Description

Technical Field

[0001] This utility model relates to the technical field of pigment cooling equipment, and in particular to a rapid cooling equipment for the production of iron oxide pigments. Background Technology

[0002] To address the specific needs of iron oxide pigment production, developing a dedicated cooling device that can achieve rapid and uniform cooling without affecting product quality and is compatible with continuous production is of great significance for improving the production efficiency of iron oxide pigments, reducing energy consumption, and ensuring product stability.

[0003] Existing cooling equipment often uses threaded unions to lock the connection between the inlet and outlet water pipes and the cooling water circulation pipes. However, most of these threaded unions or pipe assemblies lack a mechanism that allows for direct, real-time tightening and loosening without the need for an external wrench. This means that when fixing the pipe assemblies and cooling water circulation pipes, an external wrench must be used, which is cumbersome and inconvenient. Furthermore, it prevents the timely and efficient tightening of the threaded union to lock and seal the joint and eliminate leaks when leaks occur at the connection between the pipe assemblies and cooling water circulation pipes. Utility Model Content

[0004] In view of this, the present invention provides a rapid cooling device for the production of iron oxide pigments, in order to solve the problem of the lack of a mechanism that can directly drive the threaded joint to tighten or loosen in real time without the need for an external wrench.

[0005] The technical solution proposed by this utility model is as follows: a rapid cooling device for the production of iron oxide pigment, specifically including a conduit assembly; the conduit assembly consists of a vertical main pipe, a row of short connecting pipes welded to one side of the vertical main pipe, and a horizontal conduit welded to the middle part of the other side of the vertical main pipe; two L-shaped retaining rods are symmetrically welded on the vertical main pipe, and a cooling circulation pipe is fixedly installed between the tail ends of the two L-shaped retaining rods, with a threaded ring formed at the head end of the cooling circulation pipe; the vertical main pipe is provided with a threaded part that rotates and slides with it. The sleeve consists of a threaded sleeve and a threaded ring, which are screwed together. When the threaded sleeve is tightened, the threaded ring and the mating ring abut against each other, and a rubber washer is squeezed and clamped between the threaded ring and the mating ring. The tail end of the outer periphery of the threaded sleeve is rotatably connected to multiple levers. A slip ring is slidably fitted on the transverse guide tube, and a connecting rod is rotatably connected between the slip ring and the levers. A positioning ring is slidably fitted on the outer periphery of the threaded sleeve. Two force transmission shafts are symmetrically fixed between the positioning ring and the slip ring. A positioning bolt is screwed through the thread on the peripheral wall of the positioning ring, and the head end of the positioning bolt is pressed against the top of the threaded sleeve.

[0006] Furthermore, it also includes a cooling tank, inside which a pigment container is inserted. Multiple rows of load-bearing connecting plates are fixedly connected to the cooling tank. A cover ring is formed at the top of the cooling tank, and the inner circumference of the cover ring is welded and fixed to the outer circumference of the top part of the pigment container.

[0007] Furthermore, an annular flow channel for circulating cooling water is formed between the cooling tank and the pigment container, and a horizontally placed conduit is welded and fixed to the peripheral wall of the cooling tank and communicates with the annular flow channel.

[0008] Furthermore, a feed pipe and a discharge pipe are welded to the center of the two cover plates at the top and bottom of the pigment container, respectively, and a valve is installed on the discharge pipe.

[0009] Furthermore, the unloading pipe is welded through to the bottom plate of the cooling tank.

[0010] Furthermore, the conduit assembly and the cooling circulation pipe are symmetrically arranged in two places, and the tail ends of the two cooling circulation pipes are respectively connected to the inlet pipe and outlet pipe of the external cooling water circulation system.

[0011] The rapid cooling device for iron oxide pigment production provided by this utility model has the following beneficial effects:

[0012] 1. When multiple levers are driven to rotate to the unfolded state perpendicular to the threaded sleeve, they can be used as a torque drive tool for the threaded sleeve to directly tighten or loosen it. This eliminates the need for an external wrench to tighten or loosen the threaded sleeve, which is troublesome for assembling or disassembling cooling circulation pipes and horizontal conduits. The operation is simple and convenient. Furthermore, when a leak is found due to a loose or incomplete connection between the mating ring and the threaded ring, the threaded sleeve can be tightened directly to squeeze and seal the connection, thus eliminating the leakage defect in time.

[0013] Second, when multiple handles are driven to swing to the retracted state, they are parallel and close to the threaded sleeve. This reduces the space occupied by multiple handles when they are not in use, and avoids the multiple handles remaining in the extended and protruding support state when not in use, which could easily cause collision injuries to the worker's limbs.

[0033] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0034] This embodiment includes a cooling tank 1, inside which a pigment container 2 is inserted. Multiple rows of load-bearing connecting plates 203 are fixedly connected around the cooling tank 1. A cover ring 101 is formed at the top of the cooling tank 1, and the inner circumference of the cover ring 101 is welded and fixed to the outer circumference of the top part of the pigment container 2. An annular flow channel for circulating cooling water is formed between the cooling tank 1 and the pigment container 2. A horizontally placed conduit 302 is welded and fixed to the peripheral wall of the cooling tank 1 and communicates with the annular flow channel.

[0035] Preferably, a feed pipe 201 and a discharge pipe 202 are welded to the center of the top and bottom covers of the pigment container 2, respectively, and a valve is provided on the discharge pipe 202.

[0036] Preferably, the unloading pipe 202 is welded through to the bottom plate of the cooling tank 1.

[0037] Preferably, the conduit assembly 3 and the cooling circulation pipe 5 are symmetrically arranged in two places, and the tail ends of the two cooling circulation pipes 5 are respectively connected to the inlet pipe and outlet pipe of the external cooling water circulation system.

[0038] Preferably, the bottom of the cooling tank 1 is welded with three vertical support columns 102; the end of the threaded sleeve 4 is internally formed with a force transmission ring 402, and the mating ring 3021 abuts against the force transmission ring 402.

[0039] The following provides a detailed explanation of the specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in implementing this technical solution:

[0040] Pigment container 2 is used to hold iron oxide pigment that is waiting to be cooled. The iron oxide pigment is fed into pigment container 2 through feed pipe 201. After cooling treatment, the iron oxide pigment is fed into the next process through discharge pipe 202 and external conveying pipe connected to discharge pipe 202 for subsequent processing or to storage container for temporary storage.

[0041] Two conduit assemblies 3 are provided. One conduit is used to input unused low-temperature cooling water into the annular flow channel to cool the iron oxide pigment in the pigment container 2. The other conduit is used to collect and transport the used cooling water with a certain temperature to the cooling water circulation system for cooling and recycling. A water path for cooling water circulation is established between the cooling water circulation system, the two conduit assemblies 3, the two cooling circulation pipes 5, and the annular flow channel. The cooling water continuously circulates in this water path. When the low-temperature unused cooling water flows into the annular flow channel, it is diverted by the arc guiding effect of the peripheral wall of the pigment container 2 and flows around the two halves of the peripheral wall of the pigment container 2. When the cooling water flows around the peripheral wall of the pigment container 2, it can use the peripheral wall to conduct a more sufficient heat exchange with the high-temperature iron oxide pigment inside the pigment container 2 and absorb the heat contained in the high-temperature iron oxide pigment more fully, thereby reducing the temperature of the iron oxide pigment more quickly.

[0042] The cooling circulation pipe 5 and the horizontal conduit 302 are locked together using a threaded sleeve 4. Multiple levers 401, multiple connecting rods 4041, and a slip ring 404 are connected to form a crank-slider mechanism. Through this mechanism, sliding the slip ring 404 along the horizontal conduit 302 towards or away from the cooling tank 1 drives the multiple levers 401 to swing and extend. When the multiple levers 401 are driven to swing to an extended state perpendicular to the threaded sleeve 4, they can act as a torque drive for the threaded sleeve 4, directly tightening or loosening it. This eliminates the need for an external wrench to tighten or loosen the threaded sleeve 4, thus improving the cooling circulation pipe... The assembly and disassembly of the horizontal conduit 302 is simple and convenient, eliminating the hassle of assembly and disassembly. Furthermore, by using a rotary drive tool, when a leak is found due to a loose or incomplete connection between the mating ring 3021 and the threaded ring 501, the threaded sleeve 4 can be tightened directly to seal the connection and promptly eliminate the leakage defect. When the multiple levers 401 are driven to swing to the retracted state, they are parallel and close to the threaded sleeve 4. This reduces the space occupied by the multiple levers 401 in the idle state and avoids the multiple levers 401 remaining in the extended and protruding support state when idle, which could easily cause collision injuries to the workers' limbs.

[0043] The positioning bolt 4031 can tighten and fix the positioning ring 403 and the slip ring 404, keeping the handlebar 401 in the extended or retracted state.

[0044] The mating gap between the mating ring 3021 and the threaded ring 501 is indirectly sealed by the threaded sleeve 4 through the rubber gasket 6 by the locking and compressing force.
