Description

Technical Field

[0001] The utility model relates to the technical field of flat collector production, and particularly relates to a thermal insulation foaming device for a flat collector. Background Technique

[0002] A flat collector is the main component in a solar water heater for absorbing solar energy and converting it into heat energy. The heat absorption element of the flat solar collector is a metal heat absorption plate (usually copper or aluminum), and the surface of the heat absorption plate is a solar selective absorption coating; the middle of the heat absorption plate is a medium flow channel. A collector is composed of several heat absorption plates and upper and lower collector tubes welded together, with a metal outer frame and a back thermal insulation material, and high-transmittance glass on the top. When producing the back thermal insulation material of the flat collector, a thermal insulation foaming device is required. The thermal insulation foaming device is a device that converts liquid materials into foamed materials and is widely used in fields such as construction, aerospace, automobiles, and electronics. Its working principle is to send liquid materials into a mixer through a high-pressure pump, add a catalyst and gas, mix them evenly, and then carry out a foaming reaction within a certain period of time to generate a large number of bubbles, thereby converting the liquid materials into foam-like materials. This foamed material can be adjusted according to the required density and hardness.

[0003] The existing technology has the following deficiencies: When the existing thermal insulation foaming device adds thermal insulation materials to the inside of the flat collector, it cannot conveniently add the foamed materials evenly to the inside of the flat collector, and at the same time, it cannot level the foamed thermal insulation materials, making the thermal insulation materials prone to uneven thickness and easy to have gaps with the inner wall of the flat collector, which will affect the thermal insulation effect of the thermal insulation materials. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a thermal insulation foaming device for a flat collector. Through a feeding hose, the thermal insulation materials in the storage barrel can be transported to the inside of the flat collector through a discharge nozzle. When the first hydraulic cylinder works, the height of the scraper can be adjusted. The movement of the movable frame enables the scraper to level the foamed thermal insulation materials, so that the thermal insulation materials can be evenly added to the inside of the flat collector to solve the above deficiencies in the technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A thermal insulation foaming device for a flat collector, including a fixing mechanism for fixing the flat collector, and further including:

[0006] A leveling mechanism, arranged on the top of the fixing mechanism, for leveling the foamed thermal insulation materials;

[0007] A foaming mechanism, arranged inside the leveling mechanism, for foaming the thermal insulation materials inside the flat collector;

[0008] The leveling mechanism includes a movable frame arranged on the outer wall of one side of the fixing mechanism. At both ends of the top of the movable frame, first hydraulic cylinders are fixedly installed. On the piston rods of both first hydraulic cylinders, mounting plates are provided. At the bottoms of both mounting plates, scraping plates are fixedly installed.

[0009] The foaming mechanism includes a storage cylinder fixedly installed on the outer wall of one side of the movable frame. Inside the storage cylinder, a feeding hose provided with a vacuum pump is fixedly installed. At the bottom of the side of the feeding hose away from the storage cylinder, a discharging nozzle is fixedly installed. The outside of the discharging nozzle is fixedly sleeved with a fixing plate located between the two mounting plates. At both ends of one side of the fixing plate, second hydraulic cylinders are provided.

[0010] Preferably, the fixing mechanism includes a support frame. On the top of the support frame, a placement plate is fixedly installed. On the outer wall of one side of the support frame, a control box is fixedly installed. Inside the top wall of the placement plate, a mounting groove is opened.

[0011] Preferably, a first lead screw is rotatably installed on the inner wall of the mounting groove. At one end of the first lead screw, a first motor is provided. On the outer walls of both ends of the first lead screw, clamping plates that are movably connected to the outer wall of the flat plate solar collector are threadedly sleeved.

[0012] Preferably, a second lead screw is rotatably installed on the inner wall of one side of the placement plate. At one end of the second lead screw, a second motor is provided. The outer wall of the second lead screw is threadedly connected to the inner wall of one side of the bottom of the movable frame. Limited grooves are opened on the inner walls of both ends of the movable frame.

[0013] Preferably, on the outer walls of both sides of the two mounting plates close to the movable frame, movable seats are fixedly installed. The tops of the two movable seats are respectively fixedly connected to the piston rods of the two first hydraulic cylinders.

[0015] In the above technical solution, the technical effects and advantages provided by the present utility model:

[0016] 1. The thermal insulation material inside the storage cylinder can be added to the inside of the flat plate collector through the feeding hose and the discharging nozzle, so that the thermal insulation material can foam inside the flat plate collector. The two second hydraulic cylinders work to move the discharging nozzle longitudinally, and at the same time, the second lead screw works to enable the discharging nozzle to move horizontally inside the flat plate collector. At the same time, the two first hydraulic cylinders work to adjust the height of the scraper, and the second lead screw works to enable the scraper to level the foamed thermal insulation material, so that the thermal insulation material can be evenly filled into the flat plate collector, ensuring the working effect of the thermal insulation material;

[0017] 2.

[0028] The present utility model provides a thermal insulation foaming device for a flat plate collector as shown in Figure 1 which includes a fixing mechanism 1 for fixing the flat plate collector, and further includes:

[0029] A flattening mechanism 2 is arranged on the top of the fixing mechanism 1 and is used for flattening the foamed thermal insulation material.

[0030] A foaming mechanism 3 is arranged inside the flattening mechanism 2 and is used for foaming the thermal insulation material inside the flat plate collector.

[0031] In order to conveniently flatten the foamed thermal insulation material, as shown in Figures 1 - 2 and Figure 5 , the flattening mechanism 2 includes a movable frame 203 arranged on the outer wall of one side of the fixing mechanism 1. Both ends of the top of the movable frame 203 are fixedly installed with first hydraulic cylinders 205. The piston rods of the two first hydraulic cylinders 205 are both provided with mounting plates 207. Both bottoms of the two mounting plates 207 are fixedly installed with scrapers 208. When the two first hydraulic cylinders 205 work, the height of the scraper 208 can be adjusted so that it can contact the foamed thermal insulation material. At the same time, the transverse movement of the movable frame 203 enables the scraper 208 to perform a flattening operation on the thermal insulation material.

[0032] In order to evenly add the thermal insulation material into the flat plate collector, as shown in Figures 1 - 5 , the foaming mechanism 3 includes a material storage cylinder 301 fixedly installed on the outer wall of one side of the movable frame 203. A feeding hose 302 provided with a vacuum pump is fixedly installed on the inner wall of the material storage cylinder 301. The bottom of the side of the feeding hose 302 away from the material storage cylinder 301 is fixedly installed with a discharge nozzle 303. A fixed plate 304 located between the two mounting plates 207 is fixedly sleeved outside the discharge nozzle 303. Both ends of one side of the fixed plate 304 are provided with second hydraulic cylinders 306. When the two second hydraulic cylinders 306 work, the discharge nozzle 303 can move longitudinally, and at the same time, the transverse movement of the movable frame 203 can drive the discharge nozzle 303 to move transversely, so as to evenly add the thermal insulation foaming material into the flat plate collector.

[0033] To conveniently add thermal insulation materials inside flat plate collectors of different sizes, such as Figures 1 - 2 and Figure 4 shown, the fixing mechanism 1 includes a support frame 101. A placement plate 102 is fixedly installed at the top of the support frame 101. A control box 103 is fixedly installed on one outer wall of the support frame 101. An installation groove 104 is formed in the inner wall of the top of the placement plate 102. A first lead screw 105 is rotatably installed in the inner wall of the installation groove 104. A first motor 106 is arranged at one end of the first lead screw 105. Clamping plates 107 that are movably connected to the outer wall of the flat plate collector are threadedly sleeved on the outer walls of both ends of the first lead screw 105. When the first motor 106 works, the first lead screw 105 rotates, and then the two clamping plates 107 can move relatively or away from each other on the outside, so that the two clamping plates 107 can clamp and fix flat plate collectors of different sizes.

[0034] To make the scraping plate 208 stable during height adjustment, as Figure 2 and Figure 5 shown, a second lead screw 201 is rotatably installed in the inner wall of one side of the placement plate 102. A second motor 202 is arranged at one end of the second lead screw 201. The outer wall of the second lead screw 201 is threadedly connected to the inner wall of one side of the bottom of the movable frame 203. Limiting grooves 204 are formed in the inner walls of both ends of the movable frame 203. Movable seats 206 are fixedly installed on the outer walls of the two mounting plates 207 close to the movable frame 203. The tops of the two movable seats 206 are respectively fixedly connected to the piston rods of the two first hydraulic cylinders 205. The outer walls of the two movable seats 206 are respectively movably connected to the inner walls of the two limiting grooves 204. Movable grooves 209 are formed in the inner walls of the two mounting plates 207 close to each other. The limiting grooves 204 can limit the movement of the movable seats 206, so that the mounting plates 207 and the scraping plate 208 are stable during height adjustment.

[0035] To make the discharge nozzle 303 stable during longitudinal movement, as Figures 2 - 3 and Figure 5 shown, two second hydraulic cylinders 306 are respectively fixedly installed on one outer wall of the two mounting plates 207. Sliders 305 are fixedly installed on the piston rods of the two second hydraulic cylinders 306. The outer walls of the two sliders 305 are respectively movably connected to the inner walls of the two movable grooves 209. The two sliders 305 are respectively fixedly installed on the outer walls of both ends of the fixing plate 304. The movable grooves 209 can limit the movement of the adjacent sliders 305, so that the fixing plate 304 can stably move between the two mounting plates 207, and then the discharge nozzle 303 can stably move longitudinally.

[0036] When foaming the thermal insulation material inside the flat plate collector, the flat plate collector is placed on the top of the placing plate 102. By operating the control box 103, the first motor 106 works, which can drive the first lead screw 105 to rotate, so that the two clamping plates 107 move relative to or away from each other along the inner wall of the installation groove 104 on their outer sides, and then the flat plate collector can be clamped and fixed. Then, by operating the two first hydraulic cylinders 205, the two movable seats 206 can be driven to move along the inner wall of the adjacent limiting groove 204, so that the height of the installation plate 207 and the scraper 208 can be adjusted, and then the height of the discharge nozzle 303 can be adjusted. By operating the feeding hose 302 with a vacuum pump, the thermal insulation material and the foaming agent inside the storage cylinder 301 can be transported to the discharge nozzle 303, and then the thermal insulation material and the foaming agent can be added into the flat plate collector through the discharge nozzle 303. At the same time, by operating the two second hydraulic cylinders 306, the two sliders 305 can move along the inner wall of the adjacent movable groove 209, so that the fixed plate 304 drives the discharge nozzle 303 to move longitudinally. At the same time, by operating the second motor 202, the second lead screw 201 rotates, so that the movable frame 203 moves along the outer wall of one side of the placing plate 102, so that the discharge nozzle 303 can evenly add the thermal insulation material into the flat plate collector. At the same time, the transverse movement of the movable frame 203 enables the two scrapers 208 to level the foamed thermal insulation material, so that the thermal insulation material can be evenly filled into the flat plate collector, which can ensure the working effect of the thermal insulation material. This embodiment specifically solves the problem in the prior art that the thermal insulation material cannot be evenly added into the flat plate collector and the foamed thermal insulation material cannot be leveled, which will affect its working effect.

[0037] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
