Description

Technical Field

[0001] This utility model relates to the field of crystallization technology, specifically to a crystallization device for preparing fluorescent whitening agents. Background Technology

[0002] Fluorescent brighteners are fluorescent dyes, also known as white dyes, and are a general term for a class of compounds. Their characteristic is that they can excite incident light to produce fluorescence, giving the dyed material a sparkling effect similar to fluorite, making the material appear very white to the naked eye. During the processing of fluorescent brighteners, a crystallization device is required to precipitate the crystals.

[0003] Chinese Patent Publication No. CN 222342026 U discloses a utility model patent entitled "A Crystallization Membrane Equipment for Preparing Fluorescent Whitening Agents," belonging to the field of fluorescent whitening agent processing technology. The device includes a tank, with a protective frame fixedly connected to the top of the tank. A first motor and a second motor are fixedly connected to the bottom of the protective frame. A rotating shaft is fixedly connected to the output end of the first motor, and the bottom end of the rotating shaft passes through the tank and is fixedly connected to a first stirring frame. Its advantages are that by setting up the first motor, the first stirring frame, the second motor, and the second stirring frame, the raw materials and water are stirred synchronously in opposite directions, allowing for thorough mixing and better crystallization. It also cleans materials adhering to the side walls of the tank. A guide plate and a discharge port are used to clean materials from the bottom of the inner wall of the tank. After crystallization, the crystals are exported. A heater and heating elements are used for auxiliary heating during crystallization.

[0004] However, in actual use, the above-mentioned equipment lacks corresponding temperature control methods after stirring the raw materials and water with auxiliary heating to carry out the molding operation. After the work is stopped, the equipment will still maintain a high internal temperature for a period of time, which will accelerate the aging and corrosion of the equipment materials. Utility Model Content

[0005] The purpose of this invention is to provide a crystallization membrane device for preparing fluorescent whitening agents, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a crystal film precipitation device for preparing fluorescent whitening agents, including a temperature control mechanism, an adjustment mechanism being provided at the bottom of the temperature control mechanism, and the top of the adjustment mechanism being fixedly connected to the bottom of the temperature control mechanism;

[0007] The temperature control mechanism includes a crystallization membrane device body, a heat-conducting sleeve is fitted at the bottom of the crystallization membrane device body, a support frame is fixedly connected to the bottom of the heat-conducting sleeve, a base plate is provided at the bottom of the support frame, a wind frame is fixedly connected to the outside of the base plate, and a first fan is fixedly connected to the inside of the wind frame.

[0008] The internal temperature is dissipated by a heat-conducting jacket, spreading the internal temperature evenly with the jacket. The jacket is fixed above the base plate by a support frame, and the gaps at the bottom increase the contact area with the outside natural wind, thus accelerating the heat exchange rate with the air.

[0009] Preferably, the base plate has a first sliding groove inside, which is adapted to the support frame. The base plate also has a second sliding groove inside, and a connecting plate is provided inside the second sliding groove. There are two support frames. The left and right sides of the connecting plate are fixedly connected to the support frames respectively. A second fan is fixedly connected inside the connecting plate.

[0010] Preferably, a heat sink is fixedly connected to the outer side of the heat-conducting sleeve, and multiple heat sinks are provided, with the bottom of each heat sink being adapted to the output port of the same first fan.

[0011] Preferably, the adjustment mechanism includes multiple electric tension rods arranged in a circular array around the base plate. The tops of the multiple electric tension rods are fixedly connected to the bottom of the same base plate, and the bottoms of the multiple electric tension rods are fixedly connected to rubber pads. The bottoms of the multiple rubber pads are fixedly connected to self-locking casters.

[0012] Preferably, a fixing plate is fixedly connected to the outer side of the base plate, a bearing is fixedly connected to the outer side of the fixing plate, a handle is rotatably connected inside the bearing, and an anti-slip sleeve is provided on the surface of the handle.

[0013] The handle inside the bearing allows for easier movement, and when not in use, it can be naturally drooped down to reduce space occupation.

[0014] Preferably, a cylinder is fixedly connected to the bottom of the base plate, and a support plate is fixedly connected to the bottom of the cylinder.

[0015] Preferably, the cylinder is provided with a push rod inside, the top of the push rod is fixedly connected to the bottom of the second fan, and the push rod is adapted to the second slide groove.

[0016] The height of the upper equipment can be adjusted by the cylinder. When working and not requiring heat dissipation, the support frame can be retracted into the first and second slides inside the base plate by retracting the push rod, reducing the heat dissipation area to the outside and preventing heat loss.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] Firstly, this utility model operates through the crystal precipitation device body. A heat-conducting sleeve distributes the internal temperature evenly across the device. It is fixed to the base plate by a support frame, and the gaps at the bottom increase the contact area with external natural air, accelerating heat exchange. A first fan inside the frame blows air onto the heat sinks to further accelerate heat dissipation. During normal operation, the first and second fans are not activated; the internal temperature is distributed solely through the heat sinks and heat-conducting sleeve. This allows operators to easily determine the internal temperature using external equipment and prevents excessive internal temperature. After operation or when the internal temperature is too high and affects crystal precipitation efficiency, the first and second fans can be activated simultaneously to dissipate heat from the bottom and surface. This solves the problem of the lack of corresponding temperature control methods, where the device retains a high internal temperature for a period after operation, accelerating material aging and corrosion.

[0019] Secondly, this utility model uses an electric extension rod to adjust the height of the base plate and self-locking casters at the bottom of the rubber pad to move the equipment. When the equipment does not need to be moved, the electric extension rod can be lowered to retract the self-locking casters upwards, and the support plate under the cylinder at the bottom of the base plate can support them, allowing the casters to float in the air. The handle inside the bearing allows for more convenient movement. When not in use, the casters can be naturally lowered to reduce space occupation. The cylinder can adjust the height of the equipment above. When working and not requiring heat dissipation, the push rod can be retracted to allow the support frame to retract into the first and second sliding grooves inside the base plate, reducing the heat dissipation area to the outside and preventing heat loss.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1 , Figure 2 A crystallization membrane preparation device for fluorescent whitening agent includes a temperature control mechanism 1, an adjustment mechanism 2 is provided at the bottom of the temperature control mechanism 1, and the top of the adjustment mechanism 2 is fixedly connected to the bottom of the temperature control mechanism 1.

[0029] The temperature control mechanism 1 includes a crystallization membrane device body 101. A heat-conducting sleeve 102 is fitted on the bottom of the crystallization membrane device body 101. A support frame 103 is fixedly connected to the bottom of the heat-conducting sleeve 102. A base plate 104 is provided at the bottom of the support frame 103. A fan frame 106 is fixedly connected to the outside of the base plate 104. A first fan 107 is fixedly connected to the inside of the fan frame 106.

[0030] The base plate 104 has a first sliding groove inside, which is adapted to the support frame 103. The base plate 104 has a second sliding groove inside, and a connecting plate 108 is provided inside the second sliding groove. There are two support frames 103. The left and right sides of the connecting plate 108 are fixedly connected to the support frame 103 respectively. A second fan 109 is fixedly connected inside the connecting plate 108.

[0031] Heat sinks 105 are fixedly connected to the outer side of the heat-conducting sleeve 102. Multiple heat sinks 105 are provided, and the bottom of each heat sink 105 is adapted to the output port of the same first fan 107.

[0032] Through the above technical solution, the crystal precipitation equipment body 101 operates, and the internal temperature is dissipated through the heat-conducting sleeve 102, spreading the internal temperature evenly with the heat-conducting sleeve 102. It is fixed above the base plate 104 by the support frame 103, and the gap at the bottom increases the contact area with the outside natural wind, accelerating the heat exchange speed with the air. The first fan 107 inside the wind frame 106 blows the heat sink 105 to accelerate the heat dissipation speed, which can further accelerate the heat dissipation speed. During normal operation, the first fan 107 and the second fan 109 do not work. The internal temperature is spread evenly by the heat sink 105 and the heat-conducting sleeve 102. On the one hand, it is convenient for the staff to determine the internal temperature through external equipment, and on the other hand, it can prevent the internal temperature from being too high. After the work is completed or when the internal temperature is too high and affects the crystal precipitation efficiency, the first fan 107 and the second fan 109 can be turned on to dissipate heat from the bottom and the surface at the same time. This solves the problem of the lack of corresponding temperature control means, which prevents the equipment from maintaining a high internal temperature for a period of time after the work is stopped, which will accelerate the aging and corrosion of the equipment materials.

[0033] Example 2

[0034] Please see Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the adjustment mechanism 2 includes an electric tension rod 201. Multiple electric tension rods 201 are provided, arranged in a circular array around the base plate 104. The tops of the multiple electric tension rods 201 are fixedly connected to the bottom of the same base plate 104, and rubber pads 202 are fixedly connected to the bottoms of the multiple electric tension rods 201. Self-locking casters 203 are fixedly connected to the bottoms of the multiple rubber pads 202.

[0035] A fixing plate 204 is fixedly connected to the outer side of the base plate 104, and a bearing 205 is fixedly connected to the outer side of the fixing plate 204. A handle 206 is rotatably connected inside the bearing 205, and an anti-slip sleeve 207 is sleeved on the surface of the handle 206.

[0036] A cylinder 208 is fixedly connected to the bottom of the base plate 104, and a support plate 210 is fixedly connected to the bottom of the cylinder 208.

[0037] The cylinder 208 has a push rod 209 inside. The top of the push rod 209 is fixedly connected to the bottom of the second fan 109, and the push rod 209 is adapted to the second slide groove.

[0038] Through the above technical solution, the height of the base plate 104 is adjusted by the electric extension rod 201, and the position of the equipment is moved by the self-locking casters 203 at the bottom of the rubber pad 202. When the equipment does not need to be moved, the electric extension rod 201 can be lowered to retract the self-locking casters 203 upwards. The support plate 210 under the cylinder 208 at the bottom of the base plate 104 provides support, allowing the self-locking casters 203 to float in the air. The handle 206 inside the bearing 205 allows for more convenient movement. When not in use, it can be naturally lowered to reduce space occupation. The height of the equipment above can be adjusted by the cylinder 208. When working and not requiring heat dissipation, the support frame 103 can be retracted into the first and second sliding grooves inside the base plate 104 by retracting the push rod 209, reducing the heat dissipation area to the outside and preventing heat loss.

[0039] In actual operation, when this device is in use, it operates through the crystallization membrane equipment body 101. The internal temperature is dissipated through the heat-conducting sleeve 102, spreading the internal temperature evenly across the sleeve. It is fixed above the base plate 104 by the support frame 103. The gap at the bottom increases the contact area with external natural air, accelerating heat exchange with the air. The first fan 107 inside the air frame 106 blows air onto the heat sink 105, further accelerating heat dissipation. During normal operation, the first fan 107... The first fan 107 and the second fan 109 do not work. The internal temperature is spread out by the heat sink 105 and the heat-conducting sleeve 102. This allows the staff to easily determine the internal temperature through external equipment and avoids the internal temperature from getting too high. After the work is completed or when the internal temperature is too high and affects the crystal precipitation efficiency, the first fan 107 and the second fan 109 can be turned on to dissipate heat from the bottom and the surface at the same time. This solves the problem that the equipment will still maintain a high internal temperature for a period of time after the work is stopped, which will accelerate the aging and corrosion of the equipment materials. The height of the base plate 104 is adjusted by the electric extension rod 201, and the position of the equipment is moved by the self-locking casters 203 at the bottom of the rubber pad 202. When the equipment does not need to be moved, the electric extension rod 201 can be lowered to retract the self-locking casters 203 upwards. The support plate 210 under the cylinder 208 at the bottom of the base plate 104 provides support, allowing the self-locking casters 203 to float in the air. The handle 206 inside the bearing 205 allows for more convenient movement. When not in use, it can be naturally lowered to reduce space occupation. The height of the equipment above can be adjusted by the cylinder 208. When working and not requiring heat dissipation, the support frame 103 can be retracted into the first and second sliding grooves inside the base plate 104 by retracting the push rod 209, reducing the heat dissipation area to the outside and preventing heat loss.
