the carrying ring, and the baffle ring and the carrying ring are both fitted with the return ring, the baffle ring, the return ring and the carrying ring cooperate to separate the curing tube into several independent placement cavities, and several temperature control components are evenly distributed in the several placement cavities and work independently.

[0015] By adopting the above technical solution, the curing tube supports the retaining ring through the support column, so that the retaining ring, reflux ring and load-bearing ring separate the curing tube. When the number of test blocks that need to be cured is insufficient, the test blocks can be concentrated in any independent placement cavity. At this time, the temperature control components in the remaining placement cavities can be closed, thereby saving energy and reducing consumption.

[0016] Optionally, the spray component includes two groups of spray pipes 1, spray pipe 2, a mounting frame and a movable part. The mounting frame is fixedly connected to the curing tube. The two groups of spray pipes 1 are vertically connected to the mounting frame. When the test piece moves, it passes between the two groups of spray pipes 1. The two groups of spray pipes 1 are connected to a plurality of nozzles 1 on the side close to each other. Spray pipe 2 is located at the upper end of the mounting frame. The mounting frame is connected to a movable block for sliding along the diameter direction of the load-bearing ring. The movable part is used to drive the movable block to move. Spray pipe 2 is fixedly connected to movable block 2, and the lower end of spray pipe 2 is connected to a plurality of nozzles 2. The water tank is also connected to a liquid supply pipe for conveying spray liquid to spray pipe 1 and spray pipe 2.

[0017] By adopting the above technical solution, the liquid supply pipe transports the liquid to the corresponding spray pipe 1 and spray pipe 2. Under the support of the mounting frame, when the test block passes between the two spray pipes 1, the spray pipe 1 sprays the test block along the transverse end through the nozzle. At this time, the moving part drives the spray pipe 2 to move along the length direction of the test block, and then sprays the upper end surface of the test block through the nozzle 2, which is more convenient when spraying.

[0018] Optionally, vertical pipes are vertically fixed at both ends of the spray pipe 2 along the length direction. The vertical pipes are connected to the spray pipe 2 and are both made of hard material. The vertical pipes are connected to the spray pipe 2, and multiple nozzles 3 are vertically arranged on one side of the vertical pipe close to the spray pipe.

[0019] By adopting the above technical solution, the liquid in the spray pipe two enters the vertical pipe and is sprayed out from the nozzle three. When the spray pipe two moves, the vertical pipe is driven to move, so that the vertical pipe sprays the end face of the test block along the length direction through the nozzle three, further improving the spraying uniformity of the test block.

[0020] Optionally, the spray pipe includes a transversely arranged transverse pipe that is vertically connected to a branch pipe at the lower end of the transverse pipe, and a plurality of nozzles are distributed along the length direction of the branch pipe and fixedly connected to the branch pipe. The transverse pipe and the branch pipe are both made of hard material, and a round rod is fixed along the length direction on the side of the two transverse pipes that are away from each other. The mounting frame is rotatably connected to a driving disk corresponding to the round rod, and the sliding rod is eccentrically connected to the side of the driving disk close to the transverse pipe. The driving disk is connected to the moving part, and the moving part drives the driving disk to rotate when working. The mounting frame is fixed with a hollow limiting plate, and all branch pipes are located in the limiting plate. The limiting plate is provided with a limiting hole adapted to the nozzle, and all nozzles pass through the limiting hole and contact the inner wall of the limiting hole.

[0021] By adopting the above technical solution, the spraying 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 driving disk to rotate, the driving disk drives the horizontal pipe to move synchronously through the sliding rod. When the horizontal pipe moves, it drives the branch pipe and nozzle one to shake, thereby adjusting the spraying trajectory of nozzle one and further improving the spraying uniformity.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In the initial state, the sealing door blocks the inlet and outlet, and the temperature control element is used to maintain the standard curing temperature in the curing tube. The curing tube supports the tray through the support ring, and when the support ring rotates, it drives all the trays to move. The test block is placed on the support rod of the tray, and when the tray moves, it drives the test block to move. During the curing process, if spraying is required, the rotating element drives the support ring to rotate, and the spray liquid is transported to the spray element through the water tank. The support ring drives all test blocks to pass through the spray range of the spray element in turn to complete the spraying. Excess spray liquid falls into the collecting trough and is discharged from the drain port to the return ring. At this time, the filter element filters the liquid, and the return ring recovers the excess spray liquid into the water tank. When any test block needs to be taken out, the tray where the corresponding test block is located is moved to the inlet and outlet through the carrying ring, the sealing door is opened, the tray is moved radially along the carrying ring, and the test block is taken out. The residue on the test block remains on the tray. When cleaning the tray, any tray can be moved out of the curing cylinder from the inlet and outlet. The cleaning process is relatively convenient, which improves the convenience of the test block curing process. 2. In the initial state, the filter box is located in the avoidance port, and the lower end of the movable frame is in contact with the stop lever. At this time, the lower end of the movable plate is in a direction away from the axis of the curing barrel. When the spray liquid passes through the discharge port and flows along the guide plate, it flows toward the movable frame under the guidance of the guide plate. The upper end surface of the filter plate and the inner wall of the trough cooperate to form a holding chamber. Under the action of the guide plate, the spray liquid enters the holding chamber and is filtered by the filter plate. At this time, the filtered impurities are concentrated at the lower end of the movable frame. When cleaning the tray, move the tray away from the axis of the curing barrel. At this time, move the filter box vertically upward and drive the movable frame to rotate through the stop lever, so that the movable frame gradually flattens, making it easier to clean the filter plate and improving cleaning convenience.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a portable concrete test block curing device.

[0035] Example: Reference Figure 1 and Figure 2 A portable concrete specimen curing device includes a curing tube 1, the cross section of the curing tube 1 is a circular ring, an inlet and outlet 11 is opened along one side of the curing tube 1, and a sealing plate for sealing the inlet and outlet 11 is slidably connected to the outer side of the curing tube 1.

[0036] Reference Figure 2 and Figure 3 A plurality of carriers are vertically arranged inside the curing tube 1, and the carriers include a carrier ring 21 and a plurality of trays 22. The carrier ring 21 is coaxially rotatably connected to the curing tube 1 along the circumference of the curing tube 1, and the outer circle of the carrier ring 21 is in contact with the inner wall of the curing tube 1. All trays 22 are located at the upper end of the carrier ring 21 and are slidably connected to the carrier ring 21 along the diameter direction of the carrier ring 21. When the carrier ring 21 rotates, all trays 22 are driven to move.

[0037] Reference Figure 2 and Figure 4A hollow support column 16 is coaxially fixed in the curing tube 1, and a retaining ring 15 is coaxially fixed to the carrying ring 21. The retaining ring 15 is sleeved on the outside of the support column 16 and fits with the support column 16. When the carrying ring 21 rotates, it drives the retaining ring 15 to rotate, and an annular gap is left between the retaining ring 15 and the carrying ring 21. The annular gap is located at the lower end of the retaining ring 15 and the carrying ring 21. A reflux ring 14 is arranged in the annular gap, and the reflux ring 14 is fixedly connected to the curing tube 1.

[0038] Reference Figure 3 and Figure 4 The curing cylinder 1 is equipped with a rotating member for driving the carrier ring 21 to rotate. The rotating member includes a rotating 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 carrier ring 21 and is coaxially fixed with the toothed ring 32. The gear 33 is rotationally connected to the curing cylinder 1 and meshes with the toothed ring 32. The rotating motor 31 is fixedly connected to the curing cylinder 1 and is located on the side of the carrier ring 21 close to the support cylinder, thereby avoiding the tray 22. The sprocket assembly 34 is located between the rotating motor 31 and the gear 33. The rotating motor 31 drives the gear 33 to rotate via the sprocket. When the gear 33 rotates, it drives the toothed ring 32 to rotate, so that the toothed ring 32 drives the carrier ring 21 to rotate.

[0039] Reference Figure 4 and Figure 5 The end of the tray 22 away from the support column 16 is vertically slidably connected to the insertion rod, and the upper end surface of the carrying ring 21 is provided with positioning holes corresponding to the insertion rod. When the insertion rod is inserted into the positioning hole, the displacement of the tray 22 along the diameter direction of the carrying ring 21 is restricted, and the tray 22 remains stable during the rotation of the carrying ring 21.

[0040] Reference Figure 5 and Figure 6 , a collecting trough 222 is provided on the upper end surface of the tray 22, and a drainage port 223 connected to the collecting trough 222 is provided on one end of the tray 22 close to the support column 16, and the collecting trough 222 is inclined from top to bottom in the direction close to the drainage port 223. A plurality of support rods 221 are fixedly connected to the upper end of the tray 22 along the width direction, and gaps are left between adjacent support rods 221. During maintenance, the sealing plate is opened, and the tray 22 at the inlet and outlet 11 is translated in the direction away from the support column 16. After the test block is placed above the support rod 221 of the tray 22, the tray 22 is reset and positioned by inserting the rod. The tray 22 supports the test block through the support rod 221. The support rod 221 is conducive to reducing the contact area between the tray 22 and the test block, increasing the exposure area of the test block to the air, and improving the maintenance efficiency of the test block.

[0041] Reference Figure 1 and Figure 2When the sealing door 12 is closed, the curing tube 1 is in a sealed state. A plurality of temperature control components 13 are installed in the curing tube 1. The operator controls the temperature in the curing tube 1 through the temperature control components 13. The temperature control component 13 is a temperature controller, which is a prior art and will not be described in detail here. The lower ends of the retaining ring 15, the reflux ring 14 and the carrying ring 21 are all provided with insulation plates, and the three cooperate to vertically divide the curing tube 1 into a plurality of independent placement cavities, and the test blocks are all located in the placement cavities. A plurality of temperature control components 13 are evenly distributed in the plurality of placement cavities to control the temperature in the corresponding placement cavities. When placing a small number of test blocks, the test blocks can all be placed in the same placement cavity, and the temperature control components 13 in the remaining placement cavities can be closed, which is conducive to saving energy and reducing consumption.

[0042] Reference Figure 2 and Figure 7 Each placement chamber is equipped with a spray assembly 4, which includes two sets of spray pipes 1 41, spray pipe 2 42, a mounting bracket 43, and a movable member 44. The mounting bracket 43 is fixedly connected to the curing tube 1 via a support tube. When the support ring 21 rotates, the test block passes under the mounting bracket 43. The mounting bracket 43 is connected to a movable block 431 that slides along the diameter of the support ring 21. The spray pipe 2 42 is fixedly connected to the movable block 431. When the movable block 431 moves, the spray pipe 2 42 moves. The lower end of the spray pipe 2 42 is connected to multiple nozzles 2 421 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 with vertical pipes 422. The vertical pipes 422 are located at the lower end of the second spray pipe 42 and are arranged vertically. The sides of the two vertical pipes 422 close to each other are connected with multiple nozzles three 423. When the second spray pipe 42 moves, the two vertical pipes 422 and all the nozzles three 423 are driven to move.

[0043] Reference Figure 3 and Figure 7 A water tank 5 is mounted at the lower end of the curing tube 1. The water tank 5 is used to store the spray liquid. A liquid supply pipe 51 is mounted within the support column 16. The liquid supply pipe 51 is connected to the second spray pipe 42. The water tank 5 delivers the spray liquid to the second spray pipe 42 through the liquid supply pipe 51. The spray liquid is sprayed from the second nozzle 421 and the third nozzle 423 in the form of a mist. Two sets of first spray pipes 41 are located on either side 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 hard material, such as plastic or metal. There are at least two branch pipes 413. Both branch pipes 413 are fixed vertically to the lower end of the horizontal pipe 412 and are arranged vertically. When the horizontal pipe 412 moves, the branch pipes 413 move with it.

[0044] Reference Figure 3 and Figure 7Horizontal pipe 412 is also connected to liquid supply pipe 51. The spray liquid in liquid supply pipe 51 enters horizontal pipe 412 and is then distributed to all branch pipes 413. For each of the two branches 413 in different spray pipes 1 41, the adjacent sides of the two branches 413 are connected to multiple nozzles 1 411. When the branch pipes 413 move, the nozzles 1 411 also move. The spray liquid in the branch pipes 413 is sprayed out by the nozzles 1 411 in the same form of mist.

[0045] Reference Figure 3 and Figure 7 In the initial state, the spray pipe 2 42 is located near any horizontal pipe 412. At this time, any test block stays between the two horizontal pipes 412, and the water mist sprayed by the nozzle 1 411 is sprayed on both ends of the test block 1. The mounting frame 43 is equipped with a moving part 44 for driving the moving block 431 to move. The moving part 44 includes a threaded rod 442 and a moving motor 441. The threaded rod 442 is arranged along the length direction of the mounting frame 43 and is rotatably connected to the mounting frame 43 around its own axis. The threaded rod 442 passes through the moving block 431 and is threadedly engaged with the moving block 431. Under the limiting action of the mounting frame 43, the threaded rod 442 drives the moving block 431 to move when it rotates. The moving motor 441 is installed at one end of the mounting frame 43. The output shaft of the moving motor 441 is coaxially fixed with the threaded rod 442. When the moving motor 441 is working, it drives the threaded rod 442 to rotate.

[0046] Reference Figure 3 and Figure 7 When the moving block 431 drives the spray pipe 2 42 to move, the spray pipe 2 42 drives the vertical pipe 422 to move along the length direction of the test block. At this time, the water mist sprayed by the nozzle 2 421 falls on the upper end surface of the test block, and the water mist sprayed by the nozzle 3 423 falls on both sides of the test block along the length direction, thereby spraying and coating each surface of the test block, which is beneficial to improving the spraying uniformity of the test block.

[0047] Reference Figure 7 and Figure 8 The mounting frame 43 is fixed with two limit plates 45 corresponding to the spray pipe 1 41. The limit plates 45 are hollow, and the transverse pipe 412 and the branch pipe 413 are both located within the limit plates 45 and are in a movable state. A limit hole 451 is formed on the side where the two limit plates 45 are close to each other, and the nozzle 1 411 passes through the limit hole 451. A round rod 414 is fixedly connected to the side where the two transverse pipes 412 are separated from each other. The mounting frame 43 is rotatably connected to a drive disk 432 corresponding to the round rod 414. The round rod 414 is eccentrically arranged 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 transverse pipe 412 and is between the multiple branch pipes 413. The limit plates 45 are limited along with the nozzle 1 411, thereby limiting the flipping of the transverse pipe 412 around the round rod 414.

[0048] Reference Figure 7 and Figure 8 A pulley assembly 46 is provided between threaded rod 442 and drive disc 432. When threaded rod 442 rotates, pulley assembly 46 drives drive disc 432 to rotate. When drive disc 432 rotates, it drives transverse tube 412 to move via round rod 414. Transverse tube 412, through branch pipe 413, drives spray head 1 411 to move. Limiting plate 45 limits spray head 1 411 via limiting hole 451, allowing spray head 1 411 to move circumferentially along limiting hole 451. As spray head 1 411 moves, its spraying range changes, allowing different locations of test block 1 to be sprayed, which helps further improve spray uniformity on the test block.

[0049] Reference Figure 3 and Figure 6 During the spraying process, excess spray liquid falls on the tray 22 and enters the collecting tank 222, and is finally discharged from the drain port 223 to the return ring 14 under the action of gravity. The upper end face of the retaining ring 15 is tilted from top to bottom along the direction of the outer circle of the support column 16 axis, and the upper end face of the return ring 14 is flush with the lower end of the retaining ring 15, so that the spray liquid falling on the retaining ring 15 also flows to the return ring 14. An annular groove is provided on the upper end face of the return ring 14 along the circumferential direction, and the annular groove is used to collect excess spray liquid. The curing tube 1 is equipped with a return pipe 52, all of which are connected to the return pipe 52, and the lower end of the return pipe 52 is connected to the water tank 5. The spray liquid entering the annular groove flows back to the water tank 5 along the return pipe 52.

[0050] Reference Figure 6 and Figure 9 A filter element is provided on one side of the tray 22 where the drain port 223 is provided. 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 vertically slidably connected to the tray 22. When the tray 22 moves, the filter box 61 moves with it. 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 carrying ring 21 is provided with an escape opening 211 adapted to fit the filter box 61. In the natural state of the spring 612, the filter box 61 is located within the escape opening 211. The escape opening 211 is tilted away from the side wall of 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 escape opening 211 and gradually moves upward vertically.

[0051] Reference Figure 6 and Figure 9The filter box 61 has an opening on one side near the tray 22. When the filter box 61 moves vertically, the opening remains connected to the drain port 223. A guide block 62 is located below the drain port 223 and is fixedly connected to the tray 22. The guide block 62 extends through the opening and into the filter box 61. Spray liquid discharged through the drain port 223 flows along the upper end of the guide block 62 toward the filter box 61.

[0052] 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, the movable frame 63 moves with it. In its natural state, the lower end of the movable frame 63 tilts toward the support column 16. A lever 611 is fixedly connected to the lower end of the filter box 61. In its natural state, the movable frame 63 contacts the lever 611. When the filter box 61 moves vertically, the lever 611 pushes the movable frame 63 to rotate.

[0053] Reference Figure 6 and Figure 9 A trough 631 is formed along the thickness of the largest end surface of the movable frame 63. The filter plate 64 is located within the trough 631 and is mounted on the end surface of the movable frame 63 near the lever 611. Movement of the movable frame 63 drives the filter plate 64 with it. The inner wall of the trough 631 and the upper end surface of the filter plate 64 cooperate to form a receiving chamber. 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. Impurities adhering to the test block flow with the spray liquid to the top of the filter plate 64 and converge at the lower end of the filter plate 64.

[0054] 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 respectively located on both sides of the movable frame 63. The baffles 65 are all arranged vertically, and a straight plate 651 is vertically fixed to the side of the baffle 65 away from the movable plate. When the movable frame 63 is in an inclined state, the side edges of the straight plate 651 and the baffle 65 are both in contact with the upper end surface of the movable frame 63, thereby preventing the liquid in the accommodating chamber from overflowing, thereby improving the accommodating effect of the accommodating chamber.

[0055] 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 slide bar 661 is vertically fixed between the two flat plates 66. The slide bar 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 slide bar 661 passes through the scraper 67 and is slidably connected to the scraper 67. When the tray 22 moves, the flat plates 66 and the slide bar 661 drive the scraper 67 to move. A cleaning port 671 is defined at the lower end of the scraper 67 and is adapted to fit the support rod 221. The support rod 221 passes through the cleaning port 671 and is in contact with the side wall of the cleaning port 671.

[0056] The working principle of a portable concrete test block curing device in an embodiment of the present application is as follows: the sample is sprayed and cured in a closed space in the curing cylinder 1 under normal conditions. After the 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 is moved along the length direction 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 attachments on the cleaning rod fall into the collecting trough 222 under the action of gravity. At this time, spray liquid is added to the collecting trough 222, and the spray liquid drives the solid impurities to flow towards the filter box 61. At this time, the filter plate 64 filters the spray liquid again, so that the impurities stay above the filter plate 64, and 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 avoidance opening 211. When the filter box 61 moves, the gear lever 611 drives the movable frame 63 to gradually rotate horizontally. When the tray 22 is in a position away from the support column 16, the movable frame 63 is close to a horizontal state. At this time, the movable frame 63 drives the impurities gathered on the filter plate 64 to rotate upward, thereby facilitating the cleaning of the filter plate 64. The guide plate can be flipped, which is conducive to reducing 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 of the curing cylinder 1 from the inlet and outlet 11. The cleaning process is relatively convenient, which is conducive to improving the convenience of the test block curing process.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
