A dust removal, bacteria spraying, and compost turning machine

Abstract

This invention relates to a dust removal, spraying, and turning machine, comprising a support plate. Two horizontally placed pipes are fixed to the lower end of the support plate. Each horizontal pipe has multiple vertically placed suction pipes fixed to its lower end. Each suction pipe has a filter plate fixed to its lower end. Each suction pipe has a spray pipe on its side, with its upper end connected to the horizontal pipe and its lower end located below the filter plate. All suction pipes can alternately draw air upwards and blow air downwards, with the airflow directions of adjacent suction pipes always opposite. The spray pipe corresponding to the downward-blowing suction pipe can simultaneously spray liquid bacteria downwards. This invention uses a baffle that moves left and right to continuously switch the position of the vertical holes between different vertical pipes on the same set of ventilation pipes, changing the airflow direction of adjacent sets of suction pipes and simultaneously spraying from adjacent sets of spray pipes. This ensures that the filter plate can be backflushed and cleaned in time before complete blockage, while also making the spraying of liquid bacteria more uniform.

Description

Technical Field

[0001] This invention relates to the field of compost turning machines, specifically a dust removal and bacteria spraying compost turning machine. Background Technology

[0002] To improve the quality of fertilizer fermentation, a compost turner is usually used to turn the fertilizer during the fermentation process. This can not only ensure that the fertilizer raw materials are mixed thoroughly and increase the aeration of the compost, but also reduce the internal temperature of the compost. However, a large amount of dust is generated during the turning process, causing air pollution. Therefore, a dust treatment device needs to be installed on the upper side of the compost turner to adsorb and filter the dust generated during the turning process.

[0003] CN212954912U discloses an organic fertilizer production device. This device uses multiple sets of dust suction pipes above the turning plate, and a blower to draw dust from the lower side of the pipes to a filter plate inside the dust collection box for filtration, thus reducing dust dispersion. However, this solution has the following drawbacks: 1. Fertilizer itself has a certain moisture and viscosity, and after entering the dust suction pipes with the air, it easily adheres to the pipe walls, making it difficult to clean. Prolonged operation can easily cause blockages in the suction pipes, reducing dust removal efficiency; 2. After dust enters the dust collection box with the air, the filter plate has a limited filtration area, making it difficult to clean after blockage, requiring regular filter replacement; 3. Existing turning machines cannot evenly spray liquid microbial inoculants inside the compost. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention adopts a dust removal and bacterial spraying turning machine, which solves the problem that the dust removal components of the turning machine are easily clogged by fertilizer and difficult to clean in the prior art.

[0005] The technical solution is a dust removal, spraying, and turning machine, comprising a horizontally placed support plate, with vertical plates fixed on the left and right sides of the lower end face of the support plate, and a rotating shaft rotatably connecting the two vertical plates. Multiple turning plates are fixed radially on the rotating shaft. Two horizontally placed tubes are fixed on the lower end face of the support plate, and multiple vertically placed dust suction pipes are fixed on the lower end face of each tube. A filter plate is fixed at the lower end of each dust suction pipe, and a spray pipe is provided on the side of each dust suction pipe. The upper end of the spray pipe is connected to the horizontal tube, and the lower end is located under the filter plate. All dust suction pipes can alternately draw air upward and blow air downward, and the airflow direction of two adjacent dust suction pipes is always opposite. The spray pipe corresponding to the dust suction pipe blowing air downward can spray liquid bacteria downward simultaneously.

[0006] All suction pipes on each horizontal tube are arranged at equal intervals and connected to the horizontal tube. A set of ventilation pipes connected to the horizontal tube is fixed above each suction pipe on the upper end face of each horizontal tube. Each set of ventilation pipes includes two vertical pipes, left and right, which can respectively draw air into the horizontal tube and blow air into the horizontal tube. A slider that can move left and right is set above each suction pipe in the horizontal tube. All sliders are fixedly connected to each other by a connecting rod and always move left and right in sync. A vertical hole is opened in the middle of the slider. When the slider moves to the left or right to one end, it can block one of the vertical pipes of the ventilation pipe, allowing the other vertical pipe to connect to the suction pipe through the vertical hole. The airflow direction in the vertical pipes connected to the corresponding suction pipes in two adjacent sets of ventilation pipes is opposite. When the slider moves to the other end, the slider releases the blockage of one vertical pipe while blocking the other vertical pipe. When the slider moves left and right, the slider always blocks the connection port between the side spray pipe of the suction pipe and the horizontal tube.

[0007] A ventilation box is fixed in the middle of the upper surface of the support plate, and a filter screen is fixed in the middle of the ventilation box. The filter screen divides the ventilation box cavity into left and right parts. Air outlet and air inlet are respectively opened at the left and right ends of the ventilation box. A fan is installed in the left cavity of the ventilation box, and the fan outlet pipe is connected to the air outlet. Two air pipes, a total of four, are fixed above each horizontal pipe on the upper surface of the support plate. Each air pipe is connected to the vertical pipe at the opposite position on the adjacent ventilation pipe on the corresponding side. Two air pipes connected to the vertical pipes on the front and rear ventilation pipes in the same way are connected to the air outlet and air inlet on the ventilation box through a T-junction, as shown in the attached figure.

[0008] A liquid supply tank is fixed on the left side of the upper end face of the support plate. The liquid supply tank is connected to the horizontal pipes on the front and rear sides through a three-way pipe, as shown in the attached figure. A water pump is installed in the liquid supply tank, which can continuously pump liquid into the horizontal pipe. The two adjacent spray pipes on the lower side of each horizontal pipe are located on the left and right sides of the corresponding suction pipe. When the slider is in the left position, it can block only the connection between the spray pipe on the left side of the suction pipe and the horizontal pipe. When the slider is in the right position, it can block only the connection between the spray pipe on the right side of the suction pipe and the horizontal pipe. Each slider is provided with a horizontal hole that penetrates the left and right end faces.

[0009] The lower end of the suction pipe is fixed with a dust collection hood, which is a funnel-shaped shell with a lower opening larger than the upper opening. The lower end of the spray pipe penetrates the side wall of the dust collection hood and is fixedly connected with an atomizing nozzle.

[0010] Each leftmost slider has a horizontal bar fixed to its left end. The left end of the horizontal bar passes through the left end face of the horizontal tube and can move left and right. The left end of the left vertical plate is provided with a front and rear baffle. The baffle is fixedly connected to the front and rear horizontal bars. A compression spring is fixed between the baffle and the left vertical plate. The compression spring always gives the baffle a leftward pushing force. A motor is fixed on the left vertical plate. The motor shaft faces upward and a cam is fixed on the shaft. The right end of the cam contacts the baffle. When the cam rotates with the motor, it can drive the baffle to move back and forth left and right.

[0011] Two baffles are fixed between the two vertical plates, one in front and one behind. The two baffles are placed at an angle with their lower ends gradually moving away from each other. The baffles can prevent the material from being thrown upward by the flipping plate.

[0012] The present invention has the following advantages over the prior art:

[0013] 1. The dust suction pipe of the exhaust operation can suck in the dust raised by the turning plate, filter it through the filter plate and then draw it into the exhaust box to avoid dust clogging the exhaust pipe.

[0014] 2. After being filtered through the filter screen inside the air box, the air re-enters the blower. The secondary filtration further ensures the circulation of air driven by the blower. The dust suction pipe of the blowing operation can back-blow the filter plate, causing the blockage on the filter plate to be blown off onto the compost, preventing excessive blockage on the filter plate from affecting the blower's air extraction volume and the filter plate's filtration efficiency.

[0015] 3. The liquid bacteria in the supply tank enters the horizontal pipe under the action of the water pump, fills the entire horizontal hole on the slider, and then sprays downward through the corresponding spray pipe of the dust suction pipe of the air blowing operation. While spraying the compost with bacteria evenly, it can also wet the blockage blown down by the dust suction pipe of the air blowing operation, and prevent the blockage blown down by the air blowing operation from being sucked back into the adjacent dust suction pipe that is currently pumping air.

[0016] 4. During the turning and spraying process of this device, the motor drives the baffle to move back and forth left and right through the cooperation of the cam and the compression spring. This causes all the sliders to move left and right in the horizontal tube, so that the position of the vertical hole is constantly switched between different vertical tubes on the same set of ventilation pipes. This causes the two adjacent sets of dust suction pipes to constantly change the airflow direction, and at the same time, the two adjacent sets of spray pipes spray the compost in succession. This ensures that the filter plate can be back-blown and cleaned in time before it is completely blocked. At the same time, it makes the liquid bacteria spray more even and greatly improves the compost fermentation efficiency. Attached Figure Description

[0024] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Depend on Figures 1 to 5 The present invention includes a horizontally placed support plate 1, with vertical plates 2 fixed on the left and right sides of the lower end face of the support plate 1, and a rotating shaft 3 rotatably connected between the two vertical plates 2. Multiple flipping plates 4 are fixed radially on the rotating shaft 3. Two horizontally placed horizontal pipes 5 are fixed on the lower end face of the support plate 1. Multiple vertically placed suction pipes 6 are fixed on the lower end face of each horizontal pipe 5. A filter plate 7 is fixed at the lower end of each suction pipe 6. A spray pipe 8 is provided on the side of each suction pipe 6. The upper end of the spray pipe 8 is connected to the horizontal pipe 5, and the lower end is located below the filter plate 7. All suction pipes 6 can alternately draw air upward and blow air downward, and the airflow direction of two adjacent suction pipes 6 is always opposite. The spray pipe 8 corresponding to the suction pipe 6 blowing air downward can spray liquid bacteria downward at the same time.

[0026] All suction pipes 6 on each horizontal pipe 5 are arranged at equal intervals and connected to the horizontal pipe 5. A set of ventilation pipes 9 connected to the horizontal pipe 5 is fixed above each suction pipe 6 on the upper end face of each horizontal pipe 5. Each set of ventilation pipes 9 includes two vertical pipes 10 on the left and right. The two vertical pipes 10 can respectively draw air into the horizontal pipe 5 and blow air into it. A slider 11 that can move left and right is respectively installed above each suction pipe 6 in the horizontal pipe 5. All sliders 11 are fixedly connected to each other by connecting rods and always keep moving left and right in sync. A vertical hole is opened in the middle of the slider 11. 12. When slider 11 moves to one end to the left or right, it can block one of the vertical pipes 10 of the ventilation pipe 9, so that the other vertical pipe 10 is connected to the suction pipe 6 through the vertical hole 12. The airflow direction in the vertical pipes 10 connected to the corresponding suction pipe 6 in the two adjacent sets of ventilation pipes 9 is opposite. When slider 11 moves to the other end, slider 11 releases the blockage of one vertical pipe 10 while blocking the other vertical pipe 10. When slider 11 moves left and right, slider 11 always blocks the connection between the side spray pipe 8 and the horizontal pipe 5 of the suction pipe 6.

[0027] A fume extraction box 13 is fixed to the middle of the upper surface of the support plate 1. A filter screen 14 is fixed to the middle of the fume extraction box 13, dividing the cavity of the fume extraction box 13 into left and right parts. Air outlets 15 and air inlets 16 are respectively opened at the left and right ends of the fume extraction box 13. A fan 17 is installed in the left cavity of the fume extraction box 13, and the air outlet pipe of the fan 17 is connected to the air outlet 15. Two air pipes 18 are fixed above each horizontal pipe 5 on the upper surface of the support plate 1. Each air pipe 18 is connected to a vertical pipe 10 at the opposite position on the adjacent ventilation pipe 9 on the corresponding side. Two air pipes 18 connected in the same way to the vertical pipes 10 on the ventilation pipes 9 on the front and rear sides are connected to the air outlets 15 and air inlets 16 on the fume extraction box 13 via T-junctions, as shown in the attached diagram. Figure 3 As shown.

[0028] A liquid supply tank 19 is fixed to the left side of the upper end face of the support plate 1. The liquid supply tank 19 is connected to the horizontal pipes 5 on the front and rear sides respectively through a three-way pipe, as shown in the attached figure. Figure 3 As shown, a water pump is installed in the liquid supply tank 19, which can continuously pump liquid into the horizontal pipe 5. The two adjacent spray pipes 8 on the lower side of each horizontal pipe 5 are located on the left and right sides of the corresponding suction pipe 6. When the slider 11 is in the left position, it can block only the connection between the spray pipe 8 on the left side of the suction pipe 6 and the horizontal pipe 5. When the slider 11 is in the right position, it can block only the connection between the spray pipe 8 on the right side of the suction pipe 6 and the horizontal pipe 5. Each slider 11 is provided with a horizontal hole 20 that penetrates the left and right end faces.

[0029] The dust collection pipe 6 is fixed to a dust collection hood 21 at its lower end. The dust collection hood 21 is a funnel-shaped shell with a lower opening larger than the upper opening. The lower end of the spray pipe 6 penetrates the side wall of the dust collection hood 21 and is fixedly connected to an atomizing nozzle 22.

[0030] Each leftmost slider 11 has a horizontal bar 23 fixed to its left end. The left end of the horizontal bar 23 passes through the left end face of the horizontal tube 5 and can move left and right. The left end of the left vertical plate 2 is provided with a front and rear baffle 24. The baffle 24 is fixedly connected to the front and rear horizontal bars 23. A compression spring is fixed between the baffle 24 and the left vertical plate 2. The compression spring always gives the baffle 24 a leftward pushing force. A motor 25 is fixed on the left vertical plate 2. The shaft of the motor 25 faces upward and a cam 26 is fixed on the shaft. The right end of the cam 26 contacts the baffle 24. When the cam 26 rotates with the motor 25, it can drive the baffle 24 to move back and forth left and right.

[0031] Two baffle plates 27 are fixed between the two vertical plates 2 respectively. The two baffle plates 27 are placed at an angle with their lower ends gradually moving away from each other. The baffle plates 27 can prevent the material from being thrown upward by the flipping plate 4.

[0032] It is worth mentioning that the positions of the two vertical pipes 10 on the front and rear ventilation pipes 9 are completely opposite, ensuring that when the sliders 11 in the front and rear horizontal pipes 5 move left and right in sync, the airflow direction in the corresponding positions of the suction pipes 6 on the front and rear sides is opposite, and the spraying areas of the spray pipes 8 on the front and rear sides are complementary.

[0033] In use, the present invention first fills the liquid inoculum tank 19 with liquid bacteria, then starts the compost turner, causing the rotating shaft 3 to turn the compost through the turning plate 4. The blower 17 blows and draws air into the air pipe 18 through the exhaust box 13 via the exhaust port 15 and the intake port 16. Since each air pipe 18 is connected to the vertical pipe 10 at the opposite position on the adjacent air exchange pipe 9 on the corresponding side, the airflow directions of the two adjacent dust suction pipes 6 are always opposite. The dust suction pipe 6 can suck in the dust raised by the turning plate 4, filter it through the filter plate 7, and then draw it into the exhaust box 13 to avoid dust clogging the exhaust pipe. After being filtered by the filter screen 14 in the exhaust box 13, it re-enters the blower 17. The secondary filtration further ensures the circulation of the airflow driven by the blower. Dust pipe 6 can backflush the filter plate 7, causing the blockage on the filter plate 7 to be blown off onto the compost, preventing excessive blockage on the filter plate 7 from affecting the air extraction volume of the blower and the filtration efficiency of the filter plate 7; since the slider 11 is located at one end of the blocked air blowing vertical hole 10, it also blocks the connection between the spray pipe 8 and the horizontal pipe 5. Therefore, the liquid bacteria in the liquid supply tank 19 enters the horizontal pipe 5 under the action of the water pump, fills the entire horizontal hole 20 on the slider 11, and then sprays downward through the spray pipe 8 corresponding to the dust suction pipe 6 of the air blowing operation. While uniformly spraying the compost with bacteria, it can also humidify the blockage blown down by the dust suction pipe 6 of the air blowing operation, preventing the blockage blown down by the air blowing operation from being sucked back into the adjacent dust suction pipe 6 that is currently in the air extraction operation.

[0034] During the turning and spraying process of this device, the motor 25 drives the baffle 24 to move back and forth left and right through the cooperation of the cam 26 and the compression spring, so that all the sliders 11 move left and right in the horizontal tube 5. This allows the position of the vertical hole 12 to switch back and forth between different vertical tubes 10 on the same set of ventilation pipes 9, so that the two adjacent sets of dust suction pipes 6 continuously change the airflow direction. At the same time, the two adjacent sets of spray pipes 8 spray the compost in succession, ensuring that the filter plate 7 can be back-blown and cleaned in time before it is completely blocked. This also makes the liquid bacteria spray more even, greatly improving the compost fermentation efficiency.
