Description

Technical Field

[0001] The utility model relates to the technical field of seed drying and dust removal, in particular to a dust collection system. Background Art

[0002] In the agricultural production and seed processing industries, seed drying systems play a vital role in effectively removing excess moisture from seeds to ensure that seeds maintain good vitality and quality during storage, transportation and sowing. However, the dust and impurities generated during seed drying not only affect the drying efficiency, but may also pose a threat to the environment and the health of operators.

[0003] To this end, the existing seed drying air flow circulation system is usually equipped with an ash collecting chamber. The airflow with dust and waste heat after the seeds are dried in the drying tower is introduced into the ash collecting chamber, and the dust is filtered and deposited in the waste heat airflow. The clean airflow with heat and after filtering is transported to the environment where the heat pump unit is located, thereby circulating air energy and ensuring a clean working environment that meets environmental protection and safety standards.

[0004] In the existing seed drying and ash collection system, the heat pump unit provides a constant heat flow to the drying tower to ensure uniform drying of the seeds in the drying tower. However, due to the amount of seeds to be dried in the drying tower and the circulation demand of hot air, the air outlet of the drying tower is not able to constantly output the waste heat air flow carrying dust, and the ash collection chamber is often in a closed state. Therefore, the airflow in the ash collection chamber to the dust removal bag will not be stable, which will cause unstable air pressure in the chamber. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figure 1 As shown, the utility model provides an ash collection system, including an ash collection chamber 10 and a box chamber 20 installed above the ash collection chamber 10. In the specific application and actual production process of the utility model, the ash collection chamber 10 is specifically a house building, and the box chamber 20 is a box-type building with an insulation structure.

[0032] Among them, a partition 30 is arranged between the ash collecting chamber 10 and the box chamber 20, that is, the floor between the buildings, and air holes 50 are distributed on the partition 30, that is, a plurality of circular openings evenly distributed are opened on the floor, and the circular openings connect the ash collecting chamber 10 and the box chamber 20. A dust removal bag 40 is suspended inside the box chamber 20, and the bottom of the dust removal bag 40 is connected to the air holes 50, and the top of the dust removal bag 40, and the air holes 50 send the dust-laden air in the ash collecting chamber 10 into the dust removal bag 40; the side wall of the ash collecting chamber 10 is provided with an air inlet 70, and the ash collecting chamber 10 is provided with an active air supply device 60, and the active air supply device 60 is used to replenish air into the ash collecting chamber 10.

[0033] An air inlet 70 connected to the air outlet of the drying tower is provided on the side wall of the ash collecting chamber 10 close to the seed drying tower. After the seeds are dried in the drying tower, the residual hot air flow carrying dust enters the ash collecting chamber 10 through the air inlet 70 .

[0034] In the existing seed drying and ash collection system, the heat flow provided by the heat pump unit to the drying tower is constant to ensure uniform drying of the seeds in the drying tower. However, due to the influence of the amount of seeds to be dried in the drying tower and the circulation demand of the hot air, the air outlet of the drying tower is not able to constantly output the waste heat air flow carrying dust, and the ash collection chamber 10 is often in a closed state. Therefore, the airflow in the ash collection chamber 10 to the dust removal bag 40 will not be stable, which will cause the air pressure in the box chamber 20 to be unstable.

[0035] To this end, the present invention provides an active air replenishing device 60 to automatically replenish air in the ash collecting chamber 10 when the air pressure in the ash collecting chamber 10 does not meet the standard, thereby improving the residual heat air flow to stably pass through the dust removal bag 40.

[0036] Of course, the detection of the air pressure in the ash collecting chamber 10 by a sensor is an inevitable choice of this solution. The technology of air pressure detection is also relatively mature, and this utility model does not involve it too much. The active air supply device 60 can include an air pressure detection and control module in the ash collecting chamber 10, so as to supply air to the ash collecting chamber 10. The most common method is to directly pump air into the ash collecting chamber 10 through a pipeline with an air pump.

[0037] The utility model places the heat pump unit in the box chamber 20 when carrying out the air energy heat circulation drying tower seed drying system based on the heat pump unit. The box chamber 20 can provide a clean and dry air flow with residual heat after filtering by the heat pump unit, and the pressure in the ash collecting chamber 10 is replenished through an active air replenishing device. On the one hand, it can ensure that the airflow entering the dust bag 40 can ensure the filtering effect of the dust bag 40, and on the other hand, it can ensure the constant pressure of the airflow in the box chamber 20 after filtration.

[0038] In order to more clearly illustrate the working principle of the above-mentioned active air supply device 60, the utility model provides a specific implementation of the active air supply device 60, whose purpose is to pump air into the ash collecting chamber 10, which is obviously cleaner air, that is, to pump air from the external air environment of the ash collecting chamber 10, so the air pumping pipe can be set on the cavity wall of the ash collecting chamber 10, but the ash collecting chamber 10 is used for dust collection, and it is necessary to connect the inner wall of the ash collecting chamber 10 with the environment inside the ash collecting chamber 10 if it is set on the inner wall of the ash collecting chamber 10, otherwise dust will be easily deposited in the device, causing equipment failure.

[0039] To this end, the active air supply device 60 provided by the utility model includes a main pipeline 61 arranged in the interlayer 30, which is laid when the interlayer 30 is constructed, and a branch pipe 62 connected to the main pipeline 61. One end of the main pipeline 61 extends to the outside of the ash collecting chamber 10 to connect with the outside air. A check valve 63 is arranged inside the end of the main pipeline 61 connected to the outside air to prevent the air in the box chamber 20 from escaping through the main pipeline 61. An air pump is connected to the main pipeline 61, and the end of the branch pipe 62 away from the main pipeline 61 is connected to the air hole 50. The pipeline for pumping air supply is arranged in the interlayer 30, and the air in the box chamber 20 is all filtered by the dust bag 40, and its cleanliness is obviously greater than that inside the ash collecting chamber 10.

[0040] In the present invention, the air hole 50 is used to directly replenish air into the box chamber 20, but it is necessary to realize the drainage effect through the dust removal bag 40, that is, the airflow in the dust collection chamber 10 is attracted into the dust removal bag 40. Then, the dust removal bag 40 includes an inner bag 41 and an outer bag 42 arranged outside the inner bag 41. The top of the inner bag 41 is sealed, and the top inner wall of the outer bag 42 does not contact the top of the inner bag 41 to form an opening 43.

[0041] The air hole 50 is formed by a pipe arranged on the partition layer 30, and the pipe is connected to the dust collecting chamber 10 and the dust removal bag 40;

[0042] The branch pipe 62 is connected to the pipeline, and the airflow pumped by the air pump enters the pipeline through the branch pipe 62 , and the direction of the airflow generated by the branch pipe 62 is toward the top of the dust removal bag 40 .

[0043] The bottom of the inner bag 41 is connected to the inner through pipe 51 , and the bottom of the outer bag 42 is sealedly connected to the outer through pipe 52 .

[0044] The end of the branch pipe 62 in the utility model away from the main pipe 61 is connected to the outer wall of the outer through pipe 52 , and the branch pipe 62 communicates with the cavity between the inner wall of the outer through pipe 52 and the outer wall of the inner through pipe 51 .

[0045] That is, in specific operation, when it is necessary to maintain the air pressure in the chamber 20 stable, the air pump transports air to each branch pipe 62 through the main pipe 61, the air in the branch pipe 62 is transported into the cavity, and the air in the cavity is transported to the cavity formed between the outer wall of the inner bag 41 and the inner wall of the outer bag 42. The purpose is to supplement the air pressure in the chamber 20. The gas in the outer bag 42 will attract the inner bag 41 through the airflow effect, so that the gas in the ash collecting chamber 10 enters the inner bag 41.

[0046] This can also prevent the dust deposited in the ash collecting chamber 10 from being raised by directly supplying air into the ash collecting chamber 10 .

[0047] To further illustrate, the mesh number of the outer bag 42 in the present invention is smaller than the mesh number of the inner bag 41 , that is, the filtering effect of the outer bag 42 is lower than the filtering effect of the inner bag 41 .

[0048] The main purpose is that the top of the airflow channel formed between the inner bag 41 and the outer bag 42 is open to form an opening 43, and a unidirectional airflow can be formed in the airflow channel, that is, upward along the length direction of the outer bag 42.

[0049] At this time, the air pump has started to work, and air is delivered to the air flow channel through the branch pipe 62 to achieve pressure replenishment in the chamber 20 to maintain the stability of the air pressure delivered to the chamber 20 after being filtered by the inner bag 41.

[0050] When not in operation, the structure of the inner bag 41 and the outer bag 42 can also achieve secondary filtration of the air flow entering the inner bag 41 .

[0051] Furthermore, the air pump in the utility model can also provide a pulsed air flow so that the pulsed air flow entering the air flow channel can exert a pulsed effect on the surface of the inner bag 41 to prevent dust from accumulating on the inner surface of the inner bag 41 .

[0052] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
