Description

Cooling water tank convenient for uniform heat exchange

Technical Field

The utility model relates to a wet spinning equipment production field especially relates to a cooling trough convenient to even heat exchange.

Background

Wet spinning is one of the main spinning methods for chemical fibers, and is called wet spinning for short. The wet spinning comprises the following steps: (1) preparing a spinning solution; (2) extruding the stock solution from the spinneret orifices to form fine flows; (3) the stock solution trickles are solidified into nascent fiber; (4) the nascent fiber is packaged or directly post-treated. In the step of coagulating the dope into a nascent fiber, the nascent fiber is usually cooled in a water tank, and then divided into filaments and guided for post-treatment.

As shown in fig. 1 and 2, which are schematic top view and cross-sectional views of a conventional water tank, the water tank is composed of a water bath and an overflow trough, the water bath is used for cooling spinning threads and is mainly connected with a water inlet pipe and a sewage discharge pipe, the overflow trough is used for receiving water overflowing from the water bath, and the bottom of the overflow trough is connected with a water outlet pipe for recycling water. However, the water tank has the following defects: in use, the water tank in fig. 1 and 2 can find that the temperature of water flowing out from the water inlet pipe is low, and the temperature of water near the overflow groove is high, because newly entering water needs to flow to the water outlet end through the water inlet end, and the water in the period can exchange heat with spinning to cause temperature rise, so that the temperature of water at two ends of the water bath tank is inconsistent, the heat exchange effect near the overflow groove end is reduced, and the subsequent production is affected.

Based on this, the present disclosure is thus directed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cooling trough convenient to even heat exchange to improve the heat exchange efficiency who is close to the overflow groove end, the heat exchange effect of each position in the even water bath.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

the cooling water tank convenient for uniform heat exchange comprises a water tank body, wherein the interior of the water tank body is divided into a water tank and an overflow tank, a sewage discharge outlet is formed in the bottom of the water tank, a water outlet is formed in the bottom of the overflow tank, an inner water tank formed by a mesh plate in a surrounding mode is arranged in the water tank, and an outer water tank is formed in a space between the mesh plate and the side wall of the water tank.

Furthermore, four corners and/or central position of the bottom of the water tank body are provided with lifting mechanisms.

Further, the lifting mechanism is a screw mechanism or a hydraulic cylinder.

Further, the mesh plate is a stainless steel plate.

The utility model has the advantages that: through setting up the mesh board, can make the water that newly gets into the basin flow around the water bath, get into interior water bath through the mesh board simultaneously, improved the heat exchange efficiency who is close to overflow tank end, homogenized the heat exchange effect of each position in the water bath.

description of the reference symbols

The device comprises a water bath 1, an overflow trough 2, a sewage discharge outlet 3, a water inlet pipe 4, a water outlet 5, a mesh plate 6, a lifting mechanism 7, an inner water bath 1a and an outer water bath 1 b.

Detailed Description

The present invention will be described in further detail with reference to examples.

The embodiment provides a cooling water tank convenient for uniform heat exchange, which comprises a water tank body, wherein the water tank body is internally divided into a water bath 1 and an overflow trough 2 (the flow direction of water is indicated by arrows in the figures), a sewage discharge outlet 3 is arranged at the bottom of the water bath 1, a water outlet 5 is arranged at the bottom of the overflow trough 2, an inner water bath 1a formed by surrounding a mesh plate 6 is arranged in the water bath 1, and an outer water bath 1b is formed by a space between the mesh plate 6 and the side wall of the water bath 1. The sewage draining outlet 3 is used for cleaning the water tank; the water outlet 5 is used when the water tank normally operates to realize the recycling of water.

Taking fig. 3 as an example, when the device is used, newly injected water firstly enters the outer water bath 1b through the water inlet pipe 4, only part of the new water can enter the inner water bath 1a through the holes of the mesh plate 6 due to the shielding of the mesh plate 6 close to the water inlet pipe 4, the rest of the new water flows along the outer water bath 1b, and the new water enters the inner water bath 1a through the holes on the mesh plate 6 at the front side or the rear side or the side close to the overflow end in the flowing process. Through the design of the mesh plate 6, new water can flow into the inner water bath 1a from the periphery, and spinning can be arranged in the inner water bath 1a when the water bath is cooled, so that the heat exchange effect of all positions in the inner water bath 1a is uniform.

Preferably, the mesh plate 6 of the present embodiment is a stainless steel plate, and has characteristics of corrosion resistance and low cost.

In actual use, the water tank may need to be lifted and adjusted, and because the water tank has a high weight in a full load state, a multi-point supporting synchronous lifting mode needs to be selected to keep the lifting stability of the water tank, as shown in fig. 5 and 6, in this embodiment, lifting mechanisms 7 are arranged at four corners and a central position of the bottom of the water tank body, and preferably, the lifting mechanisms 7 adopt hydraulic cylinders.

The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
