Description

Technical Field

[0001] This utility model relates to the field of grain dryer technology, and in particular to a convenient impurity removal device for a crossflow grain dryer. Background Technology

[0002] As is well known, the drying layer of a grain dryer typically has several air inlet and exhaust channels. The grain channel is located between the air inlet and exhaust channels, and the air ducts and grain channel are separated by a mesh panel. When the dryer is working, hot air enters from the air inlet channel, passes through the grain channel, and reaches the exhaust channel. During this process, the hot air carries away the moisture and some impurities from the grain.

[0003] In a typical dryer, the entire inlet and the latter half of the exhaust duct are areas with strong airflow, where impurities are quickly blown away and do not accumulate. However, in the first half of the exhaust duct, due to airflow diversion and other factors, the airflow is weaker, causing various impurities to accumulate and affecting the dryer's efficiency. Furthermore, due to the structure of the drying layer, cleaning impurities within the exhaust duct is quite difficult. Utility Model Content

[0004] The present invention aims to provide a convenient impurity removal device for a crossflow grain dryer to overcome or at least partially solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this utility model is specifically implemented as follows:

[0006] This utility model provides a convenient impurity removal device for a crossflow grain dryer, including a lower body. The lower body has an opening for impurity removal, and an impurity removal baffle is provided on the lower side of the opening. The lower side of the impurity removal baffle is provided with a limiting groove, which is welded and fixed to the top of the inner side of the lower body. A pull rod limiting block is also fixedly connected to the lower side of the impurity removal baffle, and the pull rod limiting block is fixedly connected to the pull rod. The pull rod passes longitudinally through a front partition, a rear partition, and multiple inner partitions, and the front end of the pull rod passes through the front partition and is connected to a rubber handle. The front partition and the rear partition are respectively fixed to the front end and the rear end of the lower body, and the inner partition is fixed between two adjacent openings.

[0007] As a further embodiment of this utility model, multiple discharge baffles, pull rod limiting blocks, and openings are provided, and the multiple discharge baffles, pull rod limiting blocks, and openings correspond one-to-one.

[0008] As a further embodiment of this utility model, the front end of the pull rod is provided with an external thread, and the front end of the pull rod is engaged with the rubber handle through the external thread.

[0009] As a further embodiment of this utility model, the lower body is fixedly installed on the lower side of the exhaust duct of the dryer and in close contact with the bottom end of the exhaust duct.

[0010] This utility model provides a convenient impurity removal device for a crossflow grain dryer. The beneficial effects are: after drying, by opening the impurity removal device, impurities in the exhaust channel can be quickly discharged; and during drying, closing the impurity removal device will not affect the normal operation of the drying section.

[0021] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0022] See Figure 1-5 This utility model provides a convenient impurity removal device for a crossflow grain dryer, including a lower body 1. The lower body 1 has an opening for impurity removal, and an impurity removal baffle 5 is provided on the lower side of the opening. The lower side of the impurity removal baffle 5 is provided with a limiting groove 8, which is welded and fixed to the top of the inner side of the lower body 1. A pull rod limiting block 7 is also fixedly connected to the lower side of the impurity removal baffle 5, and the pull rod limiting block 7 is fixedly connected to the pull rod 6. The pull rod 6 passes longitudinally through the front partition 2, the rear partition 3 and multiple inner partitions 4, and the front end of the pull rod 6 passes through the front partition 2 and is connected to a rubber handle 9. The front partition 2 and the rear partition 3 are respectively fixed to the front end and the rear end of the lower body 1, and the inner partitions 4 are fixed between two adjacent openings.

[0023] Multiple discharge baffles 5, pull rod limit blocks 7, and openings are provided, and the multiple discharge baffles 5, pull rod limit blocks 7, and openings correspond one-to-one.

[0024] The front end of the pull rod 6 is provided with an external thread, and the front end of the pull rod 6 is engaged with the rubber handle 9 through the external thread.

[0025] The lower body 1 is fixedly installed on the lower side of the exhaust duct 13 of the dryer and is in close contact with the bottom end of the exhaust duct 13.

[0026] During use, when the grain dryer (14) is undergoing prolonged drying, the impurity removal device needs to be closed by pushing the rubber handle 9 inward to the limit position. At this time, the bottom of the exhaust channel 13 is closed, and light impurities are generally discharged with the airflow, while heavy impurities accumulate at the bottom of the exhaust channel 13. This also ensures the stability of the grain drying rate and prevents secondary contamination of the grain (14). After prolonged grain drying, a large amount of impurities accumulate in the exhaust channel 13. Simply pull the rubber handle 9 outward to the limit position. The fan will then start, and some light impurities will be discharged through the airflow, while heavy impurities will be easily discharged through the square outlet on the upper side of the device. This device effectively solves the problems of difficult-to-clean impurity accumulation in the exhaust channel 13 of the drying section of ordinary cross-flow grain dryers, reducing grain drying efficiency and increasing the risk of fire.

[0027] See Figure 6 During the operation of the dryer, grain 14 enters the drying layer from the upper tempering layer under the influence of gravity. After drying, it falls into the lower circulation layer and is lifted by the elevator belt to repeat the above process. In the drying layer, hot air enters from the air inlet channel 12, passes through the grain channel 11, and finally exits from the exhaust channel 13. In this process, some moisture from the grain 14 is carried away, and some impurities are also carried into the exhaust channel. Because the airflow is relatively weak in the first half of the exhaust channel 13, impurities accumulate here. Ordinary dryers, due to the enclosed structure of the exhaust channel 13, do not have the ability to handle impurities in the exhaust channel 13 of the drying section.

[0028] See Figure 7 When the dryer is in operation, push the rubber handle 9 of the convenient impurity removal device into the drying section of the dryer to the limit position to close the impurity removal port. Because hot air continuously enters the air inlet channel 12 at a relatively high speed, it blows small impurities such as twigs from the grain 14 in the grain channel 11 into the exhaust channel 13. Most of the light impurities will be discharged from the exhaust channel 13, while a small portion of heavy impurities will deposit at the bottom of the exhaust channel 13.

[0029] See Figure 8 When the grain 14 is finished drying and needs cleaning, pull the rubber handle 9 of the convenient impurity removal device outward to the limit position to open the impurity removal port. Then, start the fan; some of the lightweight branches accumulated in the exhaust duct 13 will be discharged through the fan; heavy impurities such as small stones will fall into the auger due to gravity and then be lifted into the machine's overall impurity removal system for thorough cleaning. This solves the problem of difficult-to-clean impurities in the exhaust duct 13 of ordinary dryers.

[0030] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
