A splash-proof and corrosion-resistant drying oven

Abstract

This utility model provides a splash-proof and corrosion-resistant drying oven, including a drying chamber with a component chamber inside. A cover plate is fixedly installed at the top of the drying chamber. A material corrosion-resistant tank is located inside the component chamber, and a connecting pipe is installed at the top of the material corrosion-resistant tank, extending upwards and penetrating the cover plate. This design utilizes a tapered input cavity with a gradually decreasing cross-sectional area to increase the material flow rate and create a negative pressure zone, suppressing pressure buildup. The symmetrically arranged exhaust pipes on both sides can directionally discharge the overpressure steam generated by material vaporization, preventing excessive pressure from causing material to splash from the input port. Furthermore, the material corrosion-resistant tank is made of 316L stainless steel or titanium alloy and undergoes electrolytic polishing to eliminate microporous corrosion sources on the inner wall, significantly improving its resistance to corrosive materials and extending the equipment's service life.

Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion and drying technology, specifically to an anti-splash and anti-corrosion drying box. Background Technology

[0002] As a core piece of equipment for dehydrating and drying materials in industrial production, the performance of the drying oven directly affects product quality and production safety.

[0003] Existing drying ovens present a technical contradiction between corrosion protection and splash prevention. Most equipment focuses only on a single function of corrosion protection or splash prevention, lacking integrated design. Surface coating corrosion protection technology is difficult to cope with high temperature and high humidity environments, while structural improvement solutions may reduce drying efficiency. Furthermore, when boiling materials are fed into the drying oven, they are prone to splashing onto the heating elements, causing equipment failure or contamination. Utility Model Content

[0024] This utility model embodiment provides a splash-proof and corrosion-resistant drying box, such as... Figure 1-4 As shown, the device includes a drying chamber 101, a component chamber 102 inside the drying chamber 101, a cover plate 113 fixedly installed at the top of the drying chamber 101, a material corrosion-resistant tank 114 inside the component chamber 102, a connecting pipe 109 installed and connected to the top of the material corrosion-resistant tank 114, the connecting pipe 109 extending upward and penetrating the cover plate 113, a splash-proof pipe 110 installed and connected to the top of the connecting pipe 109, a conical input cavity 116 inside the splash-proof pipe 110, a material pipe 112 with an outward opening at one end of the conical input cavity 116, two outward opening exhaust pipes 111 connected to the top of the splash-proof pipe 110, the exhaust pipes 111 being inclined, one end of the exhaust pipes 111 on both sides being connected to the conical input cavity 116, and the exhaust pipes 111 on both sides being symmetrically positioned.

[0025] It should be further explained that the material pipeline 112 inputs the dehydrated material into the conical input chamber 116 and inputs it downwards. During the input process, excess air pressure is output through the exhaust pipeline 111, which can prevent the material from splashing due to excessive pressure.

[0026] It is worth further explaining that the material corrosion-resistant tank 114 is made of 316L stainless steel or titanium alloy, which provides corrosion protection.

[0027] Furthermore, the bottom of the material corrosion-resistant tank 114 is connected to a material drop pipe 115.

[0028] Furthermore, a horizontal material dryer 104 is provided in the component chamber 102, and an arc-shaped pipe 118 is provided between the middle position of the material dryer 104 and the material falling pipe 115.

[0029] Furthermore, the material dryer 104 is connected to two material output pipes 103 with outward openings at both ends. The material output pipes 103 on both sides are symmetrically positioned, and one end of the material output pipes 103 on both sides penetrates the side wall of the drying chamber 101.

[0030] It should be further explained that the material dryer 104 serves the purpose of drying and outputting. The material dryer 104 is heated by circulating heat transfer oil, and a one-way valve micro-hole is provided on the top of the material dryer 104 for exhaust.

[0031] Furthermore, the drying chamber 101 has an outward-facing opening 119 on one side, which is connected to the component chamber 102.

[0032] Furthermore, the drying chamber 101 is fixedly provided with two rotating bases 108 on one side of the opening 119. The rotating bases 108 on both sides are symmetrically positioned vertically, and a vertical rotating shaft 120 is rotatably connected between the rotating bases 108 on both sides.

[0033] Furthermore, a rotating door 107 is fixedly provided on one side of the outer end face of the vertical rotating shaft 120, and a locking rotating shaft 117 is rotatably connected to one side of the rotating door 107. One end of the locking rotating shaft 117 extends to one side of the rotating door 107 and is fixedly connected to a disc-shaped sealing rotating disk 106.

[0034] Furthermore, a blocking plate 105 is installed and connected to the other end face of the locking shaft 117.

[0035] It should be further explained that when the sealing turntable 106 is rotated, it can drive the locking shaft 117 to rotate, which in turn drives the sealing plate 105 to rotate. At this time, the sealing plate 105 can engage with the inner wall of the component chamber 102 and located on the side of the opening 119, thus achieving a sealing effect.

[0036] The usage method of this solution is as follows:

[0037] S1. The boiling material is injected into the material pipeline 112 through an external pumping system;

[0038] The material enters the conical input cavity 116 along the pipeline. As the cross-sectional area of ​​the cavity gradually shrinks downward, the material flow velocity increases, forming a negative pressure zone.

[0039] Simultaneously open the exhaust pipe 111. The exhaust pipes, which are symmetrically arranged on both sides, direct the overpressure steam generated by the material gasification to avoid pressure accumulation that could cause the material to splash from the inlet.

[0040] Under material input conditions of 80℃, the conical cavity and dual exhaust structure further reduce splashing.

[0041] S2. The material enters the corrosion-resistant material tank 114 through the connecting pipe 109;

[0042] At this time, the inner wall of the anti-corrosion tank is electrolytically polished to eliminate microporous corrosion sources and make it resistant to corrosive environments.

[0043] S3. The material enters the arc-shaped pipe 118 through the material drop pipe 115 at the bottom of the tank and is introduced into the material dryer 104 in a laminar flow state.

[0044] The material dryer 104 uses heat transfer oil circulation heating. Moisture is discharged from the micropores at the top of the material dryer 104. After drying, the material is discharged through the symmetrical material output pipes 103.

[0045] S4. When performing sealing maintenance and component maintenance, the rotating sealing turntable 106 drives the locking shaft 117 to rotate, which causes the sealing plate 105 to disengage from the inner wall slot of the component chamber 102. Then, the rotating door 107 is pulled outward to open the opening mouth 119, and then the staff can perform maintenance work on each component inside 102.

[0046] An explosion-proof membrane is installed at the joint between the cover plate 113 and the drying chamber 101. When the exhaust pipe 111 is blocked, it will rupture first to release pressure.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
