Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically a refrigerated dryer for processing rolled products of ferrous metal smelting. Background Technology

[0002] In the field of ferrous metal smelting and rolling processing, steel often retains moisture on its surface after undergoing processes such as hot rolling, cold rolling, pickling or cooling. If this moisture is not removed in a timely and effective manner, it will directly affect the quality of subsequent processes and products. According to CN116518652A, a refrigerated dryer for electronic toy processing is disclosed. This technology discloses a technical solution including "a dryer body, a box fixedly connected to the top of the dryer body's inner cavity, support plates fixedly connected to the bottom of both sides of the box's inner cavity, a cold air fan fixedly installed on one side of the top of the support plate, and an air outlet pipe fixedly connected to the bottom of the cold air fan". It has the following technical effects: "by adding a support structure, it is easier to support the equipment, preventing displacement of the equipment due to shaking pressure during operation, thus improving the stability of the equipment and solving the problem of workers' inconvenience; by adding a filter structure, it is easier to filter the gas, ensuring air quality and improving the practicality of the equipment, meeting the needs of workers; by adding a refrigeration structure, it is easier to cool down the electronic toys, improving the efficiency of electronic toy production and saving workers' time". In the existing drying process of ferrous metal rolled products, most equipment adopts a fixed blowing structure, and the airflow coverage and direction cannot be adjusted. When processing workpieces with complex curved surfaces or concave and convex structures, the fixed airflow is difficult to effectively reach the concave areas or the leeward side, resulting in local areas of the workpiece surface not being fully swept away, thus causing the problem of moisture residue. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a refrigerated dryer for processing ferrous metal smelting and rolling products. Through a dynamic, full-coverage blowing method, it breaks the limitations of fixed direct airflow distribution, effectively handling complex geometric structures such as grooves and welds on the workpiece surface, achieving uniform drying without dead angles, preventing local water accumulation and drying blind spots, and improving the uniformity and reliability of the drying process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a refrigerated dryer for processing ferrous metal smelting rolled products, comprising a dryer for drying ferrous metal smelting rolled products, the dryer comprising: The main components include a partition fixed in the middle of the chassis and used to divide the interior of the chassis into two spaces, left and right. The blower assembly includes side plates fixed to the left and right ends inside the chassis. Inside the chassis, there are three blower pipes arranged front and back. The three blower pipes form a group, and several groups are arranged in a vertical array. The two ends of the blower pipes are rotatably installed with the side plates at both ends. Several blower heads are fixed on the blower pipes and arranged equidistantly. An active swing arm is fixed to the outer wall of the right end of one of the blower pipes. A connecting rod is pivotally connected to the other end of the active swing arm. A motor is installed on the outer wall of the chassis. A rotating arm is fixed to the output end of the motor, and the other end of the rotating arm is pivotally connected to the end of the connecting rod away from the active swing arm.

[0005] Preferably, the blower assembly further includes a driven swing arm fixed to the outer wall of the left end of the blower tube, and the driven swing arms on the three blower tubes arranged in the front and rear are pivotally connected to the same transverse connecting rod.

[0006] Preferably, the blower assembly further includes a single longitudinal link pivotally connected between several transverse links.

[0007] Preferably, the blower assembly further includes a rotary joint installed at the right end of the blower pipe, and the rotary joints on the three blower pipes arranged in the front and rear are connected by the same air supply pipe, and the air supply pipes are connected by the same air supply pipe.

[0008] Preferably, the main component also includes doors installed on both sides of the front end of the chassis, a refrigeration system is installed at the lower end of the chassis, and the lower end of the air supply duct is connected to the refrigeration system, and an air exchange system is installed at the upper end of the chassis.

[0009] Preferably, the dryer further includes several brackets fixed to the inner wall of the side plate and arranged vertically, with trays placed on the brackets.

[0010] Beneficial effects This utility model provides a refrigerated dryer for processing rolled products in ferrous metal smelting. Compared with the prior art, it has the following advantages: 1. Driven by a single motor, multiple sets of air blowers are coordinated and oscillate in unison. The motor's power is transmitted to an active air blower via a rotating arm, connecting rod, and active swing arm. The movement of this active air blower is then synchronously transmitted to the other two air blowers in the same group via the driven swing arm at its left end and the transverse connecting rod, ensuring a uniform airflow sweeping pattern across the width of the workpiece. Furthermore, the longitudinal connecting rod links all the vertically distributed groups together, allowing air blowers in different layers to oscillate synchronously. Through a dynamic, full-coverage blowing method, the limitations of fixed direct blowing airflow distribution are broken, effectively handling complex geometric structures such as grooves and welds on the workpiece surface. This achieves uniform drying without dead angles, prevents local water accumulation and drying blind spots, and improves the uniformity and reliability of the drying process.

[0011] 2. The refrigeration system, as the core of the drying process, continuously generates low-temperature, low-dew-point dry air through a refrigeration cycle. This air is then stably delivered to all the oscillating air ducts via a supply network consisting of air supply pipes, delivery pipes, and rotary joints, ensuring the drying quality of the purge airflow from the source. The layered trays and their corresponding air duct groups above form independent drying units, enabling the equipment to perform large-scale, high-efficiency layered processing simultaneously. Meanwhile, the ventilation system located at the top of the chamber continuously forces out the water vapor generated by the evaporation of the workpieces, working in conjunction with the refrigeration system to maintain a stable low-humidity environment within the chamber.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a refrigerated dryer for processing ferrous metal smelting rolled products, including a dryer 1 and used for drying ferrous metal smelting rolled products, the dryer 1 including: The main component 11 includes a partition 112 fixed in the middle inside the chassis 111 and is used to divide the inside of the chassis 111 into two spaces, left and right. The blower assembly 12 includes side plates 121 fixed at both ends inside the housing 111. Inside the housing 111, there are three blower pipes 122 arranged front to back. The three blower pipes 122 form a group, and several groups are arranged in an array. The two ends of the blower pipes 122 are rotatably mounted to the side plates 121 at both ends. Several blower heads 123 are fixed on the blower pipes 122 and arranged equidistantly. An active swing arm 124 is fixed to the outer wall of the right end of one of the blower pipes 122. A connecting rod 125 is pivotally connected to the other end of the active swing arm 124. A motor 126 is installed on the outer wall of the housing 111. A rotating arm 127 is fixed to the output end of the motor 126. The other end of the rotating arm 127 is pivotally connected to the end of the connecting rod 125 away from the active swing arm 124.

[0016] In this embodiment, the rotating arm 127 is driven to rotate by the motor 126, and the active swing arm 124 is driven to swing periodically via the connecting rod 125, thereby causing a blower pipe 122 fixed thereto to rotate back and forth around its axis. The swing of the blower pipe 122 blows the dry low-temperature airflow onto the surface of the workpiece in a swinging sweeping manner through the blower head 123 on it, so that the airflow can cover the concave and convex parts of the workpiece, achieving a more uniform and dead-angle-free drying process, effectively preventing local water accumulation, and improving the drying effect and product quality.

[0017] Specifically, the blower assembly 12 also includes a driven swing arm 128 fixed to the outer wall of the left end of the blower pipe 122, and the driven swing arms 128 on the three blower pipes 122 arranged in the front and rear are pivotally connected to the same transverse connecting rod 129.

[0018] In this embodiment, driven swing arms 128 are provided at the left end of the three air pipes 122 arranged in the front and rear, and the three driven swing arms 128 in the same group are pivotally connected together by the transverse connecting rod 129. When the motor 126 drives one of the air pipes 122 to swing through the transmission mechanism, the movement is transmitted through the active swing arm 124 and the connecting rod 125, and further drives the driven swing arms 128 on the other two air pipes 122 in the same group to move in tandem through the transverse connecting rod 129. This ensures that the three air pipes 122 arranged in the front and rear in the same group and all the air blowers 123 on them swing precisely and synchronously, so that the drying airflow can cover the surface of the workpiece in a coordinated sweeping pattern.

[0019] Specifically, the blower assembly 12 is characterized by the fact that it further includes a single longitudinal link 1210 pivotally connected among several transverse links 129.

[0020] In this embodiment, by pivoting the same longitudinal link 1210 between the transverse links 129 of each group of air pipes 122, the swing mechanisms of several groups of air pipes 122 arranged in an array above and below are all linked together as a whole. When the motor 126 drives one group of air pipes 122 to swing, the motion is transmitted to the transverse link 129 of this group through the active swing arm 124 and the connecting rod 125, and further transmitted synchronously to the transverse links 129 of all other groups through the longitudinal link 1210, thereby driving all the air pipes 122 arranged above and below and their blower heads 123 to achieve precise synchronous swing globally.

[0021] Specifically, the blower assembly 12 also includes a rotary joint 1211 installed at the right end of the blower pipe 122. The rotary joints 1211 on the three blower pipes 122 arranged in the front and rear are connected by the same air supply pipe 1212, and the air supply pipes 1212 are connected by the same air supply pipe 1213.

[0022] In this embodiment, a rotary joint 1211 is installed at the right end of the blower pipe 122, and the rotary joints 1211 of the three blower pipes 122 in the same group are connected to each other through the same air supply pipe 1212. At the same time, the air supply pipes 1212 of all groups are finally connected to the same air supply pipe 1213. The dry cold air generated by the refrigeration system 114 is stably input through the air supply pipe 1213 and distributed to each air supply pipe 1212. Then, it is delivered to the continuously reciprocating blower pipe 122 through the rotary joint 1211 and blown out from the blower head 123.

[0023] Specifically, the main component 11 also includes cabinet doors 113 installed on both sides of the front end of the chassis 111, a refrigeration system 114 installed at the lower end of the chassis 111, and the lower end of the air supply duct 1213 connected to the refrigeration system 114, and an air exchange system 115 installed at the upper end of the chassis 111.

[0024] In this embodiment, the refrigeration system 114 installed at the bottom of the chassis 111 continuously cools the passing air to below the dew point temperature through the compression-condensation-expansion-evaporation cycle of its internal refrigerant, causing water vapor in the air to condense and precipitate, thereby continuously supplying low-temperature dry air to the blower assembly 12; at the same time, the ventilation system 115 installed at the top of the chassis 111 continuously discharges the water vapor generated by the evaporation of the workpiece and the humid air in the cavity through forced ventilation, maintaining a stable low absolute humidity environment in the cavity.

[0025] Specifically, the dryer 1 also includes several brackets 13 fixed to the inner wall of the side plate 121 and arranged vertically, with trays 14 placed on the brackets 13.

[0026] In this embodiment, the ferrous rolled products to be processed can be placed in layers on each tray 14, and the air blowing pipe 122 located above each layer of tray 14 drives the air blowing head 123 to accurately and evenly blow the dry low temperature airflow from the refrigeration system 114 onto the surface of the corresponding layer of workpiece by swinging.

[0027] The working principle and usage process of this utility model are as follows: First, the ferrous rolled products to be processed are placed in layers on trays 14 supported by brackets 13 on the inner wall of the side plate 121. After ensuring that the workpieces are stably positioned on each tray 14, the cabinet door 113 is closed to form a sealed working space. Then, the refrigeration system 114 installed at the bottom of the machine box 111 starts to operate. Through the compression-condensation-expansion-evaporation cycle of the refrigerant inside, the processing air is cooled to below the dew point temperature to precipitate moisture and generate a continuous and stable low-temperature dry air. This dry air is delivered to each air supply pipe 1212 through the air supply pipe 1213, and then dynamically distributed to all continuously oscillating blow pipes 122 through the rotary joint 1211. At the same time, the motor 126 drives the rotating arm 127 to rotate, and through the connecting rod 125 and the main The movable swing arm 124 drives an active air duct 122 to swing. This swing is transmitted synchronously to all the air ducts 122 arranged in front and behind and arranged in the upper and lower arrays through a linkage mechanism composed of a driven swing arm 128, a transverse connecting rod 129 and a longitudinal connecting rod 1210, driving all the air blowers 123 to achieve global synchronous swing. The dry low-temperature airflow sprayed from the air blower 123 accurately covers the entire surface of the workpiece on each tray 14 in a coordinated swing sweeping pattern, effectively blowing away moisture and preventing local water accumulation. During this process, the ventilation system 115 installed on the upper part of the chassis 111 continuously forces the discharge of water vapor generated by the evaporation of the workpiece and the humid air in the cavity, working together with the refrigeration system 114 to maintain a stable low humidity environment in the cavity, jointly ensuring that the surface of the workpiece receives efficient, uniform drying treatment without secondary condensation.
