Abstract
Description
Technical Field
[0001] The present application relates to the field of textile technology, and in particular to a hot water recovery device for wet-squeezing of a pulp vat. Background Art
[0002] In the sizing process, the wet slicing process plays an important role in taming the yarn hairiness, maintaining the integrity of the size film, and reducing the resistance during dry slicing. The wet slicing rod is fixed between the size tank and the drying room. Cold water enters the inner cavity of the wet slicing rod, making the surface temperature of the wet slicing rod significantly lower than the ambient temperature. After the yarn is sized in the size tank, it is sliced in a wet state when it leaves the size tank. When passing through the wet slicing rod, due to the temperature difference, condensation forms on the surface of the wet slicing rod to provide lubrication during slicing, smooth sizing, and avoid the drying, accumulation, and adhesion of the size, which is beneficial to the integrity of the size film and the flattening of the hairiness.
[0003] The water connected to the inner cavity of the wet-twisting rod is generally supplied by a pumping station. The condensation temperature of the wet-twisting dew is no more than 13°C. In summer, the ambient temperature is high, the water temperature supplied by the pumping station is relatively high, and the water pressure is low. When the water flow is insufficient, there is almost no condensation on the surface of the wet-twisting rod, and the effect of the wet-twisting is not significant. Therefore, in order to improve the wet-twisting effect, it is usually necessary to increase the wet-twisting operation cycle, which consumes a lot of water. The water flowing through the inner cavity of the wet-twisting rod is directly discharged into the sewer pipe, resulting in a waste of about 200 tons of water resources every day.

[0009] By adopting the above technical scheme, the impeller rotates under the flow of water in the wet wringing rod, thereby driving the rotating shaft to rotate around the axis of the wet wringing rod, thereby driving the cleaning brush to rotate, and then cleaning the inner wall of the wet wringing rod, reducing the probability of scale adhesion due to heat in the wet wringing rod, thereby improving the wet wringing effect of the wet wringing rod, and having a simple structure and easy use.

DETAILED DESCRIPTION
[0027] The following is combined with Figure 1-3 This application is described in further detail.
[0028] The present application discloses a hot water recovery device for pulp tank wet-squeezing. Figure 1 The hot water recovery device of the pulp tank wet-squeezing includes a hollow wet-squeezing rod 2 fixedly installed above the pulp tank 1, and also includes a water storage tank 3, a water pump 4 and a refrigerator 5 arranged on one side of the pulp tank 1. Exemplarily, two wet-squeezing rods 2 are arranged at intervals above and below, and the two wet-squeezing rods 2 are arranged in parallel in the horizontal direction. The ends of the two wet-squeezing rods 2 on the same side are connected by a hose, and the end of the lower wet-squeezing rod 2 away from the hose is connected to the water outlet of the water pump 4 through a water inlet pipe 21. The refrigerator 5 is arranged on the water inlet pipe 21 to cool the water in the water inlet pipe 21.
[0029] The water inlet of the water pump 4 is connected to an electromagnetic three-way valve. For example, the water outlet of the electromagnetic three-way valve is connected to the water inlet of the water pump 4. The first water inlet 61 of the electromagnetic three-way valve is connected to an external water source through a first pipe 62, and the second water inlet 63 of the electromagnetic three-way valve is connected to the water reservoir 3 through a second pipe 64. The end of the upper wet separation wringer 2 away from the hose is also connected to the water reservoir 3 through a water outlet pipe 22.
[0030] When in use, the first water inlet 61 is controlled by the three-way solenoid valve 6 to be connected to the external water source through the first pipe 62. At this time, the second water inlet 63 is in a closed state. The pump 4 is started to pump the external water source through the water inlet pipe 21 and then through the wet-splitting rod 2 into the water reservoir 3. When the water in the water reservoir 3 is full of water, the second water inlet 63 is controlled by the three-way solenoid valve 6 to be connected to the water reservoir 3 through the second pipe 64. At this time, the first water inlet 61 is in a closed state. The pump 4 is started to directly pass the water in the water reservoir 3 through the water inlet pipe 21 into the wet-splitting rod 2. At the same time, the refrigerator 5 works to cool the water in the water inlet pipe 21, thereby improving the wet-splitting effect. The water flowing out of the wet-splitting rod 2 flows into the water reservoir 3 to form a cycle, thereby achieving the effect of saving water resources. The overall structure is relatively simple and easy to use. When the water source in the water reservoir 3 is reduced, the three-way solenoid valve 6 can be adjusted to control the first water inlet 61 to be connected to the external water source through the first pipe 62, so as to replenish the water in the water reservoir 3, ensure that there is sufficient water in the water reservoir 3, and ensure the effect of wet separation.
[0031] Further, see Figure 2 In order to detect the amount of water in the water reservoir 3, a water level monitoring sensor 31 is provided in the water reservoir 3, and the water level monitoring sensor 31 is electrically connected to the three-way solenoid valve 6. When the water level monitoring sensor 31 detects that the amount of water in the water reservoir 3 is insufficient, an electrical signal is sent to the three-way solenoid valve 6, and the three-way solenoid valve 6 controls the first water inlet 61 to be connected to the external water source through the first pipe 62, so as to replenish the water in the water reservoir 3 in time, with a high degree of automation and convenient use.
[0032] In addition, refer to Figure 3 Since the outer surface of the wet-twisting rod 2 is heated, scale will be generated on the inner wall of the wet-twisting rod 2. The scale attached to the inner wall will affect the wet-twisting effect of the wet-twisting rod 2. Therefore, a self-cleaning mechanism is provided in the wet-twisting rod 2, and the self-cleaning mechanism can automatically clean the scale attached to the inner wall of the wet-twisting rod 2. The self-cleaning mechanism includes a rotating shaft 23, an impeller 24 and a cleaning brush 25. The rotating shaft 23 is rotatably connected to the inner wall of the wet-twisting rod 2 through a rotating bearing 26, and the rotating axis of the rotating shaft 23 coincides with the axis of the wet-twisting rod 2. The cleaning brush 25 is evenly distributed on the outer peripheral wall of the rotating shaft 23, and the cleaning brush 25 contacts the inner wall of the wet-twisting rod 2. The impeller 24 is coaxially connected to one end of the rotating shaft 23. After the water pump 4 pumps water into the wet-twisting rod 2, the impeller 24 rotates under the drive of the water flow, driving the rotating shaft 23 to rotate, thereby driving the cleaning brush 25 to clean the scale on the inner wall of the wet-twisting rod 2. The scale enters the water reservoir 3 with the water flow and is precipitated, thereby improving the wet-twisting effect of the wet-twisting rod 2.
[0033] Further, see Figure 2In order to reduce the scale and other impurities in the water reservoir 3 from entering the wet-splitting rod 2 again and affecting the wet-splitting effect, a partition 32 is vertically arranged in the water reservoir 3, and two partitions 32 are arranged at intervals in the horizontal direction. The two partitions 32 divide the chamber of the water reservoir 3 into three sedimentation tanks 33. The outlet pipe 22 is connected to the sedimentation tank 33 at one end of the water reservoir 3, and the second pipe 64 is connected to the sedimentation tank 33 at the other end of the water reservoir 3. The water flowing into the water reservoir 3 through the outlet pipe 22, after three-stage sedimentation in the three sedimentation tanks 33, is pumped into the wet-splitting rod 2 again through the second pipe 64 and basically does not contain impurities.
[0034] Furthermore, an addition port 34 for adding flocculants is provided on the top of the water reservoir 3. Adding flocculants into the water reservoir 3 through the addition port 34 can further enhance the precipitation of impurities in the water, further reduce the probability of impurities in the water entering the wet-squeezing rod 2, and improve the wet-squeezing effect.
[0035] In order to facilitate the discharge of impurities precipitated in the water reservoir 3, the bottom wall of the water reservoir 3 is set to be funnel-shaped, and a silt removal pipe 7 is connected to the bottom of the water reservoir 3. The end of the silt removal pipe 7 away from the water reservoir 3 is connected to the sewer pipe, and a silt removal pump 71 is connected to the silt removal pipe 7 through a flange. By regularly starting the silt removal pump 71, the impurities precipitated in the water reservoir 3 can be discharged, thereby reducing the load and operating costs of the sewage station.
[0036] In addition, in order to reduce the water pollution and bacterial breeding in the water reservoir 3, a plurality of ultraviolet lamps 321 are provided on the partitions 32 in the water reservoir 3, and the ultraviolet lamps 321 play a role in sterilizing and disinfecting the water.
[0037] The implementation principle of the hot water recovery device for wet-splitting in the pulp tank of the embodiment of the present application is as follows: when in use, the three-way solenoid valve 6 controls the first water inlet 61 to be connected to the external water source through the first pipe 62, and the pump 4 is started to pump the external water source into the water reservoir 3 after passing through the wet-splitting rod 2. When the water in the water reservoir 3 is full, the three-way solenoid valve 6 controls the second water inlet 63 to be connected to the water reservoir 3 through the second pipe 64, and the pump 4 is started to pump the water in the water reservoir 3 into the wet-splitting rod 2 through the water inlet pipe 21, and the refrigerator 5 works at the same time to cool the water in the water inlet pipe 21, thereby improving the wet-splitting effect of the wet-splitting rod 2. The water flowing out of the wet-splitting rod 2 flows back into the water reservoir 3 through the water outlet pipe 22 to form a water flow cycle, thereby reducing the supply of water and saving water resources. When water flows in the wet wringing rod 2, it drives the impeller 24 to rotate, drives the rotating shaft 23 to rotate, and drives the cleaning brush 25 to clean the scale and other impurities attached to the inner wall of the wet wringing rod 2, thereby further improving the wet wringing effect of the wet wringing rod 2. In addition, the partition 32 is set to divide the water reservoir 3 into three sedimentation tanks 33, and the impurities in the water are precipitated through multi-stage sedimentation, and then the precipitated impurities are discharged through the silt removal pipe 7 by regularly starting the silt removal pump 71, further reducing the probability of impurities adhering to the inner wall of the wet wringing rod 2 and improving the wet wringing effect.
[0038] The above are all optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
