Description

Technical Field

[0001] This utility model relates to the field of ovens, and more particularly to dust removal mechanisms, specifically to a dust removal mechanism for a dust-free oven. Background Technology

[0002] Cleanroom ovens, as highly specialized equipment, play an indispensable role in many industries. Their main applications include, but are not limited to, the electronics, glass, hardware, and food industries. Cleanroom ovens are used for baking and curing products, or for baking and dehumidifying hardware parts to enhance their corrosion resistance and durability. They are also commonly used for post-dispensing curing of screens in automotive and other applications. Therefore, cleanroom ovens are indispensable in current production processes.

[0003] The basic structure of existing cleanroom ovens typically includes several main parts such as the outer shell, frame, heating system, cleanroom tunnel, temperature control system, air circulation system, and safety system. The cleanroom tunnel, as the main working area, is designed as a closed passage to ensure that the materials are not contaminated by the outside environment during the baking process. The tunnel is equipped with a conveyor system, such as a conveyor belt or chain, to transport the materials from one end to the other, through the heating zone, thereby completing the baking and curing of the products.

[0004] However, existing dust removal mechanisms in cleanroom ovens still have some shortcomings. First, the dust removal efficiency of some cleanroom ovens is not high, making it difficult to fully meet the needs of high-precision production. The existing dust removal structures are relatively simple, which leads to dust and particulate matter being carried into the oven by the circulating gas used for heating, making it difficult to effectively capture and filter them. In addition, some existing dust removal mechanisms in cleanroom ovens have insufficient airtightness in their design and installation, causing dust-laden gas to enter the oven without being removed by dust removal, thus affecting the cleanliness of the product and the baking effect, which is not conducive to the use of the oven. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a dust removal mechanism for a dust-free oven, so as to solve the technical problem in the background art that the existing dust-free ovens have poor dust removal effect and are not easy to effectively filter, resulting in dust-containing gas entering the dust removal mechanism and thus affecting the baking effect.

[0006] The objective of this utility model is achieved through the following means:

[0007] A dust removal mechanism for a dust-free oven includes a baking cabinet and a filter box mounted on the baking cabinet. The baking cabinet has a conveyor belt for transporting materials. The baking cabinet has an inlet and an outlet at each end. The conveyor belt extends from the inlet at one end of the baking cabinet to the outlet at the other end. The filter box contains a dust removal chamber and a heating chamber. The dust removal chamber has an air inlet cavity formed by a partition. One end of the filter box has a ventilation screen communicating with the air inlet cavity. A fan is installed in the air inlet cavity. An air inlet is provided on the partition, allowing the fan's outlet to communicate with the air inlet on the partition, thus connecting the air inlet cavity and the dust removal chamber to form a dust removal and filtration channel. A dust removal filter element is connected to the dust removal chamber via a mounting bracket. A filter screen is connected to one end of the dust removal filter element near the air inlet cavity, and an air collecting hood is connected to the other end of the dust removal filter element. An air outlet duct is connected to the air collecting hood, and the end of the air outlet duct away from the air collecting hood extends towards the heating chamber and is connected to the heating chamber.

[0008] Furthermore, as described above, the ventilation screen is detachably installed on one side of the filter box, and the surface of the ventilation screen has several ventilation holes that communicate with the air inlet cavity.

[0009] Specifically, the ventilation holes allow dust-laden gas from outside to enter the air inlet chamber, where it is driven by a fan and passes through a dust removal chamber for dust removal, thus completing the filtration of the dust-laden gas. The ventilation mesh can also pre-filter the dust-laden gas, reducing the entry of large dust particles.

[0010] Furthermore, as described above, the mounting bracket is installed inside the dust removal chamber, and the mounting bracket has a mounting slot for holding the dust removal filter element. The dust removal filter element has a central hole inside, and a sealing plate for installing the dust removal filter element is provided inside the dust removal chamber. The sealing plate has an exhaust hole that communicates with the central hole of the dust removal filter element.

[0011] Specifically, the dust-laden gas can be effectively filtered by the dust-removing filter element. After being filtered through the outer surface of the filter element, the clean gas passes through the surface of the filter element and is discharged from the exhaust port, further enhancing the filtration effect of the dust-laden gas.

[0012] Furthermore, as described above, the air collecting hood is installed on the side of the sealing plate and is connected to the exhaust port, so that the filtered gas passes through the air collecting hood and is introduced into the heating chamber through the air outlet pipe for heating.

[0013] Specifically, the air collection hood reduces gas backflow in the heating chamber, allowing the gas to be filtered through the dust removal chamber and then discharged through the air outlet duct under the drive of the fan, thus enhancing the filtration effect of the gas.

[0014] Furthermore, as described above, the filter screen is installed in the dust removal chamber, and the surface of the filter screen has several through-holes.

[0015] The filter screen can perform secondary filtration of the dust-laden gas introduced into the air inlet cavity, and then filter it through the dust removal filter element, thereby enhancing the filtration effect of the dust-laden gas.

[0016] Furthermore, as described above, the baking cabinet is equipped with two static eliminators, which are respectively installed at the inlet and outlet of the baking cabinet.

[0017] The static eliminator can neutralize the static charge on the surface of an object by releasing positive and negative charges, thereby eliminating static electricity and reducing or eliminating adsorption caused by static electricity. This further reduces dust adsorption on the surface of the object, thus enhancing the baking effect of the dust-free oven.

[0018] Furthermore, as described above, the bottom wall of the heating chamber is provided with an air vent that communicates with the baking cabinet, and an electric heating tube for heating gas is connected inside the heating chamber.

[0019] The beneficial effects of this utility model are as follows: By designing a filter box containing a dust removal chamber and a heating chamber, and equipping the dust removal chamber with a dust removal filter element and filter screen, dust particles in the dust-laden gas are effectively captured and filtered. A fan ensures that dust-laden air is efficiently drawn into the air inlet cavity, and the filtration effect of the dust removal filter element improves dust removal efficiency. The filtered clean air, under the heating chamber, reduces the amount of dust carried by the gas into the baking cabinet, thus ensuring the cleanliness of the baking environment and improving the baking quality of the product. Furthermore, the connection between the air inlet cavity and the dust removal chamber via a partition and air inlet forms a dust removal and filtration channel, accelerating the direction and speed of airflow through the connection between the fan and the air inlet, making the dust removal process more efficient and orderly. Simultaneously, the cooperation between the air collection hood and the air outlet duct guides the filtered clean air to the heating chamber. Through efficient dust removal and filtration, the entry of dust and other harmful substances into the heating chamber is reduced, thereby reducing the adhesion of dust carried by the heat source to the product during baking, thus improving the dust removal and filtration effect of the gas.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] In this embodiment, refer to Figures 1-4 The dust removal mechanism of a dust-free oven, specifically implemented therein, includes a baking cabinet 1 and a filter box 2 mounted on the baking cabinet 1. The baking cabinet 1 has a conveyor belt for transport inside. The baking cabinet 1 has an inlet 3 and an outlet 4 at both ends. The conveyor belt extends from the inlet 3 at one end of the baking cabinet 1 to the outlet 4 at the other end. The filter box 2 contains a dust removal chamber 5 and a heating chamber 6. The dust removal chamber 5 has an air inlet cavity 8 formed by partitions 7. One end of the filter box 2 is equipped with a ventilation mesh 9 communicating with the air inlet cavity 8. A fan 10 is provided, and an air inlet 11 is provided on the partition 7 so that the air outlet of the fan 10 is connected to the air inlet 11 on the partition 7, thereby connecting the air inlet chamber 8 and the dust removal chamber 5 to form a dust removal and filtration channel. A dust removal filter element 13 is connected to the dust removal chamber 5 through a mounting bracket 12. A filter screen 14 is connected to one end of the dust removal filter element 13 near the air inlet chamber 8, and an air collecting hood 15 is connected to the other end of the dust removal filter element 13. An air outlet duct 16 is connected to the air collecting hood 15. The end of the air outlet duct 16 away from the air collecting hood 15 extends towards the heating chamber 6 and is connected to the heating chamber 6.

[0027] In this embodiment, the ventilation mesh 9 is detachably installed on one side of the filter box 2, and the surface of the ventilation mesh 9 is provided with ventilation holes 17 that communicate with the air inlet chamber 8. Specifically, the dust-laden gas from outside enters the air inlet chamber 8 through the ventilation holes 17 and is driven by the fan 10 to pass through the dust removal chamber 5 for dust removal treatment, thereby completing the filtration of the dust-laden gas. The ventilation mesh 9 can pre-filter the dust-laden gas, reducing the entry of large dust particles.

[0028] In this embodiment, the mounting bracket 12 is installed inside the dust removal chamber 5, and the mounting bracket 12 has a mounting slot for holding the dust removal filter element 13. The dust removal filter element 13 has a central hole 18 inside. A sealing plate 19 for installing the dust removal filter element 13 is provided inside the dust removal chamber 5. The sealing plate 19 has an exhaust hole 20 that communicates with the central hole 18 of the dust removal filter element 13. Specifically, the dust removal filter element 13 can effectively filter dust-laden gas. After being filtered through the outer surface of the dust removal filter element 13, the filtered clean gas passes through the surface of the dust removal filter element 13 and is discharged from the exhaust hole 20, further enhancing the filtration effect on the dust-laden gas.

[0029] In this embodiment, the air collecting hood 15 is installed on the side of the sealing plate 19 and is connected to the exhaust port 20, so that the filtered gas is introduced into the heating chamber 6 for heating through the air outlet duct 16 after passing through the air collecting hood 15. Specifically, the air collecting hood 15 can reduce the backflow of gas in the heating chamber 6, so that under the drive of the fan 10, the gas is filtered through the dust removal chamber 5 and then discharged from the air outlet duct 16, thereby enhancing the filtration effect of the gas.

[0030] In this embodiment, the filter screen 14 is installed inside the dust removal chamber 5, and the surface of the filter screen 14 is provided with through filter holes 21. The filter screen 14 can perform secondary filtration on the dust-laden gas introduced into the air inlet chamber 8, and after being filtered by the dust removal filter element 13, the filtration effect on the dust-laden gas is enhanced.

[0031] In this embodiment, two static eliminators 22 are installed inside the baking cabinet 1, one at the inlet 3 and the other at the outlet 4. The static eliminators 22 neutralize the static charge on the surface of objects by releasing positive and negative charges, thereby eliminating static electricity and reducing or eliminating adsorption caused by static electricity. This further reduces dust adsorption on the surface of objects, enhancing the baking effect of the dust-free oven.

[0032] In this embodiment, the bottom wall of the heating chamber 6 is provided with an air vent 23 that communicates with the baking cabinet 1, and an electric heating tube 24 for heating gas is connected inside the heating chamber 6.

[0033] Specifically, the fan 10 is a blower 10, and the dust removal filter element 13 is composed of filter cartridges, and there are three dust removal filter elements 13.

[0034] The specific operating principle in this embodiment is as follows: The inlet 3 and outlet 4 of the baking cabinet 1 are connected to the external mechanism. The fan 10 is installed in the air inlet chamber 8, and the outlet end of the fan 10 is connected to the air inlet 11 of the partition 7. The controller of the baking cabinet 1 controls the fan 10 to drive it, so that the dust-laden gas outside the filter box 2 is introduced into the dust removal chamber 5 through the air inlet end of the fan 10 and the air outlet end. The ventilation net 9 can pre-filter the dust-laden gas, and when it enters the dust removal chamber 5, it is filtered again by the filter net 14, ensuring that the dust-laden air can be efficiently introduced into the dust removal chamber 5. Through the filtration effect of the dust removal filter element 13, the dust removal efficiency is improved, so that the dust-laden gas is adsorbed and filtered by the outer surface of the dust removal filter element 13, so that the dust carried by the gas is adsorbed on the dust removal filter. On the outer surface of the core 13, the filtered clean gas passes through the dust removal filter element 13 and is discharged from the exhaust port 20, allowing the clean gas to enter the air collection hood 15 and be introduced into the heating chamber 6 through the air outlet duct 16. The gas is then heated by the electric heating tube 24 in the heating chamber 6, forming a baking heat source, which is then introduced into the baking cabinet 1. This reduces the amount of dust carried by the gas into the interior of the baking cabinet 1, thereby ensuring the cleanliness of the baking environment and improving the baking quality of the product. The air inlet chamber 8 and the dust removal chamber 5 are connected by the partition 7 and the air inlet 11 to form a dust removal and filtration channel. This connection between the fan 10 and the air inlet 11 accelerates the directionality and speed of airflow, making the dust removal process more efficient and orderly. Thus, through efficient dust removal and filtration, the dust removal and filtration effect on the gas is improved.
