Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, specifically a constant temperature drying oven for building material testing. Background Technology

[0002] The foundation of construction quality lies in construction materials. If there are problems with the quality of construction materials, it will inevitably affect the construction quality. As a basic condition for the construction process, construction materials are directly involved in the construction. Therefore, the quality of construction materials will directly affect the overall quality of the construction project. Thus, the quality inspection of some construction materials requires the use of drying ovens to dry the products.

[0003] However, most existing building material testing constant temperature drying ovens cannot switch between drying and cooling of building materials. As a result, after the drying oven dries the building materials, heat remains inside. Even after waiting for the drying oven to cool down, it is still difficult for it to cool down quickly in a short time. Therefore, when the oven door is opened, the inside of the drying oven still emits heat outward, causing discomfort to the staff and making it difficult to remove the building materials from the drying oven.

[0004] Therefore, this utility model provides a constant temperature drying oven for building material testing to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0014] (III) Beneficial Effects

[0015] 1. This utility model, through the arrangement of a first cylinder, a switch door, a first rack, a first gear, a first rotating rod, a second rotating rod, a hot air blower, and a cold air blower, utilizes the first cylinder to drive the switch door downwards. When the switch door moves downwards, it drives the first rack downwards, causing the first gear meshing with the rack to drive the first rotating rod to rotate. This, in turn, causes the first rotating rod to drive the second rotating rod, which in turn positions the hot air blower below the first rotating rod, allowing the hot air blower to dry the building materials while the switch door remains closed. Once the building materials are dried, the first cylinder can drive the switch door upwards, causing the switch door to drive the first rack upwards. Using the same operating principle, this positions the cold air blower below the first rotating rod, allowing it to cool the dried building materials, making it easier for workers to retrieve them. This device can switch between drying and cooling, allowing the interior of the drying chamber to cool rapidly after drying, facilitating the removal of the building materials.

[0016] 2. This utility model, through the arrangement of a second cylinder, a second rack, and a second gear, utilizes the second cylinder to drive the second rack to move back and forth. The second gear, which meshes with the second rack, can drive the second rotating rod to swing. When the second rotating rod drives the hot air blower or cold air blower to swing, the working range of the hot air blower or cold air blower can be expanded, thereby increasing the drying or cooling speed of building materials.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a constant temperature drying oven for building material testing, such as... Figure 1-4 As shown, the drying oven includes a box body 1. A first cylinder 2 is fixedly connected to the top of the box body 1. A switch door 3 is fixedly connected to the movable end of the first cylinder 2. Two first racks 4 are fixedly connected to the back of the switch door 3. A first rotating rod 5 is rotatably connected inside the box body 1. Two first gears 6 are fixedly connected to the outer surface of the first rotating rod 5. The two first gears 6 mesh with the two first racks 4 respectively. Two second rotating rods 7 are rotatably connected to the outer surface of the first rotating rod 5. A cold air fan 8 is fixedly connected to the outer surface of one of the second rotating rods 7, and a hot air fan 9 is fixedly connected to the outer surface of the other second rotating rod 7.

[0025] When the first cylinder 2 is running, the movable end drives the opening and closing door 3 to move downwards. During this downward movement, the two first racks 4 move synchronously, causing the two first gears 6 meshing with them to drive the first rotating rod 5 to rotate. This causes the first rotating rod 5 to drive the two second rotating rods 7 that rotate in conjunction with it to rotate. One of the second rotating rods 7 then drives the hot air blower 9 to a directly downward position, allowing the outlet of the hot air blower 9 to directly face the building materials and dry them. Meanwhile, the opening and closing door 3 is closed to prevent ventilation in the chamber 1 from affecting the drying effect of the building materials. Once the building materials are dried, they can be reused... The first cylinder 2 drives the opening and closing door 3 to move upward. When the opening and closing door 3 drives the two first racks 4 to move upward, the two first gears 6 meshing with the two first racks 4 can drive the first rotating rod 5 to reverse. This causes the other second rotating rod 7, which is in sync with the first rotating rod 5, to drive the air cooler 8 to rotate to the downward position. This achieves the purpose of cooling the building materials with the air cooler 8, and indirectly maintains a constant temperature inside the box 1. The opening and closing door 3 is also in the open state, so that after the building materials have cooled down, the staff can take them out without discomfort caused by the high temperature. Thus, the opening and closing of the opening and closing door 3 is used to combine drying and cooling.

[0026] The second gear 10 is fixedly connected to the outer surface of the second rotating rod 7, and the second cylinder 11 is fixedly connected to the back of the housing 1. The second rack 12 is fixedly connected to the movable end of the second cylinder 11, and the second rack 12 meshes with the second gear 10.

[0027] When the building materials are inside the housing 1, the second cylinder 11 can be activated to drive the second rack 12 to move back and forth using its movable end. This causes one of the second gears 10 meshing with the second rack 12 to drive one of the second rotating rods 7 to swing. This allows one of the second rotating rods 7 to drive the cold air blower 8 or the hot air blower 9 to swing, thereby expanding the working range of the cold air blower 8 or the hot air blower 9, thus accelerating the drying or cooling speed of the building materials and indirectly improving the testing efficiency of the building materials.

[0028] A sealing ring 13 is fixedly connected to the back of the housing 1, and the movable end of the second cylinder 11 penetrates into the sealing ring 13.

[0029] The sealing ring 13 ensures that there is no gap at the connection between the movable end of the second cylinder 11 and the box 1, preventing the hot air blower 9 from losing temperature due to air circulation inside the box 1 when drying building materials, thereby ensuring the drying stability of the building materials.

[0030] The top of the housing 1 has a through hole 14, and the first rack 4 is located inside the through hole 14.

[0031] The through hole 14 provides space for the first rack 4 to move, preventing the first rack 4 from being blocked by the housing 1 when it moves upward with the door 3. This ensures that the first rack 4 has enough space to move upward, thereby ensuring that the air cooler 8 can be positioned directly below to cool the building materials.

[0032] A sealing box 15 is fixedly connected to the top of the box 1, and the first rack 4 and the through hole 14 are both located inside the sealing box 15.

[0033] The sealed box 15 prevents air circulation between the through hole 14 and the outside, thus preventing the drying temperature inside the box 1 from dropping due to the through hole 14. This ensures the dryness of the box 1, facilitates a better drying process for building materials, and improves the drying effect of the building materials.

[0034] A placement plate 16 is slidably connected to the bottom of the inner wall of the box 1, and a viewing window 17 is opened inside the switch door 3.

[0035] The placement plate 16 provides a place for building materials, making it easy to send the building materials into the box 1 for drying, or to pull the building materials out of the box 1. The viewing window 17 allows the staff to inspect the inside of the box 1, which facilitates the operation of the second cylinder 11 to drive the second rack 12 to mesh with one of the second gears 10, thereby expanding the working range of the hot air blower 9 or the cold air blower 8.

[0036] Working principle:

[0037] When drying building materials is required, the materials are first placed on the placement plate 16. Then, the first cylinder 2 is activated, causing the movable end of the first cylinder 2 to move the opening and closing door 3 downwards. This causes the opening and closing door 3 to move the two first racks 4 downwards simultaneously. As the two first racks 4 move downwards, the two first gears 6 meshing with them drive the first rotating rod 5 to rotate. This causes the first rotating rod 5 to drive one of the second rotating rods 7 to rotate. When the second rotating rod 7, which is in sync with the first rotating rod 5, rotates the hot air blower 9 to the lower position, the hot air blower 9 can then be dried. The vent is positioned directly below to allow the hot air blower 9 to dry the building materials. The door 3 is also in a sealed state. Once the building materials are dried, the movable end of the first cylinder 2 can be used to move the door 3 upward. When the door 3 moves the two first racks 4 upward, the second rotating rod 7 can be used to move the cold air blower 8 to a position directly below, so that the cold air blower 8 can cool the dried building materials. At the same time, the door 3 is also in an open state, making it easy for workers to take the cooled building materials.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
