Abstract
Description
Technical Field
[0001] This utility model relates to the field of curing equipment technology, and in particular to a spray curing equipment for non-fired bricks. Background Technology
[0002] After molding, unfired bricks require curing. During the curing stage, industrial waste such as fly ash and coal gangue inside the bricks undergo a hydration reaction with water. If curing is lacking, the hydration reaction will be interrupted, leading to insufficient brick strength and easy pulverization. Therefore, curing is an essential step in the production of unfired bricks, directly affecting their performance and quality. The most common curing method used in industrial production is natural curing. Natural curing involves manually spraying water onto stacked bricks under natural conditions. This method is greatly affected by ambient temperature and humidity, has a long curing cycle, and makes it difficult to control the amount of water sprayed. The curing effect also relies heavily on manual experience and is difficult to control. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a spray curing equipment for non-fired bricks that has a simple structure, good curing effect, and wider adaptability.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is a spray curing device for non-fired bricks, including an outer cover and a bracket; the upper ends of both sides of the bracket are provided with grooves for placing trays; a number of branch pipes are installed at intervals on the outside of the outer cover; each branch pipe is located in the upper part and on both sides of the inner cavity of the outer cover and is connected to a number of spray pipes through pipes; atomizing nozzles are installed on the spray pipes; the number of branch pipes are all connected to the main pipe through connecting pipes; a steam generator is connected in parallel on the main pipe; a first control valve and a second control valve are respectively installed on the pipes connecting the main pipe and the steam generator in parallel.

[0006] Furthermore, an inclined plate is provided in the inner cavity of the bracket; one end of the circulation tube extends beyond the upper surface of the inclined plate.
[0007] Furthermore, a third control valve is installed on each of the branch pipes connecting to the main pipe.
[0008] Furthermore, a temperature and humidity sensor is installed on the inner wall of the outer cover.
[0009] Furthermore, the bottom of the bracket is equipped with wheels.
[0010] Furthermore, guide plates are placed between both sides of the bracket and the inner wall of the outer cover; several support blocks for supporting one end of the guide plates are fixed to the inner wall of the outer cover; and a groove is provided at the upper end of the outer wall of the bracket for abutting against one end of the guide plate.
[0011] Furthermore, a mixing hood is fixedly installed on the inner side of the outer cover; the mixing hood divides the inner cavity of the outer cover into two chambers; the spray pipe is located in the chamber outside the mixing hood; the mixing hood is made of a screen with a plurality of mesh openings.

[0013] Furthermore, a pressure sensor is installed inside the outer casing; a safety valve is installed on the outer casing.
[0014] The beneficial effects of this utility model are:
[0015] When the temperature is relatively high, curing is carried out by spraying. The second control valve is closed, and the first control valve is opened. The water pump draws water into the main pipe, which then enters several branch pipes and is sprayed out from the spray pipes through atomizing nozzles to spray the bricks. When the temperature is relatively low, curing is carried out by a mixture of spraying and steam. The first control valve, the second control valve, and the steam generator are opened simultaneously. The steam generated by the steam generator enters the main pipe through the steam output pipe and meets the water flowing into the main pipe to form a gas-liquid mixture. The gas-liquid mixture enters several branch pipes and is sprayed out from the spray pipes through atomizing nozzles to cure the bricks. By adjusting the ratio of the first and second control valves, the ratio of steam to water can be adjusted, thereby adjusting the temperature of the gas-liquid mixture. Compared with curing by spraying alone, curing by gas-liquid mixture can increase the temperature and provide a certain air pressure, promoting the contact between water and bricks and allowing water to penetrate into the bricks, thus shortening the curing cycle. This utility model has a simple structure, good curing effect, and wider adaptability. Attached Figure Description

Detailed Implementation
[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0022] Example 1
[0023] A spray curing device for non-fired bricks, such as Figure 1-3 As shown, it includes an outer cover 1 and a bracket 3; characterized in that: the upper ends of both sides of the bracket 3 are provided with grooves for placing the tray 4; a number of branch pipes 5 are installed at intervals on the outside of the outer cover 1; each branch pipe 5 is located in the upper part and on both sides of the inner cavity of the outer cover 1 and is connected to a number of spray pipes 6 through pipes; atomizing nozzles are installed on the spray pipes 6; the number of branch pipes 5 are all connected to the main pipe 7 through connecting pipes; a steam generator 9 is connected in parallel on the main pipe 7; a first control valve 14 and a second control valve 15 are respectively installed on the pipes connecting the main pipe 7 and the steam generator 9 in parallel.
[0024] The aforementioned non-fired brick spray curing equipment uses spraying for curing when the temperature is relatively high. The second control valve 15 is closed, and the first control valve 14 is opened. Water pump 10 draws water into the main pipe 7, which then flows into several branch pipes 5. The water is then sprayed from the spray pipes 6 through atomizing nozzles to spray the bricks. When the temperature is relatively low, a spraying and steam mixing method is used for curing. The first control valve 14, the second control valve 15, and the steam generator 9 are opened simultaneously. The steam generated by the steam generator 9 enters the main pipe 7 through the steam output pipe 8, where it meets the water flowing into the main pipe 7, forming a gas-liquid mixture. This gas-liquid mixture enters the several branch pipes 5 and is sprayed from the spray pipes 6 through atomizing nozzles to cure the bricks. By adjusting the ratio of the first control valve 14 to the second control valve 15, the ratio of steam to water can be controlled, thereby adjusting the temperature of the gas-liquid mixture. Using a gas-liquid mixture for curing, compared to simply using spraying, can increase the temperature and provide a certain air pressure, promoting the contact between water and the brick and allowing it to penetrate into the brick, thereby shortening the curing cycle.
[0025] Specifically, the bracket 3 has an inner cavity; the tray 4 is grid-shaped; a circulation pipe 13 is installed at the bottom of the bracket 3; the other end of the circulation pipe 13 is connected to the inlet of the sediment filter 12; the outlet of the sediment filter 12 is connected to the main pipe 7 via a pipe; a fourth control valve 17 is installed on the pipe connecting the sediment filter 12 and the main pipe 7; the main pipe 7 is also connected to an external water source via a first pipe 11; a fifth control valve 18 is installed on the first pipe; a water pump 10 is installed in the section of the main pipe 7 between the first control valve 14 and the fifth control valve 18. The grid-shaped tray 4 allows liquid to enter the inner cavity of the bracket 3 through the grid mesh of the tray 4 for collection, and the collected liquid is pumped back to the main pipe 7 for recycling, saving water resources. The sediment filter 12 is existing technology and can be directly purchased; its function is to filter out sediment from the liquid.
[0026] Specifically, a third control valve 16 is installed on the connecting pipe of each branch pipe 5 to the main pipe 7. The flow rate into the corresponding branch pipe 5 can be adjusted by regulating the third control valve 16.
[0027] Specifically, a temperature and humidity sensor 20 is installed on the inner wall of the outer cover 1.
[0028] Specifically, the bottom of the bracket 3 is equipped with a traveling wheel 22.

[0030] Specifically, guide plates 19 are placed between both sides of the bracket 3 and the inner wall of the outer cover 1; several support blocks for supporting one end of the guide plates 19 are fixed to the inner wall of the outer cover 1; and a groove is provided at the upper end of the outer wall of the bracket 3 for abutting against one end of the guide plates 19. The function of the guide plates 19 is to guide the water falling from the spray into the inner cavity of the bracket 3, thus saving water resources.
[0031] Specifically, a pressure sensor is installed inside the outer cover 1; a safety valve is also installed on the outer cover 1. Doors that can be opened and closed are located at both ends of the outer cover 1. After all the bricks are installed and pushed into the inner cavity of the outer cover 1, the doors at both ends of the outer cover 1 are closed. During the curing process, if the pressure inside the outer cover 1 reaches or exceeds the set value of the safety valve, the safety valve will automatically open to release pressure, preventing excessive pressure from causing the outer cover 1 to deform or even explode.

[0033] A spray curing device for non-fired bricks, such as Figure 4 As shown, compared to Embodiment 1, a mixing cover 2 and an inclined plate 21 are added, while the rest of the structure is the same as in Embodiment 1.
[0034] Specifically, a mixing hood 2 is fixedly installed on the inner side of the outer cover 1; the mixing hood 2 divides the inner cavity of the outer cover 1 into two chambers; the spray pipe 6 is located in the chamber outside the mixing hood 2; the mixing hood 2 is made of a screen with several mesh openings. The function of the mixing hood 2 is to make the liquid or gas-liquid mixture more dispersed and more evenly distributed, thereby improving the curing effect.
[0035] Specifically, an inclined plate 21 is provided in the inner cavity of the bracket 3; one end of the circulation pipe 13 extends beyond the upper surface of the inclined plate 21. The function of the inclined plate 21 is to allow large pieces of debris or gravel to roll along the inclined plate 21 and accumulate at the lower end of the inclined plate 21 for easy cleaning.
