Description

Technical Field

[0001] This utility model relates to the field of silica slurry technology, and in particular to a silica slurry cooling device. Background Technology

[0002] Silica (precipitated silica) is a high-performance filler widely used in industries such as rubber, plastics, coatings, and cosmetics. During production, silica is typically present in slurry form and requires cooling to control its temperature and viscosity, ensuring stability for subsequent processing (such as drying and granulation).

[0003] Existing technologies employ open or closed cooling tanks, relying on natural convection and refrigerant within external coils to remove heat. However, due to the high viscosity and agglomeration properties of silica slurry, static cooling leads to stratified deposition of the slurry, forming dense agglomerates at the bottom. This results in uneven cooling, low heat exchange efficiency, and other problems, affecting product quality and production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that static cooling leads to slurry layering and deposition, forming dense agglomerates at the bottom, resulting in uneven cooling and low heat exchange efficiency. Therefore, a precipitated silica slurry cooling device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precipitated silica slurry cooling device includes a cooling chamber, a disassembly base is provided inside the cooling chamber, a coil for storing refrigerant is installed on the disassembly base, a stirring chamber is provided inside the cooling chamber, and the coil is in contact with the outer wall of the stirring chamber. A rectangular rotating rod is provided inside the stirring chamber, and multiple stirring paddles are fixedly connected to the rectangular rotating rod.

[0007] Also includes:

[0008] A drive assembly is disposed on the mixing chamber and is used to drive the rectangular rotating rod to rotate and stir the silica.

[0009] Preferably, the drive assembly includes a mounting groove formed on the vertical outer wall of the mixing chamber, a cross shaft rotatably connected to the vertical inner wall of the mixing chamber, a motor for driving the cross shaft to rotate fixed in the mounting groove, connecting posts horizontally inserted at opposite ends of the two cross shafts, rectangular blocks fixed at opposite ends of the two connecting posts, a side groove formed on the side wall of the rectangular block opposite the rectangular rotating rod, a spring fixedly connected in the side groove, and the spring and the rectangular rotating rod being fixedly connected.

[0010] Preferably, the rectangular rotating rod and the side groove are horizontally slidably connected, and the connecting column has a cross groove on its side wall relative to the cross shaft to facilitate horizontal insertion of the cross shaft.

[0011] Preferably, an inlet pipe is fixedly and continuously installed on the coil, and a sealing plug is installed on the inlet pipe.

[0012] Preferably, the disassembly base and the cooling chamber are threadedly connected by the same bolt, the top of the mixing chamber is provided with a sealing cover, a support platform is fixed inside the cooling chamber, and the mixing chamber is located on top of the support platform.

[0013] Preferably, the bottom of the cooling chamber is fixed with a base plate, and four support legs are fixedly connected to the bottom of the base plate.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] This invention, through the design of a drive structure, springs, and a cross shaft, allows the circulating coolant in the coil to efficiently absorb heat through the closely contacting walls of the mixing chamber after the silica slurry is injected. The motor drives multiple sets of stirring paddles through the cross shaft and rectangular rotor, and the rectangular rotor and stirring paddles are detachable, effectively eliminating local temperature differences in the slurry and preventing silica particle agglomeration. This dual mechanism ensures the stability of the cooling rate and avoids uneven cooling caused by slurry agglomeration, providing a consistent slurry foundation for subsequent processing steps.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A precipitated silica slurry cooling device includes a cooling chamber 1, which is made of a robust and durable material with good thermal insulation properties, effectively reducing the impact of the external environment on the internal cooling process. A disassembly base 2 is installed inside the cooling chamber 1, on which a coil 22 for storing coolant is mounted. The coil 22 is made of a metal with excellent thermal conductivity and fits tightly against the outer wall of a mixing chamber 4 to maximize heat exchange efficiency. A mixing chamber 4 is located inside the cooling chamber 1. The mixing chamber 4 is made of corrosion-resistant material and has a smooth internal design to reduce slurry residue. The coil 22 is in contact with the outer wall of the mixing chamber 4, and the coolant in the coil 22 carries away the heat from the slurry in the mixing chamber 4, thus achieving cooling. A rectangular rotating rod 5 is installed inside the mixing chamber 4, and multiple stirring paddles 6 are fixedly connected to the rectangular rotating rod 5. The multiple stirring paddles 6 are regularly distributed to ensure thorough mixing of the slurry and avoid localized overheating or uneven cooling.

[0024] Also includes:

[0025] The drive assembly is located on the mixing chamber 4 and is used to drive the rectangular rotating rod 5 to rotate and stir the silica.

[0026] The drive assembly includes a mounting groove 41 on the vertical outer wall of the mixing chamber 4, and a cross shaft 43 rotatably connected to the vertical inner wall of the mixing chamber 4. A motor 42 for driving the cross shaft 43 is fixed within the mounting groove 41. Connecting posts 44 are horizontally inserted into the opposite ends of the two cross shafts 43, ensuring smooth power transmission and reducing vibration. Rectangular blocks 45 are fixed to the opposite ends of the two connecting posts 44. Side grooves 46 are formed on the side walls of the rectangular blocks 45 relative to the rectangular rotating rod 5. Springs 47 are fixedly connected within the side grooves 46, providing elastic force to facilitate quick insertion of the connecting posts 44 onto the cross shafts 43 by the operator. The springs 47 and the rectangular rotating rod 5 are fixedly connected.

[0027] The rectangular rotating rod 5 and the side groove 46 are horizontally slidably connected. The connecting post 44 has a cross groove 48 on its side wall relative to the cross shaft 43 to facilitate horizontal insertion of the cross shaft 43. The cross groove 48 is designed to facilitate quick disassembly and assembly, reducing maintenance difficulty.

[0028] A liquid inlet pipe 23 is fixedly installed on the coil 22, and a sealing plug 24 is installed on the liquid inlet pipe 23. The liquid inlet pipe 23 facilitates the rapid injection and circulation of coolant, and the sealing plug 24 ensures that the coolant does not leak, avoiding contamination or waste.

[0029] The mounting base 2 and the cooling chamber 1 are threaded together by the same bolt 21, allowing for quick connection and disassembly of the cooling chamber 1, facilitating maintenance and cleaning of the coil 22. A sealing cover 7 is installed on the top of the mixing chamber 4 to ensure its airtightness and prevent slurry evaporation or contamination during cooling. A support platform 3 is fixed inside the cooling chamber 1, and the mixing chamber 4 is positioned on top of the support platform 3. A protrusion is provided on the front of the support platform 3 to prevent the mixing chamber 4 from falling off during operation.

[0030] The bottom of the cooling chamber 1 is fixed with a base plate 8, and four support legs 9 are fixedly connected to the bottom of the base plate 8. The base plate 8 enhances the overall structural stability, and the support legs 9 are made of non-slip and wear-resistant material to ensure that the device does not shift during operation.

[0031] The functional principle of this utility model can be explained through the following operation methods:

[0032] Installation Preparation: Secure the mounting bracket 2 to the cooling chamber 1 using bolts 21. After securing, place the mixing chamber 4 on top of the support platform 3, ensuring that the coil 22 is tightly attached to the outer wall of the mixing chamber 4. After injecting refrigerant into the coil 22 through the inlet pipe 23, seal it with the sealing plug 24. Place the mixing chamber 4 on the support platform 3 and cover the top with a sealing cap 7 to form a sealed space.

[0033] Slurry injection: Open the sealing cover 7, pour the precipitated silica slurry to be cooled into the mixing chamber 4, and reseal it to prevent heat loss.

[0034] Start-up drive: Turn on motor 42, which drives cross shaft 43 to rotate, transmitting power to rectangular block 45 through connecting column 44. Rectangular block 45 drives rectangular rotating rod 5 to rotate, thereby driving stirring paddle 6 to rotate at a constant speed.

[0035] Cooling process: The coolant circulates within coil 22, absorbing heat from the slurry. The rotation of the agitator 6 ensures that the slurry makes uniform contact with the cooling surface of coil 22, improving heat exchange efficiency.

[0036] When the rectangular rotating rod 5 needs to be removed for cleaning and maintenance, the two rectangular blocks 45 are moved horizontally relative to each other, the spring 47 is compressed, and the connecting column 44 is moved away from the cross shaft 43. Thus, the rectangular rotating rod 5 and the stirring paddle 6 can be removed together for cleaning and maintenance, preventing bacteria from growing on the rectangular rotating rod 5 and the stirring paddle 6 and affecting the subsequent stirring effect.

[0037] The entire process utilizes a modular design to achieve efficient cooling and convenient maintenance, making it suitable for continuous production.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
