Technical Field

[0001] This utility model belongs to the field of collection device technology, and more specifically, it relates to a waste incineration fly ash collection device. Background Technology

[0002] With the acceleration of urbanization, municipal solid waste incineration power generation technology has been widely used due to its advantages of volume reduction and resource utilization. However, the fly ash generated during the incineration process causes serious environmental pollution. The collection and disposal of fly ash is directly related to environmental pollution control and the operating efficiency of the incineration system. In the existing technology, fly ash is mostly collected by bag filter dust collectors and then transferred to ton bags for temporary storage via pneumatic conveying system. However, this transfer process is prone to dust generation, and the filter screen at the fan needs to be replaced frequently. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a waste incineration fly ash collection device, which solves the technical problems of high filter replacement frequency at the blower of traditional collection devices and the generation of a lot of dust during fly ash transfer after the collection process is completed.

[0004] The purpose and effectiveness of this utility model's fly ash collection device for waste incineration are achieved through the following specific technical means:

[0005] A waste incineration fly ash collection device includes an outer shell, a collection chamber inside the outer shell, two sets of air inlets on both sides of the collection chamber, a first filter screen on one side of each set of air inlets, two sets of vibration modules at both ends of each set of air inlets, a top cover on the top of the outer shell, a hydraulic press at the bottom of the outer shell, two sets of weighing plates symmetrically arranged at the bottom of the collection chamber, and a control module at one end of the outer shell.

[0007] According to a preferred embodiment, two sets of limiting grooves are respectively provided on the top of the two sets of air outlets, and a second filter screen is installed in each of the two sets of limiting grooves. Two sets of centrifugal fans are respectively provided on one side of the two sets of air outlets.

[0008] According to a preferred embodiment, two sets of mounting cavities are respectively provided on both sides of the outer shell, and multiple sets of electric telescopic rods are provided at both ends of the two sets of mounting cavities. Multiple sets of electric telescopic rods are connected to one side of the two sets of weighing plates, and multiple sets of vibration motors are provided on one side of the two sets of mounting cavities.

[0009] According to a preferred embodiment, a water pipe groove is provided at one end of the outer shell, and a water pipe is inserted through the water pipe groove. A solenoid valve is provided at one end of the water pipe, and a water spray head is provided at the bottom of the water pipe. The water spray head contacts the top surface of the compression chamber. A diversion pipe is provided on the water pipe, and two sets of fixing grooves are provided at the bottom of the mounting cavity. The bottom of the water pipe is inserted into the two sets of fixing grooves.

[0010] According to a preferred embodiment, each of the two sets of mounting cavities is provided with a maintenance plate on one side, and each of the two sets of maintenance plates is provided with four sets of hinges at the bottom, the bottom of each of the four sets of hinges being connected to the outer shell. Each of the two sets of maintenance plates is provided with four sets of latches at the top, the top of each of the four sets of latches being connected to the outer shell.

[0011] According to a preferred embodiment, the top cover is provided with an ash inlet, the bottom cover is provided with a limiting guide rail, the top of the outer shell is provided with a limiting groove, the limiting guide rail passes through the limiting groove, and the top of the outer shell is provided with a sealing ring.

[0012] According to a preferred embodiment, the bottom of the outer casing is provided with a discharge port, and the top of the discharge port is provided with a pull plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Two sets of centrifugal fans operate alternately. When one set of fans is running, the other set stops. The vibration module at the air outlet on the same side as the fan starts working, shaking off the fly ash adsorbed on the first filter screen, reducing the frequency of manual filter screen replacement and improving convenience. A second filter screen is installed at the air outlet to further reduce fly ash entering the centrifugal fan and causing damage to the centrifugal fan, thus improving the reliability of the device.

[0015] 2. When the fly ash accumulated on the weighing plate reaches the set weight, multiple sets of electric telescopic rods drive the two sets of weighing plates to move horizontally, causing the accumulated fly ash to fall into the compression chamber. Then, the multiple sets of electric telescopic rods drive the two sets of weighing plates to return to their original position. At this time, the solenoid valve connected to the water pipe opens, and the water spray head at the bottom of the water pipe begins to spray water. After the fly ash absorbs water, it can reduce the dust generated during transportation. Then, the hydraulic press squeezes the pressure plate to one side of the compression chamber, squeezing the water-absorbed fly ash into blocks, which facilitates the transportation of fly ash. Squeezing into blocks further reduces the dust generated during transportation and reduces environmental pollution. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides a waste incineration fly ash collection device, including a housing 100, a collection chamber 101 inside the housing 100, two sets of air vents 102 on both sides of the collection chamber 101, and a first filter screen 103 on one side of each of the two sets of air vents 102. The first filter screen 103 can effectively isolate fly ash and prevent fly ash from entering the centrifugal fan 115 and causing damage to the device. Two sets of vibration modules 104 are provided at both ends of the two sets of air vents 102. The vibration modules 104 can shake off the fly ash attached to the first filter screen 103, reducing the frequency of manual filter screen replacement. A top cover 105 is provided on the top of the housing 100, a hydraulic press 106 is provided on the bottom of the housing 100, two sets of weighing plates 107 are symmetrically arranged at the bottom of the collection chamber 101, and a control module 108 is provided at one end of the housing 100. The control module 108 can be an STM32H503RBT6 model.

[0028] The bottom of the outer casing 100 is provided with a mounting groove 109, and a mounting base 110 is provided in the mounting groove 109. A hydraulic press 106 is provided on the mounting base 110. A connector 111 is provided on one side of the hydraulic press 106, and a slot is provided on one side of the connector 111. The hydraulic press 106 is locked in the slot. A pressure plate 112 is provided on one side of the connector 111, and a compression chamber 113 is provided on one side of the pressure plate 112. When fly ash falls into the compression chamber 113, the user can control the hydraulic press 106 to start through the control module 108. The hydraulic press 106 drives the pressure plate 112 to move towards the compression chamber 113 through the connector 111. The pressure plate 112 compresses the fly ash into blocks, which facilitates the transportation and further processing of the fly ash.

[0029] Two sets of limiting grooves are respectively provided on the top of the two sets of air outlets 102, and a second filter screen 114 is installed in each of the two sets of limiting grooves. Two sets of centrifugal fans 115 are respectively provided on one side of the two sets of air outlets 102. The control module 108 can control the start and stop of the two sets of centrifugal fans 115. The centrifugal fans 115 draw out the air in the collection chamber 101, so that the collection chamber 101 forms a negative pressure. The fly ash in the incineration device connected by the pipeline will be sucked into the collection chamber 101. The double filtration of the first filter screen 103 and the second filter screen 114 can effectively prevent fly ash from being sucked into the centrifugal fans 115, reducing the possibility of shutdown due to device failure.

[0030] Two sets of mounting cavities 116 are respectively provided on both sides of the outer casing 100. Multiple sets of electric telescopic rods 117 are provided at both ends of the two sets of mounting cavities 116. Multiple sets of electric telescopic rods 117 are connected to one side of the two sets of weighing plates 107. The weighing plate 107 contains a weight sensor (not shown in the figure) to weigh the fly ash accumulated on the weighing plate 107. The weighing plate 107 and the multiple sets of electric telescopic rods 117 are electrically connected to the control module 108. When the weight of the fly ash accumulated on the weighing plate 107 reaches the threshold, the control module 108 can control the multiple sets of electric telescopic rods 117 to start. The multiple sets of electric telescopic rods 117 drive the two sets of weighing plates 107 to move to both sides, and the fly ash can fall into the compression chamber 113. Multiple sets of vibration motors 118 are provided on one side of the two sets of mounting cavities 116. The multiple sets of vibration motors 118 can cause the fly ash attached to the collection chamber 101 to fall off and accumulate on the weighing plate 107.

[0031] A water pipe groove is provided at one end of the outer casing 100, and a water pipe 119 is installed in the water pipe groove. A solenoid valve 130 is provided at one end of the water pipe 119, and a water spray head 120 is provided at the bottom of the water pipe 119. The water spray head 120 contacts the top surface of the compression chamber 113. A diversion pipe 121 is provided on the water pipe 119. Two sets of fixing grooves 122 are provided at the bottom of the mounting cavity 116. The bottom of the water pipe 119 passes through the two sets of fixing grooves 122. When the fly ash enters the compression chamber 113, the control module 108 can control the solenoid valve 130 to open. Water enters the compression chamber 113 through the water spray head 120 and mixes with the fly ash. After the fly ash absorbs water, the dust generated during transportation is reduced. Then, the hydraulic press 106 drives the pressure plate 112 to squeeze the fly ash into blocks, further reducing the dust generated during transportation and reducing environmental pollution.

[0032] Each of the two sets of mounting cavities 116 has a maintenance plate 123 on one side. The bottom of each of the two sets of maintenance plates 123 is provided with four sets of hinges 124, and the bottom of each of the four sets of hinges 124 is connected to the outer shell 100. The top of each of the two sets of maintenance plates 123 is provided with four sets of latches 125, and the top of each of the four sets of latches 125 is connected to the outer shell 100.
