Description

Technical Field

[0001] This utility model relates to the field of reactor cleaning technology, specifically a wastewater discharge device for reactor cleaning. Background Technology

[0002] In the field of adhesive production, reaction vessels are key equipment for realizing core chemical reactions such as raw material polymerization, crosslinking, and modification. Their application spans the entire production process of mainstream adhesives such as hot melt adhesives, pressure-sensitive adhesives, and epoxy adhesives. Adhesive production typically uses reaction vessels, and a feed pipe and a wastewater pipe are installed at the bottom of the reaction vessel. The feed pipe transports materials within the reaction vessel, while the wastewater pipe allows wastewater generated during the cleaning of the reaction vessel's interior after each batch of adhesive production to drain out.

[0003] For example, the publication number is CN222606350U, the publication date is March 14, 2025, and the title is "A Reactor that is Easy to Clean". It is equipped with a feed pipe and a waste pipe at the bottom of the reactor. The feed pipe is used to output the reactants, and the waste pipe is used to output the wastewater.

[0004] In existing technology, a wastewater pipe is typically connected to the bottom of the reactor, and a feed pipe is vertically connected to the wastewater pipe. Since the bottom of the wastewater pipe needs to be connected to a valve via a flange, the connection point between the wastewater pipe and the feed pipe is located in the middle of the wastewater pipe's length. When the valve is open, the reactor is in a cleaning state, and wastewater flows out through the wastewater pipe. When the valve is closed, the reactants in the reactor are transported by the feed pipe. However, because the wastewater pipe and the feed pipe are T-shaped, when the reactants are transported from the reactor to the feed pipe, some material flows into the wastewater pipe due to gravity and accumulates there. During subsequent cleaning, the accumulated material is discharged with the wastewater, resulting in material waste. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater discharge device for cleaning reaction vessels, so as to solve the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater discharge device for cleaning a reaction vessel, comprising:

[0007] Wastewater pipe, which is connected to the bottom of the reactor;

[0008] A valve that connects to a wastewater pipe; the valve has a handle that rotates on it.

[0009] The feed pipe is connected to the wastewater pipe;

[0010] The sealing mechanism includes a fixed rod fixedly connected to a handle, a connecting rod rotatably connected to the fixed rod, a lever rotatably connected to the connecting rod, a rotating rod rotatably connected to a wastewater pipe, the rotating rod being fixedly connected to the lever, and a sealing plate being fixedly connected to the rotating rod.

[0011] Furthermore, the feeding pipe is connected to the wastewater pipe via a connecting pipe.

[0012] Furthermore, the feed pipe and the connecting pipe, as well as the wastewater pipe and the valve, are all connected by flanges.

[0013] Furthermore, it also includes a locking mechanism, which includes a limit frame fixedly connected to the valve, a locking plate slidably connected inside the limit frame, an elastic element provided between the locking plate and the limit frame, and multiple locking grooves opened on the rotating shaft of the handle, with the locking plate and locking grooves interlocking.

[0014] Furthermore, the elastic element is a compression spring.

[0015] Furthermore, the locking plate is L-shaped.

[0016] Compared with the prior art, the wastewater discharge device for cleaning a reaction vessel provided by this utility model, by setting a sealing mechanism, opens the valve when discharging the wastewater. During the valve rotation, the connecting rod drives the lever, rotating rod, and sealing plate to rotate synchronously around the axis of the rotating rod, so that the sealing plate rotates from a horizontal state to a vertical state, thereby canceling the blockage of the wastewater pipe and allowing the wastewater to be discharged. When conveying materials, the horizontal sealing plate can block the wastewater pipe to prevent materials from accumulating in the wastewater pipe and avoid material waste.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-5 This utility model provides a wastewater discharge device for cleaning a reactor, comprising: a wastewater pipe 1 connected to the bottom of the reactor; a valve 2 connected to the wastewater pipe 1; a handle 3 rotatably connected to the valve 2; and a feeding pipe 4 connected to the wastewater pipe 1. Specifically, the feeding pipe 4 is connected to the wastewater pipe 1 via a connecting pipe 5. Preferably, and more specifically, the connecting pipe 5 is inclined, that is, the end of the connecting pipe 5 near the feeding pipe 4 is higher than the end near the wastewater pipe 1. The advantage of this arrangement is that it prevents wastewater from flowing into the feeding pipe 4 during wastewater discharge. Even if wastewater splashes into the connecting pipe 5, because the connecting pipe 5 is inclined, the wastewater will flow down along the inner wall of the connecting pipe 5 into the wastewater pipe 1 for discharge. Specifically, the feeding pipe 4 and the connecting pipe 5, as well as the wastewater pipe 1 and the valve 2, are connected by flanges 6.

[0026] A sealing mechanism 7 is used to seal the position on the wastewater pipe 1 that is connected to the connecting pipe 5. Specifically, it includes a fixed rod 71 fixedly connected to the handle 3, a connecting rod 72 rotatably connected to the fixed rod 71, a lever 73 rotatably connected to the connecting rod 72, and a rotating rod 74 rotatably connected to the wastewater pipe 1. Specifically, the wastewater pipe 1 has a rotating hole for the rotating rod 74 to rotate through. Specifically, a sealing ring is provided between the rotating rod 74 and the rotating hole. The rotating rod 74 extends into the interior of the wastewater pipe 1. The rotating rod 74 is fixedly connected to the lever 73, and a sealing plate 75 is fixedly connected to the rotating rod 74. Specifically, the sealing plate 75 is circular. Preferably, both ends of the sealing plate 75 are rounded. More preferably, an elastic sealing gasket is fixedly connected to the circumference of the sealing plate 75. The elastic sealing gasket abuts against the inner wall of the wastewater pipe 1, and the elastic sealing gasket can seal the gap between the sealing plate 75 and the inner wall of the wastewater pipe 1.

[0027] Preferably, it also includes a locking mechanism 8 for locking the handle 3; it includes a limiting frame 81 fixedly connected to the valve 2, and a locking plate 82 slidably connected within the limiting frame 81; specifically, the locking plate 82 is L-shaped; an elastic element 83 is provided between the locking plate 82 and the limiting frame 81; specifically, the elastic element 83 is a compression spring; the process of the elastic element 83 undergoing elastic deformation and contraction drives the locking plate 82 to be pulled out from the locking groove 31; a plurality of locking grooves 31 are provided on the rotating shaft of the handle 3, and the locking plate 82 is inserted into the locking grooves 31.

[0028] Working principle: During use, valve 2 is in the closed state during material conveying, that is, handle 3 and sealing plate 75 are both set horizontally, so that sealing plate 75 blocks wastewater pipe 1. Material flows from wastewater pipe 1 into feed pipe 4 for conveying, preventing material from passing over sealing plate 75, thereby avoiding material accumulation in wastewater pipe 1 and thus avoiding material waste in the subsequent wastewater discharge process.

[0029] When wastewater is discharged, the locking plate 82 is moved to compress the elastic element 83, causing the elastic element 83 to deform and contract, thus pulling the end of the elastic element 83 out of the locking groove 31 to release the lock on the handle 3. Then, the handle 3 of the valve 2 is rotated to change from a horizontal to a vertical position. During the rotation of the handle 3, the connecting rod 72 drives the lever 73, the rotating rod 74, and the sealing plate 75 to rotate synchronously around the axis of the rotating rod 74, and the sealing plate 75 rotates to a vertical position, cleaning the wastewater generated by the reactor, which enters the wastewater pipe 1 from the reactor and is discharged through the valve 2.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
