Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment, and in particular to a connection device for preventing slurry leakage. Background Technology

[0002] Slag removal from cooling reactors is a fundamental unit operation in the organosilicon chemical industry. Its purpose is to remove byproducts from the production unit and ensure normal operation. Common slag removal operations from cooling reactors have the following drawbacks: 1. The slag discharge operation of the cooling kettle uses a steel wire hose tied to the discharge port for transportation, which is prone to pipe perforation and leakage; 2. Steel wire hoses have poor fixing effect and are prone to falling off; Third, the slag discharge operation of the cooling kettle has low discharge efficiency. When nitrogen is used for purging, the pipeline is prone to bulging, which is neither safe nor environmentally friendly. Summary of the Invention

[0003] The technical problem to be solved by this utility model is that steel wire hoses are prone to puncture and detachment when discharging slag, and have low discharge efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a connection device for preventing slurry leakage, including a fabric-reinforced rubber hose, carbon steel pipes detachably connected to both ends of the fabric-reinforced rubber hose, and a first flange and a second flange respectively fixed to the movable ends of the two carbon steel pipes.

[0005] Preferably, the carbon steel pipe has a threaded end and is connected to the fabric-reinforced rubber hose through the threaded end.

[0006] Preferably, an annular shoulder is provided on the outer side of one end of the carbon steel pipe that connects to the fabric-reinforced rubber hose. The outer diameter of the annular shoulder is larger than the outer diameter of the fabric-reinforced rubber hose, and the annular shoulder is located at the end of the threaded opening.

[0007] Preferably, the fabric-reinforced rubber tube is provided with an inner rubber layer, a fabric-reinforced layer and an outer rubber layer from the inside to the outside.

[0008] Preferably, the first flange is connected to the cooling kettle flange at the discharge end of the cooling kettle, the second flange is connected to the slurry tank valve flange at the input end of the slurry tank, and the movable end of the carbon steel pipe corresponding to the second flange is coaxially fixedly connected to an insertion pipe, with the second flange located between the carbon steel pipe and the insertion pipe.

[0009] Preferably, double-layer sealing gaskets are provided between the first flange and the cooling vessel flange, and between the second flange and the slurry tank valve flange, with the outer diameter of the sealing gaskets being consistent with the outer diameter of the flange sealing surface.

[0010] Preferably, the entire connecting device is equipped with an electrostatic jumper wire, the length of which is greater than the length of the connecting device, and both ends of the electrostatic jumper wire are fixedly connected to bolts in the first flange and the second flange respectively through terminals.

[0011] This utility model provides a connection device to prevent slurry leakage, which has the following beneficial effects.

[0012] Using a fabric-reinforced rubber hose as the core conveying component, its composite structure, consisting of an inner rubber layer, a fabric layer, and an outer rubber layer, significantly improves impact resistance and wear resistance compared to traditional single-material steel wire hoses. It can effectively resist the abrasion and corrosion of organosilicon slurry. The carbon steel pipes connected at both ends provide rigid support for the fabric-reinforced rubber hose, preventing localized damage caused by uneven stress. The threaded connection at the end of the carbon steel pipe ensures a tight and seamless connection between the fabric-reinforced rubber hose and the carbon steel pipe, structurally eliminating the path for slurry seepage and leakage. This solves the problem of easy perforation of traditional steel wire hoses and improves the service life and operational reliability of the device. Attached Figure Description

Slurry tank valve flange; 9. Cooling kettle; 10. Slurry tank; 14. Static electricity jumper wire. Detailed Implementation

[0016] like Figure 1 and Figure 2 As shown, this utility model provides a connection device to prevent slurry leakage, including a carbon steel pipe fitting 1, a threaded joint 2, a fabric-reinforced rubber hose 3, a first flange 4, a second flange 5, and an electrostatic jumper wire 14.

[0017] Among them, the fabric-reinforced rubber tube 3 consists of an inner rubber layer, a fabric-reinforced layer, and an outer rubber layer from the inside out, and has wear-resistant and corrosion-resistant properties.

[0018] The carbon steel pipe 1 has a threaded end 2 with a pitch matching, and an annular shoulder is integrally formed at the end of the threaded end 2. The outer diameter of the shoulder is larger than the outer diameter of the fabric-reinforced rubber pipe 3.

[0019] The threaded ends 2 of the two carbon steel pipes 1 are pressed into the two ends of the fabric-reinforced rubber hose 3 by a pressing process. The annular shoulder can axially limit the fabric-reinforced rubber hose 3 to prevent slippage under the action of conveying pressure.

[0020] At the end of the carbon steel pipe 1 furthest from the fabric-reinforced rubber hose 3, a first flange 4 is directly welded; at the end of the carbon steel pipe 1 furthest from the fabric-reinforced rubber hose 3, a second flange 5 is welded 25cm away from its end, so that the end of the carbon steel pipe 1 at the rear end forms an insertion tube 7 with a length of 25cm. Finally, a PTFE sleeve is fitted on the outer wall of the insertion tube 7 to prevent material from dripping after the operation is completed.

[0021] Take an electrostatic jumper wire 14 with a length greater than the overall length of the device, and connect its two ends to the fixing bolts on the first flange 4 and the second flange 5 through the terminal blocks to ensure that the wiring is firm and has good conductivity, thus completing the overall assembly of the device.

[0022] First, clean the sealing surface of the cooling vessel flange 6 at the discharge end of the cooling vessel 9. Place a double-layer graphite-reinforced PTFE gasket on the sealing surface, ensuring the outer diameter of the gasket is equal to the outer diameter of the flange sealing surface, and align the gasket completely with the flange sealing surface. Then, attach the first flange 4 to the cooling vessel flange 6, insert bolts, and tighten them sequentially, ensuring no gaps at the flange connection surfaces. Simultaneously, connect one end of the static electricity jumper 14 to the cooling vessel 9 via a wire. Since the cooling vessel 9 is grounded, the connection device is grounded, forming a complete static electricity discharge circuit.

[0023] Clean the sealing surface of the slurry tank valve flange 8 at the input end of the slurry tank 10, and after laying a double layer of sealing gaskets, align and fit the second flange 5 with the slurry tank valve flange 8, and tighten it with bolts. At this time, insert the insertion pipe 7 coaxially into the feed port of the slurry tank 10 to achieve precise slurry diversion.

[0024] After the connection is completed, close the slurry tank valve and introduce 0.8MPa compressed nitrogen into the connection device through the nitrogen purging pipe of the cooling vessel 9 for a pressure holding test. After holding the pressure for five minutes, check the flange connection and the connection between the carbon steel pipe 1 and the fabric-reinforced rubber hose 3 for any leaks. At the same time, use an electrostatic tester to check the conductivity of the electrostatic jumper 14 to ensure that the electrostatic grounding resistance is less than 10Ω, which meets the explosion-proof safety requirements.
