Description

TECHNICAL FIELD

[0001] The utility model relates to screening equipment technical field especially relates to a kind of concentrated feed processing screening equipment. BACKGROUND

[0002] In animal husbandry, in order to improve the growth rate and health status of animals, it is usually necessary to provide concentrated feed with fine proportioning. Concentrated feed, also known as protein supplement feed, is a semi-finished compound feed prepared from protein feed (fish meal, soybean cake, etc.), mineral feed (bone meal, stone powder, etc.) and premix additives. In order to ensure the uniformity of the feed, the produced feed needs to be screened after production, so as to facilitate the subsequent use of concentrated feed.

[0003] Therefore, a concentrated feed processing and screening device with the patent number "CN212576767U" is disclosed in the prior art. When the device is in operation, the feed is screened by the clamping strip, the classification sieve disc, the discharging net, the qualified collection cylinder, the discharging pipe, the substandard collection box and the blocking strip. However, the above-mentioned concentrated feed screening device is screened by the gravity of the feed itself falling and then passing through the classification sieve disc. Therefore, it is necessary to wait for the feed to fall by itself, which leads to a long screening time and the concentrated feed is easily stuck in the classification sieve disc, resulting in low screening efficiency of the device for concentrated feed. SUMMARY

[0004] The utility model aims at solving the problems existing in the above-mentioned background art and provides a concentrated feed processing and screening device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A concentrated feed processing and screening device includes an outer cylinder and a feed hopper bottom collection box. The left and right ends of the outer cylinder upper wall are fixed with feed hoppers. The left bottom of the outer cylinder is embedded with a bottom collection box. The left and right ends of the inner cylinder upper part are respectively fixed with an air guide fan and a servo motor. The middle part of the outer cylinder is vertically connected with a transmission rod. The outer wall of the transmission rod is fixed with a scraper below. The upper and lower ends of the inner cylinder are respectively fixed with an upper filter screen and a lower filter screen. The middle part and the lower part of the right side of the outer cylinder are respectively embedded with an upper discharging plate and a lower discharging plate. The inner upper part of the upper discharging plate and the lower discharging plate is respectively fixed with an electric push rod horizontally. The left side of the push rod output end of the electric push rod is fixed with a baffle.

[0007] Preferably, the upper filter screen is arranged above the lower filter screen. The pore size of the filter holes in the upper filter screen is larger than that of the lower filter screen. The upper filter screen and the lower filter screen are both arranged in a "conical" shape.

[0008] Preferably, the servo motor is rotatably connected to the transmission rod via a chain belt, the bottom end of the scraper is in close contact with the upper surface of the upper and lower filter screens, and the outermost side of the scraper is in close contact with the inner wall of the inner cylinder.

[0009] Preferably, the discharge ports of the upper discharge plate and the lower discharge plate are respectively located on the right side of the upper surface of the upper filter screen and the lower filter screen, and the right side of the upper surface of the upper filter screen and the lower filter screen are on the same horizontal plane as the discharge ports of the upper discharge plate and the lower discharge plate.

[0010] Preferably, the vertical cross-sectional area of ​​the baffle is the same as the vertical cross-sectional area of ​​the discharge openings of the upper and lower discharge plates, and the baffle slides horizontally left and right in the upper and lower discharge plates.

[0011] Preferably, a hollow channel is provided in the middle of the transmission rod, the exhaust end of the induced draft fan is connected to the upper part of the hollow channel of the transmission rod through a pipe, and a flow groove connected to the hollow channel is provided inside the scraper.

[0012] Preferably, the bottom of the scraper is provided with a vertical vent hole, which is located above the filter holes in the upper and lower filter screens, and the vent hole is connected to the flow groove inside the scraper.

[0013] 1. After the feed enters the inner cylinder through the feed hopper, it falls due to gravity and passes through the upper and lower filter screens. Since the pore size of the upper filter screen is larger than that of the lower filter screen, the upper filter screen filters out the larger concentrated feed particles, the lower filter screen filters out the medium-sized concentrated feed particles, and the smaller concentrated particles pass directly through the lower filter screen and fall into the bottom collection box along the inner cylinder. When the upper filter screen filters out the larger and medium-sized concentrated feed particles, the servo motor drives the transmission rod and scraper to rotate through the chain belt. This causes the scraper to push the concentrated particles accumulated on the surface of the upper and lower filter screens, accelerating the speed at which the concentrated particles pass through the filter holes of the upper and lower filter screens. After the concentrated feed is screened, the electric push rod pulls the baffle to the right from the discharge port of the upper and lower discharge plates, allowing the screened concentrated feed to fall from the upper and lower discharge plates, achieving rapid collection of the screened concentrated feed with high screening efficiency.

[0014] 2. During the screening process of concentrated feed, the servo motor drives the transmission rod and scraper to rotate via a chain belt. At the same time, the blower introduces external airflow into the rotating transmission rod through a pipe. The airflow then enters the scraper through the hollow channel on the inner wall of the transmission rod and is discharged from the exhaust hole at the bottom of the scraper, blowing into the filter holes inside the upper and lower filter screens. This allows the concentrated feed to fall quickly from the filter holes, preventing it from getting stuck in the filter holes of the upper and lower filter screens for a long time and affecting the normal screening of the concentrated feed. The screening efficiency is high. Attached Figure Description

[0020] Outer cylinder 1, feed hopper 101, inner cylinder 102, bottom collection box 2, induced draft fan 3, servo motor 301, transmission rod 302, scraper 303, upper filter screen 4, lower filter screen 5, upper discharge plate 6, lower discharge plate 7, electric push rod 8, baffle 801. Detailed Implementation

[0021] Example 1, referring to Figures 1-4 A concentrated feed processing and screening device includes an outer cylinder 1 and a feed hopper 101 and a bottom collection box 2. The feed hopper 101 is fixed to the left and right ends of the upper part of the outer cylinder 1. The bottom collection box 2 is embedded in the left side of the bottom of the outer cylinder 1. The blower 3 and the servo motor 301 are fixed to the left and right ends of the upper part of the outer cylinder 1, respectively. A transmission rod 302 is vertically rotatably connected to the middle of the outer cylinder 1. A scraper 303 is fixed to the lower part of the outer wall of the transmission rod 302. An upper filter screen 4 and a lower filter screen 5 are fixed to the upper and lower ends of the inner cylinder 102, respectively. An upper discharge plate 6 and a lower discharge plate 7 are embedded in the middle and lower part of the right side of the outer cylinder 1, respectively. An electric push rod 8 is horizontally fixed to the upper part of the upper discharge plate 6 and the lower discharge plate 7. A baffle 801 is fixed to the left side of the push rod at the output end of the electric push rod 8.

[0022] The upper filter screen 4 is positioned above the lower filter screen 5. The internal pore diameter of the upper filter screen 4 is larger than that of the lower filter screen 5. Both the upper filter screen 4 and the lower filter screen 5 are arranged in a "conical" shape.

[0023] After the feed enters the inner cylinder 102 along the feed hopper 101, the feed falls due to gravity and passes through the upper filter screen 4 and the lower filter screen 5. Since the pore size of the filter screen 4 is larger than that of the filter screen 5, the upper filter screen 4 filters out the larger concentrated feed, the lower filter screen 5 filters out the medium-sized concentrated feed, and the smaller concentrated particles pass directly through the lower filter screen 5 and fall into the bottom collection box along the inner cylinder 102.

[0024] The servo motor 301 is rotatably connected to the transmission rod 302 via a chain belt. The bottom end of the scraper 303 is in close contact with the upper surface of the upper filter screen 4 and the lower filter screen 5, and the outermost part of the scraper 303 is in close contact with the inner wall of the inner cylinder 102.

[0025] The discharge ports of the upper discharge plate 6 and the lower discharge plate 7 are respectively located on the right side of the upper surface of the upper filter screen 4 and the lower filter screen 5. The right side of the upper surface of the upper filter screen 4 and the lower filter screen 5 is on the same horizontal plane as the discharge ports of the upper discharge plate 6 and the lower discharge plate 7.

[0026] When the upper filter screen 4 filters out larger and medium-sized concentrated feed, the servo motor 301 drives the transmission rod 302 and scraper 303 to rotate via the chain belt. This causes the scraper 303 to push the concentrated particles accumulated on the upper surface of the upper filter screen 4 and the lower filter screen 5, accelerating the speed at which the concentrated particles pass through the filter holes in the upper filter screen 4 and the lower filter screen 5. After the discharge ports of the upper discharge plate 6 and the lower discharge plate 7 are opened, the rotating scraper 303 can quickly push the screened concentrated feed into the discharge ports of the upper discharge plate 6 and the lower discharge plate 7.

[0027] The vertical tangential area of ​​the baffle 801 is the same as the vertical tangential area of ​​the discharge ports of the upper discharge plate 6 and the lower discharge plate 7. The baffle 801 slides horizontally left and right in the upper discharge plate 6 and the lower discharge plate 7.

[0028] After the concentrated feed is screened, the electric push rod 8 pulls the baffle 801 to the right from the discharge port of the upper discharge plate 6 and the lower discharge plate 7, so that the screened concentrated feed falls from the upper discharge plate 6 and the lower discharge plate 7, realizing the rapid collection of the screened concentrated feed and the high screening efficiency.

[0029] Example 2 differs from Example 1 in that, in this example, a hollow channel is provided in the middle of the transmission rod 302, the exhaust end of the induced draft fan 3 is connected to the upper part of the hollow channel of the transmission rod 302 through a pipe, and a flow groove connected to the hollow channel is provided inside the scraper 303.

[0030] The bottom of the scraper 303 is provided with a vertical vent hole, which is located above the filter holes in the upper filter screen 4 and the lower filter screen 5. The vent hole is connected to the flow groove inside the scraper 303.

[0031] During the concentrated feed screening process, the servo motor 301 drives the transmission rod 302 and scraper 303 to rotate via a chain belt. At the same time, the induced draft fan 3 introduces external airflow into the rotating transmission rod 302 through a pipe. The airflow then enters the scraper 303 through the hollow channel on the inner wall of the transmission rod 302 and is discharged from the exhaust hole at the bottom of the scraper 303, blowing into the filter holes inside the upper filter screen 4 and lower filter screen 5. This allows the concentrated feed to fall quickly from the filter holes, preventing it from getting stuck in the filter holes of the upper filter screen 4 and lower filter screen 5 for a long time and affecting the normal screening of the concentrated feed. The screening efficiency is high.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
