[0025] Example
[0026] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a building material drying device, including: a drying unit 100, a pre-crushing unit 200 and a large block material recovery unit 300.
[0027] The drying unit 100 includes a drying box 101 and a feed cover 102 fixedly installed at the center of the upper side wall of the drying box 101 and connected to the drying box 101. The upper end of the feed cover 102 is fixedly connected to a corresponding feed hopper 104, and a transparent observation window 108 is inlaid on the side wall of the drying box 101. The setting of the feed hopper 104 effectively solves the defect that the building materials are easy to spill during the feeding process. The setting of the transparent observation window 108 is convenient for the staff to intuitively observe the drying conditions of the building materials in the drying box 101. The lower side wall of the drying box 101 is slidably inserted with a corresponding collection drawer 103. The inner wall of the drying box 101 is fixedly installed with multiple sets of staggered and relative inclined feeding plates 105, and the inclined feeding plates 105 are inlaid with corresponding electric The heating column 106, the slope of each inclined feeding plate 105 is between 15 degrees and 70 degrees, and the electric heating column 106 is arranged in a mesh shape. The purpose of such arrangement is to ensure that the building materials falling on the inclined feeding plate 105 can roll down on the inclined feeding plate 105 due to their own gravity, and will not accumulate on the inclined feeding plate 105. The electric heating column 106 uses electromagnetic induction to generate eddy currents in the column to electrically heat the electric heating column 106. It converts electrical energy into electromagnetic energy, and then converts electromagnetic energy into electrical energy. The electrical energy is converted into thermal energy inside the electric heating column 106 to achieve the purpose of heating the building materials. In this practical application, it is powered by an external power supply, which belongs to a very mature existing technology, and its specific structure and working principle are not described in detail here;
[0028] Secondly, the pre-crushing unit 200 includes two groups of crushing rollers 201 rotatably mounted on the inner wall of the feed cover 102. The same end of the two crushing rollers 201 is fixedly connected to a rotating column. The rotating column penetrates the side wall of the feed cover 102 outward and is fixedly sleeved with a transmission wheel 202. The two transmission wheels 202 are connected by a transmission belt 203. A first motor 204 is fixedly mounted on one side of the feed cover 102. The output shaft of the first motor 204 penetrates the side wall of the feed cover 102 and is fixedly connected to the top of one of the crushing rollers 201.
[0029] An inclined screening net 107 is fixedly installed on the inner wall of the drying box 101, and the inclined screening net 107 is located between the inclined feeding plate 105 and the collecting drawer 103. The setting of the inclined screening net 107 can screen the building materials after drying and screen out large particles that do not meet the requirements of block building materials.
[0030] In addition, the bulk material recovery unit 300 includes a support ear 301 fixedly installed at the lower end of the side wall of one side of the drying box 101 and a hollow cylinder 302 fixedly installed at the center of the upper side wall of the support ear 301. The lower part of the inner cavity of the hollow cylinder 302 is connected to the drying box 101 through a feed channel 303, and the feed channel 303 is matched with the lower end of the inclined screening net 107. A second motor 304 is fixedly installed on the lower side wall of the support ear 301. The output shaft of the second motor 304 is inserted upward into the hollow cylinder 302 and is fixedly connected to a spiral conveying rod 305. The upper part of the inner cavity of the hollow cylinder 302 is connected to the upper part of the feed cover 102 through a return line. The collecting pipe 306 is connected, the recovery pipe 306 is tilted, and the horizontal height of the opening of one end of the recovery pipe 306 away from the feed cover 102 is higher than the horizontal height of the other end of the recovery pipe 306. The recovery pipe 306 is tilted to facilitate the large pieces of building materials in the hollow cylinder 302 to enter the feed cover 102 for secondary crushing. The upper side wall of the support ear 301 and the side wall of the drying box 101 are also fixedly connected with multiple groups of symmetrically positioned wedge-shaped reinforcement blocks 307. The setting of the wedge-shaped reinforcement blocks 307 effectively solves the defect that the connection between the support ear 301 and the side wall of the drying box 101 is prone to stress concentration and fracture.
[0031] During use, before the damp cement, sand and other building materials are put into the drying box 101 through the feed cover 102, the first motor 204 is first started, and the output shaft of the first motor 204 drives the two crushing rollers 201 to rotate through the transmission belt 203 and the transmission wheel 202 at the same time, and the crushing rollers 01 then crush the cement and sand that have solidified into blocks. The crushed cement and sand fall to the uppermost inclined feeding plate 105 under the action of their own gravity. After passing through the inclined feeding plate 105, the building materials are heated and dried by the electric heating column 106 embedded in the inclined feeding plate 105 under the action of their own gravity. This is repeated many times to ensure that the building materials are evenly and fully dried. The dried building materials are screened by the inclined screening net 107, and the building materials with particles that meet the requirements fall into the collection drawer 103. The building materials that have solidified into blocks can be pre-crushed before drying, and a plurality of offset inclined feeding plates are used to ensure that the cement, sand and other building materials are fully and evenly dried, thereby ensuring the quality of subsequent construction projects.
[0032] The large building material blocks that are too large and not completely broken after passing through the inclined screening net 107 fall into the lower part of the inner cavity of the hollow cylinder 302 through the feed channel. At this time, the second motor 304 is started, and the spiral conveying rod 305 fixedly connected thereto sends the large blocks of building materials into the inclined recovery pipe 302 and re-enters the feed cover 102 for secondary breaking and drying, ensuring that the building materials are evenly dried and that their diameter size meets the use requirements.
[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
