Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of grain coolers, and particularly relates to a condensate water recycling and secondary cooling device for a grain cooler. BACKGROUND

[0002] At present, the grain cooler is the mainstream technical equipment for grain bin ventilation cooling. During the operation of the equipment, the refrigerant sequentially undergoes compression, condensation, throttling and evaporation processes in the refrigeration cycle system to realize cooling and temperature reduction of the grain pile. In the condensation stage, the refrigerant is forcedly air-cooled heat exchanged with the outside air through the condenser to release heat to the environment, thereby realizing the transformation from the gaseous state to the liquid state. In the evaporation stage, the liquid refrigerant absorbs the heat of the grain pile to vaporize in the evaporator. A large amount of condensate water is generated in this process. In order to avoid waste caused by direct discharge of the condensate water, a recycling device is usually used to recycle and utilize the discharged condensate water for secondary cooling of the grain cooler to further improve the refrigeration efficiency of the grain cooler. However, the recycled condensate water is directly sprayed onto the external fins. In this treatment mode, the condensate water rapidly flows down due to the gravity and the heat exchange time with the fins only lasts for a few seconds. This instantaneous contact cannot sufficiently reduce the surface temperature of the fins, thereby limiting the heat exchange efficiency. Moreover, the condensate water is discharged before being completely vaporized, and the remaining cold energy is wasted, which cannot fully utilize the low temperature contained in the condensate water to improve the efficiency of the secondary cooling of the grain cooler. This is undoubtedly an unreasonable waste of energy and restricts the further improvement of the overall performance of the grain cooler. Therefore, the application provides a condensate water recycling and secondary cooling device for a grain cooler. SUMMARY

[0003] The technical problem to be solved by the application is to overcome the deficiencies of the prior art and provide a condensate water recycling and secondary cooling device for a grain cooler which can overcome the above problems or at least partially solve the above problems.

[0004] To solve the above technical problems, the basic idea of the technical scheme of the application is that a condensate water recycling and secondary cooling device for a grain cooler comprises a shunt shell, a first cavity and a second cavity which are mutually connected and arranged in a vertical direction from top to bottom in the interior of the shunt shell, a water inlet pipe which is fixedly connected to one side of the shunt shell and has an internal passage which is communicated with the first cavity, a plurality of water outlet pipes which are fixedly connected to the surface of the shunt shell in a horizontal equidistant distribution mode and have internal passages which are communicated with the second cavity, and a plurality of water guide brush strips which are arranged below the water outlet pipes and are tightly abutted with each other.

[0005] Preferably, the first cavity and the second cavity are in inverted L shape when viewed from top to bottom, wherein the depth of the second cavity is half of the depth of the first cavity, and the distance between the front and back walls of the second cavity is smaller than the distance between the front and back walls of the first cavity.

[0006] Preferably, the bottom wall of the first cavity is connected with a filter plate above the second cavity, and the transverse and longitudinal diameters of the filter plate are adapted to the corresponding transverse and longitudinal diameters of the first cavity.

[0007] Preferably, when the filter plate is connected with the bottom wall of the first cavity in a fit manner, a slot with the same size as the filter plate is formed in the top of the shunt shell, and the top of the shunt shell is provided with a detachable top plate, and the top of the filter plate is fixedly connected with a plurality of abutting rods which are in fit with the bottom of the top plate in a vertical direction.

[0008] Preferably, the shunt shell is provided with a connecting plate, the connecting plate comprises a vertical segment, an arc segment and a horizontal segment, the arc segment is fixedly connected between the vertical segment and the horizontal segment, so that the connecting plate forms an integral L-shaped structure, the connecting plate is fixedly connected to the shunt shell through the vertical segment, and the bottom of the horizontal segment is fixedly connected with a plurality of circular magnets which are horizontally distributed and equidistantly arranged.

[0009] Preferably, a pair of clamping blocks which are mirror-symmetrically arranged on the shunt shell are arranged below the connecting plate, the top section of the clamping block is in horizontal downward inclination structure, the bottom section of the clamping block is in horizontal upward inclination structure, and the side where the top section of the clamping block meets the bottom section is in pointed end shape.

[0010] Preferably, one end of the water guide brush strip is fixedly connected with a mounting rod, the surface of the shunt shell is fixedly connected with a mounting plate below the water outlet pipe, the surface of the mounting plate is provided with a mounting groove which is adapted to the size of the mounting rod, and the mounting rod is fixedly connected to the inner wall of the mounting groove.

[0011] Preferably, the other end of the water guide brush strip is fixedly connected with a counterweight rod, and a pulling mechanism is arranged between the surface of the counterweight rod and the surface of the shunt shell.

[0012] Preferably, the pulling mechanism comprises a pair of fixed plates which are fixedly connected to the shunt shell, a connecting shaft is rotatably arranged between the two fixed plates, a driving part is arranged on one side of one of the fixed plates and connected with one end of the connecting shaft, a plurality of equidistantly arranged winding wheels are fixedly connected to the connecting shaft, and a pull rope is fixedly connected between the surface of the winding wheel and the surface of the counterweight rod.

[0013] Preferably, when the winding wheel drives the pull rope to rotate forward, the pull rope drives the water guide brush strip to bend upward through the counterweight rod; and when the winding wheel drives the pull rope to rotate reversely, the pull rope drives the water guide brush strip to bend downward through the counterweight rod.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In this invention, a diversion shell, a water inlet pipe, a first chamber, a second chamber, and a water outlet pipe are designed to recycle and reuse the condensate discharged from the cooler for cooling treatment, thereby improving the cooling efficiency of the cooler. Meanwhile, a water guide brush strip is installed below the water outlet pipe to cooperate with the water outlet pipe. The water guide brush strip is curved downward and attached to the fins of the cooler. This design has two advantages. First, the condensate discharged from the water outlet pipe will first drip onto the surface of multiple water guide brush strips, and then slowly flow along the bristles to the fins. Compared with the method of condensate dripping directly onto the fins for instantaneous contact cooling, this design avoids the problem that the surface temperature of the fins cannot be fully reduced due to instantaneous contact, effectively breaking through the limitation of heat exchange efficiency under the traditional method. Second, the water guide brush strip makes the contact process between the condensate and the fins more gradual and sufficient, which can make full use of the low temperature contained in the condensate, allowing the fins to absorb cold for a longer period of time, thereby significantly improving the secondary cooling efficiency of the grain cooler and providing a strong guarantee for the efficient operation of the grain cooler. Furthermore, this invention also incorporates a drive unit, connecting shaft, winding wheel, pull rope, and counterweight bar. On one hand, when the cooler is working, it can precisely control the uniformity of the downward bending of the water guide brush strip, allowing condensate to flow evenly and fully across the fins, greatly improving cooling efficiency and effect. On the other hand, when the cooler is idle, the water guide brush strip can bend upward to prevent it from creeping due to prolonged contact with the fins, ensuring the water guiding function. At the same time, it prevents the water guide brush strip from occupying part of the space on the fin surface and obstructing airflow. It is worth mentioning that the upwardly bent water guide brush strip can cover the outer port of the water outlet pipe, preventing dust from entering and causing blockage and contamination of the condensate, ensuring unobstructed water outlet pipe and stable operation of the cooler.

DETAILED DESCRIPTION

[0017] The present application will be further described in detail below with reference to the accompanying drawings and examples, so that those skilled in the art can implement the present application according to the description.

[0018] It should be understood that the terms such as "have", "contain" and "include" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0019] In the description of the present application, the orientations or positional relationships indicated by the terms "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0020] Example one: refer to Figure 1 , Figure 2 and Figure 8 ​The utility model provides a kind of grain cooler condensate water recovery and secondary cooling device, including shunt shell 1, water inlet pipe 2, several water outlet pipes 3 and several water guide brush strips 4 arranged below water outlet pipe 3, wherein, each water guide brush strip 4 is mutually closely adhered, first cavity 11 and second cavity 12 that are mutually communicated are provided in the inside of shunt shell 1 from top to bottom along vertical direction, water inlet pipe 2 is fixedly connected in one side of shunt shell 1 and the inside passage of water inlet pipe 2 is communicated with first cavity 11, in the technical scheme, first, shunt shell 1 is fixed on the shell of cooler, and it is ensured that the side of shunt shell 1 with water outlet pipe 3 corresponds with the side of the fin of cooler shell, then, water inlet pipe 2 is connected with condensing pipe for drainage, at this time, the condensate water discharged in condensing pipe can enter first cavity 11 of shunt shell 1 by water inlet pipe 2, then flows into second cavity 12, when the water level of condensate water in second cavity 12 approaches the inner end of water outlet pipe 3, condensate water will flow out from the outer end of water outlet pipe 3, and drop on the fin of cooler shell, so that condensate water is used to cool cooler, and the refrigeration efficiency of cooler is improved.

[0021] Referring to Figure 6 The first cavity 11 and the second cavity 12 are inverted L-shaped when viewed from top to bottom, wherein the depth of the second cavity 12 is half of the depth of the first cavity 11, and the spacing between the front and rear walls of the second cavity 12 is smaller than the spacing between the front and rear walls of the first cavity 11. Based on this structural design, the volume of the second cavity 12 is smaller than the volume of the first cavity 11.

[0022] From the perspective of condensate water flow efficiency, since the volume of the second cavity 12 is small, the condensate water can fill the inner end of the water outlet pipe 3 in a shorter time in the second cavity 12. In this way, the condensate water can quickly flow out through the water outlet pipe 3 and drop on the fin of the cooler shell, achieving timely and effective cooling and greatly improving the utilization efficiency of the condensate water cooling capacity of the cooler and enhancing the cooling effect.

[0023] From the perspective of cold energy retention, the problem of cold energy loss due to long-term accumulation of condensate water in the shunt shell 1 is avoided. In traditional designs, if the volume of the cavity is too large, the condensate water will accumulate for a long time and exchange more heat with the surrounding environment, reducing the cold energy. However, the smaller volume of the second cavity 12 in the present design effectively reduces the residence time of the condensate water, ensuring that the condensate water acts on the fin of the cooler shell at a lower temperature and with higher cold energy, further optimizing the refrigeration performance of the cooler.

[0024] During the operation of the grain cooler, various impurities may be generated in the condensing pipe due to grain dust, equipment wear and other reasons. If these impurities directly enter the second cavity 12 and are discharged with the condensing water, not only will the water outlet pipe 3 be blocked, affecting the normal discharge of the condensing water, but also the impurities may adhere to the fins of the cooler shell, reducing the heat dissipation efficiency of the fins, and thus affecting the overall refrigeration performance of the cooler. Based on this problem, referring to Figure 3 and Figure 6 , the bottom wall of the first cavity 11 is connected with a filter plate 5 located above the second cavity 12. The transverse and longitudinal diameters of the filter plate 5 are adapted to the corresponding transverse and longitudinal diameters of the first cavity 11. This adaptive size design can ensure that the filter plate 5 completely covers the outlet area of the bottom wall of the first cavity 11. In this way, the condensing water flowing from the first cavity 11 into the second cavity 12 will be filtered by the filter plate 5 in full. This can effectively intercept impurities, particulate matter and tiny debris that may be carried in the condensing water, ensuring the purity of the condensing water and thus providing reliable protection for the stable operation of the cooler.

[0025] Referring to Figure 3 and Figure 6 , in order to clean and replace the filter plate 5 later, the filter plate 5 is connected with the bottom wall of the first cavity 11 in this embodiment. A slot 13 with the same size as the filter plate 5 is provided in the top of the shunt shell 1. The top of the shunt shell 1 is provided with a detachable top plate 14. The top of the filter plate 5 is fixedly connected with a plurality of abutting rods 51 in the vertical direction, which are in close contact with the bottom of the top plate 14. When the filter plate 5 needs to be cleaned or replaced, the top plate 14 is first removed. Since the abutting rods 51 are in close contact with the bottom of the top plate 14, after the top plate 14 is removed, the filter plate 5 loses the constraint of the top, and can be easily taken out through the slot 13. This design avoids the problem of difficult disassembly caused by the hidden installation position or complex fixing method of the filter plate 5, saving maintenance time and labor cost.

[0026] Referring to Figures 1-7To fix the shunt shell 1 on the shell of the cooling machine, a connecting plate 6 is arranged on the shunt shell 1, the connecting plate 6 comprises a vertical section 61, an arc-shaped section 62 and a horizontal section 63, the arc-shaped section 62 is fixedly connected between the vertical section 61 and the horizontal section 63, so that the connecting plate 6 forms an integral L-shaped structure, the connecting plate 6 is fixedly connected on the shunt shell 1 through the vertical section 61, and a plurality of circular magnets 64 horizontally distributed and equidistantly arranged are fixedly connected to the bottom of the horizontal section 63. In actual use scenarios, the shell of the cooling machine is generally made of iron. At this time, the circular magnets 64 on the bottom of the horizontal section 63 are only needed to be adsorbed on the top of the shell of the cooling machine, so that the shunt shell 1 can be easily fixed on the shell of the cooling machine for cooling operation. This fixing mode has many characteristics such as convenience, stability, economy, practicality and strong universality. In the fixing process, without the aid of complex tools and cumbersome installation steps, the operator only needs to approach the shunt shell 1 to the shell of the cooling machine, and let the circular magnets 64 on the bottom of the horizontal section 63 evenly and equidistantly distributed and the iron shell gently contact, and the fixing can be quickly completed by relying on the magnet adsorption force. Even in a small space and inconvenient environment, quick installation and disassembly can also be easily realized, which greatly saves the installation time and labor cost, improves the overall work efficiency, and at the same time, is stable and reliable. When the cooling machine runs and vibrates, the shunt shell 1 will not easily loosen or shift, and can continuously and stably play the cooling function, providing a solid guarantee for the normal operation of the cooling machine. From the cost point of view, the circular magnet 64 is low in price, the material for making the connecting plate 6 is common, and the overall manufacturing cost is not high, which can effectively reduce the production and use cost of enterprises. Moreover, since most of the shells of the cooling machines are made of iron, this fixing mode based on the magnet adsorption has wide applicability and can be applied to many different types and specifications of cooling machines. Without the need to design a complex fixing structure for each type of cooling machine, the universality and market competitiveness of the product are greatly improved.

[0027] With reference to Figure 9 A pair of clamping blocks 7 symmetrically arranged on the shunt shell 1 is arranged below the connecting plate 6, the top section of the clamping block 7 is horizontally inclined downward, the bottom section is horizontally inclined upward, and the side where the top section and the bottom section of the clamping block 7 meet is in a pointed end shape. When the horizontal section 63 is fixed to the top of the shell of the cooling machine through the circular magnet 64, the clamping block 7 can be clamped into the fin rack of the shell of the cooling machine. In this way, the shunt shell 1 can be conveniently supported before being fixed, and the stability of the connection with the shell of the cooling machine can be enhanced after being fixed in cooperation with the connecting plate 6.

[0028] Embodiment two: with reference to Figures 1-4On the basis of the above embodiment one, further comprising several water guide brush strips 4 arranged below the water outlet pipe 3, each water guide brush strip 4 is closely attached to each other, one end of the water guide brush strip 4 is fixedly connected with a mounting rod 41, the surface of the shunt shell 1 is fixedly connected with a mounting plate 42 located below the water outlet pipe 3, the surface of the mounting plate 42 is provided with a mounting groove 43 matched with the mounting rod 41 in size, the mounting rod 41 is fixedly connected on the inner wall of the mounting groove 43, when the shunt shell 1 is fixed with the top of the cooling machine shell through the connecting plate 6, the water guide brush strip 4 arranged below the water outlet pipe 3 is bent downward at 45 degrees and closely attached to the fins of the cooling machine shell, this design, firstly, the condensed water discharged from the water outlet pipe 3 will first drop on the surface of the plurality of water guide brush strips 4, then slowly flow along the bristles to the fins, compared with the way that the condensed water directly drops on the fins and instantaneously contacts cooling, this design can avoid that the surface temperature of the fins cannot be sufficiently reduced due to instantaneous contact, thereby effectively breaking through the limitation of heat exchange efficiency in the traditional way, secondly, the water guide brush strip 4 makes the contact process of the condensed water and the fins more gentle and sufficient, can fully utilize the low temperature contained in the condensed water, makes the fins absorb cold for a longer time, thereby significantly improves the secondary cooling efficiency of the grain cooler, provides a powerful guarantee for the efficient operation of the grain cooler, when the condensed water evaporates or cools on the surface of the fins, the inlet air temperature flowing through the fins will be reduced at the same time, thereby realizing the indirect precooling effect on the inlet air, the benefits of this integration are that, on the basis of the cooling effect of the water guide brush strip 4 on the fins, further expands the influence of this design on the inlet air temperature, makes the whole cooling process more efficient.

[0029] Embodiment three: refer to Figures 1-9 On the basis of the above embodiment two, the other end of the water guide brush strip 4 is fixedly connected with a counterweight rod 44, a pulling mechanism is arranged between the surface of the counterweight rod 44 and the surface of the shunt shell 1, the pulling mechanism comprises a pair of fixed plates 8 fixedly connected on the shunt shell 1, a connecting shaft 81 is rotatably arranged between the two fixed plates 8, a driving part 82 is mounted on one side of one of the fixed plates 8 and connected with one end of the connecting shaft 81, a plurality of equally spaced winding wheels 83 are fixedly connected on the connecting shaft 81, a pull rope 84 is fixedly connected between the surface of the winding wheel 83 and the surface of the counterweight rod 44.

[0030] In the technical scheme, when the condensate water recovered in the shunt shell 1 is used to cool the cooling machine shell fins, the driving part 82 driven by the servo motor is started to drive the connecting shaft 81 to rotate, and then the winding wheel 83 drives the pull rope 84 to rotate in the opposite direction, and the pull rope 84 bends the plurality of water guide brush strips 4 downward through the counterweight rod 44, and the bending degree is consistent. This consistency ensures that the condensate water can flow uniformly along the water guide brush strip 4 to the cooling machine shell fins. If the bending degree of the water guide brush strip 4 is different, the condensate water will be unevenly distributed, and some fins will be over-cooled and some will be under-cooled. However, the design effectively avoids this problem, realizes uniform cooling of the fins, and improves the overall cooling effect. Moreover, the consistent bending of the water guide brush strip 4 also enables the condensate water to flow slowly and orderly along the bristles. Compared to the rapid and disordered dripping of the condensate water when the bending degree of the water guide brush strip 4 is uneven, this design greatly prolongs the contact time of the condensate water and the fins, enabling the fins to more fully absorb the cold energy of the condensate water, further improving the cooling efficiency and enhancing the cooling effect on the cooling machine shell, which helps to improve the operating performance of the entire grain cooler.

[0031] When the cooling machine is not in use, the driving part 82 driven by the servo motor is started to drive the winding wheel 83 on the connecting shaft 81 to make the pull rope 84 rotate in the positive direction, and the pull rope 84 drives the water guide brush strip 4 to bend upward through the counterweight rod 44. This can prevent the water guide brush strip 4 from always sticking to the fins. If the water guide brush strip 4 sticks to the fins for a long time, under the continuous action of its own gravity and the possible reaction force of the fins, the water guide brush strip 4 will creep, that is, it will undergo irreversible plastic deformation. This deformation will cause the water guide brush strip 4 to be unable to restore to its original shape and bending degree, thereby affecting the accuracy and uniformity of subsequent condensate water guidance. In addition, the water guide brush strip 4 always adheres to the fins, which will occupy part of the space on the surface of the fins and hinder the normal circulation of air. This will cause the air around the fins to flow poorly, reducing the heat exchange efficiency and requiring a longer time for the cooling machine to reach the expected cooling effect when it is started again.

[0032] At the same time, the upwardly bent water guide brush strip 4 also shields the outer port of the water outlet pipe 3. When the cooling machine is not in use, the water outlet pipe 3 is in an idle state and is prone to have dust enter its interior. Dust accumulation may block the water outlet pipe 3, affecting the subsequent condensate water discharge efficiency, and even possibly contaminating the water quality of the condensate water. The design effectively prevents dust from entering the water outlet pipe 3 through the shielding of the water guide brush strip 4, ensuring the smoothness of the water outlet pipe 3 and the normal discharge of the condensate water, and ensuring the stable operation of the grain cooler.

[0033] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any skilled person in the art can make some changes or modifications to the above-mentioned technical content with the prompt as equivalent embodiments of equivalent changes without departing from the technical solution of the present application. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, which does not depart from the technical solution of the present application, still belongs to the scope of the present application.
