Description

TECHNICAL FIELD

[0001] The utility model relates to pesticide preparation equipment technical field, concretely is a kind of powder pesticide mixing device. BACKGROUND

[0002] The original drug of pesticide generally cannot be directly used, and must be processed and prepared into various types of preparations to be used. The type of preparation is called dosage form, and commercial pesticides are sold to users in the form of a certain dosage form. More than ten dosage forms are used in China, including emulsifiable concentrate, suspension concentrate, wettable powder, powder, granule, water agent, bait, mother liquor and mother powder. Among them, powder has the longest history. Powder is popular among the masses in arid areas or mountainous areas where water is difficult to obtain, because it is convenient to use, does not require water, can be directly sprayed on crops with a simple powder sprayer, has high efficiency, has small adhesion on crops, has less residue and is not easy to cause drug damage. In addition to being directly used for spraying, it can also be used for seed dressing, soil treatment and preparation of bait granules to prevent and control diseases, insects and rodents. The disadvantage of powder is that during use, particles with a diameter less than 10 microns are easy to drift and cause environmental pollution, affecting people's health. Similarly, during processing, there is a lot of dust, which has a greater impact on the health of operators. Therefore, how to avoid dust drift during production has become an important issue.

[0003] CN212142411U discloses a dust collection and filtration device for powder pesticide mixing tank, which is installed on the mixing tank body and includes a dust collection hole.

A plurality of dust collection and filtration components are arranged on one side of the filtration chamber, and the dust collection and filtration components are connected to the air extraction chamber. An air extraction pipeline is arranged on the air extraction chamber, and the air extraction pipeline is connected to an air extractor. The above-mentioned device can prevent pesticide dust from diffusing out of the feeding hole during pesticide mixing and adding. However, using this filtration device will adhere to a part of the pesticide powder, which increases the mechanical loss of the pesticide during production. UTILITY MODEL CONTENT

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Embodiment 1

[0022] Reference Figure 1 、 2 The powder pesticide mixing device comprises a primary stirring tank 1 and a secondary stirring tank 2 connected in sequence, and further comprises a recovery unit 3; the primary stirring tank 1 is provided with a feed inlet 101; the recovery unit 3 is used for extracting pesticide powder diffused from the feed inlet 101 and inputting the pesticide powder into the primary stirring tank 1 and the secondary stirring tank 2 again.

[0023] In actual application, raw materials such as raw pesticides, fillers and surfactants are input from the feed inlet 101 of the primary stirring tank 1, the raw materials are preliminarily mixed in the primary stirring tank 1, and then further mixed in the secondary stirring tank 2, and the recovery unit 3 collects fine pesticide diffused to the environment and inputs the fine pesticide into the primary stirring tank 1 and the secondary stirring tank 2 again, so as to solve the pollution problem caused by the fine pesticide dust diffused to the environment, and ensure the accurate degree of pesticide proportioning and reduce the loss.

[0024] The embodiment has the following advantages: the two-stage stirring can more fully mix the pesticide, the primary stirring tank 1 preliminarily mixes the raw materials, and then the secondary stirring tank 2 further mixes the raw materials, so as to improve the quality of the powder pesticide produced subsequently; and the recovery unit 3 collects the fine pesticide diffused to the environment and inputs the fine pesticide into the primary stirring tank 1 and the secondary stirring tank 2 again, so as to not only prevent the fine pesticide dust from diffusing to the environment, but also ensure the accurate degree of pesticide proportioning and reduce the loss.

[0025] Specifically, the recovery unit 3 comprises a cyclone separator 31 and a fan 32 for air extraction; the air inlet 301 of the cyclone separator 31 is located at the feeding port 101 and used for extracting pesticide powder diffused at the feeding port 101, the air outlet 302 of the cyclone separator 31 is communicated with the primary mixing tank 1, and the dust outlet 303 of the cyclone separator 31 is communicated with the secondary mixing tank 2. Under this design, pesticide powder with smaller particle size reenters the primary mixing tank 1 at the air outlet 302 of the cyclone separator 31, and pesticide powder with larger particle size reenters the secondary mixing tank 2 at the dust outlet 303 of the cyclone separator 31. The cyclone separator 31 achieves the purpose of collecting diffused dust and re-feeding the dust into the device, which not only prevents pesticide powder from diffusing into the air to pollute the environment, but also ensures that the raw materials are used to the maximum extent, thereby significantly improving the utilization rate and the ratio.

[0026] As a preferred embodiment of the present application, a first valve 100 is arranged on the communication pipeline between the dust outlet 303 of the cyclone separator 31 and the secondary mixing tank 2. When the feeding is completed and the primary mixing tank 1 is completed, the cyclone separator 31 stops working, and the first valve 100 is opened to feed the collected pesticide powder into the secondary mixing tank 2 for stirring.

[0027] As a further preferred embodiment of the present application, the air outlet 302 is located in the primary mixing tank 1 and faces the ground. In actual application, the pesticide powder in the primary mixing tank 1 does not exceed the air outlet 302 as much as possible and does not interfere with normal stirring, so as to avoid blocking the air outlet 302.

[0028] As a further preferred embodiment of the present application, a second valve 200 is arranged on the communication pipeline between the primary mixing tank 1 and the secondary mixing tank 2. When the primary mixing tank 1 is completed, the second valve 200 is opened to feed the preliminarily mixed raw materials into the secondary mixing tank 2.

[0030] In the present embodiment, preferably, the secondary mixing tank 2 is a double helix conical mixer, and the bottom thereof is provided with a discharge port 201. Under this preferred design, the double helix structure not only enables the raw materials to be fully stirred, convected, sheared and diffused during the mixing process, thereby achieving rapid and uniform mixing effect, but also enables the discharge port 201 at the bottom to discharge at a high speed and clean and neat, and the bottom can be tightly closed without leakage. Of course, in actual application, the primary mixing tank 1 and the secondary mixing tank 2 each need to be driven by a corresponding stirring paddle through a driving motor 400 to achieve mixing, which is common knowledge in the art, and therefore the present embodiment will not be described in more detail.

[0031] In actual use of the embodiment, a rack 4 is further included; the primary stirring tank 1, the cyclone separator 31 and the secondary stirring tank 2 are all arranged on the rack 4. Of course, the structure of the rack 4 is not limited in the embodiment, and only a simple schematic diagram of one arrangement mode is given, and the length of the pipeline or the shape of the rack 4 can be changed by those skilled in the art, which should be within the protection scope of the embodiment.
