Description

Technical Field

[0001] The utility model relates to a flame retardant cooling device, belonging to the field of flame retardant production. Background Art

[0002] During the production of flame retardants, a large amount of heat will be released, and the temperatures of various reactants are relatively high, so cooling is required. The temperature of the newly produced flame retardant is also relatively high, and it needs to be cooled before packaging and shipping. The current cooling method is generally stirring cooling, which is relatively slow. In order to improve the cooling efficiency, the Chinese patent specification with the application number 201620025446.4 discloses a cooling and stirring device for flame retardant production, including a shell. A main rotating shaft is arranged in the shell, and the main rotating shaft is connected to a motor located above the shell. Spiral blades are arranged on the main rotating shaft, and a sleeve is sleeved outside the spiral blades. The bottom of the sleeve is fixedly arranged at the bottom of the shell, and a plurality of feed holes are opened on the side wall of the bottom of the sleeve. A plurality of connecting rods are arranged at the top of the main rotating shaft, and the lower side of the other end of the connecting rod is connected to a secondary rotating shaft. A plurality of first stirring rods are evenly arranged on the secondary rotating shaft, and a plurality of second stirring rods are evenly arranged on the inner side wall of the shell. The first stirring rods and the second stirring rods are arranged alternately. A cooling shell is sleeved outside the shell, and a cooling system is arranged outside the cooling shell. The cooling system includes a water pump and a cooling device. The water pump is communicated with the cooling device by a water pipe, the other end of the water pump is connected to the water inlet of the cooling shell through a water pipe, and the other end of the cooling device is connected to the water outlet of the cooling shell through a water pipe. A temperature sensor is arranged at the top of the shell, and the temperature sensor, the water pump, the cooling device and the motor are all electrically connected to a control device. The outside of the cooling shell of this patent has a water cooling system, which can cool efficiently. However, because only the outer wall is cooled, the contact surface with the material is small, which affects the cooling effect. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a flame retardant cooling device to solve the problem in the prior art that the contact surface between the cooling device and the material is small, which affects the cooling effect.

[0004] To solve the above problems, the flame retardant cooling device involved in the utility model adopts the following technical scheme: A flame retardant cooling device includes a horizontal cylinder body, the cylinder body has a feeding and discharging port, and a sealing door is sealed on the feeding and discharging port. Two sealing caps are arranged at both ends of the cylinder body, and the sealing caps are rotationally matched with the cylinder body. A spiral cooling water pipe is arranged in the cylinder body, and both ends of the spiral cooling water pipe extend out of the two sealing caps. A scraping plate is arranged in the gap between the spiral cooling water pipe and the cylinder body. The scraping plate is fixed on the inner wall of the cylinder body and extends from one end of the cylinder body to the other end, and the cylinder body is driven to rotate by a power device.

[0005] The described cylinder body is in transmission connection with the power device through an annular friction surface provided on its outer peripheral surface.

[0006] The diameter of the described friction surface is larger than the outer diameter of the cylinder body.

[0007] Annular retaining edges are convexly provided at both ends of the described friction surface.

[0008] Both ends of the described spiral cooling water pipe have straight pipe heads that extend from the peripheral wall of the sealing cap, and the two straight pipe heads are screwed onto both ends of the spiral cooling water pipe.

[0009] A central shaft is penetrated through the center of the described spiral cooling water pipe, and both ends of the central shaft penetrate through the two sealing caps and are fixed to the two sealing caps.

[0010] The described spiral cooling water pipe is fixed to the central shaft.

[0011] A cooling water channel is opened in the center of the described central shaft.

[0012] The described sealing cap is sleeved on the end head of the cylinder body.

[0013] The described feeding and discharging port is a long-shaped feeding and discharging port, and a sealing door is provided on the feeding and discharging port.

[0014] The cylinder body of the present utility model is horizontal. When the cylinder body drives the scraper to rotate, it will drive the flame retardant between the spiral cooling water pipe and the cylinder body to rotate. After this part of the flame retardant leaves its original position, the flame retardant above will fall through the gap of the spiral cooling water pipe, and the flame retardant carried away by the scraper will also fall after rotating to the upper part. In this way, all the flame retardants will contact the spiral cooling water pipe, with uniform cooling and high cooling efficiency.

[0015] Both ends of the spiral cooling water pipe of the present utility model have straight pipe heads that extend from the peripheral wall of the sealing cap, and the two straight pipe heads are screwed onto both ends of the spiral cooling water pipe, making the installation between the spiral cooling water pipe and the sealing cap convenient.

[0016] The central shaft of the present utility model is fixed to the two sealing caps. Fixing the central shaft to the ground foundation can complete the fixation of the sealing caps, and the relative movement between the cylinder body and the sealing caps can be conveniently realized. Keeping the spiral cooling water pipe stationary can facilitate the water circulation.

[0017] A cooling water channel is opened in the center of the present utility model, making the cooling effect better.

[0018] The spiral cooling water pipe of the present utility model is fixed to the central shaft. The central shaft can position the spiral cooling water pipe circumferentially, making it more convenient for the two end ports of the spiral cooling water pipe to align with the holes on the sealing cap for installing the straight pipe heads, and making the installation between the spiral cooling water pipe and the sealing cap more convenient.

[0025] To make the technical objectives, technical solutions and beneficial effects of the present utility model clearer, the technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model, that is, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings herein can be arranged and designed in various different configurations.

[0026] Specific embodiments of the flame retardant cooling device involved in the present utility model, in Figures 1-4It has a horizontal cylinder 1, and the cylinder 1 has an inlet and outlet 2. The inlet and outlet 2 is sealed with a sealing door (not shown in the figure). The sealing door is assembled in the same way as in the prior art. One side is hinged to the cylinder 1, and a handle is rotatably provided on the other side of the sealing door. A buckle for the handle to be engaged is provided on the cylinder. The inlet and outlet 2 is used to load materials into the cylinder 1 or discharge materials from the cylinder 1; two sealing caps 3 are provided at both ends of the cylinder 1, and the sealing caps 3 are rotatably matched with the cylinder 1. The sealing caps 3 are fixedly set on the ground. The structures of the two sealing caps are the same and the assembly method of the cylinder is the same; a spiral cooling water pipe 4 is provided in the cylinder 1, and a through hole 11 is opened on the sealing cap 3. The two ends of the spiral cooling water pipe 4 extend out of the two sealing caps 3 from the through holes 11 on the sealing cap 3, respectively. In this way, the two sealing caps 3 are fixed from the left and right ends respectively. A spiral cooling water pipe 4 is provided, and the spiral cooling water pipe 4 is used to contain cooling water, so as to cool the material in the cylinder 1; a scraper 5 is provided in the gap between the spiral cooling water pipe 4 and the cylinder 1, and the scraper 5 is fixed on the inner wall of the cylinder 1 and extends from one end of the cylinder 1 to the other end. When the cylinder 1 rotates, the scraper 5 rotates with the cylinder 1 to drive the material in the cylinder 1 to rotate in the cylinder 1; the cylinder 1 is driven to rotate by a power device (not shown in the figure), and the power device is a motor, which can be equipped separately in subsequent use.

[0027] Specifically, the cylinder 1 is connected to the power device through the annular friction surface 6 arranged on its outer circumferential surface. There are two annular friction surfaces 6, which are arranged at the two ends of the cylinder 1 respectively. The two annular friction surfaces 6 are symmetrical about the center line of the cylinder 1, that is, symmetrical in the axial direction. It can also be said that the two annular friction surfaces are equidistant from the corresponding ends. The annular friction surface 6 provides a force application point for the power device, which is convenient for the power device to drive the cylinder 1 to rotate relative to the sealing cap 3; the symmetrically arranged annular friction surfaces 6 make the cylinder 1 evenly stressed at both ends during the rotation process. When in use, the annular friction surface 6 meshes with the friction wheel of the power device for transmission, and the friction wheel is generally driven to rotate by a motor. This is a conventional driving method.

[0028] Specifically, the diameter of the friction surface 6 is larger than the outer diameter of the cylinder 1. In other words, the friction surface 6 is an annular surface convexly arranged on the outer periphery of the cylinder 1, which increases the torque, making it easier for the power device to drive the cylinder 1 to rotate; and when driving the cylinder 1 to rotate, it does not need to directly contact the cylinder 1, so that the friction wheel can be driven to rotate without interfering with the cylinder, so that the power device has a setting space.

[0029] Specifically, an annular retaining edge 7 is provided at both ends of the friction surface 6. That is to say, the two annular retaining edges 7 sandwich the friction surface 6 from the left and right sides, and the three of them together form an annular groove, in which the friction surface 6 is located at the bottom of the groove. In this way, when the power device drives the cylinder 1 to rotate, the force application point of the power device is always at the bottom of the annular groove, and it is not easy to deviate.

[0030] Specifically, both ends of the spiral cooling water pipe 4 are provided with straight pipe heads 8. The straight pipe heads 8 project outward from the peripheral wall of the sealing cap 3, and the two straight pipe heads 8 are screwed onto both ends of the spiral cooling water pipe 4. In this way, the spiral cooling water pipe 4 is convenient for installation and disassembly.

[0031] Specifically, a central shaft 9 is passed through the center of the spiral cooling water pipe 4. Both ends of the central shaft 9 pass through the two sealing caps 3 and are fixed to the two sealing caps 3. The central shaft 9 fixedly connects the two sealing caps 3 at both ends together, improving the stability of the device.

[0032] Specifically, the spiral cooling water pipe 4 is fixed to the central shaft 9.

[0033] Specifically, a cooling water channel 10 is opened in the center of the central shaft 9. The cooling water channel 10 cools the material in the cylinder 1 near the axis of the cylinder 1, which can further shorten the cooling time and improve the cooling efficiency.

[0034] Specifically, the sealing cap 3 is sleeved on the end head of the cylinder 1.

[0035] Specifically, the feeding and discharging port 2 is a long-shaped feeding and discharging port, and a sealing door is provided on the feeding and discharging port 2.

[0036] When in use, first connect the flame retardant cooling device. Then fix both ends of the central shaft 9 on a separately equipped bracket (not shown in the figure). The central shaft 9 is fixed on the ground foundation through the bracket. There should be enough space for the cylinder 1 to rotate between the annular retaining edges 7 at both ends of the friction surface 6 on the cylinder 1 and the ground foundation. The central shaft 9 is positioned by the bracket and does not rotate relative to the bracket. The two sealing caps 3 and the spiral cooling water pipe 4 are both fixed by the central shaft 9, and they are all fixed relative to the ground foundation. Then open the sealing door and put the flame retardant to be cooled into the cylinder 1 through the feeding and discharging port 2. Then close the sealing door, continuously introduce cooling water into the spiral cooling water pipe 4 and the cooling water channel 10 respectively. After that, start the power device to drive the cylinder 1 to rotate relative to the sealing cap 3. The scraper 5 in the cylinder 1 rotates with the cylinder 1 and drives the flame retardant in the cylinder 1 to rotate in the cylinder 1. During the rotation of the flame retardant in the cylinder 1, it will evenly contact the spiral cooling water pipe 4 and the cooling water channel 10. In this way, the flame retardant in the cylinder 1 is cooled. After the flame retardant is cooled, stop introducing the cooling water, turn off the power device to stop the rotation of the cylinder 1, then open the sealing door, and unload the cooled flame retardant from the feeding and discharging port 2.

[0037] In this embodiment, an annular friction surface is provided on the outer peripheral surface of the cylinder. This is a preferred technical solution. In other embodiments, it may not be provided, and the power device directly drives the cylinder to rotate through the outer peripheral surface of the cylinder.

[0038] In this embodiment, the diameter of the friction surface is larger than the outer diameter of the cylinder. This is a preferred technical solution. In other embodiments, the diameter of the friction surface may also be equal to the outer diameter of the cylinder.

[0039] In this embodiment, annular retaining edges are protrudingly provided at both ends of the friction surface, and they may not be provided in other embodiments.

[0040] In this embodiment, the two straight pipe heads are screwed onto both ends of the spiral cooling water pipe. In other embodiments, the two straight pipe heads may also be arranged at both ends of the spiral cooling water pipe in other ways, such as by insertion or clamping.

[0041] In this embodiment, a central axis is provided, which is a preferred technical solution. In other embodiments, it may not be provided, and instead, the two end caps are fixed on a separately provided bracket during use.

[0042] In this embodiment, the spiral cooling water pipe is fixed to the central axis. In other embodiments, the two may not be fixed.

[0043] In this embodiment, a cooling water channel is provided in the center of the central axis. In other embodiments, the cooling water channel may not be provided.

[0044] In this embodiment, the end cap is sleeved on the end of the cylinder body. In other embodiments, the end cap may also be inserted into the end of the cylinder body.

[0045] In this embodiment, the inlet and outlet are long-shaped. In other embodiments, the inlet and outlet may also be of other shapes, such as square or circular.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Any equivalent replacement and modification or partial replacement that do not deviate from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
