Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and particularly relates to a temperature-controllable oil tank. Background Art

[0002] In the field of textiles, some yarn materials have low lubricity and high friction. During the weft threading process in the textile process, the warp and weft yarns are prone to pulling each other, and a large amount of heat is generated in this process, posing a production risk.

[0003] In order to solve this problem, the commonly used method is to lubricate the yarn before weaving, and run the yarn over an oil roller half immersed in an oil tank, and apply the oil to the yarn through the oil roller.

[0004] However, the viscosity of the oil itself is easily affected by temperature. It becomes thinner at high temperatures and thicker at low temperatures. Whether it is thin oil or thick oil, it is not suitable for lubricating the yarn. Therefore, the existing technology often uses some heating or cooling equipment to control the temperature of the oil, but both have some disadvantages. Specifically, they are as follows: 1. Oil radiators / electric heating rods. Both of them have a single function and can only cool or heat. Even if they are used in combination, the oil radiator and electric heating rod themselves do not have the ability to circulate oil, and an additional circulation power source such as an oil pump is required. Without circulation power, the oil radiator is basically useless, and the electric heating rod will cause the surrounding oil to prematurely denature (carbonize) at high temperature. 2. Oil coolers. Oil coolers are equipment that can cool and heat, but they are relatively expensive and require the use of refrigerants. Daily maintenance is also troublesome and takes up additional space. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a temperature-controllable oil tank, which is used to solve the technical problems in the prior art of equipment for controlling the temperature of the oil tank, such as insufficient temperature control capability or inconvenience in use.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: a temperature-controllable oil tank, comprising:

[0007] An oil tank body, wherein the side and bottom surfaces of the oil tank body are provided with a plurality of slots;

[0008] A plurality of semiconductor refrigeration sheets, wherein the plurality of semiconductor refrigeration sheets are respectively inserted into the slots, and the slots are adapted to the semiconductor refrigeration sheets;

[0009] A controller, wherein the controller is electrically connected to a plurality of the semiconductor refrigeration chips, and the plurality of the semiconductor refrigeration chips are connected in parallel;

[0010] A temperature sensor is provided in the oil tank body and is electrically connected to the controller.

[0011] The utility model utilizes a semiconductor refrigeration chip as a cold and heat source, attaches the semiconductor refrigeration chip to the outer wall of the oil tank body, and heats or cools by switching the positive and negative poles of the direct current input into the semiconductor refrigeration chip, thereby achieving the purpose of controlling the oil temperature in the oil tank body.

[0012] Furthermore: a heat-conducting medium is coated between the semiconductor refrigeration plate and the slot.

[0013] The beneficial effect of adopting this step is: improving heat transfer efficiency through the heat-conducting medium.

[0014] Furthermore: the controller is electrically connected to an AC / DC converter, and the positive and negative output ends of the AC / DC converter are both provided with single-pole double-throw relays, and the two single-pole double-throw relays are respectively electrically connected to the parallel circuits of several semiconductor refrigeration plates.

[0015] The beneficial effect of this step is: the AC / DC converter has the function of converting alternating current into direct current, but the AC / DC converter only has single-polarity direct current. By controlling the energized state of the two single-pole double-throw relays, opposite direct currents are provided respectively to control whether the semiconductor refrigeration plate is cooling or heating.

[0016] Furthermore: each of the semiconductor refrigeration plates is connected in series with a lamp bead.

[0017] The beneficial effect of adopting this step is: the lamp beads and the semiconductor refrigeration chip are connected in series. Once the semiconductor refrigeration chip is damaged, the lamp beads will not light up, and the semiconductor refrigeration chip can be found to be damaged in time so that it can be replaced and repaired in time.

[0018] Furthermore: a liquid level sensor is also provided in the oil tank body, and the liquid level sensor is electrically connected to the controller.

[0019] The beneficial effect of adopting this step is: since the oil in the oil tank will be consumed, the oil level can be observed by the liquid level sensor and the oil can be replenished in time.

[0020] The beneficial effects of the utility model are:

[0021] 1. This application utilizes a semiconductor refrigeration chip as the temperature control body. Compared with the oil cooler and oil radiator in the prior art, it can first have both cooling and heating functions (the oil radiator can only cool), and does not require additional equipment such as compressors, heat exchangers, and electric heaters, thus consuming less energy and not occupying space.

[0022] 2. In addition, if the oil cooler, oil radiator and other equipment in the prior art are used, additional circulating oil will be needed to increase the amount of oil used, but this is not necessary in the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example

[0037] like Figure 1 and Figure 2 As shown, the utility model provides a temperature-controllable oil tank, comprising:

[0038] The oil tank body 1 has a plurality of slots 11 on the side and bottom of the oil tank body 1. The slots 11 are preferably U-shaped slots rather than semi-enclosed bag-shaped slots. The U-shaped slots are for facilitating heat dissipation from the outer side of the semiconductor cooling plate 2.

[0039] A plurality of semiconductor refrigeration sheets 2 are respectively inserted into the slots 11, the slots 11 are adapted to the semiconductor refrigeration sheets 2, and the semiconductor refrigeration sheets 2 have the ability to cool and heat;

[0040] A controller 3, wherein the controller 3 is electrically connected to a plurality of the semiconductor refrigeration chips 2, wherein the plurality of the semiconductor refrigeration chips 2 are connected in parallel, and the parallel semiconductor refrigeration chips 2 work independently, and will not stop working due to damage to any one of the semiconductor refrigeration chips 2;

[0041] A temperature sensor is provided in the oil tank body 1 and is electrically connected to the controller 3 . The temperature sensor detects the oil temperature in real time, and the controller 3 selects whether to perform heating or cooling according to the actual value of the oil temperature.

[0042] The utility model utilizes a semiconductor refrigeration chip 2 as a cold and hot source, attaches the semiconductor refrigeration chip 2 to the outer wall of the oil tank body 1, and heats or cools by switching the positive and negative poles of the direct current input into the semiconductor refrigeration chip 2, thereby achieving the purpose of controlling the oil temperature in the oil tank body 1.

[0043] Compared with the temperature control equipment such as oil coolers, oil radiators / electric heating rods in the prior art, the semiconductor refrigeration plate 2 is neither in direct contact with the oil nor requires an additional circulating power source, and also has relatively accurate temperature control accuracy.

[0044] On the basis of the above technical solution, a heat-conducting medium is coated between the semiconductor cooling plate 2 and the slot 11 .

[0045] The heat transfer medium is generally heat-conducting silicone oil, which can fill the gap between the semiconductor refrigeration plate 2 and the oil tank body 1, discharge the air, and improve the heat transfer efficiency through the heat transfer medium with a higher thermal conductivity coefficient.

[0046] like Figure 3 As shown, the controller 3 is electrically connected to an AC / DC converter 4, and the positive and negative output ends of the AC / DC converter 4 are both provided with single-pole double-throw relays 5, and the two single-pole double-throw relays 5 are respectively electrically connected to the parallel circuits of several semiconductor refrigeration plates 2.

[0047] The AC / DC converter 4 has the function of converting alternating current into direct current. However, the AC / DC converter only has single-polarity direct current. By controlling the energized state of the two single-pole double-throw relays 5, opposite direct currents are provided respectively to control whether the semiconductor refrigeration plate 2 is cooling or heating.

[0048] Specifically, with Figure 3For example, in the figure, the solid line is one group and the dotted line is another group. The polarity of the parallel circuit connected by the solid line and the dotted line is opposite, which can be switched by the single-pole double-throw relay 5 being attracted or not attracted. Assuming that the solid line is cooling, the dotted line is heating.

[0049] On the basis of the above technical solution, each of the semiconductor refrigeration plates 2 is connected in series with a lamp bead 6 .

[0050] The lamp bead 6 is connected in series with the semiconductor cooling chip 2. If the semiconductor cooling chip 2 is damaged, the lamp bead 6 will not light up, which can promptly detect the damage of the semiconductor cooling chip 2 and enable timely replacement and repair. Even if the lamp bead 6 is broken, it can be replaced in time. In short, whether the lamp bead 6 or the semiconductor cooling chip 2 is broken, the lamp bead 6 can promptly and intuitively reflect the damage in the circuit. The use of the lamp bead 6 can improve maintenance efficiency and equipment reliability at a low cost.

[0051] On the basis of the above technical solution, a liquid level sensor is further provided in the oil tank body 1 , and the liquid level sensor is electrically connected to the controller 3 .

[0052] Since the oil in the oil tank body 1 will be consumed, the oil level can be observed by a liquid level sensor and the oil can be replenished in time.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
