Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology in feed processing, and in particular relates to a dust removal and screening device for feed processing. Background Technology

[0002] Feed processing refers to the process of transforming raw materials into feed suitable for animal husbandry through a series of physical and chemical treatments. This process includes steps such as washing, crushing, batching, mixing, pelleting, drying, and packaging, aiming to improve the nutritional value, palatability, and digestibility of the feed.

[0003] Before feed processing and packaging, dust in the feed is usually treated to reduce its content and prevent it from affecting the animal husbandry environment. In current technology, dust is mostly treated by negative pressure adsorption. The dust cleaning process can only purify the dust and cannot remove fine particles at the same time. Fine particles will also form new dust due to compression during the later transportation process. Therefore, fine particles need to be screened at the same time during the dust treatment process. Utility Model Content

[0004] This utility model provides a dust removal and screening device for feed processing, which aims to solve the problem that existing dust treatment processes cannot screen out small particles at the same time as dust treatment because small particles will regenerate into new dust due to compression during the later transportation process.

[0005] This utility model is implemented as follows: a dust removal and screening device for feed processing, comprising:

[0006] Several processing chambers are connected in series. Each processing chamber includes a base and an outer cover, with an inlet and an outlet respectively on the base and the outer cover.

[0007] The processing chamber is further provided with a first partition and a second partition. The part between the first partition and the second partition is a flow channel. The second partition and the outer cover form a negative pressure chamber. The bottom support and the first partition form a collection chamber.

[0008] Preferably, the first partition has a first inclined surface and a second inclined surface, and the angle between the first inclined surface and the horizontal plane is greater than the angle between the second inclined surface and the horizontal plane.

[0009] Preferably, both the first and second inclined surfaces are provided with sieve holes, so that as the feed slides along the surface of the first partition, loose and tiny feed particles will fall from the sieve holes into the collection chamber.

[0010] Preferably, the second partition is provided with air holes, and the smoke and dust generated during the sliding process of the feed will pass through the air holes and enter the negative pressure chamber under the negative pressure effect.

[0011] Preferably, the processing chamber is further provided with a discharge device, which includes a side discharge port, a first guide slope and a second guide slope disposed on the outer cover. The first guide slope is connected to the second guide slope, and the end of the inclined surface of the second guide slope is the side discharge port.

[0012] Preferably, the number of processing chambers is not less than three sets, with two adjacent sets of processing chambers interconnected, and the discharge port of one set of processing chambers connected to the inlet of another set of processing chambers.

[0013] Preferably, the plurality of processing chambers are stacked to form a processing module. The processing module is provided with a discharge pipe on one side and a vacuum pipe on the other side. The vacuum pipe is connected to the negative pressure chamber of different processing chambers, and the discharge pipe is connected to the discharge device of different processing chambers.

[0014] Preferably, the discharge pipe includes a culvert and a discharge guide rail, the discharge guide rail is located at the end of the culvert, and the culvert is provided with a number of collection ports, which are connected to the side discharge ports of different discharge devices.

[0015] Compared with the prior art, the embodiments of this application have the following main advantages:

[0016] In the feed processing dust removal and screening device provided by this utility model, after the material enters the processing module, it moves along the flow channel under its own weight. During the reversing motion, the material will separate and disperse, allowing some low-weight dust to fall off the material during the movement. The first and second partitions work together with the negative pressure chamber to screen and recover the material during the falling process. Small particles of material enter the collection chamber under the screening of the first partition, while dust and similar materials are attracted to the negative pressure chamber and then drawn out. Through the combination, the treatment of small particles is completed in the dust screening process, realizing the purpose of multiple screening of materials. Attached Figure Description

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] This utility model provides a dust removal and screening device for feed processing, such as... Figures 1-6 As shown, the feed processing dust removal and screening device includes:

[0030] The first processing chamber 110, the second processing chamber 120, and the third processing chamber 130 have basically the same structure.

[0031] Taking the first processing chamber 110 as an example, the first processing chamber 110 includes a base 101 and an outer cover 102. The outer cover 102 is provided with a feed inlet 103, and the base 101 is provided with a discharge outlet 104. The feed inlets 103 on the second processing chamber 120 and the third processing chamber 130 are respectively connected to the discharge outlets 104 of the other processing chambers, and are connected in series to form an integral flow channel.

[0032] The first processing chamber 110 is also provided with a first partition 140 and a second partition 150. The portion between the first partition 140 and the second partition 150 is a flow channel. The second partition 150 and the outer cover 102 form a negative pressure chamber. The bottom support 101 and the first partition 140 form a collection chamber. The second processing chamber 120 and the third processing chamber 130 are also provided with negative pressure chambers and collection chambers.

[0033] The first processing chamber 110, the second processing chamber 120 and the third processing chamber 130 are also provided with a discharge pipe 200 and a vacuum pipe 300 on the outside. The discharge pipe 200 is connected to the collection chamber and the vacuum pipe 300 is connected to the negative pressure chamber.

[0034] The first processing chamber 110, the second processing chamber 120 and the third processing chamber 130 form a processing module. After the material enters the equipment, it will move along the flow channel under its own weight. During the reversing motion, the material will separate and disperse, allowing some low-weight dust to fall off the material during the movement. The first partition 140 and the second partition 150 work together with the negative pressure chamber to screen and recover the material during the falling process, thereby improving the feed screening effect.

[0035] The first partition 140 is used to screen small particles of material. These particles are not easily attracted by negative pressure, while dust and similar materials are attracted to the negative pressure chamber and then drawn out. By combining these methods, the fine particles are processed during the dust screening process, achieving multiple screening of materials.

[0036] In a preferred embodiment of this invention, the first partition 140 is provided with a first inclined plane and a second inclined plane. The angle between the first inclined plane and the horizontal plane is greater than the angle between the second inclined plane and the horizontal plane. The reason why the first inclined plane is steeper than the second inclined plane is to help the material obtain greater acceleration and reduce the occurrence of material stagnation in the flat section.

[0037] Both the first and second inclined surfaces are provided with sieve holes. As the feed slides along the surface of the first partition 140, loose and tiny feed particles will fall from the sieve holes into the collection chamber. Here, the first and second inclined surfaces are equivalent to a screening structure, allowing small particles to be separated from the material under their own weight, thereby improving the uniformity of the material.

[0038] In this embodiment, the first partition 140 can be assembled on the base 101 in a detachable manner, and materials of other particle sizes can be replaced as needed when switching products.

[0039] In a preferred embodiment of this invention, the second partition 150 is provided with air holes. When the feed slides down, the smoke and dust generated will pass through the air holes and reach the negative pressure chamber under the negative pressure effect. The negative pressure chamber is connected to the vacuum pipeline 300 through a pipeline, and the vacuum pipeline 300 is connected to an external vacuum device.

[0040] As a preferred embodiment of this example, the first processing chamber 110 is further provided with a discharge device. The discharge device includes a side discharge port 105, a first guide slope 161, and a second guide slope 162 disposed on the outer cover 102. The first guide slope 161 is connected to the second guide slope 162, and the end of the inclined surface of the second guide slope 162 is the side discharge port 105.

[0041] In this embodiment, the connection between the first guide slope 161 and the second guide slope 162 mainly helps to guide the sieved small material particles to avoid material accumulation in the collection bin, while the side discharge port 105 is directly opened on the side wall of the outer cover 102, and unqualified products are sent out from the side discharge port 105.

[0042] In a further preferred embodiment of this utility model, the second processing chamber 120 and the third processing chamber 130 also adopt a discharge device. It should be noted that in order to allow the discharge pipe 200 to be located on the same end face of the processing module, the discharge device inside the second processing chamber 120 is set in the opposite direction to the first processing chamber 110 and the third processing chamber 130. When the number of processing chambers is more than three, they are connected in series in the same way, and the discharge devices in adjacent processing chambers are set in opposite directions.

[0043] In a preferred embodiment of this invention, the discharge pipe 200 includes a culvert 210 and a discharge guide rail 220. The discharge guide rail 220 is disposed at the end of the culvert 210. The culvert 210 is provided with a plurality of collection ports, which are connected to the side discharge ports 105 of different discharge devices.

[0044] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art can still combine, add, delete, or otherwise adjust the features of the various embodiments of this utility model according to the circumstances without conflict or creative effort, thereby obtaining different technical solutions that do not fundamentally depart from the concept of this utility model.
