Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dye liquor circulating pumps, and particularly relates to a precise dye liquor circulating pump. BACKGROUND

[0002] The printing and dyeing industry, also known as the dyeing and finishing industry, is an intermediate link in the textile industry chain, connecting the upstream textile fibers and the downstream textile and garment industry. The industry takes cotton, wool, silk, hemp and chemical fibers as processing carriers, and gives fabrics color, patterns and specific functions through a series of processes such as pretreatment, dyeing, printing and post-finishing. The processing flow is flexibly adjusted according to the characteristics of raw materials and product requirements. The core is to improve the appearance and practicality of textiles through professional technology, increase the added value of products, cover all types of textile fabric processing, and widely apply to the fields of clothing and home supplies. At the same time, it pays attention to process optimization and environmental upgrading, and plays a key role in function giving and quality improving in the textile industry.

[0003] The dye liquor circulating pump is a core fluid conveying equipment in the printing and dyeing industry, which is designed for dyeing process. Its core function is to promote the stable circulation of dye liquor in the dyeing equipment. The equipment is suitable for various dye liquor media and can ensure uniform coverage of the fabric by the dye liquor, avoiding uneven dyeing and color spots. It provides a stable process environment for fabric dyeing. It has the characteristics of resistance to dye liquor corrosion and reliable sealing, and can adapt to the working conditions in the printing and dyeing production to prevent dye liquor leakage and ensure production safety and workshop cleanliness. At the same time, the equipment is convenient to maintain, which can reduce production interruption and help improve dyeing efficiency and product quality. It is widely used in textile dyeing processing and is a key equipment to ensure the stability of printing and dyeing process and product consistency.

[0004] In the existing technology, the dye liquor circulating pump is usually composed of a driving assembly, a flow channel component and a sealing device. Although this dye liquor circulating pump can promote the circulation of dye liquor, it does not have a dye liquor pre-pressurization and dye liquor carding mechanism. When the dye liquor level is low, water pressure deficiency and flow disorder may occur at the pump inlet. Water pressure deficiency may cause air bubble cavities in the pump body, aggravating the gas corrosion of the pump body. The disorderly flow of dye liquor at the pump inlet may increase the flow resistance and make it difficult for the dye liquor to enter the pump body smoothly and orderly. In addition, the existing dye liquor circulating pump does not have an efficient active cooling structure, but relies on the motor shell for passive cooling. Although it has a certain cooling effect, the cooling efficiency is low. When the temperature is high in summer or the dye liquor circulating pump works continuously for a long time, the pump body may overheat. At this time, the pump body needs to be stopped for cooling. Therefore, some manufacturers configure multiple sets of dye liquor circulating pumps to ensure uninterrupted printing and dyeing processing, resulting in increased equipment cost of printing and dyeing. SUMMARY

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a precision dyeing solution circulation pump.

[0006] The technical solution adopted to solve the above technical problems is: a precision dye liquor circulation pump, including a motor mechanism and a valve mechanism. The motor mechanism includes a motor body, a temperature controller is fixed at one end of the motor body, a housing mechanism is fixed at the output end of the motor mechanism, a cover plate mechanism is bolted to the housing mechanism, and an impeller mechanism is rotatably connected to the inner side of the housing mechanism.

[0007] One end of the impeller mechanism is inserted and fixed with a turbine mechanism, which includes multiple turbine blades fixed in a ring array. A stainless steel ring is fixed to the outside of the turbine blades. A filter cover mechanism is snapped and fixed to the inside of the cover plate mechanism. The filter cover mechanism includes a steel wire filter screen.

[0008] A valve mechanism is fixed to the top of the housing mechanism. The valve mechanism includes an electronic three-way valve fixed to the top of the pump outlet. A cooling mechanism is attached to the outside of the motor mechanism. The cooling mechanism includes a metal heat sink. Multiple heat sink fins are integrally fixed to the outside of the metal heat sink. Liquid cooling pipes are inserted and fixed to the inside of the heat sink fins.

[0009] Furthermore, the motor body has multiple heat dissipation slots, the output end of the motor body is rotatably connected to a motor output shaft, and the bottom of the motor body is fixed with at least two fixed support legs.

[0010] Through the above technical solution, the temperature controller's detection sensor is attached to the motor body housing, and the temperature controller can detect the temperature of the motor body. The heat dissipation slots effectively increase the heat dissipation area of ​​the motor body, thereby improving the heat dissipation efficiency of the motor body. One of the fixed support feet can be used to fix the motor body. The end of the motor output shaft is hexagonal prism-shaped. When the motor body is powered on, the motor output shaft will rotate.

[0011] Furthermore, the housing mechanism includes a housing body fixed to the motor body, a bearing mounting groove on the housing body, two fixed support legs integrally connected to the bottom of the housing body, multiple fixed lugs integrally connected to the housing body, and a pump outlet integrally connected to the top of the housing body.

[0012] With the above technical solution, the housing body is a cover-shaped structure, the bearing mounting groove allows the motor output shaft to pass through, and the second fixed support foot can be used to fix the housing body, thereby improving the stability of the device.

[0013] Furthermore, the cover plate mechanism includes a cover body that is sealed to the housing body. A pump inlet is integrally fixed on the cover body. A first bearing is fixed on the inner side of the pump inlet. The inner ring of the first bearing is fixed to a stainless steel ring. Multiple fixing lugs are integrally connected on the cover body. Multiple insertion slots are provided on the inner side of the pump inlet.

[0014] With the above technical solution, the position and number of fixed ears are matched with fixed ears one. The staff can fix fixed ears one and fixed ears two together with bolts, thereby fixing the shell body and the cover body. Multiple plug slots are distributed in a ring at equal intervals.

[0015] Furthermore, the impeller mechanism includes an impeller back plate sleeved on the motor output shaft, an internal hexagonal slot on the impeller back plate, a second bearing fixed at one end of the impeller back plate, multiple pump blades integrally connected to the other end of the impeller back plate, a shaft integrally fixed at the center of the impeller back plate, a pin hole on the shaft, and the outer ring of the second bearing fixed to the inner wall of the bearing mounting groove.

[0016] Through the above technical solution, the outer ring of the second bearing is fixed to the inner wall of the bearing mounting groove, and the internal hexagonal socket is sealed and rotatably connected to the bearing mounting groove. The specifications of the internal hexagonal socket match the motor output shaft, and the motor output shaft is inserted into the inner side of the internal hexagonal socket. When the motor body starts, the motor body drives the motor output shaft and the impeller back plate to rotate, thereby causing the pump blades to rotate, and then pumping the dye liquor out through the pump outlet.

[0017] Furthermore, the turbine mechanism includes an internal hexagonal socket sleeve fitted onto the shaft, and a fixing pin is provided on the internal hexagonal socket sleeve.

[0018] Through the above technical solution, the hexagonal socket is inserted and fixed to the shaft, and the fixing pin passes through the pin hole, which can effectively prevent the hexagonal socket from separating from the shaft. When the impeller mechanism rotates, multiple turbine blades will also rotate, thereby pushing the dye liquid at the pump inlet into the housing body. In addition, multiple turbine blades can effectively pre-pressurize the dye liquid in the housing body, avoid the formation of local gas cavities in the housing body, thereby reducing gas corrosion. They can also sort the turbulent flow at the pump inlet into axial liquid flow, thereby improving the stability of the impeller mechanism. The stainless steel ring is fixed to the inner ring of the first bearing. The first bearing and the second bearing together limit the impeller mechanism and the turbine mechanism, thereby keeping the axis of the impeller mechanism and the turbine mechanism stable at all times, further improving the stability of the device, reducing the shaking of the device, and reducing energy loss.

[0019] Furthermore, the filter cover mechanism includes a metal retaining ring fitted inside the pump inlet, the metal retaining ring having multiple buckles fixed on it, and the metal retaining ring being fixed to the wire mesh filter.

[0020] With the above technical solution, the position, quantity, and specifications of the buckles are all matched with the insertion slots. Workers can insert the buckles into the insertion slots to secure the metal clips and wire mesh to the device. The wire mesh can filter out large particles and impurities in the dye liquor, thereby improving the service life of the device.

[0021] Furthermore, the bottom of the electronic three-way valve is fixed with a water inlet, the top of the electronic three-way valve is fixed with a first liquid outlet, and one side of the electronic three-way valve is fixed with a second liquid outlet.

[0022] With the above technical solution, the water inlet is sealed to the pump outlet, and the electronic three-way valve is electrically connected to the temperature controller. Under normal conditions, only the first outlet of the electronic three-way valve is open. When the temperature controller detects that the motor body is overheated, the second outlet of the electronic three-way valve will also open.

[0023] Furthermore, the metal heat sink is fitted onto the outside of the motor body, and both the metal heat sink and the heat sink fins are made of aluminum alloy, while the liquid cooling pipes are made of copper.

[0024] Through the above technical solution, the metal heat sink is hoop-shaped, and its inner wall shape fits the outer wall of the motor body and the shape of the heat sink groove. The heat of the motor body can be effectively conducted to the heat sink fins through the metal heat sink, thereby increasing the heat dissipation area of ​​the motor body and improving the heat dissipation effect of the motor body. The aluminum alloy metal heat sink and heat sink fins have good thermal conductivity and light weight, and the copper liquid cooling pipeline has better thermal conductivity, thus facilitating the rapid removal of heat by the dyeing liquid.

[0025] Furthermore, the electronic three-way valve is electrically connected to the temperature controller, and the two ends of the liquid cooling pipeline are respectively sealed to the second liquid outlet and the first liquid outlet.

[0026] With the above technical solution, one end of the liquid cooling pipeline is sealed to the second liquid outlet, and the other end of the liquid cooling pipeline is connected to the first liquid outlet. The middle section of the liquid cooling pipeline spirals through the space between multiple heat dissipation fins. When the second liquid outlet of the electronic three-way valve is opened, some dye liquid will enter the liquid cooling pipeline from the second liquid outlet, thereby taking away the heat on the heat dissipation fins and further cooling the motor body.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. The present invention, through the arrangement of a first bearing, an impeller back plate, pump blades, a second bearing, turbine blades and a stainless steel ring, enables the device to pre-pressurize and comb the dye liquor entering the pump body, thereby effectively avoiding the formation of air chambers in the pump body, reducing gas corrosion, increasing the flow rate of dye liquor, and also improving the stability of the device.

[0029] 2. By incorporating a temperature controller, an electronic three-way valve, a metal heat sink, heat sink fins, and liquid cooling pipes, this invention effectively increases the heat dissipation area of ​​the motor, thereby improving the heat dissipation rate. When the motor overheats, the device can also perform liquid cooling to further improve the heat dissipation rate.

[0030] 3. By incorporating a first bearing, a second bearing, and a steel wire filter, this invention effectively reduces vibration during operation and filters impurities and large particles in the dye liquor, thereby extending the device's service life. Attached Figure Description

The specifications of the internal hexagonal socket 402 match the motor output shaft 104, and the motor output shaft 104 is inserted into the inner side of the internal hexagonal socket 402. When the motor body 101 starts, the motor body 101 drives the motor output shaft 104 and the impeller back plate 401 to rotate, thereby causing the pump blades 404 to rotate, and then pumping the dye liquor out through the pump outlet 205.

The water inlet 702 is sealed to the pump outlet 205. The electronic three-way valve 701 is electrically connected to the temperature controller 103. Under normal conditions, only the first outlet 703 of the electronic three-way valve 701 is open. When the temperature controller 103 detects the motor body 10... 1. When overheating occurs, the second outlet 704 of the electronic three-way valve 701 will also open. The cooling mechanism 8 includes a metal heat sink 801, with multiple heat dissipation fins 802 integrally fixed to the outside of the metal heat sink 801. Liquid cooling pipes 803 are inserted and fixed to the inside of the heat dissipation fins 802. The metal heat sink 801 is fitted to the outside of the motor body 101. Both the metal heat sink 801 and the heat dissipation fins 802 are made of aluminum alloy, and the liquid cooling pipes 803 are made of copper. The electronic three-way valve 701 is electrically connected to the temperature controller 103, and the liquid cooling pipes 803... The two ends of 3 are respectively sealed and connected to the second liquid outlet 704 and the first liquid outlet 703.

The aluminum alloy metal heat dissipation sleeve 801 and heat dissipation fins 802 have good thermal conductivity and light weight, while the copper liquid cooling pipe 803 has even better thermal conductivity, thus facilitating the rapid removal of heat by the dye liquid.

[0047] The working principle of this embodiment is as follows: The operator can install the device on the wall of an open dyeing vat, connecting the pump inlet 302 to the vat, and then connecting the circulation pipeline to the first outlet 703. When the motor body 101 starts, it drives the motor output shaft 104 and the impeller back plate 401 to rotate, causing the pump blades 404 to rotate. This pumps the dye liquor through the pump outlet 205 and transports it to the dyeing vat through the circulation pipeline, thus achieving dye liquor circulation. When the impeller mechanism 4 rotates, multiple turbine blades 503 also rotate, pushing the dye liquor at the pump inlet 302 into the housing body 201. The multiple turbine blades 503 effectively pre-pressurize the dye liquor within the housing body 201, preventing the formation of localized gas cavities and reducing gas corrosion. They also streamline the turbulent flow at the pump inlet 302 into an axial flow, thereby improving the stability of the impeller mechanism 4. The device can operate normally even when the dye liquor level is low or the water pressure is insufficient. The filter cover mechanism 6 can filter out impurities and large particles in the dye liquor, thereby reducing the wear of the device and improving its service life. The metal heat sink 801 and heat sink 802 can effectively improve the heat dissipation rate of the device. When the weather is hot or the device is overheated due to continuous long-term operation, the temperature controller 103 detects that the motor body 101 is overheated, and the second outlet 704 of the electronic three-way valve 701 will open. Some of the dye liquor will enter the liquid cooling pipe 803 from the second outlet 704, thereby carrying away the heat on the heat sink 802, and further cooling the motor body 101. The aluminum alloy metal heat sink 801 and heat sink 802 have good thermal conductivity and light weight, and the copper liquid cooling pipe 803 has better thermal conductivity, which facilitates the rapid removal of heat by the dye liquor, allowing the device to temporarily reduce the head to achieve a faster heat dissipation effect.
