Description

Technical Field

[0001] The utility model belongs to the field of drying mechanisms, and more specifically, particularly relates to a drying mechanism for bag dust removal. Background Art

[0002] The bag filter inputs dust gas. Dust with large particles and high specific gravity will first settle in the ash hopper by gravity. The gas is guided to be transported online through the space restriction, and the dust is intercepted by the bag. The filtered gas is continuously output upward to the clean air chamber and discharged through the clean air outlet.

[0003] Based on the above, the inventor of the utility model found that the existing drying mechanism for bag dust removal has the following main shortcomings, such as:

[0004] In order to prevent the moisture in the dust from adhering to the bag, the equipment is equipped with a device for drying through heating. However, in order to dry the moisture in the internal dust, the temperature difference between the heating area and the upper and lower connection points is large, and it is easy to form water droplets at the low temperature position to adhere to the dust.

[0005] Therefore, it is necessary to propose a drying mechanism for bag dust removal. Utility Model Content

[0006] In order to solve the problem that when the above technology is used to dry the moisture of the internal dust, the temperature difference between the heating area and the upper and lower connecting parts is large, and it is easy to form water droplets at the low temperature position to adhere to the dust.

[0007] The purpose and effect of the drying mechanism for bag dust removal in the utility model are achieved by the following specific technical means:

[0008] Its structure includes a dust gas inlet, a controller, a main filter grid, an air bag, an electromagnetic pulse valve, a clean air outlet, a venturi, a cloth bag, a drying mechanism, and an ash hopper. The dust gas inlet is connected to the ash hopper. The controller controls the air bag and the drying mechanism through the system. The cloth bag is placed inside the main filter grid. The electromagnetic pulse valve is connected between the air bag and the venturi to play a connecting role. The cloth bag is connected and suspended below the venturi. The clean air outlet is connected to the dust gas inlet through the main filter grid. The drying mechanism is installed inside the main filter grid and below the cloth bag.

[0009] The drying mechanism includes a temperature conducting ring, a connecting port, a constant temperature rod, and a movable block. The constant temperature rod vertically penetrates the interior of the drying mechanism. The connecting port is connected to the side of the temperature conducting ring. The movable block is installed on the top of the constant temperature rod. When dust passes through the drying mechanism, the drying mechanism can continuously maintain a gradual temperature change inside to dry the water vapor in the dust without a large temperature span. The drying mechanism is located at a position where the dust just contacts the bag, so the bag can be continuously kept dry and the moisture in the dust can be quickly absorbed and dried.

[0010] As a further improvement of the present invention, the constant temperature rod and the temperature conducting ring are placed inside the main filter grid to play a role in constant temperature regulation. The temperature is highest at the part closest to the temperature conducting ring, and the temperature will gradually decrease as it is farther away, forming a temperature gradient effect on the internal space. The heat derived by the constant temperature rod from the constant temperature conducting ring is highest at the part in contact with the temperature conducting ring, and the temperature becomes lower as it moves to both sides, so that the air inside the main filter grid forms a gradual temperature. Four constant temperature rods are provided and are evenly distributed in a circular shape.

[0011] As a further improvement of the utility model, the movable block includes an extension cover, a pendulum block, a limit rail, a fixed body, an arc layer, a connecting block, and a rotating ball. The extension cover is fixed to the lower surface of the pendulum block. The pendulum block is engaged in the limit rail through the connecting block to move. The extension cover is against the upper end surface of the thermostatic rod. When the extension cover loses the thrust of the gas, it will swing down due to gravity and impact the surface of the thermostatic rod, allowing the dust attached to the surface to fall off.

[0012] As a further improvement of the utility model, four pendulum blocks are provided and evenly distributed in a circular shape, and the lower surface of the arc layer is an arc structure, which can better withstand the push of the gas and drive the pendulum block to swing upward along the limit rail, and the connecting block drives the pendulum block to be fixed to the rotating ball to assist in rotation.

[0013] As a further improvement of the utility model, the constant temperature rod includes a cone head, a temperature conductor, a constant temperature core, a hollow space, an insulation layer, and a buffer body. The cone head is fixed at the lower end of the insulation layer, the buffer body is stuck between the constant temperature core and the insulation layer, the temperature conductor is connected to the temperature through the constant temperature core, the temperature of the constant temperature core becomes lower and lower as it moves toward both sides of the temperature conductor, the insulation layer conducts the internal temperature of the hollow space to the outside and is thinner and supported by the buffer body inside, and the temperature conductor is a symmetrical structure that passes through the constant temperature core and is connected to the temperature conductor ring.

[0014] As a further improvement of the utility model, when the upper end swing block swings down and impacts, the insulation layer can shake slightly due to its thin thickness, thereby vibrating and removing the attached dust, and the buffer body supports the shape of the insulation layer and buffers the impact force.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. First, start the drying mechanism through the controller to adjust the internal temperature to a constant temperature. The position of the temperature guide ring is the highest point of the constant temperature. The constant temperature rod connected to the temperature guide ring will extend the temperature of the temperature guide ring. The farther away from the temperature guide ring, the lower the temperature around it, so that the temperature inside the main filter grid forms a gradual change. The gas is filtered through the bag. When the gas stops being transported, the pendulum will swing downward by its own gravity, causing a slight vibration to it, so that the dust attached to the surface can fall off, avoiding affecting the subsequent thermal conductivity and constant temperature effect. The bag is a breathable cloth. When the electromagnetic pulse valve is processed, the internal gas will be processed together with the drying mechanism placed on the side of the bag. Further cleaning of the dust on the surface of the drying mechanism, when the gas enters, the internal air can be dried and adjusted from low to high, and then from high to low, so that the gas is in a dry state when filtered, and there will be no large temperature difference during input and output to form water droplets, and the dust on the surface of the constant temperature rod can be processed to avoid affecting the subsequent constant temperature and thermal conductivity effect.

[0017] 2. The temperature is transmitted to the outside by the thermal insulation layer, so that the temperature inside the main filter is gradually changed. When the gas input pushes the movable block to swing open and hits the constant temperature rod, the thermal insulation layer can vibrate slightly after the movable block hits the top, which helps to remove the dust on the surface. When the movable block returns to its position and hits itself slightly, the thin material on its surface can vibrate to assist in the removal of dust. When the dust is cleaned together with the cloth bag, the dust on the surface of the thermal insulation layer can be further cleaned together. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] Embodiment 1:

[0026] As attached Figure 1 To Attachment Figure 4 As shown:

[0027] The utility model provides a drying mechanism for bag dust removal, which structure includes a dust gas inlet 1, a controller 2, a main filter grid 3, an air bag 4, an electromagnetic pulse valve 5, a clean air outlet 6, a venturi 7, a bag 8, a drying mechanism 9, and an ash hopper 10. The dust gas inlet 1 is connected to the ash hopper 10, the controller 2 controls the air bag 4 and the drying mechanism 9 through the system, the bag 8 is placed inside the main filter grid 3, the electromagnetic pulse valve 5 is connected between the air bag 4 and the venturi 7 to play a connecting role, the bag 8 is connected and suspended below the venturi 7, the clean air outlet 6 is connected to the dust gas inlet 1 through the main filter grid 3, and the drying mechanism 9 is installed inside the main filter grid 3 and below the bag 8;

[0028] The drying mechanism 9 includes a temperature conducting ring a1, a connecting port a2, a constant temperature rod a3, and a movable block a4. The constant temperature rod a3 vertically penetrates the interior of the drying mechanism 9. The connecting port a2 is connected to the side of the temperature conducting ring a1. The movable block a4 is installed on the top of the constant temperature rod a3. When dust passes through the drying mechanism 9, it can continuously maintain a gradual temperature change inside to dry the water vapor in the dust without a large temperature span. The position of the drying mechanism 9 is the position where the dust just contacts the cloth bag 8. The cloth bag 8 can be continuously kept dry and the moisture in the dust can be quickly absorbed and dried. The constant temperature rod a3 is connected to the temperature of the temperature conducting ring a1.

[0029] Among them, the constant temperature rod a3 and the temperature conducting ring a1 are placed inside the main filter grid 3 to play a role in constant temperature regulation. The part closest to the temperature conducting ring a1 has the highest temperature, and the temperature will gradually decrease as it is farther away, forming a temperature gradient effect on the internal space. The heat derived by the constant temperature rod a3 from the constant temperature temperature conducting ring a1 is at the highest temperature at the part in contact with the temperature conducting ring a1, and the temperature becomes lower as it moves to both sides, so that the air inside the main filter grid 3 forms a gradual temperature. The constant temperature rod a3 is provided with four and is circular and uniform. The controller 2 is connected to control the temperature conducting ring a1 through the connection port a2.

[0030] Among them, the movable block a4 includes an extension cover w1, a pendulum block w2, a limit rail w3, a fixed body w4, an arc layer w5, a connecting block w6, and a rotating ball w7. The extension cover w1 is fixed to the lower surface of the pendulum block w2. The pendulum block w2 is inserted into the limit rail w3 through the connecting block w6 to move. The extension cover w1 is against the upper end surface of the thermostatic rod a3. When the extension cover w1 loses the thrust of the gas, it will swing down along the gravity to impact the surface of the thermostatic rod a3, allowing the dust attached to the surface to fall off. The extension cover w1 and the pendulum block w2 are divided into four parts, which can withstand the thrust of the gas in sections.

[0031] Among them, there are four swing blocks w2 and they are evenly distributed in a circle. The lower surface of the arc layer w5 is an arc structure, which can better withstand the push of the gas and drive the swing block w2 to swing upward along the limit rail w3. The connecting block w6 drives the swing block w2 and the rotating ball w7 to be fixed and assist in rotation. The arc layer w5 is attached to the lower surface of the extension cover w1.

[0032] In the utility model, when it is necessary to process the dust gas, the controller 2 is first used to start the drying mechanism 9 to adjust the internal temperature to a constant temperature. The position of the temperature conducting ring a1 is the highest constant temperature. The constant temperature rod a3 connected to the temperature conducting ring a1 will extend the temperature of the temperature conducting ring a1. The farther away from the temperature conducting ring a1, the lower the temperature around it will be, so that the temperature inside the main filter grid 3 forms a gradual change. The constant temperature rod a3 also keeps the temperature of each layer constant. When the dust gas is input through the dust gas inlet 1, the dust with large particles and high specific gravity will first settle in the ash hopper 10 by gravity, and the gas will move to the upper end by the guidance of the space. The dust gas is transported upward from the low temperature to the high temperature. After the drying process, the farther away from the temperature conducting ring a1, the temperature will gradually decrease and become constant. The gas is filtered through the cloth bag 8, and the gas that passes through is output from the clean gas outlet 6 from the upper end. When the gas passes through the temperature conducting ring a1, it will exert a driving force on the constant temperature rod a3, and the arc layer w5 will bear the wrapping driving force. The pendulum block w2 will rotate along the limit rail w3 through the connecting block w6, so that the pendulum block w2 can be in an expanded state. When the gas stops being transported, the pendulum block w2 will swing downward by its own gravity, and the extension cover w1 will hit the constant temperature rod a3, causing it to vibrate slightly, so that the dust attached to the surface can fall off, avoiding affecting the subsequent thermal conductivity and constant temperature effect. When the gas is filtered, the air bag 4 will spray and clean the dust on the surface of the cloth bag 8 through the electromagnetic pulse valve 5, and the dust will fall into the ash hopper 10. The cloth bag 8 is a breathable cloth. When the electromagnetic pulse valve 5 is processed, the internal gas will be processed together with the drying mechanism 9 placed on the side of the cloth bag 8 to further clean the dust on the surface of the drying mechanism 9.

[0033] Embodiment 2:

[0034] As attached Figure 5 As shown:

[0035] Among them, the constant temperature rod a3 includes a cone head g1, a temperature conductor g2, a constant temperature core g3, a middle space g4, an insulation layer g5, and a buffer body g6. The cone head g1 is fixed at the lower end of the insulation layer g5, and the buffer body g6 is stuck between the constant temperature core g3 and the insulation layer g5. The temperature conductor g2 is connected to the temperature through the constant temperature core g3. The temperature of the constant temperature core g3 is located on the temperature conductor g2, and the temperature becomes lower and lower as it moves toward both sides. The insulation layer g5 conducts the internal temperature of the middle space g4 to the outside and is thinner and supported by the buffer body g6 inside. The temperature conductor g2 is a symmetrical structure that passes through the constant temperature core g3 and is connected to the temperature conductor ring a1. Three buffer bodies g6 are provided.

[0036] When the thermal insulation layer g5 hits the upper end swing block w2, it can shake slightly due to its thin thickness, thereby vibrating and removing the attached dust. The buffer body g6 supports the shape of the thermal insulation layer g5 and buffers the impact force. The cone head g1 is a cone structure to assist in the removal of dust.

[0037] The specific usage and function of this embodiment are as follows:

[0038] In the utility model, when the temperature-conducting ring a1 conducts heat through the constant temperature rod a3, the temperature-conducting body g2 of the constant temperature rod a3 is inserted into the temperature-conducting ring a1 to receive and conduct energy, and the constant temperature core g3 is used to expand outward. The temperature near the temperature-conducting body g2 is higher, and the temperature is lower as it goes outward. The temperature is transmitted outward by the thermal insulation layer g5, so that the temperature inside the main filter grid 3 is gradually changed. When the gas input pushes the movable block a4 to swing open and then hits the constant temperature rod a3, the thickness of the thermal insulation layer g5 itself is relatively thin and the movable block a4 inside is an empty part. After the movable block a4 is located at the top and hits, the thermal insulation layer g5 can produce a slight vibration, which can cause the dust on the surface to fall off. The shape and buffering of the thermal insulation layer g5 are supported by the buffer body g6 inside.

[0039] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
