[0043] Reference Figures 1 to 5 The following are several embodiments of the pretreatment equipment for slurry according to the present invention.

[0044] like Figures 1 to 5As shown, the pretreatment equipment for slurry according to this embodiment of the present invention includes a substrate 100, a heat exchange tube 200, an input pipe 400, a first pump body 500, and a heater. The substrate 100 has a receiving cavity 110; an inlet 120 is provided at the top of the substrate 100, and an outlet 130 is provided on the side wall of the substrate 100, with the outlet 130 located at the lower end of the substrate 100; hot water flows into the receiving cavity 110 through the inlet 120 and flows out through the outlet 130; the heat exchange tube 200 is disposed in the receiving cavity 110 and is arranged in a spiral from bottom to top. The structure includes: an input pipe 400 connected to the liquid inlet 230 of the heat exchange tube 200 and located outside the substrate; the heat exchange tube 200 for transporting slurry; a distributor 900 provided inside the heat exchange tube, the distributor 900 having multiple diversion holes 930 arranged along the extension direction of the heat exchange tube, the diversion holes 930 for allowing the transported slurry in the heat exchange tube to pass through; a first pump body 500, disposed on the input pipe 400, for driving the flow of slurry in the input pipe 400; and a heater for heating water, the heater having an outlet end connected to the inlet 120.

[0045] Hot water is added to the inlet 120 through the heater, flows into the receiving cavity 110, and flows out from the outlet 130 at the lower end of the base 100. The slurry flows inside the heat exchange tube 200 driven by the first pump body 500. The heat exchange tube 200 contacts the hot water in the receiving cavity 110, so that the heat of the hot water is transferred to the slurry. The slurry is heated evenly through heat transfer, making it easier for the preheated slurry to enter the firing process, shortening the production cycle and improving the overall production efficiency. The slurry passes through the diversion hole 930 of the distributor 900. The slurry is divided into multiple streams by the distributor 900 and re-merges at the other end of the distributor 900, which improves the problem of uneven dispersion between different raw materials in the slurry. The heat exchange tube 200 is spirally arranged from bottom to top, which can improve the heat exchange effect between hot water and slurry and accelerate the temperature rise of the slurry.

[0046] The inlet 120 is located at the top of the base 100, and the outlet 130 is located at the bottom of the base 100. Hot water enters from top to bottom. Due to gravity, the hot water flows from the top of the base 100 into the receiving cavity 110, making the temperature as uniform as possible along the height direction. This improves the uniformity of water temperature inside the receiving cavity 110 and ensures that the slurry is heated as evenly as possible. By preheating the slurry, the preparation time can be shortened, production efficiency can be improved, and some technical difficulties in the cold slurry processing can be reduced. Generally, hot water refers to water with a temperature higher than room temperature; of course, other high-temperature media can be used instead of hot water during use.

[0047] Generally, the heater is a boiler, which heats the water and then introduces the hot water into the receiving cavity 110. The slurry flows in the heat exchange tube 200, and the temperature of the slurry is increased through heat exchange, avoiding problems such as uneven heating of the slurry caused by direct heating.

[0048] The slurry flowing in the heat exchange tube enters the multiple diversion holes 930 of the diversion device 900 from one end of the diversion device 900. The slurry is divided into multiple streams through the multiple diversion holes 930 and then merges at the other end of the diversion device 900. This breaks the laminar flow of the slurry, allowing the slurry to flow more uniformly and reducing compositional deviation. In addition, the slurry flow may form dead zones within the heat exchange tube. The diversion device 900 can reduce these dead zones, thereby improving the overall flow.

[0049] In some embodiments, multiple distributors 900 are provided, arranged along the extension direction of the heat exchange tube; the diversion holes 930 of two adjacent distributors 900 are staggered in the extension direction of the heat exchange tube. This arrangement causes the slurry to experience an irregular flow path when flowing through the heat exchange tube, increasing flow disturbance and helping to break the original laminar flow, making the slurry more uniformly mixed, and avoiding dead zones or areas with slow flow velocity that may occur in the flow. The staggered arrangement makes the flow path of the slurry in the heat exchange tube more complex. When the slurry passes through different distributors 900, it will be subjected to forces in different directions, generating more mixing effects, which helps to better mix slurries of different components, thereby improving uniformity.

[0050] In some embodiments, such as Figure 5 As shown, the flow divider 900 includes a base 910 and a flow divider plate 920. The base 910 is fitted inside the heat exchange tube, and the flow divider plate 920 and the base 910 are connected by a snap-fit. A notch 921 is provided on the edge of the flow divider plate 920, forming a flow divider hole 930 between the notch 921 and the base 910. The notch 921 on the edge of the flow divider plate 920 can effectively reduce stress concentration and enhance the structural strength of the flow divider plate 920; at the same time, it improves the material utilization rate and avoids additional material loss.

[0051] In some embodiments, such as Figures 1 to 4 As shown, the pretreatment equipment also includes an output pipe 300, which is connected to the liquid outlet 210 of the heat exchange tube 200. The output pipe 300 passes through the top of the substrate 100, and the input pipe 400 passes through the side wall of the substrate 100, with the input pipe 400 located at the lower end of the substrate 100.

[0052] Understandably, the output pipe 300 passes through the top of the base 100, and the input pipe 400 is located at the lower end of the base 100. The output pipe 300 is connected to the liquid outlet 210 of the heat exchange tube 200, and the input pipe 400 is connected to the liquid inlet 230 of the heat exchange tube 200, allowing the slurry to flow from the upper end to the lower end of the base 100. In other words, the slurry and hot water flow in opposite directions to accelerate the heat exchange rate between the slurry and hot water, thereby increasing the slurry's heating rate. The output pipe 300 passes through the top of the base 100, and the input pipe 400 passes through the side wall of the base 100, so that portions of the output pipe 300 and the input pipe 400 are exposed outside the base 100, which facilitates the connection of the output pipe 300 and the input pipe 400 to external equipment. The output pipe 300 and the input pipe 400 are located on the same side of the substrate 100, which facilitates the return of the heated slurry to its original position to await the next process. Of course, in other embodiments, the output pipe 300 and the input pipe 400 are located on different sides of the substrate 100, and this embodiment of the present invention does not impose any particular limitation on this.

[0053] Generally, such as Figure 4 As shown, the output pipe 300, heat exchange pipe 200 and input pipe 400 are integrally formed; the diameter of the heat exchange pipe 200 is 8 to 15 cm to avoid problems such as uneven heating of the slurry inside the heat exchange pipe 200 due to excessive diameter.

[0054] This application introduces hot water into the receiving cavity 110, and through heat exchange between the hot water and the slurry, the temperature of the slurry can be gradually increased. The slurry flows inside the heat exchange tube 200, and the hot water flows inside the receiving cavity 110, which is conducive to the uniform heating of the slurry. Furthermore, after the slurry flows inside the heat exchange tube 200 and is heated by the receiving cavity 110, it can be transported to the next process through the output pipe 300, reducing the amount of slurry remaining inside the substrate 100.

[0055] In some embodiments, such as Figure 1 As shown, the pretreatment equipment also includes a first temperature sensor and a second temperature sensor. The first temperature sensor is located in the output pipe 300, and the second temperature sensor is located in the receiving cavity 110. The first pump body 500 provides power for the conveying of the slurry, so that the slurry flows from the input pipe 400 through the heat exchange pipe 200 and then flows out from the output pipe 300. The first temperature sensor can detect the temperature of the slurry, which is beneficial for better control of the slurry temperature. The second temperature sensor can measure the temperature of the hot water, which can control the temperature of the hot water and avoid the slurry not being able to be heated due to the hot water temperature being too low.

[0056] This embodiment of the invention also includes a control system, which is electrically connected to the first pump body 500 and the first temperature sensor. The control system adjusts the operating parameters of the first pump body 500 based on the temperature feedback from the first temperature sensor, so as to control the temperature of the slurry within a certain range. Generally, a preheating temperature of 70°C is sufficient for the slurry.

[0057] like Figure 1 As shown, an inlet pipe 620 can be installed at the inlet 120, and an outlet pipe 610 can be installed at the outlet 130. The inlet pipe 620 connects to the inlet 120, and the outlet pipe 610 connects to the outlet 130. Hot water is guided to the receiving cavity 110 through the inlet pipe 620 and discharged through the outlet pipe 610 after heat exchange. A second pump body 700 can be installed in the inlet pipe 620 to provide power for the hot water delivery. The control system is electrically connected to the second pump body 700 and a second temperature sensor. Based on the temperature feedback from the second temperature sensor, the operating parameters of the second pump body 700 are adjusted to control the hot water temperature within a certain range for better heat exchange; generally, the hot water temperature is controlled at around 85°C.

[0058] In some embodiments, two second temperature sensors are provided, one of which is located at the upper end of the base 100 and the other at the lower end of the base 100. The temperature of the hot water in the containment cavity 110 can be obtained more accurately by using two second temperature sensors.

[0059] In some embodiments, such as Figure 1 and Figure 4 As shown, the heat exchange tube 200 includes at least two heat exchange sections 220, which are arranged along the height direction of the substrate 100. The slurry flows sequentially through multiple heat exchange sections 220, allowing the slurry to flow along the height direction of the substrate 100. The slurry gradually heats up through heat exchange with the hot water. The heat exchange sections 220 are curved and coiled along the circumferential direction of the substrate 100 to maximize the flow path of the slurry within the receiving cavity 110, further increasing the heat exchange time between the slurry and the hot water, thereby improving the heat exchange effect. Adjacent heat exchange sections 220 are connected by threads.

[0060] In some embodiments, at least one flow divider 900 is provided on the heat exchange section 220, and the flow divider 900 is located at the connection of two adjacent heat exchange sections 220 for easy installation.

[0061] In some embodiments, the angle between the extension direction of the heat exchange section 220 and the height direction of the substrate 100 is greater than 50 degrees, so that the extension direction of the heat exchange tube 200 inside the receiving cavity 110 is as close to the horizontal direction as possible, thereby reducing the influence of gravity on the slurry and making the flow of the slurry in the heat exchange tube 200 smoother.

[0062] In some embodiments, such as Figure 3 As shown, there is a heat insulation gap 111 between the heat exchange section 220 and the inner wall of the receiving cavity 110 to prevent the heat exchange section 220 from directly contacting the inner wall of the substrate 100 and reduce the heat loss of the slurry in the heat exchange section 220.

[0063] In some embodiments, such as Figure 1 As shown, the pretreatment equipment also includes reinforcing ribs 800, which are disposed on the outer wall of the substrate 100. The reinforcing ribs 800 can increase the structural strength of the substrate 100 and improve its resistance to deformation.

[0064] In some embodiments, such as Figure 1 As shown, the reinforcing rib 800 includes multiple first reinforcing ribs 810 and multiple second reinforcing ribs 820. The multiple first reinforcing ribs are arranged along the height direction of the base 100, and the first reinforcing ribs 810 surround the outside of the base 100 along the circumferential direction, which can increase the rigidity of the base 100 in the height direction and improve the load-bearing capacity. The second reinforcing ribs 820 connect two adjacent first reinforcing ribs 810, which can improve the overall rigidity and improve the stress distribution. Along the height direction of the base 100, the second reinforcing ribs 820 are staggered, which improves the structural strength at different positions on the periphery of the base 100.

[0065] In some embodiments, such as Figure 1 As shown, the substrate 100 is cylindrical. The cylindrical structure can minimize the surface area of ​​the substrate 100 while ensuring that the volume of the receiving cavity 110 is large enough, thereby reducing heat loss. The pretreatment equipment also includes a heat insulation layer, which is set on the outside of the substrate 100 and is used to insulate the substrate 100. The heat insulation layer can reduce heat loss and thus achieve the heat insulation effect of the substrate 100.

[0066] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
