Description

Technical Field

[0001] This utility model relates to the technical field of water-soluble fertilizer production equipment, specifically to a cleaning mechanism for a water-soluble fertilizer rolling screen. Background Technology

[0002] Water-soluble fertilizer is a compound fertilizer containing elements such as nitrogen, phosphorus, potassium, calcium, magnesium, amino acids, humic acid, and alginic acid, which can be completely dissolved in water. In actual production of water-soluble fertilizer, a water-soluble fertilizer rotary screen is required to complete the screening of water-soluble fertilizer particles. When using the water-soluble fertilizer rotary screen, it is necessary to equip it with a hole cleaning mechanism to clean the screen holes. In actual use, it has the advantages of simple operation, stable structure, and good performance.

[0003] The prior art discloses a drum screen for water-soluble fertilizer production, with announcement number CN214917907U. In this utility model, an air pump can draw air into the interior of the mounting housing, but the air pump's inlet end has no filter structure. When the air contains impurities, these impurities will accumulate inside the mounting housing, clogging the jet nozzle and affecting the continuous use of this utility model. At the same time, the air inside the mounting housing can be ejected through the jet nozzle, but the mounting housing has no airtightness detection structure. When there is a leak in the mounting housing, it will affect the air being ejected through the jet nozzle, reducing the practicality of this utility model.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0007] (II) Technical Solution

[0008] To achieve the advantages of having a filtration structure to prevent impurities in the air from entering the gas storage space and an airtightness detection structure to detect whether the gas storage space is a sealed structure, the specific technical solution adopted by this utility model is as follows:

[0009] A cleaning mechanism for a water-soluble fertilizer rotary sieve includes an arc-shaped plate with an arc-shaped cavity inside. Multiple sets of air jet pipes are fixedly inserted through the inner wall of the arc-shaped cavity, and each set of air jet pipes has a first solenoid valve on its side wall. A control panel, an air pump, and a right-angle bracket are mounted on the upper part of the arc-shaped plate. An air inlet pipe is connected to the outlet end of the air pump, and one end of the air inlet pipe is inserted into the arc-shaped cavity. A three-way pipe is connected to the air inlet end of the air pump. An mounting plate is mounted on the side wall of the air pump, and a fixing plate is mounted on the end face of the mounting plate. First pistons are slidably mounted inside both ends of the three-way pipe. Two sets of guide plates slide through one side of the fixing plate, and one end of each set of guide plates is fixedly connected to the two sets of first pistons. Multiple sets of filter screens penetrate the outer walls of both ends of the three-way pipe. A forward and reverse motor is mounted on the rear end face of the mounting plate, and a gear is sleeved on the output end of the forward and reverse motor. Serrated plates are mounted on the opposing surfaces of the two sets of guide plates.

[0010] Furthermore, the gear meshes with the two sets of sawtooth plates.

[0011] Furthermore, a gas guide tube is fixedly inserted through the inner wall of the arc-shaped cavity, and a gas storage cylinder is fixedly sleeved on one end of the gas guide tube. A second solenoid valve is provided on the side wall of the gas guide tube. A second piston is slidably installed inside the gas storage cylinder, and a connecting rod is installed at one end of the second piston.

[0012] Furthermore, the outer wall of the gas storage cylinder is provided with scale markings.

[0013] Furthermore, the control panel is electrically connected to the air pump, multiple sets of the first solenoid valves, and the forward and reverse motors via wires.

[0014] Furthermore, the lower part of the arc-shaped plate is provided with bristles.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a cleaning mechanism for a water-soluble fertilizer rotary screen, which has the following beneficial effects:

[0017] (1) This utility model adopts a three-way pipe. When using the cleaning mechanism of the water-soluble fertilizer rolling screen, the control panel is used to open and close multiple sets of first solenoid valves, and at the same time, the air pump and the forward and reverse motor are working. The output end of the forward and reverse motor drives the gear to rotate clockwise. Since the gear meshes with the two sets of sawtooth plates, the clockwise rotating gear can push the upper set of sawtooth plates to the right. At the same time, the clockwise rotating gear can push the lower set of sawtooth plates to the left. When the upper set of pistons moves to the right of the upper multiple sets of filter screens, the lower set of pistons will move to the left of the lower multiple sets of filter screens. The air pump can draw air into the interior of the three-way pipe through the upper multiple sets of filter screens. During this process, the upper multiple sets of filter screens can intercept impurities in the air. The air is then drawn into the interior of the arc-shaped cavity through the air inlet pipe. The air inside the arc-shaped cavity... Multiple sets of air jets can be used to blow away blockages inside the drum screen holes. When it is necessary to clean the upper sets of filters, the control panel is used to drive the output end of the forward and reverse motor to rotate the gear counterclockwise. The counterclockwise rotating gear pushes the upper set of sawtooth plates to the left, and at the same time, it pushes the lower set of sawtooth plates to the right. When the upper set of pistons moves to the left of the upper sets of filters, the lower set of pistons moves to the right of the lower sets of filters. The air pump can draw air through the lower sets of filters into the interior of the three-way pipe, while cleaning the upper sets of filters. The three-way pipe has a filtering structure, which can prevent impurities in the air from entering the air storage space, ensuring the continuous use of the cleaning mechanism of the water-soluble fertilizer drum screen.

[0018] (2) This utility model adopts a right-angle frame. When using the cleaning mechanism of the water-soluble fertilizer rotary screen, it is necessary to test the sealing of the arc cavity. Using the control panel, multiple sets of first solenoid valves are closed, and the second solenoid valve is opened and closed at the same time. At this time, when the air pump draws air into the interior of the arc cavity, some air will enter the interior of the air storage cylinder through the air guide pipe. This part of the air can push the second piston to move upward. The second piston can squeeze the telescopic spring through the connecting rod and a set of limit plates below. The specific position of the second piston can be known by the scale markings. At this time, the air pump is stopped. When there is a leak in the arc cavity, the telescopic spring is subjected to its own elastic force and can push the set of limit plates below to move the connecting rod and the second piston downward. At this time, the position of the second piston can be known by the scale markings. When the second piston moves, it indicates that there is a leak in the arc cavity. When the second piston does not move, it indicates that there is no leak in the arc cavity. The right-angle frame has an airtightness detection structure, which can detect whether the air storage space is a sealed structure, thus improving the practicality of the cleaning mechanism of the water-soluble fertilizer rotary screen.

[0029] In one embodiment, gear 14 meshes with two sets of saw blades 15, ensuring that gear 14 can drive the two sets of saw blades 15 to move.

[0030] In one embodiment, an air guide pipe 17 is fixedly inserted through the inner wall of the arc-shaped cavity 2, and an air storage cylinder 18 is fixedly sleeved on one side wall of the air guide pipe 17. A second solenoid valve 21 is provided on the side wall of the air guide pipe 17. A second piston 19 is slidably installed inside the air storage cylinder 18, and a connecting rod 20 is installed at one end of the second piston 19.

The right-angle frame 4 has an airtightness detection structure, which can detect whether the air storage space is a sealed structure, thus improving the practicality of the hole cleaning mechanism for the water-soluble fertilizer rolling screen.

[0031] In one embodiment, the outer wall of the gas storage cylinder 18 is provided with scale markings.

[0032] In one embodiment, the control panel is electrically connected to the air pump 3, multiple sets of first solenoid valves 6, and forward and reverse motors via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0033] In one embodiment, the lower part of the arc plate 1 is provided with bristles 7, which can wipe and clean the external drum screen.

[0034] Working principle:

[0035] When using the cleaning mechanism of the water-soluble fertilizer rotary screen, the control panel is used to open and close multiple sets of first solenoid valves 6, simultaneously activating the air pump 3 and the forward / reverse motor. The output of the forward / reverse motor drives gear 14 to rotate clockwise. Since gear 14 meshes with two sets of serrated plates 15, the clockwise rotation of gear 14 pushes the upper set of serrated plates 15 to the right. At the same time, the clockwise rotation of gear 14 pushes the lower set of serrated plates 15 to the left. When the upper set of pistons moves to the right of the upper multiple sets of filter screens 16, the lower set of pistons moves to the left of the lower multiple sets of filter screens 16. The air pump 3 draws air through the upper multiple sets of filter screens 16 into the interior of the three-way pipe 9. During this process, the upper multiple sets of filter screens 16... It can intercept impurities in the air, and the air is then drawn into the arc-shaped cavity 2 through the air intake pipe 8. The air inside the arc-shaped cavity 2 can be ejected through multiple sets of jet pipes 5. The ejected air can blow away the blockages inside the screen holes of the drum screen. When it is necessary to clean the upper multiple sets of filters 16, the output end of the forward and reverse motor is driven by the control panel to rotate the gear 14 counterclockwise. The counterclockwise rotating gear 14 can push the upper set of serrated plates 15 to the left. At the same time, the counterclockwise rotating gear 14 can push the lower set of serrated plates 15 to the right. When the upper set of pistons moves to the left of the upper multiple sets of filters 16, the lower set of pistons will move to the right of the lower multiple sets of filters 16. The air pump 3 can draw air through the lower multiple sets of filters 16 into the three... Inside the through-pipe 9, multiple sets of filters 16 above can be cleaned. The three-way pipe 9, with its filtration structure, prevents impurities in the air from entering the air storage space, ensuring the continuous use of the cleaning mechanism for the water-soluble fertilizer rotary screen. During actual use of the cleaning mechanism, the sealing of the arc-shaped cavity 2 needs to be checked. Using the control panel, multiple sets of first solenoid valves 6 are closed, while the second solenoid valve 21 is opened and closed. When the air pump 3 draws air into the arc-shaped cavity 2, some air enters the air storage cylinder 18 through the air guide pipe 17. This air pushes the second piston 19 upwards. The second piston 19 can be connected to the connecting rod 20 and a set of lower limiting plates. 23. By compressing the telescopic spring 24 and using the scale markings, the specific position of the second piston 19 can be determined. At this time, the air pump 3 is stopped. When there is a leak in the arc-shaped cavity 2, the telescopic spring 24, under its own elastic force, can push the lower set of limiting plates 23 to move the connecting rod 20 and the second piston 19 downward. At this time, the scale markings can be used to determine whether the position of the second piston 19 has changed. When the second piston 19 is displaced, it indicates that there is a leak in the arc-shaped cavity 2. When the second piston 19 is not displaced, it indicates that there is no leak in the arc-shaped cavity 2. The right-angle frame 4 has an airtightness detection structure, which can detect whether the air storage space is a sealed structure, thus improving the practicality of the cleaning mechanism for the water-soluble fertilizer rolling screen.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
