Description

Technical Field

[0001] The invention belongs to the technical field of cellulose fiber production, and in particular relates to a high-temperature water safety recycling device. Background Art

[0002] Cellulose fiber, also known as artificial fiber, is a fiber material made by reshaping cellulose molecules extracted from natural substances through a specific process. Cellulose fiber has good moisture absorption and air permeability, which gives it a significant advantage in the textile field. Clothing made of cellulose fiber can absorb sweat discharged from the human body and keep the skin dry. At the same time, it has good air permeability to prevent stuffiness. Cellulose fiber is most widely used in the textile field and can be used to make various types of underwear, coats, bedding, non-woven fabrics, etc. Its excellent moisture absorption, air permeability and natural skin-friendliness make cellulose fiber products popular among consumers in the market.

[0003] After searching, in the prior art, Chinese patent announcement number: CN213328448U, authorization date: 2021-06-01, discloses a cellulose pulping device, including a drive motor, a reducer, a coupling, a connecting bracket, a stirring tank body, a leg, an anchor frame paddle and a stirring shaft. The drive motor is a variable frequency motor. The drive motor drives the stirring shaft to rotate through the reducer and the coupling. The anchor frame paddle is fixed to the end of the stirring shaft. The connecting bracket is fixed between the reducer and the stirring tank body. The stirring tank body is located at the lower part of the connecting bracket. The upper closed cover body, the barrel body, and the lower closed cover body form a stirring chamber. The legs are fixed to the lower side of the lower closed cover body. The stirring shaft passes through the upper closed cover body. The anchor frame paddle is accommodated in the stirring chamber, and the anchor frame paddle is located at the lower part of the stirring chamber. Through the operation of the drive motor, the anchor frame paddle is stirred at a variable frequency speed regulation of 0 to 300 rpm to achieve a high solid content pulping effect. A double-fulcrum bracket is used. The stirring shaft has been dynamically balanced. The equipment stirs smoothly without obvious vibration.

[0004] However, the device still has the following defects: although it can effectively improve the problem in the prior art that if a high-speed dispersing blade such as a dispersion disk is used, it is easy to cut the cellulose cell structure, but most of the existing cellulose fibers often need to undergo most processing steps during production, such as drying, acid station flash evaporation, crystallization, pulping, etc., and a large amount of steam is usually used during the above steps, and the use of steam will produce a large amount of high-temperature steam condensate. When the high-temperature steam condensate is recovered and reused, it is easy to cause burns to the staff or cause certain damage to the equipment due to improper operation and other factors.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The embodiment of the present invention provides a high temperature water safety recycling device, including a buffer tank 1, exemplarily, as Figure 1 and Figure 2 shown.

[0027] A cover plate 2 is provided on the upper side of the buffer tank 1, a connecting pipe 31 and a water inlet pipe 36 are fixedly connected to the inner side of the buffer tank 1, a water pump 32 is provided on the outer side of the connecting pipe 31, one end of the connecting pipe 31 is fixedly connected to a heat exchanger 33, one end of the heat exchanger 33 away from the connecting pipe 31 is fixedly connected to a connecting pipe 34, one end of the connecting pipe 34 away from the heat exchanger 33 is fixedly connected to a water tank 35, an inner side of the water tank 35 is fixedly connected to a water outlet pipe 37, a valve body 38 is provided on the outer side of the water outlet pipe 37, a protective component 5 is provided on the upper side of the cover plate 2, a control component 4 is provided on the upper side of the heat exchanger 33, and a stirring component 6 is provided on the outer side of the cover plate 2.

[0028] The protection assembly 5 includes a pressure detection gauge 51 and an air outlet pipe 52 fixedly connected to the inner side of the cover plate 2 , and a pressure relief valve 53 is arranged on the outer side of the air outlet pipe 52 .

[0029] The control assembly 4 includes a controller 41 and a temperature detector 42 fixedly connected to the upper side of the heat exchanger 33 , and the controller 41 and the temperature detector 42 are electrically connected.

[0030] Specifically, the buffer tank 1 can play a certain role in treating the high-temperature steam condensate. The staff can add water to the inside of the buffer tank 1 through the water inlet pipe 36 to cool it down to a certain extent. The water pump 32 can pump the cooled steam condensate into the inside of the connecting pipe 31 through its own operation, and the condensate can be smoothly pumped into the inside of the heat exchanger 33 through the connecting pipe 31, so that the condensate can be further cooled through the heat exchanger 33.

[0031] In addition, the cooled condensed water will flow into the inner side of the water storage tank 35 through the connecting pipe 34, which is convenient for the staff to process and use it. The setting of the water outlet pipe 37 makes it convenient for the staff to take out the cooled steam condensed water, and the valve body 38 can open or close the flow of the water outlet pipe 37.

[0032] In addition, the temperature detector 42 can detect the temperature of the condensed water being exchanged inside the heat exchanger 33. When the temperature reaches 60 degrees Celsius, the condensed water is discharged through the controller 41, so as to facilitate the subsequent use of the condensed water and prevent the steam condensed water from causing burns to the staff during subsequent use. At the same time, the pressure detection gauge 51 can detect the air pressure inside the buffer tank 1. When the air pressure is too high, the staff can release the air pressure inside the buffer tank 1 through the outlet pipe 52 and the pressure relief valve 53 to reduce the possibility of damage to the buffer tank 1.

[0033] The stirring assembly 6 includes a servo motor 61 fixedly connected to the upper side of the cover plate 2, and the output end of the servo motor 61 passes through the cover plate 2. Figure 1 and Figure 2 shown.

[0034] The output end of the servo motor 61 is connected to a rotating rod 62 through a coupling. A stirring block 63 is arranged on the outer side of the rotating rod 62 , and the stirring block 63 is arranged on the inner side of the buffer tank 1 .

[0035] A first temperature display 71 is fixedly connected to the inner side of the cover plate 2 , a second hinge plate 9 is movably hinged to the upper side of the water storage tank 35 via a hinge, and a second temperature display 72 is fixedly connected to the inner side of the second hinge plate 9 .

[0036] The water tank 35 has an installation groove 111 formed inside thereof. A heating plate 112 is disposed inside the installation groove 111 . The outer side of the heating plate 112 is fixedly connected to the water tank 35 .

[0037] Specifically, the servo motor 61 can drive the stirring block 63 to rotate when in operation, so that when the cooling water source contacts the high-temperature steam condensate, the two can be stirred by the rotation of the stirring block 63, so that the cooling effect of the cooling water source on the high-temperature steam condensate can be better and more uniform;

[0038] In addition, the setting of the first temperature display 71 can facilitate the staff to observe the temperature of the high-temperature steam condensate inside the buffer tank 1, while the second temperature display 72 can facilitate the staff to observe the temperature of the cooled condensate;

[0039] In addition, when the temperature of the cooled high-temperature steam condensate stored in the water tank 35 drops significantly due to long-term storage, the staff can heat the water source through the operation of the heating plate 112, so that the cooled condensate can be maintained at around 60 degrees Celsius, thereby facilitating the subsequent use of the condensate.

[0040] A filter box 81 is disposed outside the water inlet pipe 36. A first hinge plate 82 is movably hinged on the upper side of the filter box 81. A filter screen 83 is disposed inside the filter box 81. Figure 1 and Figure 2 shown.

[0041] The inner side of the filter box 81 is fixedly connected with a limit plate 10 , and the limit plate 10 is arranged on the outer side of the filter screen 83 . The lower side of the filter box 81 is fixedly connected with a reinforcement plate 12 , and one side of the reinforcement plate 12 is fixedly connected to the buffer tank 1 .

[0042] Specifically, the filter box 81 can be connected to the filter screen 83, and the filter screen 83 can filter the water source used for cooling, thereby reducing the impurities inside it, so that the water source finally collected inside the water storage tank 35 can be relatively clean;

[0043] In addition, the limiting plate 10 can provide certain support and limitation to the filter net 83, so that it is sufficiently stable when in use and is not prone to falling or shaking. At the same time, the reinforcing plate 12 can support and reinforce the filter box 81, so that the filter box 81 is sufficiently stable when in use and is not prone to falling or the like.

[0044] The working principle of a high-temperature water safety recycling device proposed in an embodiment of the present invention is as follows:

[0045] When the device is in use, the staff can introduce the water source for cooling into the inner side of the buffer tank 1 through the water inlet pipe 36. The water source will be filtered by the filter 83 when introduced. Then the staff can start the servo motor 61, and drive the rotating rod 62 and the stirring block 63 to rotate through the coupling. The stirring block 63 stirs the cooling water source and the high-temperature steam condensate in the buffer tank 1 to improve the cooling efficiency. After that, the water source inside the buffer tank 1 can be pumped into the inner side of the heat exchanger 33 through the water pump 32. The heat exchanger 33 will further heat and cool the high-temperature steam condensate. When the temperature reaches 60 degrees Celsius, the controller 41 sends a signal to enable the condensate inside the heat exchanger 33 to flow smoothly into the inner side of the water storage tank 35 through the connecting pipe 34. When the condensate is needed, the valve body 38 is opened to take the condensate out of the water storage tank 35 through the outlet pipe 37.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
