Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust removal equipment for the production of a polyurethane waterproof composite material that can be quickly cured. Background Art
[0002] Polyurethane waterproof coating is a prepolymer containing isocyanate groups formed by the addition polymerization reaction of isocyanate, polyether, etc., and is formulated with catalysts, anhydrous auxiliaries, anhydrous fillers, solvents, etc. through processes such as mixing to produce a one-component polyurethane waterproof coating. This type of coating is a reaction-curing type (moisture-curing) coating and has characteristics such as high strength, large elongation, and good water resistance.
[0003] When producing polyurethane waterproof coating, most use stirring equipment to perform long-term stirring operations on the raw materials of the coating. However, during the stirring period, due to the long time consumption, dust in the air easily drifts into the raw materials, and thus dust with larger particles will affect the overall production quality of the delicate coating. Therefore, a dust removal device is required to perform dust removal operations on the air above the stirring equipment. Currently, the existing dust removal equipment needs to clean the filter screen regularly, and due to the large amount of dust in the production workshop, the filter screen needs to be repeatedly cleaned in a short time. Summary of the Invention
[0004] The technical problem that the utility model needs to solve is to provide a dust removal equipment for the production of a polyurethane waterproof composite material that can be quickly cured to solve the above problems.
[0005] The technical solution of the utility model to solve the above technical problems is: a dust removal equipment for the production of a polyurethane waterproof composite material that can be quickly cured, including a fixing plate, a box body is connected to the right side of the fixing plate, an air chamber is arranged inside the box body, a blower is arranged above the air chamber, an exhaust port is arranged above the blower, a rolling door mechanism is arranged below the air chamber, the right side of the rolling door mechanism is connected to a telescopic rod, a filter screen mechanism is arranged below the rolling door mechanism, the filter screen mechanism includes a movable frame, a first filter screen is installed inside the movable frame, a high-frequency vibrator is installed at the bottom side of the movable frame, sliding grooves are opened at the bottom ends of both sides of the box body, the sliding grooves are connected to the connecting blocks on the collection box through sliders, an electrostatic emitter is installed at the bottom side of the collection box, and electric grilles are arranged on both sides of the box body.
[0006] As a preferred technical solution of the utility model, a second filter screen is installed inside the air chamber near the blower side, and the inner side of the second filter screen is connected to the inner wall of the box body through a slot.
[0007] As a preferred technical solution of the utility model, the position of the electric grille is adapted to the position of the first filter screen.
[0008] As a preferred technical solution of the present utility model, the shape of the first filter screen is a "T" shape.
[0009] As a preferred technical solution of the present utility model, an electric check shutter is provided outside the electric grille.
[0010] As a preferred technical solution of the present utility model, the electric grille is divided into two rows and arranged at equal intervals.
[0011] Since the present utility model adopts such a structure, the operation of the rolling door mechanism causes the curtain sheets of the rolling door mechanism to separate the box body. When the high-frequency vibrator is turned on, the dust on the first filter screen falls. When the electrostatic emitter is turned on, all the floating dust is adsorbed into the collection box, achieving the effect of collecting dust and also achieving the effect of cleaning the filter screen, avoiding the work of repeatedly cleaning the filter screen, saving time and effort, being convenient and efficient to use, and having good practicability.

Detailed Embodiments
[0017] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0018] Such as Figures 1 to 4As shown in the figure, a dust removal device for the production of a quickly curable polyurethane waterproof composite material of the present utility model includes a fixing plate 1. A box body is connected to the right side of the fixing plate 1. An air cavity 2 is provided inside the box body. A fan 3 is provided above the air cavity 2. An exhaust port is provided above the fan 3. A rolling door mechanism 4 is provided below the air cavity 2. The right side of the rolling door mechanism is connected to a telescopic rod 5. A filter screen mechanism is provided below the rolling door mechanism 4. The filter screen mechanism includes a movable frame. A first filter screen 6 is installed inside the movable frame. A high-frequency vibrator 7 is installed on the bottom side of the movable frame. Chute grooves are opened at the bottom ends of both sides of the box body. The chute grooves are connected to connection blocks on a collection box 10 through sliders 9. An electrostatic emitter 11 is installed on the bottom side of the collection box 10. Electric grilles 8 are provided on both sides of the box body. The structure of the rolling door mechanism 4 is the same as that of a rolling shutter door and is prior art, so it will not be described in detail here. When dust removal is required, the rolling door mechanism 4 is in an open state, and the fan 3 operates, making the air cavity 2 in a negative pressure state. The first filter screen 6 filters the dust sucked in by the electric grilles 8. When the filter screen needs to be cleaned, the rolling door mechanism 4 operates to separate the box body by the curtain sheet of the rolling door mechanism 4. The high-frequency vibrator 7 is turned on to make the dust on the first filter screen 6 fall. The electrostatic emitter 11 is turned on to adsorb all the floating dust into the collection box 10, achieving the effect of collecting dust and also achieving the effect of cleaning the filter screen, avoiding the work of repeatedly cleaning the filter screen. After the dust in the collection box 10 is collected, pull the handle to draw out the collection box 10 and then pour out the dust. It is convenient and efficient to use and has good practicability. The two sides of the movable frame are the same as the two sides of the collection box 10 in structure, both being connected to the chute grooves through connection blocks. After the high-frequency vibrator 7 is used multiple times, the movable frame can be pulled out for cleaning and washing.
[0019] Further, a second filter screen 12 is installed on one side of the air cavity 2 close to the fan 3. The inner side of the second filter screen 12 is connected to the inner wall of the box body through a slot. Through the secondary interception by the second filter screen 12, the air at the exhaust port can be clean. When the second filter screen 12 needs to be cleaned, the second filter screen 12 can be pulled out from the slot for cleaning.
[0020] Further, the position of the electric grilles 8 is adapted to the position of the first filter screen 6. The electric grilles 8 are located in the middle and lower part of the first filter screen 6. When the electric grilles 8 operate, dust can be sucked in and intercepted by the first filter screen 6.
[0021] Further, the shape of the first filter screen 6 is "T" shaped. The "T" shaped first filter screen 6 can effectively intercept dust.
[0022] Further, an electric check shutter is provided outside the electric grille 8. The electric check shutter can be in an open state or a closed state according to whether it is opened or not. When it is necessary to collect the dust on the first filter screen 6, the electric grille 8 is closed, and the shutter is also closed accordingly, avoiding the overflow of dust during the vibration of the high-frequency vibrator.
[0023] Further, the electric grille 8 is divided into two rows and arranged at equal intervals. The two rows of electric grilles 8 arranged at equal intervals can quickly suck the dust into the box body.
