Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a low-energy consumption pulp storage tank. Background Art

[0002] The slurry storage tank provides a temporary storage space for calcium carbonate slurry. In the calcium carbonate production process, due to the mismatch between the continuity of production and the intermittent nature of downstream processes, the slurry storage tank can store a certain amount of slurry to ensure that the upstream production progress will not be affected by the temporary stagnation of downstream processes. For example, when subsequent filtration, drying and other processes fail or require maintenance, the slurry in the slurry storage tank can continue to provide raw materials for other production lines or emergency orders to ensure uninterrupted production.

[0003] In the prior art, a temperature detection device is required to be installed in the slurry storage tank, and manual observation of the heating temperature and the degree of mixing is required, and the heating device and the stirring device are started to heat and stir the calcium carbonate solution in the slurry storage tank. Manual observation has a lag, and heating and stirring are often not started or stopped at the most appropriate time. Precipitation may occur, or the temperature may be too high but the stirring and heating are not stopped in time, resulting in excessive consumption of energy. Heating is started only when more lumps have appeared or the temperature has dropped a lot, and more energy is needed to increase the temperature and stir evenly. Utility Model Content

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-7 , the present utility model provides a technical solution:

[0031] Refer to Figures 1-7As shown in the figure, a low - energy - consuming pulp storage tank includes a pulp storage tank body 1, a base 2, a storage battery 3, a heating wire 5, and a servo motor 10. The storage battery 3 is arranged on one side of the pulp storage tank body 1. The base 2 is fixedly installed at the bottom of the pulp storage tank body 1. The heating wire 5 is arranged on the pulp storage tank body 1. The servo motor 10 is arranged on the base 2;

[0032] Inside the pulp storage tank body 1, there is a circuit mechanism 4 connected to the storage battery 3. A heating mechanism 7 is arranged on the pulp storage tank body 1. The circuit mechanism 4 and the heating mechanism 7 cooperate with each other to control the start of the servo motor 10. Inside the base 2, there is a power - off mechanism 8. The power - off mechanism 8 and the circuit mechanism 4 cooperate with each other to separately control the turning on of the heating wire 5.

[0033] The nickel - titanium alloy of the shape - memory alloy spring 702 has undergone shape - memory treatment, and its transformation temperature is around 60 degrees or below. Then, when the temperature exceeds 60 degrees, the shape - memory effect will be triggered, and the shape - memory alloy spring 702 will return to the pre - set shape, that is, the shape - memory alloy spring 702 will extend. This will cause the third copper sheet 703 to separate from the two first copper sheets 406, playing a role in blocking the current, so that the current cannot pass through the circuit mechanism 4 to start the servo motor 10 and the heating wire 5. The servo motor 10 cannot drive the rotating rod 6 and the stirring blade 9 to stir, and the heating wire 5 stops heating the calcium carbonate solution inside the pulp storage tank body 1. The above makes it stop heating if the temperature inside the pulp storage tank body 1 exceeds 60 degrees. When the temperature inside the pulp storage tank body 1 drops to a certain temperature, it will be reheated again, keeping the pulp storage tank body 1 between 40°C and 60°C. The above heating of the calcium carbonate solution inside the pulp storage tank body 1 has real - time performance, preventing possible precipitation or the situation where the temperature is already too high but the stirring and heating are not stopped in time, resulting in excessive energy consumption.

[0034] At the same time, the temperature of the pulp storage tank body 1 is usually between 40°C and 60°C, which is more suitable and can better achieve the effect of low energy consumption.

[0035] On the one hand, this temperature range can effectively prevent excessive evaporation of water in the pulp, reduce the change in pulp concentration caused by water loss and the increase in subsequent processing difficulty. At the same time, it can also avoid excessive energy consumption caused by too high temperature.

[0036] On the other hand, within this temperature range, the calcium carbonate pulp has good stability, is not prone to precipitation, caking and other phenomena, which is beneficial to maintaining the uniformity and fluidity of the pulp and providing good conditions for subsequent production processes.

[0037] If the temperature in the slurry storage tank body 1 is appropriate and only stirring is required, pull the third copper sheet 703 downward and rotate it by 90 degrees, place the grip 801 on the bottom of the convex block 805, compress the return spring 802, and the fourth copper sheet 804 moves away from the second copper sheet 407. The heating wire 5 stops heating the calcium carbonate in the slurry storage tank body 1, which can play a role in saving energy.

[0038] Refer to Figure 2 , it also includes a circuit mechanism 4. The circuit mechanism 4 includes a first circuit 401, the first circuit 401 is connected to the positive pole of the storage battery 3. A second circuit 402, a third circuit 403, and a sixth circuit 408 are fixedly installed on the servo motor 10. A fifth circuit 405 is fixedly installed on the positive pole of the storage battery 3. A fourth circuit 404 is connected to the heating wire 5.

[0039] Specific circuits are connected to specific components. For example, the first circuit 401 is connected to the positive pole of the storage battery 3, which clarifies the input path of the current and ensures the stability and reliability of the power supply.

[0040] Refer to Figures 2-3 , the other end of the first circuit 401 is connected to a first copper sheet 406. Another first copper sheet 406 is fixedly installed at the other end of the second circuit 402 away from the servo motor 10. Second copper sheets 407 are installed at the end of the fourth circuit 404 away from the heating wire 5 and the end of the sixth circuit 408 away from the servo motor 10.

[0041] The first circuit 401 and the second circuit 402 are connected by copper sheets. Copper has good electrical conductivity, which can ensure the stable transmission of current at the connection point. Compared with other materials, copper has a smaller resistance, can reduce energy loss, and improve the transmission efficiency of the circuit.

[0042] Refer to Figure 4 , it also includes a heating mechanism 7. The heating mechanism 7 includes a copper block 701. The copper block 701 is installed at the bottom of the slurry storage tank body 1. A shape memory alloy spring 702 is fixedly installed at the bottom of the copper block 701. A third copper sheet 703 adapted to the first copper sheet 406 is fixedly installed at the bottom end of the shape memory alloy spring 702.

[0043] The presence of the shape memory alloy spring 702 can automatically adjust its length according to the temperature change, thereby controlling the contact state between the third copper sheet 703 and the second copper sheet 407. When the temperature is low, the shape memory alloy spring 702 contracts, making the third copper sheet 703 in good contact with the second copper sheet 407 and turning on the heating circuit. When the temperature reaches the set value, the shape memory alloy spring 702 elongates, disconnects the third copper sheet 703 from the second copper sheet 407, and stops heating. This automatic control method can accurately control the temperature in the tank and avoid energy waste caused by overheating.

[0044] Refer to Figures 5-6 , it further includes a power-off mechanism 8. The power-off mechanism 8 includes a grip 801. A connecting rod 803 is fixedly installed at the top of the grip 801. A fourth copper sheet 804 is fixedly installed at the telescopic end of the connecting rod 803. A return spring 802 is arranged between the fourth copper sheet 804 and the base 2. A convex block 805 is fixedly installed at the bottom of the base 2.

[0045] The top end of the return spring 802 abuts against the fourth copper sheet 804, and the bottom end of the return spring 802 is fixedly connected to the inner bottom wall of the base 2.

[0046] The arrangement of the return spring 802 can conveniently restore the power-off mechanism 8 to the initial state after the emergency is lifted. When the grip 801 is released, the elastic force of the return spring 802 causes the connecting rod 803 and the fourth copper sheet 804 to automatically descend and reconnect to the circuit, restoring the normal power supply of the slurry storage tank. This design improves the reliability and operability of the power-off mechanism 8.

[0047] Refer to Figures 5-6 , a copper block 701 is fixed at the bottom of the base 2. The copper block 701 extends a heat-conducting part. A shape memory alloy spring 702 is wound around the outer wall of the heat-conducting part of the copper block 701. A rubber layer is integrally formed on the outer wall of the grip 801.

[0048] It should be noted that the copper block 701 is fixedly installed at the bottom of the slurry storage tank body 1. The top of the copper block 701 extends into the slurry storage tank body 1. The shape memory alloy spring 702 is wound around the outer wall of the heat-conducting part of the copper block 701. When the calcium carbonate solution passes through the copper block 701, the temperature can be quickly transferred to the shape memory alloy spring 702. When the shape memory alloy spring 702 contacts the copper block 701, the part of the shape memory alloy spring 702 in contact with the copper block 701 can better return to the pre-set shape, and the shape memory alloy spring 702 extends. This extended distance causes the third copper sheet 703 to separate from the abutment with the first copper sheet 406.

[0049] Rubber is a good insulating material. In the electrical environment of the slurry storage tank, the rubber layer can provide additional insulation protection for the operator.

[0050] Refer to Figure 2 , the driving end of the servo motor 10 is connected with a rotating rod 6. A stirring blade 9 is fixedly installed on the outer wall of the rotating rod 6.

[0051] The servo motor 10 drives the rotating rod 6 to rotate, driving the stirring blade 9 to stir the slurry in the slurry storage tank. The stirring effect can make the solid particles in the slurry evenly distributed, avoiding the occurrence of particle precipitation and stratification phenomena. This can ensure that the composition of the slurry output from the slurry storage tank is consistent and improve the stability of product quality.

[0052] Refer to Figures 2-3 , on the outer walls of the first circuit 401, the second circuit 402, the third circuit 403, the fourth circuit 404, the fifth circuit 405, and the sixth circuit 408, wire pipes 11 are provided, and the wire pipes 11 are installed on the inner wall of the base 2.

[0053] The wire pipes 11 can play a good protective role for the first circuit 401, the second circuit 402, the third circuit 403, the fourth circuit 404, the fifth circuit 405, and the sixth circuit 408. It can prevent the circuits from being physically damaged externally. During the use of the slurry storage tank body 1, it may be affected by various external forces. The wire pipes 11 can provide a strong layer of protection for the circuits and extend the service life of the circuits. The presence of the wire pipes 11 makes the installation of the circuits more convenient and fast.

[0054] Working principle: The shape memory alloy spring 702, this nickel-titanium alloy, has undergone shape memory treatment, and the transformation temperature is around 60 degrees or below. Then when the temperature exceeds 60 degrees, the shape memory effect will be triggered, and the shape memory alloy spring 702 will return to the pre-set shape, that is, the shape memory alloy spring 702 will extend. This will cause the third copper sheet 703 to separate from the two first copper sheets 406, playing a role in blocking the current, so that the current cannot pass through the circuit mechanism 4 to start the servo motor 10 and the heating wire 5. The servo motor 10 cannot drive the rotating rod 6 and the stirring blade 9 to stir, and the heating wire 5 stops heating the calcium carbonate solution inside the slurry storage tank body 1. The above makes it so that if the temperature inside the slurry storage tank body 1 exceeds sixty degrees, the heating will stop, and when the temperature inside the slurry storage tank body 1 drops to a certain temperature, it will be reheated again, keeping the slurry storage tank body 1 between 40°C and 60°C. The above heating of the calcium carbonate solution inside the slurry storage tank body 1 is real-time, preventing possible precipitation or the situation where the temperature is already too high but the stirring and heating are not stopped in time, resulting in excessive energy consumption.

[0055] At the same time, it is more appropriate for the temperature of the slurry storage tank body 1 to be usually between 40°C and 60°C, which can better achieve the effect of low energy consumption.

[0056] On the one hand, this temperature range can effectively prevent the excessive evaporation of water in the slurry, reduce the change in the slurry concentration caused by water loss and the increase in subsequent processing difficulty. At the same time, it can also avoid excessive energy consumption caused by too high a temperature.

[0057] On the other hand, within this temperature range, the calcium carbonate slurry has good stability and is not prone to phenomena such as precipitation and caking, which is beneficial to maintaining the uniformity and fluidity of the slurry and providing good conditions for subsequent production processes.

[0058] If the temperature inside the slurry storage tank body 1 is appropriate and only stirring is required, pull the third copper sheet 703 downward, rotate it by 90 degrees, place the grip 801 on the bottom of the convex block 805, compress the return spring 802, and the fourth copper sheet 804 moves away from the second copper sheet 407. The heating wire 5 stops heating the calcium carbonate inside the slurry storage tank body 1, which can play a role in saving energy.
