Description

Technical Field

[0001] The present invention relates to a one-way plate stacking pressure-controlled solar hot air space, which performs hot air pressurization and pressure control in a fully natural passive manner. Hot air can be input into the hot air space, and the quality and pressure of the hot air can be increased, and the pressure value can be controlled within a certain range. It can be applied to civil, agricultural and industrial occasions that require hot air, utilize solar energy, and comprehensively utilize renewable energy. It belongs to the field of solar energy technology and related environmental protection and energy-saving technologies. Background Art

[0002] In the industrial and civil fields, renewable energy technology systems such as solar energy often appear in the form of active and passive hybrids, as well as comprehensive utilization systems of multiple energy technologies. The ultimate design concept is a fully natural passive system, which has the best energy, environmental and resource effects.

[0003] Solar thermal air technology systems are used in many industrial and civil applications. These applications often require hot air at a certain pressure and have certain continuity requirements for the hot air flow. Solar thermal air systems often need to be pressurized to a certain pressure range before they can be used in actual working conditions.

[0004] The rational operation of solar energy technology systems requires parameter control in many cases. In fact, industrial and civil technology systems are mostly composite systems of equipment systems and automatic control systems. The pressure control system of solar hot air is a "secondary technology system" of the solar energy technology composite overall system. In order to achieve the most reasonable and optimized way of energy, environment and resources, its control system should also be designed with all-natural, passive and zero-energy technical requirements as the limit of the concept.

[0005] The all-natural passive system has the best energy, environmental and resource effects. The design concept of the entire engineering technology system and all its subsystems should be all-natural, passive and zero energy consumption. Only in this way can the best energy, environmental and resource effects be achieved. But in reality, its development and application are not enough.

[0006] Generally speaking, the control of solar energy technology systems mostly adopts active power-consuming electrical or digital control systems. The development and application of zero-energy, all-natural and passive control systems designed with the concept of full system and all-natural is still insufficient. That is, the design and development of passive control of the control system of solar energy technology system is insufficient. Not only is it neglected in concept, but the development of its technical measures also has certain difficulties and shortcomings. It is necessary to develop and apply reasonable and optimized technical measures.

[0007] Therefore, the related passive zero-energy solar hot air boost pressure control system has a large application space. How to generate hot air within a set pressure range in a fully natural passive way is a technical problem with a certain degree of difficulty. Similarly, on the other hand, the related technical system has considerable development and application space. Summary of the invention

[0008] In view of the above difficulties and shortcomings, the present invention provides a one-way plate stacking pressure controlled solar hot air space, which can input hot air into the hot air space, and can achieve the quality and pressure increase of the hot air, and at the same time can control its pressure value within a certain range.

[0009] The technical solution of the present invention is:

[0010] A one-way plate stacking pressure controlled solar thermal air space, the system composition of which is:

[0011] The following components are based on the system process and functions of each part:

[0012] It consists of a solar hot air inlet duct 2, a one-way pressure-controlled base sealing plate 3, a solar hot air boosting space 1, a hot air opening and closing outlet 8; a one-way pressure-controlled base plate rotation pivot 5, a one-way pressure-controlled base plate rotation wall groove 6, a one-way pressure-controlled base plate rotation pivot wall frame 7, a one-way pressure-controlled base plate rotation pivot opening 8; a one-way pressure-controlled superimposed sealing plate 4, an inner wedge-shaped groove 10 on the back of the plate, and an outer wedge-shaped convex strip 11 on the front of the plate.

[0013] The system structure is:

[0014] The outside air heating intake structure is:

[0015] The solar hot air inlet duct 2 is connected to the solar hot air pressurized space 1 .

[0016] The hot air taking channel structure is:

[0017] The solar hot air pressurization space 1 is provided with a hot air opening and closing outlet 8 connected thereto.

[0018] The one-way pressure-controlled base sealing plate 3 is arranged in the following structure:

[0019] The upper end of the one-way pressure-controlled base sealing plate 3 has a hole and a built-in one-way pressure-controlled substrate rotating pivot 5, the one-way pressure-controlled substrate rotating pivot 5 is connected to the one-way pressure-controlled substrate rotating pivot wall frame 7, and the upper end of the one-way pressure-controlled base sealing plate 3 is built into the one-way pressure-controlled substrate rotating wall groove 6. The plate surface on the indoor space side of the one-way pressure-controlled base sealing plate 3 is provided with a wedge-shaped groove 10 on the back of the plate. In this way, the one-way pressure-controlled base sealing plate 3 is connected to the one-way pressure-controlled superimposed sealing plate 4. The connection method is that the inner wedge-shaped groove 10 on the back of the plate of the one-way pressure-controlled base sealing plate 3 overlaps with the outer wedge-shaped convex strip 11 on the front of the plate of the one-way pressure-controlled superimposed sealing plate 4 in a concave-convex buckling manner.

[0020] The length and width of the one-way pressure-controlled base sealing plate 3 are both greater than the maximum length and width of the corresponding hot air inlet channel. It can be ensured that when the plate surface naturally falls to a plumb state, the plate surface can cover and seal the hot air inlet of the solar hot air inlet duct 2 formed by the opening of the south wall. The one-way pressure-controlled base sealing plate 3 will not rotate outwardly toward the south wall to form a hot air inlet, but can only rotate inwardly toward the south wall to form a hot air inlet.

[0021] The one-way pressure control superimposed sealing plate 4 is arranged in the following structure:

[0022] The plate surface of the one-way pressure-controlling superimposed sealing plate 4 on the indoor space side is provided with an inner wedge-shaped groove 10 on the back of the plate, and at the same time, the side thereof facing the one-way pressure-controlling base sealing plate 3 is provided with an outer wedge-shaped convex strip 11 on the front of the plate. The one-way pressure-controlling superimposed sealing plate 4 can be connected with the one-way pressure-controlling base sealing plate 3 in a concave-convex overlap manner. At the same time, two one-way pressure-controlling superimposed sealing plates 4 can be connected in the same manner. In this way, the number of plates of the one-way pressure-controlling superimposed sealing plates 4 can be increased or decreased according to the setting of the pressure range value.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is based on the internal and external composition, structure and structural relationship of the one-way plate stacking pressure controlled solar hot air space mentioned above. On the above basis, the present invention can achieve the quality and pressure increase of hot air, and at the same time can passively control its pressure value within a certain range. Its technical system implements and applies a passive zero-energy mechanical pressure automatic control system.

[0028] The technical principle of the present invention is:

[0029] The opening principle of the channel for hot air to enter the hot air space is:

[0030] When the hot air in the solar hot air inlet pipe 2 reaches a sufficient pressure, the outer plate surface of the one-way pressure-controlled base sealing plate 3 can be pushed open to form a hot air inlet channel, so that the hot air enters the solar hot air pressurized space 1.

[0031] The principle of the one-way pressure-controlled base sealing plate 3 opening inwards is:

[0032] The hot air inlet channel of the solar hot air boosting space 1 is composed of the outlet of the solar hot air inlet pipe 2, the inner plate surface of the one-way pressure control base sealing plate 3 which is rotated inward to a certain angle around the one-way pressure control base plate rotation pivot 5 in a non-plumb position, and the inner surface of the south wall of the solar hot air boosting space 1.

[0033] When the thrust of the hot air on the outer plate surface of the one-way pressure control base sealing plate 3 is sufficient to push the pressure control plate to rotate around the one-way pressure control base plate rotation pivot 5 into the solar hot air boosting space 1, the hot air inlet is formed, and the hot air enters the solar hot air boosting space 1 in this way.

[0034] The flowing hot air in the solar hot air inlet pipe 2 forms an inward pressure on the outer plate surface of the one-way pressure-controlled base sealing plate 3, which generates an inward thrust of the one-way pressure-controlled base sealing plate 3, causing the one-way pressure-controlled base sealing plate 3 to open inward.

[0035] The principle of increasing the pressure of the solar hot air boosting space 1 is:

[0036] The hot air flows into the solar hot air pressurization space 1, causing the air quality and temperature in the space to increase. Under the condition that the space is closed and thermally insulated, the pressure in the space gradually increases.

[0037] The principle of closing the hot air channel of the one-way pressure-controlled base sealing plate 3 is:

[0038] The pressure in the solar hot air boosting space 1 gradually increases, and the inner plate surface pressure of the one-way pressure-controlled base sealing plate 3 gradually increases. A pressure difference is generated inside and outside the one-way pressure-controlled base sealing plate 3. The pressure of the one-way pressure-controlled base sealing plate 3, that is, the pressure of the solar hot air boosting space 1, is gradually increasing. When the inner plate surface pressure of the one-way pressure-controlled base sealing plate 3 is greater than the outer plate surface pressure, the one-way pressure-controlled base sealing plate 3 falls to the plumb bob position, which can close the passage of the flowing hot air in the solar hot air inlet pipe 2 to the solar hot air boosting space 1. At this time, the inner plate surface pressure of the one-way pressure-controlled base sealing plate 3 is the pressure of the combined effects of the weight of the one-way pressure-controlled base sealing plate 3, the increase in air mass and the temperature rise in the hot space, etc. The above-mentioned effects generate an outward thrust of the one-way pressure-controlled base sealing plate 3.

[0039] When the inner surface pressure of the one-way pressure-controlled base sealing plate 3 is greater than the outer surface pressure, the outward thrust of the one-way pressure-controlled base sealing plate 3 is greater than the inward thrust, and the one-way pressure-controlled base sealing plate 3 rotates outward around the one-way pressure-controlled base plate rotation pivot 5 and falls to the plumb bob position, thereby closing the channel of the flowing hot air in the solar hot air inlet pipe 2 to the solar hot air boosting space 1.

[0040] The principle of the pressure control effect of the one-way pressure control superimposed sealing plate 4 is:

[0041] Increasing the number of stacked plates of the one-way pressure control stacked sealing plate 4 can provide, supplement and increase the opening resistance of the channel. At the same time, increasing the number of stacked plates of the one-way pressure control stacked sealing plate 4 can provide, supplement and increase the closing thrust of the channel.

[0042] When the pressure of the solar hot air boosting space 1 is lower than the set range, the stacking plate setting of the one-way pressure control superimposed sealing plate 4 provides and supplements the opening resistance of the channel, thereby controlling the lower limit pressure range of the hot space. That is, only when the intake pressure is higher than the minimum pressure determined by the stacking plate setting, can the quality and temperature be increased in the solar hot air boosting space 1, thereby determining the lower limit pressure range of the hot space. Obviously, increasing the number of stacking plates of the one-way pressure control superimposed sealing plate 4 can increase the lower limit pressure range of the hot space. On the contrary, it decreases.

[0043] When the pressure of the solar hot air boosting space 1 is higher than the set range, the stacking plate setting of the one-way pressure control superimposed sealing plate 4 provides and supplements the shut-off thrust of the channel to control the pressure range of the hot space. Obviously, in different cases where the intake pressure is variable or constant, the stacking plate setting can play a role in controlling the pressure within a certain range. For example, under strong intake conditions, increasing the number of stacking plates can reduce the pressure when the hot space shuts off the channel. At this time, the hot air pressure in the hot space can be reduced, that is, the upper limit range of the hot space pressure can be controlled.

[0044] The principle of maintaining the set pressure of the solar hot air boosting space 1 is:

[0045] When the inner plate pressure of the one-way pressure-controlled base sealing plate 3 is greater than the maximum pressure of the outer plate, the hot air inlet channel is closed, resulting in the closure of the hot air space of the solar hot air boosting space 1. The solar hot air boosting space 1 is provided with thermal insulation to maintain the hot air pressure value within a set range.

[0046] The one-way closing setting mechanism of the one-way pressure-controlled base sealing plate 3 is:

[0047] The hot air inlet channel is a channel consisting of the outlet of the solar hot air inlet duct 2 and the opened one-way pressure-controlled base sealing plate 3, and has a maximum length and width. This channel is the hot air inlet formed by the south wall opening.

[0048] The length and width of the one-way pressure-controlled base sealing plate 3 are both set to be greater than the maximum length and width of the corresponding hot air inlet channel. It can be ensured that when the plate surface naturally falls to the plumb state, the plate surface can cover and seal the hot air inlet formed by the opening of the south wall. In this way, the one-way pressure-controlled base sealing plate 3 will not rotate outwardly toward the south wall surface to form a hot air inlet, but can only rotate inwardly toward the south wall to form a hot air inlet, forming an opening and closing with working conditions.

[0049] The one-way pressure-controlled base sealing plate 3 deviates from its plumb position and rotates inwardly and upwardly around the one-way pressure-controlled base rotating pivot 5 to open the hot air inlet channel, and rotates inwardly to the plumb direction to close the channel.

[0050] Under certain working conditions, the outer plate surface and the inner plate surface of the one-way pressure-controlled base sealing plate 3 can reach a pressure balance and maintain the inlet passage. The pressure on the inner plate surface will be greater than the pressure on the outer plate surface at a certain moment, and the one-way pressure-controlled base sealing plate 3 can rotate outward around the one-way pressure-controlled base plate rotation pivot 5 and fall to the plumb bob direction to close the hot air inlet passage.

[0051] The principle of automatic inflation and pressurization cycle after hot air is taken is:

[0052] Due to the closed space and thermal insulation, the solar hot air boosting space 1 can maintain the boosting pressure after the channel is closed. At this time, the hot air opening and closing outlet 8 is in a closed state. When taking the boosted hot air, the hot air opening and closing outlet 8 is opened, and the boosted hot air in the solar hot air boosting space 1 is depressurized and flows out.

[0053] At this time, the pressure on the inner and outer surfaces of the one-way pressure-controlled base sealing plate 3 gradually becomes unbalanced. The inner surface pressure of the one-way pressure-controlled base sealing plate 3 gradually decreases, resulting in a gradual decrease in the outward thrust of the one-way pressure-controlled base sealing plate 3 and a gradual increase in the inward thrust of the one-way pressure-controlled base sealing plate 3.

[0054] When the inward thrust on the one-way pressure-controlled base sealing plate 3 is sufficient to push the pressure-controlled plate to rotate inward around its rotation axis, the hot air inlet opens, and the hot air at outdoor atmospheric pressure enters the solar hot air boosting space 1 through the hot air channel.

[0055] Due to the closed space and thermal insulation, the mass and temperature of the air entering the solar hot air boosting space 1 increase, causing the pressure in the space to gradually increase again. In this way, a reverse pressure difference is generated inside and outside the one-way pressure-controlled base sealing plate 3. When the pressure on the inner plate surface of the one-way pressure-controlled base sealing plate 3 is greater than the pressure on the outer plate surface, it falls to the plumb bob position due to gravity, and the hot air channel can be closed again, starting the second pressure maintenance cycle.

[0056] The working process of the technical system of the present invention is:

[0057] The system process of the present invention includes sequential cyclic processes such as air intake pressurization, closed pressure maintenance, pressure relief and use, and cyclic air intake pressurization.

[0058] The intake boost process is:

[0059] Hot air equipment such as solar air collectors will continue to increase the quality and temperature of the enclosed space. Under the above working conditions, hot air enters the solar hot air boosting space 1 and increases the quality and temperature of the solar hot air boosting space 1.

[0060] The pressure in the solar hot air boosting space 1 gradually increases, and the inner plate surface pressure of the one-way pressure-controlled base sealing plate 3 gradually increases. A pressure difference is generated inside and outside the one-way pressure-controlled base sealing plate 3. When the inner plate surface pressure of the one-way pressure-controlled base sealing plate 3 is greater than the outer plate surface pressure, the thrust generated by the pressure difference and the force of the deadweight of the composite plate cause the one-way pressure-controlled base sealing plate 3 to fall to the plumb bob position, closing the hot air passage of the solar hot air inlet duct 2 to the solar hot air boosting space 1. At this time, the boosting process ends, and the pressure maintenance and use stages begin to be entered in sequence.

[0061] The closed pressure maintenance process is:

[0062] After the hot air passage is closed by the one-way pressure-controlled base sealing plate 3, the solar hot air boosting space 1 can maintain the boosted pressure due to the closed space and thermal insulation.

[0063] The pressure relief and use process is:

[0064] When the pressurized hot air is taken, the hot air opening and closing outlet 8 is opened, the pressurized hot air in the solar hot air pressurization space 1 is depressurized, and the pressurized hot air flows out.

[0065] The cycle of air intake and pressurization process is:

[0066] The pressure of the solar hot air boosting space 1 decreases as it is taken out, and the pressure on the inner plate surface of the hot air opening and closing outlet 8 gradually decreases. When it decreases to a level lower than the pressure on the outer plate surface of the hot air opening and closing outlet 8,

[0067] When the thrust of the hot air from the hot air equipment such as the solar air collector on the one-way pressure control base sealing plate 3 is sufficient to push the pressure control plate to rotate around the one-way pressure control base plate rotation pivot 5 into the solar hot air boosting space 1, a hot air inlet is formed. In this way, the hot air enters the solar hot air boosting space 1 through the channel formed by the one-way plate and the hot air inlet. The storage and use of the boosted hot air in the solar hot air boosting space 1 begins to circulate, and the intake boosting process is circulated again.

[0068] The process of the one-way pressure control and the pressure control of the sealing plate 4 is:

[0069] When the pressure of the solar hot air boosting space 1 is lower than the set range, the stacking plate setting of the one-way pressure control superimposed sealing plate 4 provides and supplements the opening resistance of the channel, thereby controlling the lower limit pressure range of the hot space. That is, only when the intake pressure is higher than the minimum pressure determined by the stacking plate setting, can the quality and temperature be increased in the solar hot air boosting space 1, thereby determining the lower limit pressure range of the hot space. Obviously, increasing the number of stacking plates of the one-way pressure control superimposed sealing plate 4 can increase the lower limit pressure range of the hot space. On the contrary, it decreases.

[0070] When the pressure of the solar hot air boosting space 1 is higher than the set range, the stacking plate setting of the one-way pressure control superimposed sealing plate 4 provides and supplements the shut-off thrust of the channel to control the pressure range of the hot space. Obviously, in different cases where the intake pressure is variable or constant, the stacking plate setting can play a role in controlling the pressure within a certain range. For example, under strong intake conditions, increasing the number of stacking plates can reduce the pressure when the hot space shuts off the channel. At this time, the hot air pressure in the hot space can be reduced, that is, the upper limit range of the hot space pressure can be controlled.

[0071] The technical system functions of the present invention are:

[0072] It can increase the quality and pressure of hot air, and passively control its pressure value within a certain range.

[0073] The technical and application characteristics of the present invention are:

[0074] The invention performs hot air boosting and pressure control in a completely natural way. The system design is simple, the structure is simple, the manufacturing is simple, and the cost is low. It operates in a completely natural, passive way and is low cost. Passive zero-energy mechanical pressure control replaces electrical or digital automatic control systems that consume power, have high investment and high maintenance costs.

[0075] The application scenarios of the technical system of the present invention are:

[0076] The present invention can improve the quality and pressure of solar hot air, and provide high-temperature and high-pressure solar hot air with pressure controlled within a certain range. It can be applied to some civil, industrial and agricultural production occasions that require high-pressure hot air. For example, heating, drying, using hot air power to propel and generate electricity, etc.

[0077] The application prospects of the technical system of the present invention are:

[0078] Passive energy and industrial systems have good energy, environmental protection, and material effects. This system belongs to the above-mentioned field technology and has good development and application prospects.

[0079] The technical system of composite equipment system and control system adopts passive control system, which is the secondary system of the overall composite technical system. Its control system adopts passive control secondary system, which can achieve zero energy consumption and optimal energy, environment and resource effects of the whole system, and has a large development space and application prospects.
