Description

Technical Field

[0001] The invention belongs to the technical field of screening devices, in particular to a linear vibrating screen for producing amino acid compound fertilizer. Background Art

[0002] The linear vibrating screen uses the vibration motor as the vibration power source to throw the material on the screen and move forward linearly. The material enters the feed port of the screening machine evenly from the feeder, and passes through the multi-layer screen to produce several specifications of oversize and undersize, which are discharged from their respective outlets. It has low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust spillage, automatic discharge, and is more suitable for assembly line operation.

[0003] When the linear vibrating screen is used to screen and process amino acid compound fertilizer, since the fertilizer particles are small, the fertilizer particles that fall through the screen will be separated from the internal impurity blocks and agglomerated and deteriorated fertilizer particles, thereby obtaining more refined fertilizer raw materials. However, the impurities remaining on the linear vibrating screen will gradually affect the filtering capacity of the screen itself during the continuous operation of the device, and the fertilizer that jumps irregularly on the screen will easily enter the interior of the device from the side port of the device, which will lead to the problem that the inner cavity of the device is easily stuck by the fertilizer, so improvement is needed. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention adopts the following technical solution to solve the technical problems: a linear vibrating screen for amino acid compound fertilizer production, comprising a screening box, a material containing frame is fixedly connected to the axis at the bottom of the inner cavity of the screening box, and the steering filter plate can perform linear vibration screening on the fertilizer put in, special clamps are slidably connected to both sides of the inner cavity of the steering filter plate through grooves, an angle device is rotatably connected to the axis of the inner cavity of the steering filter plate, and a guide plate is rotatably connected to one side of the surface of the steering filter plate; when the device is used to screen the fertilizer, the fertilizer to be screened is first poured onto the guide plate at the left end, and then the inclination of the guide plate is controlled by an external torque rod so that the fertilizer on the guide plate enters the upper part of the internal steering filter plate for screening processing.

[0005] Preferably, a wind pressure component is located at the top of the inner cavity of the screening box, and the wind pressure component can gather the fertilizer below to the middle of the steering filter plate through wind force; the device can not only filter and screen the input fertilizer particles, but also guide the screened particles to always be close to the axis of the steering filter plate through the upper wind pressure component during the screening process, thereby avoiding the problem of fertilizer particles jumping irregularly on the screen, easily entering the interior of the device from the side port of the device, and causing the inner cavity of the device to be easily stuck by fertilizer.

[0006] Preferably, an oscillating component can provide a vibration force for the device, and the oscillating component has a sliding bottom cylinder, the top of the sliding bottom cylinder surface is slidably connected to a spring sleeve, the bottom of the sliding bottom cylinder inner cavity is fixedly connected to a bottom rotating frame, and the top of the bottom rotating frame surface is rotatably connected to a thrust rotating plate, the surface of the thrust rotating plate is slidably connected to a spring inner rod, the top of the spring inner rod surface is fixedly connected to a traction side rod, and the middle of the traction side rod surface is rotatably connected to one end of the steering filter plate inner cavity. The bottom of the sliding bottom cylinder surface is slidably connected to the bottom of the screening box inner cavity through a guide chute, the top of the spring inner rod surface is slidably connected to the axis of the top of the spring sleeve inner cavity, both sides of the guide plate surface are rotatably connected to torque rotating rods, and the end of the torque rotating rod away from the guide plate is fixedly connected to one side of the screening box surface through a rotating motor. The angle deflection device includes a vertical guide plate, the top of the inner cavity of the vertical guide plate is slidably connected to a control column via a filling slider, the bottom of the surface of the control column is fixedly connected to a shock-absorbing spring belt via a filling slider, the bottom end of the shock-absorbing spring belt is fixedly connected to a bottom spray box, both sides of the inner cavity of the vertical guide plate are slidably connected to side clamps via slots, and both sides of the surface of the side clamps are fixedly connected to side support rods. Since the straight steering filter plate cannot guide the fertilizer to move in a directional manner, the steering filter plate needs to be tilted by the deflection devices on both sides. The control columns on both sides deflect the steering filter plate to the lower right by a certain angle through the plug rod of the axis, so that the deflection angle of the steering filter plate is kept at a certain value, and then the oscillation component at the bottom starts to work, and the thrust rotating plate starts to rotate at a high speed under the action of the rotating frame, and then the top of the thrust rotating plate will periodically push the spring inner rod upward, so that the spring inner rod has a moving effect on the traction side rod. Since the moving action of the four traction side rods is the same, the steering filter plate begins to vibrate at a high frequency, and the wind pressure component on the top also starts to blow air to the fertilizer particles moving below, so that the particles move closer to the axis of the steering filter plate during the vibration and sliding process. The device can control the overall tilt angle of the steering filter plate by adjusting the control column angle, and then control the movement speed of the fertilizer on the upper surface of the steering filter plate, so as to avoid the problem that the fertilizer particles jump too much on the upper surface of the steering filter plate, resulting in the inability to effectively pass through the special clamps on both sides to achieve the filtering effect.

[0007] Preferably, a clamping roller is evenly arranged on one side of the inner cavity of the side clamp plate close to the vertical guide plate, and the surface of the clamping roller is rollingly connected to the surface of the control column through a filling slider, the bottom end of the side support rod is fixedly connected to the bottom of the inner cavity of the screening box, and the top end of the output shaft of the control column is fixedly connected to the middle of the inner cavity of the steering filter plate through an adapter socket. The bottom spray box includes a filling box shell, the top of the inner cavity of the filling box shell is slidably connected to a pressing slide, the bottom of the inner cavity of the pressing slide is evenly arranged with a heating resistor, the inner cavity of the filling box shell is fixedly connected to a through rod on one side close to the material holding frame, and the through rod extends to the inside of the material holding frame at one end away from the filling box shell, and the top of the surface of the pressing slide is fixedly connected to the bottom end of the shock-absorbing spring belt. During the vibration of the steering filter plate, the control column will also be pulled to slide up and down along the inner cavity of the vertical guide plate. At this time, the control column squeezes and pulls the damping spring belt below through the sliding shell on the outer surface. The damping spring belt not only has a damping effect, but also can convert the vibration force into traction on the vertical plane, controlling the downward pressure slide plate below to slide downward along the inner cavity of the filling box shell. Since the inner cavity temperature of the filling box shell is high after being heated by the heating resistor, the downward pressure slide plate compressed inward can discharge the high-temperature gas in the inner cavity of the filling box shell into the material holding frames on both sides through the through-insertion rod. The device reduces the vibration force on the control column through the damping spring belt, and converts the vibration force into the power of spraying gas into the inner cavity of the material holding frame through the bottom spray box. On the one hand, it can break up the fertilizer particles accumulated inside the material holding frame to avoid adhesion and agglomeration. On the other hand, the heated gas can dry the fertilizer from the bottom to the top, thereby ensuring that the fertilizer is dry and avoids moisture.

[0008] Preferably, the special clamping plate comprises parallel filter plates, and connecting plugs are fixedly connected on both sides of the middle of the inner cavity of the parallel filter plates, and the end of the connecting plug away from the parallel filter plates is rotatably connected to a threaded rotating rod, and the surface of the threaded rotating rod is fixedly connected to a fixed jacket, and the end of the connecting plug close to the parallel filter plates is rotatably connected to an arc-shaped rotating plate. When the particles pass through the special clamping plates on the left and right sides respectively, due to the different sizes of the leakage holes of the special clamping plates on both sides, the particles can filter smaller impurities into the material holding frame on the left when passing through the special clamping plate on the left, and then the particles can leave larger impurities on the upper surface of the special clamping plate when passing through the special clamping plate on the right, and normal fertilizer particles can fall into the material holding frame through the special clamping plate on the right to complete the collection work.

[0009] Preferably, the number of the special clamping plates is two, the surface of the special clamping plates is slidably connected to the inner cavity of the steering filter plate, the inner cavity of the parallel filter plate is uniformly provided with filter ports, and the end of the fixed sleeve away from the arc-shaped rotating plate is fixedly connected to the inner cavity of the steering filter plate through an adapter socket. Since the special clamping plates on both sides of the device can be retracted up and down by the threaded rotating rod, the fertilizer can be restricted to the range where the special clamping plates on both sides are located for a long time of screening, avoiding the problem of poor screening effect caused by excessive sliding of the fertilizer, and the special clamping plates on both sides can respectively screen out larger impurities and smaller impurities from the fertilizer, avoiding the problem of missed screening and wrong screening.

[0010] Preferably, the wind pressure component includes an upper shell, a main fan is fixedly connected to the axis of the inner cavity of the upper shell, plug-in fans are fixedly connected to both sides of the main fan surface through connecting rods, the bottom end of the main fan output shaft is fixedly connected to an adapter plate through a guide sleeve, and the bottom of the inner cavity of the adapter plate is fixedly connected to a guide hollow tube. When the fertilizer particles slide along the upper surface of the parallel filter plate, the outer shell of the main fan pulls the plug-in fans on both sides, and the output shaft of the plug-in fans is inserted into the adapter plate below. At this time, the output shaft at the bottom of the main fan and the output shaft at the bottom of the plug-in fan both blow air downward through the adapter plate, and under the guidance of the oblique guide hollow tube, the fertilizer particles dispersed on both sides are blown toward the axis of the parallel filter plate to prevent the fertilizer particles from entering the inner cavity of the device.

[0011] Preferably, both sides of the adapter plate surface are fixedly connected to the middle of the inner cavity of the screening box, the top of the upper shell surface is fixedly connected to the top of the inner cavity of the screening box, and the bottom end of the plug-in fan output shaft is slidably connected to both sides of the top of the inner cavity of the adapter plate through the plug interface. The two sides of the inner cavity of the adapter plate are slidably connected with sliding inner plates, and the left and right sides of the inner cavity of the adapter plate are fixedly connected with pressure-sensitive plates. After the fertilizer processing is completed, it is necessary to clean the upper surface of the fertilizer parallel filter plate. At this time, the plug-in fans on both sides exhaust air from the bottom through the adapter plate, and the impurities and dust on the upper surface of the steering filter plate are sucked into the interior of the adapter plate, but the main fan will continue to blow air into the interior of the adapter plate, and then blow the impurities filtered in the upper opening of the inner cavity of the adapter plate into the sliding inner plates on both sides, thereby avoiding the problem of clogging of the adapter plate.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device can not only filter and screen the fertilizer particles, but also guide the screened particles to always approach the axis of the steering filter plate through the wind pressure component above during the screening process, thereby avoiding the problem that the fertilizer particles jump irregularly on the screen and easily enter the interior of the device from the side port of the device, which may cause the inner cavity of the device to be easily stuck by the fertilizer.

[0014] 2. The device can control the overall inclination angle of the steering filter plate by adjusting the rotation angle of the control column, thereby controlling the movement speed of the fertilizer on the upper surface of the steering filter plate, thereby avoiding the problem that the fertilizer particles jump too much on the upper surface of the steering filter plate and cannot effectively pass through the special clamping plates on both sides to achieve the filtering effect.

[0015] 3. The device reduces the vibration force on the control column through the shock-absorbing spring belt, and converts the vibration force into power for spraying gas into the inner cavity of the material frame through the bottom spray box. On the one hand, it can break up the fertilizer particles accumulated inside the material frame to avoid adhesion and agglomeration. On the other hand, the heated gas can dry the fertilizer from bottom to top, thereby ensuring that the fertilizer is dry and avoids moisture.

[0016] 4. Since the special clamping plates on both sides of the device can be retracted up and down through the threaded rotating rod, the fertilizer can be confined to the range of the special clamping plates on both sides for long-term screening, avoiding the problem of fertilizer sliding too fast and causing poor screening effect. In addition, the special clamping plates on both sides can respectively screen out larger impurities and smaller impurities from the fertilizer, avoiding the problems of missed screening and wrong screening.

[0017] 5. The adapter plate of the device can not only serve as a transfer to guide the movement of the fertilizer, but also clean the upper surface of the fertilizer parallel filter plate after the fertilizer is processed. In order to prevent impurities from blocking the opening at the bottom of the plug-in fan, the main fan can cooperate with the plug-in fans on both sides to blow the impurities filtered in the opening above the inner cavity of the adapter plate into the sliding inner plates on both sides, thereby avoiding blockage of the adapter plate.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms.

[0028] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a linear vibration screen for amino acid compound fertilizer production, comprising a screening box 1, a material holding frame 11 is fixedly connected to the axis of the bottom of the inner cavity of the screening box 1, and comprises a steering filter plate 3, the steering filter plate 3 can perform linear vibration screening on the fertilizer put in, both sides of the inner cavity of the steering filter plate 3 are slidably connected with special clamping plates 5 through grooves, the axis of the inner cavity of the steering filter plate 3 is rotatably connected with a deflection device 2, and one side of the surface of the steering filter plate 3 is rotatably connected with a guide plate 31;

[0029] A wind pressure component 6, which is located at the top of the inner cavity of the screening box 1, and the wind pressure component 6 can gather the fertilizer below to the middle of the steering filter plate 3 through wind force;

[0030] The oscillating component 4 can provide a vibration force for the device. The oscillating component 4 has a sliding bottom cylinder 41. The top of the surface of the sliding bottom cylinder 41 is slidably connected to a spring sleeve 43. The bottom of the inner cavity of the sliding bottom cylinder 41 is fixedly connected to a bottom rotating frame, and the top of the surface of the bottom rotating frame is rotatably connected to a thrust rotating plate 42. The surface of the thrust rotating plate 42 is slidably connected to a spring inner rod 44. The top of the surface of the spring inner rod 44 is fixedly connected to a traction side rod 45. The middle part of the surface of the traction side rod 45 is rotatably connected to one end of the inner cavity of the steering filter plate 3.

[0031] The bottom of the sliding bottom cylinder 41 surface is slidably connected to the bottom of the inner cavity of the screening box 1 through a guide groove, the top of the surface of the spring inner rod 44 is slidably connected to the axis of the top of the inner cavity of the spring sleeve 43, and the torque rod 32 is rotatably connected to both sides of the surface of the guide plate 31, and the end of the torque rod 32 away from the guide plate 31 is fixedly connected to one side of the surface of the screening box 1 through a rotating motor.

[0032] The angle deflection device 2 includes a vertical guide plate 21, the top of the inner cavity of the vertical guide plate 21 is slidably connected to a control column 22 through a filling slider, the bottom of the surface of the control column 22 is fixedly connected to a shock-absorbing spring belt 25 through a filling slider, the bottom end of the shock-absorbing spring belt 25 is fixedly connected to a bottom spray box 7, and both sides of the inner cavity of the vertical guide plate 21 are slidably connected to side clamps 23 through slots, and both sides of the surface of the side clamps 23 are fixedly connected to side support rods 24.

[0033] Clamping rollers are evenly arranged on one side of the inner cavity of the side clamping plate 23 close to the vertical guide plate 21, and the surface of the clamping roller is rollingly connected to the surface of the control rotating column 22 through a filling slider, the bottom end of the side support rod 24 is fixedly connected to the bottom of the inner cavity of the screening box 1, and the top end of the output shaft of the control rotating column 22 is fixedly connected to the middle part of the inner cavity of the steering filter plate 3 through an adapter socket.

[0034] The bottom spray box 7 includes a filling box shell 71, and a downward pressing slide 73 is slidably connected to the top of the inner cavity of the filling box shell 71, and heating resistors 74 are evenly arranged at the bottom of the inner cavity of the downward pressing slide 73. A penetrating rod 72 is fixedly connected to the side of the inner cavity of the filling box shell 71 close to the material holding frame 11, and the end of the penetrating rod 72 away from the filling box shell 71 extends to the interior of the material holding frame 11, and the top of the surface of the downward pressing slide 73 is fixedly connected to the bottom end of the shock-absorbing spring belt 25.

[0035] When the device is used to screen fertilizers, the fertilizer to be screened is first poured onto the guide plate 31 at the left end, and then the inclination of the guide plate 31 is controlled by the external torque rod 32, so that the fertilizer on the guide plate 31 enters the upper part of the internal turning filter plate 3 for screening processing.

[0036] Since the straight steering filter plate 3 cannot guide the fertilizer to move in a directional manner, the steering filter plate 3 needs to be tilted by the deflection devices 2 on both sides. The control columns 22 on both sides deflect the steering filter plate 3 to the lower right at a certain angle through the axial insertion rod and then fix it, so that the deflection angle of the steering filter plate 3 is maintained at a certain value. Then the oscillation component 4 at the bottom starts to work, and the thrust rotating plate 42 starts to rotate at high speed under the action of the rotating frame. Then the top of the thrust rotating plate 42 will periodically push the spring inner rod 44 upward, so that the spring inner rod 44 has a moving effect on the traction side rod 45. Since the moving actions of the four traction side rods 45 are the same, the steering filter plate 3 starts to vibrate at a high frequency, and the wind pressure component 6 on the top also starts to blow air to the fertilizer particles moving below, so that the particles move closer to the axis of the steering filter plate 3 during the vibration and sliding process.

[0037] When the particles pass through the special clamps 5 on the left and right sides respectively, due to the different sizes of the leakage holes of the special clamps 5 on both sides, the particles can screen out smaller impurities and drop them into the material holding frame 11 on the left when passing through the special clamps 5 on the left, and then when the particles pass through the special clamps 5 on the right, the larger impurities can be left on the upper surface of the special clamps 5, and normal fertilizer particles can pass through the special clamps 5 on the right and fall into the material holding frame 11 to complete the collection work.

[0038] As the steering filter plate 3 vibrates, it will also pull the control column 22 to slide up and down along the inner cavity of the vertical guide plate 21. At this time, the control column 22 squeezes and pulls the shock-absorbing spring belt 25 below through the sliding shell on the outer surface. The shock-absorbing spring belt 25 not only has a shock-absorbing effect, but also can convert the vibration force into traction on the vertical plane, controlling the downward pressure slide plate 73 below to slide downward along the inner cavity of the filling box shell 71. Since the inner cavity temperature of the filling box shell 71 is relatively high after being heated by the heating resistor 74, the inwardly compressed downward pressure slide plate 73 can discharge the high-temperature gas in the inner cavity of the filling box shell 71 through the penetrating rod 72 to the material holding frames 11 on both sides.

[0039] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the special splint 5 includes a parallel filter plate 51, and connecting blocks 54 are fixedly connected on both sides of the middle of the inner cavity of the parallel filter plate 51, and the end of the connecting block 54 away from the parallel filter plate 51 is rotatably connected to a threaded rotating rod 52, and the surface of the threaded rotating rod 52 is fixedly connected to a fixed sleeve 53, and the end of the connecting block 54 close to the parallel filter plate 51 is rotatably connected to an arc-shaped rotating plate 55.

[0040] There are two special splints 5, the surface of which is slidably connected to the inner cavity of the steering filter plate 3, the inner cavity of the parallel filter plate 51 is evenly provided with filter ports, and the end of the fixed sleeve 53 away from the arc-shaped rotating plate 55 is fixedly connected to the inner cavity of the steering filter plate 3 through an adapter socket.

[0041] The wind pressure component 6 includes an upper top shell 61, a main fan 62 is fixedly connected to the axis center of the inner cavity of the upper top shell 61, plug-in fans 63 are fixedly connected to both sides of the surface of the main fan 62 through connecting rods, the bottom end of the output shaft of the main fan 62 is fixedly connected to an adapter plate 65 through a guide sleeve 64, and a guide hollow tube 66 is fixedly connected to the bottom of the inner cavity of the adapter plate 65.

[0042] Both sides of the surface of the adapter plate 65 are fixedly connected to the middle of the inner cavity of the screening box 1, the top of the surface of the upper top shell 61 is fixedly connected to the top of the inner cavity of the screening box 1, and the bottom end of the output shaft of the plug-in fan 63 is slidably connected to both sides of the top of the inner cavity of the adapter plate 65 through the plug-in interface.

[0043] When the fertilizer particles reach the area where the parallel filter plates 51 are located, the threaded rotating rod 52 in the inner cavity of the fixed outer sleeve 53 controls the connecting plugs 54 on both sides to clamp each other. At this time, the arc-shaped rotating plate 55 is bent and compressed, and the parallel filter plates 51 on both sides are pulled closer. At this time, the fertilizer particles enter the grooves of the steering filter plate 3 and are continuously screened. After the fertilizer has been processed on the upper surface of the left parallel filter plate 51 for a period of time, the threaded rotating rod 52 pulls apart the parallel filter plates 51 on both sides, and the top parallel filter plate 51 lifts up the screened fertilizer particles above, and then the fertilizer enters the grooves of the right parallel filter plate 51 along the upper surface of the steering filter plate 3 to repeat the screening process.

[0044] When the fertilizer particles slide along the upper surface of the parallel filter plate 51, the outer shell of the main fan 62 pulls the plug-in fans 63 on both sides, and inserts the output shaft of the plug-in fans 63 into the adapter plate 65 below. At this time, the output shaft at the bottom of the main fan 62 and the output shaft at the bottom of the plug-in fan 63 both blow air downward through the adapter plate 65. Under the guidance of the oblique guiding hollow tube 66, the fertilizer particles dispersed on both sides are blown toward the axis of the parallel filter plate 51 to prevent the fertilizer particles from entering the inner cavity of the device.

[0045] Sliding inner plates 67 are slidably connected to both sides of the inner cavity of the adapter plate 65, and pressure-sensitive plates 68 are fixedly connected to the left and right sides of the inner cavity of the adapter plate 65. After the fertilizer is processed, it is necessary to clean the upper surface of the fertilizer parallel filter plate 51. At this time, the plug-in fans 63 on both sides exhaust air from the bottom through the adapter plate 65, and draw the impurities and dust on the upper surface of the steering filter plate 3 into the interior of the adapter plate 65. However, the main fan 62 will continue to blow air into the interior of the adapter plate 65, and then blow the impurities filtered in the upper opening of the inner cavity of the adapter plate 65 into the sliding inner plates 67 on both sides, thereby avoiding blockage of the adapter plate 65.

[0046] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
