Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a large temperature difference waste heat recovery dryer. Background Technology

[0002] A dryer is a device that uses large temperature difference waste heat recovery to dry materials. When using a waste heat recovery dryer, a water pump sends water through the inlet pipe into the dryer body. This allows the high-temperature water to exchange heat with the material to be dried inside the cylinder, thus heating the material and facilitating its drying.

[0003] The inventors discovered in their daily work that the dryer still has at least the following problems: When using a waste heat recovery dryer, the water pump sends water through the inlet pipe into the dryer body. This allows for heat exchange between the relatively hot water and the material to be dried inside the cylinder, thus heating the material and facilitating drying. However, in actual use, it is prohibited to place the material to be dried inside the cylinder, as material near the center of the cylinder is difficult to dry, which affects the drying efficiency to some extent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a large temperature difference waste heat recovery dryer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a large temperature difference waste heat recovery dryer, comprising a dryer body, an inner cylinder of which a connecting cover is provided at both ends of the cylinder outside the dryer body, a storage tank at the top of the dryer body, an inlet pipe on one side of the storage tank, an outlet pipe at the end of the storage tank away from the inlet pipe, a water pump on the surface of both the inlet and outlet pipes, a rotating device at one end of the cylinder, a protective device at the top of the storage tank, the rotating device comprising a rotating cylinder rotatably disposed inside the cylinder, a locking block uniformly fixedly connected to the surface of the end of the rotating cylinder away from the cylinder, a motor fixedly connected to one side of the dryer body, a gear fixedly connected to the output end of the motor, and the gear and the locking block meshing with each other.

[0006] The effect achieved by the above components is as follows: When using the rotating device, the material to be dried is placed inside the cylinder, and then the material is set inside the rotating cylinder. The motor is started, and the motor drives the gear to rotate. Because the gear and the locking block mesh with each other, the rotation of the rotating cylinder inside the cylinder can be well controlled, which makes it easier to control the rolling of the material inside the rotating cylinder. This makes it easier for the material close to the inside of the rotating cylinder to be dried, thereby speeding up the drying efficiency to a certain extent.

[0007] Preferably, a fixing ring is fixedly connected inside the dryer body, and the fixing ring is sleeved in the inner wall of the rotating drum surface.

[0008] The effect achieved by the above components is that by setting the fixing ring in the inner wall of the rotating drum, the rotating drum can rotate well inside the dryer body.

[0009] Preferably, a circular groove is evenly formed on the inner wall of one end of the rotating cylinder, a circular ring is provided on the inner wall of the circular groove, a connecting plug is fixedly connected to the inner wall of the circular ring, the connecting plug is disposed inside the rotating cylinder, and a storage groove is formed on the surface of the connecting plug.

[0010] The effect achieved by the above components is that by manually sliding the connecting plug into the inside of one end of the rotating cylinder, the rubber ring is squeezed into the inside of the groove, which can prevent hot water from entering the inside of the rotating cylinder to a certain extent.

[0011] Preferably, a fixing groove is provided on one side of the inner wall of the rotating cylinder, and a locking groove is evenly provided on one side of the fixing groove. A rubber ring is slidably connected to the inner wall of the fixing groove. One end of the rubber ring is disposed inside the locking groove. The rubber ring is sleeved inside the storage groove. A first damping rod is evenly fixedly connected to one side of the inner wall of the rubber ring. The end of the first damping rod away from the rubber ring is evenly fixedly connected to one side of the inner wall of the storage groove. A first spring is sleeved on the surface of the first damping rod. One end of the first spring is fixedly connected to one side of the inner wall of the storage groove. The end of the first spring near the first damping rod is fixedly connected to the rubber ring.

[0012] The effect achieved by the above components is as follows: by pressing the rubber ring away from the receiving groove by the first spring, the end of the rubber ring away from the first damping rod is evenly set into the inside of the locking groove. This can effectively restrict the connecting plug inside one end of the rotating cylinder, so that the connecting plug can be effectively driven to rotate when the rotating cylinder rotates.

[0013] Preferably, the protective device includes a protective sleeve that is slidably fitted onto the surface of the top of the storage box.

[0014] The effect achieved by the above components is as follows: When using the protective device, the protective cover is manually placed on the surface of the storage box. Because the protective cover is made of a loose and porous material, it can play a good role in heat preservation, which can reduce the heat loss of the high-temperature water to a certain extent.

[0015] Preferably, a limiting cylinder is fixedly connected to the top of the protective sleeve, the limiting cylinder is slidably sleeved on the surface of the water inlet provided on the top of the storage tank, a fixing plug is slidably sleeved on the top of the limiting cylinder, a connecting strap is fixedly connected to one side of the fixing plug, and the end of the connecting strap away from the fixing plug is fixedly connected to one side of the limiting cylinder.

[0016] The effect achieved by the above components is as follows: after the protective cover is put on the top of the storage tank, the limiting cylinder is put on the surface of the water inlet set on the top of the storage tank, and then the fixing plug is put on the top of the limiting cylinder, so that the storage tank can be completely covered.

[0017] Preferably, a support plate is uniformly fixedly connected to the top of the dryer body. A second damping rod is fixedly connected to the side of the support plate away from the dryer body. A connecting plate is fixedly connected to the end of the second damping rod away from the support plate. A second spring is sleeved on the surface of the second damping rod. One end of the second spring is fixedly connected to one side of the support plate. The end of the second spring near the second damping rod is fixedly connected to one side of the connecting plate. A fixing rod is fixedly connected to the end of the connecting plate near the second damping rod. A locking sleeve is slidably sleeved on the surface of the fixing rod. One end of the locking sleeve is fixedly connected to one side of the protective sleeve.

[0018] The effect achieved by the above components is that the connecting plate is pulled closer to the support plate by the second spring, thereby effectively sliding the fixing rod into the inside of the locking cylinder, which can effectively restrict the protective sleeve to the surface of the storage box.

[0019] Preferably, a rubber frame is fixedly connected to the bottom of the protective sleeve, and the rubber frame is set on the top of the dryer body.

[0020] The effect achieved by the above components is that after the protective cover is placed on the surface of the storage box, the rubber frame is squeezed to the top of the dryer body, so that the rubber frame effectively seals the gap between the protective cover and the dryer body.

[0021] In this invention, by setting up a rotating device, when using the rotating device, the material to be dried is placed inside the cylinder, and then the motor is started, which drives the gear to rotate. Because the gear and the locking block mesh with each other, the rotation of the rotating cylinder inside the cylinder can be well controlled, which makes it easier to control the rolling of the material inside the rotating cylinder. This makes it easier for the material close to the inside of the rotating cylinder to be dried, thereby speeding up the drying efficiency to a certain extent. Attached Figure Description

[0027] Example 1, as Figure 1-4As shown, the large temperature difference waste heat recovery dryer has a cylinder 2 inside the dryer body 1. Both ends of the cylinder 2 outside the dryer body 1 are equipped with connecting covers 7. A storage tank 3 is installed on the top of the dryer body 1. A water inlet pipe 4 is installed on one side of the storage tank 3. A water outlet pipe 5 is installed at the end of the storage tank 3 away from the water inlet pipe 4. A water pump 6 is installed on the surface of both the water inlet pipe 4 and the water outlet pipe 5. A rotating device 8 is installed at one end of the cylinder 2. A protective device 9 is installed on the top of the storage tank 3. When using the waste heat recovery dryer, the water pump 6 introduces water into the interior of the dryer body 1 through the water inlet pipe 4. This allows for heat exchange between the relatively high temperature water and the material to be dried inside the cylinder 2, thus heating the material and facilitating its drying.

[0028] Reference Figure 2 and Figure 3The rotating device 8 includes a rotating cylinder 801, which is rotatably disposed inside the cylinder 2. A locking block 803 is uniformly fixedly connected to the surface of the rotating cylinder 801 away from the cylinder 2. A motor 813 is fixedly connected to one side of the dryer body 1. A gear 814 is fixedly connected to the output end of the motor 813. The gear 814 and the locking block 803 mesh with each other. When using the rotating device 8, the material to be dried is placed inside the cylinder 2, thus placing the material inside the rotating cylinder 801. The motor 813 is started, driving the gear 814 to rotate. Because the gear 814 and the locking block 803 mesh with each other, the rotation of the rotating cylinder 801 inside the cylinder 2 can be well controlled. The rotating drum 801 is rotated, which facilitates the control of the material's movement inside. This allows the material near the inside of the rotating drum 801 to be dried more easily, thus accelerating the drying efficiency to some extent. A fixing ring 802 is fixedly connected inside the dryer body 1. The fixing ring 802 is fitted into the inner wall of the rotating drum 801. By placing the fixing ring 802 in the inner wall of the rotating drum 801, the rotating drum 801 can rotate well inside the dryer body 1. Circular grooves 804 are evenly opened on the inner wall of one end of the rotating drum 801. A circular ring 806 is provided on the inner wall of the circular groove 804. A connecting plug 805 is fixedly connected to the inner wall of the circular ring 806 and is located inside the rotating drum 801. The surface of the connecting plug 805 has a receiving groove 807. The connecting plug 805 is manually slid into the interior of one end of the rotating cylinder 801, thereby pressing the rubber ring 806 into the circular groove 804. This can, to some extent, prevent hot water from entering the interior of the rotating cylinder 801. A fixing groove 808 is provided on one side of the inner wall of the rotating cylinder 801. A locking groove 809 is evenly provided on one side of the fixing groove 808. A rubber ring 810 is slidably connected to the inner wall of the fixing groove 808. One end of the rubber ring 810 is located inside the locking groove 809. The rubber ring 810 is fitted inside the receiving groove 807. A first damping rod 811 is evenly fixedly connected to one side of the inner wall of the rubber ring 810. The first damping rod 811 is located away from... One end of the rubber ring 810 is uniformly and fixedly connected to one side of the inner wall of the receiving groove 807. A first spring 812 is sleeved on the surface of the first damping rod 811. One end of the first spring 812 is fixedly connected to one side of the inner wall of the receiving groove 807. The end of the first spring 812 near the first damping rod 811 is fixedly connected to the rubber ring 810. By pressing the rubber ring 810 away from the receiving groove 807 through the first spring 812, the end of the rubber ring 810 away from the first damping rod 811 is uniformly set into the inside of the locking groove 809. This can effectively restrict the connecting plug 805 inside one end of the rotating cylinder 801, so that the connecting plug 805 can be effectively driven to rotate when the rotating cylinder 801 rotates.

[0029] Reference Figure 4The protective device 9 includes a protective sleeve 901, which is slidably fitted onto the top surface of the storage tank 3. When using the protective device 9, the protective sleeve 901 is manually fitted onto the surface of the storage tank 3. Because the protective sleeve 901 is a loose and porous material, it provides excellent insulation, thus reducing heat loss from the high-temperature water to a certain extent. A limiting cylinder 902 is fixedly connected to the top of the protective sleeve 901. The limiting cylinder 902 is slidably fitted onto the surface of the water inlet located on the top of the storage tank 3. A fixing plug 90 is slidably fitted onto the top of the limiting cylinder 902. 4. A connecting strap 905 is fixedly connected to one side of the fixed plug 904. The end of the connecting strap 905 away from the fixed plug 904 is fixedly connected to one side of the limiting cylinder 902. After the protective sleeve 901 is placed on the top of the storage box 3, the limiting cylinder 902 is placed on the surface of the water inlet on the top of the storage box 3. Then, the fixed plug 904 is inserted into the top of the limiting cylinder 902, which can completely cover the storage box 3. Support plates 906 are evenly fixedly connected to the top of the dryer body 1. A second damping rod 907 is fixedly connected to the side of the support plate 906 away from the dryer body 1. A connecting plate 909 is fixedly connected to the end of the second damping rod 907 away from the support plate 906. A second spring 908 is sleeved on the surface of the second damping rod 907. One end of the second spring 908 is fixedly connected to one side of the support plate 906, and the end of the second spring 908 near the second damping rod 907 is fixedly connected to one side of the connecting plate 909. A fixing rod 910 is fixedly connected to the end of the connecting plate 909 near the second damping rod 907. A locking sleeve 911 is slidably sleeved on the surface of the fixing rod 910. One end of the locking sleeve 911 is fixedly connected to one side of the protective sleeve 901. The second spring 908 pulls the connecting plate 909 closer to the support plate 906, thereby effectively sliding the fixing rod 910 into the inside of the locking cylinder 911. This effectively restricts the protective sleeve 901 to the surface of the storage box 3. A rubber frame 903 is fixedly connected to the bottom of the protective sleeve 901. The rubber frame 903 is set on the top of the dryer body 1. After the protective sleeve 901 is placed on the surface of the storage box 3, the rubber frame 903 is squeezed to the top of the dryer body 1, thus effectively blocking the gap between the protective sleeve 901 and the dryer body 1.

[0030] Working principle: When using the dryer, the water pump 6 introduces water into the dryer body 1 through the inlet pipe 4. This allows for heat exchange between the relatively hot water and the material to be dried inside the cylinder 2, thus heating the material and facilitating its drying. When using the rotating device 8, the connecting plug 805 is manually slid into one end of the rotating cylinder 801, thereby pressing the rubber ring 806 into the circular groove 804. The first spring 812 then presses the rubber ring 810 away from the receiving groove 807, thus moving the rubber ring 810 away from the first damping rod 811. One end of the connecting plug 805 is evenly positioned inside the slot 809, effectively confining it within one end of the rotating drum 801. This ensures the connecting plug 805 rotates smoothly as the drum 801 rotates, preventing hot water from entering the drum 801. The material to be dried is then placed inside the cylinder 2 and subsequently into the rotating drum 801. The motor 813 is then started, driving the gear 814 to rotate. Since the gear 814 meshes with the slot 803, and the retaining ring 802 is positioned on the surface of the rotating drum 801... The inner wall of the device is designed so that the rotating drum 801 can rotate well inside the dryer body 1, which makes it easier to control the rolling of the material inside the rotating drum 801. This facilitates the drying of the material near the inside of the rotating drum 801, thereby accelerating the drying efficiency to a certain extent. When using the protective device 9, the protective sleeve 901 is manually put on the surface of the storage box 3. After the protective sleeve 901 is put on the top of the storage box 3, the limiting cylinder 902 is put on the surface of the water inlet at the top of the storage box 3. Then, the fixing plug 904 is inserted into the top of the limiting cylinder 902, and the second spring 908 pushes the material closer to the support plate 906. Pulling the connecting plate 909 in a certain direction will slide the fixing rod 910 into the inside of the locking cylinder 911, which will effectively restrict the protective sleeve 901 to the surface of the storage box 3, thus completely enclosing the storage box 3. After the protective sleeve 901 is placed on the surface of the storage box 3, the rubber frame 903 is squeezed to the top of the dryer body 1, which will effectively block the gap between the protective sleeve 901 and the dryer body 1. Because the protective sleeve 901 is a loose and porous material, it can play a good role in heat preservation, which can reduce the heat loss of high temperature water to a certain extent.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
