DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

Then the blocking mechanism blocks the feed port of the drying cylinder 12 again. The heater 15 starts to work and transports hot air to the heat conduction chamber 16 through the No. 1 heat conduction pipe. The hot air dries the material inside the drying cylinder 12. At this time, the output end of the servo motor 11 drives the blocked drying cylinder 12 to rotate in both directions, and the sand sample inside the drying cylinder 12 is evenly dried. The moisture monitor inside the fixed cylinder 17 monitors the moisture content of the material inside the drying cylinder 12 in real time until the moisture content reaches the standard, and the drying of the sand sample is completed. , open the two discharge ports, cooperate with the material guide trough to unload the material inside the drying drum 12, which plays the role of drying the sand sample. The drying box 1 can be transformed and upgraded, and a weight testing system is installed at the bottom of the drying box 1.

When its weight change stabilizes and reaches a constant weight, its mass after drying is recorded, and the mass after drying is calculated according to the standard. The advantage of the material drying box based on real-time monitoring of moisture content is that it can accurately control the constant weight time, save energy consumption, reduce human interference, improve detection accuracy, automate the constant weight operation process, save labor costs, and improve work efficiency; Constant weight: refers to the situation where the interval between two consecutive weighings is not less than 3 hours, and the difference between the two masses is not greater than the weighing accuracy required by the test; At the same time, before the sand sample is dried, the output end of the electric push cylinder 13 is used to drive the sealing plate 14 to slide on the inner wall of the drying cylinder 12, and the drying space inside the drying cylinder 12 is adjusted according to the amount of sand sample to be dried, thereby reducing the waste of resources and improving the drying efficiency.

At this time, the feeding port of the drying cylinder 12 is loaded, and the sand sample enters the drying cylinder 12 along the conical surface of the blocking block 23. After the loading is completed, the feeding component is reset, and the two No. 1 elastic parts 22 pull the blocking block 23 to reset and block the feeding port of the drying cylinder 12, and start drying the sand sample in the drying cylinder 12. When the sand sample is dried, the No. 1 sealing plug 2 and the No. 2 sealing plug 21 that originally blocked the two discharge ports of the drying cylinder 12 are switched to open respectively, and the material inside the drying cylinder 12 can be discharged from the material guide trough to the bottom end of the drying box 1, which plays the role of discharging the material inside the drying cylinder 12.

[0024] The feeding assembly includes a material guide cylinder 3 and a push rod 31; the material guide cylinder 3 is slidably connected to the drying box 1 through a second elastic member, and the material guide cylinder 3 is located above the feeding port of the drying cylinder 12, and the shape of the material guide cylinder 3 is a trumpet-shaped tube; the push rod 31 is fixed to the inner wall of the material guide cylinder 3, and the bottom end of the push rod 31 protrudes from the bottom inner wall of the material guide cylinder 3; when the drying cylinder 12 is loaded, the material guide cylinder 3 is pressed to slide down the inner wall of the drying box 1, and the second elastic member is stretched and stressed, and the bottom end of the material guide cylinder 3, which was originally far away from the feeding port of the drying cylinder 12, is now in contact with the drying cylinder 12. On the cylinder 12, the push rod 31 also pushes the blocking block 23 to cooperate with the two No. 1 elastic parts 22 to slide down, thereby opening the feed port of the drying cylinder 12, and pouring the sand sample from the bell mouth of the guide cylinder 3. The sand sample enters the interior of the drying cylinder 12 along the guide cylinder 3 and the conical surface of the blocking block 23. After the loading is completed, stop pressing the guide cylinder 3, and the No. 2 elastic part drives the guide cylinder 3 and the push rod 31 to slide up and away from the drying cylinder 12. The blocking block 23 also immediately blocks the feed port of the drying cylinder 12, which plays a role in controlling the feeding and blocking the feed port of the drying cylinder 12.

[0025] like Figures 1 to 5 , Figure 7As shown, the inner wall of the drying cylinder 12 is fixedly connected with a No. 1 filter plate 4, and the blocking plate 14 is slidably connected to the No. 1 filter plate 4; the inner wall of the drying cylinder 12 is fixedly connected with a No. 2 filter plate 41 located between the No. 1 filter plate 4 and the material guide trough, and the aperture of the No. 2 filter plate 41 is smaller than the aperture of the No. 1 filter plate 4; when sampling construction sand, the sand sample taken is easily mixed with impurities such as mud or stones. The No. 1 filter plate 4 is fixed to the middle inner wall of the drying cylinder 12, and the No. 1 filter plate 4 can filter out impurities such as mud in the sand sample, and the No. 2 filter plate can filter out impurities such as mud in the sand sample. The mesh plate 41 is fixed at the lower position of the No. 1 filter plate 4, and the No. 2 filter plate 41 can filter impurities that are smaller but larger than the sand sample. As the drying cylinder 12 rotates, the impurities in the sand sample are continuously filtered by the No. 1 filter plate 4 and the No. 2 filter plate 41, thereby improving the effect of sand discharge after drying and improving the detection accuracy of the sand sample.

[0026] The outer wall of one side of the blocking plate 14 close to the No. 1 filter plate 4 is fixedly connected with a No. 1 scraper 5 and a No. 2 scraper 51 respectively; the No. 1 scraper 5 and the No. 2 scraper 51 are respectively located at the two ends of the No. 1 filter plate 4; when the drying space inside the drying cylinder 12 is adjusted, the blocking plate 14 is used to drive the No. 1 scraper 5 and the No. 2 scraper 51 to slide synchronously close to the feed port of the drying cylinder 12, and the No. 1 scraper 5 and the No. 2 scraper 51 can scrape the walls of the drying cylinder 12, the No. 1 filter plate 4 and the No. 2 filter plate 41 during the sliding process, thereby reducing impurities or material residues on the walls of the drying cylinder 12, the No. 1 filter plate 4 and the No. 2 filter plate 41, and improving the drying and filtering effects of the materials.

[0027] like Figures 1 to 6 As shown, a No. 3 filter plate 6 is fixedly connected to the inner wall of the drying cylinder 12 near the feed inlet, and the No. 3 filter plate 6 is composed of an arc filter plate and an elliptical filter plate, and the aperture of the No. 3 filter plate 6 is larger than the aperture of the No. 1 filter plate 4; a receiving plate 61 is fixedly connected to the inner wall of the drying cylinder 12 and located between the No. 1 filter plate 4 and the No. 2 filter plate 41; when filtering the sand sample entering the drying cylinder 12, the No. 3 filter plate 6 is fixed at the feed inlet of the drying cylinder 12, and the No. 3 filter plate 6 can filter the sand sample first , filter out the larger impurities in the sand sample, and temporarily store them between the No. 3 filter plate 6 and the inner wall of the drying cylinder 12. As the No. 1 filter plate 4 and the No. 2 filter plate 41 continue to filter the sand sample, the sand sample falls under the No. 2 filter plate 41. At this time, the output end of the servo motor 11 drives the drying cylinder 12 to rotate, and the sand sample at the bottom of the drying cylinder 12 is transferred to the top of the drying cylinder 12. The sand sample falls due to gravity, and the receiving plate 61 can receive part of the sand sample, reducing the re-mixing of the sand sample with the large impurities in the No. 3 filter plate 6, thereby improving the drying effect of the sand sample.

[0028] The inner wall of the No. 3 filter plate 6 is rotatably connected with a screw rod 7, and the screw rod 7 and the sealing plate 14 are connected by a screw nut pair; one end of the screw rod 7 away from the sealing plate 14 is fixedly connected to a connecting rod 71; a plurality of scrapers 72 are fixedly connected to the connecting rod 71; when part of the sand sample taken is agglomerated due to moisture, the agglomerated sand sample enters the interior of the drying cylinder 12 and is located on the No. 3 filter plate 6, and the output end of the electric push cylinder 13 is used to reciprocate and drive the sealing plate 14 to slide on the No. 1 filter plate 4, and the sealing plate 14 cooperates with the screw rod 7 and the screw nut pair to rotate the screw rod 7, and the screw rod 7 drives the plurality of scrapers 72 on the connecting rod 71 to rotate, and the plurality of scrapers 72 hit the agglomerated sand samples, thereby breaking up and filtering the agglomerated sand samples, and cooperating with the drying and filtering of the moist sand samples, thereby improving the drying effect of the agglomerated sand samples, and at the same time, the plurality of scrapers 72 scrape and sweep the material on the No. 3 filter plate 6, which can improve the material discharge and filtration speed at the No. 3 filter plate 6.

[0029] A plurality of acupuncture blocks 8 are fixedly connected to the scraper 72; the plurality of acupuncture blocks 8 are conical in shape; when dispersing agglomerated sand samples, a plurality of conical acupuncture blocks 8 are fixed on the scraper 72, and the scraper 72 acupunctures the sand sample clumps as the connecting rod 71 rotates, so that the sand sample clumps are quickly dispersed, thereby improving the effect of dispersing agglomerated sand samples.

[0030] like Figures 1 to 5 As shown, a plurality of spring pieces 9 are fixedly connected to the upper and lower surfaces of the filter plate No. 1 4; a knocking ball 91 is fixedly connected to one end of the plurality of spring pieces 9 and away from the filter plate No. 1 4; when the output end of the servo motor 11 drives the drying cylinder 12 to switch and rotate in both directions, the forward and reverse switching and rotation of the drying cylinder 12 can drive the plurality of spring pieces 9 to deform up and down, so that the plurality of knocking balls 91 continuously knock and vibrate the surfaces of the filter plate No. 3 6, the filter plate No. 1 4 and the receiving plate 61, and the vibration reduces the material residue on the surfaces of the filter plate No. 3 6, the filter plate No. 1 4 and the receiving plate 61, thereby improving the filtering and drying effects of the materials.

[0031] like Figures 1 to 7As shown, the heater 15 is fixedly connected with a No. 2 heat pipe 92, and the end of the No. 2 heat pipe 92 away from the heater 15 is rotatably connected to the screw 7, and the screw 7 can be connected to the heater 15 through the No. 2 heat pipe 92; the outer wall of the drying box 1 is respectively fixedly connected with a control box 93 and a display 94, the control box 93 is located on one side of the drying box 1, and the display 94 is located at the end of the drying box 1; when the heater 15 starts to work, hot air is transported from the two output ends into the No. 1 heat pipe and the No. 2 heat pipe. 92, the No. 1 heat conducting pipe transports hot air to the heat conducting cavity 16 to dry the material inside the drying cylinder 12, and part of the hot air is transported to the inside of the screw 7 by the No. 2 heat conducting pipe 92, and is conducted to the multiple scrapers 72, so that the multiple scrapers 72 can break up the wet and agglomerated sand samples and accelerate the drying, thereby improving the drying effect of the sand samples. The control box 93 is equipped with multiple control buttons for controlling the operation of the electrical components inside the drying box 1, and the display 94 is used to display the data monitored in real time by the moisture monitor.

[0032] Working process: Before testing the construction sand, it is necessary to sample and dry the construction sand to ensure that its moisture content meets the testing standards. First, open the sealing mechanism to seal the feed port of the drying cylinder 12, pour the sand sample from the top of the drying box 1 to the feed port of the drying cylinder 12, and then seal the feed port of the drying cylinder 12 again. The heater 15 starts to work and transports hot air to the heat conduction cavity 16 through the No. 1 heat conduction pipe. The hot air dries the material inside the drying cylinder 12. At this time, the output end of the servo motor 11 drives the blocked drying cylinder 12 to rotate in both directions, evenly drying the sand sample inside the drying cylinder 12, and the moisture monitor inside the fixed cylinder 17 monitors the drying in real time. The moisture content of the material inside the cylinder 12 is monitored until the moisture content reaches the standard and the sand sample drying is completed. The two discharge ports are opened, and the material inside the drying cylinder 12 can be discharged in cooperation with the material guide trough, thereby drying the sand sample. At the same time, before the sand sample is dried, the output end of the electric push cylinder 13 is used to drive the sealing plate 14 to slide on the inner wall of the drying cylinder 12, and the drying space inside the drying cylinder 12 is adjusted according to the amount of sand sample to be dried, thereby reducing the waste of resources and improving the drying efficiency; when the material is controlled to be loaded into the drying cylinder 12, the sealing block 23 is pushed down by the feeding assembly in cooperation with the two No. 1 elastic parts 22, and the two No. 1 elastic parts 22 are stretched and stressed, so that the sealing block 23 is away from the opening The feeding port of the drying cylinder 12 is opened.

After the loading is completed, the feeding assembly is reset, and the two No. 1 elastic members 22 pull the blocking block 23 to reset and block the feeding port of the drying cylinder 12, and the sand sample in the drying cylinder 12 is started to be dried.

On the inner wall of the drying box 1, the No. 2 elastic member is stretched and stressed, and the bottom end of the guide cylinder 3, which was originally far away from the feeding port of the drying cylinder 12, is now attached to the drying cylinder 12, and the push rod 31 also pushes the blocking block 23 to cooperate with the two No. 1 elastic members 22 to slide down, thereby opening the feeding port of the drying cylinder 12, and pouring the sand sample from the bell mouth of the guide cylinder 3. The sand sample enters the interior of the drying cylinder 12 along the conical surface of the guide cylinder 3 and the blocking block 23. After the loading is completed, stop pressing the guide cylinder 3, and the No. 2 elastic member drives the guide cylinder 3 and the push rod 31 to slide up and away from the drying cylinder 12. The blocking block 23 also immediately blocks the feeding port of the drying cylinder 12, which plays a role in controlling the feeding and blocking of the feeding port of the drying cylinder 12; When sampling construction sand, the sand samples taken are easily mixed with impurities such as mud or gravel. The No. 1 filter plate 4 is fixed on the middle inner wall of the drying cylinder 12. The No. 1 filter plate 4 can filter out impurities such as mud in the sand sample. The No. 2 filter plate 41 is fixed at the lower position of the No. 1 filter plate 4. The No. 2 filter plate 41 can filter out impurities that are smaller but larger than the sand sample. As the drying cylinder 12 rotates, the impurities in the sand sample are continuously filtered by the No. 1 filter plate 4 and the No. 2 filter plate 41, thereby improving the effect of sand discharge after drying and improving the detection accuracy of the sand sample. At the same time, the No. 1 filter plate 4 and the No. 2 filter plate 41 continuously filter the sand sample when the drying cylinder 12 rotates, so that the sand sample is filtered by the No. 1 filter plate 4 and the No. 2 filter plate The holes of 41 are dispersed, thereby improving the drying effect of the sand sample; when the drying space inside the drying cylinder 12 is adjusted, the sealing plate 14 is used to drive the No. 1 scraper 5 and the No. 2 scraper 51 to synchronously slide close to the feed port of the drying cylinder 12, and the No. 1 scraper 5 and the No. 2 scraper 51 can scrape the walls of the drying cylinder 12, the No. 1 filter plate 4 and the No. 2 filter plate 41 during the sliding process, thereby reducing impurities or material residues on the walls of the drying cylinder 12, the No. 1 filter plate 4 and the No. 2 filter plate 41, and improving the drying and filtering effect of the material; when filtering the sand sample entering the drying cylinder 12, the No. 3 filter plate 6 is fixed at the feed port of the drying cylinder 12, and the No. 3 filter plate 6 can filter the sand sample first, and then filter the sand. The larger impurities in the sample are filtered out and temporarily stored between the No. 3 filter plate 6 and the inner wall of the drying cylinder 12. As the No. 1 filter plate 4 and the No. 2 filter plate 41 continue to filter the sand sample, the sand sample falls under the No. 2 filter plate 41. At this time, the output end of the servo motor 11 drives the drying cylinder 12 to rotate, and the sand sample at the bottom of the drying cylinder 12 is transferred to the top of the drying cylinder 12. The sand sample falls due to gravity, and the receiving plate 61 can receive part of the sand sample, reducing the re-mixing of the sand sample with the large impurities in the No. 3 filter plate 6, thereby improving the drying effect of the sand sample; when part of the taken sand sample is agglomerated due to moisture, the agglomerated sand sample enters the interior of the drying cylinder 12 and is located on the No. 3 filter plate 6, and the output end of the electric push cylinder 13 is used to reciprocate and drive the blocking plate 14 Sliding on the No. 1 filter plate 4, the blocking plate 14 cooperates with the screw nut pair of the screw rod 7 to rotate the screw rod 7, and the screw rod 7 drives the multiple scrapers 72 on the connecting rod 71 to rotate. The multiple scrapers 72 hit the agglomerated sand samples, thereby breaking up and filtering the agglomerated sand samples, and drying and filtering the wet sand samples to improve the drying effect of the agglomerated sand samples. At the same time, the multiple scrapers 72 scrape the materials on the No. 3 filter plate 6, which can improve the material discharge and filtration speed at the No. 3 filter plate 6; when dispersing the agglomerated sand samples, multiple conical acupuncture blocks 8 are fixed on the scrapers 72. The scrapers 72 acupuncture the sand sample groups during the rotation of the connecting rod 71, so that the sand sample groups are quickly dispersed, thereby improving the dispersion effect of the agglomerated sand samples; When the output end of the servo motor 11 drives the drying drum 12 to switch and rotate in both directions, the switching and rotation of the drying drum 12 can drive the multiple spring pieces 9 to deform up and down, so that the multiple knocking balls 91 continuously knock and vibrate the surfaces of the No. 3 filter plate 6, the No. 1 filter plate 4 and the receiving plate 61, and the vibration reduces the material residue on the surfaces of the No. 3 filter plate 6, the No. 1 filter plate 4 and the receiving plate 61, thereby improving the filtering and drying effects of the materials; When the heater 15 starts working, hot air is transported from the two output ends into the No. 1 heat conducting pipe and the No. 2 heat conducting pipe 92 respectively. The No. 1 heat conducting pipe transports the hot air to the heat conducting cavity 16 to dry the material inside the drying cylinder 12. Part of the hot air is transported to the inside of the screw 7 by the No. 2 heat conducting pipe 92 and conducted to the multiple scrapers 72, so that the multiple scrapers 72 can break up the wet and agglomerated sand samples while accelerating the drying, thereby improving the drying effect of the sand samples. A plurality of control buttons are installed in the control box 93 for controlling the operation of the electrical components inside the drying box 1, and the display 94 is used to display the data monitored in real time by the moisture monitor.
