Description

Technical Field

[0001] The invention relates to the technical field of template processing, in particular to an environmentally friendly circulating purification device for oiling calcium silicate board templates. Background Art

[0002] Calcium silicate board is a key component of my country's cement products industry. As a key fiber-cement-based composite material, it is widely used in commercial building ceilings, floor slabs, partitions, exterior walls, and interior fireproofing, gradually becoming one of the leading board materials in the construction industry.

[0003] Steel formwork is required in the production of calcium silicate boards to prevent deformation of the wet blank and ensure its surface is flat and smooth. After pressing the wet blank, the steel formwork will stick to the material. In order to ensure the reusability of the steel formwork, it is very important to clean the steel formwork. The existing technology is to place the steel formwork removed from the sampling demoulding machine on a conveyor roller table, clean its surface during the conveyance of the steel formwork, and then apply a release agent to the surface of the formwork by spraying (the oiling is to form an isolation layer between the formwork and the wet blank to prevent sticking). The release agent and the formwork are then flattened and applied using a roller. After the application is completed, the steel formwork is collected and used.

[0004] The above operation does not have a device for treating the falling wastewater in the flushing process, and does not have a device for collecting and utilizing the overflowed release agent in the coating process. In order to promote the green transformation of the building materials industry, promote green transformation and achieve positive development, it is particularly important to design a device that can not only clean the template but also recycle the cleaning wastewater.

DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] Combined with attachment Figure 1 and attached Figure 2As shown, an environmentally friendly circulating purification device for oiling calcium silicate board templates includes a conveying roller platform 1, which is composed of a supporting frame 111, a plurality of equidistantly arranged conveying rollers 112 and a transmission mechanism, and the transmission mechanism drives the plurality of conveying rollers 112 to rotate synchronously. The above features belong to the prior art. A cleaning component 2, a drying component 3 and an oiling component 4 for cleaning, drying and oiling the template surface are sequentially provided on the supporting frame 111 along the conveying direction. A water receiving trough 113 and an oil receiving trough 114 are respectively provided on the supporting frame 111 corresponding to the cleaning component 2 and the oiling component 4. In order to avoid the influence of wastewater or release agent on the transmission mechanism, the rotating shaft of the conveying roller 112 is rotatably connected to the side walls of the water receiving trough 113 and the oil receiving trough 114 and is sealed with a rotary sealing gasket. This can prevent the wastewater and release agent from flowing out of the water receiving trough 113 and the oil receiving trough 114 and then flowing onto the transmission mechanism during the process of flushing and oiling the template.

[0032] On the ground, along the conveying direction, a wastewater treatment component 5, a release agent preparation component 6, and a collection tank 7 are sequentially arranged. The water receiving trough 113 is connected to the input port of the wastewater treatment component 5 via a first pipe 115, and the output port of the wastewater treatment component 5 provides water to the release agent preparation component 6. The oil receiving trough 114 is connected to the collection tank 7 via a second pipe 116.

[0033] The support frame 111 is provided with a control component 1 8 and a control component 2 9 for automatically starting or stopping the operation of the cleaning component 2 and the oiling component 4. During the forward transmission of the template, the control component 1 8 and the control component 2 9 are triggered or released to start or stop the operation of the cleaning component 2 and the oiling component 4.

[0034] Through the above structure, the demoulding template is placed on the conveying roller 112, and the conveying roller 112 drives the template to be conveyed forward during its rotation. When it is conveyed to the cleaning component 2, the control component 18 is triggered to act, and the cleaning component 2 is automatically turned on to rinse the sticky objects on the surface of the template. When the template passes the cleaning component 2, the action of the control component 18 is released, and the cleaning component 2 is stopped. The cleaned template continues to be conveyed forward, and its surface is dried by the drying component 3. When the template is conveyed to the oiling component 4, the control component 29 is triggered to act, and the oiling component 4 is automatically turned on to oil the surface of the template. When the template passes the oiling component 4, the action of the control component 29 is released, and the oiling component 4 is stopped. This increases the convenience of starting and stopping control of the cleaning component 2 and the oiling component 4.

[0035] The wastewater generated during the cleaning process falls into the water receiving tank 113, and then falls into the wastewater treatment component 5 for treatment. The qualified water after treatment is injected into the release agent preparation component 6 for use. The release agent overflowed during the oiling process falls into the oil receiving tank 114, and then falls into the collection tank 7 for recycling.

[0036] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, the cleaning assembly 2 includes a connecting plate 211 disposed on the top surface of the water receiving tank 113, a pressure water pipe 212 is provided on the connecting plate 211, and a plurality of high-pressure nozzles 213 are provided on the pressure water pipe 212, and the pressure water pipe 212 is connected to the output end of an external water pump 214;

[0037] In order to realize automatic control of the start and stop of the water pump 214, the control component 8 includes a slide bar 811 with a rebound function corresponding to the pressure water pipe 212 and arranged in a sliding symmetrical manner on both sides of the water receiving trough 113. The inner ends of the two slide bars 811 are provided with a U-shaped frame 812 and a guide roller 813 is rotatably provided on this U-shaped frame 812. The template is located between the two guide rollers 813, and the front and rear ends of the template are located between the axis and the inner end surface of the two guide rollers 813. In this way, during the transmission of the template, the two guide rollers 813 will be pushed to slide back to back. A switch 814 for controlling the start and stop of the water pump 214 is provided on the inner wall of the support frame 111 at a position corresponding to the slide bar 811 away from the transmission mechanism. The switch 814 is electrically connected to the water pump 214 through a wire, and the switch 814 is a momentary switch. The contacts of this momentary switch correspond to the slide bar 811.

[0038] The working principle of control component 18 is that when the template is transferred to the external position of guide roller 1 813, it will drive the guide rollers 1 813 at both ends to move away from each other, and at the same time drive the slide bars 811 at both ends to move away from each other. The movement of the slide bars 811 will abut against the switch 1 814 and drive this switch 1 814 to operate. Then, the water pump 1 214 will be activated to transfer the external water source to the pressure water pipe 212, and then spray it onto the surface of the template through the high-pressure nozzle 213 for cleaning.

[0039] When the template is transferred over the guide roller 813, the abutment force on the guide roller 813 is released, and the slide bar 811 automatically rebounds and resets, thereby releasing the external force on the switch 814. At this time, the switch 814 automatically resets, and then the rotation of the water pump 214 stops, and the flushing of the template is completed.

[0040] Combined with attachment Figure 5 , Attachment Figure 6 and attached Figure 7As shown, the oiling assembly 4 includes an inverted U-shaped frame 411 arranged on the support frame 111, an oil pipe 412 is provided on the bottom surface of the U-shaped frame 411, and a plurality of oil outlet holes are opened on the oil pipe 412 at equal intervals, and fixed seats 413 are symmetrically provided on both sides of the support frame 111 on the right side of the oil pipe 412, and an oiling roller 414 tangential to the top surface of the template is provided between the two fixed seats 413 for common rotation, and the oiling roller 414 is made of silicone material, and the oil pipe 412 is connected to the output end of the external feed pump 415, and the input end of the feed pump 415 is connected to the release agent preparation assembly 6 through an oil pipe;

[0041] In order to realize automatic control of the start and stop of the feed pump 415, the control component 9 includes a support seat 911 and a swing arm 912. The support frame 111 is connected to a support seat 911 below the top surface of the conveying roller 112 at the corresponding position of the oil pipe 412. Half shafts 913 are symmetrically fixed on both sides of the support seat 911. The middle of the two swing arms 912 are hinged to the corresponding half shafts 913 respectively. A torsion spring is provided on the half shaft 913 to give the swing arm 912 a rebound function, and a guide roller 914 is provided on the top surface of the two swing arms 912 for common rotation. The two sides of the bottom end of any swing arm 912 are hinged with a swing plate 915, and the bottom end of the other swing arm 912 is connected to the support seat 9 by the cooperation of an arc-shaped slide groove and an arc-shaped slider. 11, two swing plates 915 are hinged with guide rods 916, and a guide seat 917 for sliding the guide rods 916 is fixedly provided on the support seat 911, and a switch 918 for controlling the start and stop of the feed pump 415 is provided on the support seat 911 corresponding to the guide rods 916. The switch 918 is electrically connected to the feed pump 415 through a wire, and the switch 918 is a momentary switch, and the top surface height of the guide roller 914 is greater than the top surface height of the conveying roller 112. During the template transmission process, the guide roller 914 will be driven to swing downward, and auxiliary rollers 919 are respectively rotated between the two ends of the support seat 911 and the inner wall of the support frame 111, and the top surface of the auxiliary roller 919 is flush with the top surface of the conveying roller 112.

[0042] The principle of the control component 2 9 is that when the template is transferred to the guide roller 2 914, it will drive the guide roller 2 914 to swing downward, and at the same time drive the swing arm 912 to swing downward. Under the action of the hinged swing plate 915, it will drive the guide rod 916 to slide upward, and then abut the switch 2 918, causing the switch 2 918 to operate. Then, the material delivery pump 415 will be started to deliver the mold release agent to the oil delivery pipe 412, and then it will fall onto the surface of the template through the oil outlet hole. Then, it will be smeared on its surface by the oil coating roller 414.

[0043] When the template passes the guide roller 2 914, the external force on the guide roller 2 914 is eliminated, and under the action of the torsion spring, the swing arm 912 and the guide roller 2 914 are automatically driven to swing upward and reset, and then the guide rod 916 is driven to move downward, and the contact force on the switch 2 918 is released. At this time, the switch 2 918 will automatically reset, and then the rotation of the feed pump 415 will stop, and the oiling of the template surface is completed.

[0044] Combined with attachment Figure 1 , Attachment Figure 8 , Attachment Figure 9 and attached Figure 10 As shown, in order to remove water droplets from the template surface after cleaning, supports 117 are symmetrically provided on both sides of the support frame 111 near the left side of the drying assembly 3. Water absorption rollers 118 that contact the top surface of the template are provided on the two supports 117 to rotate together. The water absorption rollers 118 are driven to rotate during the template transportation process. When the water absorption rollers 118 are in contact with the template surface, the water droplets on the surface are absorbed.

[0045] In order to thoroughly remove moisture from the surface of the template to avoid affecting the oiling, the drying component 3 includes a shell 311 arranged on the support frame 111 and having a straight slot structure, an air outlet 312 is provided on the upper inner wall of the shell 311 along its circumferential direction, and a guide plate 313 is also provided on the inner wall of the shell 311 for guiding the air outlet 312, and the guide plate 313 guides the hot air at the air outlet 312 downward, an air outlet 314 is provided on the shell 311 corresponding to the water absorption roller 118, and a guide plate 315 is also provided on the shell 311 for guiding the air outlet 314, and the guide plate 315 guides the hot air from the air outlet 314 toward the water absorption roller 118, and an air inlet 316 is provided on the end of the shell 311, and the air inlet 316 is connected to an external hot air unit.

[0046] The working principle of the drying component 3 is to start the hot air unit and transmit the hot air to the shell 311 through the air inlet 316. At this time, the hot air will be discharged from the air outlet 1 312 and the air outlet 2 314. The hot air discharged from the air outlet 1 312 is transmitted downward by the guide plate 1 313. At this time, the gas flow rate at the air outlet 1 312 increases and the pressure decreases. Under the action of Bernoulli's principle, an ejection effect is formed. At this time, the gas in the upper part of the shell 311 will be quickly pushed to the air outlet 1 312 and transmitted to the surface of the template together with the hot air to dry the template surface. In this way, the amount of hot air on the template surface can be increased under the condition of the same power of the hot air unit, thereby improving the drying effect on the template surface.

[0047] The hot air discharged from the second air outlet 314 is transferred to the surface of the water-absorbing roller 118 through the second guide plate 315 to dry the water-absorbing roller 118, so that the water-absorbing roller 118 and the template surface can be dried synchronously.

[0048] Combined with attachment Figure 1 As shown, the wastewater treatment component 5 includes a water tank 511, a regulating tank 512, a coagulation tank 513, a flocculation tank 514, a filter tank 515 and a reuse tank 516 which are sequentially arranged on the ground and distributed in a stepped manner, and a connecting tank is sequentially provided between the water tank 511, the regulating tank 512, the coagulation tank 513, the flocculation tank 514, the filter tank 515 and the reuse tank 516. The regulating tank 512 is provided with a water pipe for injecting clean water. The water receiving tank 113 is connected to the water tank 511 through a pipe 115. The water in the reuse tank 516 is transported to the release agent preparation unit by an external water pump. In component 6, the release agent preparation component 6 includes a material tank 611 and a stirring mechanism in the material tank 611. The water in the recycling pool 516 is injected into the material tank 611. The input end of the feed pump 415 is connected to the material tank 611. The bottom walls of the water receiving trough 113 and the oil receiving trough 114 are inclined toward the water trough 511 and the oil receiving trough 114 respectively, and are close to the water trough 511 and the oil receiving trough 114 as the lower end and connected to pipe 1 115 and pipe 2 116. In this way, waste water or overflowed deoiling agent can quickly flow into the water trough 511 and the oil receiving trough 114.

[0049] The working principle of the wastewater treatment component 5 is that the wastewater after cleaning the template flows into the water receiving tank 113, and then flows into the water tank 511, and flows into the regulating tank 512 through the water tank 511, mainly to mix the wastewater and clean water in a certain proportion. The regulating tank 512 is mainly used to achieve uniform water quality and water volume, so as to facilitate the continuous operation of subsequent equipment; the water quality regulated by the regulating tank 512 flows into the coagulation tank 513, and the coagulation tank 513 contains polyaluminum chloride, which forms stable ions or hydroxide colloids through hydrolysis reaction, neutralizes the charge in the sewage, and forms small molecular cell agglomerates with the charged substances, so as to avoid the formation of difficult-to-remove suspended colloidal particles in the sewage as much as possible. And ensure the turbidity and chromaticity of the treated sewage; the water treated in the coagulation tank 513 flows into the flocculation tank 514, in which a certain amount of polyacrylamide is added for treatment. Polyacrylamide has flocculation, adhesion, resistance reduction and thickening effects. It causes the suspended impurities in the sewage to undergo electrical neutralization reaction, and can greatly reduce the resistance between the sewage, thereby increasing the consistency of the coagulated flocs, causing a large amount of flocculent alum to precipitate in the sewage, and enhancing the solid-liquid precipitation and separation effect; the water after flocculation flows into the filter tank 515, which contains a filter, and the filtered water flows into the reuse tank 516. The pH value of the wastewater treated by the wastewater treatment system is between 6-9, and the COD is less than 500mg / L.

[0050] During the specific implementation of the present invention, the demoulding template is first placed on the conveying roller 112. When the template is conveyed to the guide roller 1 813, the slide bar 811 is driven to slide outward, so that the slide bar 811 abuts against the switch 1 814 to operate, thereby controlling the start of the water pump 1 214, and the high-pressure nozzle 213 is used to rinse the template surface. After the rinsing is completed, the template surface is dried by the drying component 3. When the dried template is conveyed to the guide roller 2 914, the switch 2 918 is driven to operate, so that the feed pump 415 is started to apply paint to the template surface.

[0051] The wastewater generated during the cleaning process is treated by the wastewater treatment component 5, and the qualified water after treatment is injected into the material tank 611 for use. The release agent overflowed during the oiling process falls into the collection tank 7 for recycling, thereby improving the environmental friendliness of the device.

[0052] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs structures and embodiments similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
