Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and more specifically, to a dryer with an embedded spark detector. Background Technology

[0002] Traditional dryers may generate sparks when drying flammable materials such as textiles and grains due to internal mechanical friction or electrical faults. If these sparks are not detected and dealt with in time, they can easily cause a fire. To improve safety, spark detectors can be embedded inside for warning and alarm purposes. However, in actual use, multiple optical detectors need to be installed to improve detection accuracy, increasing operating costs and making installation cumbersome. Therefore, we propose a dryer with an embedded spark detector. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a dryer with an embedded spark detector to solve the technical problem of high cost of current spark detectors in actual use.

[0004] To solve the above technical problems, the present invention provides the following technical solution: a dryer with an embedded spark detector, comprising a dryer body, a door movably installed on one side of the dryer body, a hot air blower connected to the other side of the dryer body, a placement seat placed inside the dryer body, an exhaust port provided above the placement seat, a fan provided at one end of the exhaust port, and a cyclone separator fixed between the fan and the exhaust port;

[0005] The cyclone separator is equipped with an optical detection structure, which includes multiple guide vanes. The guide vanes face the air inlet and are installed at an angle. Below the guide vanes is a sleeve that rotates synchronously with the guide vanes. Multiple refractive crystals are fixed on the inner wall of the sleeve. A collection cylinder is installed at the bottom of the cyclone separator, and an optical detector is installed at the center of the bottom of the collection cylinder. The optical detector is connected to the main body of the spark detector.

[0006] Preferably, the placement base includes a placement shell, and multiple placement plates are installed inside the placement shell. The placement plates are inclined structures with a central protrusion. The interior of the placement shell is hollow and connected to a hot air inlet. Multiple upwardly inclined heat dissipation holes are provided on the inner wall of the placement shell.

[0007] Preferably, the optical detection structure includes a fixing ring, the bottom of which is fixed to a plurality of guide vanes, and the outer periphery of which is rotatably connected to the inner wall of the cyclone separator.

[0008] Preferably, the top of the sleeve is connected to multiple spiral blades, which are distributed radially along the inner wall of the cyclone separator, and a connecting rod is connected between the top of several spiral blades and the bottom of the corresponding guide vane.

[0009] Preferably, the plurality of the refractive crystals are arranged in a ring array around the cyclone separator, the refractive crystals have a multi-faceted rhomboid structure, and the surface of the refractive crystals is made of a smooth material that can refract light.

[0010] Preferably, the collecting cylinder has a tapered structure with decreasing diameter from top to bottom, and multiple refractive crystals are installed on the inner wall of the collecting cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model can detect sparks inside the dryer using only one optical detector. Compared with the traditional method that requires the installation of multiple optical detectors, it greatly reduces the number of detectors used, lowers procurement and installation costs, simplifies the installation process, and solves the problem of high cost of spark detectors in actual use.

[0013] 2. This utility model also achieves gas-solid separation through a cyclone separator inside the dryer, which guides solid particles that may contain sparks to the collection cylinder. The light generated by the particles is more easily captured by the optical detector after being refracted by the refracting crystal inside the collection cylinder, thus improving the detection specificity. Multiple guide vanes of the optical detection structure rotate under the gas impulse, which guides the gas and enhances the gas-solid separation effect. The refracting crystal on the inner wall of the sleeve rotates synchronously with the sleeve, refracting the spark particles from different angles, further improving the spark detection efficiency and further solving the problem of high cost in actual use of spark detectors.

[0022] like Figures 1 to 5 As shown, this utility model relates to a dryer with an embedded spark detector. The dryer body 1, as the core load-bearing component of the equipment, is made of high-strength, high-temperature resistant high-quality metal material, such as stainless steel. Its robust structure not only provides stable support for the internal components but also has good heat insulation performance, reducing heat loss and improving energy utilization efficiency. A door 2 is movably installed on one side of the dryer body 1 via a hinge or other reliable connecting device. The door 2 is designed to facilitate loading and unloading of materials and is equipped with a sealing strip to ensure the airtightness of the internal environment during the operation of the dryer, preventing heat and harmful gas leakage. A hot air blower 3 is connected to the other side of the dryer body 1. The hot air blower 3 is responsible for delivering heated hot air into the dryer to provide the heat required for the drying process. The power and hot air output temperature of the hot air blower 3 can be adjusted according to the drying requirements of different materials to achieve precise drying.

[0023] Inside the dryer body 1, a highly efficient spark detection system is constructed. An exhaust vent is located above the placement seat 4, with a fan installed at one end. The fan, acting as an airflow drive device, generates strong suction, causing airflow inside the dryer and expelling sparks, dust, and other particulate matter generated during the drying process through the exhaust vent. Between the fan and the exhaust vent, a cyclone separator 5 is fixed. The cyclone separator 5 employs advanced gas-solid separation technology; its unique internal structure allows the airflow containing sparks and dust to rotate at high speed inside the cylinder. Under centrifugal force, solid particles are thrown against the cylinder wall and slide down it, while the gas rises in the central area, achieving gas-solid separation. A collection cylinder 7 is installed at the bottom of the cyclone separator 5. The collection cylinder 7... The design features a tapered structure with decreasing diameter from bottom to top. This tapered structure helps guide the separated solid particles to fall smoothly and be collected at the bottom. Multiple refractive crystals 604 are installed on the inner wall of the collection cylinder 7. The refractive crystals 604 are made of optical materials with high transparency and high refractive index, such as special glass or crystals. They are distributed at specific angles and positions on the inner wall of the collection cylinder 7, which can refract and reflect the light emitted by the spark particles multiple times, focusing the light onto the optical detector 8 installed at the center of the bottom of the collection cylinder 7. The optical detector 8 uses a high-sensitivity optical sensor, which can quickly and accurately detect the light emitted by the spark particles, thereby realizing real-time monitoring of sparks inside the dryer. The optical detector 8 is connected to the spark detector body.

[0024] The dryer body 1 contains a placement seat 4, which consists of a placement shell 401 and multiple placement plates 402. The placement shell 401 is made of high-temperature and corrosion-resistant material and has a hollow structure inside, connected to the hot air inlet. Hot air flows inside the placement shell 401 and is evenly blown onto the material on the placement plates 402 through multiple upward-sloping heat dissipation holes on the inner wall of the placement shell 401, achieving comprehensive drying of the material. The placement plates 402 are installed inside the placement shell 401 and have a centrally protruding inclined structure. This inclined design helps guide the sparks and dust particles generated during the drying process to move upward. At the same time, the placement plates 402 can be set as a mesh frame structure to avoid the material forming isolation between layers, ensuring that the hot air can flow freely between the materials in each layer, improving drying efficiency. The inclined structure of the placement plates 402 and the heat dissipation holes on the placement shell 401 work together to provide an upward driving force for sparks and other particles, enabling them to rise quickly, enter the exhaust port, and then be collected and detected by the cyclone separator 5.

[0025] Working principle: When a spark is generated, it circulates internally and is discharged from the exhaust port. During the discharge process, gas is input through the cyclone separator 5. When the gas rotates and reaches the bottom of the cyclone separator 5, it rises in the central area and is discharged again. The spark particles will gradually fall down along the side wall of the cyclone separator 5 to the collection cylinder 7. Then, through the refraction of the refractive crystal 604 and in conjunction with the optical detector 8, the spark particles can be detected.

[0026] Its advantages lie in the fact that its design can detect sparks inside through a single optical detector 8, which greatly reduces the number of detectors used and lowers the cost of use. Furthermore, the gas-solid separation by the cyclone separator 5 can guide solid particles that may contain sparks to the scattering and focusing cavity. Since sparks usually exist in the form of high-temperature particles, this allows the optical detector 8 to detect these potential ignition sources more concentratedly, improving the detection targeting and potentially increasing detection efficiency. After the gas-solid separation structure accurately delivers solid particles that may contain sparks to the scattering and focusing cavity, the light generated by these particles undergoes multiple reflections and focusing within the cavity, making it easier for the detector to capture.

[0027] To further improve detection efficiency, a photoelectric detection structure 6 is installed inside the cyclone separator 5. The photoelectric detection structure 6 includes multiple guide vanes 601, with one end of each vane facing the air inlet. The guide vanes 601 are installed at an angle. Below each guide vane 601 is a sleeve 603 that rotates synchronously with it. Multiple refractive crystals 604 are fixed to the inner wall of the sleeve 603. The photoelectric detection structure 6 includes a fixing ring 602, the bottom of which is fixed to the multiple guide vanes 601. The outer periphery of the fixed ring 602 is rotatably connected to the inner wall of the cyclone separator 5. The top of the sleeve 603 is connected to multiple spiral blades 605, which are distributed radially along the inner wall of the cyclone separator 5. A connecting rod 606 is connected between the top of several spiral blades 605 and the bottom of the corresponding guide vane 601. Multiple refracting crystals 604 are arranged in a ring array around the cyclone separator 5. The refracting crystals 604 have a multi-faceted rhomboid structure and the surface of the refracting crystals 604 is made of a smooth material that can refract light.

[0028] Working principle: During the gas input process, multiple guide vanes 601 are induced to rotate. The inclined design of the guide vanes 601 can guide the gas and generate lateral rotational force, ensuring the gas-solid separation effect. Then, through the rotational connection of the fixed ring 602 and the connection of the connecting rod 606, the spiral blade 605 and the sleeve 603, the spiral blade 605 can guide the gas and prevent sparks and other particles from colliding with each other, thus enhancing the gas-solid separation effect. In addition, the multiple refractive crystals 604 on the inner wall of the sleeve 603 rotate and can refract spark particles from different angles, greatly improving the efficiency of spark detection.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
