Description

Technical Field

[0001] This utility model relates to the field of ventilation device technology, and in particular to a ventilation device for an oil production workshop. Background Technology

[0002] The design and operation of the ventilation system in the oil production workshop is of paramount importance, directly affecting production safety, product quality, employee health, and workshop environmental control. During oil production, a large amount of heat and harmful odorous gases are generated in the workshop. Therefore, the oil production workshop needs to be equipped with ventilation devices for effective ventilation to ensure the safety of the workers in the oil production workshop.

[0003] Currently, when industrial centrifugal fans are used in conjunction with ductwork to form ventilation systems in oil and fat production workshops, oil mist and fumes generated in the workshop enter the fans with the airflow, adhering to the impeller, the inner wall of the casing, and the surface of the ductwork, forming viscous grease. This leads to a decrease in the aerodynamic performance of the impeller and a reduction in the cross-sectional area of ​​the ductwork. To address this issue, oil purifiers are installed at the fan ducts in oil and fat production workshops, and metal filters are installed in the fan inlet to intercept residual dust and fumes. However, the fan inlet needs to be connected to the ventilation duct, which makes it inconvenient to directly remove and clean or replace the metal filters when they need maintenance after long-term use. Therefore, we propose a ventilation device for oil and fat production workshops. Utility Model Content

[0004] The main objective of this invention is to provide a ventilation device for an oil production workshop. This device features a pipe filter mechanism installed at the fan body, with a transfer box containing a framed filter screen positioned between the fan body and the ventilation duct. This mechanism performs a three-stage interception of the treated workshop flue gas before it enters the fan body. The transfer box allows for easy removal of the metal support frame for cleaning and maintenance after the top plate is removed. Compared to traditional metal filters installed at the fan body's inlet duct, the pipe filter mechanism makes the filtration structure near the fan body easier to maintain and clean. Furthermore, the three-stage interception of the treated workshop flue gas before the fan body significantly reduces the total amount of pollutants entering the fan body, thus significantly reducing the frequency of fan downtime due to oil mist blockage. This effectively solves the problems described in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A ventilation device for an oil production workshop includes a fan body with an air inlet pipe fixed at the air inlet of the fan body. It also includes a pipe filter mechanism, comprising a transfer box, a T-shaped pipe coil, a support frame, a box plate, a metal support frame, a framed filter screen, and a top plate pin. T-shaped pipe coils are welded to both sides of the transfer box away from its opening, and one side of the T-shaped pipe coil is connected to the air inlet pipe via bolts and nuts. The opening of the transfer box is widened for mounting the support frame. The box has a flared groove and a support frame welded to the surface of the box panel. Metal support frames are welded to the box panel inside the support frame, and a framed filter screen is bolted to the side frame opening of the metal support frame. A guide groove for mounting the metal support frame is recessed in the transfer box on one side of the flared groove. An L-shaped socket is symmetrically welded to the top of the transfer box above the box panel, and a gradient groove seat is vertically symmetrically welded to the outer side of the box panel below the L-shaped socket. A top plate pin is vertically inserted between the L-shaped socket and the gradient groove seat.

[0007] Furthermore, a hole for a bolt to pass through is provided between the disc body of the T-shaped tube disc and the disc body of the air intake pipe, and the bolt passing through between the T-shaped tube disc and the air intake pipe is screwed into a nut.

[0008] By adopting the above technical solution, bolts are passed through the holes on the surface of the T-shaped tube disc and the air intake pipe, and then nuts are screwed in to lock them, so that the T-shaped tube disc on one side of the transfer box and the air intake pipe can be locked and connected.

[0009] Furthermore, a rubber sealing ring is fitted on the outer side of the support frame, and the body of the rubber sealing ring is engaged between the support frame and the flared groove.

[0010] By adopting the above technical solution, after the rubber sealing ring is fitted onto the outside of the support frame, the support frame presses down on the rubber sealing ring, which can be locked in the flared groove for sealing.

[0011] Furthermore, a railing is fixed inside the frame opening of the metal support frame, and a frame groove for mounting the metal frame body of the framed filter is provided on the side of the metal support frame away from the railing. An installation hole for screwing bolts is provided between the metal frame body of the framed filter and the metal support frame.

[0012] By adopting the above technical solution, the framed filter screen can be snapped into the frame groove of the metal support frame. After being snapped in, bolts can be screwed between the metal frame of the framed filter screen and the metal support frame for locking installation.

[0013] Furthermore, the metal support frame outside the framed filter screen has symmetrically raised edge strips on both sides, and the edge strips of the metal support frame press against the inner wall of the transfer box on both sides of the guide groove.

[0014] By adopting the above technical solution, the framed filter screen is supported by the edge pressure strips pressing against the inner wall of the transfer box on both sides of the guide groove, so that the framed filter screen can obtain stable support in the transfer box.

[0015] Furthermore, the top plate pin has a rectangular rib protruding from the vertical pin plate for mounting the L-shaped socket, and the top plate pin below the rectangular rib has symmetrically protruding opposing blocks for mounting the gradient slot seat. The dimensions of the two sets of opposing blocks on the surface of the top plate pin gradually decrease from top to bottom.

[0016] By adopting the above technical solution, the vertical pin plate of the top plate pin can be engaged with the L-shaped socket by means of rectangular ribs. Then, the vertical plate of the top plate pin and the two sets of tapered blocks of the top plate pin can be fitted and engaged in the gradient slot seat.

[0017] Furthermore, a handle is welded to the center of the back panel of the box panel away from the support frame, and the handle body is an I-shaped handle body.

[0018] By adopting the above technical solution, by holding the handle of the box plate, it is convenient to pull the box plate with the release pin outward, thereby pulling the metal support frame out from the guide groove.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model introduces a pipe filter mechanism at the fan body used for ventilation in an oil production workshop. The pipe filter mechanism has a transfer box containing a framed filter screen between the fan body and the ventilation duct. It performs three-stage interception of the treated workshop flue gas before it enters the fan body. The metal support frame supporting the framed filter screen can be directly pulled out for cleaning and maintenance after the top plate is removed. Compared with the metal filter screen set at the air inlet duct of the traditional fan body, the pipe filter mechanism makes the filtration structure near the fan body easier to maintain and clean.

[0021] Furthermore, after the flue gas in the workshop is treated in front of the fan body, it is intercepted in three stages by the frame filter screen, which greatly reduces the total amount of pollutants entering the fan body and significantly reduces the frequency of downtime maintenance caused by oil mist blockage of the fan body.
