[0001] The invention relates to the technical field of heating equipment, in particular to a reagent heating device for a rust-proof cleaning agent research and development experiment. Background Art

[0002] Anti-rust cleaning agent is a decontamination and rust-proof agent for metal products. It can effectively remove surface stains of metal workpieces and has a certain anti-rust effect. In the research and development experiment of anti-rust cleaning agent, a large number of samples are needed for mixing and comparison. During laboratory research and development, sample reagents are stored in test tubes, which will undergo a water bath heating step.

An input control pipe is arranged between the dynamic cylinder and the hot water submersible pump.

[0007] A one-way valve is arranged on the input control tube, and the one-way valve allows the liquid to flow from the hot water submersible pump to the dynamic cylinder in one direction. A fixed square tube is fixedly arranged on the pressure-changing piston, and a split square rod is inserted in the fixed square tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The reagent heating device of the present invention is used for quickly placing a large number of test tubes during laboratory research and development. Through the cooperation of the test tube supporting plate, the liquid spraying cavity path, the hot water submersible pump and other structures, a pressure water column can be sprayed vertically upward from the center of the spherical groove, so that when the test tube is placed, the water column pushes the pressure to play a buffering role, reducing the probability of the bottom of the test tube being broken. There is no need to put it in place gently, and the hands can be directly released after the hole position is aligned. It is faster and safer to use, and the efficiency of experimental research and development is improved. In the subsequent water bath heating, it can promote the flow of water and improve the uniformity of heating.

[0016] By setting up a variable pressure control system, in cooperation with the above-mentioned structures such as the liquid spray chamber, the pressure in the liquid spray chamber can be dynamically changed during the water bath heating process, so that the pressure injection and negative pressure liquid suction at the port of the liquid spray chamber can be switched cyclically. During the pressure injection, the test tube can be lifted up a certain distance, and during the negative pressure liquid suction, the test tube can be quickly sucked down, so that the lifting and shaking of the test tube can be controlled during the water bath heating process to achieve a stirring effect.

[0017] Through the coordination of the fixed square tube, split square rod, toggle plate and control cut-off chamber and other structures, when negative pressure back suction occurs in the dynamic cylinder, the large flow hole and the small flow hole can be controlled in advance to switch, so that the input control tube can carry out flow through the small flow hole, thereby concentrating the negative pressure in the water supply pipe, enhancing the suction pressure of the spray cavity, reducing the weakening of the negative pressure caused by the increase of liquid inlet into the input control tube, and at the same time, the small flow hole can still maintain a certain amount of liquid flow to avoid blockage of the water outlet end of the hot water submersible pump.

[0032] See also Figures 1 to 12 The present invention provides a technical solution: a reagent heating device for a rust-proof cleaning agent research and development experiment, such as Figure 3As shown in the figure, it includes a water bath heating tank 1 and an electric heating plate 2 arranged inside the water bath heating tank 1, the electric heating plate 2 is used to heat the water bath liquid in the water bath heating tank 1, and a support plate 3 is arranged in the water bath heating tank 1, and a test tube hole 4 is opened through the surface of the support plate 3, as shown in the figure. Figure 8 As shown in the figure, a fixed vertical arm 5 and a cross-connecting tube 9 are fixedly provided on the lower surface of the bracket plate 3, and the fixed vertical arm 5 corresponds to the number and position of the test tube hole 4 one by one. A test tube support plate 6 is fixedly provided on the lower end of the fixed vertical arm 5, and a spherical groove 7 is provided on the upper surface of the test tube support plate 6, and the spherical groove 7 is located directly below the corresponding test tube hole 4. A liquid spraying cavity 8 is provided in the fixed vertical arm 5 and the test tube support plate 6, and one end of the liquid spraying cavity 8 is connected to the spherical center of the spherical groove 7, and the opening is vertically upward, and the other end of the liquid spraying cavity 8 is connected to the cross-connecting tube 9, and a hot water submersible pump 10 is provided inside the water bath heating tank 1. The hot water submersible pump 10 is a submersible pump in the prior art that can work in liquids with a maximum temperature of 100°C. The hot water submersible pump 10 extracts liquid from the water bath heating tank 1 and inputs it into the cross-connecting tube 9 under positive pressure.

[0033] A voltage transformer control system is provided below the cross-connection pipe 9, and the voltage transformer control system has a pre-control function. Figure 4 As shown in the figure, the voltage-changing control system includes a dynamic cylinder 901, a voltage-changing piston 902, a constantly connected support ring 903, a water supply connecting pipe 904 and an input control pipe 905. The dynamic cylinder 901 is opened on the side wall surface of the water bath heating tank 1. The voltage-changing piston 902 is sealingly and slidingly arranged inside the dynamic cylinder 901. The constantly connected support ring 903 is fixedly arranged inside the dynamic cylinder 901. The constantly connected support ring 903 limits the voltage-changing piston 902. The water supply connecting pipe 904 is connected between the dynamic cylinder 901 and the cross-connecting pipe 9. The input control pipe 905 is connected between the dynamic cylinder 901 and the hot water submersible pump 10.

[0034] A one-way valve 906 is provided on the input control tube 905, and the one-way valve 906 allows the liquid to flow unidirectionally from the hot water submersible pump 10 to the dynamic cylinder 901. A fixed square tube 907 is fixedly provided on the transformer piston 902, and a split square rod 908 is inserted in the fixed square tube 907. A limiting groove 909 is provided through the surface of the fixed square tube 907, and a limiting slider 910 is fixedly provided on the surface of the split square rod 908. The limiting slider 910 is set in the limiting groove 909 for limiting sliding.

[0035] A grooved rack 911 is provided on the surface of the split square rod 908, and a conversion gear 912 is installed at the upper limit of the fixed square tube 907. The conversion gear 912 and the grooved rack 911 are meshed with each other, and a driving worm 913 is coaxially fixedly installed on one side of the conversion gear 912; the friction force between the variable pressure piston 902 and the inner wall surface of the dynamic cylinder body 901 is greater than the thrust required by the grooved rack 911 when the conversion gear 912 is driven to rotate, thereby ensuring that when the split square rod 908 moves, the conversion gear 912 is driven to rotate first; the friction force between the variable pressure piston 902 and the inner wall surface of the dynamic cylinder body 901 can be changed by adjusting the pressure between the rubber ring of the variable pressure piston 902 and the inner wall surface of the dynamic cylinder body 901.

[0036] The driving worm 913 is externally meshed with a worm wheel 914 , on which a pre-control shaft 915 is coaxially fixedly arranged. The pre-control shaft 915 has an external limiting sleeve provided with a limiting shaft sleeve 916 , which is fixedly mounted to the fixed square tube 907 .

[0037] like Figure 6 As shown in , a control cut-off bin 917 is provided on the input control tube 905, an axial limit arm 918 is fixedly provided on the control cut-off bin 917, an axially movable sleeve 919 is sleeved and installed on the pre-control shaft 915, and the axially limit arms 918 are distributed on both sides of the axially movable sleeve 919 to axially limit the axially movable sleeve 919, and a sleeve limit groove 920 is opened on the pre-control shaft 915 along its axial direction, and a clamping protrusion is fixed on the inner surface of the axially movable sleeve 919, and the above-mentioned clamping protrusion extends into the sleeve limit groove 920, so that when the pre-control shaft 915 rotates, it can drive the axially movable sleeve 919 to rotate.

[0038] like Fig.12 As shown in the figure, a toggle plate 921 is fixedly provided on the outside of the axial rotating sleeve 919, a switching tongue 922 is provided in the control cut-off chamber 917, and a large flow hole 923 and a small beam hole 924 are penetrated by the switching tongue 922, and the diameter of the large flow hole 923 is larger than the diameter of the small beam hole 924.

[0039] A toggle plate matching frame 925 is fixedly provided on the switching tongue 922, and the toggle plate 921 is inserted into the toggle plate matching frame 925. When the toggle plate 921 swings, it can drive the switching tongue 922 to switch and move by cooperating with the toggle plate matching frame 925. A telescopic driver 926 is connected to the end of the split square rod 908, and the split square rod 908 is driven to move along the axial direction of the dynamic cylinder body 901 by the telescopic driver 926. The telescopic driver 926 can be a cylinder or an electric telescopic mechanism.

[0040] A circuit control compartment 101 is fixedly provided on the outside of the water bath heating tank 1 , an inner wall bracket 102 is fixedly provided on the inside of the water bath heating tank 1 , and the bracket plate 3 is limitedly installed above the inner wall bracket 102 .

[0041] In the process of developing anti-rust cleaning agents in the laboratory, it is necessary to heat the reagents in the test tubes in batches in a water bath. The reagent heating device of the present invention can improve the efficiency of research and development. When in use, the water level in the water bath heating tank 1 should be above the test tube support plate 6 by a certain distance, so that after the test tube is inserted, the water level can completely cover the height of the reagent. Figure 3 and Figure 4 As shown in the figure, the hot water submersible pump 10 is running to extract liquid, and the positive pressure is input into the dynamic cylinder 901 through the input control pipe 905. Due to the existence of the constant-through support ring 903, the variable pressure piston 902 does not contact the inner surface of the end of the dynamic cylinder 901, thereby maintaining the connection between the input control pipe 905 and the water supply connecting pipe 904. Therefore, the positive pressure liquid will enter the water supply connecting pipe 904 and be dispersed into the liquid injection cavity 8 through the cross-interconnecting pipe 9. Figure 8 As shown in the figure, a pressure water column is sprayed vertically upward from the center of the spherical groove 7 through the spray cavity 8.

[0042] When inserting the test tube, you can directly let go after aligning the test tube with the test tube hole 4, without gently putting it to the bottom. The test tube falls naturally and is buffered by the pressure water column sprayed vertically upward from the center position of the spherical groove 7; during subsequent water bath heating, it can promote water flow and improve the uniformity of heating.

[0043] When you need to control the test tube to lift, shake and mix, such as Figure 3 and Figure 4 As shown in , the telescopic drive 926 controls the split square rod 908 to telescope and reciprocate, and the stroke is sufficient; Figure 4 As shown in the figure, when the telescopic drive 926 contracts, the split square rod 908 moves to the left. Since the friction between the variable pressure piston 902 and the dynamic cylinder 901 is greater, the split square rod 908 first moves relative to the fixed square tube 907. The split square rod 908 drives the conversion gear 912 to rotate through the groove rack 911, causing the driving worm 913 to rotate until the limit slider 910 moves to the left side of the limit slide groove 909 and is limited.

[0044] When the driving worm 913 rotates, the worm wheel 914 is driven to rotate, and the worm wheel 914 drives the pre-control shaft 915 to rotate. Figure 6 As shown in FIG. , the pre-control shaft 915 drives the shaft-moving sleeve 919 to rotate, so that the toggle plate 921 swings, as shown in FIG. Fig.12As shown in the figure, when the toggle plate 921 swings clockwise, it drives the switching tongue 922 to move, so that the beam hole 924 moves to the axial position of the input control tube 905, and is connected with the input control tube 905 through the beam hole 924, thereby making the internal beam of the input control tube 905.

[0045] like Figure 4 As shown in the figure, when the limit slider 910 moves to the left side of the limit slot 909 and is limited, as the split square rod 908 continues to move left, the split square rod 908 will drive the transformer piston 902 to move left, so that negative pressure suction is generated inside the dynamic cylinder 901. Since the interior of the input control tube 905 is beamed by the beam hole 924, the negative pressure is concentrated into the water supply connecting tube 904, causing negative pressure absorption in the spray cavity 8.

[0046] When the telescopic driver 926 is extended, the split square rod 908 moves to the right. Similarly, the conversion gear 912 is first driven to reverse, so that the switching tongue 922 is reset. At this time, the large flow hole 923 is connected to the input control tube 905, so that the input control tube 905 releases the beam flow to avoid affecting the flow input of the hot water submersible pump 10. After the split square rod 908 is pushed to the bottom, the variable pressure piston 902 is pushed to the right, so that the dynamic cylinder 901 assists in increasing the input flow into the water supply connecting pipe 904, and then the liquid spraying cavity 8 is pressurized and sprayed, and the test tube is lifted by one end. In the next cycle, the negative pressure absorption of the liquid spraying cavity 8 causes the test tube to drop rapidly, and the test tube is lifted and shaken through the cycle to achieve a stirring effect.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
