Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of edible fungus cultivation, and in particular relates to a stirring and dust removing device for edible fungus cultivation raw materials. Background Art
[0002] The raw materials for edible fungi cultivation are mainly the waste materials of crops, which are processed through primary processing such as drying, grading, crushing, screening, compression and bagging. They include corn cobs, mixed materials (rice bran, wheat bran, corn flour), cottonseed hulls, beet pulp, shell powder, etc. In the factory cultivation of edible fungi, the mixing of raw materials is the first step of the process. The raw materials must be added to the mixing pot in turn, and the mixer must be started to stir for a period of time before adding water and stirring. Finally, the fully automatic bottling machine is used for bottling, so as to provide high-quality culture medium for subsequent inoculation and cultivation of mushrooms. The dry mixing of the raw materials in the mixing pot after feeding is the most important step. Since the particles of the raw materials are small, it is easy to produce large dust, which not only affects the workshop operating environment, but also poses a great safety hazard to the health of employees due to long-term inhalation of dust, and is easy to cause occupational hazards (pneumoconiosis). The existing temporary solution is to use a high-power industrial fan to blow air next to the feeding operation to disperse the dust and reduce human inhalation, but this method can only solve the local short-term dust diffusion. After a long time, except for the mixing area, other working areas of the workshop are still filled with a large amount of dust, which seriously affects the work of personnel in other positions. Therefore, it is urgent to provide a edible fungus cultivation raw material mixing and dust removal device to solve the problem of large dust in the raw material feeding and mixing process, thereby improving the workshop working environment and reducing the harm of dust to the health of employees.

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] like Figure 1 As shown, a device for mixing and dust removal of raw materials for edible fungi cultivation includes a negative pressure fan 1, a dust collector 2 and a dust removal main pipe 3. The negative pressure fan is connected to the dust collector, which is connected to the dust removal main pipe. The dust collector adopts a bag dust collector. At least one dust removal branch pipe 5 is connected between the dust removal main pipe and each mixing pot 4. Two dust removal branch pipes are connected between the dust removal main pipe and each mixing pot. Each dust removal branch pipe is connected to the upper side of the corresponding mixing pot to facilitate the adsorption of dust. When the negative pressure fan is started, negative pressure is formed in the dust removal main pipe, and the dust in the mixing pot is adsorbed. The adsorbed dust enters the dust collector through the dust removal branch pipe and the dust removal main pipe, and the air purified by dust removal is discharged to the outside, keeping the air in the workshop clean and healthy.
[0028] like Figure 2 As shown, at least two dust cleaning control bins 6 are evenly spaced and connected to the dust removal main pipe, and each dust cleaning control bin is equipped with a high-pressure air outlet hose 7 connected to the dust removal main pipe, and each high-pressure air outlet hose is connected to a high-pressure air supply pipe 9 located on one side of the dust removal main pipe through an electromagnetic valve 8. A high-pressure gas storage tank 10 is connected to the high-pressure air supply pipe, and the delivery of high-pressure gas in each high-pressure air outlet hose is controlled by the electromagnetic valve. When the equipment is in a long-term dust removal working state, dust will accumulate in the dust removal main pipe. The dust can be lifted up by blowing the inside of the dust removal main pipe with compressed air, and the dust inside the dust removal main pipe can be removed with the help of the negative pressure fan.
[0029] like Figure 2 and Figure 3As shown, an inspection plate 11 is connected between each dust cleaning control bin and the dust removal main pipe. The inspection plate and the mounting groove 12 arranged on the side wall of the dust removal main pipe are detachably connected to facilitate the repair and maintenance of the equipment. A first sealing gasket 13 is arranged on the side wall of the mounting groove to ensure the sealing of the connection between the inspection plate and the dust removal main pipe. A window is provided on the inspection plate, and a movable baffle 14 is hinged on the window. The movable baffle separates the inner cavity of the dust cleaning control bin from the inner cavity of the dust removal main pipe, and its outer diameter matches the inner diameter of the dust removal main pipe. A cavity 15 is arranged inside the movable baffle, and it is close to the dust removal. One side of the inner cavity of the dust main pipe is connected to an air outlet, and the other side is connected to a cylinder 16. The cylinder is connected to a cleaning control bin, and a high-pressure air outlet hose is connected to the cavity. A second sealing gasket 17 is provided on the inner wall of the window to ensure the sealing of the connection between the movable baffle and the window. The cleaning control bin is tilted toward the side away from the dust collector, and the side of the movable baffle close to the dust collector is hinged to the inspection plate. When the cylinder output shaft is extended, the movable baffle is driven to open. At this time, the air outlet of the movable baffle faces the side of the dust collector, which can effectively blow the dust in the dust removal main pipe toward the dust collector, thereby enhancing the cleaning effect.
[0030] Combination Figure 3 and Figure 4 As shown, the air outlet includes a central air outlet 18, at least four first air outlets 19 and at least four second air outlets 20. The central air outlet is located at the center of the baffle. In this embodiment, the number of first air outlets is 6, and the number of second air outlets is 9. The 6 first air outlets are distributed in a circular array, which is a first air outlet group, and the 9 second air outlets are distributed in a circular array, which is a second air outlet group. The first air outlet group, the second air outlet group and the central air outlet are located on the same central axis, and each of the first air outlet and the second air outlet is inclined to the side away from the central air outlet, so that the compressed air outlet direction on the movable baffle is trumpet-shaped and diffuses outward, thereby improving the cleaning efficiency.
[0031] The utility model can utilize a PLC controller to centrally and uniformly control the operations of the solenoid valves, cylinders, negative pressure fans and dust collectors, which will not be described in detail in this embodiment.
[0032] The working principle of the utility model is as follows:
[0033] like Figures 1 to 4 As shown, during the process of feeding and stirring each mixing pot, the negative pressure fan is started, and negative pressure is formed inside the dust removal main pipe and the dust removal branch pipe to adsorb the dust generated in the mixing pot. After being filtered by the dust collector, the dust is collected and centrally processed, and clean air is discharged to the outside, which effectively improves the air environment of the workshop.
[0034] During the long-term dust removal process, dust will accumulate inside the dust removal pipe, which requires regular cleaning by staff. The cleaning process is as follows (see the attached manual). Figure 2 , taking 3 dust cleaning control bins as an example):
[0035] (1) Start the cylinder on the dust cleaning control bin farthest from the dust collector to control the movable baffle to swing into the dust collecting main pipe. At this time, the air outlet on the movable baffle is set toward the dust collector. Then start the solenoid valve on the corresponding high-pressure air outlet hose to provide compressed air. The compressed air is discharged through the high-pressure air outlet hose and the cavity in the movable baffle, and then from the central air outlet, the first air outlet, and the second air outlet to purge the dust accumulated in the dust collecting main pipe. Then turn on the negative pressure fan to absorb and filter the dust in the dust collecting main pipe.
[0036] (2) After a period of dust removal in step (1), close the solenoid valve in step (1), and control the cylinder to contract, and then open the cylinder and solenoid valve corresponding to the adjacent dust removal control bin, and perform dust removal in the same manner as step (1);
[0037] (3) Follow the above steps and clean the inside of the dust removal main pipe in sections step by step to complete the cleaning work inside the entire dust removal main pipe.
[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
