Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0041] This embodiment relates to a sand drying device with block crushing, the overall structure of which is as follows: Figure 1 As shown, it includes a base 1, a heating jacket 3, and a discharge portion 4.
[0042] Among them, the base 1 is rotatably provided with a roller 2 for turning the sand, the heating sleeve 3 is sleeved on the outside of the drum 2 to heat and dry the sand in the drum 2, and the discharge part 4 is located at the outlet of the drum 2 to crush the sand into blocks after drying. The discharge part 4 is fixedly set on the base 1.
[0043] It is worth mentioning that the heating sleeve 3 is a common heating device in the prior art, which can be fixed on the drum 2 or on the base 1. It is only necessary to heat the drum 2 to dry the sand. No further details are given here. Support legs can be set at the bottom of the base 1. The support legs are not shown in the figure. The support legs can be set to have one end higher and the other end lower. Such a setting facilitates the discharge of sand from the inlet of the drum 2 to the outlet of the drum 2. After the sand is dried in the drum 2, it enters the discharge part 4. The discharge part 4 can crush the sand into blocks after drying. Such a setting can improve the production quality of concrete.
[0044] Based on the overall introduction above, an exemplary structure of the sand drying equipment with block crushing of this embodiment is as follows: Figure 3 and Figure 5 As shown, the inner wall of the inlet of the drum 2 is provided with a spiral blade 5 for conveying sand into the drum 2, and the inner wall of the drum 2 is provided with a stirring rod 6 for stirring the sand. Specifically, the spiral blade 5 is arranged at the inlet of the drum 2 to facilitate the flow of sand from the inlet of the drum 2 to the outlet of the drum 2. The stirring rod 6 can be arranged at an angle along the circumference of the drum 2 to stir the sand, improve the drying efficiency of the sand, and ensure that the sand flows to the outlet of the drum 2.
[0045] As a preferred embodiment, Figure 4 As shown, in this embodiment, the discharge portion 4 includes a cover 401 that is sleeved at the outlet of the drum 2, a discharge hole 402 opened at the outlet of the drum 2, and a nip roller 403 for crushing the agglomerated sand, with the nip roller 403 being located at the discharge hole 402. A downwardly bent support rod 404 is fixedly provided on the cover 401, and the nip roller 403 is rotatably mounted on the support rod 404, and the nip roller 403 is in contact with the inner wall of the outlet of the drum 2.
[0046] It should be noted that the cover 401 is sleeved at the outlet of the drum 2 to ensure that the sand can enter the cover 401 after being discharged from the drum 2. There are multiple discharge holes 402 along the circumference of the drum 2 to ensure that the sand can be discharged from the discharge holes 402 when passing through the discharge holes 402, and to ensure that the sand discharged from the discharge holes 402 is crushed sand. The pressing roller 403 can crush the lumped sand to ensure that it is discharged from the discharge holes 402. The support rod 404 is fixedly installed on the cover 401 to support The rod 404 can be set to be L-shaped, and one end of the support rod 404 is installed on the central axis of the cover body 401 and then extends downward. This setting can prevent the support rod 404 from blocking the flow of sand, and the pressing roller 403 can rotate on the support rod 404. Due to the setting of the support rod 404, it can ensure that the pressing roller 403 rotates at this position. The support rod 404 also ensures that the pressing roller 403 is in contact with the discharge hole 402. When the drum 2 rotates, it can drive the pressing roller 403 to rotate, thereby achieving crushing.
[0047] As a preferred Figure 4 and Figure 5 As shown, the housing 401 of this embodiment has two discharge ports 405. Crushed sand passes through the discharge hole 402 and is discharged from one of the discharge ports 405. Agglomerated sand passes through the outlet of the drum 2 and is discharged from the other discharge port 405. A baffle 406 is fixedly mounted on the housing 401 to support the drum 2. The drum 2 is inserted at the central axis of the baffle 406.
[0048] Preferably, the discharge port 405 located at the bottom of the discharge hole 402 can discharge the crushed sand from the discharge port 405. In order to avoid blockage, the uncrushed sand can be discharged from the outlet of the drum 2 and then discharged into another discharge port 405, and can be crushed again, thereby improving the drying and crushing efficiency of the sand. The purpose of setting the baffle 406 is to prevent the uncrushed sand from flowing into the discharge port 405 at the bottom of the discharge hole 402, thereby affecting the quality of the crushed sand. The baffle 406 can be welded in the cover body 401, and a circular opening is opened on the baffle 406. The outlet of the drum 2 is inserted in the circular opening. The size of the circular opening is the same as the size of the drum 2, ensuring that the crushed sand can only be discharged from the other discharge port 405 after being discharged from the outlet of the drum 2.
[0049] As a preferred Figure 1 、 Figure 2 and Figure 5 As shown, in this embodiment, the base 1 is provided with a driving component 7 for driving the drum 2 to rotate. The base 1 is rotatably provided with a roller 8 for supporting the drum 2. The drum 2 is fixedly provided with a support ring 9 that abuts against the roller 8. Specifically, the driving component 7 is mounted on the base 1 to ensure the rotation of the drum 2. The rollers 8 are mounted on both sides of the drum 2. The support ring 9 and the drum 2 are coaxial. The support ring 9 is placed on the drum 2. When the drum 2 rotates, the rollers 8 can rotate with it. This arrangement can reduce friction. The rollers 8 are also provided on both sides of the support ring 9. The rollers 8 are mounted on the base 1. The rollers 8 can ensure that the drum 2 can only rotate and will not deviate from the direction.
[0050] As a preferred embodiment, Figure 2 As shown, in this embodiment, the driving component 7 includes a motor 701 fixedly arranged on the base 1, a ring gear 702 fixedly arranged on the drum 2, and a gear 703 meshing with the ring gear 702 and fixed to the driving end of the motor 701, and support blocks 704 are respectively provided on the ring gear 702 and the support ring 9, and the support block 704 is installed on the drum 2.
[0051] It should be noted that the motor 701 is installed on the base 1 and is used in conjunction with the reducer. The gear 703 is installed on the drive shaft of the reducer. The rotation of the motor 701 can drive the gear 703 to rotate. The gear 703 and the ring gear 702 are engaged, so the ring gear 702 can be driven to rotate. Since the ring gear 702 and the roller 2 are coaxially arranged, the roller 2 can rotate on the roller 8. The purpose of arranging support blocks 704 on the support ring 9 and the ring gear 702 is to facilitate the installation of the support ring 9 and the ring gear 702. Multiple groups of support blocks 704 are arranged circumferentially on the roller 2 to ensure uniform force on the support ring 9 and the ring gear 702.
[0052] The sand drying equipment with agglomerate crushing in this embodiment heats and dries the sand in the drum 2 through the heating sleeve 3, thereby improving the drying efficiency; the setting of the discharge part 4 effectively crushes the dried agglomerated sand, thereby improving the grinding effect; the setting of the spiral blades 5 and the stirring rod 6 improves the turning and stirring efficiency of the sand in the drum 2, thereby achieving a more uniform drying effect; the setting of the two discharge ports 405 effectively separates the crushed sand and the agglomerated sand, thereby improving the quality and stability of the product.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
