Description

Technical Field

[0001] This utility model relates to the technical field of drying devices, specifically a phosphogypsum floor heating drying device. Background Technology

[0002] In the field of building heating, underfloor heating systems are widely used due to their significant advantages such as comfort and energy efficiency. Phosphogypsum, as a byproduct of industrial production, is increasingly being used in the manufacture of underfloor heating panels due to its certain properties. This not only realizes the resource utilization of industrial waste but also reduces the production cost of underfloor heating panels to a certain extent. However, in the production process of phosphogypsum underfloor heating panels, the drying process has become a key factor restricting production efficiency and product quality.

[0003] Currently, existing floor heating drying devices on the market have many problems that urgently need to be solved. Most drying devices lack flexibility in design, with fixed spacing between the internal floor heating panel racks, only suitable for specific sizes of floor heating panels. When faced with floor heating panels of different sizes, these devices cannot meet the drying requirements, forcing companies to purchase multiple models of drying equipment, which undoubtedly increases production costs. In addition, after drying, existing drying devices are not convenient for removing the panels from the racks, affecting processing efficiency.

[0004] Therefore, it is necessary to modify it so that the distance between the corresponding floor heating board racks can be flexibly adjusted, making it easy to dry floor heating boards of different specifications. At the same time, after drying, the phosphogypsum floor heating boards can be pushed out, making it easy to remove the floor heating boards, improving production efficiency and reducing production costs.

[0017] like Figures 1 to 4 As shown, the present invention provides a phosphogypsum floor heating drying device, comprising a casing 1, with a heat-insulated base box 2 connected to the bottom of the casing 1, a heat-insulated outer box 3 fixedly connected to the surface of the casing 1, and several evenly distributed first electric heating plates 4 fixedly connected to the left and right sides of the inner wall of the heat-insulated outer box 3. Through slots are provided on the left and right sides of the casing 1, and heat-spreading plates 5 are fixedly connected inside the through slots. The inner sides of the first electric heating plates 4 are in contact with the surface of the heat-spreading plates 5. A hot air intake fan 6 is fixedly connected to the bottom of the casing 1, and the input end of the hot air intake fan 6 extends to the heat-insulated base box 2. Inside, several inwardly inclined and staggered second electric heating plates 7 are fixedly connected to both the left and right sides of the heat-insulated base box 2. Air inlet slots are provided on both the left and right sides of the heat-insulated base box 2. A reversible motor 8 is fixedly connected to the upper back of the casing 1 via a bracket. The output end of the reversible motor 8 extends into the interior of the casing 1 and is fixedly connected to a high-temperature resistant bidirectional lead screw 9. The front end of the high-temperature resistant bidirectional lead screw 9 is rotatably connected to the top of the inner wall of the casing 1 via a bearing seat. Symmetrically arranged high-temperature resistant nut seats 10 are threaded onto both the front and rear sides of the surface of the high-temperature resistant bidirectional lead screw 9. Both the double-acting lead screw 9 and the high-temperature resistant nut seat 10 are coated with an anti-rust coating. Each of the two high-temperature resistant nut seats 10 has a pair of support rods 11 fixedly connected to its left and right sides via connecting rods. The top and bottom ends of the support rods 11 are slidably connected to the inner wall of the housing 1. Several evenly distributed, pair-operated floor heating board placement racks 12 are fixedly connected to the inner side of the support rods 11. High-temperature resistant servo cylinders 13 are fixedly connected to the left and right sides of the bottom of the inner wall of the housing 1. A discharge push plate located inside the floor heating board placement rack 12 is fixedly connected to the top of each high-temperature resistant servo cylinder 13. A dehumidifier 15 is fixedly connected to the rear side of the frame 14 and the chassis 1. The input end of the dehumidifier 15 extends into the interior of the chassis 1. A temperature and humidity sensor is installed on the rear side of the inner wall of the chassis 1. The temperature and humidity sensor, the first electric heating plate 4, the second electric heating plate 7, the hot air intake fan 6, the forward and reverse motor 8, and the dehumidifier 15 are all electrically connected to the external controller. The temperature and humidity sensor is used to monitor the internal temperature and humidity of the chassis 1 and send signals to the external controller to control the opening or operation of the first electric heating plate 4, the second electric heating plate 7, the hot air intake fan 6, and the dehumidifier 15.

[0018] refer to Figure 2The left and right sides of the heat-insulated base box 2 are fixedly connected with mounting frames located on the surface of the air inlet slot by bolts, and a detachable high-flow air drying filter element 16 is fixedly connected inside the mounting frame.

[0019] As a technical optimization of this utility model, the high-flow-rate air drying filter element 16 can effectively filter impurities and moisture in the air entering the insulated base box 2, preventing impurities from entering the casing 1 and affecting the drying effect and damaging the equipment. At the same time, reducing the entry of moisture can avoid adverse effects on the phosphogypsum floor heating board and ensure drying quality. Moreover, the filter element is removable, which is convenient for regular replacement and cleaning, making maintenance easy, ensuring the durability of the air filtration effect, and extending the service life of the equipment.

[0020] refer to Figure 2 T-shaped blocks 17 are fixedly connected to the top and bottom of the support rod 11. T-shaped grooves 18 that cooperate with the T-shaped blocks 17 are provided on the left and right sides of the top and bottom of the inner wall of the chassis 1. The surface of the T-shaped blocks 17 is slidably connected to the inner wall of the T-shaped grooves 18.

[0021] As a technical optimization of this utility model, the T-shaped block 17 and the T-shaped groove 18 are used together, which brings good benefits. The T-shaped block 17 slides in the T-shaped groove 18, which provides a stable guiding effect for the movement of the support rod 11, making the support rod 11 more stable and smooth during the movement, avoiding swaying or deviation, thereby ensuring the accuracy and stability of the spacing adjustment of the floor heating board placement rack 12, and further ensuring the drying effect of floor heating boards of different specifications.

[0022] refer to Figure 2 Rust-proof sliding sleeves 19 are fixedly connected to both sides of the discharge push plate frame 14. Guide rods 20 are slidably connected inside the rust-proof sliding sleeves 19. The top and bottom ends of the guide rods 20 are fixedly connected to the inner wall of the machine box 1.

[0023] As a technical optimization of this utility model, the setting of rust-proof sliding sleeves 19 and guide rods 20 on the left and right sides of the discharge pusher 14 has significant beneficial effects. It provides precise guidance for the movement of the discharge pusher 14, enabling the discharge pusher 14 to accurately push out the phosphogypsum floor heating board under the drive of the high-temperature resistant servo cylinder 13, avoiding the situation of push-out deviation or jamming, and improving the efficiency and reliability of the floor heating board removal operation.

[0024] refer to Figure 2 The bottom of the inner wall of the chassis 1 is fixedly connected to a protective frame 21 located on the surface of the output end of the hot air intake fan 6 by bolts, and a protective net is fixedly connected inside the protective frame 21.

[0025] As a technical optimization of this utility model, the protective frame 21 and the protective net have important protective functions. The protective frame 21 and the protective net can prevent foreign objects from entering the hot air intake fan 6, avoid damage to the hot air intake fan 6, ensure the normal operation of the hot air intake fan 6, and thus ensure the stability of the hot air circulation system and maintain the efficient operation of the drying device. At the same time, the protective net can also prevent operators from accidentally coming into contact with the hot air intake fan 6, thus improving the safety of the equipment.

[0026] refer to Figure 1 The front of the chassis 1 is hinged to a sealed door 22. A through observation slot 23 is provided in the center of the sealed door 22. An explosion-proof transparent glass is fixed inside the observation slot 23 with sealant.

[0027] As a technical optimization of this utility model, the installation of a sealed door 22, an observation slot 23, and explosion-proof transparent glass brings about several beneficial effects. The sealed door 22 can effectively prevent heat loss inside the chassis 1, improve energy utilization efficiency, and ensure the stability of the drying environment. The observation slot 23 and explosion-proof transparent glass allow operators to observe the drying situation inside the chassis 1 without opening the door, promptly understand the drying progress and the status of the floor heating panel, and facilitate adjustments based on actual conditions.

[0028] The working principle and usage process of this utility model are as follows: First, the operator opens the sealed door 22 on the front of the casing 1. The forward and reverse motor 8 drives the high-temperature resistant bidirectional lead screw 9 to rotate, causing the high-temperature resistant nut seat 10 to move on the lead screw, which in turn moves the support rod 11. This allows for flexible adjustment of the spacing between the two mating floor heating board placement racks 12 to accommodate different specifications of phosphogypsum floor heating boards to be dried. After placing the floor heating boards alternately on the placement racks, the sealed door 22 is closed. Next, the device is started, and the first electric heating plate 4 on the inner wall of the insulated outer casing 3 begins to heat. The heat is evenly transferred to the casing 1 through the heat-dissipating plate 5 that is attached to it. The second electric heating plate 7 in the insulated bottom casing 2 heats the incoming air, and the hot air intake fan 6 sends the heated air into the casing 1, forming a hot air circulation and accelerating the drying speed of the floor heating boards. During the drying process, the temperature and humidity sensor monitors the temperature and humidity inside the casing 1 in real time and transmits the signal to the peripheral controller. The peripheral controller controls the opening or operation of the first electric heating plate 4, the second electric heating plate 7, the hot air intake fan 6, and the dehumidifier 15 according to the set value to achieve intelligent drying. At the same time, the dehumidifier 15 extracts the moisture inside the casing 1 to ensure the dryness of the drying environment. When the drying is completed, the high-temperature resistant servo cylinder 13 pushes the discharge pusher 14 to push the phosphogypsum floor heating board out of the placement rack for easy removal by the operator.
