Description

Technical Field

[0001] This utility model relates to the field of mesh belt drying oven technology, specifically to a mesh belt drying oven for drying alumina carriers. Background Technology

[0002] A mesh belt drying oven is a device that uses a steel mesh as a conveyor belt to continuously dry materials. Its working principle involves spreading the material evenly on the wire mesh belt, which is then driven back and forth inside the oven by a transmission device. Hot air flows through the material, causing the moisture in the material to evaporate, thus achieving the drying purpose. Water vapor is discharged from the exhaust vents, ensuring that the humidity inside the oven is controlled.

[0003] For example, Chinese patent document CN205138127U discloses a three-layer mesh belt hot air circulating oven. The equipment includes a frame with an oven mounted on it; the oven contains an upper conveyor belt, a middle conveyor belt, and a lower conveyor belt. The upper and middle conveyor belts are staggered and rotate in opposite directions, as are the middle and lower conveyor belts; a feed inlet is located at one end of the upper conveyor belt and a discharge outlet is located at one end of the lower conveyor belt; a fan is located above the oven and is connected to several air ducts inside the oven.

[0004] However, the above equipment also has certain defects: 1. When the above oven is in use, the material is dried through a small number of air outlets on the side of the oven and the distance between the air outlets and the conveyor belt is far, which increases the heating energy consumption of the oven and reduces the drying efficiency of the material; 2. The quality of the material produced by the oven during use depends on experience and the moisture content of the output material is unstable. Utility Model Content

[0005] This invention provides a mesh belt drying oven for drying alumina carriers, in order to solve the technical problems of low drying efficiency and unstable moisture content of materials produced by existing mesh belt drying ovens.

[0006] To solve the above problems, the present invention provides a mesh belt drying oven for drying alumina carriers, which adopts the following technical solution:

[0007] A mesh belt drying oven for drying alumina carrier includes a box body with multiple horizontally parallel conveyor belts inside the box body. The upper end of the box body has multiple exhaust ports, and one side of the upper end of the box body has a feed inlet, which is defined as the left side. The rear end of the box body has multiple horizontally arranged rectangular air conveying pipes corresponding to each conveyor belt. The front end of the air conveying pipes has a rectangular air conveying box extending forward and backward. The air conveying box is located inside the conveyor belts, and the upper end of the air conveying box has multiple air conveying holes.

[0008] Each of the left and right ends of the transmission belt has a partition that extends forward and backward and is fixed to the box body. The partition is used to improve drying efficiency.

[0009] A dew point meter is installed at the top of the chamber, which is used to detect the water vapor content inside the chamber.

[0010] Its beneficial effects are as follows: by setting up air ducts and air boxes, the material and hot air can be in full contact, reducing the heat loss of the hot air and thus improving the drying efficiency of the material; by setting up baffles, the heat exchange between the high-temperature zone in the middle of the conveyor belt and the low-temperature zone at both ends of the conveyor belt is reduced, thus reducing heat loss; by setting up dew point meters, the equipment can control the temperature and air volume of the hot air by monitoring the water vapor content in the box, thereby controlling the moisture content of the material.

[0011] Furthermore, the number of conveyor belts inside the box is four, and the conveyor belts are defined from top to bottom as the first conveyor belt, the second conveyor belt, the third conveyor belt and the fourth conveyor belt. The first conveyor belt rotates from left to right, and the adjacent conveyor belts are staggered and rotate in opposite directions.

[0012] Furthermore, the conveyor belts have shafts at both ends for driving the belts. The front ends of the left shafts of the first and third conveyor belts are equipped with drive motors, and the front ends of the right shafts of the second and fourth conveyor belts are equipped with drive motors.

[0013] Furthermore, the exhaust port is a circular tubular structure, and there are two exhaust ports. An exhaust fan is installed inside the exhaust port to accelerate the discharge of moisture from the box.

[0014] Furthermore, the lower ends of the left-side partitions of the first and third conveyor belts each have a slope that slopes from top to bottom and to the right, and the lower ends of the right-side partitions of the second and fourth conveyor belts each have a slope that slopes from top to bottom and to the left. The slopes are used to ensure that the material is evenly distributed on the conveyor belts.

[0015] Its beneficial effect is that by setting an inclined surface at the lower end of the partition, the material can be evenly distributed on the conveyor belt, thus improving the drying efficiency of the material.

[0016] Furthermore, the lower left side of the box body has a discharge port corresponding to the fourth conveyor belt.

[0017] Furthermore, the bottom of the box has multiple casters.

[0018] Its advantages are: the installation of casters at the bottom of the housing allows the equipment to be moved as needed, increasing the ease of operation.

[0019] The beneficial effects of the mesh belt drying oven for drying alumina carriers provided by this utility model are:

[0020] 1. By setting up air ducts and air boxes, the material and hot air can be in full contact, reducing the heat loss of the hot air and thus improving the drying efficiency of the material; setting up baffles reduces the heat exchange between the high-temperature zone in the middle of the conveyor belt and the low-temperature zone at both ends of the conveyor belt, reducing heat loss; setting up a dew point meter allows the equipment to control the temperature and air volume of the hot air by monitoring the water vapor content in the box, thereby controlling the moisture content of the material.

[0021] 2. By setting an inclined surface at the lower end of the partition, the material can be evenly distributed on the conveyor belt, which improves the drying efficiency of the material.

[0022] 3. Casters are installed at the bottom of the housing to allow the equipment to be moved as needed, increasing the ease of operation. Attached Figure Description

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] The main concept of this utility model is to enable the material and hot air to fully contact by setting up the air duct 3 and the air box 31, thereby reducing the heat loss of the hot air and improving the drying efficiency of the material; setting up the partition 4 reduces the heat exchange between the high temperature zone in the middle of the conveyor belt 2 and the low temperature zone at both ends of the conveyor belt 2, thereby reducing heat loss; setting up the dew point meter 6 enables the equipment to control the temperature and air volume of the hot air by monitoring the water vapor content in the box 1, thereby controlling the moisture content of the material.

[0030] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0031] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0032] Example 1 of a mesh belt drying oven for drying alumina carriers provided by this utility model:

[0033] like Figures 1 to 2 As shown, the mesh belt drying oven includes a box body 1, which is a rectangular box. The upper side of the box body 1 has a feed inlet 14, which is defined as the left side. The left end of the box body 1 has a discharge outlet 15. The upper end of the box body 1 also has two circular tubular exhaust ports 12, and an exhaust fan 13 is installed in the exhaust port 12 to accelerate the discharge of moisture from the box body 1. A dew point meter 6 is installed at the upper end of the box body 1 and between the two exhaust ports 12 to monitor the water vapor content in the box body 1. The bottom of the box body 1 has four casters 5 to allow the equipment to be moved as needed, increasing the convenience of equipment operation.

[0034] The housing 1 has four parallel horizontal conveyor belts 2 inside. The conveyor belts 2 are defined from top to bottom as the first conveyor belt 21, the second conveyor belt 22, the third conveyor belt 23, and the fourth conveyor belt 24. The first conveyor belt 21 rotates from left to right. Adjacent conveyor belts are staggered and rotate in opposite directions to transport materials alternately from top to bottom. The discharge port 15 corresponds to the left end of the fourth conveyor belt 24 to convey materials out of the housing 1. Both ends of the conveyor belts 2 have shafts 25 for driving the conveyor belts 2. The front end of the left shaft 25 of the first conveyor belt 21 and the third conveyor belt 23 is equipped with a drive motor 26. The front end of the right shaft 25 of the second conveyor belt 22 and the fourth conveyor belt 24 is equipped with a drive motor 26 to drive the conveyor belts 2 to rotate synchronously.

[0035] In addition, the rear end of the box 1 has four horizontally arranged rectangular air ducts 3 corresponding to each conveyor belt 2. The front end of the air duct 3 has a rectangular plate-shaped air box 31 extending back and forth. The air box 31 is located inside the conveyor belt 2. The upper surface of the rectangular air box 31 has multiple air holes 32. The air box 31 is used to evenly deliver the hot air conveyed by the air duct 3 to the material transported by the conveyor belt through the multiple air holes 32, which improves the drying efficiency of the material. Moreover, the air holes 32 are close to the conveyor belt, which reduces the heat loss of the hot air.

[0036] In addition, each of the left and right ends of the conveyor belts has a partition 4 extending forward and backward. The partition 4 is fixed to the front and rear sides of the housing 1. The partition 4 is used to reduce the heat exchange between the high temperature zone in the middle of the conveyor belt 2 and the low temperature zone at both ends of the conveyor belt 2, thereby reducing heat loss and improving drying efficiency. The lower end of the partition 4 at the left end of the first conveyor belt 21 and the third conveyor belt 23 has a slope 41 that slopes from top to bottom and to the right. The lower end of the partition 4 at the right end of the second conveyor belt 22 and the fourth conveyor belt 24 has a slope 41 that slopes from top to bottom and to the left. The slope 41 is used to make the material evenly distributed on the conveyor belt 2 to improve the drying efficiency of the material.

[0037] The working principle of the mesh belt drying oven is as follows: The material first falls into the left end of the first conveyor belt 21 inside the box 1 through the feed port 14. Then the material is transported to the right end of the first conveyor belt 21 and falls into the right end of the second conveyor belt 22. In this way, it is transported to the discharge port 15 through the staggered conveyor belt 2. During the movement of the material, the inclined surface 41 at the lower end of the partition 4 can push the accumulated material to make it evenly distributed on the conveyor belt 2. The dew point meter 6 at the upper end of the box 1 can monitor the water vapor content near the exhaust port 12 of the box 1. The air supply temperature and conveying speed are adjusted according to the reading of the dew point meter 6, thereby improving the drying quality of the material.

[0038] Example 2 of the mesh belt drying oven for drying alumina carrier provided by this utility model:

[0039] Its main difference from Example 1 is:

[0040] In Example 1, the dew point meter is placed between the two exhaust ports.

[0041] In this embodiment, the dew point meter is located at the right end of the housing.

[0042] Example 3 of the mesh belt drying oven for drying alumina carrier provided by this utility model:

[0043] Its main difference from Example 1 is:

[0044] In Example 1, the conveyor belt is driven by a separate drive motor.

[0045] In this embodiment, the conveyor belt is driven by a synchronous belt.
